Soil carbon sequestration has long been championed as a promising strategy for mitigating climate change. By drawing carbon dioxide (CO₂) from the atmosphere and storing it in soils through plants and organic matter, this process is often seen as a natural solution to reduce greenhouse gas concentrations. However, a recent comprehensive review by Don et al. (2023) reveals that the role of soil carbon sequestration is frequently misunderstood, miscommunicated, and, at times, overstated in its potential to counter climate change.

Effective water management is vital for sustainable agriculture. This project introduces an IoT-based, AI-driven irrigation system that optimizes valve control using real-time soil moisture data. Soil moisture sensors continuously assess root zone moisture and relay this data to an AI framework, determining precise irrigation needs. The system autonomously adjusts valves according to environmental conditions, minimizing water waste and enhancing crop hydration. Machine learning algorithms, notably the random forest algorithm, analyze soil moisture and weather variables to inform irrigation schedules.

Sources of soil contamination can exist in various types of conditions including in the form of semifluids. In this study, 3 different types of tropical plants, Acacia (Acacia mangium Willd), Mucuna (Mucuna bracteata DC. ex Kurz) and Vetiver (Vetiveria zizanioides L. Nash), were tested under different levels of soil-leachate conditions. The relative growth rate, metal tolerance, and phytoassessment of cadmium (Cd) and lead (Pb) accumulation in the roots and shoots were determined using flame atomic absorption spectrometry. Tolerance index, translocation factor, (...) metal accumulation ratio, and percentage metal efficacy were applied to assess the metal translocation ability among all the 3 types of plants. Significantly higher (P < .05) accumulation of Cd and Pb was exhibited in the roots and shoots of all 3 plants growing under the soil-leachate conditions. However, negative growth performance and plant withering were observed in both Acacia and Mucuna with increased application of higher soil-leachate levels. Vetiver accumulated remarkably higher total concentration of Cd (116.16-141.51 mg/kg) and Pb (156.37-365.27 mg/kg) compared with both Acacia and Mucuna. The overall accumulation trend of Cd and Pb in the 3 plants growing under the soil-leachate conditions was in the order of Vetiver > Acacia > Mucuna. The findings of the study suggest that Vetiver has great potential as Cd and Pb phytoremediator in soil-leachate conditions. (shrink)

In the face of climate change and dwindling agricultural productivity, regenerative farming has emerged as a promising alternative to conventional agriculture. This approach prioritizes ecological balance, soil health, and biodiversity, aiming not just to sustain but to regenerate the land.

Many of the most important questions about primitive certainty have to do with the distinction between primitive certainty as a practical attitude or disposition and primitive certainty as a psychological attitude and with the distinction between these and primitive, objective certainty.

Three different types of low cost soil amendments, namely, EDTA, elemental S and N-fertilizer, were investigated with Vetiver grass, Vetiveria zizanioides (Linn.) Nash growing under highly mixed Cd–Pb contamination conditions. A significant increase (p < 0.05) in Cd and Pb accumulation were recorded in the shoots of all EDTA and N-fertilizer assisted treatments. The accumulation of Cd in 25 mmol EDTA/kg soil and 300 mmol N/kg soil showed relatively higher translocation factor (1.72 and 2.15) and percentage metal efficacy (63.25 % (...) and 68.22 %), respectively, compared to other treatments. However, it was observed that the increased application of elemental S may inhibit the availability of Pb translocation from soil-to-root and root-to-shoot. The study suggests that viable application of 25 mmol EDTA/kg, 300 mmol N/kg and 20 mmol S/kg soil have the potential to be used for soil amendment with Vetiver grass growing under contaminated mixed Cd–Pb soil conditions.

The way we farm, the kinds of backyards and landscapes we favor, and the way we control patterns of development are creating an invisible crisis through their affects upon soil ecology. The invisibility of soil ecosystems, the seemingly alien properties of the organisms that inhabit them, and the specialized knowledge required to understand them create obstacles to moral concern for these fountains of life. Our treatment of soils has reached the point of crisis. Obstacles to moral thinking about (...) class='Hi'>soils might be overcome by supplying the moral imagination with a deeper understanding of our own biological identity as ecosystems analogous in organization and functions to soil ecosystems. Not only have microbes created the conditions necessary for human life, but they have shaped our evolutionary history and helped constitute the human genome. Our biological identity encompasses communities of microbes, such that humans (and all organisms) are most properly understood as ecosystems. For this reason, moral concern for humans implies moral concern for ecosystems. (shrink)

Many twentieth-century accounts of history have used geological tropes to describe the phenomenon of historical knowledge, and such terms have been of particular importance in the phenomenological tradition. In Heidegger's references in Being and Time to the "soil of history," Husserl's account in his later work of "sedimentation" in the lifeworld, and the reformulation of this notion in the phenomenology of Merleau-Ponty, geological tropes are used to illustrate important insights into the relation between contingency, a priority and historicity. This paper (...) seeks to contribute to an understanding of history understood phenomenologically as historicity through an analysis of these geological tropes. I argue that such geological tropes help the phenomenologist to describe the way in which history is always determined within a complex interplay between only temporarily fixed determining structures - such as riverbanks, insoluble sediment, soil, etc. - and free-flowing praxis, a situation in which historical events are at once determinant of and themselves determined by human activity. Paradoxically, the constant and "grounding" element in such conceptions of history is not the sediment and hard rock of historical fact, but the the constant change and variability-despite the sense giving continuity - of human experience structured by historicity. I begin with a brief overview of the landscape on the philosophy of history in which these views arose, and then continue to an analysis of the tropes themselves. (shrink)

Soils are far more than just the ground beneath our feet—they are among Earth’s largest carbon reservoirs, holding more than twice the amount of carbon found in the atmosphere. Yet, this vital carbon store is increasingly under threat. A recent study by De Rosa et al. (2024) provides a comprehensive assessment of soil organic carbon (SOC) dynamics in European croplands and grasslands over the past decade, revealing both concerning trends and promising opportunities for climate action.

This short piece of communication has the sole purpose of identifying some evidence, supporting our view regarding a possible missing environment-nurturing cultural value. Here, we attempt to examine the existence of cultural research within the boundary of soil degradation, erosion, and pollution topic.

Over the years, ethylene-diamine-tetra-acetate (EDTA) has been widely used for many purposes. However, there are inadequate phytoassessment studies conducted using EDTA in Vetiver grass. Hence, this study evaluates the phytoassessment (growth performance, accumulation trends, and proficiency of metal uptake) of Vetiver grass, Vetiveria zizanioides (Linn.) Nash in both single and mixed heavy metal (Cd, Pb, Cu, and Zn)—disodium EDTA-enhanced contaminated soil. The plant growth, metal accumulation, and overall efficiency of metal uptake by different plant parts (lower root, upper root, lower (...) tiller, and upper tiller) were thoroughly examined. The relative growth performance, metal tolerance, and phytoassessment of heavy metal in roots and tillers of Vetiver grass were examined. Metals in plants were measured using the flame atomic absorption spectrometry (F-AAS) after acid digestion. The root-tiller (R/T) ratio, biological concentration factor (BCF), biological accumulation coefficient (BAC), tolerance index (TI), translocation factor (TF), and metal uptake efficacy were used to estimate the potential of metal accumulation and translocation in Vetiver grass. All accumulation of heavy metals were significantly higher (p < 0.05) in both lower and upper roots and tillers of Vetiver grass for Cd + Pb + Cu + Zn + EDTA treatments as compared with the control. The single Zn + EDTA treatment accumulated the highest overall total amount of Zn (8068 ± 407 mg/kg) while the highest accumulation for Cu (1977 ± 293 mg/kg) and Pb (1096 ± 75 mg/kg) were recorded in the mixed Cd + Pb + Cu + Zn + EDTA treatment, respectively. Generally, the overall heavy metal accumulation trends of Vetiver grass were in the order of Zn >>> Cu > Pb >> Cd for all treatments. Furthermore, both upper roots and tillers of Vetiver grass recorded high tendency of accumulation for appreciably greater amounts of all heavy metals, regardless of single and/or mixed metal treatments. Thus, Vetiver grass can be recommended as a potential phytoextractor for all types of heavy metals, whereby its tillers will act as the sink for heavy metal accumulation in the presence of EDTA for all treatments.

Agricultural mulch films—those thin plastic layers often seen blanketing fields of strawberries, tomatoes, or other high-value crops—have long played a vital role in enhancing farm productivity. By conserving soil moisture, suppressing weed growth, and boosting crop yields, these films have become essential tools in modern agriculture. However, conventional plastic mulches (PMs), typically made from fossil-derived polymers like polyethylene, have raised significant environmental concerns due to their persistence in soils and the challenges associated with their disposal.

Tropical grasses are fast growing and often used for phytoremediation. Three different types of tropical grasses: Vetiver (V. zizanoides), Imperata (I. cylindrical) and Pennisetum (P. purpureum) tested in different growth media of spiked heavy metal contents under the glasshouse environment of RimbaIlmu for 60-day. The growth performance, metals tolerance and phyto-assessment of cadmium (Cd), lead (Pb), zinc (Zn) and copper (Cu) in shoots and roots were assessed using flame atomic absorption spectrometry (FAAS).Tolerance index (TI), translocation factor (TF), biological accumulation coefficient (...) (BAC), biological concentration factor (BCF), and uptake efficacy was applied to evaluate the metal translocation ability among all three grasses. All three grasses showed significantly higher (p<0.05) accumulation of the total heavy metals in the spiked metal treatment compared with other tested treatments. Vetiver accumulated remarkably higher total concentration of Cd (93.08 ± 3.81 mg/kg) and Zn (1284.00 ± 234.83 mg/kg) than both Imperata and Pennisetum. The overall trend of heavy metals accumulation for all three grasses followed the order of Zn>Pb>Cd>Cu. The results of study suggested that both Imperata and Pennisetum are commendable and potential phytoextractors for Zn as well as phytostabilizers for Cd, Pb and Cu, respectively. (shrink)

Soil microbes play a pivotal role in the Earth’s carbon cycle, yet not all microbial carbon processing functions the same way. A comprehensive global meta-analysis by Sun et al. (2025) reveals that soil microorganisms utilize carbon through two fundamentally different pathways—exogenous (external carbon inputs, such as plant litter) and endogenous (internal soil carbon reserves)—and that these pathways respond differently to environmental pressures.

This study used a flame atomic absorption spectrometer (FAAS) and atomic fluorescence spec-trophotometer (AFS) to detect the concentrations of chromium (Cr), cadmium (Cd), lead (Pb), hy-drargyrum (Hg) and arsenic (As) in soils and three genotypes of vegetables in greenhouse, as well as analyzed the physical and chemical properties of soils, including soil pH, soil organic matter (OM), basic nutrients, electrical conductivity (EC) and cation exchange capacity (CEC) in Guan- zhong areas, Shaanxi province, China. The results showed that comparing (...) to subsoil, the sampled topsoil is enriched in Cr, Cd, Pb, As and Hg. Cd (0.83 - 3.17 mg·kg-1) and Hg (0.40 - 1.44 mg·kg-1) are exceeding the limited value stated in “the 2006 Greenhouse Vegetable Producing Environmental Quality Evaluation Standards” of 0.40 mg·kg-1 and 0.35 mg·kg-1 respectively. However, Nanzhuang greenhouse soil is within the limits. The heavy metal pollution index (HPI) of soil in Sanyuan (8.10) is the highest and in Dongzhang (4.23) is the lowest. The contents of Pb (0.201 - 0.376 mg·kg-1) were exceeding the limited value (0.20 mg·kg-1) in vegetables species, and Cd (0.0363 - 0.0572 mg·kg-1) in some place were also exceeding the limited value (0.05 mg·kg-1). Greenhouse soils were becoming acidified year after year; the ratios of N, P and K in soil were seriously imbalanced. According to the impacting factors, OM, pH, available P, EC and CEC have obviously effected the accumulation of Cr and Hg. However, there was not enough evidence for the effects of available nitrogen and available potassium. (shrink)

As urban areas expand, their influence extends far beyond visible infrastructure—reaching deep into the very soil that supports ecosystems. A recent study by Zheng et al.

Abstract: Northern state, Sudan is extremely affected by desertification and Salinization processes, there for this study aimed to investigate an effective method to improve the salt affected soil. Two field experiments were carried out in two successive seasons ( July 2005 – June 2006 ) at Dongola University farm, in the North State to investigate the effect of irrigation frequency ( 7 and 14 days ) and farm yard manure (M0 , M1 , M2 , andM3 ) on salt leaching (...) undersaline – sodic soil . The experiment was designed in spilt – plot design , where irrigation frequency was assigned in the main plots ( 6x28m) and farm yard manure were the sub – plots ( 6x7m) .The total cultivated area was 1342m2 for each experiment. The quantity of water applied was estimated according to Jensen andHaise (1963 ) . The total water quantity was the same by the end of the season. In general , the result indicated that irrigation frequency of 7 days enhanced salt leaching from the root zone. Generally , the reduction in electrical conductivity ( ECe ) and sodium adsorption ratio ( SAR ) due to irrigation frequency was more effective in 7 day irrigation interval as compared with 14 – day irrigation interval . the data obtained indicated that the addition of FYM 10 ton/feddan, significantly degreased the (ECe) and the (SAR) and leached them below the root zone. So, we can conclude that the efficiency of salt leaching is markedly affected by irrigation frequency and yard manure. (shrink)

As populations grow and arable land becomes increasingly scarce, large-scale long- term land leases are signed at a growing rate. Countries and investors with large amounts of financial resources and a strong agricultural industry seek long-term land leases for agricultural exploitation or investment purposes. Leaders of financially poorer countries often advertise such deals as a fast way to attract foreign capital. Much has been said about the short-term social costs these types of leases involve, however, less has been said about (...) the normative dimension of their long-term environmental impact. We therefore will focus on the likely impact such deals have for soil conservation, by (1) briefly introducing the basics of long-term leasing arrangements by comparing land leases to the renting of buildings, (2) explaining from a soil sciences perspective the difficulties in assessing the current value of an estate and in calculating the damages of soil erosion and degradation, and (3) show how difficult it is to incentivize the conservation of soil quality when one cannot sufficiently and cost-effectively valorize existing environmental capital and eventual future damages. Attempting to oblige tenants through contracts to invest in sustainable stewardship has limited potential when liability payments do not reflect true costs and are hard to enforce. (shrink)

The impact of crude oil on the permeability of the soil in a non oil producing community in Enugu State was investigated using disturbed A 6 CL soil sample collected from Ibagwa Nike area of the state. The sample was divided into five 5 portions and each of the four 4 portions was dosed with Bonny light crude oil at 2 , 4 , 6 and 8 by weight of the samples. The physical properties of the uncontaminated soil were tested (...) and analyses and used as control. The aim of the laboratory investigation was to determine the effects of crude oil on the permeability of the soil. The permeability of the uncontaminated soil was found to be 1.2609x10 7. Permeability tests were also conducted on the contaminated soil samples at the various percentage contaminations. The results showed that at 2 crude oil contamination the permeability was 9.6403x10 9, a drastic reduction. The other results were 6.9600x10 6, 2.2621x10 8 and 9.1286x10 8 at 4 , 6 , and 8 contamination levels, respectively. The ranking after contamination is seen to drop within the range of 10 8 and 10 9 showing a change in the permeability due to oil content. This observed reduction in permeability alters the natural groundwater recharge which can be remedied by enhanced bioremediation through aeration of the soil. Iloeje A. F. | Aniago V.

Phytoremediation is a biological remediation technique known for low-cost technology and environmentally friendly approach, which employs plants to extract, stabilise, and transform various compounds, such as potentially toxic elements (PTEs), in the soil or water. Recent developments in utilising chelating agents soil remediation have led to a renewed interest in chelate-induced phytoremediation. This review article summarises the roles of various chelating agents and the mechanisms of chelate-induced phytoremediation. This paper also discusses the recent findings on the impacts of chelating agents (...) on PTEs uptake and plant growth and development in phytoremediation. It was found that the chelating agents have increased the rate of metal absorption and translocation up to 45% from roots to the aboveground plant parts during PTEs phytoremediation. Besides, it was also explored that the plants may experience some phytotoxicity after adding chelating agents to the soil. However, due to the leaching potential of synthetic chelating agents, the use of organic chelants have been explored to be used in PTEs phytoremediation. Finally, this paper also presents comprehensive insights on the significance of using chelating agents through SWOT analysis to discuss the advantages and limitations of chelate-induced phytoremediation.

Monitoring soil pH levels forms the backbone of precision agriculture with regard to maximizing crop health and yield. The paper discusses an IoT-based solution, specifically designed for continuous soil pH testing in digital farming. It has pH sensors placed strategically around the agricultural fields such that the information regarding the acidity or alkalinity of the soil is available in real-time. The pH information will be transmitted to the central IoT gateway. Here, the information is processed, and via communication of cloud-based (...) platforms, it is further stored and analyzed. So, by checking variations in soil pH, the system provides actionable information to farmers. Thus, by adjusting soil treatments like lime or fertilizers better, it enhances crop performance. The response uses mobile and web interfaces that support automated pH testing with automatically designed data visualization. This allows farmers the chance to decide from remote sites about imminent and proper fluctuations in soil pH by the use of historical data analysis and models from machine learning. One part of the effectuality of this proactive approach would be that soil quality is improved while unnecessary chemical use is avoided, therefore reducing the resulting costs of farming with sustainability considerations. By limiting itself to pH value testing, this solution increases the farmland's productivity with less wastage of resources. (shrink)

Various types of plant species have been extensively used for heavy metals phyto-remediation without taking into consideration its tolerance threshold. In this study, Vetiver grass, Vetiveria zizanioides (Linn.) Nash was evaluated under five different sets of contaminated spiked cadmium (5Cd, 10Cd, 50Cd, 100Cd and 150Cd mg/kg) and lead (50Pb, 100Pb, 200Pb, 400Pb and 800Pb mg/kg) concentration levels in soil. The growth performance, metal tolerance and phyto-assessment of Cd and Pb in the roots and tillers were assessed using flame atomic absorption (...) spectrometry (FAAS). Tolerance index (TI), translocation factor (TF), biological transfer factor (BTF), biological accumulation coefficient (BAC) and metal uptake efficacy were used to determine the Cd and Pb translocation capability in Vetiver grass. Significantly higher (p<0.05) accumulation of Cd and Pb was recorded in the roots of all spiked treatments. Furthermore, strong and significantly positive correlations were exhibited between the increased levels of spiked heavy metal concentrations with both Cd (r=0.975) and Pb (r=0.952) accumulations. The results of this study showed Vetiver grass as an effective phyto-stabilizer for both Cd and Pb. Nevertheless, the growth of Vetiver grass was restricted when the tolerance threshold of 100 mg/kg (dry weight basis) Cd was exceeded in the contaminated soil. (shrink)

In today's agricultural landscape, farmers face numerous challenges in selecting the right crops to plant, primarily due to varying soil conditions and unpredictable weather patterns. This often leads to suboptimal yields and inefficient use of resources. To tackle these issues, we propose a Crop Recommendation System powered by machine learning, specifically utilizing the Random Forest algorithm. This innovative system will analyze essential factors such as soil nutrients—nitrogen, phosphorus, and potassium—as well as climatic conditions like temperature, humidity, and rainfall, to provide (...) tailored crop recommendations. Our goal is to empower farmers by simplifying the decision-making process, ensuring they have access to reliable guidance for improving crop selection. By making informed decisions, farmers can boost their yields, enhance sustainability, and ultimately contribute to a more efficient agricultural sector. This project not only aims to improve individual crop management practices but also supports researchers and policymakers in developing better agricultural strategies. Through this initiative, we hope to pave the way for a future where technology and agriculture work hand in hand for a more sustainable and productive world. (shrink)

The foundation of a building connects the main body superstructure to the ground. Every form of foundation and footing have a unique application in a given location for a certain weather condition. Understanding the foundation work is crucial for carrying out building activities. Due to the variety of structures they support, foundations are frequently built in different subsoil conditions and are exposed to static loads. The proper evaluation of soil-bearing capacity is fundamental to the construction of various buildings. One of (...) the quick, easy, and affordable ways to determine soil carrying capacity is the plate load test. The effect of subsoil conditions on the test results is assessed and analyzed in thorough parametric investigations. An overview of axial static and dynamic plate load testing will be given in this study. This article presents detailed processes and schematics. In an effort to highlight the differences and shared characteristics of the results, computational test results of the static load plate test and the dynamic load plate test are contrasted. A load cell, a steel plate, a hydraulic actuator mounted on a big truck to apply a load, a load cell to measure the load, and one or more linear variable displacement transformers to measure the vertical displacements make up the test setup. The maximum thrust load that should be applied to a fixed or stationary actuator when it is not moving is known as a "static load depending on the actuator's static load capacity, we can determine what a safe load is. The maximum thrust load that should be applied to the actuator while it is moving is known as a dynamic load. Dynamic load capacity refers to how much force an actuator can exert when driven and extending or retracting. With each method's benefits and drawbacks considered, it can be determined that using them in various situations and agreeing to the confrontation of these tests for the purpose of comparing results is the best course of action in order to have a base that satisfies the construction standards.

Soil is far more than just the ground beneath our feet—it is one of the planet’s largest and most important carbon reservoirs. Remarkably, more than two-thirds of all agricultural land worldwide is used for livestock grazing, positioning grazing as a significant factor influencing the fate of soil carbon. This reality has fueled growing interest in whether improved grazing practices could enhance soil carbon storage and contribute meaningfully to climate change mitigation.

Abstract: A corn crop typically refers to a large-scale cultivation of corn (also known as maize) for commercial purposes such as food production, animal feed, and industrial uses. Corn is one of the most widely grown crops in the world, and it is a major staple food for many cultures. Corn crops are grown in various regions of the world with different climates, soil types, and farming practices. In the United States, for example, the Midwest is known as the "Corn (...) Belt" due to its extensive corn production. Corn crops can be grown using a variety of methods, including conventional tillage, no-till farming, and the use of genetically modified crops. Due to its importance, there is a need for discovering the corn diseases and treating them. The aim of this study is to propose a deep learning model for the classification of corn leaf diseases based on Convolutional Neural Network. A model for classifying maize diseases was developed using a dataset for classifying Corn diseases that contains 4 classes of disease. The dataset was collected from Keggel website. The proposed model was trained, validated, and tested. The F1-score (99.83%), Recall (99.83%), precision (99.83%), Accuracy (99.83%). (shrink)

The article offers an attempt to understand the present state of Kant’s legacy in Russia on the threshold of the Tercentenary. An explanans is found in the metaphors of “ tabula rasa ” and “unplowed virgin soil,” first used by Leibniz in relation to Russia in his letters and memoranda addressed to tsar Peter I and other members of the Russian elite, which became the country’s “absolute metaphors to live by” up to present time. Several known and unknown episodes from (...) the history of the reception of Kantian ideas, his followers in Russia, and the transformation of the urban environment of Kant’s life in Königsberg, as it was becoming Kaliningrad, are presented through the prism of this metaphor. Without hoping to make specific recommendations of any use from such metaphorical grounds, this study aims to emphasize the depth, interconnectedness, and basic, metaphysical tension of the relationship between Europe and Russia, which cannot be terminated at will by either side, or by a third party. In a situation where the sides are doomed to dialog, Kant, appropriated by Russia as its “subject,” occupies the unique position of mediator of philosophical understanding and peaceful action.

This work is driven by the attempt to criticise Phenomenology with the help of Levinas. Similar to the Frankfurt School, he characterises it as a “vision of essences”. These eidetical essences are, and can never be fully absolute, not only because several movements of Hegelian Dialectics are refuted in submitting knowledge either to the imago of mere immanence, or to normative structures which are postulated as invariant like in certain versions of Neoplatonism, but because they function as an apriori of (...) an eternally unfinished and fragmented Lebenswelt. Maybe it is to harsh to compare Husserl to the neoscholastic readings of Descartes and to the formalist interpretations of Kant. Husserl is well aware of the kinaesthetic foundations of consciousness and, contrary to Heidegger, he even promotes Spinozism in a certain phase of his work which excels his adolescent fervour of Berkeley. Nevertheless, Husserl incorporates a subject-based, “monadic” transcendentalism, that paradoxically leads to the dissolution of subjective identity. Traditional reasoning itself is exfoliated to perfection in Heidegger afterwards. Husserl's halfhearted formalism ignores the materialist theory of the simulacrum by Lucretius. Heideggers philosophy widens this overseen aspect in calling the Eidos an Aussehen in referring to the Presocratics, but it despises any kind of method and finally flees in to poetry, maintaining its fatalist errors which it committed right form the start: this is why it gained the name of pseudo-concreteness. Cursed through a specific anti-sociological tendency caused by an anti-empiricist vision of history, their theories virtually (not conceptually) exclude the influences of society on philosophy: they are the end result of the era of Kulturkampf, in which idealism tried to battle positivism, naturalism and historicism. Husserl even defines this philosophical battle as the very struggle of existence. The formulation of the Eidos becomes performance. Aristotle used Eidos synonymous to genus and species. Hence the amplitudes of these philosophies foster the metaphysical standpoint of race, that got out of hand in the Nazi Era and even later on. The “topic” of blood and soil appears in Husserl's definition of Heimwelt and his Eurocentrism. Phenomenology is in no case to blame for National Socialism, and it has very little to to with its causes. My work simply tries to make the same analogy that Marx had made for Hegel. It tries to describe, how two leading philosophers of the German Bourgeoisie are reproducing the categories of their surrounding society without even really observing it. (shrink)

Home gardens serve as dynamic interfaces between environmental sustainability and human health, providing active, immersive engagement with nature. This review examines the extensive biological and psychological benefits of gardening, positioning it as more than a leisure activity but a transformative health practice. Biologically, home gardens reconnect individuals with soil microbiota, enhancing immune function, regulating endocrine responses, and improving air quality. Psychologically, gardening fosters mindfulness, emotional stability, cognitive function, and social cohesion, reducing stress, anxiety, and depression. These findings suggest that human (...) care for nature reciprocally enhances personal health and community resilience. Thus, integrating gardening into public health policy through urban planning, healthcare prescriptions, and community initiatives could yield significant benefits for human well-being. Future research should explore optimal engagement levels, long-term health effects, and technological advancements that enhance accessibility. As evidence grows, it strengthens the case for home gardening as a key public health and sustainability strategy, demonstrating that tending to nature at home fosters both personal well-being and environmental enrichment.

Ethics normally proceeds by establishing some kind of ground from which norms can be derived for human action. However, no such terra firma is found in Jean-Paul Sartre’s Being and Nothingness, which instead lays down a sedimentary soil consisting of a blend of nothingness and contingency. This paper aims to show how Sartre is able to build an ethical theory from this seemingly groundless mixture, and it proceeds in three sections. Section one aims to disentangle the relation between the for-itself (...) (pour-soi) and the in-itself (en-soi) from antithetical characterizations by placing them in a state of supervenience. Section two works to explain how both the in-itself and the for-itself are not divided ontologically, but are both in the same ontological state, namely, contingency. And in section three, it is argued that Sartre’s ethics reveals that because human beings share the same thrownness with Others in a world, they have to take title for such a world. Within a Sartrean ethics of nothingness, one’s nothingness leads one to the shared nothingness of Others, of which one must take responsibility. (shrink)

Informed by his experiences as a hunter, forester, wildlife manager, ecologist, conservationist, and professor, Aldo Leopold developed a view he called the land ethic. In a classic essay, published posthumously in A Sand County Almanac, Leopold advocated for an expansion of our ethical obligations beyond the purely human to include what he variously termed the “land community” or the “biotic community”—communities of interdependent humans, nonhuman animals, plants, soils, and waters, understood collectively. This philosophy has been extremely influential in environmental (...) ethics as well as conservation biology and related fields. Using an approach grounded in environmental ethics and the history and philosophy of science, Roberta L. Millstein reexamines Leopold’s land ethic in light of contemporary ecology. Despite the enormous influence of the land ethic, it has sometimes been dismissed as either empirically out of date or ethically flawed. Millstein argues that these dismissals are based on problematic readings of Leopold’s ideas. In this book, she provides new interpretations of the central concepts underlying the land ethic: interdependence, land community, and land health. She also offers a fresh take on of his argument for extending our ethics to include land communities as well as Leopold-inspired guidelines for how the land ethic can steer conservation and restoration policy.

When I explore my own nature, or experience the sacred, most often I find darkness. Although dominating theologies create binaries, in which light is holy is and darkness is evil, when we recognize the multivalent nature of all that is, we see wave upon wave of dark and light, through varied sacred paths. In darkness, all separation dissolves into oneness. Darkness is depths, womb, soil where seeds sprout, soothing shade, night in which we grow and make long-term memory. Darkness is (...) source, essence, innermost depths, transcendence, nothingness, emptiness, mystery. When we discount the power of darkness, we devalue all one might associate with it—dark skin, women, and the earth. Audre Lord wrote: “The woman's place of power within each of us is neither white nor surface; it is dark, it is ancient, and it is deep.” We need the holiness, and the liberating power, of deepening into the dark. Jewish tradition evokes many forms of sacred darkness. Nighttime study brings a thread of loving-kindness into the world. Divine presence can be a sheltering shade. Revelations occur at caves. Torah was received in darkness, formed of black fire on white fire, and still the ink is black. Before G-d said “Let there be light” there was already darkness, the darkness of wisdom. The infinite source of all is imagined as a burning black coal or a deep spring. These images, and the texts that hold them, are openings that take us deeper into the sacred. (shrink)

There is a need for enterprises to incorporate information on the environment into decision making and to take action on ecological restoration. Within academia, a comprehensive understanding of the impacts on how business can serve sustainability transformation is still lacking as diverging holistic approaches and reductive approaches cloud academic thinking. The authors take a science-policy interface perspective to cover the role of cognitive proximity, matching and coordination of scientific knowledge from diverse stakeholders for effective policy making and implementation. We show (...) through a literature review that temporal and spatial scales, soil and land degradation, institutions and ecosystem, and the role of human behavior and narrative are not adequately emphasized in sustainability research. A scale-based picture, focusing on landscapes, institutions and practices is proposed which can be used to align diverse fields by acting as “bridge” for improved science policy interface and decision making, facilitated through cognitive proximity, matching, and coordination. A case study on a business association from South India is used to demonstrate the scales based approach in practice. A scale-based approach can play a key role in connecting human behaviour, a social science thematic topic, with ecosystems, a natural science thematic topic. (shrink)

This project focuses on estimating reservoir inflows by integrating rainfall data, soil moisture levels in the catchment area, and releases from upstream reservoirs, coupled with an automated gate control system to prevent flooding in the basin. Utilizing hydrological models, the methodology predicts runoff from rainfall, adjusted for current soil moisture to enhance accuracy. Real-time data from upstream releases further refines inflow predictions. The automated system leverages predictive analytics and real-time monitoring to optimize gate operations, ensuring moderate water releases to maintain (...) safe reservoir levels and mitigate downstream flooding. This approach aims to enhance flood management and sustainable water resource use through advanced modelling and automation. (shrink)

Given that one-million species are currently threatened with extinction and that humans are undermining the entire natural infrastructure on which our modern world depends (IPBES, 2019), this dissertation will show that there is a need to provide an alternative approach to wildlife conservation, one that avoids anthropocentrism and wildlife valuation on an instrumental basis to provide meaningful and tangible success for both wildlife conservation and human well-being in an inclusive way. In this sense, The Value of Being Wild will showcase (...) the concept of eco-phenomenology as an important non-anthropocentric alternative to the current approach to wildlife conservation, namely sustainable development. The problem with this dominant paradigm, as Chapter Two will reveal, is that sustainable development has not only failed to provide humans and future generations of humans with their own needs but, as per the latest IPBES report, failed in arresting the freefall decline of wild species. The situation currently requires a radical overhaul of the current system. As emerged from the later work of French phenomenologist, Maurice Merleau-Ponty (1908-1961), eco-phenomenology is particularly well-suited as a practical alternative to sustainable development. The core reason is that eco-phenomenology moves away from a human-centred framework toward a far more inclusive approach that embraces the conservation of wild animals as well the wild environment they dwell in, beyond any human needs (although humans are embraced within the approach too). Merleau-Ponty helps us to move away from anthropocentrism to a more inclusive approach in conserving wildlife, since his phenomenology does not consider the human animal’s relationship in the world as exclusive (to use and exploit wild animals solely for their benefit), but inclusive (as an interconnected biological component in a broad ecological system). The strength of Merleau-Ponty’s concept of phenomenology is that it facilitates an understanding of all living and even non-living entities, such as air, water and soil, as interconnected and interrelated within a broad biosphere. While Merleau-Ponty did not address the concept of wild animals or the biosphere directly, his later work points to the fact that human animals cannot exist outside a world that provides life-giving force to all living beings. Phenomenology, as developed by Merleau-Ponty, is a concept that recognises the axiological qualities of the natural world are inherent and ineliminable from the discipline of traditional phenomenology, hence the term ‘eco-phenomenology’, developed in one reception of his thinking. Eco-phenomenology offers a return to a world that humans have tried hard to alienate themselves from, in that it approaches the natural environment and wild animals, not as a complex set of objects and objective processes, but rather as they are experienced and lived from within by the attentive animal who is entirely a part of the world that he or she experiences. Merleau-Pontian eco-phenomenology thus emphasises a holistic dialogue within a more-than-human world (Abram, 1996: 65). Eco-phenomenology is a concept that points toward an applied strategy but so far this has not been attempted in earnest. This is specifically true when it comes to wildlife conservation. The Value of Being Wild, therefore, sets out to employ the concept of eco-phenomenology in order to provide a new practical wildlife conservation approach that challenges, and potentially replaces, the current prevailing policies as employed by global governmental and inter-governmental agencies. In particular, this alternative frame is posed as a replacement for the failing anthropocentric conservation practices currently in place in South Africa. This dissertation will therefore conclude by exploring strategies where conservation of wildlife is not taken as instrumentally-valued, or even intrinsically-valued, but rather as wild-valued in that the existence of wild animals as wild is conserved within a broader, more inclusive overall ecology that supports the survival and flourishing of all living beings that include plants, wild animals and human beings.

The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection and measurement protocols. A review of the current landscape of metadata standards and ontologies in biodiversity science suggests that existing standards such as the Darwin Core terminology are inadequate for describing biodiversity data in a semantically meaningful and computationally useful way. Existing ontologies, such as the Gene Ontology and others in the Open (...) Biological and Biomedical Ontologies (OBO) Foundry library, provide a semantic structure but lack many of the necessary terms to describe biodiversity data in all its dimensions. In this paper, we describe the motivation for and ongoing development of a new Biological Collections Ontology, the Environment Ontology, and the Population and Community Ontology. These ontologies share the aim of improving data aggregation and integration across the biodiversity domain and can be used to describe physical samples and sampling processes (for example, collection, extraction, and preservation techniques), as well as biodiversity observations that involve no physical sampling. Together they encompass studies of: 1) individual organisms, including voucher specimens from ecological studies and museum specimens, 2) bulk or environmental samples (e.g., gut contents, soil, water) that include DNA, other molecules, and potentially many organisms, especially microbes, and 3) survey-based ecological observations. We discuss how these ontologies can be applied to biodiversity use cases that span genetic, organismal, and ecosystem levels of organization. We argue that if adopted as a standard and rigorously applied and enriched by the biodiversity community, these ontologies would significantly reduce barriers to data discovery, integration, and exchange among biodiversity resources and researchers.

If Mont Blanc is a vague object, then its vagueness will depend on the context in which reference is made. In a geological context the mountain might include only rock, perhaps together with a certain amount of air in the crevices and tunnels which have been formed beneath its surface. In a context of soil chemistry we might include also a surrounding thin layer of organic matter. In a skiing context we might include some snow. This essay sketches in informal (...) terms the theory of granular partitions, which is designed to do justice to this context-dependence of vagueness by means of what might be described as a contextualized supervaluationism. Granularity and vagueness, it is argued, are two sides of a single coin: what is vague at one level of granularity may appear crisp at another. The resultant theory can be shown to resolve certain problems in our description of perceptual content, for example when John says that he sees the wall, but that he does not see the molecules by which the wall is constituted.

Abstract -/- Quetico’s ecosystem functions as a dynamically emergent resonance system rather than a static equilibrium. Its biodiversity is governed by a complex interplay of interacting sub-resonances, including lichen, trees, fish, fungi, and hydrodynamic cycles. The traditional view of boreal ecology relies on linear succession models, which assume ecosystems transition from disturbance to stability in a predictable manner. Other models attempt to incorporate stochastic biodiversity fluctuations, treating species distributions as the outcome of probabilistic chance events. Both perspectives fail to recognize (...) the deeper chirality of dynamic emergent systems (CODES) that shape long-term ecological oscillations in Quetico. The landscape does not simply evolve in a stepwise progression or through random fluctuations but instead follows a structured resonance-driven framework, where species distributions, dominance cycles, and trophic hierarchies emerge from coherent phase interactions. -/- A new paradigm for boreal wilderness modeling emerges when each major biological and geophysical domain—fungal networks, aquatic ecosystems, arboreal succession, and trophic feedback loops—is analyzed as an interacting, phase-locked sub-resonance within Quetico’s larger asymmetric “heartbeat.” Unlike conventional models, which view climax forests or fish populations as endpoints of equilibrium, this perspective identifies them as temporary attractors within an ongoing oscillatory structure. -/- Four core principles define this asymmetric ecological resonance: 1. Tree succession follows non-random resonance oscillations. The interplay of lichen-fungal priming, mycorrhizal frequency-locking, and soil phase transitions determines which species take root and in what sequence. The composition of the forest is not a simple function of environmental opportunity but an emergent consequence of phase-coherent microbial and nutrient signaling. 2. Fish populations are not governed by chance fluctuations but by phase-locking with aquatic microbiota and hydrodynamic nutrient flows. This produces recursive cycles of dominance, where species such as walleye, lake trout, and northern pike oscillate in predictable, structured shifts rather than in stochastic booms and busts. 3. Lichen and fungi serve as ecological memory structures. Rather than acting as passive indicators of environmental conditions, they encode prior phase states, carrying the informational residue of past stability or collapse cycles that dictate the long-term equilibrium of forests and aquatic systems. 4. Quetico’s wilderness does not exist in a fixed state but as a multi-tiered resonant wave. Ecosystem stability is an illusion created by overlapping oscillatory cycles, where collapse and reorganization follow prime-frequency ecological structures. Forest regrowth, lake stratification, and biodiversity shifts are all chiral oscillations rather than linear progressions. -/- A structured resonance approach provides a coherent alternative to probability-driven ecological paradigms, shifting focus away from stochastic unpredictability and toward phase-locked predictability in ecological transitions. This framework has far-reaching implications for predictive ecosystem modeling, conservation optimization, and resilience engineering in boreal systems. By aligning conservation strategies with underlying resonance structures, it becomes possible to accelerate natural succession, mitigate biodiversity loss, and enhance ecosystem resilience without imposing artificial stability. The asymmetric heartbeat of Quetico is not merely a metaphor—it is a physical reality embedded within the structured emergence of its wilderness. (shrink)

plant watering and monitors crop health to enhance farming efficiency and sustainability. The first component of the system is an automatic plant watering system, which leverages soil moisture sensors to monitor real-time soil conditions. When the soil moisture level falls below a predefined threshold, the system triggers an automatic irrigation process via a water pump. This system can be remotely controlled and monitored through a smartphone application or web interface, ensuring optimal water usage and preventing over-watering or under-watering. The second (...) component, the crop health indicator, uses a combination of environmental sensors (temperature, humidity, soil pH, light intensity) and advanced imaging technologies such as multispectral cameras or drones to assess crop health. These sensors detect critical factors affecting plant growth and yield, such as disease, pest infestation, or nutrient deficiencies. The data collected from these sensors is processed in real-time and analyzed to provide actionable insights and timely alerts to farmers, enabling them to take appropriate actions to address crop stress and optimize yield. The system is designed to be user-friendly, providing farmers with easy access to critical data and control through mobile and web interfaces. The integration of these technologies aims to reduce resource consumption, enhance crop productivity, and support sustainable agricultural practices. (shrink)

Autonomous and automatic weapons would be fire and forget: you activate them, and they decide who, when and how to kill; or they kill at a later time a target you’ve selected earlier. Some argue that this sort of killing is always wrong. If killing is to be done, it should be done only under direct human control. (E.g., Mary Ellen O’Connell, Peter Asaro, Christof Heyns.) I argue that there are surprisingly many kinds of situation where this is false and (...) where the use of Automated Weapons Systems would in fact be morally required. These include cases where a) once one has activated a weapon expected then to behave lethally, it would be appropriate to let it continue because this is part of a plan whose goodness one was best positioned to evaluate before activating the weapon; b) one expects better long-term consequences from allowing it to continue; c) allowing it to continue would express a decision you made to be resolute, a decision that could not have advantaged you had it not been true that you would carry through with it; d) the weapon is mechanically not recallable, so that, to not allow it to carry through, you would have had to refrain from activating it in the first place, something you expected would have disastrous consequences; e) you must deputize necessary killings to autonomous machines in order to protect yourself from guilt you shouldn’t have to bear; f) it would be morally better for the burden of responsibility for the killing to be shared among several agents, and the agents deputizing killing to machines can do this, especially where it’s not predictable which machine will be successful; g) a killing would be morally better done with elements of randomness and lack of deliberation, and a (relatively stupid) machine could do this where a person could not; h) the machine would be acting as a Doomsday Device, so that it could not have had its hoped for deterrent effect had you not ensured that you would be unable to recall it if enemy action activated it; i) letting it carry through is a necessary part of its own learning process, and you expect that this learning will have salutary effects later on; j) human intervention in the machine’s operation would disastrously impair its precision, or its speed and efficiency; k) using non-automated methods would require human resources you just don’t have in a task that nevertheless must be done (e.g., using land-mines to protect remote installations); l) the weapon has such horrible and indiscriminate power that it is doubtful whether it could be actually used in ways compatible with International Humanitarian Law and the Laws of War, which require that weapons be used only in ways respecting distinctness, necessity and proportionality, but its threat of use could respect these principles in affording deterrence provided human error cannot lead to their accidental deployment, this requiring that they be controlled by carefully designed autonomous and automatic systems. I then consider objections based on conceptions of human dignity and find that very often dignity too is best served by autonomous machine killing. Examples include saving your village by activating a robot to kill invading enemies who would inflict great indignity on your village, using a suicide robot to save yourself from a less dignified death at enemy hands, using a robotic drone to kill someone otherwise not accessible in order to restore dignity to someone this person killed and to his family, and using a robot to kill someone who needs killing, but the killing of whom by a human executioner would soil the executioner’s dignity. I conclude that what matters in rightful killing isn’t necessarily that it be under the direct control of a human, but that it be under the control of morality; and that could sometimes require use of an autonomous or automated device. (This paper was formerly called "Fire and Forget: A Defense of the Use of Autonomous Weapons in War" on Philpapers; the current title is the title of the published version.). (shrink)

This study investigated the effectiveness of utilizing induced magnetism on the seed germination of radish (Raphanussativus) in terms of growth rate, growth speed, shoot growth, and overall development. This study utilized two groups that consisted of an experimental group where induced magnetism was present one control group where there was an absence of induced magnetism in the seed germination of Radish (Raphanus sativus). Moreover, this study aimed to determine the significant difference between the two in terms growth rate, growth speed, (...) shoot growth, and overall development. Both groups had the same amount of radish (Raphanus sativus) seeds planted in a rectangular wooden container with the same amount of measurement and soil content. This study used an experimental research design by utilizing the functions of an Electromagnetic Induction Device (EID) comprised of a 12v motor battery, light bulb, coiled wire, and switch. The EID was turned on for 10 minutes every day where the electric volts generated by the 12v motor battery were transported through the coiled wire and distributed to the metallic iron screen surrounding the area of the experimental group. The data gathered during the 12-day observation of the growth of radish (Raphanus sativus) were tabulated, analyzed, and evaluated using mean tests, standard deviation, and T-test. Based on the result and analyses of the gathered data, it was found that the experimental group, the one with the presence of induced magnetism, surpassed the control group in terms of growth speed, shoot growth, and overall seed development. However, it was also revealed that in terms of growth rate, there is no significant difference between the control group and experimental group. Therefore, the utilization of Induced Magnetism on the seed germination of radish (Raphanus sativus) is effective in terms of growth speed, shoot growth, and overall development. (shrink)

The growth response, metal tolerance and phytoaccumulation properties of water spinach (Ipomoea aquatica) and okra (Abelmoschus esculentus) were assessed under different contaminated spiked metals: control, 50 mg Pb/kg soil, 50 mg Zn/kg soil and 50 mg Cu/kg soil. The availability of Pb, Zn and Cu metals in both soil and plants were detected using flame atomic absorption spectrometry. The concentration and accumulation of heavy metals from soil to roots and shoots (edible parts) were evaluated in terms of translocation factor, accumulation (...) factor and tolerance index. Okra recorded the highest accumulation of Pb (80.20 mg/kg) in its root followed by Zn in roots (35.70 mg/kg) and shoots (34.80 mg/kg) of water spinach, respectively. Different accumulation trends were observed with, Pb > Zn > Cu in okra and Zn > Pb > Cu in water spinach. Significant differences (p < 0.01) of Pb, Zn and Cu accumulation were found in both water spinach and okra cultivated among tested treatments. However, only the accumulation of Pb metal in the shoots of water spinach and okra exceeded the maximum permissible levels of the national Malaysian Food Act 1983 and Food Regulations 1985 ([2006]) as well as the international Codex Alimentarius Commission limits. This study has shown that both water spinach and okra have good potential as Pb and Zn phytoremediators. (shrink)

The story of eternity is not as simple as a secularization narrative implies. Instead it follows something like the trajectory of reversal in Kant’s practical proof for the existence of god. In that proof, god emerges not as an object of theoretical investigation, but as a postulate required by our practical engagement with the world; so, similarly, the eternal is not just secularized out of existence, but becomes understood as an entailment of, and somehow imbricated in, the conditions of our (...) practical existence. -/- The sections that follow discuss some of those central figures in modern European philosophy whose views prominently feature some consideration of eternity. I start with Kant in section I. Kant’s critique of speculative theology is well-known, and this hostility would appear to make it unlikely that the eternal, with all its theological baggage, would feature prominently in Kant’s critical philosophy. But in fact Kant’s transcendental idealism endorses no fewer than three different concepts of the eternal, including what turns out to be the most historically influential idea: that practical reason involves a kind of eternal, non-temporal action. Kant shifts this notion of a non-temporal act from its original theological context of god’s actus purus to a practical context, setting the stage for Schelling’s and Kierkegaard’s later development of this theme. Before detailing this trajectory however, section II is devoted to Hegel, the philosopher whose radical historicism is perhaps more than any other thinker responsible for making “the nineteenth century preeminently the historical century.”4 Hegel is not fertile soil for the concept of the eternal, but his historicism does turn out, at a crucial moment in the philosophy of nature, to presuppose a certain conception of eternity as an eternal present. Perhaps more importantly for the further development of eternity in nineteenth century thought however is that both Schelling and Kierkegaard situate their views of the eternal in the context of a collective rejection of Hegel. Section III discusses Schelling, who returns to Kant’s conception of non-temporal choice, seeing human capacities for free eternal self-creation as rivaling god’s. Such powers are required, Schelling argues, to resist the sublimation of the individual human person into the blankness of the Absolute. Section IV briefly consider Schopenhauer’s view that the in-itself of everything is an endlessly striving will. Section V concerns Kierkegaard who is strongly committed to the eternal, and indeed criticizes Hegel for compromising his conception of the eternal by thinking it temporally; but he is obsessed by the paradoxical question of our practical “access” to the eternal within a particular temporal moment: the decisive moment, imbued with significance that can turn life around and create a new person, pushing Schelling’s concerns even further. The remaining, shorter sections, present briefer accounts of more recent figures who make important use of some conception of the eternal: Nietzsche’s eternal return (section VI), Agamben’s (1942-) theory of sovereignty (section VII) and finally Alain Badiou’s unapologetic attempt to resuscitate eternity as the condition of revolutionary political change (Section VIII). I end with a concluding meditation (Section IX). (shrink)

Abstract -/- -/- Current climate models rely on probability-driven emissions tracking and mitigation strategies, which fail to account for the structured resonance dynamics of planetary systems. CODES introduces a structured resonance-based framework that reinterprets environmental stability as a function of phase-locked coherence rather than stochastic fluctuations. -/- -/- This model posits that climate instability arises from resonance disruptions across atmospheric, biological, and energy systems, rather than isolated excesses of carbon or pollutants. Instead of treating emissions as independent variables, CODES reformulates (...) them as phase misalignments within a planetary-scale resonance system. -/- -/- Key insights include: -/- 1. Fossil fuel combustion disrupts structured thermal resonance, not just greenhouse gas levels. -/- 2. Industrial agriculture breaks microbial phase-locking cycles, accelerating soil entropy rather than just releasing CO₂. -/- 3. Plastic waste interferes with biological oscillatory coherence, altering cellular and ecological resonance patterns. -/- 4. Energy grids introduce chaotic frequency imbalances, amplifying entropy loss instead of optimizing power distribution. -/- 5. Urbanization follows inefficient non-fractal growth patterns, disrupting local environmental phase-locking. -/- -/- CODES reformulates these challenges through deterministic resonance corrections, replacing traditional mitigation strategies with phase-locking restoration methods. This includes: -/- • Resonance-driven energy storage and distribution systems that eliminate phase loss. -/- • Phase-matched carbon reintegration processes that restore planetary thermal equilibrium. -/- • Fibonacci-based agricultural restructuring to phase-lock soil and microbial dynamics. -/- • Resonance-aligned biomaterials that self-degrade in structured time intervals. -/- • Fractal-driven urban expansion models that prevent environmental overload and instability. -/- -/- By aligning climate solutions with structured emergence rather than probability-based interventions, CODES provides a coherence-driven framework for planetary restoration—one that does not resist entropy but guides it back into structured equilibrium.

Achieving sustainability in agriculture requires more than just individual actions—it demands a fundamental shift toward environmental responsibility. Historically, destructive agricultural practices such as intensive monoculture and excessive tillage have led to severe soil degradation, threatening the long-term sustainability of food production. Joseph Russell Smith’s early advocacy for “tree crops” highlighted the profound benefits of incorporating trees into farming systems, emphasizing their role in restoring ecological balance and preserving soil integrity. Although Smith’s vision was articulated a century ago, it remains highly (...) relevant today, with agroforestry emerging as a particularly effective approach to sustainable agriculture. (shrink)
