The absence of a national soilclassification system for Nigeria hinderssuccessful agrotechnology transfer inparticular, and agricultural development ingeneral. A discussion of the role of indigenousknowledge in agricultural development showsthat indigenous knowledge of the soil can beintegrated with modern soil science to developa soil classification system for the country.Much as local knowledge is invaluable foradvancing scientific knowledge and vice versa,caution is given against overestimating therole of indigenous knowledge in developmentalactivities. It is important to encourage theproper integration of all knowledge systems increating new (...) paradigms for sustainabledevelopment in Nigeria. (shrink)

Ugandan smallholder farmers need to feed a growing population, but their efforts are hampered by declining soil fertility rates. Agricultural extension can facilitate farmers’ access to new practices and technologies, yet farmers are understandably often hesitant to adopt new behaviors. New knowledge assimilation is an important component of behavior change that is often overlooked or poorly addressed by current extension efforts. We implemented a Fertility Management Education Program in central Uganda to investigate smallholder farmers’ existing soil knowledge and their assimilation (...) of new scientific concepts into their knowledge framework. Qualitative data were collected through participant observation, farmer interviews, and focus groups, and coded for using a priori and emergent themes. Our exploration revealed some notable similarities between farmers’ soil knowledge and scientific concepts, particularly in regards to soil health concepts, a discovery that could facilitate communication between extension agents and farmers. However, certain scientific concepts are either unknown to farmers or discordant with existing soil knowledge; these concepts are unlikely to be assimilated by farmers without convincing and concerted extension efforts. Importantly, we found that the combination of new scientific knowledge and hands-on experimentation with novel practices gave farmers far greater confidence in implementing improved soil management practices. Our study provides evidence that extension programs should engage directly with farmers’ existing soil knowledge to develop their understanding of key biological concepts and confidence in implementing improved practices.

The failure to properly account forthe total value of environmental and natural resourcesresults in socially undesirable overexploitation anddegradation of complex ecosystems such as mangrovewetlands. However, most ecosystem valuation researchtoo often focuses on the question of “what is the value” and not enough on “what peoplevalue.” Nonmarket valuation practitioners have usedqualitative approaches in their work for some time.Yet, the relative strengths and weaknesses ofdifferent qualitative methods have been more thesubject of speculation than systematic research. Thestatistical examination of focus group and individualinterview (...) data on ecosystem services illustrates thatthe two methods generate important but differentecosystem service data. Further, the data show thatthe use of multiple data collection methods offers amore robust understanding of what people value. (shrink)
