A new hypothesis for the functional role of diversity in mediating resource pools and weed-crop competition in agroecosystems
(Oxford, UK: Wiley-Blackwell, 2010)
We develop a new conceptual model we call the Resource Pool Diversity Hypothesis (RPDH) aimed at explaining how soil resource pool diversity may mediate competition for soil resources between weeds and crops. The primary ...
Impacts of pesticide use on cashew yield and farmers’ health cost: A case study in Nghia Trung commune, Binh Phuoc province
In Vietnam, cashew is a critical perennial crop. Attempts at its commodification has led to increased use of pesticides and inorganic fertilizers. The purpose of the study was to determine the outcomes of pesticide use ...
Adding value to field-based agronomic research through climate risk assessment: A case study of maize production in Kitale, Kenya
(Cambridge University Press, 2010)
Rainfed agriculture is the primary source of food production in sub-Saharan Africa (SSA). Recommendations for agricultural practices in the area are based upon agronomic crop research. However the research may not have ...
Conservation agriculture effects and policy support to mitigate soil degradation in Midi-Pyrénées (France)
(John Wiley & Sons, Ltd, 2010)
According to a soil risk assessment that evaluated European soils in 2005, approximately 25% of European land is at some risk of erosion. Degraded soil reduces the soil's ability to absorb water and replenish groundwater ...
Making sense of 21st century climate change in the Altiplano: Observed trends and CMIP3 projections
(Taylor & Francis, LLC., 2010)
This research presents a synthesis of the first phase of regionalizing climate projections for
CMIP3 projected changes in the annual cycle of the South American monsoon
A warmer world will spur many changes in weather patterns and ecosystems. It is critical to predict these changes in order to mitigate their potential negative impacts. The South American monsoon is vulnerable to these ...
Experiences in integrated management of natural resources in the sub-watershed of the Chimbo River, Ecuador
(St. Joseph, MI: American Society of Agricultural and Biological Engineers, 2010)
As is typical of many rural areas in developing countries, the Andean region of Ecuador is characterized by extreme poverty, owing to low agricultural productivity, limited human skills in business management and implementation ...
Managing grazing animals to achieve nutrient cycling and soil improvement in no-till integrated systems
(Springer Netherlands, 2010)
Long-term consequences of unsustainable intensification of agriculture are beginning to emerge and cause environmental issues in the world today. Integrating livestock into no-till systems has been shown to increase ...
