1. In the wake of the Green Revolution : Environmental and socioeconomic consequences of intensive rice agriculture - The Problems of weeds in Muda, Malaysia
Sammanfattning : The agricultural intensification strategies represented by the Green Revolution have since the mid-1960s had a very positive impact on food-grain production in Asia. Presently, however, a post-Green Revolution phase of declining growth in output and productivity is experienced in many of the areas where intensification took place. LÄS MER
2. Strategic nitrogen management in stockless organic cropping systems : redistribution of residual biomass for improved energy and nitrogen balance
Sammanfattning : A griculture faces the challenge of producing high yields to feed a growing world population, while simultaneously addressing environmental problems such as eutrophication, emissions of greenhouse gases, loss of biodiversity and soil degradation. Organic farming can be part of the solution, as it promotes biodiversity, uses less energy for fertiliser production and often has higher inputs of organic matter to soil than conventional farming.

4. "At Least There is Something!" : Strategic decision-making by female farmers in Western Kenya
Sammanfattning : In rural sub-Saharan Africa women are often described as the most important farmers, producing the bulk of subsistence food. In this study it is shown that female farmers in the four visited villages of Western Kenya are much more than farmers. LÄS MER
5. Insect pollination of oilseed rape
Sammanfattning : Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. LÄS MER
