11. Ecology and management of crop pollination and pest control : insights from red clover seed production
Sammanfattning : The agricultural landscape has gone through large changes to meet increasing demands for food. This has led to major biodiversity declines, while effects on ecosystem services that support agricultural productivity, such as pollination and pest control, remain less studied. LÄS MER
12. 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. LÄS MER
13. Sustainable Land and Water Management for a Greener Future : Large-scale insights in support of Agroecological Intensification
Sammanfattning : The challenge of producing more food in times of climate change, degraded land and scares water resources is calling for a radical transformation of agriculture. Sustainable agricultural intensification is the process of increasing the productivity of farms while preserving functional ecosystems. LÄS MER

15. Diversifying crop rotations for sustainable production and climate change adaptation
Sammanfattning : Industrial cropping systems are increasingly simplified, with fewer crops being grown, requiring extensive use of inputs, and contributing to environmental pollution and climate change. Solutions are needed to reduce the negative effects, while retaining productivity in the face of increasingly frequent detrimental climatic conditions. LÄS MER
