16. Influence of soil amendments and soil properties on macro– and micronutrient availability to microorganisms and plants
Sammanfattning : Utilising by-products from industrial and domestic activities and from bioenergy production is one of the new ways of recovering and re-using nutrient resources in agriculture. However, these by-products can potentially add toxic elements or alter soil properties in ways that harm the soil and related environments. LÄS MER
17. European ecosystems on a changing planet : Integrating climate change and land-use intensity data
Sammanfattning : Dynamic global vegetation models are mathematical models that provide a bottom-up description of plant communities. They explicitly model physiological and population-level processes such as growth, photosynthesis, carbon allocation, regeneration and mortality. LÄS MER
18. Revisiting push-pull technology: Below and aboveground mechanisms for ecosystem services
Sammanfattning : Push-pull technology is an effective and ecological solution to suppressing major Lepidopteran pests of cereals, in particular stem-borers (Busseola fusca, Chilo partellus), the fall armyworm (Spodoptera frugiperda) and the parasitic weed Striga. The technology exploits plant-insect interactions in intercropping practices to manage the pests, increasing productivity while maintaining ecosystem resilience. LÄS MER
19. Barriers and bridges for introducing agroforestry and community-based forestry among food insecure households in eastern Africa
Sammanfattning : The aim of introducing agroforestry and community-based forestry is to secure and improve livelihoods, maintain and restore ecosystem services, and contribute to climate change mitigation and adaptation. However, the adoption and scaling up of these systems among food insecure communities have proved to be difficult. LÄS MER
20. Restoration of plant and pollinator communities in fragmented grasslands
Sammanfattning : A large proportion of the former area of species-rich semi-natural grasslands has been lost due to agricultural intensification and abandonment. Remaining small and isolated grassland fragments are often imbedded in more or less intensively managed landscapes. LÄS MER
