Sustainable land management strategies for the southern Amazon, Brazil, in the light of socio-economic aspects, plant diseases and climate change
The Southern Amazon in Brazil is one of world´s main production regions for agricultural commodities and at the same time a hotspot of tropical deforestation. The thesis aims to develop sustainable land management strategies to ease the conflict between human activities and nature in this sensitive ecosystem. In a simulation study, the biophysical and socio-economic dimension of yield gaps (difference between potential yield and actual yield) was identified. Furthermore, a plant protection application was used to study the spread of pests and plant diseases. Furthermore, the impact of climate change and technological progress on future yields was projected. The thesis shows that improved water and nutrient management, a reduction of socio-economic constraints, early plant disease detection and climate-resilient cultivation systems can result in a sustainable intensification of areas previously cleared. At the same time, more effective control mechanisms are needed to prevent the further expansion of pasture and arable land into the rainforest, as the importance of the Southern Amazon for the global climate and biodiversity stands in extreme contrast to its low agricultural potential.
