"Carbon stocks in tropical agroforestry systems in the Alto Beni (Bolivia)"
Conversion of tropical and subtropical ecosystems into cropland and pastures is still triggering loss of biodiversity and contributes significantly to increases in atmospheric greenhouse gas (GHG) concentrations. Furthermore, unsustainable use of the land leads to soil degradation and associated socioeconomically problems. The fertility of soil is important for plant growth and essential for local food production. To preserve soil fertility and to secure livelihood adapted land use is unavoidable.
One possibility for adapted land use is the use and the development of sustainable (economic and ecological) agro-ecosystems. Especially for rural small scale farmers agroforestry systems with low external inputs are viable alternatives.
The purpose of the proposed study is to estimate the carbon stocks, nutrient and carbon fluxes and the mineralization of leaf litter of different cocoa-cropping systems with field and laboratory experiments. The aim is to quantify the potential of organic cocoa production to preserve soil fertility and to store carbon in soil and phytomass. The project is located in the Alto Beni region Bolivia, where cocoa trees are native and organic cocoa cultivation has a long tradition.
The Long-term farming trial in Bolivia has been established by the Research Institute of Organic Agriculture (FiBL) to test the performance of cash crop cultivation under organic agroforestry practices in tropical lowland regions
