Impact of Cropping Methods on Biodiversity in Coffee Agroecosystems in Sumatra, Indonesia 7

The sustainable management of biodiversity and productivity in forested lands requires an understanding of key interactions between socioeconomic and biophysical factors and their response to environmental change. Appropriate baseline data are rarely available. As part of a broader study on biodiversity and profitability, we examined the impact of different cropping methods on biodiversity (plant species richness) along a subjectively determined land-use intensity gradient in southern Sumatra, ranging from primary and secondary forest to coffee-farming systems (simple, complex, with and without shade crops) and smallholder coffee plantings, at increasing levels of intensity. We used 24 (40 x 5 m) plots to record site physical data, including soil nutrients...

Integrated land use modelling of agri-environmental measures to maintain biodiversity at landscape level 31
Schonhart, Martin; Schauppenlehner, Thomas; Schmid, Erwin.
Integrated land use models (ILM) are increasingly applied tools for the joint assessment of complex economic-environmental farming system interactions. We present an ILM that consists of the crop rotation model CropRota, the bio-physical process model EPIC, and the farm optimization model FAMOS[space]. The ILM is applied to analyze agri-environmental measures to maintain biodiversity in an Austrian landscape. We jointly consider the biodiversity effects of land use intensity (i.e. nitrogen application rates and mowing frequencies) and landscape development (e.g. provision of landscape elements) using a rich indicator set and region specific species-area relationships. The cost-effectiveness of agri-environmental measures in attaining alternative...
