In a time of transition from subsistence to commercial agriculture, small farming households need to be better organized in order to match the market demand in terms of product volume and quality. However, spontaneous initiatives are often discouraged by the lack of proper support in terms of cre...

Swidden agriculture is often deemed responsible for deforestation and forest degradation in tropical regions, yet swidden landscapes are commonly not visible on land cover/use maps, making it difficult to prove this assertion. For a future REDD+ scheme, the correct identification of deforestation...

Geographic modelers frequently compare maps of observed land transitions to maps of simulated land transitions to relate the patterns in reference maps to the output from a simulation model. Pixel-by-pixel analysis of raster maps at a single resolution is useful for this task at a single scale, b...
