Summary We use case studies from Zimbabwe to illustrate the complexities that can undermine development efforts in semi-arid mixed farming areas. Livelihood improvement and micro-catchment management were considered in the context of portfolios of ho

Measurements of tree canopy architecture were made at six savanna sites on deep, sandy soils, along a gradient of increasing aridity. There was substantial variation in the leaf area estimated within each site, using the same sample frame, but differ
