Technological interventions to address the problem of poor productivity of smallholder agricultural systems must be designed to target socially diverse and spatially heterogeneous farms and farming systems. This paper proposes a categorisation of household diversity based on a functional typology...

The diversity of rural livelihoods and their influence on soil fertility in agricultural systems of East Africa – A typology of smallholder farms
Heterogeneity in soil fertility in these smallholder systems is caused by both inherent soil-landscape and human-induced variability across farms differing in resources and practices. Interventions to address the problem of poor soil fertility in Africa must be designed to target such diversity a...

Soil Heterogeneity and Soil Fertility Gradients in Smallholder Agricultural Systems of the East African Highlands
Analysis of head capsule widths of banana weevil larvae was carried out to determine the number and recognition of instars. The analysis involved model fitting to frequency distributions of head capsule measurements of laboratory-reared and field-collected larvae. The laboratory population reveal...
