This case study explores the different barriers that men and women face when implementing sustainable land management (SLM) under the Nairobi Water Fund (NWF) in Kenya. The NWF is a public-private partnership, designed by The Nature
Conservancy (TNC) as a payment for ecosystem services (PES) scheme, under which farmers in the Upper Tana River basin receive in-kind payments for implementing sustainable land management practices. They include constructing water pans -

This analysis of global and Asian markets looks at protectionism and substitution (decline in starch trade, rise in trade of cassava feedstuffs) and the Asian regional market for cassava feedstuffs. The degree of substitution between cassava and grains has increased measurably during the postwar period. Cassava's future in world markets depends on its ability to compete with grains; so far this has depended on grain pricing policies and tariff structures of importing countries, making cassava trade more vulnerable than the international grain trade.

A study was conducted to identify the most productive cultivars and their cutting management to optimize nutrient productivity in semi-arid areas of Rwanda. Four cultivars of Brachiaria brizantha (Piatá, MG4, Marandú and Xaraes), two cultivars of Brachiaria humidicola (Llanero and Humidicola), two cultivars of Brachiaria hybrid (Mulato and Mulato II) and one cultivar of Brachiaria decumbens (Basilisk) were evaluated against Napier grass (Pennisetum purpureum) in an on-farm trial in a complete randomised block design with four replicates.

This study aims to explain effects of soil textural class, topography, land use, and land use history on soil greenhouse gas (GHG) fluxes in the Lake Victoria region. We measured GHG fluxes from intact soil cores collected in Rakai, Uganda, an area characterized by low‐input smallholder (<2 ha) farming systems, typical for the East African highlands. The soil cores were air dried and rewetted to water holding capacities (WHCs) of 30, 55, and 80%. Soil CO2, CH4, and N2O fluxes were measured for 48 h following rewetting.
