Climate-Smart Agriculture in Ethiopia

The agriculture sector is the backbone of Ethiopia’s economy and livelihoods. Yet, heavy reliance on rain-fed systems has made the sector particularly vulnerable to variability in rainfall and temperature. Climate change may decrease national gross domestic product (GDP) by 8–10% by 2050, but adaptation action in agriculture could cut climate shock-related losses by half. • Climate risk management interventions and long-term adaptation actions need to match localized vulnerabilities and impacts.

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.

Nuestra especie entró en grupos pequeños al continente americano a través de Beringia hace 20-15 000 años. Compartió con Siberia Oriental el chamanismo y con él la búsqueda de plantas y hongos alucinógenos y, como consecuencia, el conocimiento detallado de la flora y el continuo interés por experimentar. Al entrar en el interior del continente americano, nuestra especie contribuyó –por la caza continua– a la extinción de su megafauna.
