Green water is the water that is used in biomass production, and if well conserved this water can boost agricultural production. Drylands experience erratic rainfalls, poor soils and high rates of evapotranspiration. This situation has been made worse by climate variability as drylands are very sensitive to climate change due to their delicate nature. The effect of climate change in ASALs has resulted in poor agricultural production hence loss of livelihoods. Good management of green water during the rainy season can greatly increase agricultural production thus improving livelihoods. This research paper investigated the biophysical and socioeconomic factors that influence green water management with a focus on Kyawango sub-catchment. Data collection was collected through focus group discussions, key informant interviews, observation study, and household questionnaires. The household survey was carried out in 147 households which was the target population for the research location. The results revealed that management of the green water is determined by biophysical factors such as rainfall, soil type and socioeconomic factors such as demographic and, governance. The researcher further suggests strategies of encouraging communities to conserve green water for increased agricultural production and improved livelihoods.
Key words: Climate variability, ecosystem services on farm, diversification.
