东非国家由于不可预测的降雨不足而陷入严重的水压力。气候变化的影响使降雨变异性的影响更加复杂,气候变化进一步加剧了该地区有限的气候耐水水基础设施。这些因素可能会导致对人类和农业需求以及牲畜的安全和充足水的可用性和可及性大幅降低,这阻碍了非洲之鹰的经济增长和可持续发展。While, on the one side, there is potential for better management and use of the available water, specially in degraded and abandoned agricultural lands (i.e., the so called "marginal lands"), on the other side, change in land use may increase pressure on ecosystem services and on communal/informal/traditional non-intensive customary livelihood activities in the marginal lands, and in some cases even exacerbate water scarcity and粮食不安全。
