Water scarcity threatens food security, public health and economic development in Africa. Lack of coordination and cooperation between actors in the water ecosystem drives scarcity and threatens use and management of the shared resource. Access to relevant information that facilitates awareness of water scarcity risks over familiar geographic scales is an important first step to addressing this challenge. In this paper, we describe the development of communitylevel water scarcity risk estimates along with the initial architecture of the proposed system for estimating these risks. Copyright 2014 ACM.
