Improvement of sanitation facilities and subsequent practices is considered to contribute to overall human development with far reaching benefits for the welfare of people. It can reduce wastewater flows when treatment capacities are upgraded, but it can also create a higher load of wastewater flowing into the environment downstream. Additional sanitary water requirements in a water scarce city may be difficult to meet. In this paper we explore the scale of impact of improving sanitation in Addis Ababa in terms of water quality and quantity of water flows in and out of the city. Conventional approaches to sanitary improvement at the city level, like extension of the sewage coverage and upgrading of wastewater treatment capacities will require additional water in a city that is already water scarce. Also, it will change the characteristics of irrigation water that is used by farmers in and around the city.

A recent study of the livestock water productivity (LWP), at higher spatial scales in the Blue Nile Basin, indicated strong variability across regions. To get an insight into the causes of this variability, we examined the effect of farm households’ access to productive resources (e.g. land, livestock) on LWPin potato–barley, barley–wheat, teff–millet and rice farming systems of the Gumera watershed (in the Blue Nile Basin, Ethiopia). We randomly selected 180 farm households. The sizes of the samples, in each system, were proportional to the respective system’s area. Then we grouped the samples, using a participatory wealth ranking method, into three wealth groups (rich, medium and poor) and used structured and pretested questionnaires to collect data on crops and livestock management and applied reference evapotranspiration (ET0) and crop coefficient (Kc) approaches to estimate depleted (evapotranspiration) water in producing animal feed and food crops. Then, we estimated LWPas a ratio of livestock’s beneficial outputs to water depleted. Our results suggest strong variability of LWP across the different systems: ranging between 0.3 and 0.6 US$ m3 year1. The tendency across different farming systems was comparable with results from previous studies at higher spatial scales. The range among different wealth groups was wider (0.1 to 0.6 US$ m3 year1) than among the farming systems. This implies that aggregating water productivity (to a system scale) masks hotspots and bright spots. Our result also revealed a positive trend between water productivity (LWPand crop water productivity, CWP) and farm households’ access to resources. Thus, we discuss our findings in relation to poverty alleviation and integrated land and water management to combat unsustainable water management practices in the Blue Nile Basin.

Water is essential for agriculture including livestock. Given increasing global concern that access to agricultural water will constrain food production and that livestock production uses and degrades too much water, there is compelling need for better understanding of the nature of livestock–water interactions. Inappropriate animal management along with poor cropping practices often contributes to widespread and severe depletion, degradation and contamination of water. In developed countries, diverse environmental organisations increasingly voice concerns that animal production is a major cause of land and water degradation. Thus, they call for reduced animal production. Such views generally fail to consider their context, applicability and implications for developing countries. Two global research programs, the CGIAR ‘Comprehensive Assessment of Water Management and Agriculture’ and ‘Challenge Program on Water and Food’ have undertaken studies of the development, management and conservation of agricultural water in developing countries. Drawing on these programs, this paper describes a framework to systematically identify key livestock–water interactions and suggests strategies for improving livestock and water management especially in the mixed crop–livestock production systems of sub-Saharan Africa. In contrast to developed country experience, this research suggests that currently livestock water productivity compares favourably with crop water productivity in Africa. Yet, great opportunities remain to further reduce domestic animals’ use of water in the continent. Integrating livestock and water planning, development and management has the potential to help reduce poverty, increase food production and reduce pressure on the environment including scarce water resources. Four strategies involving technology, policy and institutional interventions can help achieve this. They are choosing feeds that require relatively little water, conserving water resources through better animal and land management, applying well known tools from the animal sciences to increase animal production, and strategic temporal and spatial provisioning of drinking water. Achieving integrated livestock- water development will require new ways of thinking about, and managing, water by water- and animal-science professionals.
