Thirsty and hungry cities are posing significant challenges for the urban-rural interface ranging from food security to inter-sectoral water allocation. Not only is the supply of resources to urban centres a growing challenge in low-income countries, but even more is the urban return flow, as investments in waste management and sanitation, ie the ‘ultimate food waste’, are not able to keep pace with population growth. And where polluted water is used in irrigation to feed the cities, food safety is becoming a crucial component of food security.

Large-scale agricultural land investments in Africa are often considered solely from the land perspective. Yet land, water and other natural resources are closely interlinked in agricultural production and in sustaining rural livelihoods. Such investments involving irrigation will potentially have implications for water availability and utilization by other users, making it imperative to regard water as an economic rather than a free good.

This study is part of a larger study on dairy marketing in Ethiopia, and concentrates on the producers'end of the marketing chain. Specifically, the markets of first sale used by dairy producers were identified and the marketing patterns of three categories of dairy producers (intra-urban, peri-urban and peasant) were investigated. The study was carried out on a sample of 173 dairy producers between February and July 1986, using structured questionnaires.

Given their substantial societal benefits, such as supporting economic activities and providing better livelihoods in rural areas, ecosystem services should gain higher importance in water-food-energy nexus debates. Yet, not all values from ecosystems are quantifiable, data is often not adequate and methods of measuring these values are not sound. This situation challenges researchers and water managers to improve research tools and give adequate attention to ecosystem services by implementing interdisciplinary approaches and integrated management of ecosystems and their services.

Safe emptying and disposal of fecal sludge from pit latrines in rural areas has become a priority for the Government of Bangladesh. In this paper, we calculate the volume and characterize the hazards of managing sludge to identify technologies for safely emptying rural single pits. In Bhaluka subdistrict, an estimated 15,000 m3 of sludge is produced annually. Physical, chemical, and microbial analysis of samples of sludge taken from pit latrines indicate that the sludge has a high moisture content of around 90%, a C:N ration of 10:1, and a helminth presence of 41 eggs/g.

Financial cooperatives and microfinance institutions (MFIs) are the two major sources of rural finance in Ethiopia. Whereas MFIs are relatively new, financial cooperatives have existed for centuries in various forms. The coexistence of two different institutions serving the same group of people, and delivering the same financial services, raises several policy questions. Those questions have become particularly relevant, as the government has embarked on developing a new strategy for improving rural financial services delivery.

This paper focuses on the application of the concept of Integrated Water Resources Management (IWRM) in Tanzania. It asks: how did IWRM affect the rural and fast-growing majority of smallholder farmers' access to water which contributes directly to poverty alleviation and employment creation in a country where poverty and joblessness are high?

The field for application of biomass is rising. The demand for food and feeding stuff rises while at the same time energy, chemicals and other materials also need to be produced from biomass because of decreasing fossil resources. However, the biorefinery ideas and concepts can help to use the limited renewable raw materials more efficiently than today. With biorefineries, valuable products, such as platform chemicals, can be produced from agricultural feedstock, which can subsequently be further processed into a variety of substances by the chemical industry.
