Agricultural land investments and water management in the office du Niger, Mali: options for improved water pricing

Journal Articles & Books
Diciembre, 2016

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.

Business models for fecal sludge management

Reports & Research
Diciembre, 2016

On-site sanitation systems, such as septic tanks and pit latrines, are the predominant feature across rural and urban areas in most developing countries. However, their management is one of the most neglected sanitation challenges. While under the Millennium Development Goals (MDGs), the set-up of toilet systems received the most attention, business models for the sanitation service chain, including pit desludging, sludge transport, treatment and disposal or resource recovery, are only emerging.

Cultivating the desert: irrigation expansion and groundwater abstraction in northern state, Sudan

Journal Articles & Books
Diciembre, 2016

This study examines the socioeconomic features that underpin the expansion of groundwater-dependent irrigation in Northern State, Sudan. Groundwater development in the region serves as an economic lifeline given the poor Nile-based irrigation infrastructure and future changes in Nile hydrology. Groundwater-dependent irrigation is found to be expanding in previously uncultivated regions increasingly distant from the Nile.

Emergence, interpretations and translations of IWRM [Integrated Water Resources Management] in South Africa

Sudáfrica

South Africa is often regarded to be at the forefront of water reform, based on Integrated Water Resources Management (IWRM) ideas. This paper explores how the idea of IWRM emerged in South Africa, its key debates and interpretations and how it has been translated. It maps out the history, main events, key people, and implementation efforts through a combination of reviews of available documents and in-depth semi-structured interviews with key actors.

Evaluating the flow regulating effects of ecosystems in the Mekong and Volta river basins

Reports & Research
Diciembre, 2016

By altering evapotranspiration and influencing how water is routed and stored in a basin, natural and agrarian ecosystems affect river flow. To quantify the impact of ecosystems on streamflow in two large river basins in Asia and Africa, simple statistical relationships were calculated, enabling flow characteristics to be ascertained from basic catchment features. This approach allows the impact of specified land-use change on streamflow to be determined.

Experiences from stakeholder dialogues in Tamale, northern Ghana

Journal Articles & Books

Ghana

Tamale is the capital city of Ghana’s Northern Region. As the regional capital, Tamale is growing rapidly – the population has almost tripled to over 370,000 in the past 30 years, and the areal extent has increased up to sevenfold in the same period. Urban agriculture is an integral part of the food system, linked to resource management and spatial planning. In general one can say that backyard farming flourishes, but more formally organised production is threatened by urbanisation.

Geological and geomorphological controls on groundwater occurrence in a hard rock region

Journal Articles & Books
Diciembre, 2016

Remote sensing and GIS tools have broadly helped hydrogeologists to delineate the groundwater prospective zones for watershed development and management. The origin, movement and existence of groundwater depends on several factors such as slope, drainage density, land use, geology, lineament density and geomorphology. Based on these, the mapping and identification of groundwater potential zones were carried out in a part of Nalgonda district, Telangana, India.
