África oriental

Extending livestock grazing to the steep slopes has led to unstable grazing systems in the East African Highlands, and new solutions and approaches are needed to ameliorate the current situation. This work was aimed at studying the effect of livestock grazing on plant attributes and hydrological properties. The study was conducted from 1996 to 2000 at the International Livestock Research Institute at Debre Ziet Research Station. Two sites were selected: one at 0-4% slope, and the other at 4-8% slope.

Data on water sources, mode of offer, watering frequency, amount of water offered, body weights and milk yield were collected from 21 randomly selected smallholder farms in Kiambu by means of farm visits and questionnaires fortnightly. Most farms (67%) had water on-farm but 76% of them needed labour to deliver the water to the animals. Fifty two percent of the farms practised continuous watering. Water troughs (67%) were mostly used to water dairy cattle.

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.

Empowering communities to manage natural resources: case studies from Southern Africa

Journal Articles & Books
Diciembre, 2000

This report consists of a series of individual country papers prepared for a study on devolution, community empowerment and power relations in community-based natural resource management (CBNRM) in the SADC region. Case studies were undertaken during 1999 in eight southeastern/eastern African countries; Botswana, Lesotho, Malawi, Namibia, Zambia, Zimbabwe, South Africa (two separate studies) and Tanzania. These studies drew mainly on existing literature and the direct experiences of authors in CBNRM initiatives in their own countries.

El papel de las instituciones informales en el uso de los recursos forestales en América Latina

Bolivia
Brasil
Guatemala
Nicaragua

This study adopts an institutional approach to analyze the way in which informal rules, in their interaction with formal rules, shape the use of forest resources by diverse types of smallholders and communities (i.e., indigenous people, agro-extractive and traditional communities) in Latin America. Attention is given to understanding the ‘working rules’, comprising both formal and informal rules, that individuals use in making their decisions for land and forest resources access and use, which in turn affect benefits generation and distribution from such resources use.

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.

Le projet « WISE UP to climate » vise a demontrer l'utilite des infrastructures naturelles comme une « solution basee sur la nature » pour l'adaptation au changement climatique et le developpement durable. Dans le bassin de la Volta, les infrastructures naturelles, comme les construites, offrent des benefices pour la subsistance des personnes. Comprendre les interrelations entre ces deux types d'infrastructures est une condition indispensable a une gestion et un developpement durables des ressources en eau.

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.
