Typology of irrigation systems in Ghana.

Abstract

I n t e r n a t i o n a l Water Management I n s t i t u t e years IWMI Celebrating Working PapersThe publications in this series record the work and thinking of IWMI researchers, and knowledge that the Institute's scientific management feels is worthy of documenting. This series will ensure that scientific data and other information gathered or prepared as a part of the research work of the Institute are recorded and referenced. Working Papers could include project reports, case studies, conference or workshop proceedings, discussion papers or reports on progress of research, country-specific research reports, monographs, etc. Working Papers may be copublished, by IWMI and partner organizations.Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible all data and analyses will be available as separate downloadable files. Reports may be copied freely and cited with due acknowledgment. About IWMIIWMI's mission is to improve the management of land and water resources for food, livelihoods and the environment. In serving this mission, IWMI concentrates on the integration of policies, technologies and management systems to achieve workable solutions to real problems-practical, relevant results in the field of irrigation and water and land resources.

Water user associations: a review of approaches and alternative management options for Sub-Saharan Africa

“…An assessment of the contextual factors is used to identify specific challenges for WUAs in SSA, which will be referred to in the next section of this paper on alternative management options. This paper follows Namara et al (2010) to differentiate between 'conventional' and 'emerging' irrigation as two broad categories of irrigation systems in SSA. Conventional irrigation refers to those systems primarily developed by the state and often financed by public or donor institutions, such as development banks or bilateral development agencies.…”

Modernized Irrigation Technologies in West Africa

“…Ghana's irrigation systems may be classified into four major typologies based on such criteria as ownership/management, source of water, type of infrastructure or technology involved, and source of power for abstracting, conveying, and distributing water (Namara et al, 2010, Namara et al, 2011. These are:…”

Shallow groundwater in the Atankwidi Catchment of the White Volta Basin:current status and future sustainability

“…The farmers can irrigate about 0.69 ha of land with this technology. A detailed description of each type of these SGI systems can be found in Namara et al (2010). which a sample (GPS location) can be taken.…”

“…This could considerably reduce the time spent on digging and will also lower the risk of failure. The impact of SGI on livelihood security as well as its sustainability of the aquifer will be addressed in the modeling exercise and the socioeconomic survey recently conducted in the basin (Namara et al 2010).…”

“…A rope is tied to a bucket and the soil is collected and pulled out of the well until the water table is reached. A collaborative study between IWMI and the International Food Policy Research Institute (IFPRI) revealed that, wells for SGI have diameters ranging between 70 and 100 centimeters (cm) while they have a depth ranging between 1 and 9 m (Namara et al 2010).…”
