To examine the impact of small reservoir irrigation development in Africa, the performance and productivity of two small reservoirs and irrigation schemes in the Upper East Region of Ghana were investigated in this study. Hydrologic data measured included daily irrigation volumes and daily evaporation. Farmer cost inputs, excluding labor, and harvest data were also recorded. There was a strong contrast in water availability between the two systems, the Tanga system having a higher amount of available water than did the Weega system. The concept of relative water supply was used to confirm this disparity; Tanga was an inefficient system with a relative water supply of 5.7, compared to a value of 2.4 for the efficient Weega system. It was also concluded that the dissimilar water availabilities resulted in the evolution of very different irrigation methods and coincided with different management structures. Where there was more water available per unit land (Tanga), management was relaxed and the irrigation inefficient. Where there was less water available per unit land (Weega), management was well structured and irrigation efficient. The productivity of water (US$ m_3) of the Tanga system was half that of the Weega system, when analyzed at a high market price for crops grown. In terms of productivity of cultivated land (US$ ha_1), however, the Tanga system was 49% more productive than the Weega system. The difference in the productivity of land is primarily a result of increased farmer cash inputs in the Tanga system as compared to the Weega system. The difference in the productivity of water can be attributed to the varying irrigation methods and management structures, and ultimately to the contrasting water availability.

People living in arid areas often experience highly variable rainfall, droughts, floods and have insecure livelihoods. Small multi-purpose reservoirs are a widely used form of infrastructure for the provision of water. They supply water for domestic use, livestock watering, small scale irrigation, and other beneficial uses. Although clusters of reservoirs store significant quantities of water and effect on downstream flows, they have rarely been considered as systems, with synergies and tradeoffs resulting from their numbers and their density.
Often reservoirs were constructed in a series of projects funded by different agencies, at different times, with little or no coordination among the implementing partners. That a significant number are functioning sub-optimally and/or are falling into disrepair indicates that there is room for improvement in the planning, management, operation, and maintenance of small reservoirs. This first version of the Small Reservoirs Toolkit was produced by the Small Reservoirs Project. It is a project of the Challenge Program for Water and Food, sponsored by the German Technical Cooperation (Gesellschaft fuer Technische Zusammenarbeit, GTZ), led by the International Water Management Institute (IWMI) with six partners: Empresa Brasileira de Pesquisa Agropecuaria (Embrapa), L’Institute de recherché pour le development (IRD), Stockholm Environment Institution (SEI), Delft University of Technology (TUD), University of Zimbabwe (UZ), Ghana Water Research Institution (WRI). In 2005 the project began with two paired objectives. The basin/watershed level objective is to promote and support the planning, development, and management of small reservoir ensembles. The local/community level objective is to support use of small multi-purpose reservoirs that are properly located, well designed, well maintained and operated to improve the livelihoods of the local residents. A multi-disciplinary team was assembled to develop a set of tools based on socio-economic and biophysical research. The hydrologic, economic, ecological, health, and institutional dimensions of small reservoirs were considered. By harmonizing the interests of individuals served by small multi-purpose reservoirs and other people living in the basin we will come closer to our paired goals: 1) to maintain water related ecosystem services, the long-term sustainability of local water supplies, and adequate downstream flows as we make use of small reservoirs and 2) to improve food security and increase sustainable livelihoods through the use of those small multi-purpose reservoirs.
There are approximately 30 tools and techniques presented in four topic areas: i) Intervention Planning; ii) Storage and Hydrology; iii) Ecosystems and Health; iv) Institutions and Economics.
This tool kit is intended for the use of NGOs, research institutes, universities, donor agencies, multilateral organizations, and government agencies. These tools are not meant to replace other methods of collecting, storing, and presenting knowledge. Information in journal articles, dissertations, theses, and other literature is often difficult to find and is seldom written for use by practitioners. The purpose of the tools is to make information more accessible and more useful to practitioners. In the tools, references are made to the original documents. And it is expected that the reader will refer to and make use of the original documents where necessary.
Some of these tools are simple and applying them requires nothing more than the desire to try something new, and the drive to ‘get out and do it’. Undertaking them effectively requires, sometimes advanced, facilitation and communication skills. Here, we have aimed to provide comprehensive accounts of how to apply such techniques, with a focus on the requirements of potential facilitators. Some of the tools are more complex, and call for significant resources if they are to be used effectively. Here, we have attempted to provide an introduction and orientation to the topic at hand, as well as an introduction to resources that might prove useful to the reader The aim of this toolkit is to present entry points and references to the wide ranged topic of ‘Small Reservoirs’ and related research. This toolkit is a starting point. Other researchers will make additional contributions as part of the on-going process of expanding our knowledge of small reservoirs. References and contact persons are listed at the end of each tool.

Methods for estimating runoff that have been developed for temperate climates may not be suitable for use in the monsoonal climates of Africa, where there is a distinct dry season during which soils dry out to a considerable depth. This has a distinct effect on runoff generation that is not captured by “the temperate climate” models. The scope of this tool is to develop a simple water balance method for predicting river discharge. Water balance models have been shown to better predict river discharge in regions with monsoonal climates than alternative methods based on the United States Department of Agriculture-Soil Conservation Service (USDA-SCS) curve number. The latter is an empirical-based model developed in the USA that does not apply to monsoonal climates with distinct dry and wet periods.

Agricultural (water) development is once again at the fore of the development agenda of sub-Saharan Africa. Yet, corruption is seen as a major obstacle to the sustainability of future investments in the sector but there is still little empirical evidence on the ways corruption pervades development projects. This paper documents the planning and implementation processes of two specific small reservoir programmes in the north of Ghana. We specifically delve into the dynamics of corruption and interrogate the ways they add to the inherent unpredictability of development planning. We argue that operational limitations of small reservoirs such as poor infrastructure, lack of managerial and organisational capacity at the community level and weak market integration and public support are the symptoms – rather than inherent problems – of wider lapses in the planning processes that govern the development of small reservoirs in Ghana and plausibly worldwide. A suite of petty misconduct and corrupt practices during the planning, tendering, supervision, and administration of contracts for the rehabilitation and construction of small reservoirs results in delays in implementation, poor construction, escalating costs, and ultimately failures of small reservoirs vis-à-vis their intended goals and a widely shared frustration among donor agencies, civil servants, contractors, and communities. Such practices hang on and can only be addressed through a better understanding of the complex web of formal decisions and informal rules that shape the understanding and actions of the state.
