Historical background of irrigation in Africa
While historically irrigation was not common among individual African farmers, large scale irrigation schemes were introduced during colonial times. Initially slaves, and later on unpaid laborers, worked on the fields of these schemes without having any say in management or marketing. This total lack of participation was extended until the 1970s, becoming less pronounced in the 80s and 90s, when farmers eventually got a little payment for their work but still had almost no power or decision-making competences concerning what and how they produced. In addition to this problematic background of irrigation in Africa, most of the large governmental schemes couldn’t meet the aligned economic expectations, i.e. they were neither productive, nor financially or environmentally sustainable. As a consequence of these failures, most of these large scale irrigation schemes were closed down during the 90s, or in some cases taken over by farmers. Several of the schemes were then mismanaged and then destroyed by the untrained farmers. Others, however, were re-organized, with farmers enabled to participate in decision making over crop production and marketing of the crops, as demonstrated in some schemes in Kenya (see Neubert et al. 2007).
Most donors, including the World Bank and the German Development Cooperation, had withdrawn from large irrigation projects by the 90s, engaging only occasionally in the rehabilitation of schemes (if profitable management seemed possible) or in some scattered smallholder irrigation projects. But in the last decade, irrigation as a whole has undergone a significant change, and is aligned with national sector reforms in most of the African countries. Policies are oriented more and more towards the support and the facilitation of smallholder irrigation schemes, and public authorities created, sometimes with the support of international development cooperation, new legal frameworks, in which farmers’ participation, financial, environmental and social issues are framed or regulated. These reforms sometimes include basic approaches, i.e. first steps for measuring water withdrawals which eventually will enable for charging water withdrawals, as one of the most important steps towards achieving efficient water uses.
Small-scale irrigation policies in practice
The emerging water policy initiatives must take note that an integrated view according to the concept of IWRM/ Integrated Water Resource Management needs to be taken into account for planning irrigation systems, as well as managing them. While the benefits of small-scale irrigation may have accrued largely to the land owning class, irrigation provision also increases labor requirements and wage rates, thereby also providing benefits for the landless and land-poor.
In order to reach the poor, it is necessary to target both specific regions where poor population groups can benefit, and sites which are economically and environmentally suitable for irrigation. This might be a difficult task, because very often high potential areas with access to surface water are already populated by better-off farmers who may already be engaged in irrigation. In such cases, it might be more reasonable to shape the systems already in place and advise these farmers how to improve their systems, including the value chain, rather than focusing on very poor farmers in marginalized areas, where irrigation is less promising (see Neubert et al. 2007).
But in other cases, it also make senses to support the establishment of new irrigation systems for disadvantaged populations, e.g. for nomads or other underprivileged groups. This may especially timely as increasing climate variability can make the survival of transhumance cultures extremely difficult. In such cases, supported engagement in irrigation can relieve people from hunger and, in particular empower women to make their own living by engaging in irrigation and business during the times when their husbands are absent with their cattle in search for water. The World Bank has undertaken such an approach with regard to the Massai population (see Neubert, et al. 2007).
Since many poor farmers cannot afford motorized pumps (such pumps may also deplete water resources quickly), treadle pumps (TP) can be promoted, as is done by Enterprise Works Worldwide (EWW). Adeoti et al (2007: 1) state that in Ghana almost 30 per cent of the farmers could increase their incomes significantly by using treadle pumps. However, other farmers have stopped using the treadle pumps, either because the pumps broke down or they were only useful over small pieces of land. The authors recommend that a variety of improvements in design, dissemination and capacity may still be necessary to improve the impact of TP technology. Increased collaboration with local institutions, such as extension services, could make the TP more appealing to farmers. Design improvements should be undertaken to ease pedaling, which would encourage the uptake of the TP by women and enhance their chance of benefiting directly. The introduction of after-sales service and training of farmers on minor repairs would also improve the continuous use and sustainability of the TP (ditto).
As can be seen from these examples, agricultural water and poverty are intricately linked, but the nature of that linkage is not straightforward. In general, the experience suggests that agricultural water is, on the whole, associated with poverty alleviation. However, it is also very often found that the provision of agricultural water has also some negative poverty-increasing aspects. Furthermore, the distribution of costs and benefits from irrigation services are often not uniform. Often the most disadvantaged members of society benefit the least, or are even hurt the most, by agricultural water’s negative side-effects. Hence, Hussain/ Giordano (2004) suggest that researchers, policy makers and project implementers, public and private, must have a deep understanding of the many, often hidden, linkages between water and poverty if potential poverty reducing impacts of agricultural water are to be realized, and the benefits of agricultural water equitably shared.
Approaches of the German Development Cooperation
Approaches of German Development Cooperation mainly have a more general focus on the national and sub-national level, aimed at improving the institutional frameworks and the governance of water in order to increase social and environmental sustainability and the profitability of irrigation.
- Sector reforms
German Development Cooperation advises national authorities on the introduction of sustainable forms of land and water resources management. It provides this advice as part of larger strategies for the management of water catchment areas. GIZ, as executing agency of the German Development Cooperation adapts existing concepts that have already been tested in practice, to bring them in line with regional and local conditions, and train executives and employees of the relevant organizations. German Development Cooperation is also advising state bodies on land and water law reforms.
- Governance
GIZ helps to build institutions and also advises organisations involved in water use in agriculture, including water user and marketing associations. By doing so, they promote women in particular, who are still minor stakeholders in irrigated agriculture. GIZ also takes into account existing access and utilisation rights, and aims for an equitable distribution of water resources.
- Adapting to climate change
German Development Cooperation raises awareness among relevant partner organisations of the expected impacts of climate change on water use in agriculture, and advises them on appropriate adaptation measures. They work to ensure that these measures are identified at an early stage and that they become an integral part of water and land management.
- Water management in agriculture
GIZ passes on tried and tested cropping and irrigation techniques that are adapted to specific local knowledge and regulations. At the same time they provide expert advice on the use of agricultural inputs and marketing. GIZ fosters contacts with the private sector, so as to harness its contribution to making water management more effective and user oriented. Finally, GIZ also supports the ecologically sound and healthy use of water of marginal quality (brackish water and treated wastewater).
Project example: Mali
Programme Nationale d’Irrigation de Proximité (PNIP), Mali
National Programme of irrigation in proximity, Mali
Apart from decentralization, rural development was in the focus of the German Development Cooperation for several decades in Mali. High poverty levels, low and uncertain precipitation patterns and - as a result - a very low food security are the major problems.
Because there is a high potential of irrigated agriculture along the river Niger the National Program of irrigation has been created, aligned with the national framework. The overall objective of the program was a reduction of poverty and job creation. The cooperating partners were the Ministry of Agriculture, its regional agencies and the GIZ. The participation and engagement of farmers, communities, service providers and public authorities was regarded as a crucial component. The direct support consisted in financial means and credit provision, capacity development of government officers and farmers, and the strengthening of coordination capacity as well as support in the elaboration of management plans. However, during the ten years of its existence the PNIP helped to improve the management of about 120.000 ha agricultural lands from about 3 million people.
