Analysis of the productive systems in the Anambé irrigation scheme (Niandouba and Confluent dams, Senegal)

English

The development of irrigation is one of the priority strategies in the Sahel countries to tackle poverty and food insecurity. At a time when governments are once again committing to increase irrigable areas, it seemed relevant to analyze, in line with the ECOWAS guidelines, the results achieved in large irrigated schemes developed in the 1980s and 1990s to draw lessons for future developments.

Irrigation, food security and poverty – Lessons from three large dams in West Africa

English

In recent years, the governments of the Sahel have committed to combat poverty and food insecurity through a significant increase in the development of irrigable areas. For GWI West Africa, this has presented a timely opportunity to analyse, alongside the relevant ECOWAS guidelines, the socio-economic results achieved on irrigated schemes associated with large dams in the West Africa region.

Towards a shared vision: action plans for adapted advisory services in West Africa’s rice irrigation schemes

English

Farmer organisations and government agencies managing large scale irrigation systems in West Africa need to collaborate to agree on a vision for agricultural services that increases scheme viability while meeting the needs of different types of farmers. However, there is no institutional mechanism in place that enables different groups of actors – with different levels of power – to engage at a strategic level or to negotiate and take forward such a common position.

Towards a shared vision: Advisory services that work for smallholders and government in West Africa’s large irrigation schemes

English

Large government-managed irrigation schemes in West Africa are expected to meet the ambitious rice production targets of governments and ensure the livelihoods of small scale rice producers. Functioning institutions are a prerequisite for achieving these sometimes conflicting objectives.

Workshop on irrigated land tenure in the Sahel (Task Force for implementing the 'Dakar Declaration')

English

This is the report of a workshop held on 8 and 9 June 2015 in Bamako, Mali, to present and discuss the results of a study on securing irrigated land tenure in the six countries within the Permanent Inter-State Committee for the Fight against Drought in the Sahel (CILSS) in the context of the "Dakar Declaration".

Background

Financing family rice farming to improve performance of large dams

English

Governments need to improve access to seasonal credit if they want a return on investment in large-scale irrigation for rice farming. Large dam-irrigated rice cultivation projects are only justifiable if producers can obtain high yields, but to do this they need to adopt rice varieties with high genetic potential and make intensive use of fertilisers and pesticides. The majority of small producers do not have access to credit to purchase all the inputs required.

Ex-post economic evaluation of the Niandouba et Confluent dams in Senegal

English

This report conducts an ex-post evaluation of the wealth produced by the Niandouba and Confluent dams in Senegal. It provides a financial assessment of the dams for the state and draws lessons for future intervention anbd planning. The report seeks to nurture the wider debate and reflexion on the costs and benefits of large dams in West Africa. 

The Global Water Initiative (GWI) in West Africa, is an initiative funded by the Howard G. Buffett Foundation and implemented by IIED with IUCN.

Action plan to improve agricultural advice services in the Anambé valley in Senegal

English

This document, based on a consensus between stakeholders, sets out a roadmap for the development of effective agricultural advice services and the improvement of agricultural productivity in the Anambé basin. 

The Global Water Initiative (GWI)'s action-reserarch work in Senegal has shown that agricultural advisory systems are inefficient and ill-adapted to the needs of smallholders. With support from GWI, stakeholders from the basin therefore met at various workshops to discuss how to address this issue and establish an action plan. 

Pages

Our work in Senegal focuses on supporting smallholders who are farming, transforming and trading rice in the irrigated area around the Niandouba and Confluent dams in the Anambé river basin. We are also looking at the overall economic impact of the dams, both in terms of their overall return on investment, and in terms of how they improve the livelihoods of the affected communities.

Irrigated agriculture, and rice in particular, play a key role in national food security policies, namely through the National Social and Economic Development Strategy (SNDES) and the National Rice Self-Sufficiency Plan (PNAR).

Niandouba and Confluent dams

In order to reduce Senegal’s cereal production deficit and to bolster the livelihoods of local producers through irrigated agriculture, the national authorities decided in the 1970s to develop the Anambé river basin. The basin (which covers an area of 1,100km²) is in the Haute-Casamance area in the Kolda region in southern Senegal and is drained by the Kayanga river and its tributary, the Anambé river. In 1984, a dam was built at the confluence between the two rivers, followed in 1997 by the construction of a second dam on the Kayanga river at Niandouba. The dams, known as the Niandouba and Confluent dams, are interlinked and work together to provide water for the irrigation schemes, which cover 5,000 hectares.

There are seven local districts (known as ‘communes rurales’) in the area covered by the Anambé river basin. The development of the area reshaped local livelihood systems and gave irrigated agriculture a central role, although there remains a strong pastoralist tradition amongst the people living in the Anambé basin.

The Society for Agricultural and Industrial Development in Senegal (SODAGRI) was created in 1974 as a public limited company with technical oversight from the Ministry of Agriculture and is responsible for the management of Niandouba and Confluent dams and the associated irrigation schemes.

Reducing conflict over land through community participation

Access to water and the use of land in the irrigation schemes can often be a source of conflict between farmers and pastoralists. During 2012-2013, GWI West Africa worked with four communities in the Anambé river basin to promote understanding and implementation of local resource use agreements known as ‘Land use and allocation plans’ (Plans d’occupation et affectation des sols – POAS). The proposed structure of these agreements were set out as far back as 2008, but there had not been any information dissemination or capacity building to implement them. Following our work with local communities and the SODAGRI on the POAS, the number of conflicts over land use dropped dramatically in the communities involved.

Assessment of rice-producing smallholders

We have looked at the different types of rice producers in the irrigated perimeters of the Niandouba and Confluent dams and in particular at how their methods of farming differ and consequently how their needs differ. We carried out similar research in Mali and Burkina Faso and in 2014 published a synthesis of the findings which provides a comparative analysis across all three countries.

Agricultural advisory services

Our research on the issues faced by rice-producing smallholders has indicated two important areas that need to be addressed to support productivity and livelihoods of smallholders in Senegal:

  • Improved agricultural advisory services
  • Strong farmer organisations

We are working with all the stakeholders concerned in the irrigated perimeter of the Niandouba and confluent dams – including both SODAGRI and local farmer organisations – to identify the key challenges to establishing improved and appropriate agricultural services.

An economic assessment of Niandouba and Confluent dams

In parallel to our work with smallholder rice producers, we are also carrying out an economic analysis of the Niandouba and Confluent dams to evaluate the impact that they have had both as a national investment, and in terms of local livelihoods.

We are undertaking similar analyses in Burkina Faso and Mali, which will help us to draw out some comparisons and conclusions at a regional level. This forms part of our wider work on developing awareness and debate about the livelihood impacts and economic viability of intensive, large scale irrigation schemes.
