Value chain development is an important strategy to achieve sustainable development for smallholder farmers. It focuses not only on farmers and their direct livelihood but recognizes that sustainable agricultural projects ought to consider the entire production process by not only improving the factors of production for smallholder farmers but also allowing for greater integration into local markets, and the strengthening of key stakeholders along the value chain. The Agricultural Value Chains Support Project (in French Projet d'Appui aux Filières Agricoles (PAFA)) capitalizes on the value chain approach to improve the livelihoods of smallholder farmers in Senegal's Groundnut Basin. Approved in 2008 and put into effect on February 5th 2010, the Agricultural Value Chains Support Project has, as of today, reached 37,734 households. The project is articulated around five components: (1) agricultural diversification and access to local market (2) development and structuring of regional value chains, (3) national coordination, knowledge management and project management, (4) climate change adaptation, and (5) support services for rural finance. The project was innovative in that, in addition to providing support to farmers through producer organisations (POs), there was an emphasis on improving concertation and collaboration around key value chains.

"This paper examines the impact of IFAD-supported projects so as to learn lessons for future projects. It analyses the different methods used by IFAD to measure a project's impact, finds that IFAD is improving the well-being of rural people, and recommends that impact assessments be built into future projects from their inception."--

In recent years, the International Fund for Agricultural Development (IFAD) has increasingly strengthened its focus on achieving and measuring results. In 2011-2012, resources were invested in the IFAD9 Impact Assessment Initiative (IFAD9 IAI) in order to: (i) explore methodologies to assess impact; (ii) measure - to the degree possible - the results and impacts of IFAD-financed activities; and (iii) summarize lessons learned and advise on rigorous and cost-effective approaches to attributing impact to IFAD interventions. The initiative reflects a recognition of IFAD's responsibility to generate evidence of the success of IFAD-supported projects so as to learn lessons for the benefit of future projects. This paper describes the IFAD9 IAI and the range of methods that have been identified to broaden the evidence base for the estimation of IFAD impacts, and presents the results from the aggregation and projection methodology used to compute the Fund's aggregate impact on key outcomes, while also highlighting what has been learned. The results show that there are many areas in which IFAD-supported project beneficiaries have had, on average, better outcomes in percentage terms as compared to comparison farmers who were not project beneficiaries. Specifically, IFAD-supported projects are effectively poverty-reducing: when choosing durable asset indexes as the preferred poverty proxies on the grounds that they better approximate long-run wealth, findings point to statistically significant gains. Overall, the analyses strongly imply that IFAD is effectively improving the well-being of rural people in terms of asset accumulation, and higher revenue and income. The IFAD9 IAI represents a pioneering research effort, which has tried to overcome the clear challenges of designing data collection and conducting ex post impact assessments in a context where data were scarce, with a view to measuring progress towards a global accountability goal over a very short period of time. Therefore, an important recommendation is that future impact assessments should be selected and designed ex ante, and structured to facilitate and maximize learning, rather than used solely as an instrument to prove accountability.

Smallholder farmers in developing countries often lack appropriate cereal storage facilities which can contribute to food insecurity and low cereal commercialization, particularly when they can only rely on one cropping season with no irrigation. Lack of quality storage can lead to post-harvest losses (Abass et al, 2014; Sheahan and Barrett, 2017) and often compels smallholder farmers to sell their crops soon after harvest, when crop prices are at their seasonal lowest, only for them to buy grain for consumption during the lean season, when prices are high (Kadjo et al, 2018; Aggarwal et al, 2018; Stephens and Barrett, 2011). In many instances, such farmers need food assistance to survive the lean season and in other cases, they may have to borrow money at usurious rates in order to purchase food. This was the case in Guéra Region of Chad, a semi-arid area that frequently experiences droughts and dry spells in ways that severely reduce crop production and rural households' food security. To address these issues, the IFAD-funded Programme d'Appui au Développement Rural dans le Guéra (PADER-G) project was implemented with the main objective of supporting poor rural households and smallholder farmers in Guéra, Chad to improve their food security and livelihoods. One specific aim of PADER-G, designed to manage risks of food shortage, was to improve cereal storage among smallholder farmers through the construction of community cereal banks (banque de céréales). This main element of the project was complemented with the establishment of community committees (Comité de gestion des banques de soudure - COGES) which were trained on effective management of the cereal banks.
