Abstract

We look at the prioritisation of agricultural value chains (VCs) for the allocation of R&D resources that maximise development outcomes (poverty, growth, jobs and diets) in Senegal. This study used (a) the rural investment and policy analysis (RIAPA) computable general equilibrium (CGE) model; (b) the perpetual inventory model (PIM), and (c) information on the elasticities of VC total factor productivity (TFP) with respect to R&D knowledge stocks (KS) to discuss the value chain priority allocations of R&D resources. The results indicate that no value chain is the most effective at improving all outcomes. The most effective value chains to be efficiently supported through R&D investments are traditional export crops, groundnuts, rice, poultry, sorghum/millet and cattle. Other promising value chains with potential effects at scale include vegetables, oilseeds and fruits. Future modelling needs to focus on deepening the standardisation and integration of R&D investments in this framework and bring together other factors and complementary agri-food system (AFS) investment dimensions that are relevant to sustainable and inclusive agricultural growth.

撒哈拉以南非洲的农业研发投资和发展目标:评估塞内加尔价值链的优先次序

我们关注农业价值链（VC）的优先顺序，以分配研发资源，最大限度地提高塞内加尔的发展成果（贫困、增长、就业和饮食）。本研究使用了（a）农村投资和政策分析（RIAPA）可计算一般均衡（CGE）模型；（b）（c）VC全要素生产率（TFP）相对于研发知识存量（KS）的弹性信息，以讨论研发资源的价值链优先级分配。结果表明，在改善所有结果方面，没有价值链是最有效的。通过研发投资得到有效支持的最有效的价值链是传统出口作物、花生、大米、家禽、高粱/小米和牛。其他具有潜在规模效应的有前景的价值链包括蔬菜、油籽和水果。未来的建模需要侧重于深化该框架中研发投资的标准化和整合，并将与可持续和包容性农业增长相关的其他因素和补充农业食品系统（AFS）投资维度结合起来。

期刊介绍： The African Journal of Agricultural and Resource Economics (AfJARE)/Journal Africain d’Economie Agricole et des Ressources (JAEAR) is a publication of the African Association of Agricultural Economists (AAAE). The journal publishes original research about how African agriculture interacts with local and global economic systems and policy regimes in its impacts upon people. The scope of the journal covers the roles of markets, technology, policy, institutions and the natural environment in shaping the lives of well being of Africans engaged in agricultural activities. The journal strives to nurture and enhance the capacity of African professionals to conduct and publish scientific research and provides a venue for communicating and disseminating their findings. Multi-disciplinary, problem-oriented articles are encouraged. Submissions may deal with teaching, research extension, consulting, advising, entrepreneurship and administration. The Chief Editors and Editorial Board, under the general direction of the AAAE President, Executive Committee and Council are charged with implementing Journal policy to serve members of AAAE. The main section of the journal publishes technical research articles while a small section is devoted to publishing brief notes with important policy content and book reviews. The journal is a quarterly publication.
