Well-funded agricultural research and development (R&D) systems play an important role in transforming agrifood systems and helping countries to achieve the Sustainable Development Goals. The advantages of investing in agricultural R&D are also clear from looking at the past, where a wide range of studies have clearly demonstrated the substantial benefits that resulted from investments in agricultural R&D. The importance of investing in R&D has also been highlighted by governments on numerous occasions in intergovernmental settings. Gathering, compiling and analysing multi-year, multi-country datasets on investments in agricultural R&D are complicated tasks that require a lot of meticulous work and dedication. Only a small number of groups have worked actively in this specialized area. In some cases, they have used different procedures for gathering data on public and private sector investments in agricultural research. This report reviews the current situation and trends regarding investments in agricultural R&D in the world and presents some clear results that emerge from recent studies.

Since CGIAR centers have been in existence for a number of years, this paper addresses the impact of these centers on national research and extension programs and crop productivity. The study estimates that the CGIAR Centers have had a positive impact on investment in national research programs in each of the crops for which CGIAR crop programs exist except cassava. Estimates for livestock and horticultural crop research programs show a significant positive CGIAR impact as well. National extension spending is also stimulated by CGIAR programs. These estimates are based on an econometric specification that takes into account the impact of several economic development aid initiatives in addition to the activities of the CGIAR impacts. The study estimates that CGIAR Center programs have had significant impacts on crop productivity for maize, millets, sorghum, rice, wheat, beans, cassava and potatoes in all the regions studied. National research programs have had a positive impact on crop productivity in most of these crops as well. In addition, national extension programs have been productive in some crops. These estimates are based on crop production data in 25 countries.

The primary role of international public agricultural research is undoubtedly to address key social, environmental, and economic goals at the global level. Further, there is consensus that investment must be accelerated in research-based innovations focusing on sustainable food systems. And given the relatively weak situation of many national agricultural research systems in the global South, it is imperative to reach economies of scale in investments in international initiatives. It is not yet clear, however, how much additional investment is needed or how scarce resources should be allocated across priority research-for-development challenges. At the international level, growing consensus indicates that—in addition to increasing funding—far greater harmonization is needed in funding and executing research in order to more effectively tackle global agricultural research challenges. Growing opportunities for technology spillovers and research alliances to occur across national, regional, and international boundaries necessitates the ability to access new technological knowledge from a variety of sources. And since access to new technologies is closely related to the capacity to generate new technologies, the need to strengthen and harmonize national, regional, and global research systems becomes even more of a priority. Although the role, contributions, and impacts of the CGIAR have been analyzed by many authors, only a few have summarized the recent evolution of its financing. This note is intended to contribute to reflections on the CGIAR’s first 50 years, which it will celebrate in 2021, while also providing a useful reference for the current “One CGIAR” governance and management transformation.

This report assesses trends in investments, human resource capacity, and outputs in agricultural research in SSA, excluding the private (for-profit) sector. The analysis uses information collected by Agricultural Science and Technology Indicators (ASTI)—led by the International Food Policy Research Institute (IFPRI) within the portfolio of the CGIAR Research Program on Policies, Institutions, and Markets (PIM). The comprehensive datasets were derived from primary surveys, collected through a series of consecutive data collection rounds; a small number of secondary sources, where survey data were missing or of poor quality; and ASTI’s older investment and human resource datasets. This report highlights the cross-cutting trends and challenges that emerged from the country-level data, structuring it within four broad areas: funding capacity, human resource capacity, research outputs, and institutional conditions—all in terms of whether they support or impede the effective and efficient conduct of agricultural research. This report concludes with a set of policy recommendations for regional and national-level decision makers, and other stakeholders.

Impact of agricultural research with particular emphasis on the contribution of the international agricultural research centers; A preliminary model of optimal investment in agricultural research.

The 2019 report of the Global Commission on Adaptation for accelerated action to adapt to climate change included a call for increased allocation of resources to international agricultural research. The production and adaptation challenges faced by agriculture will be most acutely felt in Africa and South Asia, focus regions of the CGIAR, the world’s largest public food systems research network. These challenges come at a time when the CGIAR is undergoing a transformation of its partnerships, knowledge, assets and global presence, emerging as One CGIAR, aimed at sharpening its mission and impact focus to 2030 and beyond, in line with the Sustainable Development Goals. Evidence on the impacts of CGIAR research since the 1980s have consistently found high rates of return to investment. How could this evidence on the performance of the CGIAR and its partnership with NARS in developing regions be used to inform investment priority setting and to achieve the One CGIAR goals in the coming years? We used detailed R&D investment data from the CGIAR, NARS (ASTI) and evidence from the literature on returns to CGIAR investment by crop and region to develop and calibrate a model of R&D investment that allows us to conduct priority-setting analysis of alternative CGIAR investment across research activities and regions. The model developed can be linked to global partial equilibrium and economy-wide forward-looking models to analyze the effect of different CGIAR investment options under alternative future scenarios. We checked the plausibility of the results obtained by the model calculating the Benefit-Cost ratio of historical CGIAR investments and found that each dollar invested by the CGIAR between 1971 and 2018 returned almost 10 dollars in output as the result of increased productivity, which is within the range of returns found by most recent meta-analyses impact of CGIAR investment. An application of the model to SSA shows that the best results for the CGIAR are obtained from investments in cassava and potato in Southern Africa; yams, sorghum, cassava and groundnuts in West Africa; cassava in East Africa and groundnuts and shoats in the Sahel.
