“…But we cannot merely replicate agricultural R&D patterns of the past. First, agricultural R&D increasingly needs to aim to mitigate the adverse effects of climate change on productivity growth (Hertel and de Lima 2020). Anthropogenic climate change has been a strong headwind in the face of technological change, reducing global agricultural TFP growth by an estimated 21% since 1961, equivalent to losing roughly a decade's productivity growth (Ortiz‐Bobea et al 2020).…”

The world faces formidable, but manageable, challenges in achieving food security in a world growing beyond 9 billion people in the coming decades. Five big challenges will necessitate shifting innovation strategy to place greater emphasis on sustainable increases in diet quality, on total factor productivity ‐ not just crop yield ‐ growth, on social protection programs, on Africa, on post‐farmgate agri‐food value chains, on risk management, and on reducing the land and water footprint of food production. We must be progressive in both senses of the term, having faith in science as an engine of societal advance, and standing with marginalized populations.

“…As is well known, C3 plants are more vulnerable to elevated temperature and CO 2 levels than C4 plants (Lamboll, Stathers, & Morton, 2017). Damage due to crop diseases, pests and weeds extending their range under climate change is already vast, although to some extent predictable based on their presently known environmental adaptation (Hertel & de Lima, 2020). Other impacts on crop physiology, such as pollen maturation and survival, are complex.…”

“…Draft animals are likely to have similar declines in productivity as temperatures rise. And yet, these effects of climate change on agricultural labor productivity in many lowincome countries are rarely taken into consideration, while already part of legislature in industrialized countries (Hertel & de Lima, 2020).…”

“…The UN and the African Union Commission recommend that developing countries invest 1% of GDP in agricultural research, but in 2016 the vast majority of these countries reached at most only 0.3% of GDP (Beintema, Pratt, & Stads, 2020). R&D should not just aim to increase calories from a few staple crops, but also nutrients from other food groups, including fruits, vegetables, meat, eggs, and milk (Pingali & Aiyar, 2018;Hertel & de Lima, 2020).…”

Prioritizing Achievable Goals for Food Security in the Developing World

Many solutions have been proposed to address food security. We present here a prioritized set of actions achievable within the next 2–10 years. By taking a systems approach we follow the impact pathway backwards starting from the needs and desires of the end-users to eventually define the research agenda that will exactly address those targeted solutions with positive impacts. The following actions emerge as high-priority and achievable in the near future: new research tools to study food systems; dis-aggregated intra-household surveys to reveal within-family inequalities in food access; increased scientific consensus on climate change impacts in sub-Saharan Africa; rapid response measures to address sudden emergencies, such as capturing excess rainfall water; financial tools to enable rapid responses with recovery measures afterwards; consideration of restrictions that excess heat and humidity impose on human productivity; secure land ownership and tenure rights to encourage long-term agricultural investment; mechanization at all stages along the food system.

“…Despite the fact that the share of agriculture in the region's GDP has almost halved since 2000 [1], it represents an average of 5% of the region's GDP [1]. However, it should be noted that agriculture is the most susceptible branch of the economy as far as climate is concerned [2]; global warming and climate change, which according to experts will keep getting worse, pose serious threats to crop and livestock farming in the region [3]. As recent studies show, Europe is warming faster than the rest of the world: by 1.7-1.9 °C compared to 0.94-1.03 °C for 2010-2019, [4] and Eastern Europe is especially dry [5].…”

The aim of the study is to elaborate an econometric model to determine the conditions for ensuring the balanced development of environmental, economic, and social components of the Russian agricultural sector within the Eastern European region. The method of fuzzy sets was used to build an integral model for assessing the level of sustainable development of the agricultural sector in Eastern Europe on the basis of economic, environmental, and social sustainability indicators. The control indicators (independent variables) and integral economic, environmental, social sustainability (dependent variables) helped build multifactor linear regression models and calculate the indicators of elasticity of dependent variables from independent variables, which characterize the change in sustainable development indicators with the growth of controlling factors by 1%. This model allows us to define and analyze the levels of sustainable development of the industry, both in a specific country and within the region in general. The study shows that, for Russia and Eastern European countries, innovation is one of the crucial factors in ensuring sustainable development of agriculture in the region, taking into account the current state and level of economic development.
