Mapping and linking supply- and demand-side measures in climate-smart agriculture. A review

Climate change and food security are two of humanity’s greatest challenges and are highly interlinked. On the one hand, climate change puts pressure on food security. On the other hand, farming significantly contributes to anthropogenic greenhouse gas emissions. This calls for climate-smart agriculture—agriculture that helps to mitigate and adapt to climate change. Climate-smart agriculture measures are diverse and include emission reductions, sink enhancements, and fossil fuel offsets for mitigation. Adaptation measures include technological advancements, adaptive farming practices, and financial management. Here, we review the potentials and trade-offs of climate-smart agricultural measures by producers and consumers. Our two main findings are as follows: (1) The benefits of measures are often site-dependent and differ according to agricultural practices (e.g., fertilizer use), environmental conditions (e.g., carbon sequestration potential), or the production and consumption of specific products (e.g., rice and meat). (2) Climate-smart agricultural measures on the supply side are likely to be insufficient or ineffective if not accompanied by changes in consumer behavior, as climate-smart agriculture will affect the supply of agricultural commodities and require changes on the demand side in response. Such linkages between demand and supply require simultaneous policy and market incentives. It, therefore, requires interdisciplinary cooperation to meet the twin challenge of climate change and food security. The link to consumer behavior is often neglected in research but regarded as an essential component of climate-smart agriculture. We argue for not solely focusing research and implementation on one-sided measures but designing good, site-specific combinations of both demand- and supply-side measures to use the potential of agriculture more effectively to mitigate and adapt to climate change

Environmental sustainability and the food system

The food system and the natural environment are closely linked. Indeed, food production strongly relies on environmental resources and services, and releases outputs into the environment. This implies that food-related activities can create negative externalities for the environment, for example related to overexploitation and pollution, given that the market fails to deliver the socially optimum level of resource use and/or pollution. Given this market failure, public intervention is required to regulate such activities. Public intervention can take different forms, from no intervention to simple guidelines up to strict regulation. Indeed, regulation can follow either an approach that outlines general principles or that fixes specific standards, or that promotes information and education. The aim of this chapter is to highlight the issues of environmental sustainability in the context of the agri-food system and to discuss current public and private initiatives that regulate the market from an environmental perspective. Thus, in this chapter we firstly introduce the concept of sustainability, including all the three pillars (profit, people and planet) and then discuss the issues of environmental sustainability related to food. Moreover, we discuss the different forms of public intervention and then we present European regulation that relates to environmental sustainability within the food system, including public and private voluntary initiatives. Furthermore, we discuss the interest of consumers for environmental sustainability and their perception of the impact of food production on the environment. Moreover, we analyse synergies between environmental sustainability and health issues. Concluding remarks follo
