This new paper from IFDC outlines the role of soil in mitigating and adapting to the effects of climate change while also being influenced by these changes – a complex two-way relationship.

The authors first provide an understanding of this relationship before discussing the direct and indirect pathways through which soil health impacts carbon sequestration. Next, they highlight global evidence on soil health’s role in ecosystem services, including its ability to promote resilient, climate-adaptable systems.

Then, they discuss how these beneficial effects are under threat, as the increase in climate change-induced events limits the ability of soil to mitigate and manage climate change. Finally, they conclude by identifying areas where further action and research are needed. 

A new paper from IFDC seeks to elaborate on this theory of change and build the case for improving soil health as a pathway to food security.

The paper begins with an overview of how soil health is critical to multiple SDGs, including SDG 2: Zero Hunger. It then discusses the challenge of global hunger; including its persistence and rising trend in recent years.

Next, the authors delve into approaches that are critical to improving soil health so that crop systems can thrive. Next, is a look at not just overall food availability but the challenge of hidden hunger which is closely linked to levels of plant nutrition and healthy soils, before concluding with the caveats of the assessment.

In his Nobel Prize acceptance lecture, economist Theodore Schultz (1979) remarked, “Most of the world’s poor people earn their living from agriculture, so if we knew the economics of agriculture, we would know much of the economics of being poor”. If agriculture, then, largely determines the fate of the world’s poor, soil health has a fundamental role to play, given its impact on agriculture. In this paper, we lay out the deep relationships between soil health, agriculture, and poverty, and their implications for policy making. We focus on the United Nations Sustainable Development Goal 1 (SDG 1): No Poverty (United Nations, n.d.- a), which seeks to end poverty in all its forms everywhere. Extreme poverty is defined as surviving on less than $2.15 per person per day, at 2017 prices. We use the Intergovernmental Technical Panel’s definition of soil health: “. . . the ability of the soil to sustain the productivity, diversity, and environmental services of terrestrial ecosystem” (FAO, 2020).

Abstract

Being critical to achieving Sustainable Development Goals (SDGs) of the United Nations, strengthening understanding of the properties and processes of soil at national and regional scales is imperative. The necessity to realize SDGs by 2030 also inspires a greater sense of responsibility and care for soils…
