Between 21–37% of all greenhouse gas (GHG) emissions are attributable to our global food system, from agriculture and land use, storage, transport, packaging, processing, retail, and consumption. As increased GHG levels further accelerate climate change, warming over land is occurring at a rate faster than the global average, with observable impacts on the land system. Traditional agricultural practices and arable land misuse have contributed to the degradation of roughly 75% of the Earth’s land area.
In addition to land degradation, the European Commission Joint Research Centre estimates 36 billion tons of soil is lost every year (Moyer, 2020). Depletion of soil nutrients, due to various natural and anthropogenic activities, affects people and ecosystems throughout the planet, and is both influenced by climate change and contributes to it. Warmer temperatures and changing precipitation patterns alter the beginning and end of growing seasons, contribute to regional crop yield reductions, reduce freshwater availability, and push biodiversity toward an unforgiving cliff (IPCC, 2019).
Recent studies indicate we are facing a biodiversity catastrophe, with 1,000,000 species at significant risk of extinction due to the climate crisis and habitat loss (Moyer, 2020). The frequency and intensity of extreme weather and climate events have also increased due to global warming and will continue to increase under medium and high emission scenarios (IPCC, 2019).
That is not to say that all hope is lost. Amid an abundance of dismal facts and figures, our species maintains both the responsibility and the capacity to discontinue extractive and degrading land use practices and implement large scale restorative and sustainable processes. Regenerative agriculture is a systems approach to farming that builds soil health by supporting biodiversity to return carbon and nutrients back to the soil. It is a holistic land use practice that can involve diversifying crop rotations, planting cover crops, green manures and perennials, retaining crop residues, using natural sources of fertilizer such as compost, employing highly managed grazing and/or integrating crops and livestock, reducing tillage frequency and depth, and eliminating synthetic chemicals (Moyer, 2020). Agro-ecology systems (systems that incorporate natural ecological processes with agricultural production) have many rewards to society, including increases in local income and nutrition, as well as a drawdown of CO₂ back into the soil (Chainlink, 2021). Regenerative agriculture focuses not only on reducing the carbon footprint and ensuring sustainability, but also on going beyond conventional practices to reverse the effects and progression of climate change. Indigenous and local ecological knowledge often contribute to the development of restorative agricultural practices and can enhance resilience against climate change and reduce land misuse (Moyer, 2020).
Tune into our Wilde Capital Management ESG Week podcast: Day 1 – Regenerative Agriculture to learn more. In this interview with Marc Ian Barasch, author and filmmaker, we discuss the ideas behind applying regenerative principles to the business of agriculture, providing for greater abundance for a population of nearly 8 billion people, caring for climate, water, and other systems that are failing as we speak.
