Ethiopia is wise to large-scale, high-impact actions on climate adaptation and mitigation through their soils, and they’re using that strategic resource. Storing soil carbon could help us achieve a more sustainable agricultural future for millions of American families now and for generations to come. Climate projections indicate that Ethiopia is facing an increasingly hotter and drier future. By 2070, temperatures can increase up to 2.2 °C, posing a risk to soil health and food security.
The anticipated rise in temperature and decreasing rainfall threaten to accelerate the decomposition of organic matter in the country’s soils. This landscape requires new ways of thinking to renew soil fertility and resilience, the foundational bedrock of sustained agricultural productivity. Researchers underscore that through enriching soils with organic matter, Ethiopia has the potential to regain at least some of its lost soil fertility.
The Importance of Regenerative Agriculture
In this effort, regenerative agriculture has become one of the key strategies in Ethiopia’s battle against climate change. This implementation adopts ICM practices like leaving crop residues on the field, applying organic manure, rotating with cover crops, and adopting agroforestry systems. These practices go a long way toward increasing carbon in the soil while boosting biodiversity and the dirt’s ability to hold water.
In the upper Abbay basin of Ethiopia, a team of researchers has been investigating the potential outcomes of various farming practices on soil health. Through this research they have developed eight distinct farming archetypes. These go from the conventional side of the spectrum all the way to highly regenerative practices, which include as much as 50% organic inputs. This research aims to provide insights into how different farming practices can influence soil carbon levels in the face of climate change.
The researchers used a complex computer model, known as RothC. They utilized it to model potential improvements on Ethiopia’s soils over the next 50 years. To create the most accurate picture possible, I calibrated the model using detailed data on the country’s soils, climate patterns, and crop types. Together, this method allows for a detailed assessment of how these elements work together. These results indicate that regenerative agricultural practices significantly improve soil health. Climate change can make these benefits much more limited or even impossible.
Climate Change Impacts on Soil Health
Ethiopia’s soils have experienced historical degradation from decades of tree cutting, removal of crop residue, and soil erosion. These factors combined have dramatically impacted the land’s ability to sequester carbon, as well as nurture strong, healthy plants. As climate change accelerates these problems, the need for successful mitigation strategies only grows more urgent.
Decades of scientific research on regenerative agriculture demonstrate the powerful benefits to the environment, economy and public health. Increasing temperatures and less rainfall can double those benefits. This harsh reality underscores the need to incorporate climate adaptation strategies into agricultural programs. These practices are key to improving the state of our nation’s soils. Their impact will be greatly limited if we fail to address the root causes of climate change.
Together, rising temperatures and reduced rainfall are a double burden for Ethiopia’s farmers and food security. The land represents the stakes for their livelihood that farmers cannot afford to lose. Considering this dependence, it is imperative that policymakers look to soil health as an important approach to climate adaptation and long-term agricultural sustainability.
Future Outlook for Ethiopian Agriculture
Ethiopia today faces a uniquely difficult set of confluences. It needs to increase agricultural output while adopting sustainable practices necessary to fight climate change. The research we recently completed in the upper Abbay basin reveals an important link. It illustrates how fuelling soil health can be a climate game changer — directly influencing climate’s dynamic. It further highlights the necessity of holistic approaches that include regenerative agriculture and go beyond it to adapt to the effects of climate change.
National and global efforts to restore soil health using regenerative practices should complement, not replace, ambitious policies and strategies to mitigate climate change. This means supporting reforestation initiatives, providing access to advanced water management infrastructure, and equipping farmers with agricultural education. Through better collaboration between government agencies, researchers, and Ethiopian farmers, Ethiopia has the chance to create and strengthen resilient agricultural systems. United, they’ll help to arm the sector against climate pressures.
