Synopsis (short abstract) Biochar, derived from the pyrolysis of organic materials, is a decomposure-resistant soil amendment that enhances fertility, boosts agricultural productivity, and sequesters carbon in the soil for thousands of years. Its positive effects include improved nutrient availability, increased pH, and enhanced water retention capacity. Biochar can reduce nutrient losses, improve soil health, and mitigate greenhouse gas emissions. While its effectiveness may vary, targeted application could be a promising strategy, taking into account factors such as soil type and specific environmental conditions.

Biochar opportunities: Building soil resilience while reducing wildfire, insects and diseases
XV World Forestry Congress, 2-6 May 2022

More than two-thirds of the worlds’ soils have been degraded through the loss of soil organic matter and risk losing productivity. When soil organic matter is low, ecosystems are at risk for drought stress, wildfire risk, or insect and disease infestations. Therefore, restoring soils by adding carbon- rich materials such as biochar can boost soil carbon and increase both soil and ecosystem health. increased soil stewardship can reduce carbon emissions by at least 5.5 gigatons of CO2 per year (15% of or current annual emissions) and healthy soils are able to hold more water and nutrients, reduce soil compaction, decrease invasive species, and promote microbial diversity. Biochar can benefit forest, range, mine, and agricultural soils and can be a carbon game-changer to mitigate climate change. Forest restoration activities that reduce standing tree volume through small diameter thinning operations produce large volumes of low (or no) value woody residues that can be converted to biochar on-site or at centralized processing facilities. In addition, higher value biochar could be transported to local farmers to build agricultural soil carbon for greater crop productivity and food security or used in livestock pens to reduce leaching and runoff while producing a high- value fertilizer. This paper will discuss forest managements’ role in reducing wildfire, insect, and disease risk and the contributions of biochar to soil health and resilience.

Recarbonization of global soils - A tool to support the implementation of the Koronivia Joint Work on Agriculture 2019

Also available in:

The implementation of proven Soil Organic Carbon (SOC)-centred Sustainable Soil Management (SSM) practices for maintaining carbon rich soils (peatlands, black soils, permafrost, etc.) and for sequestering more carbon in soils with such potential (croplands and degraded soils), would address the challenge of compensating global greenhouse gas (GHG) emissions. Soil organic carbon sequestration has been shown to hold the largest sink potential in terrestrial ecosystems and agroecosystems. SOC-centred SSM practices could not only mitigate GHGs emissions but also provides multiple benefits such as enhancing food security and farm income, reducing poverty and malnutrition, providing essential ecosystem services (climate and hydrological regulation, biodiversity maintenance, and nutrient cycling, among others), contributing to the achievement of the Sustainable Development Goals (SDGs) and building resilience to extreme climatic events. RECSOIL is designed to address the key challenges humanity faces today within an enabling framework integrated by a series of institutions and commitments related to climate change and sustainability. The main objective of the programme is to support and improve the national and regional GHG mitigation and carbon sequestration initiatives.

Soils, where food begins: how can soils continue to sustain the growing need for food production in the current fertilizer crisis?
ITPS Soil Letters #6
2023

Also available in:

No results found.

Soils are directly and indirectly involved in the provision of most ecosystem services vital for humans, including food production, which is fundamental for food security and sovereignty. Soils are the basis for producing more than 95 percent of our food. However, one-third of the world’s soils are degraded to some extent due to erosion, loss of organic carbon and biodiversity, salinization, acidification, compaction, and nutrient imbalance, among other causes. This ITPS Soil Letters reflects on the close link between soil degrading processes and fertility loss and proposes a portfolio of solutions focused on soil health with the ultimate goal of achieving food security.
