This document discusses the use of biochar in developing countries for sustainability purposes. It summarizes that biochar can be produced from various biomass feedstocks using different technologies. When integrated into traditional agricultural practices through a concept called "biocharculture", biochar can help developing countries adapt to climate change by increasing soil fertility and crop yields, sequestering carbon, reducing emissions and conserving water. Biochar has many environmental, economic and social benefits and aligns with the principles of sustainable agriculture.
