Environmental impacts at the local levelEnvironmental damage at the local level results from biomass harvesting for fuel purposes. Increased demand for fuel (e.g. through population growth) or reduced availability of fuel may add to deforestation and land degradation, and increase the risk of natural disasters, such as floods and landslides. Insufficient availability of fuel may also cause people to change to lower-grade fuels, such as dung and crop residues, depriving soil of its natural fertilizer to the detriment of agricultural production. Ultimately, these impacts on the local environment can have important health and economic implications. Some household energy and health interventions counter these effects by reducing the need for biomass fuel through higher energy efficiency (e.g. a fuel-efficient stove) or by eliminating the use of dung and wood altogether (e.g. switching to a cleaner fuel).
