My climate hero is a local artisan who sells energy efficient cook stoves. They consist of a metal casing with a ceramic lining that helps to direct 25 to 40 percent of the heat from a fire to a cooking pot.  80% of the energy used by a typical Tanzanian household is for daily cooking and lighting, the main sources of which are wood and charcoal. The indoor air pollution that results from the inefficient combustion of these materials is responsible for 1.5 million deaths per year globally, primarily among women and young children. Low-income households can spend up to 10% of their income on energy services, primarily for cooking. Finally, up to 500,000 hectares are deforested in Tanzania each year; to which the consumption of wood for fuel may contribute. By the way: my favorite dish is ugali and boiled goat meat. Ugali is made with maize flour. The world bank said in the year 2002: More than 80% of the population of Tanzania relies directly on agriculture for their livelihoods; a 10% reduction in rainfall would in effect make most of Tanzania unsuitable for Maize.
