The majority of people in Nepal live in rural areas (88%). From the total energy requirements of the country, the rural areas account for 80%, mainly used for cooking. Almost all rural energy consumption (98%) is from traditional biomass resources, such as fuel wood, agricultural residues and animal dung. Accessibility to the electric grid by rural people is very limited, while LPG gas and kerosene oil in the high altitude and remote areas is relatively costly due to the high cost of
transport. Therefore, people living in remote areas depend heavily on forest resources to meet their demand for cooking energy.

In high altitude areas fuel wood is needed for cooking and space heating; the amount increasing with the altitude and colder temperatures. This results in continuous forest degradation, nutrient depletion from soils (by burning agro waste and cow dung), low agricultural outputs and soil
erosion. Together, these aspects result in a further reduction of accessibility to fuel wood.

Cooking Stove Improvements: Design for Remote High Altitude Areas Dolpa Region Nepal, Sjoerd Nienhuys April 2005

Metal and mud cooking stoves are analysed in Dolpa, a remote high altitude district in Nepal (over 2000m) where poor firewood efficiency of cooking stoves has been observed whilst the area is already largely deforested. Current metal or mud stoves have the air-intake above the firewood, lowering gas temperatures and causing incomplete combustion. More than 20 improvement options are presented in a table. These lead to higher burning temperatures, reduced firewood consumption and lesser soot development. Modifications have been made to lower manufacturing costs. The paper briefly explains the principles of the improvements and provides detailed sketches of the solutions. Improved cooking efficiency requires chopping of the firewood into
small pieces, but the additional time spent is balanced against the considerably less time spent in the collection of firewood. The prototype stove has been field-tested and modified several times to produce a model that is easy to manufacture and is acceptable to the villagers.

Honduras Microenterprise Project Stuart Conway, Trees, Water and People, December 2005

Hi Stovers,

Things are really taking off at our Honduras micro-enterprise project with AHDESA. We finally received the $25,000 from Rotary clubs and RI to spend on stove materials and for tools and equipment for the three metal shops - Ricardo Cruz, Marven Cordova, and Mario Nunez - Dona Justa's son. That had been holding back our production. Now, we will be able to produce 40 - 50 stoves/metal shop/month + the stove production from AHDESA's shop. AHDESA has had four TV interviews over the last month, and people are constantly calling or visiting the AHDESA office to look at or buy stoves. Suprisingly, the more expensive EcoHorno (Ecostove with oven) and the EcoTortillera (an EcoStove with a larger griddle) are more popular with the general public than the EcoStove so far. Sending a picture of the EcoStove production at the AHDESA shop/office.

Take care,

Stuart Conway
