Clean Cooking is essential to maintain a healthy lifestyle. However, many people in developing economies do not have access to clean cooking. To promote clean cooking, first, we need to understand the cooking patterns in the household, and second, design interventions over those patterns. We also need to understand the grid and power supply readine...

Background: Whether cooking with solid fuels, as occurs widely in developing countries, including Nepal, is a risk factor for pulmonary tuberculosis (PTB) is uncertain. Epidemiologic studies have produced variable results. This case-control study sought to resolve this issue with a large sample size and a population-based control group. Methods:...
Article
Background: Globally, solid fuels are used by about 3 billion people for cooking and a smaller number use kerosene. These fuels have been associated with acute lower respiratory infection (ALRI) in children. Previous work in Bhaktapur, Nepal, showed comparable relationships of biomass and kerosene cooking fuels with ALRI in young children, compare...

Through the “Maximizing the Health Benefits of Clean Household Energy in Peri-Urban Nepal” health demonstration project, CCA along with local and international partners spent the next two years exploring the best means of increasing access to and encouraging the use of clean fuels and technologies that meet local needs (i.e., electric, liquified petroleum gas (LPG), and biogas). Following 772 Nepali households for a full year, this project was designed to monitor the effectiveness of specific intervention activities aimed at increasing clean cooking practices and/or decreasing the use of traditional biomass stoves. These activities included increasing physical access (repairing biogas digesters and upgrading household electrical wiring to accommodate electric cooking) as well as behavioral, educational, and market strengthening programs. Two additional innovative community-based outreach activities were the use of female community health volunteers to support households in their energy transitions and a pilot conditional cash transfer program to encourage the disuse of traditional stoves.
