Wood fuels are used as an energy source for cooking, heating, and small-scale industrial activities by a large number of people in the developing world. As populations increase, the effects of burning wood or other biomass on the vitality of forests, air quality, and human health or well-being can be severe. This project investigates the dynamic connections among these areas of concern and evaluates strategies that can alleviate problems in the future. It examines how people use forest resources for energy and whether these habits are altered by the introduction of more efficient cooking stoves and other new technologies. The effects on forest condition will be examined through direct measurements and modeling. Measurements of air quality will determine how pollution levels will be affected. The field sites are in Malawi and the results will be scaled up to determine the possible changes in the larger regions of eastern and southern Africa. This research has the potential to improve forest condition and air quality in areas at risk of severely declining environmental conditions, and improve the quality of life for large numbers of people who depend upon these resources.The overall goal of this project is to investigate linkages between the use of biomass energy in Southern Africa and its coupled impacts on human, terrestrial, and atmospheric systems. Quantitative and qualitative field observations of both human and natural systems, scenario development, and modeling of both the atmospheric and land-use changes will further examine these linkages and quantify the magnitude of human influence. The project will explore how natural and human system resilience can be enhanced at local, national and regional scales assessing the impact of a scalable household energy intervention. This study couples both terrestrial and atmospheric systems with the human system, providing a new dimension on human-environment relationships. It also adds new insights into the relative effects of a wide array of biomass energy uses on land-use land-cover changes, air quality, and human well-being. The project also evaluates a scalable household energy intervention targeted at the poorest and most vulnerable households, and models its influence on terrestrial and atmospheric systems in future scenarios.

木材燃料被发展中国家的许多人用作烹饪、取暖和小规模工业活动的能源。随着人口的增加，燃烧木材或其他生物质对森林活力、空气质量和人类健康或福祉的影响可能是严重的。该项目调查这些关切领域之间的动态联系，并评估可在未来缓解问题的战略。它审查了人们如何使用森林资源作为能源，以及这些习惯是否因采用更高效的炉灶和其他新技术而改变。对森林状况的影响将通过直接测量和建模进行检查。对空气质量的测量将确定污染水平将受到何种影响。实地地点在马拉维，其结果将扩大，以确定东部和南部非洲更大区域可能发生的变化。这项研究有可能改善森林条件和空气质量的地区在严重下降的环境条件的风险，并提高生活质量的大量人谁依赖于这些资源，这个项目的总体目标是调查之间的联系在南部非洲的生物量能源的使用和其对人类，陆地和大气系统的耦合影响。对人类和自然系统进行定量和定性的实地观测、设想方案的制定以及对大气和土地使用变化进行建模，将进一步研究这些联系，并量化人类影响的程度。该项目将探讨如何在地方、国家和区域各级加强自然和人类系统的复原力，评估可扩展的家庭能源干预措施的影响。这项研究将陆地和大气系统与人类系统结合起来，为人类与环境的关系提供了一个新的维度。 它还增加了新的见解，对土地利用土地覆盖变化，空气质量和人类福祉的相对影响，广泛的生物质能源的使用。该项目还评估了针对最贫困和最脆弱家庭的可扩展家庭能源干预措施，并模拟了其对未来情景中陆地和大气系统的影响。
