-This paper presents the extension of a sustainable water purification project conducted by engineering students from a university in South Africa and a university in the United States. Through collaboration with faculty at both universities and a community in rural South Africa, the student team facilitated the repair of a water filtration system installed the previous year. While the team had the specific goal to repair the system, they entered into this commitment with an open-ended approach to problem solving that drew heavily on community engagement and participation. The following paper describes the technical details of the project and the process by which the community was enabled to take the lead in the assessment, design and implementation of a sustainable repair to their water filtration system.

Land use change in the form of deforestation and degradation is contributing to the release of greenhouse gases on the order of 1.2 ±0.7 Gt CO 2 e per year. Emissions of this magnitude suggest that the conversion and disturbance of forests play a significant role in forcing global climate change. Although there is growing recognition of this contribution among scientific and political communities, there is an expressed need for more efficient and accurate methods for assessing the role of forests in shifting climate patterns. Recent efforts to measure and monitor forests on large scales have used remotely sensed data from airborne and spaceborne sensors. This study leverages high spatial resolution remotely sensed data with in-situ field measurements to measure forest structure in the Dry Deciduous Lowland Forests ofMozambique. The approach to analysis was motivated by the importance of three-dimensional forest structure in driving forest dynamics. A novel tree crown analysis methodology was employed in order to calculate select structural properties of forests from remotely sensed data.
