Governments of developing countries face the dual tasks of increasing agricultural productivity and ensuring sustainability of resources. The government of Ethiopia initiated a major rural development program in Tigray, Ethiopia ten years ago, called SAERT (Sustainable Agricultural and Environmental Rehabilitation), to change the decline in agricultural productivity and reverse local forest degradation. SAERT targets water resource development through the construction of regional public microdams, intended to bring irrigated agriculture to surrounding villages and improve household income. Through SAERT, villagers can choose to plant trees on public microdam sites, protected and monitored by the surrounding villages. Unfortunately, microdams may cause potentially serious side effects to human populations through water-borne illnesses such as malaria and schistosomiasis. This paper examines incentives for villagers in Tigray to plant trees for private use, in both villages with and without access to regional public microdams. In addition, we investigate the importance of health factors on the household decision to plant trees on household and public land. / Master of Science

Plants are the unique materials of landscape architecture, and, as any landscape architect will attest, the first question likely to be posed by a new acquaintance will be about a plant. Today's world offers landscape architects more and more opportunities and demands requiring a broad and thorough understanding of the unique characteristics of plants — to be plantsmen. Yet, the curricula of landscape architecture education programs nationwide are deficient in plant knowledge requirements, and by and large the state registration examinations for professional licensing do not include tests of plant knowledge. This thesis explores the idea that in addition to allowing the landscape architect to respond to those demands, plantsmanship also contributes positively beginning in the earliest stages of the design process when the landscape architect can represent plants in ways that allow him or her to cue into accumulated plant knowledge. / Master of Landscape Architecture
