Master's in Agricultural, Environmental, and Sustainability Sciences

The School of Earth, Environmental, and Marine Sciences offers a Master of Science (MS) in Agricultural, Environmental, and Sustainability Sciences (AESS). The AESS program provides students with a unique, integrative education and training experience that prepares them to meet the challenges and opportunities in the multiple dimensions of contemporary agricultural, environmental, and sustainability science disciplines. Specifically, the AESS program targets students wishing to pursue a graduate degree with the intention of entering the work force and contributing their expertise towards sustainable agriculture, stewardship of natural resources and ecosystem services, or the development of sustainable systems in general. This multidisciplinary degree program is designed to provide a rigorous applied and theoretical education in the natural and social sciences with emphasis on the causes and consequences of land use change and other anthropogenic and natural forces across Texas coastal watersheds and beyond. Students graduating from the program will be prepared to take on decision-making positions in a wide range of governmental agencies and NGOs. Students can expect a broad set of science careers, within and beyond academia, including private and public sector organizations concerned with agriculture, environmental conditions, or sustainability, or which recognize that food systems, watersheds, biodiversity, and functional ecosystems are fundamentally important to our societies.

Student learning outcomes: 1) Acquisition of a thorough understanding of watershed dynamics and human-natural productive ecosystems at various levels of organization. 2) Attain quantitative and qualitative data-interpretation skills that enable one to draw appropriate conclusions from raw experimental results, as well as from interpretation of primary literature. 3) Development of technical and intellectual skills needed to design, carry out, and interpret results of experiments addressing agricultural, environmental or sustainability problems, and do so by employing a wide range of multidisciplinary, state-of-the-art approaches. 4) Acquire verbal and written communication skills to needed to conduct professional discourse with experts within the focal disciplines, exchange scientific ideas between researchers of diverse backgrounds, and effectively communicate scientific information with a lay audience. 5) Develop and enhance existing critical thinking skills through hands-on problem solving.
