Agriculture is an essential, politically charged source of economic growth, the primary livelihood for billions of the world's poor, a disproportionate target for government spending, and an irreplaceable source of food and nutrition. It has come to occupy more than ¼ of the earth's surface, wholly transforming the very natural systems on which it relies including biodiversity, hydrologic cycles, nutrient flows, and climatic conditions. Meanwhile, demand for food is projected to double by 2050, posing substantial challenges and opportunities at the intersection of agriculture and the environment. The course is designed to enable students to become informed consumers of cutting edge research, policies and business practices for balancing agricultural production with environmental protection. Specific topics explored will include climate change impacts, adaptation, and mitigation, deforestation, changing demand for agricultural products, determinants of agricultural productivity, and political and economic dimensions of agricultural development. The course will entail lecture, discussion, student-led discussion, problem sets, and a group policy memo. Prerequisites are E211 and E213 or equivalent with consent of the instructor.
