Global climate models predict increases over time in average temperature worldwide, with significant impacts on local patterns of temperature and precipitation. The extent to which such changes present a risk to food supplies, farmer livelihoods, and rural communities depends in part on the...

China is perhaps the most prominent example of a developing country that has transitioned from taxing to supporting agriculture. In recent years, Chinese price supports and subsidies have risen at an accelerating pace after they were linked to rising production costs. Per-acre subsidy payments...

Reciprocal trade agreements (RTAs), which grant special preferences to members, affect the pattern and volume of bilateral trade in global markets. This study uses the gravity framework and panel data depicting annual trade between 69 countries over 31 years to examine how 11 RTAs have shaped...

Since the late 1980s, multilateral and bilateral trade agreements have reduced tariff rates and worked to restrain the arbitrary use of nontariff measures, including sanitary and phytosanitary regulations. U.S. imports of fruits and vegetables have risen steadily during this period as more...

A partial-equilibrium, multiple-commodity, multiregion model of agricultural policy and trade is used to simulate the effects of changes in domestic and trade policy on dairy production, consumption, prices, and trade. Simulations using the ERS-Penn State Trade model analyze the effects of...

Animal waste from confined animal feeding operations is a potential source of air and water quality degradation from evaporation of gases, runoff to surface water, and leaching to ground water. This report assesses the potential economic and environmental tradeoffs between water quality policies...

This report examines evidence on the relationship between agricultural land-use changes, soil productivity, and indicators of environmental sensitivity. If cropland that shifts in and out of production is less productive and more environmentally sensitive than other cropland, policy-induced...

Nitrogen is an important agricultural input that is critical for crop production. However, the introduction of large amounts of nitrogen into the environment has a number of undesirable impacts on water, terrestrial, and atmospheric resources. This report explores the use of nitrogen in U.S....

The Energy Independence and Security Act (EISA) of 2007 established specific targets for the production of biofuel in the United States. Until advanced technologies become commercially viable, meeting these targets will increase demand for traditional agricultural commodities used to produce...
