Agriculture is one of the most important activities on earth because we all need food to stay alive. Some critics are concerned about our capacity to satisfy global demand for food in the coming decades because of the significant expected increase in world population and threats caused by climatic variability and climate change. Others are more optimistic because they believe technological progress will be the answer, as is often shown by historical data. Independent of what causes climatic variability and climate change, there is evidence of observed changes in temperature and precipitation patterns. Thus, this study identifies and analyzes the drivers of agricultural productivity and investigates the impact of climatic variability on production and productivity across the Southern United States. The study is focused on the 16 states in the southern United States, as defined by the US Census Bureau, because of the role they play in US and world agriculture. We use data from the Economic Research Service (ERS) of the United States Department of Agriculture (USDA), the National Climatic Data Center (NCDC) of the National Oceanic and Atmospheric Administration (NOAA) and the US Geological Survey to estimate several stochastic production frontier (SPF) model specifications. The estimated parameters are then analyzed and used to compute and decompose Climate Adjusted Total Factor Productivity (CATFP) into several measures of efficiency. Results show that agricultural production in the southern United States is more responsive to labor and has been increasing at a 1.13 percent rate annually. The findings also suggest that while precipitation, on average, has a positive and significant impact on productivity, intra-annual variation in both temperature and precipitation, has a negative and significant impact on production. The impact of climatic effects on productivity was mixed. Technological progress has been the main driver of agricultural productivity, and all the states displayed a negative rate of technical efficiency, except for West Virginia. These results highlight the importance of investing in research and development (R&D), which has been identified as the engine of technological progress, and also suggest that more federal, state and local funding, for extension programs to increase technical efficiency and adoption of best management practices, is needed. Investments in R&D should also be oriented towards seeds and crops that are more resilient to climatic variability because its impacts are, overall, negative and significant on production.
