Climate, Water, and Agriculture
研究了美国地表水取水量对农场价值的影响，发现灌溉可帮助农业适应全球变暖，其中滴灌系统能补偿高温。
<i>This study explores the interaction between climate, water, and agriculture. We test whether surface water withdrawal can help explain the variation of farm values across the United States and whether adding these variables to the standard Ricardian model changes the measured climate sensitivity of agriculture. The paper finds that the value of irrigated cropland is not sensitive to precipitation and increases in value with temperature. Finally, the paper finds that sprinkler systems are used primarily in wet cool sites, whereas gravity and especially drip systems help compensate for higher temperatures. These results indicate that irrigation can help agriculture adapt to global warming.</i>
