How does drought affect agriculture?
Below-average precipitation along with diminished surface water and groundwater supplies can reduce crop yields and affect irrigation and livestock watering. Above-average temperatures, which are also associated with droughts, can impose additional stress on crops and animals. These hydrologic and biophysical impacts, in turn, can lead to decreases in crop and livestock sales, increases in production costs, or both . Crop and animal scientists have studied the biophysical impacts of drought on crops for many years. Yet only a few studies estimate the economic cost of droughts to the agricultural sector—which is especially important as societies try to understand and account for the expected damages from climate change. To help fill this gap, researchers from RFF, the University of New Mexico, and Johns Hopkins University recently looked at how much crop yield is reduced by “incremental drought,” or an additional week of drought in any given year.

How much does drought affect crop yield?
We found that each additional week of drought in non-irrigated counties is associated with crop yield reductions in the range of 0.1 to 1.2 percent, on average. While this may seem like a small impact, one should keep in mind that these crop yield reductions are for one week of drought, and since most drought events last several weeks, the impacts can add up. Impacts in irrigated counties are smaller in magnitude, ranging from 0.1 to 0.5 percent for each additional week of drought. A focus on specific regions of the country found highly variable results. Some regions experience no yield impacts from drought, while yield reductions in non-irrigated counties in the Midwest are as high as 8.0 percent for corn and 3.1 percent for soybeans for every additional week of exceptional drought.

How does drip irrigation work?
Drip irrigation systems distribute water through a network of valves, pipes and tubes, bringing it directly to the plants’ roots and avoiding evaporation. They can reduce water consumption by up to 60 percent. Tillage, in turn, leads to more evaporation and lets more soil dry out at the surface, which is why less tillage saves water. As weeds can thrive with no tillage, this practice has to be combined with proper weed management measures.

Other possible changes that conserve soil moisture include the use of mulches and amendments and planting cover crops in the winter. As drought continues, farmers are also motivated to switch to drought-resistant crops such as sorghum. References. NSW Government: Cattle – Drought Management.
How do farmers manage water resources?
In time of drought, water shortages and economic restraints often drive farmers to improve their stewardship of water resources. For example, they use more efficient watering methods, such as drip irrigation. They schedule their watering based on actual crop needs by monitoring the soil and weather forecasts carefully. They use recycled water — for example, treated city waste water. Other possible changes that conserve soil moisture include the use of mulches and amendments and planting cover crops in the winter. As drought continues, farmers are also motivated to switch to drought-resistant crops such as sorghum.
Why does drought increase the risk of fire on a farm?
