Agricultural droughts can occur for various reasons, including low precipitation, the timing of water availability, decreased access to water supplies, or increased water demands from the sector. The U.S. Geological Survey (USGS) has many ongoing and recent water-related natural hazard activities in New England that can be used to help mitigate the effects of natural hazards in cooperation with other agencies.

Meteorological, when precipitation departs from the long-term normal; Agricultural, when there is insufficient soil moisture to meet the needs of a particular crop at a particular time. Agricultural drought is when agricultural activity is greatly impacted by drought. Drought can reduce both water availability and water quality necessary for productive farms, ranches, and grazing lands, resulting in significant negative direct and indirect economic impacts to the agricultural sector.
Nationwide losses from the U.S. drought of 1988 exceeded $40 billion, exceeding the losses caused by Hurricane Andrew in 1992, the Mississippi River floods of 1993, and the San Francisco earthquake in 1989. which cause continuous loss of water transpiration and evaporation.

Most farmers have already implemented emergency measures to limit the impact of the drought. Surface water quickly evaporates in warm, dry conditions leading to an increased risk of drought. Agricultural drought links various characteristics of meteorological (or hydrological) drought to agricultural impacts, focusing on precipitation shortages, differences between actual and potential evapotranspiration, soil water deficits, reduced groundwater or reservoir levels, and so forth. A drought is a period of drier-than-normal conditions that results in water-related problems.The amount of precipitation at a particular location varies from year to year, but over a period of years, the average amount is fairly constant.

Drought can reduce both water availability and water quality necessary for productive farms, ranches, and grazing lands, resulting in significant negative direct and indirect economic impacts to the agricultural sector. Irresponsible agricultural practices like the over-irrigation (depleting water resources) and over-farming (adversely impacting the soil quality) of land can often lead to droughts. Unfortunately, this is of little use as long as there is a lack of substantial rainfall. The herd will usually stay on these annual grasslands until mid-June, but this year Schohr brought the cattle home in mid-May.
