1. The Dust Bowl (1931-1939).

1. The apex came in 1934, which NASA researchers recently called the worst drought year of the last millennium in North America. Not far behind was 1936, when, amid the dust storms, a devastating summer heat wave killed upwards of 5,000 Americans and 1,100 Canadians.

1. Human activity can directly trigger exacerbating factors such as over farming, excessive irrigation, deforestation, and erosion adversely impact the ability of the land to capture and hold water.

2. As the soil becomes drier, it is vulnerable to erosion. This process can lead to fertile land becoming desert-like, a process known as desertification.

1. Due to drought, less food, water, and cover will be available. Less food will likely result in reduced reproduction by adult animals. Less food for adults will also result in less food available for young wildlife, such as the production of milk by deer and elk.

2. Indicators, which are used to describe drought conditions, are variables such as precipitation, temperature, streamflow, ground and reservoir water levels, soil moisture, and snowpack.

3. Drought can reduce the 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.

4. Put used domestic water to use by watering grasses and plants. Avoid using a handheld hose for any domestic chores. Use a bucket instead of a shower for bathing. Do not engage in deforestation.

5. Human activity can directly trigger exacerbating factors such as over farming, excessive irrigation, deforestation, and erosion adversely impact the ability of the land to capture and hold water.

6. Replace as much of the grass ( an invasive and water-needy species) with drought tolerant native species.
