There are different ways to think about vulnerability to weather and climate events. Rising average temperatures, more extreme heat throughout the year, fewer sufficiently cool days during the winter, and more frequent cold-season thaws will likely affect farmers in all regions. A low vulnerability score does not mean a state is not (or will not) experience drought conditions. Drought is also one of the costliest weather-related disasters.

Answer: Droughts are worsening around the world, posing a great challenge to plants in all ecosystems, said Lawren Sack, a UCLA professor of ecology and evolutionary biology and senior author of the research. For instance, Oklahoma was ranked as the most vulnerable state due largely to its extensive cattle ranching and other agricultural enterprises, as well as limited possibilities for irrigation. The lack of adequate precipitation, either rain or snow, can cause reduced soil moisture or groundwater, diminished stream flow, crop damage, and a general water shortage. Typhoons, floods, earthquakes, hurricanes, tsunami and other extreme weather greatly affect one's country and status of life.

The lack ofprecipitationcan cause a variety of problems for local communities, including damage tocrops and a shortage of drinking water. The authors of the study published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS), however note that, while it is relatively easy to identify populations vulnerable to the climate impacts of, for instance, sea-level rise, not enough work has been done to identify populations vulnerable to the effects of drought on food availability and nutrition. 4182 13 A drought is a period of time when an area or region experiences below-normal precipitation. However, there is a link between drought and some climate patterns. During a drought, these water sources are diminished and may even dry up, preventing crops from being irrigated and causing them to die off. Scientists often study historical droughts to put modern-day droughts in perspective. Even if the overall water supply is low, drought is usually less of a concern in the winter months because demand is far less than in the summer. The SciLine service, 500 Women Scientists or the press offices of local universities may be able to connect you with local scientists who have expertise on drought in your area. So soils dry up quickly and cannot support growth of plants and crops and in the short term lead to agricultural droughts. Example:Wetlands, such as the Caroni Swamp, are sensitive to increasing salinity from sea water, and pollution from stormwater runoff containing agricultural chemicals, eroded soils, etc. Major population centers, especially those in areas of high seismicity, are highly vulnerable. One of the consequences of poor child nutrition is stuntingin other words, impaired growth and developmentwhich currently affects at least one in three children in these parts of the developing world.
