For that purpose, success stories presented in the Fair provide excellent examples of the key drivers that lead to successful innovation, without neglecting the obstacles and challenges that had to be faced and overcome before the innovations were brought into use. A drought is an event of prolonged shortages in the water supply, whether atmospheric (below-average precipitation), surface water or ground water.A drought can last for months or years, or may be declared after as few as 15 days. The drought affected the production of livestock and field crops such as wheat, corn, and soybean production in the Great Plains and Midwest and accounted for $14.5 billion in loss payments by the federal crop insurance program. Compared with the other three methods, the physical concept of drought vulnerability assessment model based on entropy fuzzy pattern recognition is more obvious, and the evaluation results are reasonable and credible. For example, the 2012 drought affected livestock, corn, and soybean producers of the High Plains and Midwest regions. In the case of rain-fed agriculture, severe droughts may directly reduce or eliminate yields, resulting in crop failure and nutritional and revenue deficits. For example, Pablos et al. For example, in Uruguay in 1988-89, drought . Sustained drought has considerable negative effects on crops and livestock, including the reduced production, destruction of property, and livestock sell-offs.

In 2015, farms contributed, For example, in 2012, severe drought impacted 80 percent of agricultural land in the United States, causing more than two-thirds of its counties to be declared disaster areas. Drought is an insidious hazard of nature. It originates from a deficiency of precipitation that results in a water shortage for some activity or some group. From the global version of ASIS, which was designed to detect agricultural hot spots on the globe, standalone versions can be developed to monitor agricultural drought at country or regional level. Agriculture Canada estimated in September that 2021 canola production was 12.8 million metric tons, the lowest in 13 years. Drought in the environment; The effects of drought; Approaches to drought relief. • 37,44% settlements in South Africa are affected by drought • Real agricultural output was 9.2% lower in the first half of 2019 than in the corresponding period of 2018. When available water supplies are unable to meet the needs of crops or livestock at a particular time, agricultural drought may ensue. For example, less precipitation can result in decline of soil moisture immediately with potential onset of agricultural drought. Mexico's previous extreme droughts, in 1996 and 2011, caused major . And the latter two were the main objects of regulation and control. The extent of this drought was massive, reaching from British Columbia across Canada to the Atlantic provinces and also farther northward than other major droughts.

Recent empirical and theoretical studies sug-gest that the presence of extreme nonlinearity and thresholds in water availability or other environmental variables may This creates a water shortage that damages crops, livestock, and the environment. Additionally, the drought extremity we are experiencing this year correlates with the severity of wildfires, since drought is an important contributing factor to the dry conditions necessary for wildfire to spread to the levels we see today. In addition, surface and groundwater supplies may decline during drought, affecting water availability and increasing costs to access water for crop or forage irrigation and watering livestock. Drought early warning systems are vital for the agricultural sector to prepare for this variability, strengthening its resilience to drought. Drought can have serious impacts on local economies and agricultural production (Ghulam et al. The site is secure. In California, for example, . Reference Ghulam, Qin, Kusky and Li 2008).There have been many regional drying trends worldwide over the last three decades (Reference Dai Dai, in press), and many world regions have suffered from water crises (Ghulam et al.Reference Ghulam, Qin, Kusky and Li 2008). For example, during the 1938-39 season, a drought existed from 11 to 22 January. Regionally, crop production is also facing severe challenges due to drought, and there's no better example than Pinal County, located in the heart of central Arizona.

Bridging finance for affected farmers to manage down in the repayment of agriculture debt 7. By intensity, droughts are Other agriculture- and food-related sectors contributed an additional $855 billion and accounted for 21 million full- and part-time jobs. The Palmer Drought Severity Index (PDSI, Palmer, and 196 X) and other soil moisture drought indices are good representatives of drought in non-irrigated agricultural regions. Found inside – Page 302In addition, many methods were also proposed to monitor agricultural drought. For example, Lessel et al. presented a method based on quasi-climatological anomalies of remotely sensed data to monitor agricultural drought [17]. Agricultural drought was highlighted as a severe hazard based on early findings from the EU's Instrument for Stability and Peace for Resilience building in the Sea of . 2. Depending on seasons, droughts are classified as spring, summer, or autumn. For example, in 2012, severe drought impacted 80 percent of agricultural land in the United States, causing more than two-thirds of its counties to be declared disaster areas. Drought can be one of the costliest natural disasters to affect an area. (iii) Definition of theoretical causal relationships between the agricultural variables and drought. Drought can also contribute to insect outbreaks, increases in wildfire and altered rates of carbon, nutrient, and water cycling—all of which can impact agricultural production, critical ecosystem functions that underpin agricultural systems, and the livelihoods and health of farming communities. For example, in the Tibetan Plateau region, both temperature and solar radiation are important factors that may affect agricultural drought by modulating evapotranspiration (while in southern regions agricultural drought is more sensitive to precipitation) (Zhou et al., 2021).
