Risk of food shortages to rise with climate change Biology Diagrams Climate change's physical effects on the food chain, particularly those influencing nutrition and foodborne infections, may also have an influence on human health. During moderate drought, 108 food-producing plant species were available. In extreme drought, only 56 edible plant species will be available for consumption. (Fedick and As an indicator of a city's resilience to drought-related food shock, we used food supply chain diversity (SCD), since SCD is inversely and strongly related to the probability of experiencing a food shock for U.S. cities . Further, we combined hazard potential (as measured by SCE) with mitigation (as measured by SCD) to quantify the risk of 2022 was a year that broke many records in terms of extreme heat and drought conditions around the world, putting the food sector at stake. A recent report (5) states that the current winter drought in Europe comes after an unusual hot and dry summer, when crop yields dropped by a lot (4).

Compound natural and human disasters: Managing drought and COVID Biology Diagrams
The negative effects of drought on plant growth and yield are also linked to the negative effects of low soil moisture on the soil microbiome (Nguyen et al., livestock, the physical infrastructure of agriculture, and the food supply chain, reducing agricultural productivity and food availability (Atanga and Tankpa, 2021). In addition,
The market share of supermarkets and food delivery systems is likely to increase, with the net effect being a modernization of agri-food supply chains. Drought is mostly local, affecting farmers upstream and their associated intermediaries and farmworkers, which means that wholesalers and retailers linked to the global market, may obtain supply Disruptions in the food supply chain are events that affect the flow of products and can be caused by extreme weather, natural disasters, conflicts, pandemics, and political situations, among others. Coffel et al. [18] analysed the effect of drought on food production in the Upper Nile basin in areas such as Ethiopia, Sudan, and Uganda. Drought triggered widespread losses of species and links, with larger taxa and those that were rare for their size, many of which were predatory, being especially vulnerable. Many network properties, including size-scaling relationships within food chains, changed in response to drought. Other properties, such as connectance, were unaffected.
