=== FAQ 5.2: How will climate change impact food availability by mid and late century and who will suffer most? ===

<div id="h2-74-siblings" class="h2-siblings"></div>

''Climate change impacts will worsen over time, with the period after mid-century seeing more rapid growth in negative impact than in the early part of this century. The impacts will be global, but people with fewer resources, and those who live in regions where impacts will worsen more rapidly, will be hurt the most.''

Climate change impacts will worsen over time, but the extent depends on how rapidly greenhouse-gas emissions grow. If the current rate of emissions continues, the impacts will worsen, especially after mid-century, with rapid growth in the number and severity of extreme weather events. Yields of plants, animals and aquaculture will decline in most places, and marine and inland fisheries will suffer. Food production in some regions will become impossible, either because the crops or livestock there cannot survive in the new climatic conditions, or it is too hot and humid for farm workers to be in the fields.

After harvest, agricultural production passes through the agricultural value chain, supplying animal feeds, industrial uses and international markets, with some stored for use in the future. Each of these transitions will be affected by climate change. Food storage facilities will face more challenges in dealing with spoilage. Transportation of perishable fruits, vegetables and meats will become costlier to maintain quality. Households and food services will need to spend more on food preservation.

Low-income countries and poor people are at higher risk, as they have limited social safety nets and suffer more from rising food prices and an unstable food supply. But large famers will also be hurt. Rural communities, especially smallholder farmers, pastoralists and fishers, are extremely vulnerable because their livelihoods mainly depend on their production. The urban poor will have to spend more on food.

A flood, for example, may force low-income families out of their homes, affect their employment and reduce their access to food supplies, with prices often rising after natural disasters. Families will have less access to safe water supplies, and this combination of lower food supplies, uncertain employment, displacement from home and rising food costs will increase the number of children who are undernourished.
