Impact of Climate Change
Water held underground in soil or between rocks makes up the world’s largest source of freshwater and is relied on by many families in Africa. Increased temperatures under the changing climate cause increase in evaporation rate which leads to reduced surface flow and less water available for aquifer replenishment. For this reason, Chomuzangari women want to be at the forefront in planting trees that help the flow of water in the sky. Trees are fountains, sucking water out of the ground through their roots and releasing water vapor into the atmosphere through pores in foliage. In their billions, they create giant rivers of water in the air, rivers that form clouds and create rainfall hundreds or even thousands of miles away. Currently, there is a lot of cutting down of trees in Zimbabwe without replenishing them. A major project of tree planting is what rural Zimbabwe needs right now.
According to FAO, climate change will affect all four dimensions of food security: food availability, food accessibility, food utilization and food systems stability. It will have an impact on human health, livelihood assets, food production and distribution channels, as well as changing purchasing power and market flows. Its impacts will be both short term, resulting from more frequent and more intense extreme weather events, and long term, caused by changing temperatures and precipitation patterns. (fao.org)
