Flooding could impact food security for more than 5.6 million people across multiple African nations, a new study has found. While these impacts are usually negative, the researchers also ...
Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type (i.e. flood control) and of the non ...
Similarly, household food security is considered to exist when all the members of a family, at all times, have access to enough food for an active, healthy life. [1] Individuals who are food-secure do not live in hunger or fear of starvation. [2] Food security includes resilience to future disruptions of food supply.
There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security.Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding. [5]
The flooding of farmland has added to concerns about the potential impacts on food security in the world’s second largest economy, as extreme weather events linked to climate change pose rising ...
Land degradation reduces agricultural productivity, leads to biodiversity loss, and can reduce food security as well as water security. [3] [1] It was estimated in 2007 that up to 40% of the world's agricultural land is seriously degraded, [4] with the United Nations estimating that the global economy could lose $23 trillion by 2050 through ...
In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and subsequently recovering. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil ...
Surface water flooding is especially dangerous for cities with a high proportion of impervious soil coverage and hard surfaces—such as roads and parking lots—that prevent rainwater from being ...
