Not enough rain? Too much rain? Weather alone cannot explain droughts and floods
Communities all over the world have suffered some of the most brutal effects of drought and flooding this year. Flash floods in western Europe, eastern and central Asia and southern African. And catastrophic drought in Australia, southern Africa, southern Asia, much of Latin America, western North America and Siberia are cases in point. The impacts extend well beyond the individual events. For example, the rise in food insecurity in the southern African region and unprecedented wildfires in North America, Europe and Central Asia.
What is going on? This is much more than bad weather in some cases, and is increasingly so.
The UNCCD organized an event at COP26, the Climate Change Conference taking place in Glasgow, United Kingdom, to focus attention on the land-water-climate nexus. The science and policy responses discussed make it clear that human decisions exacerbated by climate change are significantly – and arguably, catastrophically – amplifying the impact of drought and floods.
The discussion encouraged more strategic land use decisions. Decisions that ensure what we do where, and in particular, what we plant where, mitigatesthe impacts of both extremes, be it too much or too little rainfall. It also shed light on how important it is to have healthy soils. Soils that are replete with organic matter will obtain “more crop per drop”, and reduce the risks associated with drought and flooding.
Extreme events, including both droughts and floods are on the rise. With more land projected to be get drier and more and more people living in drylandsin the future, the discussions centered on the shift more than 60 countries are making from “reactive” response to droughts and floods to “proactive” planning and risk management designed to build resilience. Participants from Malawi, Pakistan, Honduras, Grenada and Burkina Faso provided concrete examples of policy alignment and cross-sectorial approaches to implementation. Here is a quick overview of the highlights.
