How can we better understand and manage the impacts of droughts

View full report

Semi-arid regions of the world are often thought of as being particularly vulnerable to climate change. They are already climatically stressed with high temperatures, low rainfall and long dry seasons. Semi-arid ecosystems are highly dynamic, with bursts of productivity in the wet season and in good years, and very low productivity in dry years, often leading to temporary or longer-term land degradation.

Traditionally, inhabitants of semi-arid areas managed this variability in natural resource availability though pastoralism or agro-pastoralism. Nowadays, population growth, land-ownership issues, national borders and competition with other land-uses has reduced the opportunities for people to respond in traditional ways to the ecosystem dynamics of these systems, and has resulted in many instances of enhanced vulnerability to climatic variability.

It is clear that drought is already affecting many parts of the system in semi-arid regions, and climate change is likely to make drought events more frequent. Therefore, it is critical to assess the viability of scaling up successful local solutions to this challenge, and to identify new solutions. Importantly, this needs to be done in a participatory manner, with researchers and practitioners working alongside local stakeholders, local government and non-governmental organisations (NGOs).
