All nations need to make major cuts to fossil fuel emissions and transition to a low-carbon economy, if we are to have any chance of achieving the aim of reducing global temperatures to 1.5 degrees above pre-industrial levels. This continues to be the message from the UN but, with so many countries suffering as a result of more frequent extreme weather events, that are threatening food security and global stability, more urgent measures need to be taken, to help countries to adapt to an increasingly hostile planet. Here are five tried and tested ways that nations can become more resilient, in the face of climate change.
1 Early warning systems
Research shows that a 24-hour warning of an oncoming heatwave or storm can reduce the subsequent damage by 30 per cent. Early warning systems that provide climate forecasts are one of the most cost-effective adaptation measures, yielding around nine dollars of total benefits for every dollar invested.
2 Ecosystem Restoration
The UN Decade on Ecosystem Restoration launched by the UN Environment Programme (UNEP) and partners in 2021 triggered a global movement to restore the world’s ecosystems. This global restoration effort will not only absorb carbon but also increase ‘ecosystem services’ to defend the world from its most devastating impacts.
3 Climate-resilient infrastructure
Climate-resilient infrastructure refers to assets and systems such as roads, bridges, and power lines that can withstand shocks from extreme climate impacts. Infrastructure is responsible for 88 per cent of the forecasted costs of adapting to climate change.
4 Water supplies and security
The story of climate change is, in many ways, a story about water, whether it is floods, droughts, rising sea levels, or even wildfires. By 2030, one-in-two people are expected to face severe water shortages.
5 Long-term planning
Climate adaptation solutions are more effective if integrated into long-term strategies and policies. National Adaptation Plans are a crucial governance mechanism for countries to plan for the future and strategically prioritize adaptation needs.
