The oldest form of renewable energy, hydroelectric power, is not immune to the effects of climate change. Its history is intertwined with the construction of large dams, which have significantly altered numerous river ecosystems worldwide. Additionally, smaller hydropower plants are vital in fostering development in rural regions that are distant from significant energy distribution hubs.
The water crisis currently unfolding in northeastern Spain is unlike anything seen in the past century. It sheds light on various shortcomings in water management practices prevalent in numerous arid regions of the developed world grappling with the changing climate. Catalonia's water issues provide valuable insights, offering an opportunity to devise effective solutions that can serve as a reference point.
Rising sea levels are leading to the first forced and planned population relocations. Small coral islands and tropical deltas face the most significant impact and are in imminent danger. In addition to mitigating measures, urgent and unavoidable adaptive solutions need to be considered.
Oases are ecosystems that have significantly shaped human history. They have been instrumental in the growth of human settlements, fostering cultural connections, and facilitating trade. They are a remarkable example of how water can give rise to ecosystems in arid environments. We must preserve them to perpetuate the valuable lessons they offer.
Many parts of the world experience the paradox of being surrounded by water yet unable to utilize it. In the Mexican state of Chiapas, this predicament is intensified by the deterioration of water supply facilities, along with a distressing decline in forest cover and biodiversity. A new project helps us to combat this challenge that threatens the balance of the planet.
The gap between available water and the water required to meet human needs is increasing every year. A shift in the way we handle water storage is therefore needed. It should encompass all available water sources, withstand the impacts of climate change, and ensure efficient management for the greater good. Embracing such an approach stands as the most effective assurance for achieving water security.
Nowhere is the vulnerability caused by the lack of access to water more evident than in Africa. It is a source of dispute and violence but also of hopeful alliances to face a future of stability and sustainable development, far from the pressing need to migrate. Achieving gender equality is another fundamental driver for achieving this.
Environmental psychology is emerging as a critical science for addressing climate change. The physical tipping points that we are crossing on a planetary scale cause changes in human behavior that may also be of no return. Successful adaptation to the new climate depends on avoiding them.
