The Climate Nexus. Water, Food, Energy and Biodiversity in a Changing World

Secure supplies of water, food and energy are essential to human dignity and well-being around the globe. In turn, the vitality of these three depends on a thriving biodiversity supported by healthy ecosystems. The complex interdependence among these four factors is known as the Nexus. Global demand for the first three elements is increasing due to population growth and rising per capita incomes in developing countries, with steadily worsening consequences for the fourth of these elements.
The four Nexus elements are also coming under increasing pressure from climate disruption: more frequent and severe flooding and storms, droughts, extreme heat, and pest outbreaks. What's more, Nature's capacity to moderate these impacts is being steadily eroded by rapid, widespread land-use development and associated pollution. This impending "perfect storm" of increasing demand, decreasing supplies and rapidly changing hydro-climatic conditions throughout the Nexus requires transformative policy responses that encompass economy, equity, social justice, fairness and the environment.
This book outlines these challenges and offers a pathway to resolving them. Published to coincide with the United Nations Climate Change Conference being held in Paris, France, in December 2015, this latest RMB manifesto introduces readers to the serious and converging impacts of climate and weather on water, food and energy and on the biodiversity we cannot do without. Secure supplies of water, food and energy are essential to human dignity and well-being around the globe.
