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

This ACT publication addresses the "perfect storm" gathering at the nexus of water, food, energy and biodiversity and proposes pathways to solutions.

Global demand for the water, food and energy is increasing due to population growth and rising per capita incomes in developing countries, with steadily worsening consequences for biodiversity and ecosystems. 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 produced by ACT and authored by two senior ACT advisers, former BC Deputy Minister Dr. Jon O’Riordan (author of ACT’s Biodiversity report) and international water expert Bob Sandford (author of ACT’s Water Governance report), outlines these challenges and offers a pathway to resolving them.
