Uncharted Waters ― The New Economics of Water Scarcity and Variability

The 21st century will witness the collision of two powerful forces - burgeoning population growth, together with a changing climate. With population growth, water scarcity will proliferate to new areas across the globe. And with climate change, rainfall will become more fickle, with longer and deeper periods of droughts and deluges. This report presents new evidence to advance understanding on how rainfall shocks coupled with water scarcity, impacts farms, firms, and families. On farms, the largest consumers of water in the world, impacts are channeled from declining yields to changing landscapes. In cities, water extremes especially when combined with unreliable infrastructure can stall firm production, sales, and revenue. At the center of this are families, who feel the impacts of this uncertainty on their incomes, jobs, and long-term health and welfare. Although a rainfall shock may be fleeting, its consequences can become permanent and shape the destiny of those who experience it.Pursuing business as usual will lead many countries down a 'parched path' where droughts shape destinies. Avoiding this misery in slow motion will call for fundamental changes to water policy around the globe. Building resilience to rainfall variability will require using different policy instruments to address the multifaceted nature of water. A key message of this report is that water has multiple economic attributes, each of which entail distinct policy responses. If water is not managed more prudently--from source, to tap, and back to source--the crises observed today will become the catastrophes of tomorrow.

The World Bank came into formal existence in 1945 following the international ratification of the Bretton Woods agreements. It is a vital source of financial and technical assistance to developing countries around the world. The organization's activities are focused on education, health, agriculture and rural development, environmental protection, establishing and enforcing regulations, infrastructure development, governance and legal institutions development. The World Bank is made up of two unique development institutions owned by its 185 Member Countries. The International Bank for Reconstruction and Development (IBRD) focuses on middle income and creditworthy poor countries and the International Development Association (IDA), which focuses on the poorest countries in the world.
