Water Trading: An Emerging Solution to Water Scarcity

As climate change and population growth puts increasing pressure on water resources, water trading is emerging as an innovative solution to reallocate water to its highest valued uses. By allowing water rights to be traded between buyers and sellers, water trading aims to improve the efficiency of water allocation while also generating economic and environmental benefits. In this article, we will explore the concept of water trading, analyze some prominent water trading schemes currently operating around the world, and discuss some of the issues and opportunities associated with scaling up water trading globally.

What is Water Trading?

Water Trading refers to the practice of buying and selling water access rights between individual users or groups. It allows water to be transferred between agricultural, industrial and municipal users through market mechanisms. The basic principle is that water rights are unbundled from land ownership and trading of these rights is facilitated through water markets. These markets allow buyers and sellers to negotiate water transfers at mutually agreed prices. Some key aspects of water trading include:

– Water rights are legally defined and separated from land title, making them a tradable commodity.

– Buyers and sellers voluntarily negotiate water trades through water exchanges or bilaterally.

– Trades can be permanent or temporary, with limits placed on how much water can be traded out of a certain area.

– Governments may play a role in facilitating trades, ensuring third-party impacts are considered, and regulating overallocation.

– The goal is to move water to higher value uses through market forces while respecting environmental and social considerations.

Existing Water Trading Schemes

Some of the prominent and large-scale water trading schemes currently in operation include:

– Murray-Darling Basin, Australia: Spanning four states, this $2 billion per year market is one of the most developed in the world. Trades primarily move water from flood irrigation to higher-value uses like horticulture.

– Colorado River, US: A active market allows water to be reallocated between the seven US states and Mexico that share the river basin. Much of the trading is temporary and fluctuates with drought conditions.

– Chile: Chile pioneered tradable water rights in the early 1980s. An estimated 20-30% of irrigation water now changes hands through water markets each year.

– California: While water rights are still attached to land in California, local water banks allow fortrades. The state is trying to expand markets to better deal with recurring droughts.

– Brazil: The state of Rio Grande do Sul allows temporary and permanent water trades between irrigators on its large irrigation schemes.

Emerging Issues and Opportunities

While water trading shows promise as a tool, several issues still need addressing to fully capture its potential benefits:

Defining Rights: Clearly specifying the legal nature and flexibility of water rights is important to avoid conflicts and make trading more efficient. Rights may need to balance consumptive and environmental needs.

Infrastructure Changes: Moving water often requires distribution network changes which trades alone may not incentivize. Governments may need to coordinate and help finance infrastructure upgrades.

Addressing Third Party Impacts: Trades must consider how water quantity or quality changes may impact downstream users, return flows, and the environment. Mitigation policies are needed.

Creating Market Liquidity: Large established markets like the Murray-Darling illustrate water trading’s viability, but other areas require developing supporting institutions, information platforms, and familiarizing farmers with market participation.

Pricing Water Sustainably: Water prices should incentivize conservation and reflect the true scarcity value of water supplies. Prices may need to adjust upwards over time to encourage demand management.

With the right enabling conditions and governance structures in place, water markets offer much promise for sustainably reallocating scarce water supplies in a cost-effective manner. As climate pressures intensify water scarcity, water trading deserves more policymaker attention and support as an effective water management tool. With careful development, it can guide water to its most economically and socially productive destinations.

Water trading presents an innovative solution for balancing competing water demands during times of shortage. By putting a price on water and allowing trading between willing buyers and sellers, scarce water supplies can be reallocated to higher valued uses through market mechanisms. While various issues still need addressed, experience from operational water trading schemes demonstrates its potential. With appropriate regulatory frameworks and supporting infrastructure, water trading may become an increasingly important tool for sustainably managing water scarcity under climate change. Its further development deserves policy priority and long term investment.
