Ethical and Social Dimensions of Water Rights Trading

The rise of water markets has been hailed by many as a triumph of economic efficiency. By treating water as a tradable commodity, it is argued, we can ensure that this precious resource is put to its most productive use. But the commodification of water is not without its critics. For many, the idea of putting a price on water is morally repugnant, and the prospect of a world where the rich can buy and sell water while the poor go thirsty is a dystopian one. As professional traders and investors, it is incumbent upon us to engage with these ethical and social dimensions of water rights trading.

The Human Right to Water

At the heart of the ethical debate over water markets is the concept of the human right to water. In 2010, the United Nations General Assembly recognized the human right to water and sanitation, declaring that clean drinking water and sanitation are essential to the realization of all human rights. This right is not just about a bare minimum of water for survival; it is about having access to a sufficient, safe, acceptable, physically accessible, and affordable supply of water for personal and domestic uses.

The question is whether water markets are compatible with the human right to water. Proponents of water markets argue that they can be. By creating a more efficient allocation of water, they can free up supplies for those who need it most. And by providing a clear price signal, they can encourage conservation and the development of new water sources. Critics, however, argue that water markets are inherently inequitable. They contend that by treating water as a commodity, we are undermining its status as a fundamental human right and that we are creating a system where the poor will be priced out of the market.

The Social Impacts of Water Markets

In addition to the ethical debate over the human right to water, there are also a number of social concerns about the impact of water markets. These include:

• The Impact on Small Farmers: In many parts of the world, small farmers are being squeezed out of the water market by larger and more effective players. This can lead to the consolidation of land ownership and to the decline of rural communities.
• The Impact on Indigenous Communities: Indigenous communities often have a deep cultural and spiritual connection to water, and they may be disproportionately affected by the development of water markets.
• The Impact on the Environment: While water markets can be a tool for environmental protection, they can also have negative environmental impacts. For example, the trading of water can lead to the over-extraction of groundwater and to the degradation of aquatic ecosystems.

A Framework for Ethical Water Investing

For investors who are concerned about the ethical and social dimensions of water rights trading, there are a number of steps that can be taken to ensure that their investments are aligned with their values. These include:

• Due Diligence: Before investing in a water right, it is important to conduct a thorough due diligence process to assess the potential social and environmental impacts of the investment.
• Stakeholder Engagement: It is important to engage with all of the stakeholders who may be affected by a water investment, including local communities, indigenous groups, and environmental organizations.
• Transparency: It is important to be transparent about the nature of a water investment and about its potential impacts.
• Benefit Sharing: It is important to ensure that the benefits of a water investment are shared equitably with all of the stakeholders.

A Formula for Calculating a Social Impact Premium

The social impact of a water investment can be incorporated into the valuation of a water right by adding a social impact premium to the discount rate. This premium would reflect the additional return that an investor would demand to compensate them for the risk of a negative social impact.

VWR = PV(∑(E(P_a) * A_t)) / (1 + r + sip)^t

VWR = PV(∑(E(P_a) * A_t)) / (1 + r + sip)^t

Where:

• VWR is the value of the water right
• PV is the present value operator
• E(P_a) is the expected price of a water allocation
• A_t is the expected water allocation in period t
• r is the risk-free discount rate
• sip is the social impact premium
• t is the time period
