Water Stewardship

Water stewardship refers to the responsible planning and management of water resources, encompassing both the direct water use of an organization and its impact on shared water resources. It is a commitment to using water in a way that is socially equitable, environmentally sustainable, and economically beneficial. This goes beyond simply reducing water consumption within a facility; it involves understanding and addressing water-related risks and opportunities across the entire water catchment or watershed where an organization operates. The concept of water stewardship emerged from a growing recognition that water is a shared resource facing increasing pressure from population growth, industrialization, pollution, and climate change. Early efforts focused primarily on internal water efficiency and compliance with environmental regulations. However, as water scarcity and quality issues became more pronounced and localized, businesses realized that their water security was intrinsically linked to the health of the broader water system and the actions of other users. This led to a shift towards a more holistic, collaborative, and context-specific approach. The primary purpose of water stewardship is to ensure the long-term availability and quality of freshwater resources for all users, including ecosystems. For businesses, it serves several critical functions:

• Risk Mitigation: It helps identify and manage operational, regulatory, reputational, and financial risks associated with water scarcity, pollution, and extreme weather events.
• Operational Resilience: By optimizing water use and engaging in catchment-level solutions, businesses can secure their water supply and reduce vulnerability to disruptions.
• Social License to Operate: Demonstrating responsible water management builds trust with local communities, regulators, and investors, enhancing an organization's reputation and social acceptance.
• Environmental Sustainability: It contributes directly to the health of freshwater ecosystems, biodiversity, and climate change adaptation efforts.
• Supply Chain Stability: Addressing water risks within supply chains helps ensure the continuity of raw material sourcing and production.

Water stewardship is a critical component of broader sustainability initiatives, closely related to concepts like Resource Management, Environmental Compliance, and Corporate Social Responsibility. It provides a practical framework for businesses to understand their water footprint, assess their water risks, and implement strategies that benefit both their operations and the shared environment. Unlike simple water conservation, which focuses on reducing usage, stewardship emphasizes understanding the local water context, engaging with stakeholders, and contributing to collective solutions for sustainable water management. It recognizes that water challenges are often systemic and require collaborative action beyond the fence-line of individual facilities.

Implementing water stewardship typically follows a structured, cyclical process that moves from assessment and commitment to action, monitoring, and continuous improvement. This approach is often guided by international standards, such as the Alliance for Water Stewardship (AWS) Standard, which provides a globally applicable framework. The core workflow involves five key steps:

1. Gather & Understand: This initial phase involves a comprehensive assessment of the organization's water use, impacts, and dependencies. It includes mapping the operational water footprint (direct and indirect), understanding the local water catchment context (e.g., water availability, quality, governance, stakeholder interests), and identifying water-related risks and opportunities. Tools like water balance assessments, stakeholder mapping, and risk matrices are commonly used.
2. Commit & Plan: Based on the understanding gained, the organization develops a water stewardship strategy. This involves setting clear, measurable, achievable, relevant, and time-bound (SMART) goals and targets for water performance. These targets often cover aspects like water efficiency, wastewater quality, and engagement in collective action. A formal commitment from leadership is crucial, often articulated in a water policy.
3. Implement & Act: This is where the strategy is put into practice. Actions typically fall into two categories:
   • On-site Actions: Implementing water-saving technologies, optimizing processes, improving wastewater treatment, and promoting water-efficient practices within the facility.
   • Collective Actions: Engaging with other water users, local communities, government bodies, and NGOs within the catchment to address shared water challenges. This could involve funding watershed restoration projects, participating in water user associations, or advocating for improved water governance.
4. Evaluate & Disclose: Organizations continuously monitor their water performance against established targets. This involves collecting data on water withdrawals, discharge quality, and progress on collective actions. Regular reporting, both internally and externally (e.g., through sustainability reports or CDP Water Disclosure), ensures transparency and accountability.
5. Review & Improve: The entire water stewardship program is periodically reviewed to assess its effectiveness, identify areas for improvement, and adapt to changing conditions. This iterative process ensures that the organization's water stewardship efforts remain relevant and impactful, driving continuous improvement in water management practices. Third-party verification, such as certification to the AWS Standard, can provide independent assurance of adherence to best practices.

Water stewardship offers significant advantages for businesses but also presents distinct challenges in its implementation. Understanding these aspects is crucial for developing an effective strategy.
