Water Positive Think Tank
“Water Positive” is a concept that goes beyond a simple balance of water use. It refers to an entity’s strategic actions that lead to a net positive contribution to global water resources. There are several approaches to achieve this goal, and this proposal assembles more than 60 professionals from across the world, from varied disciplines, aiming to suggest yet another method: the purification of water through multi-barrier systems, a sustainable water source with a level of purity exceeding that which is currently found in nature. This balance, rooted in the calculation of the water footprint, takes into account various factors: from water footprint. water footprint trade, local water scarcity, social impact, economic, and environmental concerns. Initiatives under the “Water Positive” banner can encompass watershed restoration projects such as reforestation, groundwater recharge, wetland conservation, and river clean-ups. Additionally, companies can amplify their positive contribution by financing access to drinking water and sanitation for communities lacking such facilities. In areas grappling with water scarcity, the purification of seawater and wastewater emerges as an essential strategy to bolster water availability and quality.
Different associations may have varying perspectives in some details, but there is a consensus on certain themes such as net positive balances, water quality, watershed-level impacts, and a holistic understanding of both direct and indirect water usage. As the concept of being water positive develops, the introduction of standardized metrics and certification programs is expected to promote more sustainable water management practices.
The UN Global Compact CEO Water Mandate promotes Net Positive Water Impact (NPWI) to build resilience for businesses and communities against climate change impacts. NPWI is a business ambition to create positive impact on water availability, quality, and access in water-stressed regions where companies operate. It involves companies contributing more towards reducing water stress than their own water impacts in a region.
Key aspects of NPWI are it is quantifiable and aligned with scientific water targets across the 3 dimensions of water stress – availability, quality, access. It manifests through collective action in water-stressed basins where impact matters most. It is measured via short-term outputs and long-term outcomes.
In summary, NPWI is an ambitious framework promoted by the UN Global Compact CEO Water Mandate and adopted by leading companies to create net positive impact on water availability, quality and access in water-stressed regions through quantifiable goals and collective action.
Water positive definition
The concept of water positive can be defined as:
“Being Water Positive refers to a concept where an entity, such as a company, community, or individual, goes beyond simply conserving water and actively contributes to the sustainable management and restoration of water resources. This involves implementing practices and technologies that reduce water consumption, improve water quality, and enhance water availability. The goal of being water positive is to leave a positive impact on water ecosystems and ensure that more water is conserved and restored than is used or depleted.”.
As it can be observed from the definition, water positive aims to restore water resources, thus leaving a positive impact on the water ecosystems. The focus should be on the quality of purified water, not on the source. Desalination and water reuse are two processes that are currently used to achieve this goal and when they are implemented correctly and according to the international standards, they are certainly sustainable activities to mitigate water scarcity and climate change.
Both desalination and water reuse allow us to tap into previously unusable water sources, such as seawater and wastewater. The technologies have advanced remarkably in recent decades, becoming more energy efficient and cost effective. With proper planning and management, desalination and reuse can be part of a sustainable approach to ensuring water security in a water-stressed world. There are still environmental impacts to consider, but these can be mitigated through careful facility design, discharges management strategies, and integrating renewable energy. With continued innovation and commitment to sustainability, desalination and water reuse can be truly transformative in building resilience to drought and climate impacts on freshwater resources.
How to become Water Positive?
The corporations leading this initiative have focused on several avenues to become water positive, such as watershed restoration projects, including reforestation, groundwater recharge, non-revenue water reduction, wetland conservation, and rivers cleaning. Others have financed access to drinking water and sanitation for communities in need (SDG 6) or supported sustainable agriculture practices.
As can be seen from the definition, being water positive aims to restore water resources, thus leaving a positive impact on global water resources. Water purification offers a renewable and sustainable source of high-purity water, which will allow industries to plan their replenishment strategies effectively.
Two processes that will become great allies for these companies are desalination and water reuse, which will allow us to take advantage of previously unusable water sources, such as seawater and wastewater. These technologies have advanced significantly in recent decades, becoming more energy-efficient and cost-effective. With proper planning and management, desalination and reuse can be part of a sustainable approach to ensuring water security in a water-scarce world. While there are still environmental impacts to consider, these can be mitigated through careful facility design, discharge management strategies, and the integration of renewable energy. With continued innovation and commitment to sustainability, desalination and water reuse can be truly transformative in building resilience to drought and the impacts of climate change on freshwater resources.
Although companies today are focused on building resilience for their own operations and the communities and ecosystems in which they operate, the next step we must consider is one of the most significant environmental impacts to which we have not paid sufficient attention: the Water Footprint Trade. Just as we are currently concerned about having a positive impact in the basins where we operate, we must also take responsibility for the basins from which we import virtual water through the inputs produced in areas of high water stress.
By measuring the water footprint, depending on the standard used, companies can trace their water footprint and plan their strategy accordingly. The approach we are working on is reminiscent of the carbon credit market. However, instead of offsetting CO2 emissions, the system offsets the water footprint. It is vital to understand the distinctions between the two: while carbon offsetting deals with gases and is consistent regardless of where the gas is emitted, water offsetting influences myriad considerations. These include the water footprint, water footprint trade, local water scarcity, and the associated social, economic, and environmental implications.
While the model is still in full development, planned to be completed by the end of 2025, it could work as follows: A country that exports thousands of tons of water as virtual water in its products, including a significant amount of water from wells, a non-renewable resource, faces a challenge as this water does not return to the country. However, it is necessary to continue exporting to maintain a healthy economy. The initiative proposes that companies located in regions with high water availability, which have imported water-intensive products from such countries, offset their water footprint at the source. This is known as creating a positive impact. If they offset their water footprint in an area with excess resources, they would be limited to achieving water balance, without generating any significant social or economic impact.
Given the many advances in our society, much of our anthropogenic impact comes from the same technology that fueled our evolution. It is now imperative to harness this technology for the benefit of nature. As we continue to evolve, we must also commit to improving our planet.
Introduction
The Water Positive Think Tank (WPTT) is a group of more than a hundred professionals from different disciplines, continents, cultures, and traditions, voluntarily gathered to think, analyze, and share knowledge about the water cycle; its production, conservation, transformation, and depletion. The current scenario demands it, since if corrective actions are not initiated, close to two billion people will not have access to water by 2050. We must study, promote, and advocate for what is necessary to reverse this situation, and to do so, we will collaborate with any association that is open to this common purpose, leveraging all our acquired knowledge, and working together to achieve a future that leaves no one behind.
At the United Nations Water Conference in March 2023, organized in New York, the second after the Mar del Plata conference in 1977, the founders of the think tank understood that the call to action, so present in each presentation at that event, was an appeal to the direct and personal commitment of those who had the knowledge and experience: we had to assume this responsibility. Immediately, more than fifty professionals joined this group of thinkers, where participation, freedom of thought, and above all, a scientific and systemic approach prevail to seek synergies and jointly promote advances in the 2030 Agenda and the necessary Water Resilience for all.
90% of the world’s water footprint is generated by industry, with only the remaining 10% for direct human consumption, although 100% is a consequence of the anthropogenic effect. Water is essential for consumption, but it is also essential for the production of other equally necessary
goods. The analysis approach must necessarily be global, holistic, without pitting those uses against each other as rivals: we need water
for human consumption, as well as for producing our food, clothing, homes, or clean energy. We often think of water in SDG 6, but in reality, it is involved in each of the SDGs. The global economy depends on the production of goods, services, and energy, so if we were to lower the level of production due to a lack of water resources, the number of people affected would be much more than two billion, and not only due to a lack of water but also food.
Our initiative and model take into account a regenerative economy in water resources, so that the higher the level of production, the more available fresh water the model regenerates. The three dimensions proposed by the NPWI (Quality, Quantity, and Accessibility) are at the center of the system, and water purification, storage, and distribution in a sustainable way are key.
The concept of “Water Positive” encompasses all the strategic actions of an entity that lead to a net positive contribution to water resources where a negative impact on resources would have occurred, taking into account the traceability of the water footprint (because in some cases, the impact is generated far from the place where the company operates).
Our objective is to collect and organize each action that leads to a positive impact on water resources in a sustainable way, in the three dimensions mentioned (quality, quantity, and accessibility), and make them available in the Water Positive Framework to understand, analyze, and disseminate them in a simple and clear way, and above all, based on scientific evidence.
Target Audiences
- CEOs, Chief Sustainability Officers (CSOs), and other sustainability managers in the private sector
- Non-governmental organizations (NGOs) and other implementers of water-related projects
- Startups and innovative companies developing water-related solutions
- Public officials involved in the development of water-related public policies
Promoting a Global Alliance of Associations for Industrial Water Footprint Compensation
Initiating and strengthening a worldwide network of organizations focused on water resources, with the key objective of neutralizing the industrial water footprint, which accounts for approximately 90% of global water consumption. This alliance, conceived as an SDG 17 partnership, will commit to promoting and adopting Water Positive practices through the use of unconventional water resources, which are the only source capable of producing the volume of water needed to offset the industry’s footprint and tackle water scarcity in water-stressed basins. While savings and efficiency have made significant progress in recent years, It is clear that a much larger quantity of fresh water needs to be generated to meet existing and growing demands.
This network will facilitate effective collaboration, the exchange of knowledge, regulations, and advanced technologies, and the implementation of coordinated strategies to significantly reduce the industrial water footprint, marking a significant step in water resource management through what we like to call the second membrane revolution after its discovery.
From the WPTT, we look forward to collaborating with all corporations committed to this initiative, alongside non-governmental organizations (NGOs) related to water, energy, and food, as well as universities, so that by 2050, we find ourselves in a better situation than what we have been forecasting based on current water resource trends.
Our Purpose
Our team of over 100 dedicated leaders from around the world, representing more than 20 different disciplines, works together in a transdisciplinary, inclusive, and consensus-driven approach, placing science at the forefront of our decision-making process. Motivated by a shared vision of a better world, we collaborate to share our knowledge and strive to make a positive impact on global water resources. Our contribution, firmly grounded in science and technology, is inspired by the actions taken by the corporations spearheading this initiative and the clarion call from the CEO Water Mandate of the United Nations Global Compact and its Water Resilience Coalition for companies to embark on the Net Positive Water Impact (NPWI) journey.
Our mission is to propose complementary methods to those currently in use, emphasizing water purification through non-conventional water resources. By doing so, we aim to provide a renewable and sustainable water source that offers an unlimited, climate-independent alternative to all stakeholders. Although this work is not intended to serve as an exhaustive guide to corporate water replenishment decisions, we firmly believe that it will augment existing guidance documents and resources, empowering leaders in this field to expand the range of possibilities and accelerate the achievement of committed outcomes.
Like the corporations that have embarked on this journey, we acknowledge that our learning process is continuous and that there is still much to discover and share. As outlined in Sustainable Development Goal 17, “Partnerships for the goals,” we are committed to standing alongside those who require assistance in achieving a positive impact on water resources across three dimensions: availability (quantity), quality, and access.
We eagerly anticipate sharing updates as we refine our strategy and expand our project portfolio.
