Unlocking the Potential of Nature-Based Solutions for Equitable Water Access
Access to safe, reliable, and affordable water is a fundamental human right, yet millions of people around the world continue to face barriers to meeting their basic water needs. This crisis is particularly acute in marginalized communities, where water scarcity and poor infrastructure disproportionately burden women and girls. However, innovative nature-based solutions like rainwater harvesting are emerging as powerful tools to enhance household water security and promote gender equity.
The Gendered Burden of Water Insecurity
Water insecurity is a global challenge, but its impacts are far from evenly distributed. In many parts of the world, the responsibility of water collection, storage, and management falls primarily on women and girls. This unpaid care work can consume hours of their time each day, limiting their opportunities for education, economic participation, and personal development.
One striking example comes from Mexico City, where over 50% of the population faces water scarcity. In some of the city’s marginalized communities, women can spend up to an entire working week on water-related activities, such as hauling water from distant sources or managing household supplies. This inequitable burden not only exacerbates gender gaps, but also undermines broader efforts to achieve sustainable development.
Rainwater Harvesting: A Transformative Solution
Amidst these daunting challenges, innovative approaches rooted in natural systems offer hope. Rainwater harvesting, the collection and storage of rainwater for domestic, agricultural, or even commercial use, has emerged as a promising nature-based solution to enhance water security and promote gender equity.
The Global Alliance to Improve Water Security through Promoting Rainwater Harvesting and Management, a partnership of national rainwater harvesting associations, is at the forefront of this movement. By strengthening initiatives, facilitating training and knowledge-sharing, and advocating for supportive policies, the Alliance is working to scale up rainwater harvesting as a sustainable, climate-resilient water management strategy.
Empowering Households through Rainwater Harvesting
One success story from the Alliance’s work can be found in Mexico City, where the government’s “Rain Harvest” program is making significant strides in improving water access and reducing the burden on women. The program, which prioritizes households headed by women, single mothers, and other marginalized groups, has already installed over 13,000 rainwater harvesting systems in the city’s most water-stressed areas.
These systems capture and store rainwater from rooftops, providing families with a reliable, supplementary water source for up to eight months of the year. By reducing the need to haul water from distant sources, the program has freed up significant time for women, enabling them to pursue educational and economic opportunities.
Moreover, the program’s training component promotes the equitable distribution of water-related tasks within the household, empowering both men and women to participate in the system’s operation and maintenance. This approach not only enhances the sustainability of the solutions, but also fosters more gender-inclusive water management practices.
Co-Benefits of Rainwater Harvesting
The benefits of rainwater harvesting extend beyond just water security and gender equity. By reducing the strain on overburdened municipal water systems and groundwater resources, these nature-based solutions also contribute to broader environmental and climate resilience objectives.
For example, in Philadelphia, the city’s ambitious plan to mitigate combined sewer overflows through green infrastructure has led to the installation of over 2,800 rainwater harvesting systems, preventing millions of cubic meters of polluted runoff from entering local waterways. This not only improves water quality, but also helps to recharge groundwater supplies and support urban ecosystems.
Similarly, in Semarang, Indonesia, the city’s adoption of rainwater harvesting as part of its climate change adaptation strategy has yielded multiple benefits. By reducing the burden on the city’s limited water resources, the systems have increased water security for households, while also contributing to flood mitigation and urban cooling through the provision of additional green spaces.
Scaling Up Rainwater Harvesting for Sustainable Development
The success stories from Mexico City, Philadelphia, and Semarang demonstrate the transformative potential of rainwater harvesting to address the interconnected challenges of water insecurity, gender inequality, and environmental sustainability. As the Global Alliance and its national partners continue to advocate for and support the expansion of these initiatives, they are paving the way for more equitable, resilient, and sustainable communities around the world.
However, realizing this potential will require a concerted, multi-stakeholder effort. Governments, civil society organizations, private sector partners, and community members must work together to ensure that rainwater harvesting projects are designed and implemented with an equity-focused, participatory approach. This means actively engaging women and other marginalized groups in the planning, decision-making, and implementation processes, and ensuring that the distribution of benefits is inclusive and just.
By championing rainwater harvesting as a nature-based solution, the Global Alliance and its partners are not only addressing immediate water needs, but also laying the groundwork for a more sustainable and equitable future. As the world strives to achieve the Sustainable Development Goals, these initiatives offer a promising pathway to unlock the transformative power of water security for all.
