Water Week: Protecting Our Most Precious Resource

Water is fundamental to life and essential to our daily wellbeing. While this may seem widely understood, it remains important to continually remind ourselves of the value of this finite resource. Although approximately 70% of the Earth’s surface is covered by water, only about 2.5% of it is freshwater available to sustain ecosystems and human needs.

Residents of Cape Town vividly remember the threat of “Day Zero” in 2018, when critically low dam levels meant that municipal taps could potentially be shut off. Through collective action, strict water-saving measures, awareness campaigns, and much-needed rainfall, the city successfully avoided this crisis. However, the experience served as a stark reminder that water security can never be taken for granted. Today, similar concerns are emerging elsewhere in the province. For example, the town of Knysna—approximately 489 kilometres from Cape Town—is currently facing its own potential water crisis. These situations also highlight the persistent inequalities that exist in access to safe and reliable water.

Climate change continues to intensify pressures on water resources. Increased frequency of droughts in some areas and flooding in others disrupts the availability and reliability of water supplies. As a result, protecting ecological infrastructure—such as catchments, wetlands, and river systems—has become more critical than ever. Healthy ecosystems play a vital role in storing, filtering, and regulating freshwater resources that communities depend on.

Access to safe drinking water is also closely linked to socio-economic conditions. In many communities, particularly those that are marginalised, water access remains limited. Promoting water conservation can be challenging in these contexts, where households may already struggle with minimal supply and rely on communal taps, rivers, or streams for daily water needs. In many cases, the responsibility of collecting water falls disproportionately on women and girls, creating a significant physical and time burden. This responsibility can limit opportunities for education, employment, and participation in other activities, while also exposing individuals to risks such as crime and abuse. Improving access to reliable water and sanitation services can therefore play an important role in reducing gender inequalities in a country already facing serious challenges related to gender-based violence.

CapeNature contributes to addressing these challenges by supporting United Nations Sustainable Development Goal 6, which aims to ensure the availability and sustainable management of water and sanitation for all. Through the conservation of ecological infrastructure—including strategic water source areas, catchments, rivers, and wetlands—CapeNature helps safeguard the natural systems that supply freshwater to communities across the Western Cape.

However, increasing urbanisation and population growth continue to place significant pressure on water supply systems. As cities expand, water infrastructure must meet the needs of growing populations while maintaining strict health and safety standards. At the same time, rising pollution levels pose an additional threat to freshwater ecosystems. Of the 138 freshwater ecosystem types in the Western Cape, 101 are currently considered threatened. More than 35% of river ecosystem types and over 40% of wetland ecosystem types are not yet formally protected. These figures highlight the urgent need for stronger conservation and management efforts.

Addressing water security challenges requires a collective and integrated approach. Complex societal issues cannot be solved in isolation, and every sector of society has a role to play. Education and awareness remain essential tools, but they must recognise the realities and inequalities experienced by different communities. Empowering communities to participate in water governance and reinforcing that access to clean water is a fundamental right—not a privilege—are critical steps toward sustainable water management.

At the same time, reducing water pollution, discouraging the improper disposal of harmful chemicals, and encouraging the adoption of water-efficient technologies can significantly contribute to protecting this precious resource. Regular maintenance and improvement of existing water infrastructure is equally important to ensure reliable supply and reduce losses.

Ultimately, protecting our wetlands, rivers, groundwater, and catchment areas is essential not only for our own wellbeing but for the health of the entire planet. By working together to safeguard these vital ecosystems, we can help ensure that clean, reliable water remains available for current and future generations.
