As a result of climate change, there has been a shift in the global weather pattern. The hydrological regime in river basins across the world is subjected to unprecedented extreme weather conditions. In the Thames Basin, the narratives about resilience against sudden floods and extended droughts have focussed on sustaining London through large, expensive infrastructural projects. As such extremities become common over time across the basin, the relationship between the megacity and its ecological hinterlands is turning increasingly strained.

The increasing intensity of water-related disasters like droughts and floods across the basin are a sign of disruptions in the flows of the water cycle, and the disproportionate degree of responses to addressing them signifies the biases within the power structures that control the supply, distribution, and treatment of water. The thesis seeks to examine these imbalances of power within integrated river basin management through the lens of urban political ecology to address the inequalities in how citizens in different settlements across the basin are exposed to water risks in terms of compromised quantity and quality of water.

In addition to seasonal flooding risks, the entire basin is subjected to threats to water security as a result of population growth, changes in rainfall patterns, and high levels of pollution. This threat to water security is affecting the countryside’s ability to sustain its agricultural practices in the face of declining national food security. The project further seeks to adopt a site-sensitive approach to water risk management that acknowledges the water needs of the countryside. Moreover, with its position upstream of the basin, the actions towards water management taken here to slow the river and increase groundwater infiltration could help reduce the intensity of fluvial flooding downstream and work towards recharging fresh water supplies.

‘Down to Earth’ proposes regenerative soil as the foundation of an innovative bio-based region in South Holland, that connects society and economy on all scales while restoring ecological systems. Agricultural Practices that have heavily relied on tilling and the heavy use of chemical fertilizers has reduced the quality of the topsoil compromising both food security and the carbon sequestration capacity of the soil. Additionally, Industries along the port of Rotterdam that is heavily dependent on fossil fuel have polluted the land it is based on and emitted large amounts of carbon. The most powerful technology we have at hand to draw down this carbon load is healthy soil that can support plant life and micro-organisms naturally.

The strategy proposed in this report focuses on retaining the economic prosperity of South Holland while remediating the soil that supports it. Based on an understanding of the current land uses in South Holland and the level of disruption it causes to the natural systems within the soil, the region has been abstracted into pixels. Each spatial type would have a specific intervention that focuses on keeping the soil in it open and alive.

These interventions are further strengthened by creating links that support the exchange of biodegradable material and clean energy between stakeholders. This would serve as an additional economic incentive to support the pressing need to mitigate environmental damage. The guiding principles that make this transition possible include renewable energy generation, eco-sensitive development, nature-based solutions, valorization of biodegradable waste, and using policies to change consumer patterns and reformulate development trends. The proposal, along with the layers of soil data that support it is a case of why soil remediation through bio-based economic activity is vital to sustainable growth and a vision of what development within planetary boundaries would include.
