Nature-Based Solutions in Coastal Governance, A Legal Analysis of Beach Concession Contracts in Mar del Plata, Argentina
This legal analysis of beach concession contracts in Mar del Plata, Argentina, reveals that while environmental principles are increasingly integrated into tender specifications, the absence of explicit Nature-Based Solutions and dynamic ecosystem considerations necessitates a shift toward integrated coastal management to ensure climate resilience and sustainable water use.

The coast is a place where the land meets the sea, a dynamic boundary that has always shifted with the tides and the storms. In recent decades, however, this boundary has become a zone of intense pressure. As global temperatures rise, the oceans are swelling, pushing higher up the shore and threatening to swallow the beaches that communities and economies rely on. At the same time, the water beneath our feet is under siege. In many coastal towns, the fresh groundwater that people drink is slowly being pushed out by the encroaching saltwater from the ocean, a process that accelerates when too much water is pumped from the ground. To solve these problems, scientists and planners are increasingly looking toward Nature-Based Solutions. These are not high-tech gadgets or concrete walls, but rather approaches that work with natural systems—like restoring dunes or managing water more wisely—to protect communities and ecosystems. The question remains, however, whether the laws and contracts that govern these busy coastal areas are actually ready to use these natural tools.
In the bustling resort city of Mar del Plata, Argentina, two researchers set out to answer this question by looking directly at the paperwork that keeps the beaches running. Mar del Plata is a major destination, drawing millions of visitors every summer to its sandy shores. To manage the beachfront, the local government divides the coastline into specific zones called Fiscal Tourist Units. These are areas where private companies are granted long-term contracts, or concessions, to run facilities like restaurants, changing rooms, and pools. The researchers, Cecilia Lucía Mantecón and Clara María Minaverry, examined the legal documents for thirty-six of these active contracts. They wanted to see if the rules written for these businesses included modern strategies for dealing with climate change, specifically the use of Nature-Based Solutions to manage water and protect the shoreline. They also looked at the broader laws that govern the entire country and the province to understand the legal landscape.
The study found that the legal framework has made significant progress in recognizing the environment. Most of the contracts now require businesses to conduct an environmental impact assessment, a process that forces them to think about how their operations might harm the local ecosystem. The rules also demand that water be used efficiently, with specific requirements for things like automatic shut-off valves on showers and systems to treat wastewater before it is released. These contracts even reference a voluntary quality standard that encourages sustainable practices. However, when the researchers looked for the specific, innovative approaches known as Nature-Based Solutions, they found them largely missing. The contracts do not explicitly ask for the restoration of native vegetation, the monitoring of the underground water tables, or the use of natural barriers to stop erosion. Instead, the documents tend to use a one-size-fits-all approach, applying the same standard rules to every beach regardless of its unique shape, soil type, or specific vulnerability to the rising sea.
A critical issue identified is the mismatch between the length of these contracts and the reality of a changing coast. The agreements often last for twenty or thirty years, a timeframe that assumes the beach will stay in the same place. Yet, the shoreline is constantly moving, retreating or advancing with the seasons and storms. By locking in long-term plans without building in a way to adapt to these changes, the current system risks becoming obsolete before the contract even ends. The researchers also noted that the laws governing these areas are scattered and incomplete, lacking a single, comprehensive plan for the entire coast. While the rules successfully address immediate concerns like waste and water usage, they have not yet evolved to fully embrace the idea that working with nature is the most effective way to ensure the beaches survive the challenges of the future. The study concludes that for Mar del Plata and similar coastal cities to remain safe and sustainable, the legal system must shift toward a more flexible, integrated approach that actively incorporates natural solutions and adapts to the shifting sands.
