For years, climate change was discussed mainly as an environmental issue. That definition is no longer sufficient. Today, it is also a financial issue, an infrastructure issue and, increasingly, a question of economic stability. Floods destroy property and infrastructure, droughts affect agriculture and water security, wildfires erase billions of dollars in assets, and extreme heat reduces productivity while increasing energy demand and placing additional pressure on cities and public services. Eventually, all of these impacts reach the economy, affecting governments, insurers, banks, businesses and households.

 

The figures are difficult to ignore. International disaster data show that direct economic losses from climate-related disasters increased by around 151 per cent, rising from approximately US$895 billion during 1978–1997 to US$2.245 trillion during 1998–2017. More recent years have continued to demonstrate the scale of the problem, with global losses from natural disasters reaching hundreds of billions of dollars annually. Climate-related disasters are therefore no longer isolated environmental events; they are major economic events.

 

This is why climate change is no longer being discussed only by scientists and environmental ministries. It has entered central banks and financial institutions. In 2017, eight central banks and financial supervisors came together in Paris to establish the Network for Greening the Financial System, with the aim of better understanding how climate and environmental risks could affect financial stability. By August 2026, the network had grown to 152 members across more than 95 countries. That expansion sends a clear message: The financial world increasingly recognizes that climate risk can become financial risk.

 

A property repeatedly exposed to flooding may lose value. Insurance may become more expensive or, in some cases, unavailable. Banks holding mortgages on vulnerable assets may become exposed. Drought can affect corporate profitability, agricultural production and loan repayment. Major climate disasters can place enormous pressure on public budgets and national infrastructure. The condition of the environment and the stability of the financial system are therefore becoming increasingly connected.

 

This is also where landscape architecture needs to enter the conversation in a much stronger way. Too often, landscape architecture is still treated as beautification: Trees are added after buildings are designed, parks are considered after roads and infrastructure are completed and landscape becomes the final layer of development. Climate change is making that approach increasingly outdated.

 

A wetland that stores floodwater is infrastructure. A park designed to absorb stormwater is infrastructure. An urban forest that reduces extreme heat is infrastructure. A restored river corridor protecting neighbourhoods from flooding is infrastructure. A coastal landscape that reduces the impact of storms is infrastructure. These are not simply attractive green spaces; they are working systems that reduce risk, protect assets and strengthen the resilience of cities.

 

That is the real value of green infrastructure. A well-designed landscape can perform several functions at the same time. It can manage water, reduce heat, restore biodiversity, improve public health, support mobility, enhance quality of life and reduce the financial consequences of climate-related disasters. In many cases, it can complement conventional infrastructure and reduce the pressure placed on expensive engineered systems.

 

At the same time, substantial amounts of capital are moving towards the climate transition. The European Green Deal and related programs aim to mobilize investment on a historic scale, with the European Commission committing to mobilize at least 1 trillion euros in sustainable investment. Multilateral development banks provided a record US$137 billion in climate finance in 2024 alone, while also mobilising significant additional private capital. Green bonds and other sustainable-finance instruments have grown into markets measured in trillions of dollars.

 

Yet, the need remains far greater than the available finance. Developing countries alone are expected to require hundreds of billions of dollars every year for climate adaptation in the coming decades. This creates a major global challenge, but also an enormous professional opportunity. The question is no longer simply whether climate finance exists. The question is whether cities, governments and professionals can develop enough credible, measurable and financially viable projects capable of attracting that capital.

 

This is where landscape architects must begin to think differently. It is no longer enough to say that a project is green, sustainable or environmentally friendly. Increasingly, we must demonstrate what it actually achieves. How much floodwater can it retain? How many homes can it protect? How much can it reduce urban temperatures? How much biodiversity can it restore? How much economic damage can it prevent? What is its lifecycle cost compared with conventional infrastructure? These questions are becoming just as important as the traditional questions of design.

 

Landscape architects therefore need to learn the language of finance as well as design. They do not need to become bankers, but they do need to understand how projects are funded, how climate risk is valued, how economic benefits can be measured and how resilient landscapes can become financially viable projects. The profession needs to move beyond producing attractive masterplans and begin helping governments and cities create bankable climate-resilience projects.

 

Instead of simply saying, “We want to build a park,” a city should be able to say, “We want to create a landscape system that reduces flood risk, lowers temperatures, increases biodiversity, improves public health and protects surrounding assets.” The physical project may still be a park, but economically and institutionally it becomes something much larger. It becomes infrastructure.

 

This shift also changes the role of the landscape architect. The landscape architect of the future will need to work much more closely with engineers, economists, hydrologists, climate scientists, insurers, development banks and financial institutions. Climate change is forcing professions that once worked separately to sit at the same table, because resilience cannot be designed by one discipline alone.

 

There is also a simpler economic argument behind all of this: Do we invest before a disaster happens, or do we pay after it happens? Societies can invest in wetlands, watersheds, urban forests, resilient parks and climate-adapted public spaces before disaster occurs, or they can spend far greater amounts rebuilding roads, homes, businesses and infrastructure afterwards. One approach builds resilience. The other repairs damage.

 

For landscape architecture, this represents one of the greatest opportunities the profession has faced in decades. The landscape of the future will not be judged only by how beautiful it is, but by how well it performs: How much water it manages, how much heat it reduces, how many people it protects, how much biodiversity it supports, how much damage it prevents and how much long-term value it creates.

 

Climate change is already changing how governments, banks and financial institutions understand risk. That, in turn, is changing where money is being invested. Landscape architects need to recognize that shift and position themselves at the center of it.

 

Green infrastructure is no longer simply an environmental ambition. It is becoming an economic necessity — and one of the defining forms of infrastructure for the cities of tomorrow.
