Protecting nature in Sri Lanka’s capital for resilience and sustainability

The world is urbanizing at a very fast pace – but it seems like Sri Lanka is an exception.

In 2014, the island was listed as one of the least urbanized countries in the World Urbanization Prospects (WUP),  with less than 20 percent of the population in urban areas. By 2050, WUP projected that number would rise to only 30 percent.
 
Does this mean we still have to worry about the country’s urbanization? The short answer is yes.

This is, after all, an island nation with one of the highest population densities, complex and evolving social systems and intricate ecosystems.

Meanwhile, urbanization, even at relatively slower pace, is still changing migration patterns, altering the way urban populations consume resources, and impacting the affordability of land and other assets.

These, in turn, are increasing the demand for resources. Growing inequality can be seen as a result of the displacement of less affluent communities, while the loss of important ecosystems has negatively affected resilience and sustainability.

Mighty Mangroves of the Philippines: Valuing Wetland Benefits for Risk Reduction & Conservation

Michael Beck's picture
Mangroves are weeds; if you give them half a chance they grow in some of the most inhospitable environments; with their knees in seawater and their trunks in the air. They create forested barriers between the wrath of the seas and our coastal communities providing benefits in coastal defense and fisheries. Unfortunately there are too many examples where we have not given mangroves half a chance; hundreds of thousands of hectares have been lost to pollution, aquaculture and other developments. These represent real losses to the coastal communities – often some of the most vulnerable communities living in the highest risk areas.
 
A recent study estimates that without mangroves, flooding and damages to people, property and infrastructure in the Philippines would increase annually by approximately 25%.
