Better protection and restoration of coastal ecosystems

The ongoing urban resilience project aims to improve living standard and resilience to extreme natural events through supplying flood management, water, and sanitation infrastructure.

One of the consequences of global warming is the sea level rise. In urban settings along coastlines, rising seas threaten not only houses, but also several types of infrastructures such as industries,  roads, power plants, freshwater aquifers, etc. Rising sea-level also pushes destructive storm surges further inland, posing very high risks for coastal populations, as storm surges can push water kilometers inland, causing extreme flooding far from the coast.

Medellín, like many other cities, faces rising temperatures, worsened by the urban heat island effect—concrete and tarmac absorbing the sun’s power, radiating it out as heat and keeping the city warm long after the sun has gone down. It doesn’t have to be that way, as Colombia’s second-largest city, Medellín, is showing by embracing nature-based solutions.

With the Green Corridor project, which won the 2019 Ashden Award for Cooling by Nature Award, supported by the Kigali Cooling Efficiency Program and in partnership with Sustainable Energy for All, Medellín’s city authorities...

Seawalls are usually seen only as flood alleviation structures rather than as having other possible functions to benefit the wide environment. Where new walls are being installed there is opportunity to include more sympathetic “nature friendly” textured finishes to improve or maintain biodiversity. Where seawalls are already installed, retrofit enhancement measures provide significant opportunities. Small alterations were made to the mortar pointing between decorative stone cladding of a section of vertical concrete wall during construction of the Shaldon and Ringmore Tidal Defence Scheme...
