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.

Mangrove restoration in Costa Rica

A pilot mangrove restoration project in Costa Rica demonstrating how mangrove planting can benefit habitat and species conservation, whilst boosting the local economy. About 40% of Costa Rica’s mangroves were deforested following the collapse of the country’s banana boom in the 1980s. A vigorous fern species has taken over much of the deforested area, preventing the mangroves from re-establishing. A pilot restoration project of 30 ha of mangrove in a protected wetland was implemented, involving clearance of the ubiquitous fern, planting of saplings, and continued fern removal for a few...

Alcaldía de Medellín - Green Corridors Initiative

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...
