Increase achievements of biodiversity targets

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...

Biodiversity conservation and wetland protection programme

Project introduction:

The Changyuanhe river is in Qixian, Jinzhong City, Shanxi Province, in North and Middle China and become the main axis of the project, both by its cultural and ecological important for the country. In the past, there were large areas of marsh wetlands along the river, which can regulate and enrich the ecological diversity with good water power. Today the contrast between the upstream natural area (which is still well preserved) and the downstream area (which is dry for four months of the year) is astonished. The project aims to afforest the 30km river...

Air quality in urban areas is a known issue for health and quality of life. Motorised vehicles produce a range of pollutants that can affect human health. These include very small particles emitted from exhaust (especially from diesel-fuelled vehicles), and from wear-and-tear on brakes and tyres. If inhaled these particles can cause a range of both short-term and more chronic health problems, including increased chances of death from respiratory and cardiovascular disease. This Particulate Matter (PM) is measured in microns (one micron is one millionth of a metre). Health concerns start...
