World Environment Day 2021
Ecosystem restoration means assisting in the recovery of ecosystems that have been degraded or destroyed, as well as conserving the ecosystems that are still intact. Healthier ecosystems, with richer biodiversity, yield greater benefits such as more fertile soils, bigger yields of timber and fish, and larger stores of greenhouse gases.
Restoration can happen in many ways – for example through actively planting or by removing pressures so that nature can recover on its own. It is not always possible – or desirable – to return an ecosystem to its original state. We still need farmland and infrastructure on land that was once forest, for instance, and ecosystems, like societies, need to adapt to a changing climate.
Between now and 2030, the restoration of 350 million hectares of degraded terrestrial and aquatic ecosystems could generate US$9 trillion in ecosystem services. Restoration could also remove 13 to 26 gigatons of greenhouse gases from the atmosphere. The economic benefits of such interventions exceed nine times the cost of investment, whereas inaction is at least three times more costly than ecosystem restoration.
All kinds of ecosystems can be restored, including forests, farmlands, cities, wetlands and oceans. Restoration initiatives can be launched by almost anyone, from governments and development agencies to businesses, communities and individuals. That is because the causes of degradation are many and varied, and can have an impact at different scales.
Every World Environment Day is hosted by a different country, in which official celebrations take place, and this year’s host is Pakistan.
The Government of Pakistan plans to expand and restore the country’s forests through a ‘10 Billion Tree Tsunami‘ spread over five years. The campaign includes restoring mangroves and forests, as well as planting trees in urban settings, including schools, colleges, public parks and green belts.
Through the 10 Billion Tree Tsunami, Pakistan is contributing to the Bonn Challenge, a global effort linked to the UN Decade on Ecosystem Restoration. Under the challenge, countries are pledging to bring 350 million hectares of the world’s deforested and degraded land into restoration by 2030.
