This year’s observance of World Wildlife Day—3 March 2022—focuses on the recovery of key species and the restoration of the planet’s ecosystems. This important theme provides us with the opportunity to reflect on restoration actions and impact so far, and how we can and must support people and nature in the future.
From forests to farmlands, mountains to oceans, our ecosystems, both modified and natural, provide multiple environmental, economic and social benefits for people and for nature. Our forests support an estimated . Our freshwater bodies are home to . Mountain ecosystems host , while our oceans provide 99 per cent of the world’s living space. These diverse ecosystems and their species provide us with a range of essential ecosystem services—from biodiversity and climate change adaptation and mitigation, to support for our economies, health and security.
However, these ecosystems and their ability to deliver these ecosystem services are being damaged, degraded and destroyed, which directly impacts people and nature. Between 2015 and 2020, we lost approximately 10 million hectares of forests per year,1?and globally more than two thirds of our ocean ecosystems are now damaged, degraded or modified.2?On a finer scale, the International Union for Conservation of Nature (IUCN) lists over 8,400 species as critically endangered and nearly 30,000 species as endangered or vulnerable.
This loss of ecosystems and species leads to the loss of benefits for people and nature. From an economic perspective, it is estimated that . 3.4?Furthermore, an estimated 1.4 billion livelihoods, ranging from food and drinks to energy and water, are directly reliant on access to fresh water.5
We need healthy and productive ecosystems to benefit from the multiple environmental, economic and social benefits they provide. Ecosystem restoration offers the opportunity to effectively halt and reverse degradation, improve ecosystem services and recover biodiversity. It is estimated that 60 per cent of expected species extinctions could be avoided through the effective restoration of 15 per cent of converted lands.6 Furthermore, the protection of existing intact ecosystems and the restoration of degraded ecosystems has the potential to contribute to .
Around the world there are a growing number of examples of the environmental, economic and social benefits of restoring ecosystems and species. In Mobile Bay, Alabama, United States the restoration of oyster reefs led to a 53–91 per cent reduction in wave height and energy at the shoreline, while the local economy has benefited from improved seafood and greater fish stocks.7?And, looking forward, the aims to combine restoration of 100 million hectares of degraded land with the promotion of peace and security across the Sahel.
This year will feature various crucial political moments to compel and catalyse action for the recovery of our key species and the restoration of our ecosystems, including meetings on the , the United Nations Convention on the Law of the Sea and , among others. Discussions, commitments and implementation throughout the year will contribute towards the recovery of species and ecosystems, as well as the achievement of multiple international goals and targets. Such efforts align directly with the ambition and vision of the , set to run until 2030. Stemming from strong political will and backed by the private sector, non-governmental organizations, scientists and practitioners, this campaign aims to build a new global momentum around the core ambition of ecosystem restoration at regional, national and global scales.?
This is also a key year for several other pivotal International Decade campaigns aimed at supporting the recovery of species and ecosystems. The for example, calls upon actors to address the degradation of our ocean and coastal ecosystems and improve science for decision-making. The International Decade for Action on Water for Sustainable Development ?drives us forward on the conservation, management and restoration of our freshwater ecosystems and its unique freshwater flora and fauna. And, overarchingly, the Decade of Action for the Sustainable Development Goals (SDGs) compels us to deliver on the 2030 Agenda for Sustainable Development and the full breadth of SDGs.
All of these efforts demonstrate how the international community is working to ensure positive outcomes for people and nature at the same time, and everyone has a role to play. From local efforts to plant trees and restore intricate waterways, to immense multinational restoration efforts that involve huge swathes of our land and seascapes, there is an opportunity for us all to act now to support, engage and implement impact.
United Nations Environment Programme World Conservation Monitoring Centre
To enable global transformation to a sustainable future, the United Nations Environment Programme World Conservation Monitoring Centre (UNEP-WCMC) provides strategic leadership, technical expertise and evidence-based support to our partners on effective ecosystem restoration and species recovery. We aim to support the global community through legal, policy and planning frameworks that can scale-up efficient action to achieve restoration ambitions at local to global scales; support and deliver an accessible knowledge base allowing planners and practitioners to prioritize effective restoration efforts that deliver measurable, long-term environmental, social and economic benefits; and support monitoring to track and incentivize effective global restoration efforts and enhance adaptive management.
