Ecological restoration is of crucial importance to mitigate the impact of human activity on the environment and preserve biodiversity and ecosystem services. Therefore, the concept of restoration is at the core of international and European Union (EU) environmental policy and governance. This article seeks to shed light on this concept in international and European case law. To this end, it reviews the definition, objectives and scope of restoration according to international scientific standards. It further distinguishes restoration from other related terms such as compensation, mitigation, conservation and rehabilitation. The article then analyses judgements rendered by the International Court of Justice, the Court of Justice of the EU and EU Member States' courts pertaining to restoration. It concludes that there are wide discrepancies in the use of the term restoration by the judiciary, in particular with regard to objectives, baselines and reference conditions. In light of these conclusions, the authors support the adoption of a legal definition of restoration.
| INTRODUCTIONNature and the ecosystem services that it provides to humans are deteriorating at an unprecedented rate due to human-induced changes in ecosystems' composition and functioning. In the last 50 years, the human population has doubled, the global economy has grown fourfold and global trade has grown tenfold, which has accelerated the global demand for energy, materials, food and land, and fostered massive biodiversity loss. 1 This ecological emergency is a direct result of human activities, and it puts at risk the achievement of all biodiversity targets for 2030, human wellbeing and all life on Earth. 1 S Díaz et al (eds), Summary for Policymakers of the Global Assessment Report on Biodiversity and Ecosystem Services of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Secretariat 2019) 12.
