At present, the invasion of alien species as a global issue has aroused widespread concern from countries and international organizations around the world. International organizations such as the International Union for the Conservation of Natural Resources and the International Maritime Organization (IMO) have developed how to introduce alien species and how to prevent, eliminate and control them. Technical documents such as guidelines for the invasion of alien species.
After the signing of the Convention on Biological Diversity by the United Nations Conference on Environment and Development in Rio de Janeiro in 1992, the threat of invasive alien species began to attract widespread attention on a global scale, and countries began to take planned actions. In July 1996, the United Nations and the Norwegian Ministry of the Environment jointly held an international conference on alien species attended by representatives of 80 countries and regions in Trachum, Norway. According to Article 8 of the 《Convention on Biological Diversity》, “in situ conservation” requires member states to introduce, control or eradicate the prevention of alien species that threaten ecosystems, habitats or species. The Principles apply to all areas of invasion and control of alien species, and the responsibility for the environmental and ecosystem damage caused by the intentional or unintentional introduction of alien species by the State or the government due to import and export trade is determined to be the benefit of import or trade.
At the sixth meeting of the Conference of the Parties to the Convention on Biological Diversity, held in The Hague, the Netherlands, in April 2002, the《 Guidelines for the prevention and mitigation of alien species》 that threaten ecosystems, habitats or species were adopted. The purpose of this guiding principle is to assist governments to take measures to resist the invasion of alien species, and to prevent and classify the invasion of alien species, the role of the state, surveillance, border control and quarantine, information exchange and cooperation, intentional introduction and unintentional introduction. 15 measures have been established to mitigate the impact and its eradication, and containment.
The invasion of marine aliens has been clearly stated in the 1982 United Nations Convention on the Oceans, and States must take all necessary measures to prevent, reduce and control the introduction of new aliens in a particular part of the marine environment, either intentionally or accidentally. Species cause major and harmful changes in the marine environment.
To prevent the invasion of alien species, more than 40 international conventions, agreements and guidelines have been adopted, and many agreements are under development. Although many conventions still lack binding force to a certain extent, and there are still some gaps and contradictions in the formulation of quarantine standards, these documents still play an increasingly important role within a certain scope, and the International Maritime Organization, World Health The organization and the Food and Agriculture Organization of the United Nations are also working more actively to strengthen international cooperation to combat the invasion of alien species.
