Sustainable Development Goal 15.png

Sustainable Development Goal 15 (SDG 15) is one of the 17 Sustainable Development Goals developed by the United Nations.


15.1 By 2020, ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligations under international agreements

15.2 By 2020, promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests and substantially increase afforestation and reforestation globally

15.3 By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world

15.4 By 2030, ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development

15.5 Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and, by 2020, protect and prevent the extinction of threatened species

15.6 Promote fair and equitable sharing of the benefits arising from the utilization of genetic resources and promote appropriate access to such resources, as internationally agreed

15.7 Take urgent action to end poaching and trafficking of protected species of flora and fauna and address both demand and supply of illegal wildlife products

15.8 By 2020, introduce measures to prevent the introduction and significantly reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species

15.9 By 2020, integrate ecosystem and biodiversity values into national and local planning, development processes, poverty reduction strategies and accounts

15.10 Mobilize and significantly increase financial resources from all sources to conserve and sustainably use biodiversity and ecosystems

15.11 Mobilize significant resources from all sources and at all levels to finance sustainable forest management and provide adequate incentives to developing countries to advance such management, including for conservation and reforestation

15.12 Enhance global support for efforts to combat poaching and trafficking of protected species, including by increasing the capacity of local communities to pursue sustainable livelihood opportunities


Relevance of linguistics:

  • global support for efforts to combat poaching and trafficking of protected species, including by increasing the capacity of local communities to pursue sustainable livelihood opportunities - create an international network working in different languages

Example below


In the French and Spanish Basque Country, Dylan Inglis and Unai Pascual's [1] research on language and human-nature relations suggests that there is a link between biological and linguistic diversity that ties with the local's connection with both the language and the mountain forests. The research looks at the role and influence of euskara, the Basque language, in the people's relationships with mountain forests in the Western Pyrenees of the Basque Country.

"We conclude that positive relational values linked to Euskara may be seen as key levers for local sustainability transitions. The fact that positive rapports with language can have a meaningful role in human–nature relations points to the need for further research into the consequential links between biological and linguistic diversity" (Inglis and Pascual, 2021: 1).


Summary: Achieve specific goals (Protect, restore! and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss within certain time limit). The subpoints gives specific examples on how to achieve those goals and set time limits to promote progress.
