Visit the official website for the observance by the Convention to Combat Desertification. They have prepared not only a special online event, but also a short film series and campaign materials where you can find the logo in several UN official languages. They also offer more information about the theme and the background that explains the roots of the link between comsumption and land degradation.
The 2030 Agenda for Sustainable Development declares that “we are determined to protect the planet from degradation, including through sustainable consumption and production, sustainably managing its natural resources and taking urgent action on climate change, so that it can support the needs of the present and future generations”. Specifically, Goal 15 states our resolve to halt and reverse land degradation.
International days are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
