What is the World Day to Combat Desertification and Drought?
The World Day to Combat Desertification and Drought, also known simply as Desertification and Drought Day, takes place on Thursday 17 June 2027. The UN-led observance raises awareness of the threats posed by land degradation, desertification, and drought, and the urgent need for restoration. The 2026 theme was “Rangelands: Recognize. Respect.

The World Day to Combat Desertification and Drought is an annual UN observance led by the United Nations Convention to Combat Desertification (UNCCD). The day brings global attention to the impacts of desertification, land degradation, and drought, while celebrating progress made in land restoration. It encourages governments, communities, and businesses to invest in healthy soil, sustainable land use, and resilience to climate change.

Why the World Day to Combat Desertification and Drought Matters
Land degradation affects the lives of an estimated 3.2 billion people worldwide. Desertification turns once-productive land into barren ground, reducing food security, displacing communities, and amplifying climate change. Drought, increasingly intensified by climate change, compounds the problem, causing crop failures, water shortages, and economic loss. The day urges governments and the public to recognise these realities and invest in restoration.
How to Get Involved in the World Day to Combat Desertification and Drought
There are many ways individuals, schools, and organisations can take part:
- Learn about your local landscape – Find out where the soil, water, and biodiversity in your area come from, and what threats they face. Local conservation groups often run free walks and talks.
- Plant native species – Whether in a garden, a balcony pot, or a community plot, native plants support biodiversity, hold soil, and require less water.
- Reduce food waste – Around a third of food produced globally is wasted, and food production is a major driver of land degradation. Cutting waste reduces pressure on soils and water.
- Support sustainable agriculture – Buy from farmers and brands that use regenerative or organic practices, which build soil rather than deplete it.
- Conserve water – Fix leaks, install water-saving devices, and rethink lawn watering. Drought-resilient gardens use far less water without sacrificing beauty.
- Volunteer for tree planting or restoration – Many local environmental charities and the National Trust organise tree planting and habitat restoration days.
- Engage with policy – Write to your MP about commitments to UNCCD targets, sustainable land management, and overseas aid for land restoration.
History of the World Day to Combat Desertification and Drought
The day was established by the UN General Assembly in December 1994, six months after the adoption of the United Nations Convention to Combat Desertification (UNCCD) on 17 June 1994 in Paris. The Convention was the first legally binding international agreement to address desertification, recognising that drylands are particularly vulnerable to overuse and inappropriate land management.
The day was first observed on 17 June 1995 and has been marked annually ever since. In 2019, the UN streamlined the name to “Desertification and Drought Day” for accessibility, although many organisations still use the longer official title. Each year a different theme guides the campaign, covering topics from land tenure and women’s roles in land restoration to drought resilience and the link between healthy land and economic prosperity.
