2017 Theme: Forests and energy

This global celebration of forests provides a platform to raise awareness of the importance of all types of woodlands and trees, and celebrate the ways in which they sustain and protect us. This year we highlight the importance of wood energy in improving people's lives, powering sustainable development and mitigating climate change.

Arbor Day

Arbor Day is a holiday in which individuals and groups are encouraged to plant and care for trees. Today, many countries observe such a holiday. Though usually observed in the spring, the date varies, depending on climate and suitable planting season.

The People's Republic of China celebrates Arbor Day on March 12.

2017 theme “Listen to the Young Voices”

World Wildlife Day will be celebrated in 2017 under the theme “Listen to the Young Voices.” Given that almost one quarter of the world’s population is aged between 10 and 24, vigorous efforts need to be made to encourage young people, as the future leaders and decision makers of the world, to act at both local and global levels to protect endangered wildlife. 

Wetlands for Disaster Risk Reduction

Wetlands cover a range of ecosystem types such as lakes, rivers, floodplains and coastal mangroves and they provide a range of important services for both people and the environment. They act as natural safeguards against disasters, which makes them important for protecting communities most at risk and vulnerable to the devastating effects of floods, droughts and storm surges.

Theme: Climate is changing. Food and agriculture must too

One of the biggest issues related to climate change is food security. The world’s poorest - many of whom are farmers, fishers and pastoralists - are being hit hardest by higher temperatures and an increasing frequency in weather-related disasters.

At the same time, the global population is growing steadily and is expected to reach 9.6 billion by 2050. To meet such a heavy demand, agriculture and food systems will need to adapt to the adverse effects of climate change and become more resilient, productive and sustainable. This is the only way that we can ensure the wellbeing of ecosystems and rural populations and reduce emissions.
