Is it possible for urban development to coexist with biodiversity conservation? Yes, definitely! 🌳🦆🦋🏙️🚲

As the source of food and a main contributor to our physical and mental well-being for the majority of the population in cities and urban "jungles", it is important that we take care of the biodiversity that can be found in these areas.

To achieve the global goal of living in harmony with nature, the Singapore Index on Cities’ Biodiversity or the City Biodiversity Index (CBI) was created to monitor and gauge the biodiversity conservation efforts of cities in comparison to pre-identified baselines.

On 11 July, through the joint efforts of the National Parks Board of Singapore (NParks), ICLEI-Local Governments for Sustainability’s Cities Biodiversity Centre (ICLEI CBC), the ASEAN Centre for Biodiversity and the World Wide Fund for Nature – Singapore (WWF), a global webinar called 𝘚𝘤𝘢𝘭𝘪𝘯𝘨 𝘵𝘩𝘦 𝘊𝘪𝘵𝘺 𝘉𝘪𝘰𝘥𝘪𝘷𝘦𝘳𝘴𝘪𝘵𝘺 𝘐𝘯𝘥𝘦𝘹 𝘧𝘰𝘳 𝘌𝘧𝘧𝘦𝘤𝘵𝘪𝘷𝘦 𝘐𝘮𝘱𝘭𝘦𝘮𝘦𝘯𝘵𝘢𝘵𝘪𝘰𝘯 𝘰𝘧 𝘵𝘩𝘦 𝘒𝘔 𝘎𝘉𝘍 was held featuring experts from different countries who employed the CBI in their respective cities.

For Asia-Pacific, Dr. Rajan Chedambath from India and Juan Pablo Yao from the Philippines discussed how the CBI was used in Kochi and Cebu. The resource persons also shared their best practices during the webinar.

One of the event's highlights was the premiere of a video produced by the ACB showcasing the rich and breathtaking biodiversity in the ASEAN while highlighting the success stories of different cities worldwide using the CBI.

Conserving biodiversity has a connection to ensuring that we are safe from zoonotic diseases. 🌿🐝

The 𝘚𝘢𝘧𝘦𝘵𝘺 𝘈𝘤𝘳𝘰𝘴𝘴 𝘈𝘴𝘪𝘢 𝘧𝘰𝘳 𝘵𝘩𝘦 𝘎𝘭𝘰𝘣𝘢𝘭 𝘌𝘯𝘷𝘪𝘳𝘰𝘯𝘮𝘦𝘯𝘵 (SAFE) project aims to minimise the risk of wildlife-related pandemic spillover to livestock and humans and mitigate its associated impacts while enhancing collaborative efforts with partners. It is supported by the European Union and implemented in cooperation with the Food and Agriculture Organization of the United Nations, and the United Nations Environment Programme.

From 10 to 11 July, Dr. Nur Hasanah Gauch, director of the ACB’s Biodiversity Science Division and Southida Souliyavong, Country Manager for Lao PDR, took part in the 𝘚𝘈𝘍𝘌 𝘈𝘥 𝘩𝘰𝘤 𝘌𝘹𝘱𝘦𝘳𝘵 𝘎𝘳𝘰𝘶𝘱 𝘔𝘦𝘦𝘵𝘪𝘯𝘨 held in Bangkok, Thailand, with representatives from the ASEAN Member States and regional One Health experts, among others.

During the event, Dr. Gauch discussed the initiatives of the ACB on wildlife and zoonotic disease, as well as the ACB’s role in implementing the ASEAN Comprehensive Recovery Framework and the ASEAN Strategy for Preventing Transmission of Zoonotic Diseases from Wildlife Trade.

Such a snake! 🐍

Snakes are often misunderstood. Many are terrified of them while others would instantly want to kill them.

However, snakes benefit ecosystems in several ways such as by regulating prey populations and serving as food sources for other animals.

They are also threatened by habitat loss, climate change, and diseases, which are also caused by human activities.

As we celebrate #WorldSnakeDay, let us learn more about these not-so-cuddly, but very important animals. Understanding them will help us appreciate their role and will inspire us to do more to keep their homes safe and their population intact.

Flight stopover and more! 🦆🦗

Wetlands are not just stopovers for migratory birds. They are abundant sources of food and also serve as breeding sites.

This coming November, the Wild Bird Club of the Philippines, in cooperation with the ACB and other like-minded organisations, will hold the 13th Asian Bird Fair in the #Philippines. The event, which was formally launched earlier this month, will highlight the importance of wetlands, not just for birds but also for the surrounding communities through exhibitions and interactive activities.
