Ecology: ‘The Great Green Wall’ Of Africa (Video)

Development banks and states pledged a total of $14.32 billion over the next four years to build a “Great Green Wall” to help contain desertification in Africa’s northern Sahel region. But what exactly is it and how much progress has been made?

The Great Green Wall or Great Green Wall of the Sahara and the Sahel is Africa’s flagship initiative to combat the increasing desertification. Led by the African Union, the initiative aims to transform the lives of millions of people by creating a mosaic of green and productive landscapes across North Africa. 

Ecology: Benfits Of 50% Of Serengeti Grasslands Burning Each Year (Video)

After receiving twelve hours of solar energy every day, the Serengeti grasslands become a tinderbox, just waiting to be lit.

The vast majority of the African fires currently burning seem to be in grasslands, in exactly the places we expect to see fires at this time of year. These fires are usually lit by cattle farmers as part of their traditional management of the savannahs where their animals graze. Some fires are started to stimulate new growth of nutritious grass for their animals, others are used to control the numbers of parasitic ticks or manage the growth of thorny scrub.

Without fires, many savannahs (and the animals they support) wouldn’t exist, and lighting them is a key management activity in many of the iconic protected areas of Africa. For instance the Serengeti in Tanzania is known worldwide for its safari animals and awe-inspiring wildebeest migration – and our work shows that around half of its grasslands burn each year.

Travel Journeys: ‘Ashio, Japan’ – Return To Forests

Dig deeper into the story of Ashio, a former mining town in Tochigi Prefecture that’s returning to nature with the passage of time and contributions of hard-working residents.

[Skip Intro] 1:59

The Ashio Copper Mine (足尾銅山, Ashio Dōzan) was a copper mine located in the town of Ashio, Tochigi, (now part of the city of Nikkō, Tochigi), in the northern Kantō region of Japan. It was significant as the site of Japan’s first major pollution disaster in the 1880s and the scene of the 1907 miners riots. The pollution disaster led to the birth of the Japanese environmental movement and the 1897 Third Mine Pollution Prevention Order. The pollution incident also triggered changes in the mine’s operations that played a role in the 1907 riots, which became part of a string of mining disputes in 1907. During World War Two the mine was worked by POW forced labour.

Conservation: Mapping ‘The Great Barrier Reef’ To Help It Survive (BBC Video)

The Great Barrier Reef is the world’s largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres over an area of approximately 344,400 square kilometres. The reef is located in the Coral Sea, off the coast of Queensland, Australia. 

Sustainable Foods: Inside A ‘Wind-Powered Vertical Farm’ In Denmark (Video)

Inside a warehouse in an industrial zone in Copenhagen vast stacks of plants soar almost to the ceiling. In time, this newly opened vertical farm will be one of the largest in Europe, while power from Denmark’s windfarms will ensure it is carbon-neutral, according to the company behind it.

Wildlife: ‘Return Of The Reds’ – Rewilding Red Squirrels Into Scotland

Red squirrels are receiving a helping hand in reclaiming lost ground. A partnership between Trees For Life and The Woodland Trust is returning red squirrels to Ledmore and Migdale woods in Sutherland.

Ecology: Wildfires Kindle Natural Biodiversity

Raging fires throughout the U.S. and Australia over the past year have put vulnerable species at risk. But not all blazes are devastating—in fact, fire can promote biodiversity. In grasslands, fires prevent trees and roots from taking hold. This allows grazing animals the space and vegetation they need to thrive. As the pattern of wildfires changes, a new review in Science outlines effective ways to let natural fires burn, while preventing out-of-control blazes. Watch to learn how a few of these techniques have been applied around the world.

Wildlife Video: ’24 Hours On Earth’ – In One Image

“Nature reveals itself to us in unique ways, if we stop and look at the world through a window of time,” says photographer Stephen Wilkes. Using a special photographic technique that reveals how a scene changes from day to night in a single image,

Wilkes exposes the Earth’s beautiful complexity and the impacts of climate change — from the disruption of flamingo migrations in Africa to the threat of melting ice — with unprecedented force. This performance was part of the Countdown Global Launch on 10.10.2020.

Countdown is TED’s global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world.
