The Great Green Wall: Africa’s big plan to fight climate change

Sustainable Leaders | Africa, 12th July, 2022

Forty-six percent of African land is degraded. In an attempt to combat this desertification, along with all of the socio-economic issues that come with it, the African Union began the Great Green Wall initiative. For the past 15 years, Africans have been planting trees across 8,000 kilometres of the continent and hope to continue to ‘re-green’ its landscapes.

Bring back the super-spreaders: How reintroducing howler monkeys can pave the way for seed dispersal

Environment | Forests, June 5th, 2022

In the 2010s, the locally extinct brown howler monkey (Alouatta guariba) was reintroduced to the Tijuca National Park in Rio de Janeiro, Brazil. This reintroduction demonstrated the importance of primates in seed dispersal and how the absence or presence of a single species has the potential to reshape an entire ecosystem.

The threat of ‘supertrawlers’ to cetaceans

Environment | Oceans, December 30th, 2021

‘Supertrawlers’ are large-scale commercial fishing boats that trail nets the size of 450 tennis courts. The gaping maw of a supertrawler net is the length of seven blue whales, and when it sweeps the ocean depths, it captures large quantities of marine wildlife—not just its intended fish species.

Biomimicry: how nature can inspire a sustainable world

Sustainable Leaders | Global, October 28th, 2021

From the complex colonies of ants to the very bones inside our bodies, so much can be learned from natural systems and applied to human life. Biomimicry can be an effective tool for innovation and creating a more sustainable future.

Idiopathic Pulmonary Fibrosis: yet another lung disease made worse by air pollution

The buzz for green cities: urban spaces for people and pollinators

Sustainable Leaders | Global, July 11th, 2021

The COVID-19 pandemic has shown many city-dwellers tucked away indoors the enormous mental health benefits of spending time in nature. And as urbanisation takes over the world—with 5.2 billion people estimated to live on 1.9 million kilometers-squared of urban land by 2030—it is increasingly important to design city spaces to accommodate for the health of their inhabitants, both human and animal.
