Informal settlements and climate change: An opportunity and challenge for cities of emerging economies

By Mayor Mpho Parks Tau of Johannesburg The unprecedented growth of cities in emerging economies, coupled with the legacy of apartheid in South Africa has, since the early 1990s, led to a rapid increase in informal settlements, or slums, in Johannesburg. As the economic heartland of South Africa, it is estimated that Johannesburg receives more…

Plastic: The big breakup

Co-authored by Erica Cirino My dog Foosa and I step onto the beach, and in the first few steps I find—as usual—something made of plastic.

Forests in 25 Words or Less

By Alison Clausen

Today marks the U.N. International Day of Forests. I was asked recently for an “elevator pitch” in 25 words or less on why we should invest resources in saving tropical forests and, in particular, in tropical forests in Madagascar. To those of us working in conservation, this question seems like a no-brainer, so at first I took the question with a grain of salt. However, my questioner persisted and it made me realize both that it is not a no-brainer for everyone – particularly given the competing priorities for peoples’ attention – and that for the conservation community we need to be able to answer such questions if we are to engage people in our work.

Fish Spawning Aggregations: an illusion of plenty

Spawning aggregations are massive gatherings of fish for breeding, a behavior shared by many species across the globe in many different habitats. They are predictable because they usually happen at the same place and at the same time each year, and humans have taken advantage of this to harvest large numbers of fish with minimal effort. But as harvesting keeps growing, fish populations keep diminishing.

The New Sustainable Development Goals: a Vision for Living in Harmony with Nature

There is now clearer recognition that sustainable development and biodiversity conservation are inextricably linked and that one cannot succeed without the other. The UN’s new Sustainable Development Goals address conservation of both terrestrial and marine ecosystems. The new agenda specifies that UN member states will “conserve and sustainably use oceans and seas, freshwater resources, as well as forests, mountains and drylands and to protect biodiversity, ecosystems and wildlife.” And SDG targets specifically refer to endangered species, calling for an end to wildlife poaching and trafficking.
