Think of all the resources needed to transform Shenzhen, a fishing town 35 years ago, into a megacity of more than 10 million people.
Our cities need to become much more efficient not just to conserve precious resources but to improve the economy, wellbeing and resilience to environmental change and disasters.
Hundreds of small-scale miners are scraping out tiny quantities of increasingly precious gold in El Corpus, southern Honduras.
Are high levels of violence and displacement in Central America and Mexico caused by natural resource exploitation?
There’s too much focus on the footprint of large businesses on the environment, leaving small businesses out.

While politicians like Malcolm Turnbull and Barnaby Joyce do the traditional photo-ops, fewer people than ever are taking on farming, which can no longer support vibrant rural and regional communities on its own.
What are the issues facing rural and regional Australia? The challenges are many and varied – and only some have made the national political agenda – but these areas deserve better than neglect.
Many developing countries are highly urbanised but lack large industrial sectors.
Developing countries, specifically in sub-Saharan Africa, are urbanising without industrialising, a trajectory that leaves them with relatively higher poverty rates and share of slums.
The need for a solution to e-waste disposal is more urgent than ever.
