Images created by NASA with satellite data helped the U.S. Department of Agriculture analyze outbreak patterns for southern pine beetles in Alabama, in spring 2016.
Big data open-access publishing and other advances offer ecologists the ability to forecast events like pest outbreaks over days and seasons rather than decades. But scholars need to seize this opportunity.
Since 1800, the world’s population has multiplied seven and a half times.
The world’s population has reached 7.5 billion and is expected to climb to nearly 10 billion by 2050. Why will population growth inevitably continue? Should we try to reduce or stop this growth?

Victoria’s mountain ash ecosystem is vulnerable to collapse.
From fisheries to forestry, there's a pattern to collapsing ecosystems and industries. If we can predict them, maybe we can avoid the damage.
Mexico has a lot of natural beauty to save – or squander.
The government has decided to protect vast new expanses of land and sea. But bad planning and lax regulations are likely to limit, or even undermine, this conservation effort.
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.
The impact of small businesses on the environment has largely been ignored, but getting them to implement environmental management systems won't be easy. This is because of their culture of resisting red tape and the way they operate.
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.
