Some Niger Delta residents are less concerned about oil-induced hazards and risks, or floods and erosion. They are more worried about a lack of sanitation amenities.
As sea levels rise, this natural form of beach replenishment might be an important factor in offsetting some of the damaging effects of climate change on beaches.
If the world overshoots its climate targets, drought could cause dryland areas to expand by a quarter and encompass half the Earth’s land area, threatening lives and livelihoods.

Around the world, fragile coastal ecosystems are under intense pressure, and understanding and managing their complex interactions requires an integrated and interdisciplinary approach.
Healthy soils are vital for food, biodiversity, and a healthy planet, but this below-ground world is often overlooked. The launch of the State of Knowledge of Soil Biodiversity Report highlights this.
Almost a century ago, New Zealand and Australia were at the forefront of an environmental crisis that forewarned of humanity’s global impact – erosion. It left its mark on culture.
There’s growing interest in making the US food system more resilient and flexible, but soil – the origin of nearly everything we eat – is often left out of the picture.
‘Building back better’ refers to making communities more disaster-proof and resilient after they take a hit. But instead, some US owners are building back bigger homes in vulnerable places.
A new report predicts that one-third of the ice in the Himalayas will melt, even if we contain global warming to 1.5C. So what does that mean for the flood-prone valleys below?
