Coastal areas in West Africa are under intense pressure from demographic growth, economic expansion and ongoing climate change.
Around the world, fragile coastal ecosystems are under intense pressure, and understanding and managing their complex interactions requires an integrated and interdisciplinary approach.
An increasing number of farmers in China are cutting back on fertilizer and pesticide use.
This transformation provides lessons for the rest of world, for shifting away from chemical agriculture towards a healthier system for people and the planet.

Scientists are predicting major algae blooms in Lake Erie and large dead zones in the Chesapeake Bay and Gulf of Mexico this summer. Nutrient pollution from industrial corn farming is a major driver.
Feeding pigs seaweed could make them, us and the planet healthier without contributing to antibiotic resistance in bacteria.

Excess nutrients from farm fields cause widespread water pollution across the U.S. Bioreactors – essentially, ditches filled with wood chips – are emerging as a way to reduce nutrient pollution.
Climate change is warming Lake Tahoe and could alter its chemistry in harmful ways.
Lakes contain most of the fresh water on Earth’s surface. Recent research at Lake Tahoe in the Sierra Nevada mountains shows that climate change could alter lake chemistry, threatening these sources.
Our thinly spread efforts to prop up the environment are failing and it is time for tough decisions about what we can realistically preserve.
Australian farmers take pride in their efficient and productive farming systems, competing in the global economy and without many of the large subsidies given to their counterparts in Europe and North…
