How can farming adapt to a changing climate? A new study explores gaps in traditional thinking about farmers’ adaptations and proposes a new way to assess a farm’s vulnerability to climate change. This new framework is a first step toward preparing agriculture for an uncertain future.
Coastal wetlands provide invaluable ecological and economic services for our coastal communities. To keep pace with sea level rise, these habitats need space to migrate upland. This may present a challenge in some highly urbanized areas. A recent study that calculated open and developed land near wetlands along the Southeastern coast of the United States sheds light on the fate of coastal wetlands at a regional scale, and provides context for improved coastal resilience efforts.
One-third of the world’s food is lost or wasted. But the biggest loss, not included in this estimate, may be through our dietary choices. Consuming meat entails significantly more food loss than consuming plants directly. Favoring plant-based diets in America would produce enough food to feed 350 million additional people – more than would be fed if all conventional food supply chain losses were eliminated.
Droughts and extreme flooding have devastating effects in India’s rice-growing areas. New research shows that female farmers are using their ancestral knowledge and promoting a culture of sharing to help their crops adapt to climate change while keeping their families alive.
Climate change is already wreaking havoc on the world’s oceans. New research suggests that managing fisheries with climate change in mind could preserve this important food source for future generations.
Groundwater managers have a difficult time getting a sense of how much water farmers and urban water users extract from aquifers. Gravity Recovery and Climate Experiment (GRACE) is a satellite technology that uses microwaves to generate data that researchers use to build Earth gravity models. The models produced from GRACE data help water managers know how much water farmers and urban water planners have withdrawn from the ground. This helps communities manage their groundwater resources sustainably.
By 2050 two thirds of the world’s population will live in urban areas. This growth will cause an 80% increase in city water demand. To fulfill this growing need for water in cities, water will be taken away from rural and agricultural needs.
In the United States alone, beef production accounts for twenty percent of greenhouse gas emissions and it is the least efficient source of protein production. Americans will continue to eat beef; so designing a sustainable industry is essential to reducing emissions. In a new study, scientists explore two straightforward ways to achieve a sustainable industry – all without sacrificing your cheeseburgers.
Across the globe, rangelands are rapidly changing due to human-caused disturbances. New research shows that in Australia, livestock grazing is shifting the balance of plant diversity in favor of non-native species. This could pose serious conservation challenges for Australian rangelands in years to come.
Humans have long looked to the ocean for opportunities, sustenance, and growth. Today, advocates of “Blue Growth” aim to foster sustainable economic growth in the marine sector. Absent in the grandiose vision, however, is where our interaction with the ocean first began: fishing. Global fisheries production has stagnated: ecology is fragile, regulations are strict, and fish prices are low. So, what is the future for marine fisheries? What will be its role in Blue Growth?
