Fishing boat XTK191, known as Home Boy, returned to Kivukoni fish market in downtown Dar es Salaam at dawn one day last week. The 15 young men on board the old dhow dropped anchor and heaved their catch over the side for others to run it across the beach to where hundreds of traders milled. […]
In America today, it’s rare to see political leaders respond to a threat with an appropriate evidence-based policy solution. At the national level, more often we see actions that aggravate existing problems or create new ones. California – the country’s most populous and economically powerful state – has been a welcome exception. California has been […]
Europe’s animal farming sector has exceeded safe bounds for greenhouse gas emissions, nutrient flows and biodiversity loss, and urgently needs to be scaled back, according to a major report. Pressure on livestock farmers is set to intensify this century as global population and income growth raises demand for meat-based products beyond the planet’s capacity to […]
California is set to launch a satellite to track greenhouse gases, as former US Secretary of State John Kerry and island nation leaders warned that the world is far off course to avoid the worst effects of rising temperatures. Gov. Jerry Brown announced plans for the satellite on the last day of a climate change […]
IIASA researchers have developed a general decision-making framework to support policy decisions on the management of water resources, which, for the first time, explicitly takes into account the associated uncertainties. Reliable access to clean water is one of the key aspects addressed by the UN Sustainable Development Goals (SDGs). In fact, most of the SDGs […]
Globally, forest trees are increasingly at risk from habitat destruction, pests and disease, and a changing climate. But the guidelines for effective preservation of a tree species’ genetic diversity and adaptive potential have been limited to simple mathematical equations for crop collections from the 1970s, or best guesses based on intuitions. Globally, forest trees are […]
The Arctic is rapidly warming, with stronger effects than observed elsewhere in the world. The Arctic regions are particularly important with respect to climate change, as permafrost soils store huge amounts of the Earth’s soil carbon (C). Warming of Arctic soils and thawing of permafrost can have substantial consequences for the global climate, as the […]
Bleaching events caused by rising water temperatures could increase mortality among a coral species already threatened by disease, says new research by Mote Marine Laboratory and Penn State, US, published in eLife. The study on the species Acropora cervicornis, known as the staghorn coral, emphasizes the need for maintaining genetic diversity while at the same […]
Shifting to a healthy diet is not only good for us, but it also saves a lot of precious fresh water, according to a JRC study. Compared to existing diets, the water required to produce our food could be reduced by between: 11% and 35% for healthy diets containing meat, 33% and 55% for healthy […]
Many of the world’s future farmers will likely be farming oceans, as aquaculture – the cultivation of fish and other aquatic species – continues its expansion as the fastest growing food sector. New research shows that in order for this next generation of farmers to thrive, there is an urgent need to prepare them for […]
