A new study claims that fossil fuel subsidies are a burden for national budget and for the environment. Carbon pricing should be introduced, instead, as a solution to drastically reduce CO2 emissions and obtain financial resources to address sustainable development.
Cities as ecosystems? The benefits of this approach are manifold, including water purification, improved public health, reduced disaster exposure, enhanced resilience and social justice. But to move cities – and so the planet – into a sustainable future, this approach must become more integrated and pragmatic, and applied also in the global south, says on Nature Xuemei Bai, professor at the Fenner School of Environment and Society, Australian National University in Canberra.
Since 1961 the annual global growth in fish consumption has been twice as high as population growth, demonstrating that the fisheries sector is crucial in meeting the goal of a world without hunger and malnutrition. Data and in-depth analyses on global fish production, consumption and marketing rates, together with some first attempts at quantifying the possible future scenarios regarding the linkages of fisheries and aquaculture both to climate change and to other challenges, such as pollution. The current state of these two key sectors worldwide up to 2018 in the new FAO report.
How do we meet the hunger, poverty, energy, growth goals while meeting the environmental goals? What are the synergies and trade-offs? What are the costs
There are growing threats to oceans, yet positive trends are kicking in, and prospects may be more optimistic than the current figures suggests. “We have a plan,” – United Nations Special Envoy Peter Thomson explains to Foresight – “and we are working to put it into practice.”
Oceans are facing increasing pressures: biodiversity loss, pollution, over-exploitation and illegal activities; and diverse impacts of climate change, such as ocean warming, acidification and rising sea level, are increasingly alarming. From the headquarters of international organizations as well as in the most vulnerable and ocean dependent countries, it is acknowledged that it is time to change the way we manage oceans and their resources in order to keep them healthy, productive, safe, secure and resilient.
Despite real progress being made in access to electricity in least developed countries and industrial energy efficiency, global trends show that the world is not on
