Climate change is affecting the health of people around the world; transitioning to net-zero emissions could be the greatest health opportunity this century
By Associate Professor Celia McMichael, Professor Kathryn Bowen and Professor Mark Stevenson, University of Melbourne
Climate change threatens to undermine the health of people around the world, with more intense and frequent extreme weather events, increased heatwave exposure, climate-related food insecurity, alteration in the spread of infectious diseases and exacerbated mental ill-health.
For many commercial and recreational fishers, marine protected areas (where fishing is excluded) are viewed with scepticism.
Critics have questioned the legitimacy of what is referred to as the spillover effect — where excluding fishing is hypothesised to produce ecological and/or commercial fishing benefits beyond the boundaries of the protected area.
Researchers compared catch rates outside the world’s largest marine protected area off Hawaii, before and after fishing was excluded
Yellowfin tuna catch rates were boosted by 60 per cent within 100 nautical miles of the boundary, and total “other” species were also higher
Increased tuna catch rates were seen for 300 nautical miles from the boundary
But research published today in Science suggests fishing exclusion zones can benefit both fishers and the marine environment, and that fish yields for some species can be boosted up to several hundred kilometres away from the protected habitat.
The British Ecological Society Policy Team is seeking authors to contribute to a new report on regenerative agriculture. The term “regenerative agriculture” is gaining traction and it is increasingly being used in different contexts with a variety of meanings by academics, policy-makers, NGOs and land managers. The lack of an agreed definition could result in a loss of credibility of the term, which could be used by companies to become more appealing to environmentally-aware consumers, with little scrutiny.
Many have suspected our dear Earth is hotter than ever — the NOAA has now presented data that statistically proves it. Last month was the hottest in recorded history and it seems this is a shadow of things to come… check out their summary with links to more details here.
