Around the world, cities endeavour to cut greenhouse gas emissions, while adapting to the threats – and opportunities – presented by climate change. It’s no easy task, but the first step is to make a plan outlining how to meet the targets set out in the Paris Agreement, and help limit the world’s mean temperature rise to less than two degrees Celsius above pre-industrial levels.
About 74% of Europe’s population lives in cities, and urban settlements account for 60-80% of carbon emissions – so it makes sense to plan at an urban level. Working to meet carbon reduction targets can also reduce local pollution and increase energy efficiency – which benefits both businesses and residents.
But it’s just as important for cities to adapt to climate change – even if the human race were to cut emissions entirely, we would still be facing the extreme effects of climate change for decades to come, because of the increased carbon input that has already taken place since the industrial revolution.
In the most comprehensive survey to date, we collaborated with 30 researchers across Europe to investigate the availability and content of local climate plans for 885 European cities, across all 28 EU member states. The inventory provides a big-picture overview of where EU cities stand, in terms of mitigating and adapting to climate change. Continue reading →
UK peatlands are wild, often remote places. These aren’t the fields and farms that many town dwellers associate with the British countryside, rather areas of bog and mire that may be seldom visited except, perhaps, by the committed enthusiast. Not all look as attractive as they might — all too often peat bogs have suffered extensive damage, either through extraction of material for gardening products or attempts to drain the land for agricultural purposes. But these are important places, providing not only iconic and beautiful habitats for other species, but also vital resources for our own survival.
What have peat bogs got to offer? Our supplies of clean drinking water depend on rainfall in peatlands and they can also be important in mitigating flooding , slowing down the flow of water on its way to urban areas. Highly specialised species that are often rare, threatened or declining live, feed and breed in peatland habitats. From the bog hoverfly to the golden plover and greenshank, many species make their home here.
World Water Day is about taking action to tackle the global water crisis and ensuring adequate water for food production is another important aspect of water security. Researchers at Newcastle University are currently working on a project that will help to ensure that small holder farmers in South Asia have enough water for their crops into the future.
The work of Professor Hayley Fowler and Dr Nathan Forsythe, builds upon multiple collaborative initiatives with research institutes in South Asia, and focuses on finding grassroots-scale solutions to mitigate drought impacts on local communities and build resilience to climate change impacts. The project looks at ways to mainstream climate adaptation in three countries across South Asia with case study villages in contexts such as the rural areas of Nainital district in Uttarakhand state, India. Similar focus areas will be selected in Pakistan and Sri Lanka.
The project focuses on translation of sophisticated climate model outputs into pragmatically useful “climate services” that help communities prepare for climate change, and understand its effects on crop yields at the local level. Cropping simulations generated from large-scale regional climate models will be refined based on information generated by the smallholder farmers themselves.
On this planet humans are radically changing the land, air and water. In many cases this is unavoidable. All species have some degree of impact on the environment in which they live, but in the case of humans it is magnitudes greater. We are now the force driving environmental systems which has led to a new geological epoch — the Anthropocene.
During the preceding geological period (the Holocene) the planet’s climate was getting cooler but since human intervention it’s heating up at a faster rate than we have ever experienced before. We are releasing enough greenhouse gas emissions in the atmosphere that it is intensifying the hydrological cycle, leading to more rainfall in some areas, and making others dryer. But it’s not only the climate we’re changing. Humans are moving around more sediment (silt, sand, gravel etc) than all the rivers, ice sheets and desert winds in the world combined. We are a geological force to be reckoned with. Continue reading →
