Sustainable Resource UK’s first high-detail atlas links local environment to health Map takes in factors from sunshine duration to air pollution to flag up disparities By Stuart Qualtrough R esearchers have launched the UK’s first detailed atlas linking environment and health maps at a fine scale across England and Wales. Produced by the UK Small Area Health Statistics Unit (SAHSU), part of the MRC-PHE Centre for Environment & Health based at Imperial College London, the openaccess atlas allows researchers, policymakers and members of the public to study the geographical pattern of 14 diseases and conditions such as lung cancer, breast cancer, heart disease, leukaemia and low birth weight. Alongside this it provides maps of geographical variations of selected environmental agents such as air pollution, sunshine and pesticides. Simply comparing the health and environment maps will not enable people to conclude there is Atlas links health risk with the envionment for the first time in the UK a causal link between a specific environmental agent and a health condition, but it can highlight areas for future research. For example, the atlas shows that skin cancer risk is greatest in southwest England even though sunshine duration is highest in southeast England. This could trigger further research into behavioural differences between the areas to explain this variation. This atlas is the first in the UK to adjust for both age and deprivation as well as making statistical allowance if numbers of cases are very small. Looking across all health conditions there are 33 wards that show more consistent patterns of lower relative health risks compared to only eight at the higher end of health risk. Those areas that appear to have the lowest relative risk are in central London, North Norfolk, parts of Suffolk, and Brighton & Hove. The areas with the higher relative risk tend to be in the North West, parts of Yorkshire and South Wales. Some conditions show a lot of geographical variation that can’t be explained by deprivation or ageing. Examples are lung, skin and liver cancers, chronic pulmonary disease and mesothelioma (a cancer caused by exposure to asbestos). In particular the risks for respiratory problems, such as lung cancer and chronic pulmonary disease, are worse in urban areas. Risks of heart disease mortality are predominantly higher in the north of the country. However, the relative risks of breast cancer, prostate cancer, leukaemia, brain cancer, still births and low birth weight are more similar across Wales and England. Sustainable Energy Solar farms could create biodiversity hotspots, benefiting British wildlife for decades By Stuart Qualtrough Solar farms could become havens for plants and wildlife and help reverse declining numbers of bumblebees, following the publication of new industry guidelines to support biodiversity. The expert guidance on how to boost nature on solar farms was launched this week by the BRE National Solar Centre (BRE NSC). The guidance has been authored by ecologist Dr Guy Parker in partnership with leading UK conservation groups and the Solar Trade Association (STA). Solar farms typically take up less than 5% of the land they are on, leaving huge scope to Report helps solar support nature develop protected habitats to support local wildlife and plant life. Many species benefit from the diversity of light and shade that the solar arrays provide, including bumblebees. The 12-page report states: “Solar farms present an excellent opportunity for biodiversity. In most solar farms panels are set on piles and there is minimal disturbance to the ground. The panels generally have no moving parts. “Normally only 25-40% of the surface is over-sailed by panels. Because panels are raised above the ground on posts, more than 95% of the field is still accessible for plant growth and potentially for wildlife enhancements and in some cases complementary agricultural activities such as conservation grazing. “Following construction, there is little human activity apart from occasional maintenance visits. Most sites have a lifespan of at least 20 years which is sufficient time for appropriate land management to yield real wildlife benefits. “A number of options exist for enhancing biodiversity on solar farms, from hedgerows to field margins to wild flower meadows to bird boxes and ponds. Each site is unique and there is no ‘one size fits all’ solution. Ultimately the best plans will be those developed through engagement with the local community, the landowner and local and national conservation organisations.” Jonny Williams, Associate Director of the B I
