Governments and funding bodies are increasingly evaluating the ‘impact’ of academic research. There are growing discussions about impact – what it means, and how it can be demonstrated – and it is a challenge to evaluate impact on society. This study investigated the broader benefits of scientific research, beyond technology development, to support more comprehensive evaluations of science.

The Alang-Sosiya shipbreaking yards in India highlight the inequalities and opportunities of global waste management. The yards, which recycle retired ships from more economically developed countries, have dramatically altered the ecosystems and social structures of the local area. A study looking at stakeholder perceptions analyses different positions on the social and environmental impacts of the yards.

The uncertain economic climate has severely affected companies’ decisions on whether to renew Eco Management and Audit Scheme (EMAS) certification in Spain, a recent survey indicates. The study suggests that a company is less likely to renew if initial certification was mainly motivated by government subsidies and grants than if certification is believed to improve business performance.

Extended producer responsibility (EPR) and other regulatory influences are essential to battery recycling in Finland, a new study finds. The researchers compare this with the situation in Chile, where a lack of appropriate legislation prevents recycling companies from overcoming the technical and financial challenges of battery recycling. The study helps policymakers understand how political, social, and cultural factors can support companies in their move towards circular-economy business models.

Insights from a recent Italian study could help local authorities across Europe improve their rates of separate waste collection for recycling. The researchers found higher rates of separate waste collection in municipalities with high-quality governmental institutions for waste collection, non-mountainous terrain and higher income levels. Separating household waste into streams, such as glass or food, for re-use and recycling helps free up resources for a circular economy. Good-quality institutions are the main driver of separate waste collection and can overcome barriers such as low economic prosperity.

Water extraction from the ground using pumps and wells may have significant impacts on the flow of water in streams on the surface, according to new research. Results suggest that groundwater pumping has caused total stream flow in one Hawaiian stream to decline by 5.4mm per year since 1960.

A new study has estimated the water consumption and land use for the production of 160 crops that constitute most of the world’s cropland. The results suggest that, collectively, wheat, rice, cotton, maize and sugar cane account for 49% of water scarcity and 42% of land resource stress caused by worldwide crop production.

Desalination plants, powered by wind energy, offer the potential to produce freshwater using a renewable source of energy. A recent study has explored some of the challenges of integrating wind energy with desalination units, and suggests combining wind with other forms of renewable energy, or constructing a system that operates with variable energy input would help overcome problems with wind powered desalination.

A recent study has revealed how water use has changed across the world over the last 60 years. Growing populations and economic development, particularly in newly-emerging countries, have increased water demand, but technological developments have led to water efficiencies and savings, which moderate these demands.

The impact of shale gas development on surface water quality has been explored in a recent study. Focusing on the Pennsylvania portion of the Marcellus Shale formation (which stretches from West Virginia to the Canadian border), the researchers conclude that shale gas wells and the treatment of shale gas extraction waste have measurable impacts on downstream surface water quality.

Water resource management needs to adapt to changes in climate, water demand and land use. A new tool has been developed by the LIFE+ Water Change Project to assess these ‘global change’ impacts on water resources and inform decisions on optimal adaptation strategies. A recent study has applied the tool to a river basin in Spain.

Moderate levels of nitrogen in streams and rivers can make it difficult to assess the effects of pesticides on aquatic wildlife, because nutrients mask the pesticides’ impacts, according to recent research. This highlights the importance of considering nutrient levels when developing measures to protect aquatic ecosystems.

Climate change will substantially increase the severity and length of droughts in Europe by the end of the century, according to new research. The study showed that some European countries could experience a reduction in river flow of up to 80% by the 2080s.

Funding for scientists, planners and inspectors should be available before any shale gas development begins, a new review recommends. As revenue for such staff is often provided by the development itself, planning, which is vital to provide immediate environmental protection as well as monitoring long-term impacts, is neglected. The researchers also advocate the use of 'adaptive management' as a decision-making framework for this complex issue.

Small field wetlands are a simple and effective way to reduce soil erosion and nutrient pollution, recent research suggests. The authors adapted Norwegian designs for the UK environment and created a series of small rectangular lakes on the edges of agricultural fields. After three years, the wetlands had prevented tonnes of soil from leaving the land, and helped alleviate some of the nutrient run-off that would have affected neighbouring waterways.

Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the devices, as well as improving mooring and foundations and deploying devices further out at sea, will help to further reduce the life-cycle environmental impact of ocean-energy systems, according to the study.

Landfill leachate is the liquid that seeps through or out of waste deposits in landfill sites. EU regulations, such as the Landfill Directive1, have significantly reduced the volume of leachate produced, a study on leachate management in Ireland has found. Leachate, mainly from younger landfills in Ireland is, however, stronger since implementation of the legislation, and the researchers say the future treatment of leachate under stricter environmental protection regulations will continue to be a long-term concern for landfill operators and regulators.

Rajasthan to create a common data and analytics platform for all government departments across the State to collate and utilize data more effectively and efficiently, improving the delivery of citizen services with the help of Teradata solutions.

As part of the partnership with the Guiyang Municipal government, agreements worth 25 million Yen between Chinese customers and Indian service providers are also going to be announced.

Xiaomi's arch rival, Madhav Sheth-led Realme, has revealed plans to become a tech-lifestyle company in India next year, with introducing a bouquet of IoT products. Others are following suit too. Xiaomi has already shared how its AIoT (AI+IoT) dual strategy is going to shape its product vision.

DBS Bank is leveraging technology to reduce man hours, enhance the customer journey, automate processes and open new revenue streams.

A new global study on the economics of ecosystem services and biodiversity loss suggests that governments can achieve more resilient economies and receive higher rates of return on their public investment strategies when they recognise and target the value of ecosystem services.

New EU-supported research in the Mediterranean Sea has assessed the impact of fish-farming on seafloor ecosystems. Results indicate that impacts are only apparent in habitats with no vegetation, but the researchers suggest that habitats with vegetation seagrass could be masking the effects.

A new study has compared conservation projects that focus on promoting only biodiversity with projects that focus on promoting both biodiversity and ecosystem services. The results dispel several myths surrounding ecosystem service projects and indicate they are as effective at addressing threats to biodiversity as their biodiversity counterparts.

Researchers have developed a new cost-effective tool to assess the impact of policy on biodiversity at a European scale. The study used it to assess the policy of expanding woody biofuel plantations in the EU, which indicated that 28 per cent of wild species would be negatively affected and 10 per cent would experience beneficial effects.

A new study of European river restoration projects has indicated that their impact on the physical characteristics of rivers depends on the region, river type and restoration approach. However, regardless of the river, region or approach, impacts on the biodiversity of riverbed species is limited. Larger scale projects could be more effective.

'Game theory' is a mathematical framework that aims to predict the performance of individuals or groups by considering the interaction between them. New research has applied game theory to three different cases of biodiversity conservation to predict conflict and offer broad suggestions for overcoming disagreements.

Mosses are an important but sometimes overlooked group of plants, which play a significant role in cycling in carbon and nitrogen between the land and the air. A new study proposes that scientists could use mosses as a model to investigate the impacts of environmental change on biodiversity and nature.

Researchers have recommended new, improved ways of increasing the ecological value of European grasslands. Plant diversity ??? or species richness ??? can be increased by a factor of three through sowing grass and wildflower seed mixtures, together with a carefully controlled plan for animal grazing.

The Chernobyl nuclear disaster is still having an impact on local biodiversity more than 25 years after the event, according to a new study. Researchers in France and the US suggest that rare bird species have been particularly affected by the accident and that genetic changes in plants and animals caused by radiation are being passed down the generations.

A study on the effects of noise pollution from natural gas wells in the US reveals that it may have reduced the number of young trees growing locally by changing the types of animals that visit the area. However, in the same woodland environment, flowering plants pollinated by hummingbirds seem to benefit from the noise.

Insect communities are permanently changed by the presence of street lighting, according to new research. The authors of the study found that predatory and scavenging insects such as ants and ground beetles were more common under streetlights at all times of day, suggesting that light pollution does not simply attract different types of animals at night.

The damaging impacts of the invasive alien plant, the giant hogweed, decline over time, new research from the Czech Republic has concluded. Although this plant initially reduces the native species richness of the grasslands it colonises, the study found that numbers of native species increased again in sites that had been colonised by hogweed for 40 years or longer.

Moose avoid roads during day when human activity is highest, new research suggests. Monitoring moose movements in Sweden, researchers have found that the probability of moose being near roads drops after 06:00 and only rises again at approximately 18:00.

A briefing document, providing policymakers with key information on environmental impact assessments of deep-sea mining, has been published. The authors describe the Environmental Impact Assessment (EIA) process in detail to aid management and policy decisions regarding these sensitive habitats.

Depositing dredged material on the seabed can significantly reduce the functioning of marine habitats, diminishing the amount of food available for fish and other animals further up the food chain, new research suggests. The author of the study calls for inclusion of this effect into environmental impact assessments of dredging.

A case study in Sweden has shown that critically endangered European eels are being lost when they are sucked into the local nuclear power station???s cooling system. A process to pump the eels back into the sea could be beneficial to this species, the researchers conclude.

Seagrass restoration projects could effectively mitigate climate change, capturing up to 1337 tons of CO₂ per hectare after 50 years, new research suggests. If a carbon tax system was in place, the researchers add, these schemes would likely provide returns at least equal to the initial investment needed, assuming the tax was set at an appropriate level.

Researchers have developed a new risk assessment scheme for invasive alien species that not only predicts their direct effects on biodiversity, but also their impacts on ecosystem services. Furthermore, the scheme allows sources of uncertainty in a species??? impact to be identified, and can be applied to a range of different species.

Ocean warming driven by climate change will reduce the amount of food reaching marine life on the seafloor, a recent study suggests. This would result in a 5.2% global reduction in seafloor biomass by the end of the 21^st century and biodiversity hotspots, such as cold-water coral reefs, will be particularly badly affected, say the researchers.

The importance of 'stepping stone' patches of habitat for biodiversity has been underestimated, a new study suggests. The researchers developed a new connectivity model, which better captures the effects of stepping stones on species movement.

Trawling's impacts on marine ecosystems can be assessed using simple metrics which characterise easy-to-obtain samples of fish, new research suggests. The Portuguese study shows that groups of fish become dominated by fewer species as fishing intensity increases, while their total biomass declines. Moreover, in the most fished areas there were other noteworthy changes, such as substantial reductions in the proportion of sharks and rays.

How do offshore wind farms affect marine wildlife? A new study outlines a systematic approach developed for Swedish waters that could also be useful for assessing wind energy impacts on the marine environment more widely.

A new approach to predicting whether a degraded ecosystem can be successfully restored is presented in a recent study. The researchers who developed it show how it works with the case of peatland restoration. Their method uses a computer model to link restoration success or failure with plant species and management techniques on the sites.

Research findings on the wildlife and habitat impacts of unconventional shale gas and oil developments in the US have been collated in a new review. Its authors stress the importance of collecting data on local ecosystems before such developments begin, to allow changes in nature be tracked and aid on-going improvements to management.

Roads reduce the species diversity and distribution of frogs and toads, a new US study reports. The large-scale study used data from a national citizen science programme in which members of the public help monitor amphibian populations.

Virtually sea ice-free summers since 2005 have forced an important Arctic seabird species to change its foraging grounds and prey, new research shows. The body mass of the little auk — the most abundant seabird in the Atlantic Arctic — has shrunk by 4% in the past 20 years in one of its Russian breeding grounds, the study found. This change may be caused by its new foraging behaviour.

Hunting has obvious impacts on wild populations. However, new research concludes that for Scandinavian brown bears (Ursus arctos), it also contributes to the killing of cubs by adult males to increase the male's chances of mating with the cubs' mother. The researchers say that this indirect effect of hunting should be considered when developing sustainable hunting quotas and management plans.

The effects of changing agricultural practices on farmland birds are explored in a recently published study from Sweden. Overall abundance of 16 common species declined by 23% between 1994 and 2004, which may be partly caused by changes in land use, such as an increase in the amount of wheat cropland. However, effects vary between species, and some species increased or stayed stable in number.

Adapted habitat equivalency analysis (HEA) may help decision makers select projects to restore damaged ecosystems under a limited budget. HEA, used to assess damages to natural resources, can help to clarify objectives and compare trade-offs between projects to choose the most cost-effective among them, according to this study’s authors.
