Science has guided national dryland policy in Africa through approaches that have omitted local knowledge, and has informed international policy through implementation of the United Nations Convention to Combat Desertification (UNCCD), previously developed by a Roster of Experts. Our national and district-level research in Botswana has identified routes to increase community involvement in degradation monitoring, and our strategies have been rolled out nationally via agricultural extension workers, allowing knowledge to inform farming practices and land policy. Our analysis of the wider international context has led us to propose new science-to-policy pathways that have allowed the UNCCD to draw more effectively upon both local and scientific evidence.
Between 1987 and 2011, the Fish group at Imperial College London assisted the Falkland Islands Government by providing fisheries management advice as well as delivering seasonal licencing and fee analyses which determined the number and type of fishing licences allocated to commercial vessels operating in Falkland waters. The work of the Fish group had unprecedented economic, commercial and environmental impacts on the Falkland Islands, where between 50% and 75% of the annual revenue required to fund all infrastructure, research and development in the Islands is generated by the £20M income from the sale of commercial fishing licences. In 2006, the Falkland Islands changed from a seasonal fishing licensing system to a rights-based management system of Individual Transferrable Quotas (ITQs) for fishing companies. The move to ITQs, which was recommended by the Fish Group, generated revenue of £9.5 million in 2010 and the system will remain in place until 2031. During a transition period between 2008 and 2011, the Fish Group supported the planned hand-over of licencing and fee responsibilities to the Falkland Island Fisheries Department which continues to use the bio-economic and stock assessment models developed by the Fish Group at Imperial for the sustainable management of marine resources.
Salmon maturation prior to harvest constitutes an environmental, welfare and production bottleneck for the salmon aquaculture industry. Our research has reduced the number of fish that mature during the grow-out phase so they do not reallocate energy to develop gonads and display secondary sexual characteristics that reduce yield, harvest quality and increase disease susceptibility that can result in downgrading at processing and lost profitability. In addition, reproductively competent fish that escape from on-growing cages may breed with wild stocks, leading to potential introgression. This has a major impact on public perception of farmed salmon and it limits the expansion of the industry. The IoA Reproduction team has undertaken a comprehensive body of work since 1993 to address this critical production bottleneck through an array of management strategies. This work culminated in the REF period by the demonstration that salmon puberty can be reduced to <3% by the use of standardised lighting regimes (2008) followed by the first commercial production of sterile salmon (2012-13).
Tilapia, an important farmed fish is of fundamental importance to the food security of poor people in less developed countries, and ensuring high quality juveniles are available locally is critical. Stirling's Sustainable Aquaculture group have been instrumental in developing a novel decentralised approach to sustainable tilapia farming which has now been piloted and scaled up in NW Bangladesh (NWB). This work has improved the availability of high quality seed and more efficient and productive food fish. This has led to seasonal income smoothing and elevated household nutrition among the targeted poorer households producing the juveniles, as well as reduced costs and use of agrochemicals in associated rice production. Landless people have also benefitted through trading fish in targeted areas and further afield.
Since 2008, the School of Environment & Life Sciences at the University of Salford has expanded its research in the field of population and conservation genetics, focusing on the application of molecular genetics and evolutionary theory on supporting the management of exploited living resources and conservation of endangered species and ecosystems. Molecular Ecology and Conservation demonstrates the following impact:
Increasing consumer awareness of the environmental implications of food choices, improving consumer confidence and food management policy, supporting environmental management and biodiversity, and guiding international conservation policy and management processes.
Effective, equitable natural resource management poses increasingly complex challenges for policymakers and local communities in the context of climate change, population growth and potentially conflicting agendas on biodiversity conservation, livelihoods and economic growth. Leicester research on socio-ecological, culturally appropriate approaches to environmental governance and sustainability has been integral to:
Researchers at the Hull International Fisheries Institute (HIFI) in the School of Biological, Biomedical and Environmental Sciences, have shaped policies that govern the regulation, conservation and enhancement of freshwater fisheries for national and trans-national governments and their agencies and institutions.
The reach of this research is international as it underpins fisheries policies and guidelines across Europe. Its significance is considerable because these policies regulate the sustainable use of freshwater fisheries; it protects them from alien and genetically-modified fishes; and they prohibit genetically-modified fish in Europe. Our research also shapes European legislation on controlling fish-eating birds. As a result this research has produced significant and broad impact.
This case study concerns the impact of Plymouth University research relating to farmed fish diets, which led to changes to EU legislation with respect to two types of ingredients: animal proteins and probiotics. The impact of the reintroduction of certain animal proteins in farmed fish feeds (previously banned to protect human health) and to the authorization of a probiotic as a feed additive, involved industry investment in research, have reduced the environmental impact of farmed fishing, improved competitiveness, enhanced yield and quality and improved fish health and survival.
Research at the University of Southampton into the behaviour of fish at dams has led to the improved design and positioning of screens to prevent economically important and endangered fish from being killed in turbines, as well as enabling them to pass barriers more successfully through improved fish passes. The research has informed practical changes to river infrastructure in the UK, Sweden, the USA, and China. It also led to development of methodologies for river restoration and planning which have aided the implementation of new conservation legislation, and quantification of the environmental impacts of beaver dams on fisheries.
Bangor Research since 1998 has pioneered, through experimental, comparative and modelling studies and industry collaborations, quantification of the wider ecosystem effects of fishing, specifically on seabed habitats. Novel findings gave policy and economic benefits to the fishing industry and led to the sustainable, continued profitable development of the UK's largest blue mussel fishery and Isle of Man scallop fishery, with a combined value of £22M. It directly led to Marine Stewardship Council (MSC) certification of these fisheries and underpinned certification of dozens of other demersal fisheries. Additionally, the research has influenced UK retailer policies on sustainable fish sourcing, providing direct environmental and commercial benefits and improving public knowledge and sustainable consumption.
