    GM Insects and Disease Control

    Insects play a critical role in ecosystems, but can also cause economic and social harm by transmitting diseases to humans and livestock, and damaging crops. Genetically modified (GM) insects could be used alongside other approaches to mitigate harms. This POSTnote summarises possible benefits, risks and uncertainties associated with their deployment.

    Diffuse Pollution of Water by Agriculture

    Water pollution regulation is devolved in the UK. Surface, coastal and ground waters in England suffer from significant pollution problems: 78% of surface and groundwater bodies fail to meet the ‘good’ ecological status prescribed by the EU Water Frameworks Directive. Pollution increases water treatment costs and adversely affects wildlife. Compared to treatment, preventing water pollution at source can have a cost-benefit ratio as high as 1:65. This POSTnote describes the contribution of agriculture to water pollution, and measures that can be taken to reduce it.

    Short Lived Climate Pollutants

    Short lived Climate Pollutants (SLCPs) include black carbon, methane, hydrofluorocarbons (HFCs) and ground level ozone. Although they have a shorter residence time in the atmosphere than CO2, from a few days to a few decades, they contribute to near term climate change. This POSTnote summarises options for mitigating SLCP concentrations and the benefits and challenges of doing so.

    Phosphate Resources

    World food security is dependent on phosphate fertilisers manufactured from finite deposits of phosphate ore. The majority of remaining reserves are restricted to a limited number of countries raising geopolitical risks. This POSTnote describes the uses of phosphate and summarises ways in which dependence on mineral reserves could be reduced.

    Reducing Emissions from Deforestation

    The UNFCCC REDD+ scheme aims to promote sustainable forest management in developing countries in order to reduce carbon dioxide emissions. Developed countries are expected to provide finance of approximately $20bn per year from 2020. This POSTnote summarises the extent to which REDD+ could contribute to meeting international climate targets, challenges to its implementation and technologies for tracking its performance

    Environmental Citizen Science

    Environmental citizen science traditionally involves members of the public submitting sightings of wildlife to NGOs or records centres, but emerging technologies have recently broadened its use to all kinds of environmental data. This POSTnote summarises different types of citizen science projects, policy-relevant applications and the benefits and challenges of volunteer collected data.

    Smart Metering of Energy and Water

    Smart meters record energy and water usage and improve how this information is relayed to both consumer and suppliers. The Government plans to roll-out smart meters of electricity and gas to all households in Great Britain by the end of 2020. This POSTnote examines the potential benefits and risks associated with smart metering of both water and energy, and the challenges for the energy smart metering roll-out.

    Ancient Woodland

    Ancient woodlands are irreplaceable features of our landscapes that can be high in biodiversity or cultural value. This POSTnote summarises the challenges of conserving the biodiversity and cultural heritage of these sites to provide social and economic benefits, while still meeting the development needs of society.

    Intermittent Electricity Generation

    Sources of electricity that exhibit uncontrolled increases or decreases in output are often referred to as intermittent. This POSTnote examines the effect of wind, solar, wave and tidal intermittency on electricity prices, carbon dioxide emissions and the provision of electricity to meet demand. The note also describes measures to manage intermittency.

    Ambient Air Quality

    National and European regulations have improved UK ambient air quality. However, current air pollution levels continue to harm human health and the environment. This POSTnote summarises the evidence for effects of air pollutants and policies to address them

    New Nuclear Power Technologies

    Nuclear power stations provide a low carbon source of electricity, which could help the UK achieve its policy to reduce greenhouse gas emissions by 80% by 2050. This POSTnote reviews new and potential future nuclear power technologies. It also outlines the regulatory approach toward new nuclear build and summarises some of the related challenges.

    Risks from Climate Feedbacks

    The Fifth Assessment Report of the IPCC concluded that human activities are causing the climate to warm, but there is uncertainty in how the climate will continue to change. Climate feedbacks could both increase and decrease global warming. This POSTnote discusses what climate feedbacks are, as well as the challenges they present for climate change mitigation policies.

    Electricity Demand-Side Response

    Demand-Side Response describes electricity users (the demand side) changing their patterns of use in response to incentives. It is one of several options eligible for Government support introduced by the 2013 Energy Act. This POSTnote outlines DSR, how it is provided, its role for the UK and its potential future development.
