New Zealand is divided into sixteen regions for local government purposes. Eleven are administered by regional councils, and five are administered by unitary authorities, which are territorial authorities that also perform the functions of regional councils. The Chatham Islands Council is not a region but is similar to a unitary authority, authorised under its own legislation.
A site of special scientific interest (SSSI) in Great Britain, or an area of special scientific interest (ASSI) in the Isle of Man and Northern Ireland, is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I".
Stormwater, also written storm water, is water that originates from precipitation (storm), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil (infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff. Most runoff is conveyed directly as surface water to nearby streams, rivers or other large water bodies without treatment.
The Department for Environment, Food and Rural Affairs (Defra) is a department of His Majesty's Government in the United Kingdom responsible for environmental protection, food production and standards, agriculture, fisheries and rural communities in the entire United Kingdom. Concordats set out agreed frameworks for co operation, between it and the Scottish Government, Welsh Government and Northern Ireland Executive, which have devolved responsibilities for these matters in their respective nations.
The Environment Agency (EA) is a non-departmental public body, established in 1996 and sponsored by the United Kingdom government's Department for Environment, Food and Rural Affairs, with responsibilities relating to the protection and enhancement of the environment in England.
The Scottish Environment Protection Agency is Scotland's environmental regulator and national flood forecasting, flood warning and strategic flood risk management authority. Its main role is to protect and improve Scotland's environment. SEPA does this by helping business and industry to understand their environmental responsibilities, enabling customers to comply with legislation and good practice and to realise the economic benefits of good environmental practice. One of the ways SEPA does this is through the NetRegs environmental guidance service. It protects communities by regulating activities that can cause harmful pollution and by monitoring the quality of Scotland's air, land and water. The regulations it implements also cover the storage, transport and disposal of radioactive materials.
The Water Act 1973 is an Act of the Parliament of the United Kingdom that reorganised the water, sewage and river management industry in England and Wales. Water supply and sewage disposal were removed from local authority control, and ten larger regional water authorities were set up, under state control based on the areas of super-sets of river authorities which were also subsumed into the new authorities. Each regional water authority consisted of members appointed by the Secretary of State for the Environment, and by the various local authorities in its area.
A water board is a regional or national organisation that has very different functions from one country to another. The functions range from flood control and water resources management at the regional or local level, water charging and financing at the river basin level (France), bulk water supply, regulation of pricing and service quality of drinking water supply at the national level (Kenya) or the coordination of water resources policies between various Ministries and agencies at the national level together with the regulation of drinking water supply.
A flood risk assessment (FRA) is an assessment of the risk of flooding from all flooding mechanisms, the identification of flood mitigation measures and should provide advice on actions to be taken before and during a flood.
An internal drainage board (IDB) is a type of operating authority which is established in areas of special drainage need in England and Wales with permissive powers to undertake work to secure clean water drainage and water level management within drainage districts. The area of an IDB is not determined by county or metropolitan council boundaries, but by water catchment areas within a given region. IDBs are geographically concentrated in the Broads, Fens in East Anglia and Lincolnshire, Somerset Levels and Yorkshire.
The Association of Drainage Authorities (ADA) is a membership body for internal drainage boards and other stakeholders in water level management in the United Kingdom.
An ordinary watercourse is one of the two types of watercourse in statutory language in England and Wales.
Public water supply and sanitation in England and Wales has been characterised by universal access and generally good service quality. In both England and Wales, water companies became privatised in 1989, although Dwr Cymru operates as a not-for-profit organisation. Whilst independent assessments place the cost of water provision in Wales and England as higher than most major countries in the EU between 1989 and 2005, the government body responsible for water regulation, together with the water companies, have claimed improvements in service quality during that period.
Flood control methods are used to reduce or prevent the detrimental effects of flood waters. Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. A distinction is made between structural and non-structural flood control measures. Structural methods physically restrain the flood waters, whereas non-structural methods do not. Building hard infrastructure to prevent flooding, such as flood walls, is effective at managing flooding. However, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. To prevent or manage coastal flooding, coastal management practices have to handle natural processes like tides but also the human cased sea level rise.
Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation. Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides. Slow-onset hazards, such as erosion and gradual inundation, develop incrementally over extended periods.
The 2013–2014 United Kingdom winter floods saw areas of Ireland and the United Kingdom inundated following severe storms. The south of England saw heavy rainfalls associated with these storms which caused widespread flooding, power cuts and major disruptions to transport. Economically, the worst affected areas were Somerset, Devon, Dorset and Cornwall in the south west and the Thames Valley in the south east.
The Salmon and Freshwater Fisheries Act 1975 is a law passed by the government of the United Kingdom in an attempt to protect salmon and trout from commercial poaching, to protect migration routes, to prevent willful vandalism and neglect of fisheries, ensure correct licensing and water authority approval. This helps to sustain the rural inland freshwater fisheries industry, which employs around 37,000 people in the UK.
The Water Act 1989 is an Act of the Parliament of the United Kingdom that reorganised the bodies responsible for all aspects of water within England and Wales. Whereas previous legislation, particularly the Water Act 1973, had focused on providing a single unifying body with responsibility for all water-related functions within a river basin or series of river basins, this legislation divided those functions up again, with water supply, sewerage and sewage disposal being controlled by private companies, and the river management, land drainage and pollution functions becoming the responsibility of the National Rivers Authority.
Colin Reginald Thorne is Chair of Physical Geography at the University of Nottingham. A fluvial geomorphologist with an educational background in environmental sciences, civil engineering and physical geography; he has published 9 books and over 120 journal papers and book chapters.
The Environment (Wales) Act 2016 is an Act of the National Assembly for Wales that was given royal assent on 21 March 2016. It put into place the necessary legislation to enable the planning and management of the natural resources of Wales in a more sustainable, pro-active and joined-up way than was previously possible.
