99-786: 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 (and until 2013 also Wales). Based in Bristol , the Environment Agency is responsible for flood management, waste management , regulating land and water pollution, and conservation. The Environment Agency's stated purpose is, "to protect or enhance

198-539: A licence authority. The agency is funded in part from the UK government Department for Environment, Food and Rural Affairs (DEFRA). Additional money is raised from the issuing of licences and permits such as abstraction licences, waste handler registrations, navigation rights and rod (fishing) licences. Funding for asset management and improvement and acquisition of flood risk management assets has traditionally come from local authorities via flood defence committees. This

297-674: A non-ministerial government department being at a remove from both ministers and any elected assembly or parliament. Typically an NDPB would be established under statute and be accountable to Parliament rather than to His Majesty's Government . This arrangement allows more financial independence since the government is obliged to provide funding to meet statutory obligations. NDPBs are sometimes referred to as quangos . However, this term originally referred to quasi-NGOs bodies that are, at least ostensibly, non-government organisations , but nonetheless perform governmental functions. The backronym "quasi-autonomous national government organization"

396-452: A basic drinking water service in 2017. Of those, 159 million people worldwide drink water directly from surface water sources, such as lakes and streams. One in eight people in the world do not have access to safe water. The world's supply of groundwater is steadily decreasing. Groundwater depletion (or overdrafting ) is occurring for example in Asia, South America and North America. It

495-426: A dynamic interface between surface water and groundwater from aquifers, exchanging flow between rivers and aquifers that may be fully charged or depleted. This is especially significant in karst areas where pot-holes and underground rivers are common. There are several artificial sources of fresh water. One is treated wastewater ( reclaimed water ). Another is atmospheric water generators . Desalinated seawater

594-400: A fifth category: NHS bodies . These bodies consist of boards which advise ministers on particular policy areas. They are often supported by a small secretariat from the parent department, and any expenditure is paid for by that department. These bodies usually deliver a particular public service and are overseen by a board rather than ministers. Appointments are made by ministers following

693-556: A high standard and based on sound science. The agency is the regulatory authority for all waste management activities including the licensing of sites such as landfill , incineration and recycling facilities. It also regulates the movement of hazardous wastes such as fibrous asbestos , infectious clinical wastes and harmful chemicals. The agency issues environmental permits to waste management sites and any individuals or companies found to have caused pollution or have infringed their licence conditions can be prosecuted. In serious cases

792-654: A holistic way of managing water resources began already in the 1950s leading up to the 1977 United Nations Water Conference. The development of IWRM was particularly recommended in the final statement of the ministers at the International Conference on Water and the Environment in 1992, known as the Dublin Statement . This concept aims to promote changes in practices which are considered fundamental to improved water resource management . IWRM

891-527: A report by consultants in 2001, these are estimated to prevent annual average damage costs of approximately £3.5 billion. The agency also invests in improving or providing new installations in areas where there remains a high risk of flooding, particularly where, because of the possible consequences, the damage risk is the highest. The Thames Barrier was completed long before the EA was created but more recent examples of major defences against coastal flooding include

990-419: A small discharge to each plant. Micro-irrigation uses less pressure and water flow than sprinkler irrigation. Drip irrigation delivers water directly to the root zone of plants. Subirrigation has been used in field crops in areas with high water tables for many years. It involves artificially raising the water table to moisten the soil below the root zone of plants. It is estimated that 22% of worldwide water

1089-456: A source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water ( wastewater ) or desalinated water ( seawater ). 97% of the water on Earth is salt water and only three percent is fresh water ; slightly over two-thirds of this is frozen in glaciers and polar ice caps . The remaining unfrozen freshwater

SECTION 10

1188-450: Is pollution . Pollution includes discharged solutes and increased water temperature ( thermal pollution ). It is estimated that 8% of worldwide water use is for domestic purposes. These include drinking water , bathing , cooking , toilet flushing , cleaning, laundry and gardening . Basic domestic water requirements have been estimated by Peter Gleick at around 50 liters per person per day, excluding water for gardens. Drinking water

1287-403: Is a comprehensive, participatory planning and implementation tool for managing and developing water resources in a way that balances social and economic needs, and that ensures the protection of ecosystems for future generations. In addition, in light of contributing the achievement of Sustainable Development goals (SDGs) , IWRM has been evolving into more sustainable approach as it considers

1386-420: Is a long-established practice. This is especially so in arid countries. Reusing wastewater as part of sustainable water management allows water to remain an alternative water source for human activities. This can reduce scarcity . It also eases pressures on groundwater and other natural water bodies. Desalination is a process that removes mineral components from saline water . More generally, desalination

1485-441: Is also employed to protect crops from frost , suppress weed growth in grain fields, and prevent soil consolidation . It is also used to cool livestock , reduce dust , dispose of sewage , and support mining operations. Drainage , which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water

1584-413: Is also known as groundwater recharge . Reused water also serve various needs in residences such as toilet flushing , businesses, and industry. It is possible to treat wastewater to reach drinking water standards. Injecting reclaimed water into the water supply distribution system is known as direct potable reuse. Drinking reclaimed water is not typical. Reusing treated municipal wastewater for irrigation

1683-399: Is also responsible for increasing public awareness of flood risk, flood forecasting and warning and has a general supervisory duty for flood risk management. As of 2008 the Environment Agency also has a strategic overview role for all flood and coastal erosion risk management. The term "Flood Risk Management" in place of "Flood Defence" recognises that managed flooding is essential to meet

1782-520: Is an important consideration. Some human water users have an intermittent need for water. For example, many farms require large quantities of water in the spring, and no water at all in the winter. Other users have a continuous need for water, such as a power plant that requires water for cooling. Over the long term the average rate of precipitation within a watershed is the upper bound for average consumption of natural surface water from that watershed. Irrigation (also referred to as watering of plants)

1881-728: Is another important source. It is important to consider the economic and environmental side effects of these technologies. Water reclamation is the process of converting municipal wastewater or sewage and industrial wastewater into water that can be reused for a variety of purposes . It is also called wastewater reuse, water reuse or water recycling. There are many types of reuse. It is possible to reuse water in this way in cities or for irrigation in agriculture. Other types of reuse are environmental reuse, industrial reuse, and reuse for drinking water, whether planned or not. Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater . This latter

1980-692: Is around £22& per annum. The agency uses the registration fees of some 31,000 craft on the waterways to provide some of the income. The agency's responsibilities include the non-tidal River Thames , the Medway Navigation , River Wye and River Lugg , the Royal Military Canal and the Fens and Anglian systems . The Environment Agency is organising the Fens Waterways Link a major construction project to link rivers in

2079-446: Is called the water table . Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps , and can form oases or wetlands . Groundwater is also often withdrawn for agricultural , municipal , and industrial use by constructing and operating extraction wells . The study of the distribution and movement of groundwater is hydrogeology , also called groundwater hydrology . Throughout

SECTION 20

2178-491: Is carried out in line with the National Planning Policy Framework . The agency provides technical advice on the flood risk assessment that must be submitted with most planning applications in flood risk areas. The agency also runs public awareness campaigns to inform those at risk who may be unaware that they live in an area that is prone to flooding, as well as providing information about what

2277-469: Is ever-increasing demand for drinking , manufacturing , leisure and agriculture . Due to the small percentage of water available, optimizing the fresh water we have left from natural resources has been a growing challenge around the world. Much effort in water resource management is directed at optimizing the use of water and in minimizing the environmental impact of water use on the natural environment. The observation of water as an integral part of

2376-447: Is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water , under river flow, groundwater and frozen water . People use water resources for agricultural , industrial and household activities. Water resources are under threat from multiple issues. There is water scarcity , water pollution , water conflict and climate change . Fresh water

2475-414: Is in principle a renewable resource . However, the world's supply of groundwater is steadily decreasing. Groundwater depletion (or overdrafting ) is occurring for example in Asia, South America and North America. Natural sources of fresh water include surface water , under river flow, groundwater and frozen water . Surface water is water in a river, lake or fresh water wetland . Surface water

2574-609: Is low, and use the stored water to produce electricity when demand is high. Thermoelectric power plants using cooling towers have high consumption, nearly equal to their withdrawal, as most of the withdrawn water is evaporated as part of the cooling process. The withdrawal, however, is lower than in once-through cooling systems. Water is also used in many large scale industrial processes, such as thermoelectric power production, oil refining, fertilizer production and other chemical plant use, and natural gas extraction from shale rock . Discharge of untreated water from industrial uses

2673-442: Is naturally replenished by precipitation and naturally lost through discharge to the oceans , evaporation , evapotranspiration and groundwater recharge . The only natural input to any surface water system is precipitation within its watershed . The total quantity of water in that system at any given time is also dependent on many other factors. These factors include storage capacity in lakes, wetlands and artificial reservoirs ,

2772-477: Is no limit on the amount of the fine and sentences of up to five years imprisonment may be imposed on those responsible for the pollution or on the directors of companies causing pollution. The agency has an important role in conservation and ecology specifically along rivers and in wetlands. More general responsibility for the countryside and natural environment in England falls to the organisation Natural England . The Environment Agency's activities support users of

2871-576: Is one of the few water resources independent of rainfall. Researchers proposed air capture over oceans which would "significantly increasing freshwater through the capture of humid air over oceans" to address present and, especially, future water scarcity/insecurity. A 2021 study proposed hypothetical portable solar-powered atmospheric water harvesting devices . However, such off-the-grid generation may sometimes "undermine efforts to develop permanent piped infrastructure " among other problems. The total quantity of water available at any given time

2970-434: Is required by law under the provisions of a number of European Directives to be reported both to Parliament and to be made public. Some of these duties have been in force through predecessor agencies and as a consequence the agency maintains some long term data sets which in some cases such as the harmonised monitoring scheme exceed 30 years of consistent data collection. Monitoring is also carried out of many discharges to

3069-423: Is still unclear how much natural renewal balances this usage, and whether ecosystems are threatened. Water resource management is the activity of planning, developing, distributing and managing the optimum use of water resources. It is an aspect of water cycle management . The field of water resources management will have to continue to adapt to the current and future issues facing the allocation of water. With

3168-419: Is supplied to plants. Surface irrigation , also known as gravity irrigation, is the oldest form of irrigation and has been in use for thousands of years. In sprinkler irrigation , water is piped to one or more central locations within the field and distributed by overhead high-pressure water devices. Micro-irrigation is a system that distributes water under low pressure through a piped network and applies it as

3267-432: Is the practice of applying controlled amounts of water to land to help grow crops , landscape plants , and lawns . Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation

3366-499: Is the removal of salts and minerals from a substance. One example is soil desalination . This is important for agriculture. It is possible to desalinate saltwater, especially sea water , to produce water for human consumption or irrigation. The by-product of the desalination process is brine . Many seagoing ships and submarines use desalination. Modern interest in desalination mostly focuses on cost-effective provision of fresh water for human use. Along with recycled wastewater , it

3465-443: Is to establish an inner, urban, water cycle loop through the implementation of reuse strategies. Developing this urban water cycle loop requires an understanding both of the natural, pre-development, water balance and the post-development water balance. Accounting for flows in the pre- and post-development systems is an important step toward limiting urban impacts on the natural water cycle. Water resource management and governance

3564-481: Is used in industry . Major industrial users include hydroelectric dams, thermoelectric power plants , which use water for cooling , ore and oil refineries , which use water in chemical processes , and manufacturing plants, which use water as a solvent . Water withdrawal can be very high for certain industries, but consumption is generally much lower than that of agriculture. Water is used in renewable power generation. Hydroelectric power derives energy from

3663-516: Is used in this usage which is normally pejorative. In March 2009 there were nearly 800 public bodies that were sponsored by the UK Government. This total included 198 executive NDPBs, 410 advisory bodies, 33 tribunals, 21 public corporations, the Bank of England , 2 public broadcasting authorities and 23 NHS bodies. However, the classification is conservative and does not include bodies that are

3762-423: Is used to fund vital work to improve and protect fish and fisheries. Income generated is invested directly back into the angling community, improving fish stocks, boosting opportunities for anglers as well as undertaking fisheries enforcement, habitat improvement and fish rescues when needed. It is not used to fund wider water quality investigations or enforcement action. This is funded directly by government. After

3861-417: Is water that is of sufficiently high quality so that it can be consumed or used without risk of immediate or long term harm. Such water is commonly called potable water. In most developed countries, the water supplied to domestic, commerce and industry is all of drinking water standard even though only a very small proportion is actually consumed or used in food preparation. 844 million people still lacked even

3960-572: The Canal & River Trust , the Environment Agency is the second largest navigation authority in the United Kingdom managing navigation for 634 miles (1,020 km) of England's rivers. The Agency's lock-keepers maintain and operate systems of sluices , weirs and locks to manage water-levels for navigation, and where necessary to control flooding. Annual spending to maintain these installations, with an estimated replacement value of £700M,

4059-644: The Conservatives' complacency in power in the 1990s, presented much material interpreted as evidence of questionable government practices. This concern led to the formation of a Committee on Standards in Public Life (the Nolan Committee) which first reported in 1995 and recommended the creation of a "public appointments commissioner" to make sure that appropriate standards were met in the appointment of members of NDPBs. The Government accepted

The Environment Agency provides flood forecasting and warning systems and maintains maps of areas liable to flood, as well as preparing emergency plans and responding when an event occurs. The Environment Agency carries out an advisory function in development control – commenting on planning applications within flood risk areas, providing advice to assist planning authorities in ensuring that any development

4356-599: The River Dee in England and EA staff exercise operational responsibility for those parts of the River Severn catchment in Wales. The Environment Agency employs around 10,600 staff. It is organised into eight directorates that report to the chief executive. There are two "policy and process" directorates. One deals with Flood and Coastal Risk Management and the other with Environment and Business. These are backed up by

4455-613: The River Restoration Centre at Cranfield University . Until the formation of the Environment Agency, the Government took specialist advice on the management of the environment from civil servants employed in appropriate ministries. This led to considerable duplication of effort and frequent disagreements between Government and the regulatory agencies. The Environment Agency now advises Government directly about those issues within its purview. The operational arm of

Complex arrangements exist for the management of river regulation reservoirs , which are used to store winter water in the wetter parts of England to maintain levels in the summer time so that there is sufficient water to supply the drier parts of

4653-457: The Severn bore . The EA operates a variety of equipment and machinery along with a transport fleet in order to carry out the specialised duties of its officers, namely in survey, incident response and monitoring. Due to the remit of the EA, this includes land vehicles, marine vessels and light aircraft. The agency uses its influence and provides education to change attitudes and behaviour towards

4752-607: The ecosystem is based on integrated water resources management , based on the 1992 Dublin Principles (see below). Sustainable water management requires a holistic approach based on the principles of Integrated Water Resource Management , originally articulated in 1992 at the Dublin (January) and Rio (July) conferences. The four Dublin Principles, promulgated in the Dublin Statement are: Implementation of these principles has guided reform of national water management law around

5148-484: The Environment Agency consists of 14 areas, all of which report to the Director of Operations. As of April 2014, the Environment Agency removed its regional level of administration (formerly Anglian Region, Midlands Region, North West Region, South East Region, South West Region and Yorkshire & North East Region) to be replaced by an "area once, national once" model. The 14 area names were also changed to better reflect

5247-409: The Environment Agency has the power to revoke the environmental permits issued to sites that contravene the conditions of their permits stopping all waste handling activities. The agency has a duty to maintain and improve the quality of surface waters and ground-waters and, as part of the duty, it monitors the quality of rivers, lakes, the sea and groundwater on a regular basis. Much of this information

5346-642: The European, national and local level. Local authorities regulate air pollution from smaller industrial processes. The agency works with local authorities, National Highways and others to implement the UK government's air quality strategy in England as mandated in the Environment Act 1995 . The Environment Agency has an Air Quality Modelling and Assessment Unit (AQMAU) that aims to ensure that air quality assessments for permit applications, enforcement and air pollution incident investigations are consistent, of

The Environment Agency is the harbour authority for Rye and the conservancy authority for the Dee Estuary . The Environment Agency has also published information about tidal bores , these being the Trent Aegir and

5643-556: The Ministry of Justice. These bodies were formerly known as "boards of visitors" and are responsible for the state of prisons, their administration, and the treatment of prisoners. The Home Office is responsible for their costs and has to note all expenses. NDPB differ from executive agencies as they are not created to carry out ministerial orders or policy, instead they are more or less self-determining and enjoy greater independence. They are also not directly part of government like

5742-491: The Nexus approach, which is a cross-sectoral water resource management. The Nexus approach is based on the recognition that "water, energy and food are closely linked through global and local water, carbon and energy cycles or chains." An IWRM approach aims at avoiding a fragmented approach of water resources management by considering the following aspects: Enabling environment, roles of Institutions, management Instruments. Some of

5841-716: The UK's Conservative-Liberal coalition published a review of NDPBs recommending closure or merger of nearly two hundred bodies, and the transfer of others to the private sector. This process was colloquially termed the "bonfire of the quangos". NDPBs are classified under code S.13112 of the European System of Accounts (ESA.95). However, Statistics UK does not break out the detail for these bodies and they are consolidated into General Government (S.1311).

Of the remainder, 12% goes to water resources , and 6% to other water functions including navigation and wildlife. The Secretary of State for Environment, Food and Rural Affairs has the lead sponsorship responsibility for

6237-417: The aquatic environment including sewage effluents and trade and agricultural discharges. The agency manages the use and conservation of water through the issue of water abstraction licences for activities such as drinking water supply, artificial irrigation and hydro-electricity generation. The agency is in charge of inland rivers, estuaries and harbours in England. Its remit also extends into Scotland in

As with other resource management , this is rarely possible in practice so decision-makers must prioritise issues of sustainability, equity and factor optimisation (in that order!) to achieve acceptable outcomes. One of the biggest concerns for water-based resources in the future is

6633-638: The country with drinking water. The Environment Agency fisheries service has a statutory duty to maintain, improve and develop migratory and freshwater fisheries as set out in the Environment Act 1995. The interpretation of this is set out in Ministerial guidance as: The Environment Agency has the power under the Salmon and Freshwater Fisheries Act 1975 to license fishing for salmon trout, freshwater fish, eels, lamprey and smelt and to set duties for

For many rivers in large valleys, this unseen component of flow may greatly exceed the visible flow. The hyporheic zone often forms

6831-440: The cross-cutting conditions that are also important to consider when implementing IWRM are: Political will and commitment, capacity development, adequate investment, financial stability and sustainable cost recovery, monitoring and evaluation. There is not one correct administrative model. The art of IWRM lies in selecting, adjusting and applying the right mix of these tools for a given situation. IWRM practices depend on context; at

6930-431: The environment are commented on in any detail. For many years the agency has been offering strong advice against the development of land in floodplains because of the risk of flooding. Whilst in some instances, this advice may not have been appreciated in its entirety, in a large number of cases this advice has been used to reach decisions on planning applications. The Environment Agency is also an advisory board member of

Floodline covers England, Wales and Scotland but not Northern Ireland, and provides information and advice including property flood-risk checks, flood warnings, and flood preparation advice. In partnership with the Met Office it runs

7425-583: The force of water flowing downhill, driving a turbine connected to a generator. This hydroelectricity is a low-cost, non-polluting, renewable energy source. Significantly, hydroelectric power can also be used for load following unlike most renewable energy sources which are intermittent . Ultimately, the energy in a hydroelectric power plant is supplied by the sun. Heat from the sun evaporates water, which condenses as rain in higher altitudes and flows downhill. Pumped-storage hydroelectric plants also exist, which use grid electricity to pump water uphill when demand

To complicate matters, temperatures there are rising more rapidly than the global average. In Nepal, the temperature has risen by 0.6 degrees Celsius over the last decade, whereas globally, the Earth has warmed approximately 0.7 degrees Celsius over

7623-489: The growing uncertainties of global climate change and the long-term impacts of past management actions, this decision-making will be even more difficult. It is likely that ongoing climate change will lead to situations that have not been encountered. As a result, alternative management strategies, including participatory approaches and adaptive capacity are increasingly being used to strengthen water decision-making. Ideally, water resource management planning has regard to all

7722-442: The implementation of IWRM at a global level. The third World Water Forum recommended IWRM and discussed information sharing, stakeholder participation, and gender and class dynamics. Operationally, IWRM approaches involve applying knowledge from various disciplines as well as the insights from diverse stakeholders to devise and implement efficient, equitable and sustainable solutions to water and development problems. As such, IWRM

All of these factors also affect the proportions of water loss. Humans often increase storage capacity by constructing reservoirs and decrease it by draining wetlands. Humans often increase runoff quantities and velocities by paving areas and channelizing

8118-634: The predecessor bodies were disbanded and the local authorities relinquished their waste regulatory role. At the same time, the agency took responsibility for issuing flood warnings to the public, a role previously held by the police. In 2010 a new national headquarters for the agency was opened at Horizon House in Deanery Road, Bristol . The building, which was designed by Alec French Architects, received Building Research Establishment Environmental Assessment ( BREEAM ) certification for its environmentally friendly construction and operation which includes

8217-502: The provision of fishing licences. Fishing licence income along with a small amount of Grant in Aid (GiA) provides the funding to deliver the statutory duty to maintain, improve and develop freshwater and migratory fisheries, including the current fisheries service provided to recreational anglers. The EA's funding principles mean that income from the sale of fishing licences is entirely ringfenced re-invested back into fisheries work. Many of

8316-686: The recommendation, and the Office of the Commissioner for Public Appointments was established in November 1995. While in opposition, the Labour Party promised to reduce the number and power of NDPBs. The use of NDPBs continued under the Labour government in office from 1997 to 2010, though the political controversy associated with NDPBs in the mid-1990s for the most part died away. In 2010

8415-436: The requirements of a sustainable flood strategy. It is often not economically feasible or even desirable to prevent all forms of flooding in all locations, and so the Environment Agency uses its powers to reduce either the likelihood or consequences of flooding. The Environment Agency is responsible for operating, maintaining and replacing an estimated £20 billion worth of flood risk management (FRM) installations. According to

8514-546: The responsibility of devolved government , various lower tier boards (including a considerable number within the NHS), and also other boards operating in the public sector (e.g. school governors and police authorities). These appointed bodies performed a large variety of tasks, for example health trusts , or the Welsh Development Agency , and by 1992 were responsible for some 25% of all government expenditure in

8613-506: The resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems ". Some scholars say that IWRM is complementary to water security because water security is a goal or destination, whilst IWRM is the process necessary to achieve that goal. IWRM is a paradigm that emerged at international conferences in the late 1900s and early 2000s, although participatory water management institutions have existed for centuries. Discussions on

8712-558: The rivers and wetlands, including anglers and boaters. The agency states that they take a "leading role in limiting and preparing for the impacts of climate change." The agency is a regulator for the release of air pollutants into the atmosphere from large, complex industrial processes. This will soon include emissions from some large-scale agricultural activities, but air pollutant releases from many agricultural activities will continue to be unregulated. Major sources of air pollution, such as transport, are subject to various measures at

8811-442: The scope of the entire river basin. IUWM is commonly seen as a strategy for achieving the goals of Water Sensitive Urban Design . IUWM seeks to change the impact of urban development on the natural water cycle , based on the premise that by managing the urban water cycle as a whole; a more efficient use of resources can be achieved providing not only economic benefits but also improved social and environmental outcomes. One approach

8910-624: The societal and environmental outcomes the fisheries service currently deliver, and aspire to deliver on a greater scale, is through partnership working. Working with partners such as the Angling Trust, the Wild Trout Trust and the Riverfly partnership allows the EA to maximise fishing licence income through match funding to deliver against key benefits for fishing and fisheries across the country. Income from fishing licence sales

9009-510: The stream flow. Natural surface water can be augmented by importing surface water from another watershed through a canal or pipeline . Brazil is estimated to have the largest supply of fresh water in the world, followed by Russia and Canada . Glacier runoff is considered to be surface water. The Himalayas, which are often called "The Roof of the World", contain some of the most extensive and rough high altitude areas on Earth as well as

9108-670: The three-mile limit which includes 2 million hectares of coastal waters. In a sharing arrangement with the Scottish Environment Protection Agency (SEPA), it also exercises some of its functions over parts of the catchments of the River Tweed and the Border Esk which are, for the most part, in Scotland . Similarly, in an arrangement with NRW , political and operational areas are not coterminus. NRW staff exercise responsibility for parts of

9207-414: The use of sustainable materials, natural ventilation and cooling, photoelectric panels and rainwater harvesting . On 24 April 2013, Horizon House suffered a fire leading to its closure for several weeks. An investigation into the fire found it was that result of workmen accidentally igniting the environmentally friendly cavity wall insulation on the ground floor and due to the design of the upward airflow

9306-568: The whole of England and Wales but with specifically designated border arrangements with Scotland covering the catchment of the River Tweed . It took over the roles and responsibilities of the National Rivers Authority (NRA), Her Majesty's Inspectorate of Pollution (HMIP) and the waste regulation authorities in England and Wales including the London Waste Regulation Authority (LWRA). All of

9405-578: The world since 1992. Further challenges to sustainable and equitable water resources management include the fact that many water bodies are shared across boundaries which may be international (see water conflict ) or intra-national (see Murray-Darling basin ). Integrated water resources management (IWRM) has been defined by the Global Water Partnership (GWP) as "a process which promotes the coordinated development and management of water, land and related resources, in order to maximize

9504-715: Was a topic of the second World Water Forum , which was attended by a more varied group of stakeholders than the preceding conferences and contributed to the creation of the GWP. In the International Water Association definition, IWRM rests upon three principles that together act as the overall framework: In 2002, the development of IWRM was discussed at the World Summit on Sustainable Development held in Johannesburg, which aimed to encourage

9603-545: Was merged into Natural Resources Wales , a separate body managing the Welsh environment and natural resources. The Environment Agency is the principal flood risk management operating authority . It has the power (but not the legal obligation) to manage flood risk from designated main rivers and the sea. These functions in relation to other rivers (defined as ordinary watercourses ) in England are undertaken by local authorities or internal drainage boards . The Environment Agency

9702-404: Was provided in the form of 'flood defence grant-in-aid' from government (£578 million for England and £50 million for Wales). In addition, £347 million (34 per cent) was raised through statutory charging schemes and flood defence levies; and a further £50 million (5 per cent) came from other miscellaneous sources. In 2007–08 had an operational budget of £1.025 billion, of which £628m was grant from

9801-474: Was then effectively repaid by central government in later years as part of the Formula Spending Share. In 2005 this was simplified by making a direct transfer from Treasury to the Environment Agency in the form of flood defence grant-in-aid . The Environment Agency's total funding in 2007–08 was £1,025 million, an increase of £23 million on 2006–07. Of that total, £629 million (61 per cent)
