The ONS recently published the UK's environmental accounts for 2011 and they are described as satellite accounts to the main national accounts. They provide information on a wide range of things to do with atmospheric emissions, natural resources such as lands cover, oil and gas reserves, forestry, trade in basic materials, physical flows and monetary accounts related to the industrial, commercial and domestic sectors.
The effects of our activity on the environment have been an important policy issue for the last 40-50 years. There is growing concern about the impact of economic activity on both the global and local environment and also recognition that economic growth and human welfare depend on the enviroment. Raw materials and energy for goods and services, the absorption of waste, basic life support roles and amenities such as landscape are all services provided by the environment.
Environmental accounts provide data on the impact of economic activity on the environment, resource use and the taxes and subsidies associted with them and are sepearated into three dimensions: natural resources, physical flows and monetary. Natural resources accounts include oil and gas reserves, land cover and forestry.
Proven oil reserves at the end of 2009 were 378m tonnes. There has been a transfer of 38m tonnes from probable to proven reserves. Maximum oil reserves (proven, probable and possible) decreased by 19m tonnes to 1,111m tonnes in 2009. There are estimated to be hundreds of millions of tonnes of undiscovered recoverable oil reserves. Oil and gas reserves were worth an estimated value of £182.4bn in 2009, down 1.9% since 2008.
Total land cover in Great Britain is 22.6m hectares. Various types of grassland are the habitats that have increased between 1998 and 2007. Changes have also taken place in woodlands which have increased, arable and horticulture, which have decreased and bracken broad habitat which has also decreased.
The total area covered by woodland was 3.1m hectares or 12.7% of UK land area and is the highest since records began. The woodland area at the end of 2010 is 2.5 times tha area covered in 1924 (when records began). The area of new planting and restocking in 2010-11 was 22,700 hectares. Broadleaved species important for the expansion of the area of native woodland was 82% of new planting but only 27% of restocking.
There was an 8.4% decrease in greenhouse gas emissions in 2009 compared with 2008 bringing the total down by 58.1m tonnes to 636m tonnes of CO2 equivalent.
Material productivity is used to assess progress towards sustainable development by dividing GDP by Domestic Material Consumption (DMC). The environmental accounts show that between 1990 and 2009 material productivity increrased and the trend indicates that material use is falling in relation to economic activity and supports evidence that suggests that economic growth has decoupled from material use since 1990. Some of the environmental impacts associated with consumption may have been transferred abroad because the level of imports has generally risen over that period.

Agriculture's June Survey 2010 Provisional Results
The latest June Survey statistics from Defra show the provisional estimates for land use, crop areas and livestock numbers on agricultural holdings on June 1 2010. They give a good idea of trends but they are provisional and could be subject to amendment at a later date.
The agricultural land area in 2010 was 9.3m hectares. The area on agricultural holdings remained unchanged at 8.9m hectares. Common rough grazing remained unchanged at 428,000 hectares. The arable area also remained more or less unchanged at slightly under 3.8m hectares while to total cropping area increased slightly to 3,915,000 hectares from 3,902,000 hectares in 2009 (revised). All regions increased their wheat area.
The number of cattle increased by 1% to 5.5 million. The total breeding herd was up by 0.9% to 1,916,000. There were 756,000 cattle in the beef herd and 1,160,000 in the dairy breeding herd in 2010.
The number of breeding pigs increased to by 1.4% to 427,000 from 421,000. The number of fattening pigs decreased by 2% to 3.2 million. The female breeding herd numbered 351,000 in 2010 and other breeding pigs increased by 10.7% to 76,000 in 2010 which included 15,000 boars. The total number of pigs decreased by 1.6% to 3,630,000.
The female breeding flock remained unchanged at 6.4 million. The fall in the number of lambs from 7.49 million to 7.24 million was a factor in reducing the total number of sheep to 14.1 million from 14.4 million in 2009.

Farm Land Birds In England
Farmland bird populations declined between 2008 and 2009. The unsmoothed index showed a decline of 5% for England and the smoothed index showed a decline of 3%. Both indices are lower than their lowest recorded value since the 1966 starting value by 53%.
Bird indicators are regarded as being a good indicator of general stat of wildlife because they occupy a wide range of habitats. Twelve of the species included in the index declined between 2008 and 2009 and seven species increased. Many of the species showing a downward trend have been in decline for four or five years. Goldfinch and Jackdaw have shown long-term upward trends.
The indicators of wild bird populations are published by Defra along with the RSPB and the BTO. They show changes in the breeding and wintering populations of common bird species.

Less Agricultural Land Used In Development
The majority of the land use change statistics (LUCS) for land changing to residential use are for 2008. The LUCS have 24 land use categories and 58% of dwellings were built on land previously classed as residential, agricultural, vacant or derelict in 2008. The remaining 42% were built on the remaining 20 land use categories.
In 2008, 12% of dwellings were built on previously agricultural land compared to 14% in 2007, a fall of 2%. There has been a general trend since 1998 to use less agricultural land for new dwellings in favour of previously residential land.
Statistics for changes in the use of previously developed land are for 2007 when an estimated 55% of land changing to developed use was previously developed and 35% was previously agricultural land or agricultural buildings.
Provisional estimates also say that the average density of housing increased from 43 dwellings per hectare in 2008 to 45 dwellings/hectare in 2009. The Green Belt has seen an increase in the percentage of land changing to residential use from 5% in 2007 to 7% in 2008. In 2008, 2% of dwellings were built within the Green Belt which is unchanged since 2004.

More Green Belt Statistics UK
The latest Green belt statistics from the DCLG tell us that on 31 March 2010 there was an estimated 1,639,560 hectares of designated Green Belt land in England. This amounts to about 13% of the total land area of England. The designated Green Belt area of England in March 2009 has been revised and the estimation is now 1,639,650 hectares which amounts to an increase of 810 hectares on the estimate published by DCLG in April 2009. The difference is due to the correcting, improving of measurements of local authorities using digitised data from geographical information systems as opposed to paper maps and Positional Accuracy improvements by the Ordnance Survey. The Comprehensive Spending Review resulted in Departmental Strategic Objectives on Planning which relate to net change in the national area of Green Belt land. The indicator used for this is sustaining the level of Green Belt nationally measured regionally. There has been a net real decreas decrease of 80 hectares between April 2009 and March 2010. The difference is due to new plans being adopted in South Cambridgeshire (70 hectares) and the Mole Valley (10 hectares).
Green Belt policy comprises five purposes for including land in designated Green Belt areas. They are to check urban sprawl, to prevent the merging of neighbouring towns, the safeguard the countryside from encroachment, the preservation of the setting and character of historic towns and to help urban regeneration by encouraging the recycling of derelict and other urban land. Green Belt land once identified can then provide the urban population with opportunities of access to the open countryside and outdoor sport and leisure, the retention and enhancement of landscapes near inhabited areas, improvement of damaged and derelict land, nature conservation and the retaining of land in agricultural, forestry and other related uses.

Supply And Demand Combine To Increase Farm Prices
Farmland prices increased in H2 2009 after a slight fall in H1. The changes were due to a decrease in supply in both commercial and residential farmland sectors, stable demand in the residential sector and increased demand in the commercial sector according the the RICS Rural Land Market Survey for H2 2009. Price expectations increased but more so in commercial.
RICS publishes two different measures of farmland prices, the opinion based and the transaction based measures. The RICS opinion based measure of farmland prices increased by 4% to £12,715/hectare in H2 from £12,172/hectare in H1 2009. Arable land increased by 5% to £13,713/hectare in H2 from £13,085. Pasture land increased by 4%. In H1 it was £11,260/hectare and in H2 it increased in £11,718. The transaction based measure increased by 7.5% in H2 from £15,199 to £16,381/hectare.
Demand for farmland in the residential sector stabilised during H2 2009. Demand for commercial farmland increased. Some surveyors suggest commercial farmers are still interested in expanding their operations. Surveyors also suggest that low interest rates are making commercial farmland more attractive to non-commercial buyers. Supply however is falling in both residential and commercial farmland sectors. These conditions are expected to continue which will help increase prices further during 2010.

Final June Agricultural Survey Results, England 2009
The final June Survey results for England were released by DEFRA and ONS on 19 November 2009. Some of the key results were that the total area of agricultural holdings in England has increased to 9.4m hectares since 2008. The total croppable area is estimated at 4.9m hectares. The area cropped has fallen to 3.99m hectares but the total land out of arable production stands at 231,000 hectares. Fruit and vegetables grown outdoors account for 140,000 hectares, up 2% on 2008. Common rough grazing stands at 427,900 ha. The total agricultural area has increased in size again this year to 9.8m ha.
Owner occupied land is largely the same as 2008 at 6.3m ha. Land rented for more than a year is also unchanged at 3.3m ha. The area under Full Agricultural Tenancy agreements (FAT) continued to decrease, by 2.9%, to 1,680,900 ha and Farm Business Tenancies have increased 3.8% to 1,094,400 ha. Other agreements have risen to 497,800 ha, up 2.2%.
The national herd of cattle remained at around 5.5m according to the Cattle Tracing Scheme. There were 3.9m pigs, up 0.5%. These included 444,000 breeding pigs. The national sheep flock was 14,984,000 sheep and lambs, down 3.5% on June 2008. The female breeding flock of 6,672,000, down 5.1% on last year, included 5,550,000 ewes for further breeding and 797,00 first time breeding ewes. 326,000 ewes were intended for slaughter. Rams totalled 171,000, down 5.4% on 2008.
The total number of people employed in agricultural was 363,000 up nearly 3,000 from last year. These included 223,000 farmers, business partners, directors and spouses of which 127,200 were part-time, 11,900 salaried managers and 127,800 other workers, 49,400 of which were full-time, the rest part-time or seasonal/casual or gang workers.
