For year 1995 and 1985 maps, the land pixels of both the regions were filled with that of 2005. Reh, bhur, usar, and khola tracts of Uttar Pradesh, Punjab and Haryana as well as in several other parts of the country were used for agriculture in the past but had to be abandoned due to some deficiencies in the soil resulting from faulty agricultural practices. The soils in class I need only ordinary crop management practices to maintain their productivity such as fertilization, liming, etc. Soils of this group have gentle slopes and are subject to moderate erosion. This will require massive tree plantations and vigorous restrictions on the reckless felling of trees. The land is nearly level and subject only to slight erosion by wind or water, if properly managed.
The distribution of the current fallow on the other hand presents a slightly different picture. The states were also finding it difficult to present comparable data according to this classification owing to the lack of uniformity in the definitions and scope of classification covered by these five broad categories. Development of Decadal 1985—1995—2005 Land Use and Land Cover Database for India. Classification of Land: In India the classification of land has had its roots in agricultural statistics. It can be assumed that the mapping and Kappa accuracies of the 1995 and 1985 maps are similar to that of 2005 Roy et al.
It is clear that the percentage of area sown more than once is rather low in India as a whole. After some time along with the improvement trusts, municipalities were also established. Also, these soils are inherently low in fertility. Madhya Pradesh has the largest net sown area of 19. So too, pastureland is declining as a result of pressure from agriculture. In some cases, village papers are not maintained; but the estimates of the area under different classes of land are based on the sample survey or other methods to complete the coverage. The Southern Western Ghats: A Biodiversity Conservation Plan.
The study has been executed with a participation of network support from countries like China, Sri Lanka, Myanmar, Thailand, Bhutan, Nepal and Bangladesh. In: Studying the Human Dimensions of Global Environmental Change, Diekmann, A. The errors and discrepancies were corrected using the ground truth data and ancillary information supplemented by existing maps Roy et al. Field surveys and other information existing land and revenue records were used in 5% of the noted change areas to ascertain the nature of change, and the extent and direction of change. The states with substantial proportions of areas under the culturable wastelands are Rajasthan, Odisha and the Union Territory of Goa, Daman and Diu. The importance of planning development is gaining attention as more and more people are exploring the ways for a better quality of life. There has been a rise in the area that is double- cropped and multiple-cropped.
Land provides the base for three fourth of our food, all our timber and all our natural fibres. The pasture land was non-existent on ground, may be due to conversion of such areas to agriculture over a period of time. The soils are deep, productive and easily worked and nearly level. I just downloaded for my cousin. The soils in a capability unit are sufficiently uniform to: i Produce similar kinds of cultivated crops and pasture with similar management practices; ii Require similar conservation treatment and management under the same kind and condition of vegetative cover; and iii Have comparable potential productivity. During the last forty years 1970-71 to 2008-09 the net sown area has remained, by and large, constant at 141 million ha.
The process was applied to the 1985 imagery using the 1995 map as the starting reference. Lands under Casurina trees, thatching grasses, bamboo bushes and other groves for fuel, etc. The future of the Brazilian Amazon. The development of a land cover change model for Southern Senegal. Since the workload in the project was enormous, all the State Remote Sensing Centres and some central organizations were involved in the mapping task. Consists of seasonal needle leaf tree communities with an annual cycle of leaf-on and leaf-off periods.
They prepared both theoretical or sector plans and spatial plans for various uses. They are steep and shallow and more prone to erosion than class V soils. The classification devised for Indian conditions draws heavily from the classificatory approach followed by the United States Department of Agriculture. This is done so as to avoid conflict in activities and to reduce the negative impacts of different activities. Internal changes includes shifting cultivation areas, selective logging due to human pressure on forest resources and habitat loss of wildlife due to reduction in the forests. Land lying fallow for more than one agricultural year but less than five agricultural years has decreased during the recent years.
The amount of this land has been variable right from 1950-51 to 1999-2000, the data for which are available. This increase in forest cover just means an increase within the demarcated area for forests. As per the land use statistics 2013-14, the total geographical area of the country is 328. Fallow land is left uncultivated from 1 to 5 years to help soil recoup its fertility in the natural way depending upon the nature of soil and the nature of fanning. Still their proportions continue to remain substantial in the states of Rajasthan, Bihar, Tamil Nadu, Maharashtra, Andhra Pradesh, Karnataka, West Bengal and the Union Territory of Delhi. However, they are subject to variations of fertility and puddle erosion.
Soil conservation measures in relation of land capability classification: The system of land classification based upon the soil and site characteristics enables one to plan and match soil conservation measures according to the intensity and nature of the problem. Proximate causes and underlying driving forces of tropical deforestation. A further deterioration of existing conditions can, on the other hand, shift the capability to poorer classes. These soils are steep, eroded, shallow or swampy and are completely unsuitable for cultivation. The considerable variation in the area underscores the need to prepare a reliable database using the latest techniques of satellite remote sensing and geomatics. Fallow lands : This category includes all that land which was used for cultivation but is temporarily out of cultivation.
