The Impact

The world is undergoing the largest wave of urban growth in history. More than half of the world’s population now lives in towns and cities, and by 2030 this number will swell to about 5 billion. ‘Urbanization has the potential to usher in a new era of wellbeing, resource efficiency and economic growth. But due to increased population the pressure of demand also increases in urban areas’ (Drakakis-Smith, David, 1996). The loss of agricultural land to other land uses occasioned by urban growth is an issue of growing concern worldwide, particularly in the developing countries like India. This paper is an attempt to assess the impact of urbanization on land use and land cover patterns in Ajmer city. Recent trends indicate that the rural urban migration and religious significance of the place attracting thousands of tourists every year, have immensely contributed in the increasing population of city and is causing change in land use patterns. This accelerating urban sprawl has led to shrinking of the agricultural land and land holdings. Due to increased rate of urbanization, the agricultural areas have been transformed into residential and industrial areas (Retnaraj D,1994). There are several key factors which cause increase in population here such as Smart City Projects, potential for employment, higher education, more comfortable and quality housing, better health facilities, high living standard etc. Population pressure not only directly increases the demand for food, but also indirectly reduces its supply through building development, environmental degradation and marginalization of food production (Aldington T, 1997). Also, there are several issues which are associated with continuous increase in population i.e. land degradation, pollution, poverty, slums, unaffordable housing etc. Pollution, formulation of slums, transportation congestion, environmental hazards, land degradation and crime are some of the major impacts of urbanization on Ajmer city. This study involves mapping of land use patterns by analyzing data and satellite imagery taken at different time periods. The satellite images of year 2000 and 2017 are used. The change detection techniques are used with the help of Geographical Information System software like ERDAS and ArcGIS. The supervised classification of all the three satellite images is done by ERDAS software to demarcate and analyze land use change.

Past Land Use

The evaluation of the impacts of land-use change on the water resources has been, many times, limited by the knowledge of past land use conditions. Most publications on this field present only a vague description of the past land use, which is usually insufficient for more comprehensive studies. This study presents the first reconstruction of the historical land use patterns in Amazonia, that includes both croplands and pasturelands, for the period 1940-1995. During this period, Amazonia experienced the fastest rates of land use change in the world, growing 4-fold from 193,269 km2 in 1940 to 724,899 km2 in 1995. This reconstruction is based on a merging of satellite imagery and census data, and provides a 5'x5' yearly dataset of land use in three different categories (cropland, natural pastureland and planted pastureland) for Amazonia. This dataset will be an important step towards understanding the impacts of changes in land use on the water resources in Amazonia.

Degraded Water Quality

The relationships between land use patterns and water quality in trans-boundary watersheds remain elusive due to the heterogeneous natural environment. We assess the impact of land use patterns on water quality at different eco-functional regions in the Songhua River basin during two hydrological seasons in 2016. The partial least square regression indicated that agricultural activities associated with most water quality pollutants in the region with a relative higher runoff depth and lower altitude. Intensive grazing had negative impacts on water quality in plain areas with low runoff depth. Forest was related negatively with degraded water quality in mountainous high flow region. Patch density and edge density had major impacts on water quality contaminants especially in mountainous high flow region; Contagion was related with non-point source pollutants in mountainous normal flow region; landscape shape index was an effective indicator for anions in some eco-regions in high flow season; Shannon’s diversity index contributed to degraded water quality in each eco-region, indicating the variation of landscape heterogeneity influenced water quality regardless of natural environment. The results provide a regional based approach of identifying the impact of land use patterns on water quality in order to improve water pollution control and land use management.

New Jobs

The attraction of new industry is an ongoing concern for most local officials. Generally, local officials are aware of the private sector benefits of new jobs and income. Attention is beginning to be paid to secondary private sector impacts such as the effect of new industry on local wage rates and the problems associated with in-migration of labor to fill new jobs. Borts and Stein (Chapter 9) give a theoretical discussion of these issues.In addition researchers and policy makers are interested in the development of models that estimate the impact of new industry on local government expenditures and revenues. Many computerized versions of local fiscal impact models are reviewed in a recently published text (Burchell and Listokin, pp. 345-59). The popularity of these models is understandable because of the potential benefits to be derived from accurate forecasts of local fiscal impact. For example, a community can determine the magnitude of a tax incentive it can offer to industry and still maintain a positive fiscal impact for local government. Zoning laws can be written to encourage land use patterns that will be efficient from the public sector's perspective if the public expenditures and public revenues associated with alternative land use patterns can be predicted. Finally, local areas may be able to demonstrate to state government that a large-scale industrial project will benefit the fiscal position of the state but be a burden to the local fiscal balance.

<em>Abstract</em>.—Paddlefish <em>Polyodon spathula </em>are large, riverine fishes that occupy extensive home ranges and often migrate long distances in spring to spawn. As a result of these life history characteristics, paddlefish require many habitats to sustain their population over time. Largely as a result of anthropogenic activities, many of the habitats historically used by paddlefish have been altered or destroyed and remaining paddlefish habitats are being threatened by dam construction, channelization and dredging, and altered land use within watersheds. Understanding how habitat alteration may affect paddlefish populations, and identifying threats to current paddlefish habitat, is needed for the management of this species. We review the threats to paddlefish habitats and assess how anthropogenic habitat alterations, such as changes to natural hydrology through the construction of dams and channelization of large rivers or altered land-use patterns leading to increased sedimentation, have affected paddlefish populations. Recent river restoration and conservation measures that help protect and restore paddlefish habitats include fish passage structures and controlled water releases from dams to simulate a more natural hydrograph. New threats such as global climate change may alter paddlefish habitats in the future. Continued efforts to minimize the impact of anthropogenic changes to paddlefish habitats, and measures to restore natural riverine conditions, may help conserve vital habitats for paddlefish populations.

This paper considers the impact of existing land use patterns on housing supply price elasticities in local areas of England, under existing planning policies. The paper demonstrates that, despite common national planning policies, local supply responses to market pressures vary considerably, because of differences in historical land uses. The study area covers the Thames Gateway and Thames Valley, which lie to the east and west of London respectively. However, whereas the latter is one of the wealthiest areas of England, the former includes some of the highest pockets of deprivation and was a government priority area for increasing housing supply. Due to differences in historical land use and geography, the price elasticity in the least constrained area is approximately six times higher than the most constrained.

Past Land Use

This paper analyzes remotely sensed data sources to evaluate land-use history within the Peruvian department of Amazonas and demonstrates the utility of comparing present and past land-use patterns using continuous datasets, as a complement to the often dispersed and discrete data produced by archaeological and paleoecological field studies. We characterize the distribution of ancient (ca. AD 1–1550) terracing based on data drawn from high-resolution satellite imagery and compare it to patterns of deforestation between 2001 and 2019, based on time-series Landsat data. We find that the patterns reflected in these two datasets are statistically different, indicating a distinctive shift in land-use, which we link to the history of Inka and Spanish colonialism and Indigenous depopulation in the 15th through 17th centuries AD as well as the growth of road infrastructure and economic change in the recent past. While there is a statistically significant relationship between areas of ancient terracing and modern-day patterns of deforestation, this relationship ultimately explains little (6%) of the total pattern of modern forest loss, indicating that ancient land-use patterns do not seem to be structuring modern-day trajectories of land-use. Together, these results shed light on the long-term history of land-use in Amazonas and their enduring legacies in the present.
