Continuous Demand

Urban growth is one of the indicators that reflects human interaction with the environment and has a direct effect on land use change. Continuous demand for space in Nigeria’s urban markets to accommodate shops and other retail outlets used for informal economic activities is accompanied by a change of use. This study examined the impact of informal economic activities on change of use in Bola Ige International Market, Ibadan. The concept of informal economy and the bid rent theory provided the conceptual/theoretical framework for this study. Geographical Information System was used to capture the change of use between 2006 and 2016. Land used for informal economic activities increased from 39.45% in 2006 to 55.35% in 2016, signifying a 15.9% increase. This implies that other land uses have been illegally converted and encroached. Transportation land use decreased from 31.47% in 2006 to 30.28% in 2011 and to 28.73% in 2016. Land used for open space (including parking space, and open trading area) which was 26.7% in 2006 reduced to 20.24% and 11.05% in 2011 and 2016, respectively. Most of the green areas (62.1%) have been converted to informal trading spaces between 2006 and 2016. Illegal change of use was credited to harsh economic condition in the country, and the engagement of the unemployed and retirees in informal sector economic activities. It was suggested that urban managers in conjunction with informed activists, researchers and citizens need to formulate and implement planning regulations that will integrate informal economic activities.

Abstract Climate change (CC) and land use/cover change (LUCC) are the main drivers of streamflow change. In this paper, we investigate the impact of climate and LULC change impact on stream flow of Guder catchment by using Soil and Water Assessment model (SWAT). The scenarios were designed in a way that LULC was changed while climate conditions remain constant; LULC was then held constant under a changing climate and combined effect of both. The result shows that, the combined impacts of climate change and LULC dynamics can be rather different from the effects that follow-on from LULC or climate change alone. Streamflow would be more sensitive to climate change than to the LULC changes scenario, even though changes in LULC have far-reaching influences on streamflow in the study region. A comprehensive strategy of low impact developments, smart growth, and open space is critical to handle future changes to streamflow systems.

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.

The decline in the quality of ecosystem services in Bogor Regency is indicated by the existence of various natural disasters in recent years. Prudent development must be carried out to minimize the impact of a decrease in the ecosystem services index. The purpose of this research is to map ecosystem services for food supply, water supply, water and flood management, and tourism aspects within 2000-2017. The data used were land cover and land facet maps at a scale of 1:25,000 obtained from BIG, accompanied by a reinterpretation process. The data sources were Indonesia's topographic maps (RBI), Citra SPOT 7, DEMNAS, and field surveys. The ecosystem services index (ESI) is calculated based on an analysis of changes in land use and land facets. The value of ESI was weighted using analytic hierarchy process approaches to each of the variables assessed by experts. The results showed that the largest changes in land use occurred in residential and forest areas. The residential area increased by 1.96%, while the forest area decreased by 1.8% in 17 years. Bogor Regency is dominated by forest and rice fields which are spread over four main landforms, namely volcanic, structural, fluvial, and karst. The most significant increase of 5.65% was found in the clean water provisioning function, while the most significant decrease of 38.47% was found in the tourism and ecotourism sector. Accumulatively, the increase in ESI was 23%, while the decrease was 20.64%.  Mitigation efforts that can be done are to maintain the availability of green open space by implementing strong regulations.

Abstract - This paper reveals how the land use change process occurred due to the construction of post-tsunami relocation housing environments, and its impact on the pattern of daily economic activities of local communities in the coastal hilly areas. This study is important along with UU no. 24 Tahun 2007 concerning disaster management that disaster reconstruction activities must take into account the character of the local community and environmental sustainability. The phenomenological approach in this study is by observing the symptoms of the interaction between the artificial environment of the estate settlement, rural environment, and local residents-immigrants and the impact of the system's sustainability in the region. The data such as: 1) pre-tsunami and current land use maps (2020); 2) observation data, regarding daily activities of economic activities in the area; 3) interviews with community leaders to explain the dynamics of local people's economic activities. The analysis method uses a manual interaction diagram system, to read the causality structure which analyzed with “logic of space”. The results are: a) the location of relocated housing has shifted the location of livestock grazing and agricultural gardens towards hills as well as developing mining business activities C about 0.5-1Km from the housing, which is at risk of natural hazards; b) the housing environment somehow hinders the people’s daily freedom of movement and livestock towards the hills. Livestock sometimes cross residential areas and even eat plants in house yards and green open spaces and these disturb the comfort of residential residents. The conclusion is that the pattern of placing the relocated housing environment has created “space in space” which changes the pattern of community home-range activities. Suggestions for the sustainability of the economic life of local residents and the comfort of living for newcomers are the need for a strategy to organize an official route of movement to the hills and to make improvements to land for the hills, as well as the obligation to permanently fence off the housing environment. Both things are done with systems approach and synergize the interests of local communities and migrant communities. Keywords – relocated housing, vernacular settlements, hilly coastal areas, spatial behavior, Aceh Besar

The Impact

Agricultural expansion and urban development without proper soil erosion control measures have become major environmental problems in Cambodia. Due to a high population growth rate and increased economic activities, land use and land cover (LULC) changes will cause environmental disturbances, particularly soil erosion. This research aimed to estimate total amounts of soil loss using the Revised Universal Soil Loss Equation (RUSLE) model within a Geographic Information System (GIS) environment. LULC maps of Japan International Cooperation Agency (JICA) 2002 and Mekong River Commission (MRC) 2015 were used to evaluate the impact of LULC on soil erosion loss in Stung Sangkae catchment. LULC dynamics for the study periods in Stung Sangkae catchment showed that the catchment experienced a rapid conversion of forests to paddy rice fields and other croplands. The results indicated that the average soil loss from the catchment was 3.1 and 7.6 t/ha/y for the 2002 and 2015 periods, respectively. The estimated total soil loss in the 2002 and 2015 periods was 1.9 million t/y and 4.5 million t/y, respectively. The soil erosion was accelerated by steep slopes combined with the high velocity and erosivity of stormwater runoff. The spatial distribution of soil loss showed that the highest value (14.3 to 62.9 t/ha/y) was recorded in the central, southwestern and upland parts of the catchment. It is recommended that priority should be given to erosion hot spot areas, and appropriate soil and water conservation practices should be adopted to restore degraded lands.

The effects of alternative agricultural land use scenarios in terms of environmental impact assessment on surface and ground water were simulated by means of combined socio-economic and environmental models. The economic model produced and evaluated alternative farming systems, defined in terms of land use (in farm crop allocations and regional statistics of crop distributions) and cultivation practices as influenced by different macro-economic scenarios of agricultural policies. These scenarios were defined on the basis of the present Common Agricultural Policy of the European Union and possible future measures for reducing the impact of current agricultural systems on the environment. The farmers' decisional process has been simulated with multi-objective functions aimed at maximising profits and minimising risk. The methodology for the environmental impact assessment of farming systems is based on a simulation model for non-point source agricultural pollution which determines the impact of agriculture on a single field basis as influenced by environmental variables (soil and climate) and farmers' decisions (crop, soil management, fertilisation, etc.). The results obtained from this model were used to calculate a series of comparative indices capable of describing the effects of the use of fertilisers and pesticides on surface and ground waters. A geographical information system supported the spatial data management in particular for: a) the definition of simulation environments; b) the integration of physical and statistical geographical information; c) the cartographic presentation of results and the comparison of alternative scenarios. The model has been applied in the area of the Watershed of the Lagoon of Venice (WLV), located in northern Italy and has demonstrated how alternative policy scenarios determine not only significant variations in the overall environmental impacts in the study area, but also remarkable differences in their spatial distribution.

Culture has a very important essence in people's lives. Values that lead to culture seem to be the “breath” for the survival of society. A well-developed culture that can be viewed from both physical and non-physical aspects inherited from generation to generation becomes a tradition that has strong local wisdom. Yet along with its development, its existence may undergo a shift. This condition may exist because of the presence of other cultures that intentionally brought by or unintentionally emerge along with the presence of immigrants. This study aims to identify the shifts of cultural values of the people in Prawirotaman Village, especially in the aspect of community economic activities, through several stages such as: (1) Mapping changes in residential spatial planning in Prawirotaman Village; (2) Exploring economic activities changes in Prawirotaman Village. The results of the study indicate a change in governance and use of land in Prawirotaman Village. This change indeed has implications to socio-economic activities and most particularly to economic or livelihood system.

Abstract Conservation of carnivores involves finding solutions to minimize habitat loss and human-wildlife conflicts, and understanding the nature of land-use economics can allow us to mitigate both threats. In the Pantanal, the two main economic activities are cattle ranching and ecotourism, each of which directly and indirectly affect the persistence of jaguars (Panthera onca). To understand how the geography of these economic activities is related to jaguar populations, we developed a jaguar distribution model (JDM), livestock density model, and ecotourism lodge density model for the Pantanal. Due to the recent wildfires within the Pantanal, we also assess the impact of burnt areas that are suitable for jaguars, cattle ranching, and tourism. Our JDM indicate that 64% of the Pantanal holds suitable habitat for jaguars. However, jaguar habitat suitability was positively correlated with ecotourism, but negatively correlated with areas most suitable for intensive cattle-ranching. This demonstrates a biome-wide scenario compatible with jaguar conservation. Of particular concern, recent wildfires overlap most suitable areas for jaguars. If wildfires become increasingly frequent, this would represent a serious threat to jaguars and many other wildlife populations. We emphasize the global importance of the Pantanal wetland ecoregion as a key stronghold for long-term jaguar conservation.

Water quality models are useful tools to understand and mitigate eutrophication processes. However, gaining access to high-resolution data and fitting models to local conditions can interfere with their implementation. This paper analyzes whether it is possible to create a spatial model of nutrient water level at a local scale that is applicable in different geophysical and land-use conditions. The total nitrogen and phosphorus concentrations were modeled by integrating Geographical Information Systems, Remote Sensing, and Generalized Additive and Land-Use Changes Modeling. The research was based on two case studies, which included 204 drainage basins, with nutrient and limnological data collected during two seasons. The models performed well under local conditions, with small errors calculated from the independent samples. The recorded and predicted concentrations of nutrients indicated a significant risk of water eutrophication in both areas, showing the impact of agricultural intensification and population growth on water quality. The models are a contribution to the sustainable land-use planning process, which can help to prevent or promote land-use transformation and new practices in agricultural production and urban design. The ability to implement models using secondary information, which is easily collected at a low cost, is the most remarkable feature of this approach.

<p><em>Solo Baru </em><em>region</em><em> has a very strategic location and were originally intended for residential areas, but then experienced a rapid development of economic activities. The development of economic activity is the most visible trade activities and services that continue to increase precisely since 2002. The development of trade and services activities is of course have an influence on land use changes that occur rapidly in Solo Baru </em><em>r</em><em>egion. Based on these issues, the formulation of the problem in this research is how the influence brought about by the development of the activity of trade in services to changes in land use. In line with these problems, this study aims to determine the effect of the development of trading activities and services to changes in land use Solo Baru Region. The method used is quantitative descriptive to determine the level of development to later described spatially. These results indicate that the development of trade and services activities has encouraged the development of other activities either similar activities (commercial) as well as supporting activities (housing, public services, and industry) so the impact on the provision of land. The need for this land that drives the changes in land use, both in terms of area, intensity, and land use patterns are formed. Developments are vertically making it more influential in the development of land compared to the intensity of the land area. Besides land development patterns that are formed are random pattern of development as the region woke formed does not have a specific shape (sporadic) and develop segmental.</em><em></em></p><p> </p><p><strong><em>Keywords</em></strong><em>: Activities Development, Trade and Services Activity, Land Use Change</em></p>
