Cities in eastern Africa have been growing at an unheralded pace, and will continue to do so for the foreseeable future. Despite this rapid urbanization, very little research has been focused on energy and the environment in urban eastern Africa. This paper contains a review of what little work has been carried out to date. Several conclusions are pointed out. First, cities throughout the region remain small and have formed largely without industrial development. ‘Urbanization without industrialization’ means that the existing urban environmental problems are attributable to inadequate provision of service and not to the industrialization-linked problems found in more developed countries. Even if economic growth improves, action will be necessary to alleviate existing environmental problems. Second, the expected rapid pace of urban growth will impose tremendous costs at all levels. Increased user costs, either through reliance on private-sector alternatives or through public-sector tariffs, must be increasingly relied upon to defray the fiscal impacts of rapid urbanization and to assure the sustainability of urban infrastructural systems. Third, as the anticipated urban growth and industrialization take place, the focus of energy and environmental planners working on cities in eastern Africa will shift from basic service provision to increasingly complex problems. These shifts will require labor and financial resources far exceeding those currently found in these countries. Fourth, although energy and environmental needs may differ according to the size of the city, there has been little or no attention paid to problems outside of the primate cities. As a result, it is unclear how the problems and solutions will differ across the urban hierarchy. Clearly, urban planners need to consider the importance of energy and the environment. At the same time, energy and environmental researchers must pay greater attention to urban areas.

BACKGROUND: Pesticides poisoning is most common in developing countries, whereas psychiatric medications top the list in developed countries. In this study, an analysis of deaths due to poisoning is done with respect to age, gender, nature of poisoning, type of poison, and socioeconomic status to propose some precautions to prevent deaths. MATERIAL AND METHODS: The present study is conducted after collecting details of 75 cases of intentional and unintentional poisoning who were brought to the Department of Forensic Medicine, Government Medical College, Ananthapuramu for medicolegal autopsy. Children were excluded from the study due to insufficient data. RESULTS: Total of 75 cases are selected to conduct the study. Organophosphorus poisoning tops the list. Most of the cases are suicidal in nature. Lower class people and males are involved mostly. CONCLUSION: Poisoning in India is a socio-economic problem. Regulation of sale of poisons cannot not prevent the incidence of cases. Hence a holistic approach is necessary to uplift society as a whole by solving the problems of poverty, unemployment, industrial development, adequate health care, suitable and sufficient education, etc.

AbstractThe rapid industrial development, high population growth, and rapid urbanization of Saudi Arabia have led to increased pollution and waste levels. Every day, solid waste disposal for governments and local authorities becomes a significant challenge. Saudi Arabia produces over 15 million tonnes of solid waste annually, with a population of around 29 million. The waste production per person is estimated at between 1.5 and 1.8 kg per day per person. About 75% of the population in urban areas is concentrated, making it imperative that government steps are taken to boost the country's waste recycling and management scenario. The production of solid waste in Riyadh, Jeddah, and Dammam, three of the largest cities, exceeds seven million tonnes annually, which shows the enormity of the civic body problem. During this study, the design Expert software was involved in the optimization of process parameters during the collection of municipal solid waste (MSW) from Jeddah city. The use of design experiments and numerical optimization is quite effective in optimizing the different process parameters on the overall cost. Saudi Arabia has a critical need for a resilient waste system and agile waste management system to control its municipal solid waste quickly and environmentally friendly for achieve Saudi Vision 2030. For this study design of experiment, software was employed to optimize the cost per trip, thereby considering process parameters. It is therefore essential to examine the existing practices and future opportunities for solid waste collection, storage, and disposal. This study considered that MSW generated in Saudi Arabia which is having great potential to be converted into wealth. Hence, considering the current environment situation, energy prospective and future management strategies for MSW have also been reviewed.

The article deals with two lines of economic and cultural development of the Swedish Norrbotten as a region subjected to a special exploitation and internal colonial power relations in the decades around 1900. It is in the first place the industrial modernization of basic industries and a modern employment market, which spurred the rapid urbanization of a landscape that previously barely created any urban areas. And second the article deals with the enlargement and the boundaries of the state’s educational territory during the same time-period. The position of the Sámi population in the new educational system that evolved with society’s gradual democratization is discussed within the context of internal colonization. Government policies in different areas such as urban planning, infrastructure, education and schooling based themselves in the beginning of the twentieth century on discussions of the Sámi’s ‘qualified dissimilarity’, a concept which also was meant to ‘protect’ this group. This was a government-sanctioned differentiation and a cultural segregationist policy to ensure a non-mixing of different societal and economic interests. But even more so, the purpose was to place the Sámi economic activities within cultural parenthesis, isolate the traditional way of life, devalue it and make it immutable and static, severing it from industrial development and the promises and materialization of modernity and progress.

As opposed to the traditional Marshallian Industrial District, the Rural District becomes a new concept for territorial development thanks to the qualitative changes of population occurring since 1970 in developed countries and since 1980 in Spain and Castilla-La Mancha. The urban areas are decreasing in importance and the urban hierarchy and center-periphery relations evolved into less hierarchic and multipolar relations. Rural-rural movements occurred in rural environments, from minor cores to region cores and/or higher populated cores as a reproduction of a center-periphery model at rural territorial level.

Green belts in developing or developed countries have been released because city-center development has reached a saturation point, and the strict protections and restrictions within green belts has led to an increase in opposition from local residents and property owners. However, green belt release has led to urban growth within the associated regions and cities, resulting in an increase in the temperature and the accumulation of pollutants in the atmosphere. We intend to prove quantitatively the effect of the release of green belts at the local level based on the interactions among land cover, climate, and air quality and to provide information for policy decisions accordingly. Our simulation results show that the urban areas of Jeju and Chuncheon, in South Korea, where green belts have been completely released, will increase by up to 21.83% by 2025 and 123.93% by 2020, respectively, compared to areas that have retained green belts. The simulations also show that the surface temperature within the released region of Jeju and Chuncheon will increase by up to 0.83% by 2025 and 0.03% by 2020, respectively. The average atmospheric concentrations within the released region of Jeju and Chuncheon were modelled to increase by up to 256.93% by 2025 and 337.29% by 2020, respectively.

<p>In developing countries a big issue for urban development is the growth in infrastructure in response to economic and population demands. Such development causes cities to expand and occupy the suburbs, turning them into more built up areas. The impacts of such urban growth are immediately observable in the reduction of green areas and environmental quality, and diminishing contact with the natural environment. This study will focus on green spaces in a city in a developing country to consider the effect of this urbanization. In response to urban growth in developed countries attempts have been made to link together green spaces into a form of networks. These networks are intended to conserve the function of natural areas in towns and cities while still accommodating development. The greenway or green network and ecological network are two successful approaches developed in America and Europe. This study assesses the green spaces in Makassar, an Indonesia city, to see possibility of implementing such concepts. The study begins by redefining spaces into a typology, then assessing the spaces through three stages. The first stage is biodiversity assessment. The Rapid Biodiversity Assessment, adapted from a study in the UK, is used to assess plant biodiversity as an indicator of the quality of green spaces in urban areas. This method was adjusted and simplified to reflect the limitation in resources and time. The second stage was assessment of spaces based on a target species, in this case urban birds. The third stage combines the biodiversity score with consideration of space size and ownership. This stage produced different classes of spaces. These stages produced three different maps which were then overlaid to find the best quality green spaces termed ‘the most preferred spaces’. The next step was to see whether these spaces could be linked up in a network and to determine what sort of network could be achieved. In this part of the analysis spaces are grouped into main patches and scattered small patches, termed stepping stones. With this approach the potential connectivity can be observed visually. This study also acknowledged the significance of areas of ecological quality outside the main city but within the greater urban region and proposed connection of the network of spaces outward towards two natural parks, which could be considered as the main ecological patches. Having assessed the two main elements of a green space network—patches and corridors—through visual observation of the maps generated by the fieldwork, this study concludes that currently an ecological network is not feasible for the city because of the condition of the green spaces that make up the patches and corridors. Even a greenway along the main river corridor is not currently feasible because the highly valuable natural remnants have been significantly fragmented by cultural activities. Similarly, the road corridors are also not currently in a promising condition. The thesis ends with recommendations for the improvement of these.</p>

This novel study explores the driving forces and dynamics of rapid urbanization, highlighting the main causes and effects of urban explosion, environmental disruption, and city pattern transformation. This study was carried out that how urbanization and urban sprawl have influenced the structure of the city of Sulaymaniah in Kurdistan region of Iraq. This is because over the years many urban areas have experienced dramatic growth and population explosion that has resulted in the exhaustion of social amenities in the concerned communities. For this purpose, a qualitative method is used based on in-depth face-to-face interviews with local authority, including planners, architects, and experts of master planning, as well as professors in the academic institutions. This study also utilizes extensive document analysis to present the evolution of urban growth. The findings reveal that the autonomy, political conflict, non-implementation of master plans, and economic prosperity are the driving forces which are accelerating this urbanization process. It is proposed that the practical policies and strategic urban development plans are urgent requirement to control the unplanned urban growth and stimulate the desired sustainable future urban development.

One of the environmental problems in urban areas is the pollution caused by garbage. The waste problem is caused by various factors such as population growth, living standards changes, lifestyles and behavior, as well as how the waste management system. This study aims to determine how the role of society to levy payments garbage in Samarinda. This research was descriptive; where the data is collected then compiled, described and analyzed used relative frequency analysis. The participation of the public to pay a "levy junk", which stated to pay 96.67%, for each month and the rates stated society cheap, moderate and fairly, respectively 46.08%, 21.21%, 21.04%. Base on the data , the role of the community to pay "levy junk" quite high.

During the last few decades there has been a sharp transition in economic doctrine, within the context of economic growth, on the relative contributions of agriculture and industrial development. There has been a shift away from the earlier 'industrial fundamentalism' to an emphasis on the significance of growth in agricultural productivity and production. The focus, especially in the context of the present-day less developed countries like Pakistan, has sharpened with the rapid growth in demand for food, resulting from the increasing growth in population and the high income-elasticities of the demand for food. Coupled with this is the transition from resource-based agriculture to science-based agriculture. Agricultural economists are unanimous in the view that by the end of this century all increases in world food production will come from higher yields, i.e. increased output per hectare. This increasing emphasis on 'land-saving' technology to increase productivity and production has resuited from the growing population pressures on land and declining land-man ratios. Agricultural research has come to the fore in providing technologies that increase productivity and production. However, these technologies do not explicitly take into account the equity aspects of the problem. The extent to which the poor gain or lose from the introduction of a new agricultural technology depends on a host of complex and interrelated socio-economic and political factors such as the existing distribution of productive resources, access to modem inputs, the structure of the market, etc.
