Abstract

This paper aims to assess the shallow crustal deformation in a highly seismic-prone zone ofnortheast India. For that purpose, Tripura University campus has been selected which isnearly 8 km away from Agartala city. The field work was conducted by using electricalresistivity meter. Vertical Electrical Sounding or VES method of resistivity survey wasadopted for measuring the electrical resistivity and structural analysis of the study area.Total four VES points were recorded namely near the Department of Physics, Department ofGeography and Disaster Management, Teachers’ Residential area and Girls’ Hostel. Therecorded data was measured and two different electrical profiles were drawn i.e. (a) Physicsbuilding to Geography buildings and (b) teachers’ quarters to Girls’ Hostel. From theelectrical resistivity profiles, a clear break in resistivity characters has been observed in thewestern part which is located near the Tripura University Girls’ Hostel. This clearly provesthat a deformation occurred in this area below 4 m depth and it can be very dangerous if ahigh magnitude seismic slip takes place. From this observation, this hostel is detected as themost risk prone building. Apart from that, the teachers’ quarters near the Girls’ hostel havealso been detected as equally risk prone. From this point of view it can be recommended thatconstruction of heavy buildings should be restricted in Tripura University campus as thesubsurface deformation zone can create faulting during high magnitude earthquake.

Abstract

Urbanization is synonymous with environmental challenges. In developing countries, thechallenges have assumed higher dimensions proportionally due to multifarious issues of rapidchanges in the environment, due to development, through population growth andindustrialization, and accompanied by all kinds of pollution such as air pollution, wastedisposal, land use degradation, and vehicular pollution as the resultant effects of man’sinteraction with the environment. The main characteristic effect is the raised temperature of thecity centre (UHI) leading to excessive energy use for cooling and putting urban population atgreat morbidity and mortality risks. This paper literally explores the conceptual framework ofinteraction between urbanization structure and understanding social impacts of climate changeand variability for the evaluation of strategies in the urbanized environment that might serve asadaptive response to climate change. The urbanization structure that affects Lagos state isdiscussed in relation to the location of the city, the size, the population density, urbangeometry, thermal property, air pollution, land use pattern, wind speed and anthropogenicactivities. The study revealed that climate change is posing increasing challenges for citiesplacing greater stress and impacts on multiple social and biophysical systems, including urbaninfrastructure, water and energy demand simultaneously, followed by a strong global trendtowards urbanization of urban poverty. The study concluded that climate change has impactedgreatly on virtually all the socio-economic aspects of man.

Abstract

Urban land use (also known as spatial planning or urban form) has a big influence andimpact on the way transport systems are planned and managed in large cities. In Kampalafor example, transport systems are largely inefficient because of the failure by the cityauthorities to adopt an integrated approach towards land use and transport planning. Due toa multifarious and complex land tenure system, the provision of roads and other transportrelatedinfrastructure such as parking facilities and bus terminals has become virtuallyimpossible. This paper examines the impact of land use on transport planning in Kampala inview of the city’s recent experience. It also draws lessons from the experiences of the rolemodel cities in Asia. To address key transportation challenges such as rapid motorizationand traffic jam, it is critical that land use-based strategies such as transit malls, land valuecapture, constructing high density buildings (both commercial and residential) along thetransit lines as well as establishing park and ride facilities are adopted by the urbanmanagers and city policy makers.

Abstract

The positive impacts of urban parks on human health have been analysed in many studies,but nearly none of them provide a suitable method to explain quantitatively the satisfactionand dissatisfaction of park uses on personal health. Bayesian Belief Network (BBN) wasemployed to examine individually well-being spirit in relation to the changes of quality ofparks and the joyfulness on access to parks. This study aims to find answers for questions‘why and where are people happy or unhappy with their health in connections to urbanparks?’ The data for Brisbane area were extracted from the quality of life survey in South-East Queensland, Australia. 70% data was used for learning model parameters; the rest wasfor model testing. The generated model had 73.17% accuracy, and it was imported to ArcGISfor constructing probabilistic maps. Due to the high density of sample points, InverseDistance Weighted (IDW) interpolation was chosen to illustrate the probable happiness andunhappiness on personal health. The result shows that quality of urban parks controlledstrongly the fulfilment of personal health. Local governors can successfully enrich the qualityof urban lives by improving the quality of parks in some specific regions.

Abstract

The economic, social, cultural and physical environment of man is interrelated with climatechange. This can be justified by several cities and people, particularly in developingcountries facing alarming threats of climate change. Scholars affirmed that low or poorcapacity to mitigate climate change in most developing cities would in long term swamp thenatural and human capacity systems required to adapt to prevailing impacts of climatechange. The impacts of climatic change on socio-economic activities have being a disturbingdevelopmental issue for governments in developed and developing world. In Most countriesclimate change is a notable environmental factor that shape and re-shape sources oflivelihoods. It has over time forced vast number of people into shackle of poverty throughdestruction of their means of livelihoods. This in recent time manifested in the lost ofproperties, lives, and destruction of infrastructural facilities. This paper unveiled the nexusbetween global climate change and livelihoods. It explored the concepts of livelihood andvulnerability in relation to climate change and its consequent impacts on livelihoods. Thepaper also examines the roles of governance towards adapting and mitigating the effects ofclimate change. It emphasized the need for improved infrastructural facilities, environmentaleducation/ enhanced climate change awareness programme, improved and monitor physicalplanning activities, good/effective governance and establishment of climate change insurancescheme.

Abstract

The patterns and trends of extreme daily rainfall within period of 1981 – 2010 have beenanalyzed for Java Island, Indonesia particularly East Java Province. A set of extreme indicesrecommended by WMO were calculated using high quality data from 84 rain stations toexpress the frequency and intensity of those events. The spatial patterns was identified bymapping climatological mean of indices while temporal trends was assessed using the nonparametricMann-Kendal test. The study found that the spatial pattern of extreme rainfallevents over East Java Province is generally characterized by low frequency and intensity inthe coastal area, and high frequency and intensity in the mountainous area. The dominantfinding from trend assessment is not-significant trend. However, the consistently significanttrend was observed in some districts. Rain stations in District of Ponorogo, Ngawi,Bojonegoro, Gresik and Sumenep showed significant negative trend for almost all indiceswhereas significant positive trend was found in District of Surabaya and Pasuruan.

Abstract

Studies on urban and peri urban agriculture in Zambia have not adequately tackled issuespertaining to farming practices in wastewater irrigation farming. The investigated thefarming practices in relation to heavy metal contaminated wastewater irrigated farming attwo peri urban areas in Zambia. The method comprised observation of crop cultivationactivities at field plots located at intervals along transects established in the stratified landzones at the two study sites namely New Farm in Mufulira and Chilumba Gardens in Kafue.The results revealed that farming practices were characterised by traditional landmanagement farming practices and traditional multiple cropping systems which wereinfluenced by a combination of agro ecological factors as well as availability of heavy metalcontaminated wastewater which has the potential to contaminate soils and crops. Thefarming practices were based on adaptation of traditional production systems to peri-urbanwastewater irrigation farming which confirmed the results from other developing countries.
