The Impact

Mountain flood disasters in China’s southeastern coastal watershed are not predictable and are sudden. With rapid urbanization and development in the middle and lower reaches of the region, the accumulation of wealth and population has magnified the flood risk. Exploring flood numerical simulation technology suitable for the rapid economic development of mountainous basins, effective flood models are the key tools for controlling and mitigating flood disasters. In this paper, we established a 1D/2D real-time dynamic coupling hydraulic model, aimed at exploring the applicability of the model in flood simulation of mountainous river basins with rapid economic development. The Luojiang River Basin (Huazhou Section) in Guangdong Province was used as the case study. The model’s ability was validated against the 22 July 2010 and 14 August 2013 inundation events that occurred there. The simulation results show that the output of the flood model is highly similar to the observation and survey results of historical flood events. The research results prove that the 1D/2D coupling model is not only an applicable tool for exploring flood spread characteristics such as flood range, velocity, depth, arrival time, and duration, but also can feed back the impact of water conservancy projects such as dikes on flood spread in the basin. It is of great significance to effectively guide the comprehensive design and management of subsequent wading projects in mountain river basins, and to improve flood prevention and disaster reduction capabilities in mountain areas.

History Of

Traditionally, urbanization is hailed as an important force for socio-economic development of countries. In fact, recent research on Africa suggests that urbanization has the potential to stimulate socio-economic development. Yet, many African countries experiencing rapid urban growth continue to bear a disproportionate amount of the costs associated with urbanization (e.g., increased urban poverty, and energy crisis among others). This is in sharp contradiction to the popular notion that urbanization is a stimulus for socio-economic development. Using Ghana as a case study, this chapter discusses the extent to which rapid urbanization influences power supply and the implications on socio-economic development. The chapter focuses on four issues: (1) the history of power and urbanization in Ghana; (2) the influence of urbanization on power crisis in Ghana; (3) the socio-economic implications of urbanization-induced power crisis; and (4) the policies available in addressing the power crisis. Recommendations to address the ever-growing demand for electrical power are proffered

The Impact

This extended abstract discusses local content opportunities in economic development for the Aboriginal community. Local content requirements have become a strategic community development consideration during the past few years. This abstract links the topics of local content commitments and indigenous economic development via leveraging relationships with indigenous contractors in Australia. The creation of indigenous businesses that strive to succeed in the market and compete with non-indigenous companies is key in developing sustainable working opportunities for indigenous Australians. Many oil and gas players have publicly committed to contribute to indigenous business participation offering contractual opportunities and designing capacity-building programs and initiatives. The market for indigenous contractors services is, therefore, rapidly growing and presents considerable opportunities for existing and new players providing services to the resources industry in Australia. The specific demand is driven by corporate social responsibility policies and by the limited capacity of suppliers to deliver what is required by large new and expansion projects in the resource (both mining/oil and gas) sectors in Australia to maintain their social licence to operate. We present the results of a survey about policies and practices of some of the leading oil and gas operators in Australia, highlighting best practices in indigenous business engagement. We also analyse (from interviews with indigenous enterprises) barriers and issues encountered so far in indigenous contracting. International examples about the impact that indigenous enterprises can have on local community social and economic development complement the survey. Note: the term indigenous as used in this extended abstract refers to Aboriginal and Torres Strait Islander Australians.

The Relationship

China is in a period of rapid urbanization. Due to the high concentration of population and industries, the loss due to flood and waterlogging is becoming more and more serious. Therefore, it is of great significance to strengthen the analysis and evaluation of the losses due to flood and waterlogging disasters in China for the recent years. This study analyzed the losses caused by flood and waterlogging disasters in China from 2006 to 2017. The results showed that the most serious year affected by floods and waterlogging was 2010. However, the relationship between rainfall and flood disaster losses was not significant, which may be because the occurrence of flood disasters is caused by many factors. The spatial distribution showed that the eastern and southern parts of China suffered greater losses from the flood and waterlogging disasters because these areas are more vulnerable to floods and waterlogging disasters under the impact of both monsoons and typhoons. This study hopes to provide some reference for flood disaster control and disaster mitigation in the future.

The Impact

Urban land expansion plays an important role in climate change. It is significant to select a reasonable urban expansion pattern to mitigate the impact of urban land expansion on the regional climate in the rapid urbanization process. In this paper, taking Wuhan metropolitan as the case study area, and three urbanization patterns scenarios are designed to simulate spatial patterns of urban land expansion in the future using the Partitioned and Asynchronous Cellular Automata Model. Then, simulation results of land use are adjusted and inputted into WRF (Weather Research and Forecast) model to simulate regional climate change. The results show that: (1) warming effect is strongest under centralized urbanization while it is on the opposite under decentralized scenario; (2) the warming effect is stronger and wider in centralized urbanization scenario than in decentralized urbanization scenario; (3) the impact trends of urban land use expansion on precipitation are basically the same under different scenarios; (4) and spatial distribution of rainfall was more concentrated under centralized urbanization scenario, and there is a rainfall center of wider scope, greater intensity. Accordingly, it can be concluded that decentralized urbanization is a reasonable urbanization pattern to mitigate climate change in rapid urbanization period.

The Impact

This article examines declining adult human stature in the nineteenth century in three countries: the United States, England, and the Netherlands. While this was not unprecedented, these three relatively important nations did experience a deterioration in the biological standard of living at a time when economic development was proceeding at a goodly pace. England and the Netherlands were among the most urbanized countries in Europe at the time, while the United States was still predominantly rural and agrarian. The essay argues that a confluence of circumstances contributed to the worsening of the physical condition of these populations even while real income per capita was growing. Among the factors involved were rapid urbanization without adequate public health and sanitation; a transport revolution and related commercialization, which brought people and goods into much closer contact; the consequent integration of disease environments, both within and across nations; and a growing dependence of the working populations on wage income along with a probable growing inequality in wealth and income, exacerbating the impact of fluctuations in food prices. Technological change had an impact on these events by lowering the relative prices of industrial goods. While the term Malthusian crisis (i.e., a shortage of subsistence followed by a rise in mortality) seems inappropriate in these cases, a similar process may have been taking place. It suggests that such a crisis may not commence with an increase in mortality but rather with an adjustment of the human organism to new nutritional circumstances.
