“…But there are no technical barriers to other countries following Sweden's lead and participatory approaches can go a long way to understanding wider socio-economic and cultural obstacles. Indeed, applied geographical research has produced a wide range of environmental modelling and management tools that can integrate the views of local communities and have potential for use by local authorities that have responsibility for landuse, environmental planning and climate change adaptation (Wang et al, 2007;de Graaff, 2008;Maconachie;Zeilhofer and Topanotti;Dewan and Yamaguchi, 2009;Palm et al, 2009;Velázquez et al, 2009;Yadav et al, 2009;Mishra and Griffin, 2010).…”

“…Research that deals more directly with human waste is even less widespread although empirical work on 'watsan' (water and sanitation) issues in the global South (Andersson, 2001;Desai, 1995aDesai, , 1995bGandy, 2008;Giles & Brown, 1997;McFarlane, 2008aMcFarlane, , 2008bO'Hara, Hannan, & Genina, 2007;Jewitt and Labhsetwar, 2009;Swyngedouw, 2004, Swyngedouw, Kaiko, & Castro, 2002 and research on the analysis, modelling and prediction of water and beach contamination by sewage and other pollutants (Reeves and Patton, 2005;Kay et al, 2007;Collins and Anthony, 2008;Rahman, 2008;Anayah and Almasri, 2009) demonstrates the importance of applied geographical research on these topics. And in combination with wider geographical research on environmental quality, this work has provided some important monitoring, modelling and participatory resource management tools for improved landuse planning and environmental management which have great relevance for understanding and managing the threats and opportunities created by human excreta (He et al, 2006;Ivey et al, 2006;Wang et al, 2007;Collins and Anthony, 2008;de Graaff, 2008;Maconachie et al, 2008: Zeilhofer andTopanotti 2008;Rahman, 2008;Anayah and Almasri, 2009;Collins et al, 2009;Dewan and Yamaguchi, 2009;Kamusoko et al, 2009;Maantay and Maroko, 2009;Rhoades et al, 2009;Velázquez et al, 2009;Mishra and Griffin, 2010).…”

“…Satellite remote-sensing imagery is one of the most suitable data sources for detecting and monitoring land use changes at the regional and global scales, such as Landsat TM/ETM+ and CBERS images (Carlson and Sanchez-Azofeifa, 1999;Shalaby and Tateishi, 2007;Brink and Eva, 2009;Dewan and Yamaguchi, 2009;Qiao et al, 2009). The land use database used in this study was developed by the Data Center for Resources and Environment Sciences, Chinese Academy of Sciences, which was interpreted from different periods of Landsat TM/ETM+ imageries, and the interpretation accuracy is as high as 92.5% (Liu et al, 2005).…”

Estimation of land production and its response to cultivated land conversion in North China Plain

et al. 2011

Food safety and its related influencing factors in China are the hot research topics currently, and cultivated land conversion is one of the significant factors influencing food safety in China. Taking the North China Plain as the study area, this paper examines the changes of cultivated land area using satellite images, estimates land productivity from 1985 to 2005 using the model of Estimation System for Land Productivity (ESLP), and analyzes the impact of cultivated land conversion on the land production. Compared with the grain yield data from statistical yearbooks, the results indicate that ESLP model is an effective tool for estimating land productivity. Land productivity in the North China Plain showed a slight decreasing trend from 1985 to 2005, spatially, increased from the north to the south gradually, and the net changes varied in different areas. Cultivated land area recorded a marginal decrease of 8.0 × 10 5 ha, mainly converted to other land uses. Cultivated land conversion had more significant negative impacts on land production than land productivity did. Land production decreased by about 6.48 × 10 6 t caused by cultivated land conversion between 1985 and 2005, accounting for 91.9% of the total land production reduction. Although the land productivity increased in Anhui and Jiangsu provinces, it can not offset the overall adverse effects caused by cultivated land conversion. Therefore, there are significant meanings to control the cultivated land conversion and improve the land productivity for ensuring the land production in the North China Plain.

An integrated approach of flood risk assessment in the eastern part of Dhaka City

et al. 2015

View full text Add to dashboard Cite

The flood risk is a function of the flood hazard, the exposed values and their vulnerability. In addition to extreme hydrological events, different anthropogenic activities such as extensive urbanization and land use play an important role in producing catastrophic floods.Considerations of both physical and social dimensions are therefore equally important in flood risk assessment. However, very often the risk assessment studies either focus on physical or social dimensions. In addition, the available studies often focus on economic valuation of only direct tangible costs. In this study, we provide an integrated flood risk assessment approach that go beyond valuation of direct tangible costs, through incorporating physical dimensions in hazard and exposure and social dimensions in vulnerability. The method has been implemented in the Dhaka City, Bangladesh, an area internationally recognized hotspot for flood risk. In this study, flood hazards for different return periods are calculated in spatial environment using a hydrologic model, HEC-RAS. Vulnerability is assessed through aggregation of various social dimensions i.e., coping and adaptive capacities, susceptibility. We assess vulnerability for both baseline and improved scenario. In the baseline scenario, current early warning for study area is considered. In the alternative scenario, the warning system is expected to improve. Aggregating hazard, exposure and vulnerability, risk maps (in terms of both tangible and intangible costs) of several return period floods are produced for both baseline and improved scenario. Compared to traditional assessments, the integrated assessment approach used in this study generates more information about the flood risk. Consequently, the results are useful in evaluating policy alternatives and minimizing property loss in the study area.
