The Intergovernmental Panel on Climate Change (IPCC) IPCC (2007) projects that greater precipitation intensity and variability will increase the risks of flooding in many areas because of climate change. With climate change already happening, societies worldwide face the parallel challenge of having to adapt to its impacts as a certain degree of climate change is inevitable throughout this century and beyond, even if global mitigation efforts over the next decades prove successful (European Commission, 2007).

The fact that the world is becoming increasingly urbanized is recognized by the United Nations (UNFPA, 2007) in the State of the World Population Report as the “The Urban Millennium.” In year 1950, 30% of the world's population lived in cities and as of recently, the population has reached up to 50%, making year 2007 a turning point in the history of urban population growth (Bigio, 2003; Kreimer, Arnold, & Caitlin, 2003; UN-HABITAT, 2007). By year 2030, the United Nations expects more than 60% of population to be living in cities (Munich Re, 2005). And as shown by Surjan and Shaw (2009), by year 2050, the world's urban population is expected to grow by 3 billion people. Most of this growth will take place in developing countries, with the urban population in cities and towns doubling. As it has been summarized, from 1991 to 2005, more than 3.5 billion people were affected by disasters; more than 950,000 people have taken their lives unwillingly and damages have reached nearly 1,193 billion US dollars. Developing countries will suffer the most from climate change, since they are disproportionally affected and have intrinsic vulnerabilities to hazards and so far have struggled in increasing the capacity for risk reduction measures (Wahlström, 2009). Nevertheless, by contrast, even in the largest and wealthiest countries, which have diversified economies and risk transfer mechanisms, the loss has topped an amount of billions of US dollars, as was the case with Hurricane Katrina in USA in 2005. It has been confirmed with facts over the last two decades (1988–2007) that 76% of all disaster events were hydrological, meteorological, or climatological in nature, whether it occurred in urban or in rural areas.

Located at the center of the Red River Delta, Hanoi is the consequence of the unstable balance between soil and water and has witnessed the amicable and adverse relationship between the two elements over a long history. Established as a small town in A.D. 210, Hanoi grew from a harbor on the bank of the Red River to a thriving city and was chosen to be the capital of Vietnam in 1010 as the site had advantageous physical, landscape, and geomancy characteristics. However, the capital had also been confronted with difficulties due to the alluvial process, which raises the level of the watercourse above its normal elevation forcing the inhabitants to take measures such as building a dyke to prevent floods. This chapter analyzes the natural and social conditions as well as several problems that have been affecting urban flood risk management in Hanoi. The chapter ends with practical options and policy measures to address the problems.

The new campus of Tianjin University was designed, built and now operates following a green and sustainable concept. The campus’ eco-friendly water environment was formed by establishing a water recycling system. The campus is divided into three drainage sections based on the masterplan. Each drainage section adopts different methods of collecting, utilizing and discharging water according to specific conditions, aimed at achieving both high drainage capability and the efficient utilisation of rainwater. The campus was designed so runoff pollution is reduced through the utilisation of low-impact development methods, ensuring the quality of the recharge water. Through studying the fundamentals of treatment measures and models for simulating water quality, water circulation, constructed wetlands and pollution control of rain runoff, parameters for efficient water recycling could be mathematically forecast, ensuring that stakeholders can be continuously engaged in improving and preserving the water quality of landscaped water on campus. The overall system integrates a variety of measures being implemented into one cohesive entity, which contributes to establishing the sustainable and healthy water cycling system of the green campus.

Dams are constructed for many purposes such as for power generation, irrigation, water supply and flood control. However, dams can also impose risks to the public, and the situation could be disastrous if dam failure occurred. The study area, Bertam Valley, is located downstream of hydroelectric dam known as Sultan Abu Bakar Dam, Cameron Highlands. The key objectives of the study are to determine the potential risk area at downstream and to assess the flooding impact on damage to buildings and infrastructures due to dam break event. ArcGIS application and output from two-dimensional flood modelling have been used as an integrated approach to analyse the impact due to dam break flood, by creating flood severity grid analysis. The result obtained shows that the estimated inundated area is about 0.28 km², and almost 197 buildings are potentially affected. Results from this study show that in the event of dam break, the huge volume of impounding water will pound to the downstream areas, threatening the populations, and environment along its path. The finding is useful to assist the local authorities and emergency responders in formulating an emergency procedure to save the people during an emergency.

The Philippines is one of the most vulnerable countries in the world as far as climate-related and other forms of disasters (e.g., earthquake and volcanic eruption) are concerned (World Bank and NDCC, 2004; UNISDR, 2008a, 2008b). In 2004 alone, 25 weather disturbances hit the country, of which four occurred successively in November and the first week of December. These triggered massive landslides and flooding in Southern and Central Luzon, leading to damages in lives and properties (Duque, 2005). With this the country is considered as one of the most disaster prone, ranking 12th among the 200 countries most at risk to natural hazards in the 2009 Mortality Risk Index of the United Nations International Strategy for Disaster Reduction (UNISDR, 2009).

In the context of natural disasters and climate change, ecosystems are critical natural capital because of their ability to regulate climate and natural hazards. This chapter examines the important role of ecosystems and their services in disaster risk reduction and climate change adaptation. It discusses the relevance of adopting ecosystem-based approaches in managing risks brought about by a changing climate.

According to a report by Food and Agriculture Organization, total forest area in the world as of 2005 is estimated at 3,952 million hectares (9,766 acres) or 30 percent of total land area (FAO, 2005a). The area of forest is unevenly distributed (FAO, 2005b). At the regional level, South America is the region with the highest percentage of forest cover, followed by Europe and North and Central America. Asia is the region with the lowest percentage of forest cover (FAO, 2005c). The forest environments are changing globally. Climate change is one of the reasons, and it affects world forest management. More attention has been devoted to timber as the major commercial aspect of forests rather than to other noncommercial resource values (Barnard et al., 1985). The purpose of forest management was once as simple as taking timbers, but it is now more complicated. When the forest environments change, the key trends of world forest management must also change. Now, generally speaking, the extent of forest resources refers to an overall maintaining of adequate forest cover and stocking of various forest types and characteristics, and the ultimate aim of monitoring the extent and characteristics of forest resources is to reduce unplanned deforestation, restore and rehabilitate degraded forest landscapes, manage forests sustainably, and evaluate the important function of carbon sequestration by forests, other wooded land, and trees outside forests, thereby contributing to moderating the global climate (FAO, 2005d).

Stakeholders are typically described as those who may affect or be affected by the actions of a firm. The purpose of this chapter is to present an argument that stakeholder theory should pay specific regard to what I term marginal stakeholders, that is, parties affected by a firm’s actions but who nevertheless have no actual or foreseeable influence to shape its strategic goals. Several key proponents of stakeholder theory maintain that these groups are not legitimate stakeholders and therefore do not warrant consideration. For example, marginal groups are routinely excluded from discussions of stakeholder fairness. Alternatively, theorists presume that advocates with leverage will protect these groups, or appeals to human rights will be sufficient. In contrast, I contend that there are cases where the firm has benefitted, but identifiable and discrete stakeholders have been negatively affected by corporate action in an environment where rights are ignored or there is no significant legal recourse. Drawing on foundational literature on fairness and insights from social psychology, I conclude that fully realized stakeholder theory means that a corporation has to consider its duties to all those affected by the impact of a firm, including the powerless.
