    The water security issue is worsened by the presence of the global threat of climate change that may inhibit global and local water availability. This study explores water security from the perspective of three impelling factors and was carried out in Bangkok Metropolitan Region (BMR), Thailand. We define the trilemma as three generally conflicting factors that bring different consequences because of water security. The study was organized by accounting time-independent hydrological budget in the region comprises of surface water, probable atmospheric water, and groundwater against current and future water demands with particular water qualities for different purposes. A sensitivity analysis has also been done. The study found that with current water resources development and water demand, the BMR would unlikely encounter water security issues, given the existing trilemma as a constraint. However, with a continuous increase in water demand and unchanged supply, water scarcity would likely be faced by BMR, as analysis suggests.

    The zero-waste term in municipal solid waste management has been the utopian objective of every waste management authority in the cities in developing countries, even though it comes with different perceptions, which are sometimes misguided. People can produce no waste unless they live with no consumption. The zero-waste term does not mean that we produce no waste, rather we dump no waste at the landfill site. It means we dispose of nothing at a landfill site since the issue of landfill site can be a culprit of waste management, for its reiterating city land demands that generate “headaches” to city authority because of NIMBYism (Not In My Back Yard issue). No one accepts living voluntarily next to a landfill site as it creates more harm than harmless. With zero waste at the landfill site in mind, the waste management authority attempts to deal with the complexity of municipal solid waste management, by reviving each element of the waste management stakeholders to concertedly move on to deal with waste. Individual households and communities, without which waste management will not be successful, were positioned as the main thrust of waste management. A multipronged approach was implemented with all stakeholders, i.e., lawmakers, regulators, waste producers, implementers, and pressure groups, appearing with different functions but a common point: zero waste at the landfill site. A stakeholder with a large capacity, i.e., local government focuses on creating a large project that has a large impact on overall waste management; private sectors may contribute to establishing recycling centers, and waste-to-energy projects. Meanwhile, the individual households, which are large in number but have a small capacity, establish community-based activities, i.e., waste banks. This chapter attempts to provide the overall picture of municipal solid waste management in 14 cities in developing countries toward their goal of zero waste at landfill sites.
