Several extraordinary rainfall events have occurred in Denmark within the last few years. For each event, problems in urban areas occurred as the capacity of the existing drainage systems were exceeded. Adaptation to climate change is necessary but also very challenging as urban drainage systems are characterized by long technical lifetimes and high, unrecoverable construction costs. One of the most important barriers for the initiation and implementation of the adaptation strategies is therefore the uncertainty when predicting the magnitude of the extreme rainfall in the future. This challenge is explored through the application and discussion of three different theoretical decision support strategies: the precautionary principle, the minimax strategy and Bayesian decision support. The reviewed decision support strategies all proved valuable for addressing the identified uncertainties, at best applied together as they all yield information that improved decision making and thus enabled more robust decisions.

New climate change realities are no longer a doubtful phenomenon, but realities to adapt and live with. Its cogent impacts and implications’ dispositions pervade all sectors and geographic scales, making no sector or geographic area immune, nor any human endeavor spared from the associated adversities. The consequences of this emerging climate order are already manifesting, with narratives written beyond the alterations in temperature and precipitation, particularly in urban areas of semi-arid region of South Africa. The need to better understand and respond to the new climate change realities is particularly acute in this region. Thus, this chapter highlights the concept of adaptation as a fundamental component of managing climate change vulnerability, through identifying and providing insight in respect of some available climate change adaptation models and how these models fit within the premises and programmes of sustainable adaptation in semi-arid region with gaps identification. The efforts of governments within the global context are examined with households’ individual adaptation strategies to climate change hazards in Mopani District. The factors hindering the success of sustainable urban climate change adaptation strategic framework and urban households’ adaptive systems are also subjects of debate and constitute the concluding remarks to the chapter.

Water Quality Sensors

In the last decades, the growth of mini- and micro-industry in urban areas has produced an increase in the frequency of xenobiotic polluting discharges in drainage systems. Such pollutants are usually characterized by low removal efficiencies in urban wastewater treatment plants and they may have an acute or cumulative impact on environment. In order to facilitate early detection and efficient containment of the illicit intrusions, the present work aims to develop a decision-support approach for positioning the water quality sensors. It is mainly based on the use of a decision-making support of the BDN type (Bayesian Decision Network), specifically looking soluble conservative pollutants, such as metals. In the application and result section the methodology is tested on two sewer systems, with increasing complexity: a literature scheme from the SWMM manual and a real combined sewer.

In the Philippines, agriculture plays a vital role because this sector can contribute a lot in the development of the economy. The value of documenting the agriculture growth annually and the problems encountered is being done by the government particularly, the Department of Agriculture (DA) to come up with interventions or programs to support the Filipino farmers, both in rural and urban areas. Hence, this study focused on determining the farmers’ awareness on climate change and their adaptation strategies in one municipality in Batangas Province. By employing mixed method through self-made questionnaire and focus group discussion, this study revealed that respondents are highly aware on climate change and the best strategy to use in adapting to climate change was conservation agriculture. The study offered recommendations that different authorities can employ to strengthen the farmer’s awareness and adaptation on climate change.

Urban Adaptation

 This paper explores the importance of adaptation to climate change impacts in urban areas. The complexity of existing and likely impacts poses unique challenges to all aspects of society, from state to polity and economy. These in turn pose methodological challenges to academic practice, demanding the integration of macro and micro perspectives and pure and applied research. The paper argues that geographers can make significant contributions to this scholarship.

This article aims to gain insight into the governance capacity of cities to adapt to climate change through urban green planning, which we will refer to as climate-greening. The use of green space is considered a no-regrets adaptation strategy, since it not only absorbs rainfall and moderates temperature, but simultaneously can contribute to the sustainable development of urban areas. However, green space competes with other socio-economic interests that also require space. Urban planning can mediate among competing demands for land use, and, as such, is potentially useful for the governance of adaptation. Through an in-depth case study of three frontrunners in adaptation planning (London, Rotterdam, and Toronto), the governance capacity for climate-greening urban areas is analysed and compared. The framework we have developed utilizes five sub-capacities: legal, managerial, political, resource, and learning. The overall conclusion from the case studies is that the legal and political subcapacities are the strongest. The resource and learning sub-capacities are relatively weak, but offer considerable growth potential. The managerial sub-capacity is constrained by compartmentalization and institutional fragmentation, two key barriers to governance capacity. These are effectively blocking the mainstreaming of adaptation in urban planning. The biggest opportunities to enhance governance capacity lie in the integration of adaptation considerations into urban-planning processes, the establishment of links between adaptation and mitigation policies, investment in training programmes for staff and stakeholders in adaptation planning, and providing infrastructure for learning processes.
