“…Figure 4, contains images of the museum. Due to the effects of climate change, it is expected that this region will suffer negative impacts [45,46], floods being one of the most important. As it is well known, floods cause billions of euros of damage every year and due to climate change, their impact is expected to increase [47].…”

Governance Assessment of the Flood’s Infrastructure Policy in San Pedro Cholula, Mexico: Potential for a Leapfrog to Water Sensitive

Climate change together with population growth and land-use change have increased the risk of urban floods. Urban floods cause severe damages to cities and their inhabitants, and they are expected to increase over time. Consequently, urban adaptation is required to shift from traditional infrastructure (grey) to multifunctional infrastructure (blue-green) for improved flood management. Until recently, studies on the role and adoption of blue-green infrastructure have centered around large cities in developed countries, including Melbourne and Rotterdam, among others. Meanwhile, middle-sized cities in developing countries have received less attention. According to the Urban Water Management Transition Framework (UWMTF), cities in developing countries can learn from the experiences of developed cities and leapfrog to more 'water sensitive' practices. Although leapfrogging is context-dependent, our understanding of factors that support leapfrogging remains embryonic. This paper contributes to the scholarly understanding of the governance factors that support and limit leapfrogging. By applying the Governance Assessment Tool through semi-structured interviews and reviewing secondary data, this research assessed the implementation of flood protection infrastructure in San Pedro Cholula, a middle size city of Mexico. This work found the most supportive quality for delivering multifunctional infrastructure, was the extent of the governance system. The governance support extent was rated as moderate-low considering the platform for change is limited to government actors, which has further reinforced traditional approaches to infrastructure. In addition, the necessary governance features of coherence, flexibility and intensity were assessed as constraining change, with flexibility being the least supportive governance factor and ultimately hindering social actors' participation and innovation. While the contemporary governance arrangements of San Pedro Cholula are not yet conducive to promoting a leapfrog in the delivery of urban flood infrastructure, the analysis has pointed to three catalytic factors to underpin a leapfrogging situation: trans-disciplinary science; cross-sector partnerships; and, innovation experiments.

“…Earlier studies on the city of Lagos identified the basic climate change risk components in the city [9,10]. Flooding, sea level rise, storm surge, high temperature and high rainfall intensity constitute the notable hazards and high vulnerability levels which are shaped by Lagos' high population density, large poor population, low lying topography and coastal location [11].…”

“…For example, research on the effects of climate change on water and waste water management has revealed that flooding and associated pollution will greatly reduce the water quality and potable water quantity in the state [10]. Further studies have also noted that numerous highly populated communities within 10 km of the coastline are often inundated or submerged as a result of sea level rise or flooding [13,14].…”

“…Last but not least, a controversial issue over a resilient reclamation project was the uncertainty of trend predictions (Major et al, 2011). Three common factors that contributed to the uncertainty were: (1) long projection period, (2) insufficient data to forecast future climate scenarios, and (3) sophistication of the model (Hughes et al, 2010;Mailhot and Duchesne, 2010;O'Neill, 2010).…”

A mini-review on the impacts of climate change on wastewater reclamation and reuse

To tackle current water insecurity concerns, wastewater reclamation and reuse has appeared as a promising candidate to conserve the valuable fresh water sources whilst increasing the efficiency of material utilization. The climate change, nevertheless, poses both opportunities and threats to the wastewater reclamation industry. Whereas it elevates the social perception on water-related issues and fosters an emerging water-reuse market, the climate change simultaneously presents adverse impacts on the water reclamation scheme, either directly or indirectly. These effects were studied fragmentally in separate realms. Hence, this paper aims to link these studies for providing a thorough understanding about the consequences of the climate change on the wastewater reclamation and reuse. It initially summarizes contemporary treatment processes and their reuse purposes before carrying out a systematic analysis of available findings.
