“…The difference between structural and non-structural measures relies on the fact that the former requires significant investments and generates lasting, sometimes permanent changes. At the same time, the latter presents the advantage of guaranteeing access to water in acute episodes while eluding significant investments, which could end up underused in favourable climate circumstances 56 . In line with the abovementioned need to enhance the participation of different stakeholders and promote citizen participation, various studies have also analysed this issue from the governance perspective, either focusing on improving management, monitoring, and supervision by authorities or aiming to improve water management by promoting citizen participation and engagement 57 .…”

Climate change (CC) will likely significantly impact the world’s infrastructure significantly. Rising temperatures, increased precipitation, and rising sea levels are all likely to stress critical infrastructures (CI). Rising temperatures can lead to infrastructure damage from extreme heat events. This can cause roads and bridges to buckle or crack, leading to costly repairs and potential traffic disruptions. In addition, heat waves can damage vital electrical infrastructure, leading to widespread power outages. In light of this context, this article reports on a study which examined the connections and impacts of CC on infrastructure. The study employed a mixed-method approach, combining bibliometric analysis for the period 1997–2022 with a series of relevant case studies from the five continents to offer insight into the impact of CC on infrastructure. The article fills a research gap in respect of assessments of the extent to which climate change (CC) negative influences the infrastructure, with a special focus on developing countries. It also showcases CI projects and adaptation measures being currently deployed, to address CC. The results show that the current infrastructure is vulnerable to CC. The selected case studies on CI adaptation show that in developing and industrialised countries, there is a perceived need to understand better the connections and potential impacts of CC on critical areas such as transport, settlements, and coastal infrastructure. In order to protect infrastructure from CC impacts, governments need to invest in measures such as flood control, early warning systems, and improved building codes. Additionally, they need to work to reduce greenhouse gas emissions more actively, which are the primary cause of CC.

“…The goal is to use the most sustainable strategies to maximize benefits and system effectiveness, while minimizing costs and trade-offs (United Nations Water 2021). Ricalde et al (2022) note that non-structural responses can offer positive results under uncertain conditions compared to structural responses which have higher irreversible costs. Therefore, adaptation remains a key driver in responding to climate change in the water sector.…”

Sub-catchment level water sector response strategies to climate change in Zimbabwe have not been adequately analyzed to determine their impact and connectedness with the Sustainable Development Goals (SDGs). In this study, the mixed methods research design is used to examine the implications of water sector climate change response strategies (CCRS) on SDGs in Mutirikwi sub-catchment in Masvingo, Zimbabwe. Results show that the climate is changing, with a statistically significant (p = 0.031; α = 0.05) increase in the annual mean temperature and a declining rainfall trend, though not statistically significant (p=0.753; α = 0.05). Views from local communities and stakeholders confirm the existence of climate change. There is a deluge of response strategies to the changing climate, including borehole drilling, roof rainwater harvesting, surface storage, water reuse and water transfers. These strategies have directly contributed to the achievement of SDG 6 (Clean Water and Sanitation), SDG 11 (Sustainable Settlements), and SDG 13 (Climate Action). They have also indirectly contributed to the achievement of SDG 3 (Health), SDG 5 (Gender), SDG 9 (Infrastructure) SDG 12 (Sustainable Consumption) and SDG 15 (Life on Land). The study concludes that there is an inextricable link between CCRS and SDGs. However, implementation of the response strategies is riddled with challenges that are threatening the sustainability matters. There is a need to design community-driven response mechanisms synergized with national and international climate adaptation initiatives to ensure sustainability of the strategies through guaranteed policy and resource support from the national government and non-governmental agencies.

“…Several approaches have been proposed to enable planning under deep uncertainty 26,30 ; these allow designing robust and flexible plans that maximize resilience and minimize investment costs on the basis of, for example, adaptation tipping points 31 , dynamic adaptive planning 32 and dynamic adaptive policy pathways 24,33 . Several recent studies have applied such adaptive methods to planning water resource systems in various contexts 25,[34][35][36][37][38] . For instance, a reservoir adaptive planning framework has been developed to explicitly consider learning about climate uncertainty over time 35 , and other studies have optimized the indicators, actions and/or thresholds in the design process of adaptive plans for water resource systems 33,36,39,40 .…”

Cooperative adaptive management of the Nile River with climate and socio-economic uncertainties

The uncertainties around the hydrological and socio-economic implications of climate change pose a challenge for Nile River system management, especially with rapidly rising demands for river-system-related services and political tensions between the riparian countries. Cooperative adaptive management of the Nile can help alleviate some of these stressors and tensions. Here we present a planning framework for adaptive management of the Nile infrastructure system, combining climate projections; hydrological, river system and economy-wide simulators; and artificial intelligence multi-objective design and machine learning algorithms. We demonstrate the utility of the framework by designing a cooperative adaptive management policy for the Grand Ethiopian Renaissance Dam that balances the transboundary economic and biophysical interests of Ethiopia, Sudan and Egypt. This shows that if the three countries compromise cooperatively and adaptively in managing the dam, the national-level economic and resilience benefits are substantial, especially under climate projections with the most extreme streamflow changes.
