“…For many cities around the world, warming trends in minimum and maximum daily temperatures were calculated from stations located in urban environments. For some of them, the comparison with nonurban data shows that the trends are mainly related to large-scale climate change (129,130) without significant modification by cities. Nevertheless, Lee et al (131) studied several Asian megacities and found that the urbanization dynamics between 1992 and 2012 led to a modification of climatic trends.…”

“…Some work also looked at long-time series of precipitation observations. Although several climatological studies show an effect of cities on the intensification of precipitation, there is no evidence of an impact of cities on the evolution of climate trends (129,130,134). Nevertheless, based on an integrative indicator combining temperature and precipitation data, Salvati et al (130) showed an increase in drought events at the city site (Rome, Italy) relative to the rural site between 1958 and 2017.…”

Cities are particularly vulnerable to extreme weather episodes, which are expected to increase with climate change. Cities also influence their own local climate, for example, through the relative warming known as the urban heat island (UHI) effect. This review discusses urban climate features (even in complex terrain) and processes. We then present state-of-the-art methodologies on the generalization of a common urban neighborhood classification for UHI studies, as well as recent developments in observation systems and crowdsourcing approaches. We discuss new modeling paradigms pertinent to climate impact studies, with a focus on building energetics and urban vegetation. In combination with regional climate modeling, new methods benefit the variety of climate scenarios and models to provide pertinent information at urban scale. Finally, this article presents how recent research in urban climatology contributes to the global agenda on cities and climate change. Expected final online publication date for the Annual Review of Environment and Resources, Volume 45 is October 19, 2020.

“…Addis Ababa City is highly affected by climate change, such as flooding, drought, heat waves and land slides [57][58][59][60][61]. In the city, climate change and its impacts are aggravated by an unprecedented rate of urbanization and rapid population growth, built-up-area expansion, less green-area coverage and land use change [57,[62][63][64][65]. To govern climate change in the city, the Addis Ababa City Environmental Protection and Green Development Commission (AAEPGDC) was awarded a mandate and will implement a climate-resilient green growth strategy for 10 years until the year 2025, based on the 2011 country's CRGE strategy [66].…”

Factors Affecting Climate Change Governance in Addis Ababa City, Ethiopia

2023

Climate change in Ethiopia’s capital city of Addis Ababa is characterized by an increase in rainfall and subsequent flooding and severe temperature with more heat waves. The city government has now recognized climate change as a serious threat, including it being a reason for loss of life and livelihoods. Even though governance has become a key mechanism to address a reduction in greenhouse-gas emissions and vulnerability to climate change, the practice of climate-change governance has been undermined by different factors. Thus, this study examined factors affecting climate-change governance in the city. The research adopted a mixed research design and depends on primary and secondary data sources. The binary logistic regression model and descriptive statistics were both used to analyse the quantitative data, while the descriptive method was used for the qualitative data. The results reveal that a lack of coordination, political will and leadership are the major factors that hinder the practice of governance in the city, followed by inadequate finance, policy, strategy, and regulation. In addition, a shortage of knowledgeable experts, lack of access to information and technologies had their own contributions to the ineffectiveness of climate-change governance. Thus, the city administration should place emphasis on climate change, giving it comparable weight to other crosscutting issues, and enabling the functioning of the steering committee with a strong accountability system. In addition, the city administration should take aggressive measures, including revising or formulating new policy, strategy or regulation, and even creating an independent institution for climate-change issues. Furthermore, the Addis Ababa City environmental protection and green development commission should create an enabling environment to attract non-state actors, in general, and NGOs, in particular, and should assign one directorate to mobilise finance, following the approach taken by the federal environmental protection commission. The commission should implement a mechanism to efficiently utilize the budget by applying continuous monitoring and evaluation. The commission should also provide continuous training and capacity building for leaders and experts at sub-city and Woreda levels.

“…Ethiopia is no exception; there are calls to put climate change at the centre of urban water planning in the country (Rickert et al, 2019). Climate change has prompted a 'climate study' of Addis Ababa at the urban scale (Arsiso et al, 2018), and Worku (2017) has called for a transformative approach to urban water management in the capital city in the face of climate change. In 2018, the government approved a second phase of the One WASH National Programme with a fund of 6.5 billion USD from multi-lateral and bilateral donors, in order to create climate-resilient water systems and work towards universal access to drinking water (FDRE, 2018).…”

Socio-political processes must be emphasised alongside climate change and urbanisation as key drivers of urban water insecurity

Urban water security is of critical global and local importance. Across many parts of low- and middle-income countries, urban water security either remains elusive or is becoming stressed. Rapid urbanisation and climate change are two key drivers of resource insecurity and at the forefront of urban water discourse. However, there are manifold and complex socio-political processes functioning alongside these megatrends that are often underemphasised. Drawing on three urban case studies in Ethiopia, we highlight these structural issues and the need for their continued consideration to fully understand and address urban water insecurity. Household water-use surveys, semi-structured interviews and participatory exercises with community residents, stakeholders and informal water vendors were used as part of a mixed-method approach in three urban areas. We found that government-managed urban water supplies were intermittent and unsafe, resulting in economic, health and time-use burdens for households, and that the socio-political dimensions reproducing urban water insecurity have historical roots. We argue that the uncertainty of climate change and unprecedented urbanisation do not offer sufficient explanation for why urban water insecurity persists. Moreover, we call for caution in only employing these narratives, to avoid obscuring deeply rooted challenges within socio-political systems. We call for socio-political processes to continue to be a central component of future interventions that seek to improve urban water insecurity.
