1. Introduction
Climate change is a globally concerning issue which strongly calls for a new governance agenda in the sectors of both theory and policy [
1,
2]. The growing challenges of climate change are complex and far-reaching, requiring interventions beyond a single source and actor [
1,
3]. Environmental problems, and climate change in particular, occur in different contexts and extents worldwide and cannot be addressed successfully by a single actor [
4,
5]. Climate change with cross-boundary impacts in nature has been positively impacted through climate change governance [
2]. Climate change governance can therefore be described as the coordination of different institutions and actors, in horizontal and hierarchical forms, concerning climate change adaptation and mitigation actions [
1,
6,
7,
8,
9]. It has also been viewed as a broad range of options of coordination concerning the prevention of greenhouse gas emissions (mitigation) and adaptation to the impacts of climate change [
10,
11].
Cities around the world are key in managing global carbon emissions (mitigation) and reducing vulnerability to climate change (adaptation) [
12,
13]. Cities occupy a unique space in terms of the causes and impacts of climate change [
14]. The impacts in cities have been aggravated due to concentrated populations, high economic activity, congested transportation systems, and the construction of buildings. Furthermore, as the majority of people live in cities, more than 78% of waste is generated in cities [
14]. Studies indicate that cities contribute the bulk of greenhouse gas (GHG) emissions [
7,
15]. Although cities cover less than 5% of the world’s area [
14], they produce more than 70% of the world’s GHG emissions and use 80% of the world’s energy [
14,
16,
17].
Cities are also responsible for up to 75% of all global emissions of carbon dioxide from anthropogenic sources [
7]. Urban areas are the largest contributors to climate change through the alteration of green covers, such as forests and grasslands, for other land uses [
18]. At the same time, the projected impacts of climate change show that urban populations and infrastructure around the world are at significant risk [
19]. In the face of this, cities are sites for climate action and increasingly central to the global governance of climate change, and much of their activity takes place through the interaction of governments, private sectors, and civil society at local, regional, national, and global scales [
14,
20]. Therefore, in an urban context, climate change governance is the set of formal and informal rules, rule-making systems, and actor networks at all levels (from local to global and from state to non-state actors), which are established to steer cities towards mitigating and adapting to climate change [
6,
8,
9,
12,
21]. Climate change governance is characterized by the integration of climate adaptation and mitigation in different sectors such as energy, urban planning, transportation, water management, waste management, agriculture, health, and others that interact in various ways [
1,
22].
In the face of a growing global, national, and local environmental crises, good governance of the natural environment is deemed to be crucial not only for sustainable development but also for the harmonious existence of humanity with nature [
23]. Owing to this, there is a growing consensus among the global actors that good environmental governance has an enduring effect on environmental actions and outcomes. Hence, in general, good environmental governance is often denoted by the effectiveness in which the environmental governance measures achieve the objective of protecting the general environment from anthropogenic hazards, as well as the optimal and sound practice of the governance systems in the reduction in environmental problems [
24]. Hence, effective climate change governance must adhere to major parameters such as transparency, accountability, public participation, law enforcement, the ensuring of citizen awareness, coordination, information sharing, fairness, justice, and the involvement of actors and institutions [
25,
26,
27,
28,
29].
Although there is no single governance solution to climate change, coordination and participation among multiple actors in the reduction in GHGs, climate risk identification, and in the prioritization and implementation of adaptation measures is known to lead to more effective urban climate change governance [
30]. The effectiveness of governance in responding to climate change in cities depends on human resources, financial resources, legal frameworks, and legitimate institutions [
7,
31]. Scientific information is also necessary in creating a strong foundation for effective urban climate change governance [
32]. In addition, effective climate change solutions should include the cooperation of various institutions and actors at different levels, whether in the prevention of greenhouse gas emissions (mitigation) or in the process of adaptation to the impacts of climate change [
1,
33]. According to [
23], rule of law, citizens’ rights of access to environmental information, meaningful participation of the wider public in environmental matters, and justice are the bases for achieving environmentally sustainable development.
Effective urban climate change governance should incorporate principles of justice in order for vulnerable groups to be represented in adaptation and mitigation planning processes, issue framing, as well as recognizing their particular needs and actions [
34]. Key factors that shape responses to mitigation and adaptation measures include effective policy and strategy, coordination of different sectors, and strong municipal governance in key areas, especially in energy, transportation, and waste management [
7,
35]. Political commitment and mainstreaming of adaptation and mitigation measures in cities’ development agendas are crucial for sustainability [
36]. Having accurate scientific information about local GHG emissions and the impacts of climate change on a city is essential to take adaptation and mitigation responses [
31].
Due to the growing recognition of climate change problems as a result of GHG emissions in cities, the 1990s were seen as a turning point for climate change response [
6,
21]. The development of the UN Framework Convention on Climate Change (FCCC), the Kyoto Protocol, and the 2015 Paris agreement are the backbone of the existing global governance system [
10,
12]. Even though there is a strong global consensus that climatic changes must be addressed through the coordination of actors at different level [
10], measures addressing it in cities through existing governance arrangements are still far from what is required [
11,
37]. In summary, rather than climate action, for many cities around the globe, traditional matters, such as housing provision, sanitation, and waste disposal, are the more urgent areas for governance. Climate change remains ungoverned in cities [
14,
38], leaving a gap between policy rhetoric and action on the ground [
14,
32].
Especially in cities in developing countries, climate change governance lacks active engagement from urban actors [
39]. According to [
40], in most cities in developing countries, urban governments do not fully deliver their responsibilities due to various existing institutional arrangements, such as shortages of resources, inadequate capacity and weak frameworks for the engagement of actors, and weakening urban governance. Accordingly, many cities in Africa are more vulnerable to the impacts of climate change due to unplanned urbanization, lack of necessary risk-reducing infrastructure, services, and failures in urban governance [
41,
42]. Other challenges of climate change governance in African cities arise from lack of clarity in the assignment of responsibilities, lack of ownership over implementation, lack of resources, insufficient coordination, low political will, low private sector participation, and ineffective communication practices [
43,
44].
Ethiopia, an African country, faced the challenge of the governance of environmental issues [
45]. Environmental law is poorly enforced, and there is weak inter-sectorial coordination and stakeholder participation and low synergy among actors in initiating development programs [
46]. With low levels of environmental awareness, private companies lack adequate policies and management plans to discharge their corporate responsibility and safeguard the natural environment [
47]. Enforcement of environmental regulations is often constrained by a number of institutional and resource user-constituency factors, thereby ensuing numerous social and economic harms to the wider society and the economy at large [
48]. There are considerable discrepancies between those environmental commitments made by the country and the actual implementation [
47]. Even though the country is championing global sustainable development, the economic component of sustainable development is given more emphasis than its environmental component [
45]. Moreover, the country failed to meaningfully involve stakeholders at all levels of society, particularly at the local level [
49].
The notion of urban development practice in Ethiopia involves destroying the environment rather than protecting it [
50]. The climate resilience green economy (CRGE) document indicates that under current practices, greenhouse gas emission will more than double from 150 Mt CO
2e in 2010 to 400 Mt CO
2e in 2030, which indicates an increase of 250 Mt CO
2e [
51]. Out of this amount, about 42% of the increase or 105 Mt CO
2e is expected to be from urban areas (transportation, building, wastes, and industries) [
52]. If no further action is taken, GHG emission in the cities will increase by six-fold from 20 Mt CO
2e in 2011 to 125 Mt CO
2e by 2030 [
52]. Addis Ababa, the capital city of Ethiopia, has experienced a rapid rate of population growth and unprecedented spatial expansion (3.2% per year). As a result, the ecosystem services of the city are affected haphazardly [
53]. More than 35% of the solid waste generated by the city is not collected [
40]. The air quality in the city is affected by emissions from transport, dust from traffic roads, discharge from industrial activities, construction operations, and other overall land-use practices. According to [
54], the mean value of total suspended particulate matter (TSP) was about 195 μg/m
3, which is above the WHO safe guideline value (120 μg/m
3). From the total number of vehicles registered in the country, Addis Ababa has about 70% of them, and most of the vehicles in the city are older than 15 years and consume large amounts of fuel. The emission of pollutants from these vehicles causes environmental risk in Addis Ababa [
55].
Because of the increase in population, the Urban Heat Island phenomenon also became a feature of Addis Ababa [
56,
57]. The city is more exposed to heat waves, drought, and severe floods [
58,
59,
60]. Looking at the future, the city’s, urban heat island exhibits a clear upward trend [
57,
61]. Addis Ababa Green House Gas Inventory results in 2016 show that transport and waste sector emissions grew by six- and two-fold, respectively, as compared to the results in 2012. In addition, the emissions increased from 1.17 to 2.9 t per capita from 2012 to 2016 [
62]. Going forward, the maximum and minimum temperatures in Addis Ababa have shown increasing value. In addition, an overall increase in rainfall variability will be expected [
56,
57].
Moreover, although a lot of attention is being given to the green areas as a part of the city’s development plan, the real practice is the opposite. The threshold value of minimum green space per capita has been defined by the World Health Organization as 9 m
2, while Addis Ababa attains only 0.4 m
2 per capita. The disappearance of green space accounts for 40% of the flooding and landslides in the city and the recurrence of flooding is already costing ETB 0.21 million per event and estimated to be USD 6800 per year for emergency assistance at the city administration level [
40]. The vulnerability to flooding is more aggravated due to a poor drainage system and rapid informal housing development, and the cause of the increase in peak flow of flood is due to climate change and urbanization [
63]. Addis Ababa is vulnerable to climate change impacts and the combination of climate change and development pressures are expected to aggravate the current situation [
59].
Based on the environmental policy of the country, the Addis Ababa city administration has adopted different environmental policies, strategies, proclamations, and regulations to manage the environment in general and climate change in particular. The city administration started to implement Climate Resilience Green growth and integrated climate change response strategy to minimize GHG emissions and reduce the vulnerability of the city. Even though the city government has tried to manage climate change, there still is a state-dominant governing system in the city. The powers vested in government organs for making decisions on environmental issues is for administration organs at various levels rather than the environment departments [
64]. Institutional and legal frameworks that share responsibilities and accountabilities between the government, the private sector, and civil society organizations are not clearly defined [
45]. Policies and strategies have been initiated; however, there are still gaps that need to be addressed, such as a lack of horizontal and vertical coordination between sectors to manage climate-sensitive resources; the poor capacity of local governments, sub-cities, and Woredas; lack of awareness on existing policies and regulations; shortage of skilled manpower; shortage of finances; accountability; and a lack of clear roles and responsibilities of varies ministries, agencies, authorities, and offices [
40]. The participation of communities, NGOs, CBOs, and affected stakeholders is limited. Decentralization, private–public partnership, transparency, and accountability were not well implemented in the city [
40]. The major governance challenge in the city is implementing the intended plans [
65].
Several researchers, such as [
56], have investigate the trend of climate change with water shortage; [
59] conducted a climate-change-induced risk analysis of Addis Ababa city. The flood risk and vulnerability of Addis Ababa city due to climate change was conducted by [
63], and assessment of present and projected climate change in Addis Ababa was analysed by [
61]. Using a GIS-based method, the quantification and mapping of climate change and vulnerability hotspots in Addis Ababa city was conducted by [
66]. Climate-change-induced heat wave hazards in Dar es Salaam and Addis Ababa were evaluated by [
67]. Vulnerability of the city to climate change [
66] and air pollution through vehicle emission are the major problems in the city [
55]. All of the above studies have focused on the analyses of climate change scenarios, impacts, and vulnerabilities of the urban systems in Addis Ababa, but thus far, there has been no attempt made to integrate actors to respond to climate change.
Additionally, a study conducted by [
14] shows that the urban climate governance literature is still dominated by studies and scholars from the global north, with more than 86% being predominantly in North America and Europe. Despite the rapid growth in the urban climate governance literature, the knowledge from cities in the developing countries is still piecemeal. Some studies conducted in cities of developing countries include: governance framework to mitigate climate change in India conducted by [
68]; the implications for urban climate change governance in West Africa studied by [
69]; pathways to international cooperation on climate governance in China studied by [
70]; cities and climate change mitigation in three Asian cities Kolkata, India Palembang, Indonesia, Johor Bahru, studied by [
71]; the urban governance of climate change adaptation in least-developed African countries studied by [
72]; and urban climate change governance within centralized governments in Egyptian cities studied by [
73].
Therefore, it is important to ask about what climate change governance looks like in Addis Ababa, one of the cities of developing countries? To give a concrete answer for this question, examining the existing practice and conducting empirical scientific research is a necessity. In this regard, several global scientific research works [
1,
6,
7,
8,
15,
34,
74] have been conducted. However, those studies focused on qualitative comparative analysis in the developed cities and failed to examine quantitatively in developing cities. Studies on cities in developing countries conducted by [
30,
43,
68,
71,
72,
73] also used only qualitative analysis methods by using secondary sources. Therefore, this research is initiated to explore the practice of climate change governance in Addis Ababa City. The coordination of different tiers of government, vertically (federal, city, sub-city, and Woreda level) and horizontally (government, private sectors, and civil societies) are crucial to minimizing the current climate change in the city. Hence, the main objective of the study was to explore climate change governance practice in the city of Addis Ababa.
