Climate Change Policy Coherence across Policies, Plans, and Strategies in Pakistan—Implications for the China–Pakistan Economic Corridor Plan

Climate Change (CC) adaptation and mitigation policy coherence (PC) across sectors is essential to effectively address CC challenges and support synergies. Pakistan is highly vulnerable to CC. In this paper, the extent to which Pakistan’s national and provincial water, agriculture, and energy sector policies, development plans and strategies are aligned in a CC policy coherent manner is established. In this context, a qualitative content document analysis with associated scoring is used to assess government documents. Furthermore, implications of the China–Pakistan Economic Corridor Initiative (CPEC; 2017–2030), the biggest infrastructure investment program ever in Pakistan, are discussed. An important result is that sectoral policies are found to have different degrees of PC. Better coherence is found at federal than at provincial levels. Furthermore, CC policies are found to be more coherently addressed in water and agriculture policies than in energy policies. It is suggested that to achieve higher levels of CC PC, federal and provincial governments should establish mechanisms of intergovernmental consultation for policy-making and cross-sectoral planning, especially in the energy sector. Our findings can help the Government of Pakistan to transform CPEC into a model green Belt and Road Initiative (BRI) in the region. In this context, there are important implications with regards to e.g., reducing coal-based energy projects and environmentally damaging infrastructure activities in sensitive ecosystems. With this paper, the authors want to raise awareness of the key importance of CC PC, particular in context of the BRI. Many countries participating in the initiative have carbon reduction targets in place.


Introduction
Pakistan is highly vulnerable to climate change (CC) (Malik et al. 2012), which is threatening the country's water, food, and energy security (GoP 2012b). The country has experienced numerous climate-related disasters in recent year (Mukhtar 2018), including floods, droughts, storms, avalanches, glacial lack outburst, and landslides (Ali and Kandhro 2015). This is said to have resulted in a damage of US$ 20B over the past two decades (Shaw 2015). In the 2010 floods alone, 20 million people and 1/5th of the country's geographical area were directly affected (GoP 2012a). Whilst improved agronomical and conservation practices as well as more efficient resource use can help adapting to CC (Hellin et al. 2014;Howden et al. 2007), to what the extent these can be implemented in a developing country like Pakistan is uncertain. Although Pakistan is contributing to <1% of the world's GHGs emissions (Mohydin 2019), it has been said to be the seventh most CC-affected country (Eckstein et al. 2018). In addition to socio-economic loss, Pakistan faces serious environmental problems and the cost of environmental degradation in 2015 was said to be 9% of GDP equivalent (up from 6% of GDP in 2006) (Bank 2006;GoP 2017b). However, the government is currently spending just 0.00028% of GDP on environmental protection, including CC mitigation and adaptation .
The China-Pakistan Economic Corridor (CPEC) is the biggest investment project in Pakistan ever, worth US $62B. There are likely to be numerous environmental and CC impacts associated with CPEC investment (Zubedi et al. 2018;Kouser et al. 2020), in particular in connection with coal-based energy projects and infrastructure development.
Pakistan intends to reduce its expected GHG emissions by up to 20% of (equivalent to 1603 MtCO 2 ) by 2030, subject to funding (GoP 2016; Hussain et al. 2019b). This amounts to US$ 40B at 2016 prices and climate adaptation costs are projected to be US$ 7-14B/annum (GoP 2016), while mitigation costs for Pakistan are ranging between US $8B and US $17B by 2050 (GoP and UNFCC 2011). The energy sector is the main contributor to GHG emissions (50%), followed by agriculture (39%), industrial processes (6%), and other activities (5%) (GoP 2010).
The agricultural sector of Pakistan contributes nearly 21% to its GDP and to over 43% to the livelihood of rural populations (GoP 2015a). Water availability has dropped from 5000 m 3 in 1951 to current levels of <1100 m 3 per person (GoP 2014). In the future, CC could significantly affect water availability and thus agriculture (Qureshi 2005; GoP 2012b).
CC adaptation and mitigation are cross-cutting issues and need to be dealt within an integrated manner (Birkmann and Von Teichman 2010), for example, through strategic environmental assessment (SEA) of policies, plans, and programs (Fischer 2007), and environmental impact assessment of projects (Jiricka-Purrer et al. 2018). To date, research has highlighted numerous CC planning challenges; for example, a lack of cross-sectoral (Rahman 2010) and coherent (Khan and Jan 2015) planning, as well as a lack of institutional coordination (Chaudhry 2017;Ahmed et al. 2020). CC policy coherence (PC) is an area, which has not yet been examined in Pakistan. In this context, there are particular concerns with regards to the CPEC.
The objectives of this paper are: (i) to establish the extent to which CC adaptation and mitigation are mainstreamed into water, agriculture, and energy sector policies, development strategies and plans, and in disaster risk management plans in Pakistan; (ii) to analyse coherence in these policies, strategies, and plans with regards to CC adaptation and mitigation; and (iii) to critically review the CPEC development plan in the light of the above.

Conceptual Framework
PC deals with compatibility across policies along the entire policy cycle, from policy objectives to impacts (Nilsson et al. 2012). It promotes synergies between and within different policies (Nilsson et al. 2012). Whilst there is no universally agreed definition of PC, it is said to lead to policy stability and reduced policy failure (Howlett and Rayner 2007). Policy incoherence causes coordination and implementation problems (Cohen et al. 2017) and leads to an inefficient usage of resources (Mallory 2016). Consistency within sector-specific policies and plans is a precondition of PC (Voyer et al. 2020). Internal PC refers to interactions between policy objectives within a single policy domain, and external PC means interaction of different policies (Nilsson et al. 2012). CC PC is about coherence between CC adaptation and mitigation within and across policy domains (Nilsson et al. 2012). Similarly, internal CC PC promotes synergies and co-benefits (Di Gregorio et al. 2017) and reduces negative interactions. External CC PC refers to mutually beneficial practices and trade-offs reduction between CC aims and non-CC objectives (Di Gregorio et al. 2017).
The concept of PC with regards to CC and sustainable development has been examined by various authors. For example, CC PC among water, energy, land, food, and climate policies was assessed by Papadopoulou et al. (2020). Kalaba et al. (2014) analyzed PC between CC, agriculture, forest, and energy polices for Zambia and (Scobie 2016) highlighted challenges for small island developing states. These were said to include inadequate political will, and lack of accountability among actors. Similarly, bureaucratic politics were found to undermine policy integration and CC PC in Indonesia (Di Gregorio et al. 2017). Ranabhat et al. (2018) suggested that a collaborative and multi-stakeholder approach was required for effective CC PC in Nepal. Benson and Lorenzoni (2017) studied PC and CC adaptation in flood risk management plans in the UK and (England et al. 2018) assessed CC adaptation and PC across sectoral polices in South Africa.
Pakistan is a signatory to the Sendai Framework for Disaster Risk Reduction 2015-2030(UN 2015, the Paris Agreement on CC (UNFCC 2015), and the sustainable development goals (SDGs). All of those stress the importance of PC. With regards to the SDGs, all members have "to pursue PC and an enabling environment for sustainable development at all levels and by all actors" (UN 2016). Pakistan's overarching National Climate Change Policy (NCCP) 2012 is committed to integrate CC and the environment into development policies (GoP 2012b). CC mainstreaming requires PC and the reduction of inconsistent policies, creating opportunities for synergies (Juhola and Westerhoff 2011).
Pakistan is facing challenges with regards to policy formation and execution that lead to a reduction of PC. First, stakeholder consultations have not been given due consideration in policy formation. Ghani (2014) suggested that consultation, deliberation, and debate among stakeholders are hindered by high decision-making bureaucrats in policy formation processes. Furthermore, the former governor of the State Bank of Pakistan stated that capacity of provincial ministries and departments was inadequate in preparing policy documents, due to lack of essential knowledge and competence (Husain 2013) and that "Inter-ministerial consultation is more hostile than cooperative in nature. Ministers feel personally offended if their policy documents are criticized by other ministers. Stakeholder consultation is superficial and views of stakeholders, if diverting from those preparing them, do not find any place in the revised documents" (Husain 2013, p.7).
Second, effective execution of a policy requires availability of adequate resources (Gerston 2010). In the case of Pakistan, due to financial constraints and capacity building issues, these resources are not utilized properly in policy development processes. Similarly, other factors explaining the lack of consistency include poor institutional coordination, corruption, and weak policy formulation and implementation processes (Sirajul 2015). Sectoral policies mention the adoption of integrated management (e.g., integrated water management) but fail to outline any implementation frameworks. Integrated water resources management cannot be executed due to national and provincial mandates on water resource management, and associated equitable dissemination of costs and benefits among stakeholders (Khan 2019). Finally, contradictory interests lead to policy incoherence (Siitonen 2016).
There are obvious inconsistencies, including e.g., the CPEC coal power projects that are not consistent with Pakistan's own green policies (Ebrahim 2020). The government's alternative energy policy (2019) commits to 30% of energy mix being from renewable sources by 2030 (GoP 2019a, b). It is within this context that subsequently an analysis of CC mitigation and adaptation coherence across sectoral and CC policies, development strategies, and plans is provided. Figure 1 shows major CPEC projects planned in Pakistan. CPEC projects are expected to result in an increase in GHG emission of 371 MtCO 2 by the year 2030 (Janjua et al. 2018). The energy sector will make up around 56% of Pakistan's total annual GHG emissions in 2030 (Janjua et al. 2018). Most energy projects of CPEC are coal-based with severe environmental and potentially social impacts (Bilgen 2016;Verma et al. 2017). Connected with CPEC, about 7000 trucks per day are expected to go through Northern Pakistan, resulting in emissions of carbon dioxide of up to 36.5 million tons (Qazilbash 2017).
The agriculture and energy sectors are key development areas of CPEC 2017-2030 (GoP 2017a) contributing significantly to GHG emissions. Energy sector emissions have increased by 117% since 2015 and those associated with agriculture have increased by 145% (GoP 2016). Water, energy, and food sectors are particularly vulnerable to CC (Hussain et al. 2019a). However, coordinated, cross-sectoral, and multiscale CC adaptation and mitigation planning has been missing (Rahman 2010).

Methodology
Qualitative document analysis (Altheide et al. 2008) and content analysis (Steve 2001) are the basis for the empirical research into PC underlying this paper. A scoring system based on the work of Le Gouais and Wach (2013) was used for establishing sector rankings, followed by a validation based on semi-structured interviews with experts and practitioners. Stages of the project underlying this paper include (i) establishment of criteria of document selection, (ii) identification of relevant documents, (iii) document analysis, (iv) validation, and last (v) finalization (Altheide et al. 2008). At stage (i), official government documents were considered from relevant ministries and departments of Federal and provincial governments of Punjab (PB), Sindh (SD), Khyber Pakhtunkhwa (KP), Baluchistan (BA), Gilgit-Baltistan (GB) region and the territory of Azad Jammu and Kashmir (AJK). Whilst Federal and provincial governments of PB, KP and GB had complete sets of policy documents across water, agriculture, energy, and CC policies, strategies, development plans, and programs (Table 1), in SD, BA, and AJK, only few such documents exist. Therefore, these were not considered.
The subsequent focus is on water, agriculture and energy policies, strategies and plans, disaster management plans, as well as on cross-sectoral linkages for mainstreaming CC. For collection of relevant policy documents, websites of federal ministries and provincial departments (stage ii) were used. In case, policy documents were not placed on websites, officials were asked (by phone and/or email) to provide them. Documents were then systematically analyzed (stage iii) with regards to: whether CC adaptation and mitigation were mentioned; how they were being addressed, i.e., whether they were mentioned as generic statements or in policy objectives, and/or with detailed plans, activities, implementation frameworks; and whether statements of CC adaptation and mitigation were consistent with other policy documents. A four-step content analysis approach was used for document analysis (Steve 2001). The PC assessment criteria are depicted in Table 2.
Selected policies, as well as development plans and programs were assessed with regards to the presence of five key subjects: (a) water, (b) agriculture, (c) energy, (d) water-agriculture-energy inter-sectoral alignment to adapt to and mitigate CC, and (e) CC adaptation and mitigation (see Table 3). When CC adaptation and mitigation were included was taken note of and the context in which they were found in was described. Words used in the analysis of each selected policy document include: • Flood and drought management, Analysis was conducted for documents from each of the selected provinces and territories, making crosscomparisons of sectors, development plans, strategies, and policies possible. Policy development dates were recorded. Furthermore, information obtained was used to guide expert  (Farooqui and Aftab 2018) interviews. Allocated scores range from 3 (full coherence) to 0 (no coherence). By calculating the average of two values (mean of means), we assessed the coherence of policies relative to one another within each province/territory (Table 4). For example, the coherence of the Federal's Water Policy (2018) in relation to its CC Policy (2012) is 2.3 (with an average coherence being 2 for Federal's Water Policy and 2.6 for its CC Policy). This average value meant that there was a partial PC score. Validation and finalization involved semi-structured interviews with experts that work across the various sectors. For this purpose, assessment results of Tables 3 and 4 were discussed with experts. To ensure confidentiality, no information is provided on the role of or relationship with interviewees. Interview records were coded according to sectoral themes and policy priority areas. Finally, the CPEC development plan was assessed in the light of the results on PC in other decision processes of Pakistan, based on the criteria shown in Table 2.

Water Sector Policies
National Water Policy aims at restoring and maintaining the health of the environment and water-related ecosystems. Associated planning principles include that environmental sustainability must be ensured, and EIA studies be carried out concurrently with project feasibility studies for water resources. Consistency with economic viability, social acceptability, and environmental sustainability also needs to be ensured. CC mitigation and adaptation assessment should be carried out "for sustainable water resource development and management" to address water, energy and food security, and climate-driven disasters. Although water is a national responsibility, agriculture and irrigation, environment and water-related sub-sectors are provincial subjects under the 18th constitutional amendment (GoP 2018b). KP and GB have still not developed their own policies for water management, with GB having adopted the National Water Policy, and KP having formulated a drinking Water Policy in 2015. This highlights the need for water resource conservation, and commits to "Measures [that] will be taken to identify, protect, develop, and conserve surface and ground water resources in line with Provisions of National Environmental Policy (NEP) 2005 and KP Environmental Act 2014." It is also stated that "Due consideration will be given to the adverse impacts of CC, vulnerability and fragility, in planning and development of  water supply scheme" (GoKP 2015). However, adaptation and mitigation measures for water resource management are not mentioned. PB's Water Policy states that "policy measures related to water resources applicable to PB in line with the NCCP 2012 [should] be adopted" but clear delivery mechanisms are missing. The policy recognizes adaptation but does not highlight CC mitigation measures and strategies. It is stated that adaption measures be worked out to mitigate impacts of CC. PB's Water Policy (2018) highlights environmental hazards and its EPA recognizes the environment as a policy objective, aiming to "ensure effective enforcement of regulations for managing the health of acquirers in collaboration with EPA." CC adaptation and mitigation mainstreaming are not detailed in any water sector policy.

Energy Sector Policies
Pakistan's energy sector contributes 51% to the country's total greenhouse gas emissions (Ashfaq 2017). Federal and provincial governments' energy policy documents mention the need for environmental protection but fail to consider CC adaptation and mitigation. The Federal Power Policy (2013) focuses on energy affordability, efficiency, financial viability (GoP 2013b), and the need of a green building code. However, it too fails to mention CC. The same is the case for the Power Generation Policy 2015, which does recognize environmental safeguards as one of the policy objectives, though (GoP 2015b).
None of the provincial policies consider CC. The PB Power Generation Policy includes environmental protection as a policy objective and states that all the "requirements as related to EIA and NEQS will be met" (GoPB 2009). Furthermore, the KP Hydropower Policy 2016 recognizes that "requirements laid down by KP EPA and rules and regulations thereunder relating to NEQS and EIA shall have to be met" (GoKP 2016a, b), but fails to address inter-provisional environmental problems. The Government of GB has not formulated their own policy for power generation. Rather, it has adopted the Federal Power Generation Policy 2015.

Agriculture Sector Policies
The agriculture sector in Pakistan accounts for 43% of total national greenhouse gas emissions (GoPB 2018b). The National Food Security Policy states that the sector needs to "flexibly adapt into CC and be resilient enough to quickly recover from shocks and emergencies" (GoP 2018a, p. 25). Furthermore, whilst it recognizes policy measures for environmental biodiversity conservation and development of climate smart crops, it fails to highlight CC. Whilst CC adaptation measures are mentioned in PB's Agriculture Policy 2018, KP's Agriculture Policy mentions both, CC adaptation and mitigation measures and strategies for water, agriculture, and energy sectors (GoKP 2013). The GB Agriculture Sector Policy finally is quiet about CC (GoGB 2018b).

CC Policies
Pakistan's first NCCP 2012 recognized the need to integrate CC adaptation and mitigation measures into sector planning, including water, agriculture, energy, transport, forestry, vulnerable ecosystems, and industrial sectors. It called for a development of plans at federal and provincial levels for effective NCCP implementation (GoP 2012b). The policy aims at integrating CCP with other inter-related national policies "to ensure water security, food security, and energy security of the country in the face of the challenges posed by CC" (GoP 2012b). The NCCP implementation framework (2014-2030) provides a mechanism to mainstream CC concerns into national planning to promote climate-compatible development at federal and provincial levels (GoP 2013a). However, neither NCCP 2012, nor its implementation framework identify a mechanism to evaluate CC adaptation and mitigation progress. Similarly, provisional governments have no approved CCPs yet, while draft CCPs are failing to Policy documents offer attention to water-agriculture-energy inter-sector alignment to adapt to and mitigate CC, activities, strategies, plans, and implementation framework.

PB's CC policy draft (2017) recognized the need to be in line with the NCCP (2012), its implementation framework (2013) and PB's Growth Strategy (2018) (GoPB 2018c). The policy objective is to "integrate climatecompatible development paradigm through climate resilient, low carbon, and water-energy-food nexus-related measures into key relevant sectors policies, strategies, and plan" (GoPB 2017). However, it fails to mention coordination mechanisms with cross sector policies. Similarly, KP Province's CCP (2016) aims to "Integrate adaptation and mitigation measures into key relevant sectors policies, strategies, and plans" (GoKP 2016a; b) to "ensure water, food and energy security for KP province in the face of a CC". In addition to CC adaptation for agriculture, water resources, forestry, and disaster preparedness, the KP CCP also recognizes CC mitigation measures for energy, transport, waste, industries, and urban planning (GoKP 2016a, b). The need to work in line with NCCP is acknowledged, but no coordination mechanisms with sector policies are mentioned. Similarly, the GB CC Strategy and Action Plan (2017) recognize the hydropower potential of the region, and CC impacts on glaciers, agriculture, and energy sectors (GoGB 2017b). Policy objectives, strategies, and actions to adopt and mitigate CC are acknowledged, but no implementation coordination mechanisms with other sectors are mentioned.

Development Plans and Strategies
Federal and PB's development plans consider CC adaptation and mitigation measures, and introduce projects to address CC along with environmental protection. Similarly, the development plans of GB (GoGB 2017a) and KP (GoKP 2018a) recognize some schemes and measures for flood and environmental management but fail to integrate CC. The National Sustainable Development Strategy takes into consideration the three pillars of sustainable development: economic, social and environmental, and recognizes 17 SDGs with strategic objectives and targets, and commits to integrating CC and the environment into national and provincial sectoral polices, plans, and strategies (GoP 2017b). PB's Growth Strategy 2023 integrates the environment and CC and recognizes SDG-13 (Climate Action), which is about "[taking] urgent action to combat CC and its impacts" and SDG-12 "ensuring sustainable consumption and production patterns" structural and non-structural adaptation and mitigation measures, but lacks an implementation framework (GoPB 2019). Similarly, the KP development strategy considers CC adaptation and mitigation measures, environmental security, and the mainstreaming of environmentally friendly strategies to reduce environmental hazards (GoKP 2014; 2019b).
The sustainable development strategy of GB recognizes flood disasters and aims at ensuring the environment is considered in planning. Furthermore, it commits to conducting SEA in the water and energy sectors, but fails to explicitly consider CC (GoP and IUCN 2003).

Disaster [Risk] Management Plans (DMPs)
The Federal Government's DMP 2012-2022 (GoP 2012c), PB's DMP 2008(GoPB 2008), and GB's DMP 2008(GoGB 2008 consider CC and the environment, and recognize structural and non-structural adaptation and mitigation measures for CC, DRR, and environmental protection. KP has not developed a DMP yet. However, there are monsoon contingency plans (GoKP 2017;2019a), focusing on flood disasters. Environment, CC structural and non-structural adaptation, and mitigation measures and DRR strategies are mentioned for vulnerable sectors (not including the energy sector).

PC across Policies, Plans and Strategies at Federal and Provincial Levels
PC is not explicitly addressed in most policy documents. The Federal water policy considers NEP 2005 and NCCP 2012, but lacks coherence with agriculture and energy sector policies (GoP 2018b). Similarly, PB's water policy highlights the need to adopt the national water policy measures and NCCP, but fails to establish working coordination with energy sector policies. Likewise, the KP drinking water policy highlights the need to adopt national drinking water policy and to align this with NEP 2005, but fails to mention policy coordination with CC, agriculture, and energy sector policies.
The Federal national food security policy states that "there is a need to implement NEP 2005 and NCCP 2012 in letter and spirit" (GoP 2018a, p.17, 19), but fails to consider policy coordination with energy sector policies. Likewise, the agriculture policies of PB and KP fail to state coordination with sectoral policies of water, energy, and CC policy. Also, the KP agriculture policy does not mention environmental policy. Similarly, although the agriculture sector policy of GB establishes a need to harmonize sectoral policies, it fails to mention water and energy, environmental, CC policies, and coherence mechanisms.
The Federal and PB's power sector policies fail to mention coordination with policies of water, agriculture, CC, and environmental sectors. PB's CC policy recognizes the NCCP and national energy policy, and is committed to a centralized provincial water policy. It also asks for PB's power generation policy to be updated (GoPB 2017). However, it fails to consider coordination with agriculture policy. Similarly, the KP CC policy highlights the need to work in line with NCCP (GoKP 2016a, b), but fails to consider coordination with water, agriculture, and energy policies. The GB CC strategy recognizes the need to develop an energy policy, highlights NEP, and follows NCCP guidelines (GoGB 2017b). However, sectoral policies of water, agriculture, and energy are not considered. Similarly, federal and provincial governments' development plans fail to consider environmental and CC policies.
PB's Growth Strategy (GoPB 2019) does not consider CC policy while the sustainable development strategy of KP province fails to mention agriculture policy (GoKP 2019b). Similarly, the GB strategy for sustainable development 2003 fails to mention CC policy. Furthermore, there is no coordination with water, agriculture, and energy sector policies. The DMP of federal and provincial governments, of PB, GB, and KP fail to mention environmental, water, food and agriculture, as well as energy sectors policies.

PC across CPEC and Sectoral Policies, Development Plans, and Strategies
The federal and provincial governments' agriculture policies and development strategies consider the CPEC plan as an opportunity. For example, PB's agriculture policy recognizes that CPEC connectivity enhances competitiveness with global and domestic markets but fails to mention coordination and implementation mechanisms. Similarly, the national food security policy recognizes the establishment of agricultural economic zones along CPEC routes, enhancing agricultural economic cooperation under CPEC, but is missing a policy coordination mechanism.
The water and energy sector policies miss integration with the CPEC plan 2017-2030. Likewise, Federal and KP development plans recognize development projects under the CPEC portfolio. The CPEC plan recognizes opportunities and possible implementation challenges, highlighting that industrialization and urbanization in Pakistan will speed up, whilst also acknowledging associated environmental degradation (Alam et al. 2007) and additional CC emissions.
The CPEC plan 2017-2030, whilst neither mentioning CC policies, nor CC adaptation and mitigation measures, highlights the need to optimize sourcing and technology development of the coal industry, the promotion of river planning for hydropower, wind, solar-energy development, and water efficient technology for irrigation. Moreover, the plan also recognizes the need for social environment safeguards for CPEC projects.
For industrial cooperation, the CPEC plan highlights the need to promote environmentally friendly processes without referring to NEP 2005 and the national operational strategy 2006 for clean development mechanisms. Similarly, although it highlights measures in sectoral policies, it does not mention sectoral polices of water, agriculture, and energy, DRR and CC PC mechanisms.
Our analysis indicates that Federal, PB and GB water and agriculture policies were most coherent (Table 3). For example, the percent coherence score of the Federal Water Policy (2018) is 66.66% (see Table 3). The results of coherence analysis at federal and provincial levels across sectoral policies, CC policies, development strategies and plans, and disaster management plans are shown in Table 4 and Figs. 2-4.
With regards to PC on CC, the maximum possible coherence score would be 126. CC adaptation and mitigation mainstreaming in sectoral policies and other selected documents remains partial, with no scores of 3 for any Federal and Provincial policies being achieved. The analysis also indicates that energy sector policies at federal and provincial levels have the lowest PC scores to address CC.
Our analysis indicates that Federal water and agriculture sector policies were the most coherent documents, followed by PB, KP, and GB region. These coherence scores across policies are established by calculating the percent coherence value of each policy document (Table 4). For example, the percent coherence score of Federal's Water Policy (2018) across policies is 68.16% (see Table 4).

Discussion
CC (Janjua et al. 2018;Kouser et al. 2020) as well as environmental impacts (e.g., air and water quality) are the main challenges of Chinese FDI in Pakistan (Huang et al. 2017). Most energy projects of CPEC are coal-based (Faisal Mehmood et al. 2019). Northern Pakistan, a gateway to CPEC, has highly vulnerable and sensitive ecosystems (Dadwal and Purushothaman 2017) that are threatened, in particular by CPEC-funded highways (Nabi et al. 2018). Glaciers in Northern Pakistan cover an area of 5218 km 2 (Gilany and Iqbal 2016). These glaciers are regulating local and global climate functions (Kääb et al. 2012). Glaciers in the region are currently receding rapidly (Gilany and Iqbal 2016) at a rate of 0.66 ± 0.09 m per year (Kääb et al. 2012). CPEC is likely to accelerate melting of these glaciers (Nabi et al. 2018).
Generally speaking, CPEC is expected to lead to a transition from rural to urban economies. Currently, water demands of urban lifestyles are much higher than those of rural settings, and CPEC projects are predicted to lead to an increased water demand for development that could exceed 2467 mm 3 by 2025 and 4317 mm 3 by 2050 (Amir and Habib 2015).
Pakistan's energy sector contributes significantly to GHG emissions. It is projected that GHG emissions (in million tons CO 2 eq.) will increase from 347 to 4621 in 2050 under a Business as Usual scenario (GoP and UNFCC 2011), and the energy sector will contribute almost 60% by the middle of the century ). This is a challenge to CPEC development and could partly be addressed through CC mainstreaming in energy policies and PC, which is currently missing. The urbanization and industrialization agendas under the CPEC plan portfolio further enhance environmental degradation and CC impacts. CC PC is essential for synergies and sustainable development (Di Gregorio et al. 2017) and the CPEC plan fails to consider environmental sustainability and CC PC, mainly because it fails to highlight ways of mitigating CC and environmental impacts. There is a multidimensional interrelationship linkage among development, environmental degradation, and climate-driven disaster events (Gore and Fischer 2014). Therefore, challenges from the CPEC plan include CC and interlinked environmental degradation, as well as climate-driven disasters.
Whilst the CPEC plan recognizes the multidimensional aspects connected with the economic cooperation with China (and with other regional countries), it fails to establish PC mechanisms to deal with environmental and CC global issues. However, the country has legal instruments for implementation of environmental and CC policies, including the Federal and provincial environmental acts and Pakistan's   Fig. 3 Overview of coherence score of policies, plans, and strategies of Fereral and Provincial governments CC Act 2017. It means that the country is progressing with regards to its institutional and legal framework but lacks CC PC. In this context, SEA, a tool to promote CC PC and CC mainstreaming of policies, plans, and programs (Barker and Fischer 2003) is included in provincial environmental acts only. CC PC is challenging for Pakistan in particular when considering that currently the government is spending just 0.00028% of GDP on environmental protection, including CC mitigation and adaptation . The Federal Power Policy (2013) plans for coal-based energy production of 6000-7000 MW, and also mentions medium and long-term plans for hydro, solar, and wind projects, including 2726 MW of wind electricity, 341 MW of solar energy, and the possibility for hydropower projects of Bunji (7100 MW potential) and Diamer-Bhasha (4500 MW potential) (GoP 2013b). The Diamer-Bhasha dam is meant to also mitigate floods (APP 2020) and provide low-cost and clean electricity (Gul 2020). Federal government has set a target of 30% of renewable energy generation by 2030 (GoP 2019a, b), in line with an international obligation to reduce GHG emissions. The federal power policy 2013 failed to establish targets for renewable energy generation. Similarly, PB's Power Policy and KP's Hydropower Policy (2016) recognize the hydro potential and aim at generating hydropower of 600 MW at Federal (GoPB 2009) and 30,000 MW (GoKP 2016a, b) at provincial levels. Pakistan has a hydropower potential of 100,000 MW (Qazilbash 2015) and whilst the government recognizes this potential there is currently no coherent mechanism for implementation.
Pakistan has been portrayed as a country with low CC adaptive capacity (Abid et al. 2015). And whilst it is contributing only 0.8% of the total global GHG budget (Hussain et al. 2018), it has committed to reduce carbon emissions by 20% as part of 'Intended Nationally Determined Contributions' (GoP 2016). To address CC, Pakistan has CC policies at federal and provincial levels. The Federal NCCP (2012) highlights CC mitigation measures for sectors such as energy, forestry, agriculture, and livestock. The main CC mitigation targets focus on GHGs emissions reduction in energy and agriculture sectors, with special attention given to energy efficiency, while other highlighted mitigation areas include changes to the energy mix, renewable energy resource development, and increased share of nuclear and hydroelectric power. The country also recognizes that if it wants to tap into its coal resources of 185 billion tons, clean coal technologies will be needed (GoP 2012b). Green fiscal reforms in the energy and water sectors to reduce carbon emissions are also anticipated.
In the PB CC Policy 2017 a "Triple Win" strategy is advocated where the need for carbon compatible and  (2017) recognize the need to mainstream CC mitigation and adaptation, highlighting strategies, objectives and action plans for thematic areas. These include e.g., infrastructure resilience, CC mitigation and adaptation for water, and power sectors. It highlights that current energy demand of GB is more than 500 MW while the hydropower generation potential in GB is more than 40,000 MW (GoGB 2017b).
Pakistan is ranked 7th internationally regarding coal reserves  with about 186 billion tons of coal (Ghaznavi et al. 2016) resources in all provinces . Coal is currently the most significant and cost-effective energy source in Pakistan (Satti et al. 2014). Thar coal alone has the potential of 100,000-MW electricity generation (Tribune 2020). KP province and GB have about 76% of country's total hydro generation potential of 45,861 MW, while PB and AK have a potential of 7291 and 6450 MW, respectively (Wajsal 2015). However, 89% of this potential still remains unexploited. In addition to the wind energy potential of more than 300,000 MW (Wajsal 2015), Pakistan has 2.9 million MW of solar-energy potential (Tribune 2017, Wajsal 2015). About 40,000 remote villages will receive solar-energy-based electricity (Khan et al. 2014). Solar energy is the best renewable energy option for Pakistan in terms of maintenance cost, operations, and life span (Irfan et al. 2019). The country receives solar radiation of 1500-2500 h annually (Kiani 2019) and Balochistan alone has an annual mean sunshine duration of 8-8.5 h per day (Kiani 2019), the highest solar potential in the world.
With regards to PC around CC adaptation and mitigation, Federal Government has the most coherent set of policy documents in place with a total coherence score of 87.32, followed by PB (65.64), GB (58.1), and then KP (51.1) (see Table 4). At Federal level, the National Sustainable development Strategy 2017 has the highest PC score (14.77), followed by NCCP 2012 (13.86) and DMP 2012DMP -2022. The National Water Policy 2018, and National Food Policy Security Policy 2018, and Development Plan have a PC score of 12.27. The Energy Policy has the lowest PC score (9.21).
It is important that in Pakistan, entire policy documents are simply copied. For example, GB has adopted federal water and energy sector policies. The problem with simply using federal policy is that they were not developed in consultation with the relevant stakeholders. Such adopted policies are bound to fail to establish coherence with other sector policies. Dependency on policies developed by external stakeholders reduces opportunities for consultation across relevant departments and ministries, meaning that opportunities for greater coherence are being missed. Policies remaining in draft form for a long time have been found to reduce PC throughout the world. Policy evaluation and revision are key for effective PC development (Picciotto 2005). A common issue of developing countries is infrequent and delayed policy revisions, as well as missing designated specific review dates. Most of the sectoral policies have rarely been revised. For example, Tanzania's national water policy was first developed in 1991 and revised in 2002, while national agriculture policy was first produced in 2013 (England et al. 2018). In case of Pakistan's policy documents, they are also rarely updated and approved. Water sector policy formation and approval processes are very slow in Pakistan. The country's first national water policy was approved as recently as 2018 (after many years of having draft status (Khalid 2017), while Malawi's, Tanzania's, and Zambia's National Water Policies are from 2005, 2002, and 1994, respectively.

Conclusions
Pakistan's national sustainable development strategy (2017) recognizes the necessity to enhance PC as a strategic objective. However, this paper has shown that only some policies, strategies, and plans are being coordinated with other sectoral policies and plans. An effective mechanism of maintaining coherence is missing in Pakistan. CC adaptation and mitigation is covered in all water and agriculture sector policies but not in energy sector policies. This has implications for the CPEC Plan (2017-2030), which has remained a standalone document as it does not consider the country's CC policies, sectoral policies, and PCPC mechanisms. When a mega development plan of power generation and infrastructure development projects with expected significant environmental impacts is being executed under the CPEC, there should be coherence with CC, water, agriculture and energy sector policies and plans. Provincial draft CC policies, and the GB regional strategy for sustainable development 2003 need revisions with a PC approach in mind. After the 18th constitutional amendment, environment and disaster management have become provincial matters. Therefore, NEP 2005 and Provincial DRR plans of 2008 and of GB region need to be updated and revised. Janetschek et al. (2020) suggested that active engagement of stakeholders is essential for effective PC for development and mutual benefits in national policies. This is currently missing in Pakistan (Ghani 2014;Husain 2013). There is a need to conduct effective stakeholder consultation in policy formation and for existing sectoral policies and CPEC plan revisions to ensure CC mainstreaming and PC for development. It is recommended that CC and environmental concerns need to be integrated into energy sector policies as most of the power generation projects under CPEC are coal-based and are likely to contribute significantly to greenhouse gas emissions. The government should establish an inter-ministerial committee or a similar body for devising mechanisms at federal and provincial levels for PC to address CC and environmental impacts. In general terms, in Pakistan the environment and CC remain subject to a supply rather than a demand-driven agenda. The CPEC act as a bridge for BRI development. In January 2021, 140 countries of Asia, Europe, Africa, and beyond had joined the BRI initiative (Nedopil 2021). CC and environmental degradation are substantial challenges of BRI development (Desheng et al. 2018;Fang et al. 2021;Deng and Du 2020). CC PC has important implications for countries along the BRI with regards carbon reduction targets, and with regards to achieving coordinated socioeconomic and ecological development.
