Biodiversity Conservation and Management in the Hindu Kush Himalayan Region: Are Transboundary Landscapes a Promising Solution?

Maintaining the health of biodiversity and ecosystem services is becoming an increasingly important concern for the global community. The biodiversity-rich Hindu Kush Himalayan (HKH) region provides a myriad of ecosystem services but is experiencing rapid biodiversity loss and habitat degradation under the influence of climate change and other drivers of change. Biodiversity and ecosystem services often transcend geopolitical boundaries, and biodiversity management requires efforts that span larger landscapes. Globally, a landscape approach to management is recognized for its ability to reconcile objectives of biodiversity conservation and sustainable development. In order to institutionalize the landscape approach to enhance ecological integrity and sociocultural resilience in the region, the International Centre for Integrated Mountain Development, with its partners in 8 countries, pioneered transboundary landscape (TBL) conservation and development initiatives between 2007 and 2019. This article reviews processes, outputs, and outcomes of the 4 TBLs designated and operationalized in the HKH region and distills key learning from an in-depth external evaluation of the Kailash Sacred Landscape initiative. The article draws the inference that transboundary cooperation as a collaborative process is both dynamic and evolutionary. Evidence, collaborations, inclusive partnerships, ownership, cross-border learning, joint policy influencing, and systemic thinking are key ingredients for any transboundary cooperation. TBLs have the potential to galvanize regional cooperation processes that help individual countries collectively address biodiversity conservation and development-related milestones, targets, and impacts.


Introduction
Biodiversity and ecosystem services often transcend geopolitical boundaries (López-Hoffman et al 2010;Erg et al 2012). Several biodiversity conservation and management issues, such as wildlife trade, forest fires, migration of animals, watershed restoration, corridor and connectivity development, and transboundary protected area management, are transnational in nature (Liu et al 2007). Since many ecological, evolutionary, and social processes become evident at the landscape level, biodiversity management requires efforts that span larger landscapes (Baldwin et al 2018). The transboundary landscape (TBL) concept stands on the premise that ecosystem services flow beyond the administrative boundaries of any one nation and that the risk of biodiversity degradation can be reduced through common and coordinated cross-border measures (Hamilton and McMillan 2004;Sayer et al 2013).
Globally, landscape management has gained attention as being vital to both long-term biodiversity management and equitable development (Reed et al 2016). It bridges boundaries across different discourses, disciplines, and values (ICIMOD 2019a) and allows biodiversity conservation measures to consider wider societal issues across political regimes (Dallimer and Strange 2015). Resource users and managers have adopted integrated landscape approaches to sustainably reconcile objectives of biodiversity conservation and sustainable development (Frost et al 2006), build the resilience of ecosystems spread across 2 or more nations (Hamilton 2008), and address wider social, economic, and environmental objectives (Locke 2011).
As an area of high biodiversity richness, the Hindu Kush Himalayan (HKH) region hosts 4 of 36 global biodiversity hotspots, 60 of the 200 global ecoregions, and 330 Important Bird and Biodiversity Areas . This biodiversity provides a multitude of ecosystem services, namely food, fodder, timber, medicinal plants, genetic resources, freshwater and clean air, pollination, seed dispersal, disease regulation, hazard and erosion control, flood regulation, water purification, knowledge systems, recreation services, and provision of habitat, nutrient cycling and species evolution (Xu et al 2019). These benefit 1.9 billion people in the mountains and the downstream areas of the HKH region (Wester et al 2019).
The region is experiencing rapid biodiversity loss and habitat degradation . Mega-investments, such as the Belt and Road Initiative (Ascensão et al 2018), hydropower development, and regional waterways for economic development and food security (Rasul et al 2019) present new challenges to efforts aimed at conserving the region's biodiversity resources. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) highlights that while protected area coverage in the Asia Pacific region has increased substantially, most protected areas do not effectively accommodate important biodiversity hotspots affected by economic development (IPBES 2018). In addition, the economic transformation in the Asia Pacific region will have high environmental costs, including further degradation and loss of biodiversity.
For the HKH region, sustaining the flow of ecosystem services into the future is a key challenge, as biodiverse habitats are rapidly degrading and the existing biodiversity protection mechanisms are inadequate (Xu et al 2019). Social challenges, such as poverty, inequity, cultural degradation, and vulnerable livelihoods, add to the complexity of effective biodiversity management (Gioli et al 2019). Natural resources policies and governance are not adequately decentralized (Pasakhala et al 2017) and do not acknowledge transboundary cooperation as a mechanism enabling governance for long-term biodiversity conservation (Xu et al 2019). Moreover, conservation and development strategies often conflict between sectors .
Despite many positive global actions by parties and stakeholders to achieve the Aichi Targets of the Convention on Biological Diversity, countries in the HKH region have yet to adequately consider the cross-border mechanisms and networks related to social, ecological, and economic issues that are linked to biodiversity use and conservation (Sharma et al 2007). In order to institutionalize the concept of longterm transboundary cooperation to enhance ecological integrity and sociocultural resilience in the region, as well as to help countries in the HKH link their national commitments to global conservation goals, the International Centre for Integrated Mountain Development (ICIMOD) partnered with its 8 member countries to conceptualize and operationalize the concept of trans-Himalayan transect and embedded landscapes (Sharma and Chettri 2005). In this article, we review the processes, outputs, and outcomes of the 4 TBLs designated and operationalized in the HKH region. We consider whether TBLs can be a promising solution to facilitate collaboration for biodiversity conservation and management in a region that is geopolitically sensitive and has a rich biodiversity, a poor rural economy, and high climate change risks .

Methodology
The article is based on a review of key procedures of conceptualizing, initiating, executing, and adapting TBL initiatives in 4 landscapes ( Figure 1) to demonstrate whether the TBLs are a promising solution for facilitating effective biodiversity conservation and management in the region. The state-of-art review is based on analysis of project reports from HimalDoc (https://lib.icimod.org) and published resources. The review summarizes a process of learning, unlearning, and relearning regional cooperation for biodiversity conservation and management in the HKH region between 2007 and 2019. We begin by outlining the TBL and the trans-Himalayan transect conceptual framework that set the rationale and foundation for TBLs. This helped to define the scope and significance of TBLs in prompting an effective science-practice-policy connect for biodiversity conservation and management. Next, we elaborate on the 4 TBLs that were implemented to facilitate regional cooperation among countries to strengthen conservation and long-term monitoring outcomes. We then elaborate the operationalization and evaluation of a flagship landscape initiative-the Kailash Sacred Landscape Conservation and Development Initiative (KSLCDI)-a TBL initiative to secure dedicated funding for full-fledged implementation (ICIMOD 2009). Finally, we reflect on the adaptation of actions in other landscapes as a part of lessons learned from KSLCDI. We conclude the article by discussing the key enabling features of the TBLs that facilitate regional cooperation for biodiversity conservation and management in countries with contiguous biodiversity resources as well as The 4-step process used in this article to review the transboundary landscapes.
common cross-border biodiversity management challenges and opportunities.

Results and discussion
The conceptual framework A conceptual framework of trans-Himalayan transects and TBLs ( Figure 2) was codesigned by ICIMOD and its partners in Afghanistan, Bhutan, China, India, Myanmar, Nepal, and Pakistan (ICIMOD 2008). It arose from the realization that combating the threats to biodiversity and ecosystem services is a global issue requiring strong interfaces across science, practice, policy, and societies at different scales . The essence was to carve an effective pathway for regional cooperation, capturing milestones and targets set by global multilateral instruments . The framework elaborated on the 4 fundamental principles of promoting integrated and participatory approaches in ecosystem management, integrating multi-stakeholders priorities, promoting regional acceptance of common frameworks between nations, and collectively contributing to global policy processes (Shakya et al 2012). It served as a holistic framework to address the biodiversity data gap in the region as indicated by the fourth report of the Intergovernmental Panel on Climate Change (IPCC 2007), and to simultaneously tackle environmental, socioeconomic, and political challenges for biodiversity conservation and management beyond the administrative and management boundary of one nation (Bennett et al 2015).

Orchestrating 4 transboundary landscapes
The TBLs were designated to serve as a prospective geographic unit to operationalize the framework described earlier. They were conceptualized as entry points to facilitate long-term regional cooperation for biodiversity conservation and monitoring (Chettri et al 2009) and to trigger ecological and socioeconomic resilience (Shakya et al 2012). In order to be representative of the entire HKH region, 6 TBLs were identified, but operationalized in 4 landscapes (see Figure 2; Table 1). The rationale was to select a landscape where 2 or more countries could participate and where countries have some level of ecosystem, economic, and sociocultural connection (Sharma and Chettri 2005).
The approach to conservation and development in the 4 TBLs included codefining challenges and opportunities with institutions in partner countries sharing the landscapes, building a shared understanding of pressing issues that cut across different countries, coformulating impact pathways based on common transnational contexts and visions, and facilitating interventions promoting transboundary cooperation (Sharma and Chettri 2005;Gurung et al 2019). The theory of change pathway (Figure 3) included analysis of intermediary outcomes that served as milestones to achieve the intended long-term impact or shared goals. These were: enhanced biodiversity and ecosystem services; reduced poverty through sustainable use of rich biodiversity and sociocultural resources; enhanced resilience with better capacities, skills, institutions, and governance; and adaptive learning to combat future uncertainties (ICIMOD 2014b). The focus was on continuous deliberation, negotiations, and adaptive learning under a common regional cooperation framework (RCF) as well as on integration of multiple institutions to increase accountability and ownership among the institutions (ICIMOD et al 2017a). The long-term goals for transboundary cooperation provided various avenues for countries to discuss more-win and less-loss outcomes for biodiversity management and sustainable development in the region (Kotru et al 2020).
Process-wise, cooperation through TBLs takes time. In the context of the 4 TBLs, it took 1-2 years of consultation to set the stage for transboundary collaboration, followed by 4-5 years of joint actions and capacity enhancement and 2-3 years of evaluation and iterative refining of impact pathways (Kotru et al 2020). Designating the boundaries of a functional TBL was a crucial first step. It required an iterative, inclusive, and consultative process among a range of stakeholders comprising representatives from relevant government and nongovernment institutions, development institutions, academia, community-based institutions, and private sectors at local, subnational, and national scales (Zomer and Oli 2011). Likewise, regional-scale discussions among the countries were necessary to develop shared understanding among countries and to define long-term impact pathways for the TBL (ICIMOD 2014a; Gurung et al 2019). The other crucial step was the endorsement of the RCF as a soft guideline for cooperation jointly developed by the relevant government agencies of the individual countries (ICIMOD et al 2017a). The RCF outlined principles for regional cooperation and investments needed, partnerships, and institutional modalities. It reinforced the ownership of transboundary interventions by governments of individual countries and their commitments toward joint implementation and emphasized the roles of third-party institutions and donor partners in influencing the pace of regional cooperation.
Operationalizing the flagship Kailash Sacred Landscape initiative KSLCDI was implemented between 2011 and 2017 (Box 1). The objective was to strengthen relationships between the governments of China, India, and Nepal to mainstream sustainable ecosystem management approaches and practices into local and national policies and plans for inclusive socioeconomic development (ICIMOD 2009).
The initiative adopted 5 programmatic components: innovative livelihoods; ecosystem management; access and benefit sharing; long-term environmental and socioecological monitoring; and regional cooperation, enabling policies, and knowledge management. The initiative was reviewed through a rigorous external evaluation (Box 2). It concluded that despite a slow start transboundary cooperation has improved intercountry cooperation and was successful in terms of setting milestones and impacts through iterative consultative processes.
In the following we distill the key positive impressions from the review: Successful facilitation of shared vision and impact pathway. The process clarified knowledge, behavior, skills, and relationships among actors to identify what could be collectively achieved. Developing a shared vision served as the basis for collaborative and adaptive landscape-level planning and formalization of partners' agreements and implementation plans (ICIMOD 2013). Development of harmonized frameworks, manuals, tools, and protocols. These included a framework for long-term environmental and socioecological monitoring (Chettri et al 2015), integrated ecosystem services management ( The effectiveness of the TBLs was also highlighted in terms of interdisciplinary scientific contributions and outreach. These included understanding traditional practices and knowledge of indigenous communities (Negi et   The review also drew attention to the limitations of TBLs, particularly as a time-consuming and consultation-intensive process, requiring sensitivity to geopolitical uncertainties. If policy-level synergies are weak, impacts on the ground can be difficult to achieve or ground efforts are wasted. Also, a significant amount of time and resources are needed to address national-level institutional issues and capacities for regional cooperation. Thus, the focus remained more on implementing conservation and innovative livelihoods

Conclusion
Transboundary cooperation built on consultative and iterative dialogues-where sovereign nations have a mutual understanding of the landscape approach-has the potential to overcome cultural and historical barriers, tackle common challenges over natural resources, and promote long-term biodiversity conservation and management (ICIMOD 2019c). The TBLs in the HKH region have received global attention for their ability to facilitate mutual understanding of shared ecosystems across international boundaries and joint decision-making and management (SGS 2016). They can be a promising solution for promoting transboundary cooperation for biodiversity conservation and management through the following: Triggering collaboration with a nonpolitical entry point. This refers to technical collaborations and research on themes of global concern, such as climate change, biodiversity conservation, wildlife management, ecosystem services and valuation, and human-wildlife conflict, rather than issues of political sensitivity, such as illegal trade and migration. Codevelopment of knowledge on landscape elements, such as resource availability, distribution, and use, are vital to providing a realistic scenario for transboundary cooperation.
Communicating risk and scientific evidence. Achievements, lessons, and risks have to be regularly monitored and evaluated, and proactive communication and institutional pathways are required for the uptake of scientific findings for policies, as in the case of caterpillar fungus (Ophiocordyceps sinensis) management in KSLCDI (MoFSC 2017). The state government of Uttarakhand, India, and the national government of Nepal used scientific learnings from KSLCDI to improve the policy on and practice of managing caterpillar fungus. Essentially, this is about

BOX 1: KSLCDI objectives in 4 stages
Preparatory stage (2007)(2008) was for the countries to understand, acknowledge, and agree to the need for regional cooperation in a certain geographic area of transboundary relevance. It garnered strategic agreement toward developing the TBL initiative. Stakeholder mapping was also carried out. -up stage (2009-2010) was to begin the consultative process and develop shared understanding, carry out feasibility and baseline studies, discuss the theory of change for defining result chain logic, and prepare integrated strategies, action plans, and a cooperation framework, including regional monitoring and evaluation framework and strategies.

Start
Pre-implementation stage (2011)(2012) was to define partnerships engagement mechanisms including governance and institutional setups and communication strategies for implementation.
Implementation stage (2013)(2014)(2015)(2016)(2017) was to roll out regional-and national-level interventions related to research, management, policy, and capacity strengthening, including reflective monitoring and reviews as well as knowledge dissemination.

BOX 2: External review and evaluation of KSLCDI The KSLCDI evaluation was conducted by a third party and based on Paris Aid Effectiveness criteria as suggested by the Organisation for Economic Co-operation and Development's Development Assistance Committee (OECD-DAC). The overall rating was based on 5 criteria: relevance (are we doing the right thing?), effectiveness (can project objectives be achieved?), impact (are we contributing to the overarching result of conservation and development?), efficiency (are objectives being achieved in cost-effective ways), and sustainability (are the result achieved durable?). The initiative was rated successful with an overall score of 12.4 out of 16 points, with 14 points for relevance and sustainability, 13 for effectiveness, 12 for impact, and 9 for efficiency (ICIMOD 2019d). Prior to the external evaluation, the project also underwent a full midterm review in 2016. This included in-depth in-country assessments of the project progress.
It assessed the 5 module objectives: establishment of biodiversity corridors, adoption of approaches to ecosystem management and conservation, enhanced household incomes, organizational structure and monitoring processes of ICIMOD as the facilitating institution, and knowledge platforms for developing cooperation. The external review also considered the findings of the midterm review, which concluded that the module objective related to improving the state of ecosystems was achievable and realistic, whereas the module related to sustainable livelihoods was overambitious. Likewise, the review acknowledged the pivotal role of intergovernmental organizations, such as ICIMOD, toward facilitating collaboration and coordination at all scales-local, subnational, national, regional, and global.

careful articulation of the needs of local stakeholders and their narrowing down to ground-level conservation and development challenges, while forging cooperation between actors and sectors at scale. Developing early and inclusive partnerships. Landscape-level stakeholder interfaces support greater understanding of a TBL and the opportunities it presents. Such interfaces influence partner synergy, ownership, local stewardships, participatory planning, demand-oriented policies development, and landscape financing (eg by linking interventions to public schemes at district level).
Strengthening ownership by countries. Biodiversity management and sustainable development require longterm national commitments and investments. Efforts to leverage intra-and intercountry resources should start from the early stages of transboundary cooperation. Effective coordination with strategic, implementation, knowledge, and development partners and proactive communication of knowledge and evidence from the ground level create ownership. It is necessary to capitalize on subnational delivery systems where public investments are handled.
Creating a local-national-global cross-border interface for learning and policy influencing. Biodiversity and environmental governance need to bring positive local outcomes and must be supported through subnational and national policy mechanisms. Transboundary cooperation built upon mutual areas of interest, such as national commitments to global agendas, trigger effective crossexchange of policy learning and adoption at the national level. Regular engagement with decision-makers enhances country ownership of TBLs and strengthens existing crossborder institutional mechanisms already endorsed by countries.
In regions, such as the HKH, where the rural economy relies on the diversity of ecosystem services and benefits from biodiversity resources, the TBLs can scale the process of cooperation to restore the intricate balance between economic interests and ecological imperatives (Molden et al 2017). In the HKH region, facilitating regional cooperation for conservation and management was possible through robust partnerships among governments, academia, businesses, and civil society, complemented with effective communication and learning among the countries (Kotru et al 2020). Strong scientific evidence on the ground triggered policy engagement around key transnational issues and global commitments. Institutional efforts at all scales were vital to innovating science-practice-policy processes. Although the TBL approach comes with a wide range of risks-political sensitivity, conflicts, disasters, and security situations-it can be concluded that TBLs have the potential to be a promising solution for galvanizing regional cooperation processes to help individual countries collectively address biodiversity conservation and development-related milestones, targets, and impacts.
