Mountain forest ecosystems provide a wide range of benefits, not only to local residents, but to those living downstream: from reducing floods to stabilizing slopes and supporting rich biodiversity.

Understanding these contributions is key to sustainably managing mountain forest services — but large-scale assessments are still rare, especially in data-poor regions.

In response, scientists at the Center for International Forestry Research (CIFOR) and partner institutions, including from the CGIAR Research Program on Forests, Trees and Agroforestry (FTA), compiled in a new working paper the most relevant tools and approaches to assess the sociocultural, economic and ecological values of mountain forest ecosystems, with a focus on southern Asia.

“This working paper wants to help researchers and land managers understand the various assessment methods, so that they are able apply them in their own countries and landscapes,” says lead author and CIFOR senior scientist, Himlal Baral of FTA.

Understanding the direct and indirect benefits of forest ecosystems to human well-being is important globally, but especially so in mountainous areas, as illustrated in the paper by case studies in Bhutan, India, Indonesia, Iran and Nepal.

Steep slopes and elevation create geographical barriers to accessing mountain forest landscapes, meaning that “local communities are isolated from urban areas, and so rely heavily on mountain forest ecosystem services for basic needs such as food,” explains Baral. In many cases, mountain people are also more vulnerable to climate change and poverty, he says.

At the same time, natural geographical barriers often result in communities with their own distinct cultures and social systems, and in “more primary forests, higher carbon stocks and richer biodiversity compared with lowland areas,” states the paper.

MULTIPLE TOOLS

Gauging stakeholders’ perspectives, analyzing markets and scenario modeling are three ways of assessing ecosystem services. “Some of these approaches are simple, user-friendly and readily available,” Baral points out. “Even people with little experience and technical expertise can use them.”

The various tools falling into these three categories are differentiated in terms of required data, technical capacity, time and cost, and “have their own strengths of being able to assess a particular value,” notes the paper.

This means they can be jointly implemented to assess multiple values of mountain forest ecosystem services, and to shed light on the trade-offs and synergies between them. For example, “restoration efforts to enhance one service could compromise — or improve — another service.”

A case study in Nepal’s community forests, for instance, illustrates the combination of free-access satellite images, repeat photography, and participatory approaches to engaging local communities and experts.

The paper indicates this three-pronged approach “can be used to quickly map and prioritize ecosystem services’ values,” and to demonstrate the positive impact of restoration efforts over the last two decades.

In Bhutan, a tool known as benefit-transfer showed that the average total value of forest ecosystem services was over USD 14.5 billion per year, while in India, stakeholder and household analyses revealed that local livelihoods near the Maguri Mottapung wetland hinge on 29 ecosystem services — something that “suggests the urgent need for a participatory management plan engaging local communities.”

JOINT LEARNING

For Laxmi Dutt Bhatta, a senior ecosystem management specialist at ICIMOD and co-author of the paper, the assessment of ecosystem services is key to “showing the overall value of forests to countries and communities; to following up their evolution, and to informing decision-making.”

Co-author Sonam Phuntsho, who is a senior forestry officer at the Ugyen Wangchuck Institute for Conservation and Environmental Research (UWICER), agrees: “Forests are a critical natural asset in Bhutan, where the majority of the population directly depends on forests for various services. But there is very limited information on their value so far.”

From Phuntsho’s perspective, having an overview of studies and methodologies in the region is now “extremely useful” for the country, as payment for ecosystem services is gradually picking up.

In Indonesia, the so-called Q methodology has helped lay the ground for payment of ecosystem services by identifying stakeholders’ anticipated benefits and concerns, while the study in Nepal “could be very much replicated in Bhutan, given the rapid increase in community forests,” Phuntso says.

NEXT STEPS

Assessing mountain forest ecosystem services brings opportunities, but also challenges that must be reflected in assessment design.

These include the complexity of defining and classifying ecosystem services, intricate relationships among services including trade-offs and synergies, and the limitation of assessments to build successful payments for services.

Bhatta highlights two additional issues that will have to be addressed to understand the evolution of such services in the next 50 years: uncertainties associated with climate change and the scarcity of data on mountain forest ecosystem services, especially in data-poor regions such as South Asian mountains, and the Hindu Kush Himalayas.

Despite these challenges, lead author Himlal Baral is hopeful about the future of ecosystem service-based management. “In the past, forests just meant timber to many, but awareness is increasing,” he says.

“Now, a growing number of people associate forests with mitigation of climate change, water, biodiversity and landslide protection, so we are moving in the right direction.”

Approaches and tools for assessing mountain forest ecosystem services

Mountain forest ecosystems provide a wide range of direct and indirect contributions to the people who live in the mountains and surrounding areas. Occupying steep slopes at high elevation, these ecosystems provide services such as stabilizing slopes, regulating hydrological cycles, maintaining rich biodiversity and supporting the livelihoods of those who are diverse in culture but vulnerable to poverty and food security. This paper (i) reviews several tools for assessing the sociocultural, economic and ecological values of mountain forest ecosystem services, (ii) demonstrates case studies of tool applications from several countries namely, Bhutan, India, Indonesia, Iran and Nepal, and (iii) discusses assessment challenges that should be considered in the application of these tools.

In Bhutan, an application of benefit transfer showed that the average total value of forest ecosystem services was over USD 14.5 billion per year. In India, an application of stakeholder and household analyses indicated that a total of 29 different ecosystem services are available and sustain livelihoods of local communities near the Maguri Mottapung wetland. In Indonesia, an application of Q methodology identified anticipated benefits and concerns of forest watershed stakeholders related to certification applications for a payment for ecosystem services. In Iran, an application of the Integrated Valuation of Ecosystem Services and Trade-offs Tool showed that the regulation of ecosystem services has been declining in Hyrcanian forests despite the forests’ critical roles in the region. In Nepal, an application of a spatial analytical approach and participatory assessment techniques identified key mountain ecosystem services for community forests at the Charnawolti sub-watershed of Dolakha, and demonstrated forest restoration on degraded lands over the last two decades. Several challenges exist for the assessment of mountain forest ecosystem services and these must be reflected in assessment design. These challenges include the complexity of defining and classifying ecosystem services; limited availability of data on ecosystem services; uncertainties associated with climate change; complex relationships among services including trade-offs and synergies; and limitation of assessments to build successful payments for ecosystem services.

Gendered Responses to Drought in Yunnan Province, China

Vulnerability to and perceptions of climate change may be significantly affected by gender. However, in China, gender is rarely addressed in climate adaption or resource management strategies. This paper demonstrates the relevance of gender in responses to climate change in the mountainous province of Yunnan in southwest China.

Based on surveys undertaken during a record-breaking drought, the paper explores how women and men in a village in Baoshan Prefecture differ in their perceptions of and responses to drought, and how the changing roles of women and men in the home and the community are influencing water management at the village level.

Our results show that despite the increasingly active role of women in managing water during the drought, they are excluded from community-level decision-making about water. The paper argues that given the importance of gender differences in perceptions of and responses to drought, the lack of a gender perspective in Chinese policy may undermine efforts to support local resource management and climate adaptation.
