○Research Subject and Objectives

Research Objectives

  The goals of the project are to promoteunderstanding of the environmental problems associated with ecologicalresources, and contribute to their solution using the concept of the ecosystemnetwork. Although our project can be regarded as a study on social-ecologicalsystems, we pay attention to the interactions among different subsystems andvarious actors in society by introducing the concept of an ecosystem network.By analyzing and integrating the case studies in the two research areas, weestablish a theory of the ecosystem network, which is expected to contribute tothe understanding and management of other ecosystems and ecological resources.

  In this project, we address twoconcrete environmental problems under contrasting ecological settings: tropicalrainforests in Southeast Asia (Sarawak,Malaysia) and grasslands in Central Asia (Mongolia). In both Sarawak and Mongolia, we are conductingresearch in three core steps: (1)identification of ecosystem network structures responsible for the problems,(2) scenario analyses, and (3) establishment of a general conservationtheory. 

 

Background

  Mostecosystems on the planet have been seriously degraded by human activities andare now in critical condition. Although various approaches for dealing withsocial-ecological systems have been developed to understand environmentalproblems and explore better ways to make both ecosystems and human livessustainable, we still do not have a clear perspective for solving the problemspartly owing to the complexity and diversity of ecosystems and human societies.

  To cope withthis complexity and diversity, we propose the concept of an “ecosystemnetwork,” which has a nested structure involving interactions among and withinsubsystems, including human societies. Most terrestrial ecosystems affected byhuman activities are a mosaic of different land covers. In the ecosystemnetwork, the subsystems (e.g., primary forests, secondary forests, lands forshifting cultivation) form an interacting network. In addition, each subsystem consistsof networks of biological interactions. Moreover, we identify different actorsin a human society within the ecosystem network, and regard human activities aspart of the interactions within the ecosystem network. Some actors do notdirectly interact with the ecosystem but indirectly through other actors.

 

Need to conduct the project at Research Institute for Humanity and Nature (RIHN)

  The project contributes to the mission ofthe RIHN because the ecosystem network is an interdisciplinary concept. Theclarification of ecosystem networks requires the close cooperation betweennatural and social scientists. In addition, the project aims to establish ageneralized theory beyond case studies; rather, it will be a core of theresearch field of the global environmental study created by RIHN.

 

Research methods

  The most important concept of this project is the “ecosystem network,” which has a nested structure involving interactions among and within subsystems, including human societies. Most terrestrial ecosystems affected by human activities are a mosaic of different land covers. In the ecosystem network, the subsystems (e.g., primary forests, secondary forests, lands for shifting cultivation) form an interacting network. In addition, each subsystem consists of networks of biological interactions. Moreover, we place human society as a subsystem within the ecosystem network and regard human activities as part of the interactions within the ecosystem network.

  The research areas for this project are a tropical rainforest in Southeast Asia (Sarawak, Malaysia) and a grassland in Central Asia (Mongolia). For a comparative investigation, it is essential to establish more than one research area to obtain generalizable results and discussion. In both study areas, terrestrial ecosystems are being devastated by the surge in Asian economies associated with the recent dramatic economic growth of China. Nevertheless, the lives of many people depend on natural ecosystems, and the destruction of these ecosystems results directly in dramatic changes in their lives. While the economies of both regions have similar frameworks, their ecological characteristics, such as the regeneration time of vegetation and the distribution of biomass in the ecosystems, differ.

  For thousands of years, livestock have extensively grazed the grasslands of Mongolia. In recent decades, however, overgrazing by livestock, especially by the increased number of goats raised for the production of cashmere for export, has caused a serious problem in the region. Overgrazing results in excessive vegetation removal from the soil surface, alkalinizes the soil, and facilitates the growth of inedible plant species.

  In Sarawak, ecosystems have changed dramatically in the last 100 years; land use has shifted from extensive agriculture in forests by indigenous people to logging in natural forests as a source of timber for export, and then to oil-palm plantations. The expansion of these plantations is thought to have brought about a sharp decrease in biodiversity and caused a reduction in or loss of ecosystem components essential to the indigenous people.

  In both Sarawak and the grasslands of Mongolia, we are conducting research in three core steps: (1) Identification of area-specific problems and hypothetical ecosystem network structures closely related to the problems; (2) confirmation and evaluation of the hypothetical links through field surveys, remote sensing, literature surveys, and modeling; and (3) scenario analyses by building a few scenarios with different network structures, and evaluation of predicted ecosystem and social status using various indices. By integrating these results, we will (4) establish a general conservation theory based on the concept of ecosystem networks. The core of the theory will indicate which network structures are likely to lead to environmental problems and how we can restore the network to mitigate the problems.

 

Organization

  The project is composed of three groups: one for the theoretical and modeling study and one group each for the field studies in Mongolia and Sarawak. To facilitate cooperation and discussion irrespective of research field, we do not divide the members of the field teams into subgroups; instead we have supervisors with a background in the social sciences and ecology for each study site. See the attached list for core and other members and their roles in the project.

○Progress and Results in 2012

(1) Scenario Analyses

  In order to present the project findings in an easily understood format, we constructed several scenarios for Mongolia and Sarawak. Each scenario includes a set of policies and institutions, based on which we use different indices to estimate land cover and forecast environmental, social, and economic conditions 30 years from the present.

  In the case of Sarawak, we examined three scenarios with different combinations of operational or planned institutions, designed by the international community to suppress overexploitation of tropical forests. While all three scenarios predicted greater retention of forests and ecosystem services compared with a Business-As-Usual scenario, the distribution of benefits among the international community, the enterprises, and the local people differed considerably.

  In Mongolia, on the other hand, the potential contribution of the international community towards maintaining ecosystem services may be relatively small. This is because grasslands in Mongolia do not have high biomass or biodiversity, and therefore, the conservation of Mongolian grasslands provides fewer ecosystem services to the international community compared with those of tropical forests. Since Mongolian grasslands are mainly used by local people, the regulation of livestock grazing by local people is essential to sustainable production.

 

(2) Implications for ecosystem conservation from the ecosystem network perspective

  We closely analyzed the ecosystem networks of Mongolia and Sarawak, and found an important difference between Mongolia and Sarawak is the relationship between enterprises and local people. Enterprises and local people have different mobility and dependence on the local ecosystems. Ecosystem deterioration affects local people more significantly than enterprises. Enterprises can utilize ecosystems in different areas if necessary, whereas local people cannot migrate as easily as the enterprises, even if their current environment becomes degraded. In Mongolia, ecological resources are used by local people and the products made are sold to the enterprises. In this manner, people and enterprises are mutually dependent. However, in the case of Sarawak, enterprises also directly exploit ecological resources, and therefore, compete with local people for the same resource base. In addition, tropical forests contain greater biodiversity and biomass and may thus have greater international importance than grasslands in terms of providing ecosystem services.

  The differences suggest that the appropriate policies and institutions would also differ between the two areas. In Mongolia, there is potential for sustainable management via a negative feedback mechanism to suppress the overuse of pastures, since the degradation of ecological resources and other ecosystem services directly affects the users. For sustainable management, it is therefore essential to identify factors that weaken feedback mechanisms and to implement policies and institutions that enhance such feedback. In contrast, feedback does not act to suppress overuse in Sarawak, where the main users are enterprises. In this case, sustainable management therefore requires policies to introduce feedback or restrict the intensity of resource use.

  The differences in productivity and biomass (or resource) distribution of the two ecosystems may be one of the main factors in the differing structures between the two areas. In grasslands, resources are scattered and both spatially and temporarily unpredictable, owing to low productivity and rapid turnover of one to several years. Harvesting such resources does not attract enterprises, which seek to maximize the return from their investment. Enterprises therefore choose to buy products from local people rather than exploit the resources themselves. In contrast, biomass produced for more than 100 years is accumulated above ground in Sarawak. Therefore, biomass is significant and evenly distributed, which is highly attractive to enterprises.

 

(3) Publication of project achievements

  We organized RIHN international symposium together with three other projects. The papers in the symposium will be published as two books in the RIHN series published by Springer. Besides, we organized symposia in Mogolia and Japan, and publish books in English and Mongolian language. We are editing two Japanese books.
