Privacy Risks

Through volunteering data, people can help assess information on various aspects of their surrounding environment. Particularly in natural resource management, Volunteered Geographic Information (VGI) is increasingly recognized as a significant resource, for example, supporting visitation pattern analysis to evaluate collective values and improve natural well-being. In recent years, however, user privacy has become an increasingly important consideration. Potential conflicts often emerge from the fact that VGI can be re-used in contexts not originally considered by volunteers. Addressing these privacy conflicts is particularly problematic in natural resource management, where visualizations are often explorative, with multifaceted and sometimes initially unknown sets of analysis outcomes. In this paper, we present an integrated and component-based approach to privacy-aware visualization of VGI, specifically suited for application to natural resource management. As a key component, HyperLogLog (HLL)—a data abstraction format—is used to allow estimation of results, instead of more accurate measurements. While HLL alone cannot preserve privacy, it can be combined with existing approaches to improve privacy while, at the same time, maintaining some flexibility of analysis. Together, these components make it possible to gradually reduce privacy risks for volunteers at various steps of the analytical process. A specific use case demonstration is provided, based on a global, publicly-available dataset that contains 100 million photos shared by 581,099 users under Creative Commons licenses. Both the data processing pipeline and resulting dataset are made available, allowing transparent benchmarking of the privacy–utility tradeoffs.

The Past

Although humans need ecosystems and ecosystem services for their survival and well-being, most of the global ecosystems and the services that they provide have declined and/or degraded rapidly over the past few decades. In order to find the ways to sustainably use natural resources, substantial efforts have been made to measure and value the ecosystem services. The term ‘ecosystem service’ was interpreted in different ways in the literature. For making correct decisions in natural resource management, a consistent way of defining and classifying ecosystem services is needed for valuation purposes. This paper argued for the need to divide ecosystem services into intermediate and final services.

The Impact

Climate change is having a significant impact on the global ecosystem and is likely to become increasingly important as this phenomenon intensifies. Numerous studies in climate change impacts on biodiversity, ecosystems, and ecosystem services in China have been published in recent decades. However, a comprehensive review of the topic is needed to provide an improved understanding of the history and driving mechanisms of environmental changes within the region. Here we review the evidence for changes in climate and the peer-reviewed literature that assesses climate change impacts on biodiversity, ecosystem, and ecosystem services at a China scale. Our main conclusions are as follows. (1) Most of the evidence shows that climate change (the increasing extreme events) is affecting the change of productivity, species interactions, and biological invasions, especially in the agro-pastoral transition zone and fragile ecological area in Northern China. (2) The individuals and populations respond to climate change through changes in behavior, functions, and geographic scope. (3) The impact of climate change on most types of services (provisioning, regulating, supporting, and cultural) in China is mainly negative and brings threats and challenges to human well-being and natural resource management, therefore, requiring costly societal adjustments. In general, although great progress has been made, the management strategies still need to be further improved. Integrating climate change into ecosystem services assessment and natural resource management is still a major challenge. Moving forward, it is necessary to evaluate and research the effectiveness of typical demonstration cases, which will contribute to better scientific management of natural resources in China and the world.

Community-based Natural Resource Management (CBNRM) focuses on the collective management of ecosystems to promote human well-being and aims to devolve authority for ecosystem management to the local (community) level. CBNRM therefore requires strong investments in capacity development of local institutions and governance structures. CBNRM has come under strong criticism for its failures to deliver real benefits to communities. In this paper we explore the reasons for the frequent failure of CBNRM. We postulate that good governance buffers CBNRM against unexpected change, notably conflicts, especially in the early stages when income generation, infrastructure development and capacity development have not yet taken place. We assess the key characteristics of CBNRM governance systems that could perform this buffering function, using case study examples from Macubeni, Nqabara, Makuleke and Richtersveld to support our propositions. In our case studies, 11 strategies have been used to increase the incidence of success of CBNRM: understand and describe the social-ecological system; establish and communicate a clear vision; build on local organizations; plan ahead; create rules for resource use and enforce them; communicate the vision, plan and rules; develop management capacity; finance the initial stages of the initiative; work within available legal frameworks; monitor and learn all the time; and create lasting incentives. Despite these strategies there are, however, a number of obstinate implementation challenges, related to governance shortcomings and external factors which management cannot control. We therefore propose seven additional strategies to promote good governance in CBNRM: 1. Develop knowledge networks that draw on the experience and wisdom of a wide range of key individuals. 2. Establish formalised decision-making structures (e.g. multi-level project steering committees) with clear constitutions and codes of conduct. 3. Clearly define and legitimise conflict resolution procedures. 4. Ensure acceptance of the governance structure by community members. 5. Obtain formal commitment to well-defined roles and responsibilities by key individuals. 6. Establish tangible incentives to key individuals for meeting their commitments. 7. Develop the capacity for facilitation to promote communication. Local communities, government and scientists have important roles to play in maintaining these knowledge and governance networks through adaptive co-management.
