Adaptation Policies for Biodiversity: Facilitated Dispersal

Professor Ove Hoegh-Guldberg of Queensland University and colleagues have an important article on “Assisted Colonization and Rapid Climate Change” in this week’s issue of Science (pdf). The author’s argue:

Rapid climatic change has already caused changes to the distributions of many plants and animals, leading to severe range contractions and the extinction of some species (1, 2). The geographic ranges of many species are moving toward the poles or to higher altitudes in response to shifts in the habitats to which these species have adapted over relatively longer periods (1-4). It already appears that some species are unable to disperse or adapt fast enough to keep up with the high rates of climate change (5, 6). These organisms face increased extinction risk, and, as a result, whole ecosystems, such as cloud forests and coral reefs, may cease to function in their current form (7-9).
Current conservation practices may not be enough to avert species losses in the face of mid- to upper-level climate projections (>3°C) (10), because the extensive clearing and destruction of natural habitats by humans disrupts processes that underpin species dispersal and establishment. Therefore, resource managers and policy-makers must contemplate moving species to sites where they do not currently occur or have not been known to occur in recent history. This strategy flies in the face of conventional conservation approaches.

The strategy flies in the face of conventional conservation approaches due to the numerous risks associated with the introduction of invasive species. The authors fully acknowledge these risks.

The world is littered with examples where moving species beyond their current range into natural and agricultural landscapes has had negative impacts. Understandably, notions of deliberately moving species are regarded with suspicion. Our contrary view is that an increased understanding of the habitat requirements and distributions of some species allows us to identify low-risk situations where the benefits of such "assisted colonization'" can be realized and adverse outcomes minimized…
…One of the most serious risks associated with assisted colonization is the potential for creating new pest problems at the target site. Introduced organisms can also carry diseases and parasites or can alter the genetic structure and breeding systems of local populations…
…In addition to the ecological risks, socioeconomic concerns must be considered in decisions to move threatened species. Financial or human safety constraints, for example, may make a species' introduction undesirable. It is likely to be unacceptable to move threatened large carnivores or toxic plants into regions that are important for grazing livestock…

These risks do not invalidate the authors' major point. If we want to conserve current biodiversity in a changing climate, we will likely need creative alternatives to current conservation approaches. Facilitated dispersal of species is one option that deserves consideration in specific conservation contexts. However, it is far from a silver bullet.

Fewer Endangered Species

Hey, amazing. The world is getting safer for critters. Dirk Kempthorne, Secretary of the Interior, hasn't declared a single animal or plant species endangered or threatened since he took office in 2006. What a relief! Just eight years ago, animals and plants were going down like bowling pins. Now they're thriving. Maybe all that development wasn't so bad after all.

Bridge, anyone?

Expertise in Biodiversity Governance

Last week I had the opportunity to participate in an excellent workshop on the role of expertise in biodiversity governance. The workshop was an exercise in the design of a new science-policy organization/institution. The workshop was titled "International Science-Policy Interfaces for Biodiversity Governance" and was held at the UFZ Centre for Environmental Research in Leipzig, Germany. At the workshop participants produced a set of consensus recommendations for the role of an institution that would provide expert advice in the international arena of biodiversity policy.

The main motivation for the workshop is a current consultation seeking such recommendations, called IMoSEB, organized by the French government. You can find our workshop recommendations here in PDF, and also below in HTML. Your comments on the recommendations and the more general challenge of exert advice in the area of biodiversity would be welcomed.

Leipzig Workshop Recommendations for a Knowledge-Policy Interface for Biodiversity Governance

4 October 2006

This document contributes to ongoing debates, including the IMoSEB consultation process, seeking to identify the optimal niche and conditions for the creation of an independent and effective international knowledge-policy interface1 for biodiversity governance. A knowledge-policy interface is essential to support more effective biodiversity-related decision making and societal responses to the challenges of achieving sustainable development.

Mandate:

• Synthesize and communicate a knowledge base on biodiversity in support of decision making and implementation
• Bring together and acknowledge diverse understandings, perspectives, and values regarding biodiversity loss and change
• Create a mechanism for dialogue and exchange among holders of diverse knowledge and knowledge systems (i.e., all forms of traditional and modern knowledge and science)
• Foster deeper understanding of the ways in which biodiversity loss and change transcend scales (spatial, temporal, etc.) and jurisdictional boundaries
• Through its activities enhance and improve abilities to collect, exchange and disseminate knowledge and information, and promote actions in favor of better biodiversity management at all levels
Outputs and outcomes:
• Scenarios of human futures and biodiversity loss and change, in relation to poverty, food security, economic growth, water security, conflict, human health, energy, climate change, etc. illuminating policy options, choices, and strategies available to diverse actors
• Periodic assessments of:

o existing biodiversity knowledges, including identification of gaps in existing assessments,
o status and trends on biodiversity,
o strategies and options for response,
o policy effectiveness,
o capacity at all levels of decision making
o biodiversity knowledge-policy interfaces, and
o cross-issue linkages (e.g., poverty, food security, economic growth, water security, conflict, human health, energy, climate change)

• Analyses of the causes of biodiversity loss and change, including key aspects of political economies2, and the necessary elements of societal transformation to redress these causes
• Stock-taking and management of biodiversity knowledge, including for global trends, indicators, and monitoring systems

1 We use the phrase “knowledge-policy interface” to acknowledge that information and expertise relevant to policy must include all forms of knowledge.

2 In this context we understand political economy as the analysis of economic and political dynamics, power structures, regulations, policies and dominant ideologies that affect biodiversity and people’s relation to it.

• Comprehensive outreach and communication strategy in support of dialogue and action
• Identification of knowledge gaps and feedback into research policies and priorities
• Identification of gaps in capacity for linking biodiversity knowledge to action at all levels of decision making and implementation
• Creation and dissemination of tools and methodologies for assessments, analyses, and other means of connecting knowledge and policy

Process:

• Ongoing, dynamic, and independent process that brings together diverse forms of knowledge, expertise, and science
• Ensure that process is legitimate and has appropriate institutional support and authorizing environment
• Establish secure funding stream from multiple sources
• Engage governments, private sector, civil society, scientific community, indigenous communities, international organizations and conventions, etc., in the design and operation of the mechanism
• Networking process that links and builds upon—and does not reinvent or duplicate—diverse existing networks of biodiversity expertise and policy
• Innovating process that identifies and seeks to fill gaps in existing networks of biodiversity expertise and policy
• Catalyze nested networks and activities at national and sub-global (e.g., local, regional, trans-jurisdictional) levels
• Process that ensures interpretation and translation among relevant languages, cultures, and knowledge traditions
• Provide regular opportunities for appropriate internal and external evaluation and review
• Establish small and effective coordinating mechanism (e.g., governing board) that includes appropriate balance and diversity across geography, sectors, stakeholders, expertise, etc.

Questions requiring further reflection

Participants agreed that future consultations will require careful consideration of the following key questions given the reality of trade-offs among democratization of expertise, stakeholder involvement, political legitimacy and accountability, funding mandates, scientific excellence, trust and credibility, etc.:

• What is the appropriate form of funding, institutional framework, and authorization of the mechanism by governments, international conventions, and the United Nations system while maintaining independence?
• What are the appropriate means for developing the network described above?
• How to link the mechanism to the needs of the various international conventions?
