An operational model for mainstreaming ecosystem services for implementation

Research on ecosystem services has grown markedly in recent years. However, few studies are embedded in a social process designed to ensure effective management of ecosystem services. Most research has focused only on biophysical and valuation assessments of putative services. As a mission-oriented discipline, ecosystem service research should be user-inspired and user-useful, which will require that researchers respond to stakeholder needs from the outset and collaborate with them in strategy development and implementation. Here we provide a pragmatic operational model for achieving the safeguarding of ecosystem services. The model comprises three phases: assessment, planning, and management. Outcomes of social, biophysical, and valuation assessments are used to identify opportunities and constraints for implementation. The latter then are transformed into user-friendly products to identify, with stakeholders, strategic objectives for implementation (the planning phase). The management phase undertakes and coordinates actions that achieve the protection of ecosystem services and ensure the flow of these services to beneficiaries. This outcome is achieved via mainstreaming, or incorporating the safeguarding of ecosystem services into the policies and practices of sectors that deal with land- and water-use planning. Management needs to be adaptive and should be institutionalized in a suite of learning organizations that are representative of the sectors that are concerned with decision-making and planning. By following the phases of our operational model, projects for safeguarding ecosystem services are likely to empower stakeholders to implement effective on-the-ground management that will achieve resilience of the corresponding social-ecological systems.

Let the locals lead.

To save biodiversity, on-the-ground agencies need to set the conservation research agenda, not distant academics and non-governmental organizations, argue Robert J. Smith and colleagues.

The role of participatory modeling in landscape approaches to reconcile conservation and development

Conservation organizations are increasingly turning to landscape approaches to achieve a balance between conservation and development goals. We use six case studies in Africa and Asia to explore the role of participatory modeling with stakeholders as one of the steps towards implementing a landscape approach. The modeling was enthusiastically embraced by some stakeholders and led to impact in some cases. Different stakeholders valued the modeling exercise differently. Noteworthy was the difference between those stakeholders connected to the policy process and scientists; the presence of the former in the modeling activities is key to achieving policy impacts, and the latter were most critical of participatory modeling. Valued aspects of the modeling included stimulating cross-sector strategic thinking, and helping participants to confront the real drivers of change and to recognize trade-offs. The modeling was generally considered to be successful in building shared understanding of issues. This understanding was gained mainly in the discussions held in the process of building the model rather than in the model outputs. The model itself reflects but a few of the main elements of the usually rich discussions that preceded its finalization. Problems emerged when models became too complex. Key lessons for participatory modeling are the need for good facilitation in order to maintain a balance between “models as stories” and technical modeling, and the importance of inviting the appropriate stakeholders to achieve impact.

Improving the Key Biodiversity Areas Approach for Effective Conservation Planning

ABSTRACT The key biodiversity areas (KBA) approach aims to identify globally important areas for species conservation. Although a similar methodology has been used successfully to identify Important Bird Areas, we have identified five limitations that may apply when considering other taxa: The KBA approach is overly prescriptive in identifying important conservation features, is inflexible when dealing with landscape connectivity, creates errors by applying global criteria without input from local experts, relies on post hoc consideration of implementation opportunities and constraints, and fails to automatically involve implementation agencies in the assessment process. We suggest three modifications to the present approach: (1) Provide training in regional conservation planning for local stakeholders, (2) expand the Alliance for Zero Extinction program to include a broader range of threatened species, and (3) allow local stakeholders to nominate KBAs on the basis of their own regional conservation assessments. These modifications would build on the expertise of those promoting the KBA approach and help maintain the diversity of methods that are needed to conserve biodiversity effectively.

Meta-analysis of attitudes toward damage-causing mammalian wildlife.

Many populations of threatened mammals persist outside formally protected areas, and their survival depends on the willingness of communities to coexist with them. An understanding of the attitudes, and specifically the tolerance, of individuals and communities and the factors that determine these is therefore fundamental to designing strategies to alleviate human-wildlife conflict. We conducted a meta-analysis to identify factors that affected attitudes toward 4 groups of terrestrial mammals. Elephants (65%) elicited the most positive attitudes, followed by primates (55%), ungulates (53%), and carnivores (44%). Urban residents presented the most positive attitudes (80%), followed by commercial farmers (51%) and communal farmers (26%). A tolerance to damage index showed that human tolerance of ungulates and primates was proportional to the probability of experiencing damage while elephants elicited tolerance levels higher than anticipated and carnivores elicited tolerance levels lower than anticipated. Contrary to conventional wisdom, experiencing damage was not always the dominant factor determining attitudes. Communal farmers had a lower probability of being positive toward carnivores irrespective of probability of experiencing damage, while commercial farmers and urban residents were more likely to be positive toward carnivores irrespective of damage. Urban residents were more likely to be positive toward ungulates, elephants, and primates when probability of damage was low, but not when it was high. Commercial and communal farmers had a higher probability of being positive toward ungulates, primates, and elephants irrespective of probability of experiencing damage. Taxonomic bias may therefore be important. Identifying the distinct factors explaining these attitudes and the specific contexts in which they operate, inclusive of the species causing damage, will be essential for prioritizing conservation investments. Meta-Análisis de las Posturas hacia la Mamíferos Silvestres Causantes de Daños Resumen Muchas poblaciones de mamíferos amenazados persisten fuera de áreas protegidas formales y su supervivencia depende de la buena voluntad de las comunidades que coexisten con ellos. Un entendimiento de las posturas, y específicamente de la tolerancia, de los individuos y las comunidades y los factores que los determinan es fundamental para diseñar estrategias que alivien el conflicto humano – vida silvestre. Llevamos a cabo un meta-análisis para identificar los factores que afectaron las posturas hacia cuatro grupos de mamíferos terrestres. Los elefantes (65%) provocaron las posturas más positivas. Los siguieron los primates (55%), los ungulados (53%) y los carnívoros (44%). Los residentes urbanos presentaron las posturas más positivas (80%), seguidos por los granjeros comerciales (51%) y los granjeros comunales (26%). Un índice de tolerancia a los daños mostró que la tolerancia humana a los ungulados y primates fue proporcional a la probabilidad de experimentar daños mientras que los elefantes provocaron niveles de tolerancia más altos de lo esperado y los carnívoros provocaron niveles de tolerancia más bajos de lo esperado. Contrario a la sabiduría convencional, experimentar daños no fue siempre el factor dominante para determinar las posturas. Los granjeros comunales tuvieron una baja probabilidad de ser positivos hacia los carnívoros independientemente de la probabilidad de experimentar daños, mientras que los granjeros comerciales y los residentes urbanos tuvieron mayor probabilidad de ser positivos hacia los carnívoros independientemente de los daños. Los residentes urbanos tuvieron mayor probabilidad de ser positivos hacia los ungulados, los elefantes y los primates cuando la probabilidad de daños fue baja, pero no cuando fue alta. Los granjeros comerciales y comunales tuvieron una mayor probabilidad de ser positivos hacia los ungulados, los primates y los elefantes independientemente de la probabilidad de experimentar daños. El prejuicio taxonómico por eso puede ser importante. El identificar los distintos factores que explican estas posturas y los contextos específicos en los cuales operan, inclusivo de especies que causan daños, será esencial para priorizar las inversiones en la conservación.

Exploiting viral cell-targeting abilities in a single polypeptide, non-infectious, recombinant vehicle for integrin-mediated DNA delivery and gene expression.

A recombinant, multifunctional protein has been designed for optimized, cell-targeted DNA delivery and gene expression in mammalian cells. This hybrid construct comprises a viral peptide ligand for integrin alpha(V)beta(3) binding, a DNA-condensing poly-L-lysine domain, and a complete, functional beta-galactosidase protein that serves simultaneously as purification tag and DNA-shielding agent. This recombinant protein is stable; it has been produced successfully in Escherichia coli and can be purified in a single step by affinity chromatography. At optimal molar ratios, mixtures of this vector and a luciferase-reporter plasmid form stable complexes that transfect cultured cells. After exposure to these cell-targeted complexes, steady levels of gene expression are observed for more than 3 days after transfection, representing between 20 and 40% of those achieved with untargeted, lipid-based DNA-condensing agents. The principle to include viral motifs for cell infection in single polypeptide recombinant proteins represents a promising approach towards the design of non-viral modular DNA transfer vectors that conserve the cell-target- ing specificity of native viruses and that do not need further processing after bioproduction in a recombinant host.

A multi-domain protein system based on the HC fragment of tetanus toxin for targeting DNA to neuronal cells.

One goal of gene therapy is the targeted delivery of therapeutic genes to defined tissues. One attractive target is the central nervous system as there are several neuronal degenerative diseases which may be amenable to gene therapy. At present there is a lack of delivery systems that are able to target genes specifically to neuronal cells. Multi-domain proteins were designed and constructed to facilitate the delivery of exogenous genes to neuronal cells. Neuronal targeting activity of the proteins was achieved by inclusion of the HC fragment of tetanus toxin (TeNT), a protein with well-characterised tropism for the central nervous system. The yeast Gal4 DNA-binding domain enabled specific binding of DNA while the translocation domain from diphtheria toxin (DT) was included to facilitate crossing of the endosomal vesicle. One multi-domain protein, containing all three of these domains, was found to transfect up to 8% of neuroblastoma N18-RE105 cells with marker genes. Monitoring the transfection by confocal microscopy indicated that this protein-DNA transfection complex is to some extent localised at the cell surface, suggesting that further improvements to translocating this membrane barrier may yield higher transfection levels. The demonstration that this multi-domain protein can target genes specifically to neuronal cells is a first step in the development of novel vectors for the delivery of genes with therapeutic potential to diseased neuronal tissues.

Being smart about SMART environmental targets

Focus on the negotiation process, not just the end target Global progress toward meeting the Convention on Biological Diversity (CBD) Aichi targets has recently been found wanting (1). The Aichi targets were intended to be SMART (specific, measurable, ambitious, realistic, and time-bound), partly in response to the perception that failure to meet the preceding global biodiversity targets resulted from their lack of SMART-ness (2). Negotiations are building toward the September 2015 United Nations meeting on Sustainable Development Goals (SDGs), which will influence government and business development priorities for decades. Some argue that scientists must engage with the SDG negotiation process to ensure that the environmental targets (e.g., sustainable food production and water-use efficiency) are not vague, modest, or lacking in detailed quantification (3). We caution against focusing only on ensuring that environmental targets are SMART and call for greater attention on the processes that lead to a target being set and met.

A Multidisciplinary Conceptualization of Conservation Opportunity

An opportunity represents an advantageous combination of circumstances that allows goals to be achieved. We reviewed the nature of opportunity and how it manifests in different subsystems (e.g., biophysical, social, political, economic) as conceptualized in other bodies of literature, including behavior, adoption, entrepreneur, public policy, and resilience literature. We then developed a multidisciplinary conceptualization of conservation opportunity. We identified 3 types of conservation opportunity: potential, actors remove barriers to problem solving by identifying the capabilities within the system that can be manipulated to create support for conservation action; traction, actors identify windows of opportunity that arise from exogenous shocks, events, or changes that remove barriers to solving problems; and existing, everything is in place for conservation action (i.e., no barriers exist) and an actor takes advantage of the existing circumstances to solve problems. Different leverage points characterize each type of opportunity. Thus, unique stages of opportunity identification or creation and exploitation exist: characterizing the system and defining problems; identifying potential solutions; assessing the feasibility of solutions; identifying or creating opportunities; and taking advantage of opportunities. These stages can be undertaken independently or as part of a situational analysis and typically comprise the first stage, but they can also be conducted iteratively throughout a conservation planning process. Four types of entrepreneur can be identified (business, policy, social, and conservation), each possessing attributes that enable them to identify or create opportunities and take advantage of them. We examined how different types of conservation opportunity manifest in a social-ecological system (the Great Barrier Reef) and how they can be taken advantage of. Our multidisciplinary conceptualization of conservation opportunity strengthens and legitimizes the concept.
