Dans le domaine de la gestion des ressources naturelles, la gestion adaptative, est un processus robuste de prise de décision face à l'incertitude, basé sur une approche itérative, et visant à réduire l'incertitude au-cours du temps grâce à un système de suivi et d'observation. De cette manière, le processus de prise de décision peut répondre simultanément à plusieurs objectifs de gestion des ressources. Le management adaptatif permet de changer un système mais aussi de mieux comprendre son fonctionnement. En étant basé sur un processus d'apprentissage, il permet d'améliorer l'efficacité à long terme de la gestion. La difficulté de la gestion adaptative est de trouver le bon équilibre entre acquisition de connaissances sur le fonctionnement du système (pour améliorer son fonctionnement à long terme) et gestion efficace du système à cours terme (en utilisant les connaissances limitées disponibles).

Objectifs

Les principes de base de la gestion adaptative incluent :

1. La gestion doit se faire à des échelles temporelles et spatiales adéquates
2. La gestion doit prendre en compte la puissance statistiques et la présence de témoins positifs ou négatifs, dans son processus d'acquisition de données et de connaissances
3. L'utilisation de la modélisation numérique pour construire une consensus écologique
4. Utilisation du consensus écologique pour élaborer des stratégies alternatives
5. Diffusion des alternatives dans les espaces de discussion politique

La mise en place de ces principes requière un processus de gestion ouvert, cherchant à impliquer les parties prenantes passées, présentes et futures. La gestion adaptative est un processus à la fois scientifique et social. Il se concentre sur le développement de nouvelles institutions et stratégies institutionnelles en lien avec le développement de théories scientifiques et d'approches expérimentales (resilliance.org).

La gestion adaptative peut être active ou passive, suivant la manière dont se déroule l'apprentissage. L'approche passive n'utilise l'apprentissage que lorsqu'il permet de répondre à des besoins précis. L'approche active inclue l'apprentissage parmi ses objectifs. Dans les deux cas, les connaissances nouvellement acquises sont intégrées dans les modèles et de nouvelles stratégies de gestion en sont tirées.

Features

Key features of both passive and active adaptive management are:

• Iterative decision-making (evaluating results and adjusting actions on the basis of what has been learned)
• Feedback between monitoring and decisions (learning)
• Explicit characterization of system uncertainty through multi-model inference
• Bayesian inference
• Embracing risk and uncertainty as a way of building understanding

However, a number of process failures related to information feedback can prevent effective adaptive management decision making:

1. data collection is never completely implemented;
2. data are collected but not analyzed;
3. data are analyzed but results are inconclusive;
4. data are analyzed and are interesting, but are not presented to decision makers;
5. data are analyzed and presented, but are not used for decision-making because of internal or external factors

History

L'invention du concept de gestion adaptative peut être attribuée à Frederick Taylor, qui développa la "gestion scientifique" dans les années 1900 (Haber, 1964). Deux écologues de l'Université de Colombie Britannique, C.S. Holling et C.J. Walters, développent l'approche de gestion adaptative dnas les années 1970-1980 et font la distincition entre l'approche apssive et l'approche active. Kai Lee, un physicien de Princeton, further developed the adaptive management approach as they distinguished between passive and active adaptive management practice. Kai Lee, notable Princeton physicist, expanded upon the approach in the late 1970s and early 1980s while pursuing a post-doctorate degree at UC Berkeley. The approach was further developed at the International Institute for Applied Systems Analysis (IIASA) in Vienna, Austria, while C.S. Holling was director of the Institute. In 1992, Hilbourne described three learning models for federal land managers, around which adaptive management approaches could be developed, these are reactive, passive and active.

Adaptive management has probably been most frequently applied in Yap, Australia and North America, initially applied in fishery management, but received more broad application in the 1990s and 2000s. One of the most successful applications of adaptive management has been in the area of waterfowl harvest management in North America, most notably for the mallard.

Adaptive management in a conservation project and program context can trace its roots back to at least the early 1990s, with the establishment of the Biodiversity Support Program (BSP) in 1989. BSP was a USAID-funded consortium of WWF, The Nature Conservancy (TNC), and World Resources Institute (WRI). Its Analysis and Adaptive Management Program sought to understand the conditions under which certain conservation strategies were most effective and to identify lessons learned across conservation projects. When BSP ended in 2001, TNC and Foundations of Success (FOS, a non-profit which grew out of BSP) continued to actively work in promoting adaptive management for conservation projects and programs. The approaches used included Conservation by Design (TNC) and Measures of Success (FOS).

In 2004, the Conservation Measures Partnership (CMP) – which includes several former BSP members – developed a common set of standards and guidelines for applying adaptive management to conservation projects and programs.

Use in environmental practices

Applying adaptive management in a conservation project or program involves the integration of project/program design, management, and monitoring to systematically test assumptions in order to adapt and learn. The three components of adaptive management in environmental practice are:

• Testing Assumptions is about systematically trying different actions to achieve a desired outcome. It is not, however, a random trial-and-error process. Rather, it involves using knowledge about the specific site to pick the best known strategy, laying out the assumptions behind how that strategy will work, and then collecting monitoring data to determine if the assumptions hold true.
• Adaptation involves changing assumptions and interventions to respond to new or different information obtained through monitoring and project experience.
• Learning is about explicitly documenting a team’s planning and implementation processes and its successes and failures for internal learning as well as learning across the conservation community. This learning enables conservation practitioners to design and manage projects better and avoid some of the perils others have encountered. Learning about a managed system is only useful in cases where management decisions are repeated.

Application to environmental projects and programs

Open Standards for the Practice of Conservation lay out 5 main steps to an adaptive management project cycle (see Figure 1). The Open Standards represent a compilation and adaptation of best practices and guidelines across several fields and across several organizations within the conservation community. Since the release of the initial Open Standards (updated in 2007 and 2013), thousands of project teams from conservation organizations (e.g., TNC, Rare, and WWF), local conservation groups, and donors alike have begun applying these Open Standards to their work. In addition, several CMP members have developed training materials and courses to help apply the Standards.

Some recent write-ups of adaptive management in conservation include: wildlife protection (SWAP, 2008), forests ecosystem protection (CMER, 2010), coastal protection and restoration (LACPR, 2009), natural resource management (water, land and soil), species conservation especially, fish conservation from overfishing (FOS, 2007) and climate change (DFG, 2010). In addition, some other examples follow:

• In 2006-2007, FOS worked with The National Fish and Wildlife Foundation (NFWF) to develop an evaluation system help NFWF gauge impact across the various coral reef habitat and species conservation projects;
• In 2007, FOS worked with the Ocean Conservancy (OC) to evaluate the effectiveness of this Scorecard in helping to end overfishing in domestic fisheries.
• Between 1999-2004, FOS worked for WWF’s Asian Rhino and Elephant Action Strategy (AREAS) Program to ensure that Asian elephants and rhinos thrive in secure habitats within their historical range and in harmony with people.
• The Department of Fish and Game (DFG) is developing and implementing adaptation strategies to help protect, restore and manage fish and wildlife, with the understanding that some level of climate change will occur and that it will have profound effects on ecosystems in the United States.
• The Adaptive Management program was created by CMR to provide science-based recommendations and technical information to assist the Forest Practices Board. In April 2010, the Forest Practices Adaptive Management Annual Science Conference was held in Washington.
• In 2009, The Louisiana Coastal Protection and Restoration (LACPR) Technical Report has been developed by the United States Army Corps of Engineers (USACE) according to adaptive management process.
• Since 2009, the Kenya Wildlife Service has been managing its marine protected areas using adaptive management in an ongoing process of learning through the Science for Active Management (SAM) Program.

Use in other practices as a tool for sustainability

Adaptive management as a systematic process for improving environmental management policies and practices is the traditional application however, the adaptive management framework can also be applied to other sectors seeking sustainability solutions such as business and community development. Adaptive management as a strategy emphasizes the need to change with the environment and to learn from doing. Adaptive management applied to ecosystems makes overt sense when considering ever changing environmental conditions. The flexibility and constant learning of an adaptive management approach is also a logical application for organizations seeking sustainability methodologies. Businesses pursuing sustainability strategies would employ an adaptive management framework to ensure that the organization is prepared for the unexpected and geared for change. By applying an adaptive management approach the business begins to function as an integrated system adjusting and learning from a multi-faceted network of influences not just environmental but also, economic and social (Dunphy, Griffths, & Benn, 2007). The goal of any sustainable organization guided by adaptive management principals must be to engage in active learning to direct change towards sustainability (Verine, 2008). This “learning to manage by managing to learn” (Bormann BT, 1993) will be at the core of a sustainable business strategy.

Sustainable community development requires recognition of the relationship between environment, economics and social instruments within the community. An adaptive management approach to creating sustainable community policy and practice also emphasizes the connection and confluence of those elements. Looking into the cultural mechanisms which contribute to a community value system often highlights the parallel to adaptive management practices, “with [an] emphasis on feedback learning, and its treatment of uncertainty and unpredictability”(Berkes, Colding, & Folke, 2000). Often this is the result of indigenous knowledge and historical decisions of societies deeply rooted in ecological practices (Berkes, Colding, & Folke, 2000). By applying an adaptive management approach to community development the resulting systems can develop built in sustainable practice as explained by the Environmental Advisory Council (2002), “active adaptive management views policy as a set of experiments designed to reveal processes that build or sustain resilience. It requires, and facilitates, a social context with flexible and open institutions and multi-level governance systems that allow for learning and increase adaptive capacity without foreclosing future development options” ( p. 1121).

In an ever-changing world, adaptive management appeals to many practices seeking sustainable solutions by offering a framework for decision making that proposes to support a sustainable future which, “conserves and nurtures the diversity — of species, of human opportunity, of learning institutions and of economic options”(The Environmental Advisory Council, 2002, p. 1121).

Effectiveness of adaptive management

It is difficult to test the effectiveness of adaptive management in comparison to other management approaches. One challenge is that once a system is managed using one approach it is difficult to determine how another approach would have performed in exactly the same situation. One study tested the effectiveness of formal passive adaptive management in comparison to human intuition by having natural resource management students make decisions about how to harvest a hypothetical fish population in an online computer game. The students on average performed poorly in comparison to the computer programs implementing passive adaptive management.
