La gestión de recursos naturales es intrínsecamente compleja. Implica ciclos ecológicos, hidrológicos, clima, animales, plantas y geografía, etc. Todos ellos son dinámicos y están interrelacionados. Un cambio en uno de ellos puede tener impactos de largo alcance o largo plazo, algunos incluso irreversibles. La gestión de estos recursos debe tener en cuenta, además de los sistemas naturales, a los diferentes actores y sus intereses, sus políticas, cuestiones políticas, fronteras geográficas, implicaciones económicas y demás. Es muy difícil satisfacer todos los aspectos a la vez. Esto resulta en situaciones conflictivas.
Después de la Conferencia de las Naciones Unidas para el Medio Ambiente y el Desarrollo (UNCED") por sus siglas en inglés) celebrada en Río de Janeiro en 1992, la mayoría de los países suscribieron nuevos principios para la gestión integrada de tierra, agua, y bosques. A pesar de que los nombres de los programas varían de país a país, todos expresan objetivos similares.
Los diferentes planteamientos aplicados a la gestión de recursos naturales incluyen:.
• - Enfoque de arriba abajo (ordeno y mando).
• - Gestión comunitaria.
• - Gestión adaptativa.
• - Principio de precaución.
• - Gestión integrada.
Community-based management (CBNRM), also called "social resource management,"[3] combines conservation objectives with the generation of economic benefits for rural communities. The 3 key assumptions are: locals are in a better position to conserve natural resources, people will conserve a resource only if the benefits exceed the costs of conservation, and people will conserve a resource that is directly linked to their quality of life.[6] When the quality of life of locals is reinforced, their effort and commitment to ensure that the resource will continue to be available in the future in equal quantity and quality is also highlighted.[23] Regional and community-based management of natural resources is also based on the principle of subsidiarity.
The United Nations advocates CBNRM in the Convention on Biodiversity and the Convention to Combat Desertification. However, the decentralized management of these resources can result in an ambiguous legal and social environment in which local communities rapidly and unsustainably exploit resources for fear that this environment will change and they will no longer be able to do so. An example is the forest populations in central Kalimantan (Indonesia).[24] To avoid this the environment must be clearly defined.
A problem of the CBNRM is to reconcile and harmonize the objectives of socioeconomic development, protection of biodiversity and sustainable use of resources.[25] The competing interests show how the motives behind participation differ into: people-centered (active or participatory results that give authentic power to the population) and planner-centered (the population is only a passive recipient of the results).[26][27][28] Understanding power relations is fundamental to the success of the CBNRM. Locals may be reluctant to defy government recommendations for fear of losing promised benefits.
CBNRM is particularly advocated by NGOs working with local communities and groups, on the one hand, and by national and transnational organizations, on the other hand. They thus build and expand new versions of environmental and social activism that link social justice and environmental agendas with the direct and indirect benefits of resource exploitation, including income sharing, employment, economic diversification and promotion of identity and pride of locals.[29] The ecological and social successes and failures of the CBNRM have been documented.[30][31] The CBNRM poses new challenges because it introduces the concepts of community, territory, indigenous and conservation in politically varied plans and programs in various places. Warner and Jones discuss strategies to effectively manage conflicts in the CBNRM.[32].
The ability of indigenous communities to conserve natural resources has been recognized by the Australian Government with the Caring for Our Country program.[33] The Ministry (in Australia they are called departments) of Agriculture, Fisheries and Forestry, and the Ministry of Environment, Water, Heritage and the Arts, jointly administer this program. They share responsibility for government sustainable agriculture and environmental programs, which have traditionally and generally been called "natural resource management." These programs have been processed regionally, through 56 local governments, successfully allowing regional communities to decide priorities in the management of their resources.[34].
More broadly, a study in Tanzania and the Pacific investigated what motivates communities to adopt CBNRM, and found that it is adopted by aspects of the specific program and by the socio-ecological context.[35] Overall the adoption of these programs appears to reflect the relative advantage and access to external technical assistance they provide to locals.[35] There has been socioeconomic criticism of CBNRM in Africa, but its ecological effectiveness, as measured by population densities of fauna and flora, has been repeatedly demonstrated in Africa. Tanzania.[36][37][38].
Governance is considered key to carrying out community or region-based natural resource management. In the Australian state of New South Wales, the 13 river basin management companies (CMAs) are overseen by the Natural Resources Commission (NRC), responsible for auditing the effectiveness of regional resource management programs.[39].
Adaptive management
The primary methodological approach of Australian river basin managers to manage regional natural resources is adaptive management.[7].
This view recognizes that adaptation occurs through a “plan-execute-check-act” process. It also recognizes 7 key components that should be considered in the practice of proper natural resource management:.
• - Determination of the scale.
• - Collection and use of knowledge.
• - Information management.
• - Control and evaluation.
• - Risk management.
• - Community commitment.
• - Collaboration opportunities.[7].
Integrated management of natural resources
Known as INRM, integrated natural resource management is a process that systematically manages these resources, including multiple aspects of resource use (biophysical, sociopolitical and economic), meeting the production objectives of producers and other direct users (e.g. food security, profitability or risk aversion) as well as broader community objectives (e.g. poverty reduction, well-being of future generations or environmental conservation). The INRM focuses on sustainability and at the same time tries to incorporate all possible parties from the same planning level, reducing possible future conflicts. The conceptual basis of INRM has evolved in recent years through the convergence of research in various areas such as sustainable land use, participatory planning, integrated watershed management and adaptive management.[40][41][41] INRM is being used extensively and successfully in community and regional natural resource management.[42].
