释义 |
Natural resource management refers to the management of natural resources such as land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations (stewardship). Natural resource management deals with managing the way in which people and natural landscapes interact. It brings together land use planning, water management, biodiversity conservation, and the future sustainability of industries like agriculture, mining, tourism, fisheries and forestry. It recognises that people and their livelihoods rely on the health and productivity of our landscapes, and their actions as stewards of the land play a critical role in maintaining this health and productivity.[1] Natural resource management specifically focuses on a scientific and technical understanding of resources and ecology and the life-supporting capacity of those resources.[2] Environmental management is also similar to natural resource management. In academic contexts, the sociology of natural resources is closely related to, but distinct from, natural resource management. HistoryThe emphasis on sustainability can be traced back to early attempts to understand the ecological nature of North American rangelands in the late 19th century, and the resource conservation movement of the same time.[3][4] This type of analysis coalesced in the 20th century with recognition that preservationist conservation strategies had not been effective in halting the decline of natural resources. A more integrated approach was implemented recognising the intertwined social, cultural, economic and political aspects of resource management.[5] A more holistic, national and even global form evolved, from the Brundtland Commission and the advocacy of sustainable development. In 2005 the government of New South Wales, established a Standard for Quality Natural Resource Management,[6] to improve the consistency of practice, based on an adaptive management approach. In the United States, the most active areas of natural resource management are wildlife management often associated with ecotourism and rangeland management. In Australia, water sharing, such as the Murray Darling Basin Plan and catchment management are also significant. Ownership regimesNatural resource management approaches can be categorised according to the kind and right of stakeholders, natural resources:
Stakeholder analysisStakeholder analysis originated from business management practices and has been incorporated into natural resource management in ever growing popularity. Stakeholder analysis in the context of natural resource management identifies distinctive interest groups affected in the utilisation and conservation of natural resources.[8]There is no definitive definition of a stakeholder as illustrated in the table below. Especially in natural resource management as it is difficult to determine who has a stake and this will differ according to each potential stakeholder.[9] Different approaches to who is a stakeholder:[9]
Therefore, it is dependent upon the circumstances of the stakeholders involved with natural resource as to which definition and subsequent theory is utilised. Billgrena and Holme[9] identified the aims of stakeholder analysis in natural resource management:
This gives transparency and clarity to policy making allowing stakeholders to recognise conflicts of interest and facilitate resolutions.[9][17] There are numerous stakeholder theories such as Mitchell et al.[18] however Grimble[17] created a framework of stages for a Stakeholder Analysis in natural resource management. Grimble[17] designed this framework to ensure that the analysis is specific to the essential aspects of natural resource management. Stages in Stakeholder analysis:[17]
Grimble and Wellard[13] established that Stakeholder analysis in natural resource management is most relevant where issued can be characterised as;
In the case of the Bwindi Impenetrable National Park, a comprehensive stakeholder analysis would have been relevant and the Batwa people would have potentially been acknowledged as stakeholders preventing the loss of people's livelihoods and loss of life.[13][17] Nepal, Indonesia and Koreas' community forestry are successful examples of how stakeholder analysis can be incorporated into the management of natural resources. This allowed the stakeholders to identify their needs and level of involvement with the forests. Criticisms:
Management of the resourcesNatural resource management issues are inherently complex. They involve the ecological cycles, hydrological cycles, climate, animals, plants and geography, etc. All these are dynamic and inter-related. A change in one of them may have far reaching and/or long term impacts which may even be irreversible. In addition to the natural systems, natural resource management also has to manage various stakeholders and their interests, policies, politics, geographical boundaries, economic implications and the list goes on. It is a very difficult to satisfy all aspects at the same time. This results in conflicting situations. After the United Nations Conference for the Environment and Development (UNCED) held in Rio de Janeiro in 1992, most nations subscribed to new principles for the integrated management of land, water, and forests. Although program names vary from nation to nation, all express similar aims. The various approaches applied to natural resource management include:
Community-based natural resource managementThe community-based natural resource management (CBNRM) approach combines conservation objectives with the generation of economic benefits for rural communities. The three key assumptions being that: locals are better placed to conserve natural resources, people will conserve a resource only if benefits exceed the costs of conservation, and people will conserve a resource that is linked directly to their quality of life.[5] When a local people's quality of life is enhanced, their efforts and commitment to ensure the future well-being of the resource are also enhanced.[22] Regional and community based natural resource management is also based on the principle of subsidiarity. The United Nations advocates CBNRM in the Convention on Biodiversity and the Convention to Combat Desertification. Unless clearly defined, decentralised NRM can result an ambiguous socio-legal environment with local communities racing to exploit natural resources while they can e.g. forest communities in central Kalimantan (Indonesia).[23] A problem of CBNRM is the difficulty of reconciling and harmonising the objectives of socioeconomic development, biodiversity protection and sustainable resource utilisation.[24] The concept and conflicting interests of CBNRM,[25][26] show how the motives behind the participation are differentiated as either people-centred (active or participatory results that are truly empowering)[27] or planner-centred (nominal and results in passive recipients). Understanding power relations is crucial to the success of community based NRM. Locals may be reluctant to challenge government recommendations for fear of losing promised benefits. CBNRM is based particularly on advocacy by nongovernmental organizations working with local groups and communities, on the one hand, and national and transnational organizations, on the other, to build and extend new versions of environmental and social advocacy that link social justice and environmental management agendas[28] with both direct and indirect benefits observed including a share of revenues, employment, diversification of livelihoods and increased pride and identity. Ecological and societal successes and failures of CBNRM projects have been documented.[29][30] CBNRM has raised new challenges, as concepts of community, territory, conservation, and indigenous are worked into politically varied plans and programs in disparate sites. Warner and Jones[31] address strategies for effectively managing conflict in CBNRM. The capacity of indigenous communities to conserve natural resources has been acknowledged by the Australian Government with the Caring for Country[32] Program. Caring for our Country is an Australian Government initiative jointly administered by the Australian Government Department of Agriculture, Fisheries and Forestry and the Department of the Environment, Water, Heritage and the Arts. These Departments share responsibility for delivery of the Australian Government's environment and sustainable agriculture programs, which have traditionally been broadly referred to under the banner of ‘natural resource management’. These programs have been delivered regionally, through 56 State government bodies, successfully allowing regional communities to decide the natural resource priorities for their regions.[33] More broadly, a research study based in Tanzania and the Pacific researched what motivates communities to adopt CBNRM's and found that aspects of the specific CBNRM program, of the community that has adopted the program, and of the broader social-ecological context together shape the why CBNRM's are adopted[34]. However, overall, program adoption seemed to mirror the relative advantage of CBNRM programs to local villagers and villager access to external technical assistance[34]. There have been socioeconomic critiques of CBNRM in Africa,[35] but ecological effectiveness of CBNRM measured by wildlife population densities has been shown repeatedly in Tanzania.[36][37] Governance is seen as a key consideration for delivering community-based or regional natural resource management. In the State of NSW, the 13 catchment management authorities (CMAs) are overseen by the Natural Resources Commission (NRC), responsible for undertaking audits of the effectiveness of regional natural resource management programs.[38] Adaptive managementThe primary methodological approach adopted by catchment management authorities (CMAs) for regional natural resource management in Australia is adaptive management.[6] This approach includes recognition that adaption occurs through a process of ‘plan-do-review-act’. It also recognises seven key components that should be considered for quality natural resource management practice:
Integrated natural resource managementIntegrated natural resource management (INRM) is a process of managing natural resources in a systematic way, which includes multiple aspects of natural resource use (biophysical, socio-political, and economic) meet production goals of producers and other direct users (e.g., food security, profitability, risk aversion) as well as goals of the wider community (e.g., poverty alleviation, welfare of future generations, environmental conservation). It focuses on sustainability and at the same time tries to incorporate all possible stakeholders from the planning level itself, reducing possible future conflicts. The conceptual basis of INRM has evolved in recent years through the convergence of research in diverse areas such as sustainable land use, participatory planning, integrated watershed management, and adaptive management.[39][40][40] INRM is being used extensively and been successful in regional and community based natural management.[41] Frameworks and modellingThere are various frameworks and computer models developed to assist natural resource management. Geographic Information Systems (GIS)GIS is a powerful analytical tool as it is capable of overlaying datasets to identify links. A bush regeneration scheme can be informed by the overlay of rainfall, cleared land and erosion.[42] In Australia, Metadata Directories such as NDAR provide data on Australian natural resources such as vegetation, fisheries, soils and water.[43] These are limited by the potential for subjective input and data manipulation. Natural Resources Management Audit FrameworksThe NSW Government in Australia has published an audit framework[44] for natural resource management, to assist the establishment of a performance audit role in the governance of regional natural resource management. This audit framework builds from other established audit methodologies, including performance audit, environmental audit and internal audit. Audits undertaken using this framework have provided confidence to stakeholders, identified areas for improvement and described policy expectations for the general public.[45][46] The Australian Government has established a framework for auditing greenhouse emissions and energy reporting, which closely follows Australian Standards for Assurance Engagements. The Australian Government is also currently preparing an audit framework for auditing water management, focussing on the implementation of the Murray Darling Basin Plan. Other elements
The issue of biodiversity conservation is regarded as an important element in natural resource management. What is biodiversity? Biodiversity is a comprehensive concept, which is a description of the extent of natural diversity. Gaston and Spicer[47] (p. 3) point out that biodiversity is "the variety of life" and relate to different kinds of "biodiversity organization". According to Gray[48] (p. 154), the first widespread use of the definition of biodiversity, was put forward by the United Nations in 1992, involving different aspects of biological diversity.
The "threats" wreaking havoc on biodiversity include; habitat fragmentation, putting a strain on the already stretched biological resources; forest deterioration and deforestation; the invasion of "alien species" and "climate change"[49]( p. 2). Since these threats have received increasing attention from environmentalists and the public, the precautionary management of biodiversity becomes an important part of natural resources management. According to Cooney, there are material measures to carry out precautionary management of biodiversity in natural resource management.
Cooney claims that the policy making is dependent on "evidences", relating to "high standard of proof", the forbidding of special "activities" and "information and monitoring requirements". Before making the policy of precaution, categorical evidence is needed. When the potential menace of "activities" is regarded as a critical and "irreversible" endangerment, these "activities" should be forbidden. For example, since explosives and toxicants will have serious consequences to endanger human and natural environment, the South Africa Marine Living Resources Act promulgated a series of policies on completely forbidding to "catch fish" by using explosives and toxicants.
According to Cooney, there are 4 methods to manage the precaution of biodiversity in natural resources management;
In order to have a sustainable environment, understanding and using appropriate management strategies is important. In terms of understanding, Young[50] emphasises some important points of land management:
Dale et al. (2000)[51] study has shown that there are five fundamental and helpful ecological principles for the land manager and people who need them. The ecological principles relate to time, place, species, disturbance and the landscape and they interact in many ways.It is suggested that land managers could follow these guidelines:
