Landscape Changes in the Mullica River Basin of the Pinelands National Reserve,New Jersey,USA

In 1979, the Pinelands Commission was established as a regional land-use planning and regulatory agency charged with the implementation of a Comprehensive Management Plan (CMP) for the Pinelands National Reserve (New Jersey, USA). The CMP was created to balance land preservation and development interests in the Reserve. Because water-quality degradation from developed and agricultural landscapes is associated with changes in the composition of biological communities, monitoring landscape changes provides one of the most direct measures of the impact of land-use policies on the Pinelands ecosystem. In this study, we prepared detailed, land-cover maps within randomly selected aerial-photograph plots for a major watershed in the Reserve. We used these land-cover maps to quantify changes in landscape composition and structure (i.e., patch size, patch area, and number of patches) and characterize land-cover transitions in the basin between 1979 and 1991. Because the study period represented the first 12 years of the regional-planning effort in the Reserve, we evaluated the relationship between land-cover transitions and Commission management-area designations which permit different land-use intensities. Although the landscape composition was similar in 1979 and 1991, we found an increase in the total area and number of developed-land, managed-grassland, and barren-land patches. An increase in the number of patches and a decrease in the total area and median and third-quartile patch sizes for forest land and for all patches regardless of cover type indicated that fragmentation of forest land and the landscape as a whole occurred during the study period. The major land-cover transitions that occurred during the period were the loss of forest land to development and associated cover types and the conversion of one agricultural type to another. Overall, land-cover transitions during the period were found to be consistent with the Commission management-area designations, which indicated that the regional-planning effort has been successful in directing human activities to appropriate areas of the basin.     

Saint Lucia's experience with formulating a national sustainable development strategy

In response to domestic development challenges and calls from the international community for countries to develop and begin the implementation of national sustainable development strategies by 2005, the Government of Saint Lucia initiated a project named Integrated Planning for Sustainable National Development in 2002. Under this initiative, it was intended to articulate a vision for the country's development and use this as the basis for identifying a set of development imperatives through a process that will superimpose identified national development goals and targets on the international sustainable development agenda to arrive at a national strategy and plan for sustainable development. The plan also called for institutional and structural adjustments to move the country away from current sectoral‐based development planning to an environment of dialogue, cooperation and collaboration among development partners in the articulation of development policies, plans and projects. The initiative did not evolve as planned mainly due to inadequate political and financial support and the inability of key institutions to see the bigger picture this initiative tried to paint for the nation.     

THE WESTERN WATER COMMISSION: WATERSHED MANAGEMENT RECEIVES THE AVI'ENTION OF A NEW GENERATION1

ABSTRACT: Our nation periodically reviews national water policy and considers its directions for the future. The most recent examination was directed at the western United States and the role of the federal agencies in meeting its needs. The West is no longer the frontier, but rather contains vibrant cities and booming centers of international trade, as well as tourism, mineral, and oil and gas development, agricultural, and other development. In this changing environment, federal water policies need to consider the long term sustainability of the West, provide justice to Indian tribes, protect the rivers and ecosystems on which natural systems depend, balance the needs of newcomers with those of agricultural users and communities, and meet a myriad of other demands. The Western Water Policy Review Advisory Commission has just concluded its review of these issues and issued its report. Key among the recommendations is the need to coordinate federal agencies at the basin and watershed level and make government more responsive to local needs, but within a framework that includes national mandates. The Commission's recommendations are presented here, along with some of the issues that surrounded the operations of the Commission.     

FOREST COVER,IMPERVIOUS‐SURFACE AREA,AND THE MITIGATION OF STORMWATER IMPACTS1

ABSTRACT: For 20 years, King County, Washington, has implemented progressively more demanding structural and nonstructural strategies in an attempt to protect aquatic resources and declining salmon populations from the cumulative effects of urbanization. This history holds lessons for planners, engineers, and resource managers throughout other urbanizing regions. Detention ponds, even with increasingly restrictive designs, have still proven inadequate to prevent channel erosion. Costly structural retrofits of urbanized watersheds can mitigate certain problems, such as flooding or erosion, but cannot restore the predevelopment flow regime or habitat conditions. Widespread conversion of forest to pasture or grass in rural areas, generally unregulated by most jurisdictions, degrades aquatic systems even when watershed imperviousness remains low. Preservation of aquatic resources in developing areas will require integrated mitigation, which must including impervious‐surface limits, forest‐retention policies, stormwater detention, riparian‐buffer maintenance, and protection of wetlands and unstable slopes. New management goals are needed for those watersheds whose existing development precludes significant ecosystem recovery; the same goals cannot be achieved in both developed and undeveloped watersheds.     

Effect of public opinion on national park planning in Turkey: A case study

National park plans are mainly prepared by a central planning team of the National Parks of Turkey. In this article, a model is presented that proposes a different approach to preparing national park plans. The study is based on a questionnaire distributed among the residents of the villages just outside a selected national park in Turkey and the relevant local and general authorities who are interested in the national park in their region, to find out the effect of public opinion on national park planning. Four basic strategies that represent the four main alternative approaches to forming policies in the planning of the park were identified. Respondents were asked to choose one and to suggest their own ideas. As this is a first attempt of such a study in Turkey, the results of the survey have been very encouraging. Therefore, this paper suggests that the assessment of public opinion should be borne in mind throughout the planning process in Turkey.     

Evaluating U.S. National Heritage Areas: Theory, Methods, and Application

Like many governmental actors in recent decades, the U.S. National Park Service (NPS) has operated increasingly through partnerships with other state and federal agencies, non-governmental organizations (NGOs), community groups, and private sector corporations. Perhaps the most salient example of this trend toward partnerships is the rapid growth and development of national heritage areas (NHAs). Since the first NHA received congressional designation in 1984, NHAs have become an increasingly popular strategy for protecting and managing landscapes. To date, congressional designation has been granted to 49 NHAs, making them one of the fastest growing initiatives involving the NPS. Despite this growth, no prior research has examined the efficacy or effectiveness of the NHA model. This article introduces the NHA concept, while reviewing the literature on evaluation research and its application to protected area management. We then offer an NHA program theory model for evaluating NHAs. The model was developed using a theory-based, process evaluation approach, along with 90 qualitative interviews conducted at three study sites: Blackstone River Valley National Heritage Corridor, MA-RI (BLAC); Delaware and Lehigh National Heritage Corridor, PA (DELE); and Cane River National Heritage Area, LA (CANE). We conclude by discussing the key challenges and implications associated with developing a long-term research agenda for evaluating NHAs.     

PLANNING FOR DROUGHT: THE ROLE OF STATE GOVERNMENT1

ABSTRACT: Although droughts are a frequent occurrence over much of the United States, response by state and federal government has been ineffective and poorly coordinated. Recently, several states have recognized the value of drought emergency planning and have developed plans to assist them in responding more effectively to prolonged periods of water shortage. These states have created an organizational structure to coordinate the assessment and response activities of state and federal agencies. Each state's drought response plan is unique since each state's water supply and management problems, and their consequent impacts, are unique. The drought response plans developed by Colorado, South Dakota and New York are reviewed here in detail. We recommend that other states affected by frequent and severe water shortages also develop drought emergency plans. These plans will enhance state government's ability to implement effective measures in a timely manner and, ultimately, may provide added incentive for the federal government to develop the national drought response plan called for by the General Accounting Office in 1979.     

Perceptions and attitudes of land managers in multi-tenure reserve networks and the implications for conservation

Multi-tenure reserve networks aim to connect areas managed for biodiversity conservation across public and private land and address the impacts of fragmentation on both biotic and social systems. The operation and function of Australian multi-tenure reserve networks as perceived by their land managers was investigated. Overall, the conservation of natural assets was the most frequently reported primary reason for involvement in a network. The perceived aims of the respective networks largely reflected the response identified for involvement and management. Over 88% of managers considered their involvement in multi-tenure reserve networks to be a positive or very positive experience. A lack of resources and time for management were considered major limitations of these networks. The majority (80%) of private land managers within networks were willing to be included in a national reserve system of conservation lands. As the Australian National Reserve System currently incorporates mostly public land, these findings have important and potentially positive implications for a greater role for protected private land.     

Assessing national sustainable development strategies: Strengthening the links to operational policy

At the Earth Summit in Rio de Janeiro in 1992, it was agreed that all countries should develop a national sustainable develop‐ment strategy (NSDS) as a key component of implementing the goals of Agenda 21. Progress has been limited. Few countries have established a formal strategy, and many of the strategies that exist have been only partially implemented. This article proposes an approach that addresses the need to improve existing strategic planning mechanisms. The approach is based on a periodic assessment of existing systems, to evaluate the extent to which they incorporate NSDS principles, and identify areas to be strengthened. The article describes an assessment methodology, presents examples of its use, and discusses ways in which current approaches to NSDS may be complemented by continual review and improvement of existing planning processes.     

Out of the wilderness? Achieving sustainable development within Scottish national parks

The introduction of national parks to Scotland represents a significant shift in the evolution of protected area management within the UK. Although the National Parks (Scotland) Act 2000 adopts the established national park aims of conservation and recreation, provisions are also made for advancing notions of sustainable development. This paper provides an assessment of the degree to which the Scottish national park model is likely to enable the realisation of multiple national park objectives. Five key areas are considered for analysis. These relate to management aims, institutional arrangements, implementation, democratic accountability and funding. The evaluation reveals that whilst management provisions have been established in accordance with international sustainable development guidelines, a number of concerns relating to operational processes remain.     

Understanding brownfields regeneration in the US

Federal, state and local initiatives have emerged in the United States over the last decade to address the increasing number of 'brownfield' properties that are perceived to be contaminated. These initiatives are based on the beliefs that the social and financial benefits provided by redevelopment exceed the costs imposed by the interventions and that the reuse of sites can further local sustainability objectives by reducing growth pressures in undeveloped areas. This paper provides an examination of the current state of the practice of brownfields within which these interventions should be based. We summarize brownfields problems and federal, state and local efforts to address these problems. We then present ten stylized propositions about brownfields and draw on a range of surveys of the public and private sectors and other sources to explore the reality behind these. Finally we use the propositions to tie brownfields regeneration to sustainable local development through an area wide approach to redevelopment rather than a site base approach which benefits a wider community or geographic area.     

Cross‐sectoral and participatory approaches to combating desertification: The Iranian experience

Anti‐desertification planning in Iran operates at the national level through the Five Year Development Plans, the National Plan to Combat Desertification — a long‐running scheme for which the Forest, Rangeland and Watershed Management Organisation (FRWO) is responsible — and the recently developed National Action Programme to Combat Desertification (the NAP). The Iranian NAP was formulated following the country's ratification of the United Nations Convention to Combat Desertification and drew heavily on the experience, expertise and collaboration of personnel in FRWO. Development and implementation of the NAP has had major policy impacts in Iran in the two main areas of generating cross‐sectoral cooperation between government instruments at the national planning level and by community participation in local projects to combat desertification. Documenting the evolution of cross‐sectoral and participatory approaches to desertification in Iran shows that the NAP provided impetus towards a transformation of previous procedures, a policy impact that is continuing to generate change.     

Managing Public Forests: Understanding the Role of Collaborative Planning

/ As federal land management agencies such as the USDA Forest Service increasingly choose to implement collaborative methods of public participation, research is needed to evaluate the strengths and weaknesses of the technique, to identify barriers to effective implementation of collaborative processes, and to provide recommendations for increasing its effectiveness. This paper reports on the findings of two studies focused on the experiences of Forest Service employees and their external partners as they work to implement collaborative planning processes in national forest management. The studies show both similarities and differences between agency employees and their partners in terms of how they evaluate their collaborative experiences. The studies reveal that both Forest Service employees and external partners are supportive of collaborative planning and expect it to continue in the future, both see the trust and relationships built during the process as being its greatest benefit, and both see the Forest Service's organizational culture as the biggest barrier to effective collaborative efforts. The groups differed in terms of evaluating each other's motivation for participating in the process and in whether the process was a good use of time and resources, with external partners seeing it as too drawn out and expensive. The paper concludes with a discussion of the policy implications and changes necessary to increase the effectiveness of collaborative efforts within the Forest Service and other federal land management agencies.KEY WORDS: Public land management; Collaborative planning; National forests; Public participation     

An evaluation of resource inventory and monitoring program used in national forest planning

The National Forest Management Act (1976) specifies that multiresource inventories be conducted to provide baseline data for development and, later, monitoring of national forest management plans. This mandate entails the most ambitious and complex resource planning effort ever attempted. In this paper we evaluate the structure and use of current inventory-monitoring programs and recommend a framework for gathering data to improve national forest planning. Current national guidelines are general and provide only basic directions to forest-level planners. Forest inventories have traditionally concentrated on timber. Although these inventories are often well designed, the questions we are now asking about forest resources have outgrown these methods. Forest management is impeded by general confusion over definitions of resources and the interactions among them. We outline a simple classification scheme that centers on identification of basic ecosystem elements that can be readily measured. Furthermore, spatial and temporal scales must be considered in the design of inventory-monitoring programs. The concept of ecological indicators is reviewed, and caution is advised in their use. Inventory-monitoring programs should be goal-directed and based on as rigorous a statistical design as possible. We also review fundamental issues of variable selection, validation, and sampling bias. We conclude by developing a flexible inventory-monitoring program that is designed to provide information on individual characteristics of the environment, rather than being based on fixed definitions of resources.     

CHARACTERIZATION OF SURFACE WATER QUALITY ALONG A WATERSHED DISTURBANCE GRADIENT1

ABSTRACT. Characterizing ecological indicators such as water quality is necessary to effectively manage human-dominated systems such as the New Jersey Pinelands. Pinelands surface waters are naturally acidic and low in nutrients and other dissolved substances. Water quality for 14 Pinelands stream sites monitored by the U.S. Geological Survey was characterized in relation to land use. A gradient of increasing pH, specific conductance, and concentration of dissolved calcium, dissolved magnesium, total nitrite + nitrate-nitrogen, total ammonia-nitrogen, and total phosphorus was associated with a watershed disturbance gradient of increasing land use intensity and waste water flow. These two parallel gradients emphasized the significant effect that watershed disturbance can have on natural water chemistry in the Pinelands. The results of this study can be applied to planning and regulatory programs in the Pinelands.

The dilemma of flood control in the United States

In spite of increasing annual expenditures for flood control, losses from flooding continue to rise in the United States. This seeming contradiction arises from overdependence on federally supported structural solutions to flood problems. Nonstructural controls are initiated reluctantly at local levels of government because of constitutional questions, restrictions of local tax bases, lack of federal subsidies for nonstructural solutions, and the high costs of delineating flood hazard areas. The success of the National Flood Insurance Program is doubtful since only about five percent of the flood-prone communities in the United States have qualified for the regular program. Future reduction of flood losses is dependent upon increasing popular awareness of flood hazards and altering federal subsidy policies to reduce the impact of local land-use regulations.     

RATIONAL PROTECTION OF WATER RESOURCES IN COASTAL ZONES THROUGH PLANNED DEVELOPMENT1

ABSTRACT: A significant water-resources problem in Florida and other coastal states where the ground-water resources are threatened by salt-water intrusion or direct pollution from septic tanks, canals or marinas, is the almost explosive urban development of the limited coastal zone without or with only little water related planning. The reported study deals with the establishment of methods for identification of areas which are suitable for development and of areas where complete preservation or controlled and limited development should be encouraged. A methodology using data input available from such federal and state agencies as the USGS, the U. S. Weather Bureau, and the various State Geological Surveys is developed and brought on a graphic form that will guide the planning process and allow the urban planner even without a background in geohydrology or water-resources engineering to identify the problem areas.     

Environmental planning and management for the Assarawat highland region of south-western Saudi Arabia: the traditional versus the professional approach

The environmental planning and management of the Assarawat highlands of south-western Saudi Arabia are currently confronted by difficult problems. Deforestation is caused either by natural or intentional forces. Natural factors are limited to lightning fire and drought, while intentional forces include vandalism caused by the burning or cutting of preserved forests. Such vandalism continues despite the tremendous efforts of afforestation and preservation by several government agencies, especially the Ministry of Agriculture and Water, the National Commission for Wildlife Conservation and Development and by the municipalities of the cities and towns in the region. For centuries, local inhabitants of the Assarawat highlands have successfully established environmental planning and management strategies which balanced the settlements' growth and natural resource uses according to Islamic laws, and the tribal self-government of each settlement and tribal region. Following the establishment of the Kingdom of Saudi Arabia in 1932, the land management system started to change from tribal-based, where every tribe used to manage its local territory, to State authority. The creation of the State witnessed the unification of various fragmented tribes of Saudi Arabia into one government. This meant that environmental planning and management moved from local/regional towards a national control. This investigation proposes that the local/regional planning and management practised by the tribes could be viably utilized today. As in the past, the implementation of these practices could protect the natural environment of the locality and region and regularize their exploitation rationally, as long as vernacular people implement them. Today environmental planning and management need to be based on strategies of local requirements that enable the indigenous people to plan and manage the use of the resources.
