Landscape planning
Landscape planning, a branch of landscape architecture, is a multidisciplinary field that analyzes, evaluates, and guides landscape change across area and time scales. It links scientific data with land-use regulations and spatial design, along with stakeholder goals to support how landscapes should develop and evolve. because landscapes function as social-ecological systems, landscape planners try to balance ecological integrity, cultural values, and human well being while dealing with pressure from urbanization and climate change and the amount of resources available to them.
Landscape planning typically follows a structured sequence, starting with goal development followed by landscape analysis, development and evaluation of alternatives, selecting the preferred options, implementation, and monitoring. The planning process follows long standing and established ecological planning methods which use landscape structure, function, change, and scale to diagnose current conditions and predict future scenarios and potential outcomes. Landscape planning was originally used in the context of non-urban land use, but it has evolved to be commonly used to address urban, peri-urban, and rural environments and treat them as interconnected systems instead of independent environments. The field has evolved because scientists now understand that most landscapes exist as urbanized social–ecological systems which result from ecological processes and cultural practices and economic activities and institutional frameworks.
Despite the practical importance of landscape planning, it is widely described as an under-theorized field. Compared to adjacent fields such as ecology or geography, relatively few journals explicitly address landscape planning theory. Landscape and Urban Planning is one of the only major journals dedicated to landscape planning and even it emphasizes practice more than theory, which contributes to a weak conceptual framework of the whole field. Landscape planning draws from ecology, sociology, economics, engineering, and design. While the interdisciplinary nature is essential to the practical application of landscape planning, it also means that landscape planning lacks a single shared theoretical tradition. Linked fields such as landscape sociology are themselves new fields and not fully defined, adding to theoretical and conceptual confusion. Earlier generations of landscape planners relied on theories such as general systems theory, hierarchy theory, and stability models, however, these frameworks appear less frequently in contemporary literature and are essentially replaced by applicational concepts, such as green infrastructure, ecosystem services, social equity, health, cultural values, and governance, which outpaced the developing of a consolidated theory and creates gaps between practice and concept. In addition, landscape planning has highly elaborate procedural models aren't consistently grounded in a unified theory of landscape planning. Scientific concepts from landscape ecology, such as connectivity, resilience, and multi functionality, are used intensively during the landscape analysis phase and far less during goal development, decision making, and monitoring phases, showing incomplete theoretical integration across the structured sequence landscape planning typically follows.
According to Erv Zube landscape planning is defined as an activity concerned with developing landscaping amongst competing land uses while protecting natural processes and significant cultural and natural resources. Park systems and greenways of the type designed by Frederick Law Olmsted are key examples of landscape planning. Landscape designers tend to work for clients who wish to commission construction work. Landscape planners analyze broad issues as well as project characteristics which constrain design projects.
Landscape planners may work on projects which are of broad geographical scope, concern many land uses or many clients or are implemented over a long period of time. As an example, the damage caused by unplanned mineral extraction was one of the early reasons for a public demand for landscape planning.
In Europe
wrote on the need for town squares for markets and specific implementations to make most use of the space. In North Europe this developed into the idea that residential squares should be planned around green spaces. The first space of this type was the Place des Vosges. Residential squares were also made in Britain and their planning developed into the idea of incorporating public open space. Frederick Law Olmsted gave momentum to this idea with his proposal for a park systems in Boston - the famous Emerald Necklace. Patrick Abercrombie took up this idea and incorporated it in his great 1943-4 Open Space Plan for the County of London. An example of landscape planning in use is the plans of RWE in the wake of its mining operations and how they plan to use leftover detritus and soil in their re-cultivation efforts to restore the damaged ecosystems and landscapes created by open pit mines.In the UK
Landscape planning in the United Kingdom evolved from early preservation and public amenity movements and has become an integral element in spatial and environmental planning. Conservation interests in the scenic and cultural value of the countryside during the late nineteenth and early twentieth centuries influenced the formation of bodies such as the National Trust in 1895 and contributed to general debates on the protection of "natural beauty," "cultural heritage," and access to open space. Early twentieth century planners, such as Patrick Abercrombie, advocated for systematic landscape surveys as a basis for regional plans, linking countryside conservation to urban growth management. After World War II, national parks and Areas of Outstanding Natural Beauty were formally established through the National Parks and Access to the Countryside Act 1949, as a statuary framework to protect valued landscapes across England and Wales. These early policy and landscape protection initiatives followed objectives in heritage and social welfare, and provided public enjoyment as well as preservation. The Countryside Act 1968, and the earlier Countryside Act 1967, pushed this approach to also cover countryside recreation, ecological conservation, and the planning of rural areas beyond designated areas of scenic quality. From the 1960s and 70s, the rise of environmental awareness and applied ecological approach influenced the practice of landscape planning. The development of ecological design, formed by works such as Ian McHarg's Design with Nature, and the emerging environment impact assessment procedures in the Environmental Assessment Regulations 1988 acts supported the inclusion of environmental science in planning processes. From the twentieth century onwards landscape character assessment became a widely adopted method for describing, classifying, and managing landscape types across the UK. This approach presented landscapes as a product of natural processes and cultural practices, supporting the view that all landscapes have distinct characteristics that should be considered in planning and policy.In the twenty first century, the European Landscape Convention reinforced these developments in landscape planning by treating landscape as a universal and changing phenomenon, not something specific to the countryside, extending planning responsibilities to Urban, peri-urban, and degraded areas as well as to traditionally protected countryside. UK government agencies, such as Natural England, NatureScot, and the Countryside Council for Wales, integrated the principles concerning environmental awareness and the universality of landscapes into national and regional frameworks that link together landscape character, biodiversity, and cultural identity with sustainable development and community participation. Modern landscape planning in the UK operates across the country's urban and rural landscapes, trying to balance conservational and developmental objectives while contributing to nation wide agendas of regeneration, climate adaptation, and sustainable land management.
