The regional contest

� In the Molise Region the vast area planning policy has always been lacking. The only tool for vast area planning is the Landscape Plan which had, and still has, a major role in regional planning. The drawing up of the regional landscape plans began in 1987 and concluded with the creation of eight plans through the regional laws No 24 of 1989.laws No 24 of 1989.

� The Code of Cultural and Landscape Heritage (2004) introduced a new planning tool for the protection of the landscape in Italy: the Regional Landscape Plan.

� In response to the new concept of landscape planning the Molise Region decided in 2010 commissioned the University of Molise’s L.a.co.s.t.a. laboratory to draw up the new Regional Landscape Plan.

Case study area

The case study area chosen to test the analysis methodology is the one of Low

Molise, including coastal and pre-coastal municipalities. Is one of the most important

landscape area of all the Molise Region.

This is an area that suffered a great number of territorial transformations.

Diachronic maps

The Actual State (A) starts with the present state of territorial planning above

municipal level and, therefore with the P.T.P.A.A.V. In particular it was decided to

take into consideration the “map of territorial qualities” which identifies the elements

present within the territory whose importance is such to have warranted their

localisation and selection, characterisation and appraisal by the design groups.

Diachronic maps

The Evolutional State (E) is described through a comparison between two

representations of the territory made forty years apart. The aim is to highlight the

main changes in land use within the region. The vegetation map of the Molise

region was created according to two temporal horizons/two different periods: the

post-Second World War period (indicative reference date: 1954) and the

beginning of the 1990s (indicative reference date: 1992).

Diachronic maps

The final is the Previsional State (P), created for reading the territorial data in

relation to the previsions indicated by the planning tools presently in force.

Conclusions• The methodology is now forecasting to integrate each system evaluation to

result a single assessment system.

• The next step will be to integrate assessments of the 5 systems to have

a map of the quality of the territory.

• The three landscape quality objectives will be identified in this grid using an

algorithm which will result as applicable to all the territory.

• The research is developing innovative spatial analysis methodology.

• This methodology aims to provide an important innovation in this research

field: in the stage just described the methodology want to "read" the territory in

terms of three time horizons. Then combine them in each of the identified

resource systems in order to give equal importance to all spatial data.

• The final result of this process will be a methodology for the reading and

analysis of the territory which can be applied to the entire region in order to

generate a regional landscape plan based on the same method of reading and

interpreting the all territorial data.

• The universality of this methodology will be one of the new plan’s major

strengths.
