ADDITIONAL INFORMATION (needs to be migrated using the "edit with form" link)

Scope of the system

The schema of LEaRNForME

A procedure has been conceived and implemented in order to support the forester in classifying each homogeneous land unit for:

  • predisposition to instability phenomena (termed "propensity") such as shallow landslides, water erosion and runoff generation;
  • vegetation cover functionality in contrasting these events.

Both aspects have to be described and modelled by means of distinctive sets of variables; neural network analysis is then applied to a comprehensive set of study cases. The resulting evaluations of predisposition and functionality are combined into four different indexes with descriptive and planning significance:

  • equilibrium level, a rough estimation of the balance between tendency and cover protection;
  • protection value, assessment of the ability of the vegetation in controlling land degradation;
  • constraint level, grade of limitation with respect to timber-oriented management compatible with the assessed protection value;
  • action priority, preliminary screening of land units requiring ameliorative practices.

At present only the models devoted to the protection from shallow landslides and soil water erosion are operating; analogous procedure for runoff generation is in progress. To try the online-models go to this Web page: http://www.isafa.it/scientifica/assestamento/riselvitalia43/modelli_eng.htm/.

System origin

LEaRNForME was developed during 2001-2007 by Gianfranco Scrinzi, David Galvagni and Giacomo Colle in the Forest Monitoring and Management Unit (Unità di ricerca per il Monitoraggio e la Pianificazione forestale) (http://mpf.entecra.it/) of Italian Council for Research in Agriculture (Consiglio per la Ricerca e la Sperimentazione in Agricoltura) (http://sito.entecra.it).

Support for specific issues

LEaRNForME assists the forestry on site where shallow landslide, water erosion and runoff generation are instability phenomena.

Support for specific thematic areas of a problem type

  • Forest planning.
  • Territorial planning.
  • Protection.
  • Prevention.

Capability to support decision making phases

  • Intelligence: the system use a fully automatic, congruent, progressive and recordable procedure.
  • Design: forest planner input data to evaluate propensity and protective functionality of forest.
  • Choice: results give operational and descriptive indexes for sustainable management.
  • Monitor: implemented for test areas.

Data and data models

Typical spatial extent of application

The typical spatial extent of application is the forest management plan. There isn’t a base spatial unit for the output, it’s depend on what extension data input refer. But the minimum reasonable unit is the forest plot. Definitely we can say that the typical spatial extent of application is the single property scale.

Forest data input

The forest data input are about vegetation cover and forest management disturbances.

Type of information input from user (via GUI)

The user provides basic input data about the site conditions (lithology, aspect, slope, vegetation cover, erodibility, land use, practices, disturbances, etc.). In the shallow landslides model, the users input data to evaluate propensity to instability phenomena concerning: lithology, strata bedding, aspect, slope, climatic aggressiveness, drained area and seismicity. To evaluate vegetation cover protective functionality, the user input data about category of vegetation types, vegetation types, dominating vegetation cover, cover gaps, secondary vegetation cover, forest management disturbances, other disturbances, forest engineering practices, forest engineering practices. In the soil water erosion model the user input data to evaluate the propensity to instability phenomena concerning erodibility, climatic aggressiveness, heat load index, topographic factor. To evaluate vegetation cover protective functionality, the user input data concerning land use categories, land use, dominating vegetational cover, bushes cover, grasses cover, dead materials cover, agro-forest management disturbances, practices, slope.


Models

The system use Artificial Neural Network (ANN) models.

Forest models

Social models

Decision Support

Definition of management interventions

The shallow landslides form
The soil water erosion form

The intersection of the vegetation functionality and land propensity to an instability phenomenon through complex mathematical functions gives four useful indices for soil conservation purposes. The user has to interpret this following indices.

  • equilibrium level: this index provides a rough estimation of the balance between land tendency to the analysed geomorphologic phenomenon and cover protection. The “balanced” situation corresponds to conditions of almost equivalent levels of Propensity and Functionality; in these cases one can suppose that the protective action of the vegetation cover is adequate to face the onset of the degradation phenomena under examination. When the warrant provided by the vegetation increases the situation may be classified as “quiet”. On the opposite, the increase of Propensity generates a more or less unbalanced situation which may be defined as “uncertain” or “worrying” according to the algebraic difference between the two indexes;
  • protection value: it assesses the ability of the vegetation in controlling land degradation. The protection value is classified into three classes (“high”, “fair” and “negligible”) according to a set of sigmoid functions;
  • constraint level: this index expresses the degree of limitation with respect to timber-oriented management in relation to the assessed protection value. The classes of constraint are three: “none or negligible”, allowing the adoption of even very intensive cultural systems; “intermediate”, in which only cutting and harvesting techniques that assure the integrity of root apparatus and soil should be allowed; “maximum”, where only cares devoted to the enhancement of the protective functionality of the vegetation cover should be permitted (woodlands destined primarily to the environmental protection);
  • action priority: this index assumes some planning importance by representing a preliminary screening of land units requiring ameliorative practices both for increasing the vegetation cover and for runoff control. The conceptual approach is addressed to prevent the degradation phenomena rather then to reclaim compromised situations. The model provides three classes of “action priority” (“high”, “intermediate” and “negligible”).

Typical temporal scale of application

Planning and operational level.

Types of decisions supported

  • Management and sylvicoltural actions.
  • Strategic decisions.
  • Operating control decisions.

Decision-making processes and models

Output

Types of outputs

The outputs of LEaRNForME Web system are qualitative indices. The outputs of LEaRNForME in stand-alone system are maps and table.

Spatial analysis capabilities

LEaRNForME in stand-alone system integrates weighted overlay capabilities using GIS functions.

Abilities to address interdisciplinary, multi-scaled, and political issues

System

System requirements

The Web application runs on multiplatform environment, only an Internet access and a Web browser is required. The stand-alone application requires ArcView 3.x and MS Access.

Architecture and major DSS components

LEaRNForME is both a stand-alone and a Web application. LEaRNForME is a modular system.

Usage

Forest management and planning, educational.

Computational limitations

No limitations for the Web application; in the stand-alone GIS application it depends on hardware and software used.

User interface

The user has to fill the tables for each instability phenomena: in some case he has to select between the proposed values in the pull down menu. It’s not necessary specific computer knowledge for using the system, but geological and forestry comptences is required to choose the appropriate classes for each variable.

Documentation and support

Information about LEaRNForME can be found at the Ri.Selv.Italia project website.

Installation

Installation not needed.
