ACTION 4

Development of basic modelling procedures to be applied to the GIS

The action uses both data and processing from actions 2 and 3 (i.e. weather monitoring data, hydropedological models) so as to develop a set of applied models to address specific "application themes". The main themes are: i) Environment and ii) Agriculture.

Action 4.1

Environmental themes (including climate change scenarios)

This action and the subsequent action 4.2 are conceived especially to develop the "engines" for the applied dynamic simulations. These simulations will be based on the outputs and data produced during the previous actions 2 and 3.  Below are listed the activities concluded or in progress within those scheduled for action 4.1:

Progress

Erosion susceptibility: this issue is addressed by the utilization of the well established RUSLE procedures (USDA), widely applied in the Italian landscape in evaluating the potential risk of soil erosion. RUSLE is basically an empirical multiplicative model which operates by overlaying input environmental data (i.e. climate data, landscape morphological data, etc.) to estimate the potential risk of soil erosion. In the SOILCONSWEB project the model uses as input data the information already stored in the SID (see actions 2). In addition, climate data if required could be obtained in real time and collected from the clime system already developed specifically for the project (see action 2.3) in order to obtain estimates about the effective rate of soil erosion.  The erosion model has been developed and integrated in the SDSS under a specific tool by which the user can query the system about the risk of soil erosion over a specific area (see action 5.1)

Protective soil capability toward ground water pollution:the possibility to implement in the DSS parts of the CropSyst model (Stockle et al. 2003) to describe crop growth and the soil nitrogen cycle is currently under analysis, combiningthem with the hydrological part of the SWAP model, already utilized for the computation of  a soil water stress index (see action 3.1). The authors of the CropSyst  program (Prof. C. Stockle and Dr. R. Nelson from Washington State University) have agreed to share the program code with the experts involved in the SOILCONSWEB project and to support them on model applications. Primarily the code must be recompiled from C++ to Unix language. The choice of the CropSyst model is due to its ability to simulate several annual and tree crops like vine with a simple, but functional, description of soil carbon and nitrogen cycles.

Disadvantaged areas: this issue is planned to be addressed using two approaches. The first one is already completed, it consists in the classification of the Valle Telesina into areas defined as "disadvantaged" according to  the Directive 75/268/EEC. The map of disadvantaged areas will shortly be integrated in the SDSS through a tool by which the users may query the system about the type of disadvantage in which their area of interest falls. The second approach is under development and will soon be ready. It will consist in a landscape classification based on disadvantages of a physical nature (i.e. slope, soil thickness, altitude, etc.)
Soil consumption: this problem is treated through comparison between past and present data on urbanization. The tool implemented in the DSS is already working (see action 5.1); it is composed of three modules: i) the module on soil sealing which allows data to be obtained on the agricultural land area ceded to the urbanization from the 1950s to the present day; ii) the module on urban fragmentation designed for mapping the fragmentation rate in urban development; iii) the module on the evolution of urban fragmentation that allows the evolution of fragmentation over time to be calculated in a specified area; This modules are structured in two main sections, analysis based on municipal scale and analysis based on self-user delimitated area of interest.

Soil suitability: the project structure involves the construction of some applications or tools concerning the theme "soil suitability". At the moment is already available the soil suitability map for spreading of oil mill wastes in Valle Telesina. The map has been realised within the project activities. It could be displayed and queried by means of a specific tool.

Action 4.2

Agricultural themes (environment-related)

This action was performed especially to enable the DSS to deal with specific queries for receiving practical information to support crop selection and cultivation management. The results of this specific sub-action will enable us to assess: land suitability for a specific crop (e.g. definition of various crop suitability microzones) and management (data collection, potential pathogens, use of fertilizers, etc.), the land classification of areas with high potential (application of geographical indications and designations of origin), the best farm management practices required with respect to the system of conditionality, etc.
As for action 4.1, the activities will be based on the outputs and data produced during actions 2 and 3.
Below are listed the activities already concluded

Progress

Activities on environmental issues: these issues are addressed by means of a tool developed in the DSS thought to provide several information and data about environmental characteristics. This tool includes modelling application (SWAP runs) and calculation instruments (on the fly operations) able to provide for example:

  • reports containing general information on environmental characteristics (including updated weather data) of a user specified area of interest;
  • tables containing data about the land use changes over time, within an area of interest selected by the user;
  • tables and maps containing information about the "actual soil water content", within an area of interest as above. This application works using SWAP model simulations also.

Activity on viticulture: Here we have tools dealing with "planning" and "management" stage.
With reference to the Planning stage, information, environmental data and elaborations have already been implemented in the DSS. Below follows a  list showing old and new tolls developed

  • Microzoning based on temperatures (Winkler Index): The index is mapped over the Valle Telesina area and may be displayed by the users through a specific tool. The users may know in which areas the index reaches the highest or lowest values.
  • Microzoning based on solar radiation : These maps are used in the DSS through a tool by which the users may visualize and examine them in order to recognize the best areas of Valle Telesina in terms of solar radiation. Soil stress index : The map is  implemented in the SID and queryable through a specific tool.
  • Terroir characterization : the DSS  tool called "Etichetta Terroir" (terroir label) has been developed. Soil suitability: about this issue we have produced a soil suitability map using as target of our research the main rootstocks used in the Valle Telesina. The user can visualize a map within his area of interest showing the soils classified according to their suitability in "hosting" the different rootstocks.
  • Viticultural Zoning: this is a new thematic layer produced within the project activities. The Valle Telesina has been "zoned" in GIS environment, according to several landscape physical factors and bioclimatic indices. We identified some thousands of polygons, each of which characterized by unique combination (values) of the above factors and indices.

Mapping the risk of phytopathies: this is a new thematic layer produced within the project activities. At the moment we mapped the Branas index as indicator for the risk of presence of "grapevine downy mildew disease". It is a static map identifying the areas more susceptible to the presence of that disease in Valle Telesina. The user can draw the area of interest and visualize the risk level. Future activities include the realization of a powdery mildew risk map also.

With reference to the Management stage, below follows a  list showing the new applications already working in the DSS:

  • Climatic conditions: this application has been intended to give the user the possibility to visualize the weather conditions (rain, temperature and solar radiation) by means of maps and graphs within the area of interest (previously designed). The application was developed thanks to the program described in action 2.3. It produces and stores distributed climatic data usable for this application.
  • Trend of production parameters: this application has been developed with the aim to visualize maps and graphs referred to several grape production parameters (i.e. the sugar levels, the acidity levels, the soil water stress levels, etc. ). The user can draws an area of interest and query the DSS to produce a map or a graph according to selected parameter. It is also implemented a simplified system capable to give for some parameters an estimate of future trends.
  • Disease: this application is based on the implementation within the DSS of one or several phytopatological models. With this application the user can draw an area of interest and query the system to produce (for a specified past period) the risk analysis on the development of downy mildew symptoms. The system works producing maps and graphs specifying the infection level. At the time the analysis is based on the past weather data (2010), but after the validation phase we expect to apply the model using data up to the last 24-48 hours;

Activity on olive growing: olive production represents the second most common agricultural activity in Valle Telesina landscale. The final objective is to develop a tool to characterize this agricultural activity as done for the viticulture. The user can draws an area of interest and query the DSS to produce several information, maps and graphs similarly as for the viticultural tools.

Activity on land suitability: the DSS will contain a module for the application of land suitability approaches in order to define the suitability of the soils and the environment in the Valle Telesina for the cultivation of other crops. Still to be produced.

Activity in forestry:
The tools is already working in the DSS. The structure is similar to that developed for the viticulture and olive growing. The user can query the system (within an area of interest) to produce reports and maps according to several environmental indices, production factors (i.e above ground biomass)  and management factors.
