Interactive Micro Level Information System for sustainable wastelands development


Objective: Identification of the system dynamic model of land utilisation pattern in a naturally evolving undulating terrain by further determining the carrying capacity of each and parcel in various physiographic terrain situations.

Study Area: The total area under study is 1051.3 hectares. All the 10 mouzas are contiguous to each other and in all pratical sense closely define the mini micro watershed (KS 44) within the Kangsabati sub basin. The mouzas are (I) DHASRGAM-255 (ii) SIALPAHARI-256, (iii)DHABANI-257, (iv) SIMCHAKA - 258, (V) Saluka - 260, (vi) CHANDANPUR - 261, (vii) BENIABAID-262, (viii) BHEDUA - 264, (ix) LABDAPARA, (x) BIRKHAM -266.

Methodology: The set up included in Analytical Laboratory supported by Computer aided data inventory, analysis and programming for simulation model along with a field station at the project site in Khatra where physical surveys and regular data generation activities were organised.The methodology involved in implementing the project aspects were as follows:

(i) Development and processing of primary socio-economic, land use, edaphic, information with special reference to wastelands' formation and possible control measures; 

(ii) Development of system of dynamics model with reference to current land use and encroachment of land status, socio-economic status and inherent and/or imposed restrictions of land situation

(iii) Propose a prospective landuse and model validation through field trials and l linkages based on both physical implementation and simulation modeling. 

Research Achievement & outputs:
The project developed the system dynamic model of land utilisation pattern based on traditional human wisdom in a naturally evolving undulating terrain by further determining the carrying capacity of each land parcel in various physiographic terrain situations. Besides, a software Interface, SFR ECOLAND Ver. 1.01, 1997 was developed to act as decision support tool for the planners. The project specifically focussed on the following : 

* The project specifically aimed at generating an alternative land use model with emphasis on maximizing the economic gain for the community. The methodology of investigation suggested here can develop and update the interactive micro level information system and it was field tested for estimating the need for the development of a watershed situation on a long term basis and also various management options to achieve sustainable development through some specific interventions.

* This model can act as an interface for various decision support needs for the planners. Taking into consideration the various parameters of land use, water use, prospect of availability of water under the current generic condition and socio-economic demands, it can be said that this model can in no uncertain terms provide a definitive perspective for land based agro ecological systems, even under current population and demographic conditions on the prospect of attaining a sustainable development in respect of all forms of demands of the living community provided some positive willful management interventions are ensured.

* This PC based software version has 3 major components :

(a) Query based data input system on :

(i) Land use, (ii) Land classification, iii) Hydrology and Hydro-geology, (iv) Geology and geomorphology, (v) Drainage, slope, contours, (vi) Soil physics, (vii) Soil chemistry, (viii) Demography, (ix) Agriculture, crop pattern, (x) Industry (small scale industry), (xi) Bio diversity, (xii) Land holding, (xiii) Meteorology, (xiv) Irrigation etc. 

(b) Command based data processing and management system and development of spatial and non-spatial information into tables, charts and thematic maps. 

(c) Information management for forecast planning on optimum land use management options for the target area, etc. 

The software thus developed is capable of land clustering, water resource estimation, economic planning, crop and livestock planning, planning for conservation and land development through appropriate management interventions/water harvesting and recharging structures and also identifying the dormant resources and many user-friendly options. The logic of the analysis based on the carrying capacity of land and soil environment has been established through this study and has been incorporated in the system dynamics model for the project planning. The said logic has been incorporated in the Computer Software, SFRECOLAND Version 1. It is expected this study and wider application of this model will generate an essential information network which can possibly throw more light to the existing knowledge base.
