Participatory Resource Mapping (PRM)

Year: 1992

Technical details: For a sustainable development planning in a micro level, database of various natural and man made resources of that geographic location is a must. A model for studying the physical and natural resources of a village was developed by KSSP during the 80’s. IRTC has modified, perfected and finalised this by providing the scientific inputs with the help of Centre for Earth Science Studies, Thiruvananthapuram, but retaining the participative aspect. The PRM methodology developed by IRTC involves preparation of a set of thematic maps showing land use, water availability, land form, surface material, infrastructure and environmental appraisal and a socio-economic survey. This will help to prepare comprehensive long term local area plans for sustainable development with active participation of the local people. 

Needs addressed: To provide a database of various resources in the form of a map for preparing developmental plans at local level.

Field trial results: The methodology for preparation of resource maps with people’s participation was developed and optimised and finalized through a number field trials at Panchayath level. The methodology was perfected with the help/input from experts.

Experts and Institutions involved or associated: Dr. Thomas Isaac, Dr. M.P. Parameswaran, Experts from Centre for Earth Science Studies, Govt of Kerala and KSSP/IRTC activists.

Propagation efforts: This methodology was very well accepted by both local bodies, Govt. department and S&T institutions. Based on this model, Resource Maps of more than four hundred Panchayaths have been prepared as a supporting database for developmental plans. Many scientific institutes like the Land Use Board, Information Kerala Mission, The COSTFORD, etc. have used this model with minor modifications.

 

Group Approach to Locally Adaptable and Sustainable Agriculture (GALASA)

Year: 1991

Technical details: This is a ‘scientific agriculture’ package for increasing the production of paddy in each ‘Padasekharam’ through developing and utilizing the available resources of land, water; manpower and other components of production as group activity.

Technical details: IRTC have adapted the concept of low cost construction and with use of cost effective methods in building construction like Ferro cement slabs, Rat-trap bonding, Filler slab roofing, Arches, Brick jally, Corbelling, Pre-casting of Hand rails, etc. Using these techniques one can save about 30-50% in the housing construction, retaining the aesthetics or with better aesthetics. The focus was in reducing the unnecessary expenditure for getting ‘more strength’ through optimum use of materials and also to change some of the ‘concepts’ of housing among the people.

Needs addressed: Housing needs of rural poor, alternate environmentally better housing 

Field trial results: The field trials gave good results in terms of thermal comfort, durability, attractiveness, low cost and optimum usage of locally available materials. 

Experts and Institutions involved or associated: Dr. Lary Baker, Mr. Benny Kuriakose, Prof. K. Viswanathan and other KSSP/IRTC activists

Propagation efforts: The idea was mainly popularised through the KSSP. IRTC have conducted a number of training camps, workshops, etc. for the masons and other skilled labourers in low cost construction techniques. A separate wing of IRTC called ‘Mithavyaya’ was formed for the popularisation of these techniques. Later as the concept became popular other voluntary organisations like COSTFORD and Nirmithi Kendra have also started training the masons. The concept was very well received and thousands of houses constructed on these principles can be seen throughout the state.

 

Parishad Chulha –A Fuel efficient wood burning Chulha

Year: 1987

Technical details: IRTC has developed a fuel efficient wood burning Chulha for use in kitchens. Apart from the brick and mortar/mud, the improved Chulha consists of pottery moulds, which were specially designed for this, asbestos pipes and iron gratings. The cost of one Chulha will be about Rs. 800/- including material and fitting charges. The fitting or construction of the Chulha needs special training. IRTC has also developed a community Chulha for cooking in large quantity in schools, hotels and hostels.

Needs addressed: Fire wood shortage, Environmental safety, Health hazard and more employment opportunity for potters and fitters. 

Field trial results: It has a fuel efficiency of 28% as certified by CPRI, Bangalore in comparison with 9% for conventional Chulha. This has reduced the firewood expenditure to 1/3 of the normal. The new model has the additional advantage that it is “smokeless” and therefore hazard free.

Experts and Institutions involved or associated: Apart from the activists of KSSP and IRTC, institutions like CPRI, Bangalore and Govt. Engg. College Trivandrum were involved. 

Propagation efforts: In the initial stages this was propagated through the parent organization KSSP. Later this model was approved by MNES and now it is being propagated by the Governmental agency ANERT throughout the state. Also KSSP and other VOs are propagating this. More than five lakh units were installed so far.
