Proceedings of Special Session on Drainage

Considering the significant contribution of irrigated agriculture to global food security and the need for provision of some form of drainage to sustain its productivity, a Special Session on Drainage was organized during the 60th IEC Meeting and 5th Asian Regional Conference on 8 December 2009. The objective of the session was to highlight the key developments in the area of drainage for semi- arid and humid regions including socio- economic and environmental issues, drainage materials and advanced diagnostic and prognostic tools.

Dr. Gurbachan Singh, Director and Dr. S.K. Kamra, Head, Division of Irrigation and Drainage Engineering, CSSRI, respectively were the coordinator and co- coordinator for the session. The Session was chaired by Dr. W.F. Vlotman. The following is the gist of the presentations made during the session:

Emerging contaminants in surface and drainage waters (Speaker: Dr. Shiv O. Prasher, McGill University, Canada)

Dr. Prasher elaborated upon the emerging and challenging problem of surface and groundwater pollution through non- point organic toxicants like pharmaceuticals. Pharmaceuticals used for human and intensive veterinary medicines for cattle are entering into the food chain through soil, surface and ground water, river and drinking water systems. The treatment plants are not equipped to deal with these contaminants, which have serious implications on aquatic, animal and human life and soil organisms. The concern of pollution by pharmaceuticals is growing in developed as well as developing countries, in particular after confirmation of their presence and ability to pseudo-persist in the environment. There is an urgent need to understand different dimensions of the problem and to find preventive and remedial measures. Dr. Prasher also presented encouraging results on the use of constructed wetlands as effective biogeochemical filters to remove various organic and inorganic pollutants from waste waters in Canada.

An overview of subsurface drainage research in India (Dr. Dr. S.K. Kamra, Head, Irrigation and Drainage Engineering Division, CSSRI, Karnal, India)

Dr. Kamra presented an overview of the systematic research conducted in India since 1980s on subsurface drainage for amelioration of waterlogged saline soils. Besides briefly covering the drainage works undertaken by other agencies, he provided detailed results on soil, hydro- geo- chemical characteristics and features of subsurface drainage systems and materials, introduced and evaluated by CSSRI, alone or in association with state universities and departments in Haryana, Rajasthan, Gujarat, Andhra Pradesh, Karnataka and Maharashtra. Till today, subsurface drainage projects of 800- 1200 ha pilot area each have been implemented in 7500 ha area in farmers’ fields in Haryana and about 40,000 ha throughout India. Dr. Kamra also covered the socio- economic issues on acceptance and operation of large scale subsurface drainage projects and options for disposal and management of saline drainage effluent. He emphasized three researchable issues of controlled drainage, application of field and regional models in association with remote sensing, GIS and geophysical (resistivity, electro- magnetic) techniques for characterizing, planning and management of regional salinity and drainage projects.  

Installation of large scale subsurface drainage system- A case study of Chambal command area, Rajasthan (Speaker: Mr. C.M. Tejawat, Command Area Development, Kota, Rajasthan, India)  

Mr. Tejawat presented historical development of measures undertaken to control waterlogging and soil salinity in Chambal command of Rajasthan during 1990s. These measures included starting from on-farm development (OFD) works during 1970s to subsurface drainage under Rajasthan Agricultural Drainage (RAJAD). He provided details on investigations, design, monitoring and evaluation of subsurface drainage installed on farmers’ fields in about 15000 ha area including socio- economic issues like cost effectiveness and compensation provided to farmers for crop loss during installation. He also provided details of complete station system and computer aided design and drafting software used extensively for regional survey and design activities in RAJAD. It was concluded that subsurface drainage is a successful technology for control of water table and soil salinity and to improve crop yields and was working satisfactorily with least maintenance. A recommendation that envelope is not needed in soils having more than 40% clay and SAR < 15 has implication for other drainage projects. 

Waterlogging control by subsurface and bio-drainage (Speaker: Dr. H.S. Chauhan, Retired Dean, PG Studies, GB Pant University of Agriculture and Technology, Pantnagar, India)

Dr. H.S. Chauhan presented an overview of historical backdrop, strengths and limitations of different drainage approaches such as surface drainage, ditch drainage, vertical drainage, subsurface drainage and bio-drainage in India. He emphasized the need to integrate different options and derive suitable mechanisms to control waterlogging and soil salinity for sustainability of agriculture and environment. There was in-depth discussion on the adoption of highly transpiring Eucalyptus and other trees (bio- drainage) for control of waterlogging, particularly as a preventive seepage control measure in the vicinity of canals and as well as in appropriate agro- forestry models.

Sustainable agricultural drainage, drivers, benchmarking and KPIs as part of IWRM (Speaker: Dr. W.F. Vlotman., ICID Theme Leader Systems and Chair, Working Group on Drainage, Australia)

Dr. Vlotman defined new drivers for subsurface drainage projects besides social, economic and conventional environmental indicators. New drivers of drainage and irrigated water resources management deal with environment, modernization and climate change issues to ensure basin – level sustainability based on uniform water laws. The features and scope of recent management tools and models such as DRAINFRAME, MASSCOTE and Global Reporting Initiatives, being used in Australia, were discussed in the context of benchmarking of drainage schemes with key performance indicators to evaluate the success of any project or organization in achieving the targeted objectives and vision. The importance of improvement in real time monitoring and evaluation infrastructure of drainage and water resource projects in South Asian countries was also emphasized.
