crops. The data varies from field to field and even within the field if multiple crops
are being grown.
These data sets are very important for handling the irrigation schemes in real
time. The resilience of the particular type of intervention is measured by the
capacity of the scheme to handle the shortfalls with minimal impact on crop growth.
The data also determines one of the sides of the most important demand–supply
equation. However, the data is very difficult to come by in view of the competing
sectors and competing political and social entities demanding as large a share as
possible so as to ensure the security of their investments.
2.6 Urban and Industrial Water Management
Urban water management requires the data on the similar pattern as that of agriculture water management above but also needs to concern about its chemical and
biological composition. The quality assumes great importance. Unlike agricultural
water management, where the beneficiary area can be tailored as per the resource
availability, in case of urban water management, information about alternative or
augmenting sources of water is needed.
It has been observed that the urban land use planning has the tendency to vary
greatly and that impacts the consumptive demands by having greater population
densities compared with the earlier plans. The actual demand that may be
encountered keeping in view the trends in development on the ground is necessarily
required as input for any development and management exercise.
Another major impact of the urban water management issue is the effect on the
water quality through its effluents. It has been observed that about 80% of the
supplied water is returned as poor quality water needing extensive biological and
chemical treatment. The causes and impact is multi-dimensional and needs data
pertaining to water usage in various areas, catchment areas of the sewage treatment
plants, if any and also the type and nature of industries operating in the urban areas.
Many industries like thermal power generation, agro-processing industries
including paper and pulp, chemical, drugs and fertilizer industries, cement manufacturing, coal processing and steel industries generate considerable of effluents
which pose serious water quality hazards of the natural waters. Quality management
requires data on the treatment methodologies employed and real-time performance
of the same.
