Watershed programmes in India are contributing to water resources development, agricultural production and ecological balance. Conventional methods to value them using financial measures attempt to quantify the impacts of watershed development in an isolated manner. In order to evaluate the impacts of watershed programmes in a holistic manner, the Economic Surplus (ES) approach has been applied using the data from a cluster of 10 watersheds in the Coimbatore district of Tamil Nadu.The distributional effects of watershed programmes are also captured through the ES method. Hence, possibilities of using this methodology in the future watershed evaluation programmes could be examined. The study has suggested that people’s participation, involvement of Panchayati Raj Institutions, local user groups and NGOs alongside institutional support from different levels, viz. the central and state government, district and block levels should be ensured to make the programme more participatory, interactive and cost effective.

Field experiments were conducted at Central Farm, Coimbatore to develop a technology package for aerobic rice cultivation from 2004 to 2007. Among 12 rice varieties evaluated, PMK 3 proved to be the best variety in terms of production. The study of plant population in aerobic rice revealed that 100 hills/m2 (20 x 5 cm) was comparable with 50 hills/m2 (20 x 10 cm) in terms of grain yield. Irrigation at IW/ CPE of 1.2 (with water requirement of 618 mm) registered a grain yield of 4.9 ton/ha and was comparable with the grain yield of 4.8 ton/ha in irrigation at IW/CPE of 1.0 (with water requirement of 556mm). Among the N levels, N at 175 kg/ha produced the highest grain yield of 4183 kg/ha and it was comparable with N at 150 kg/ha (4030 kg/ha). To find out the suitability of aerobic rice in Cauvery delta region, a field experiment was initiated in PAJANCOA & RI, Karaikal to screen suitable rice varieties (ADT 36, ADT 43, ADT 48, PMK 3, MDU3 and ADS 18) for aerobic cultivation in comparison with other rice production systems. The grain yield of rice is higher in transplanting and wet seeding when compared to aerobic rice system. However, the most salient feature of this study is that about 92, 42 and 40.6% of water (including rainfall) was used for evapo-transpiration or consumptive purpose while remaining 8.0, 58.0 and 59.4% of water would have left the root zone as seepage and deep percolation, respectively.

As the short- and long-term impacts of climate change are becoming more visible at smaller regional scales, frequent occurrence (absence) of erratic precipitation as well as water scarcity issues can be identified as reliable indicators for predicting meteorological droughts. A supervised declaration of meteorological drought based on available precipitation data requires an understanding of reliability and consistency of drought indices for appropriate severity classification. An attempt has been made in this study to critically evaluate the performance of six popular drought indices namely, Standardized Precipitation Index (SPI), China Z Index (CZI), Modified China Z Index (MCZI), Deciles Index (DI), Rainfall Anomaly Index (RAI), and Z-Score Index (ZSI) for four districts in Tamil Nadu falling under arid (Karur), semi-arid (Cuddalore), dry sub-humid (Kanyakumari) and moist sub-humid (Coimbatore) conditions based on 120 years of precipitation records. Results showed that the SPI and CZI provided similar quantification of drought events (about 18% of the total months) irrespective of their climatic considerations while ZSI and RAI resulted in overestimation of drought severity (about 30–47%). Based on the classification strategy adopted for the selected indices, a framework for drought vulnerability assessment is proposed in conjunction with the estimated drought severity classifications.
