Economic Evaluation of Investments in Micro Irrigation Structures in Kandi Area of Punjab

Three types of micro irrigation structures, namely small dams (SD), lift irrigation structures (LIS) and Makowal type structures (MTS) were constructed by the Department of Soil and Water Conservation, Govt. of Punjab, Hoshiarpur division in the Kandi area of Punjab depending upon the availability of water at site, during the period 1990-91 to 1996-97. The impact evaluation has shown that the cultivated area has increased by 9.5 per cent, 3.2 per cent and 9.8 per cent and irrigated area by 600 per cent, 1038 per cent, and 253 per cent for SD (from 1991-92 to 2003-04), LIS (from 1993-94 to 2003-04) and MTS (from 1994-95 to 2003- 04), respectively in the selected villages of these structures. The income of irrigated hectare has been found higher at Rs 14478 than un-irrigated hectare. Discounted cash flow technique has revealed that the financial internal rate of returns are as high as 20.56 per cent, 38.54 per cent and 27.95 per cent for SD, LIS and MTS, respectively, which are highly satisfactory and encourage more public investments on such type of irrigation structures to enhance the income of Kandi farmers.Agricultural and Food Policy,

Technical Efficiency in Crop Production: A Region-wise Analysis

The technical efficiency in crop production has been reported in different regions as well as in the state of Punjab to show how different regions have adopted the latest technology. Technical efficiency of individual farms has been estimated through stochastic frontier production function analysis. The production function estimates have pointed towards the presence of disguised unemployment in the sub-mountainous region of the Punjab state. The technical efficiency has shown a wide variation across regions. The average technical efficiency has been found maximum in the central region (90 per cent), followed by south-western and sub-mountainous regions. The main drivers of inefficiency have been identified as experience in agriculture and age of a farmer. The policy intervention to improve technical efficiency being not the same for all the regions, the study has observed that the state would benefit more if policy interventions are developed at the local level.Agricultural and Food Policy,

Technical Efficiency of Wheat Production in Punjab: A Regional Analysis

The study has analysed the technical efficiency in wheat production across different regions of the Punjab state. It is based on the cross sectional data collected from a random sample of 564 farm households comprising 58, 318, and 188 households from semi-hilly, central and south-western regions for the year 2005-06. The mean technical efficiency of wheat production has been found as 87 per cent, 94 per cent, 86 per cent and 87 per cent in semi-hilly, central, south-western and Punjab state as a whole, respectively. The results signify that farmers of the central region do not have much scope to increase productivity of wheat through technical efficiency improvement under the existing conditions of input-use and technology. In the semi-hilly and south-western regions, the yield of wheat can be improved to the extent of 13 per cent and 15 per cent, respectively through adoption of better practices of technology. Across different regions, wheat area has contributed positively and significantly, the coefficient being highest and only significant variable for the central region. The coefficient of expenditure on insecticides and pesticides has been found significant for the semi-hilly region, demanding boost in the expenditure on insecticides and pesticides to increase wheat production in this region. The coefficient of fertilizer nutrients has been observed positive and significant for the semi-hilly and south-western regions, indicating that there is scope for increasing production of wheat by enhancing the use of fertilizers in these regions. Further, the technical efficiencies are positively and significantly related to age, education and experience of a farmer and percentage area under the crop.Agricultural and Food Policy,

The aerobraking space transfer vehicle

With the advent of the Space Station and the proposed Geosynchronous Operation Support Center (GeoShack) in the early 21st century, the need for a cost effective, reusable orbital transport vehicle has arisen. This transport vehicle will be used in conjunction with the Space Shuttle, the Space Station, and GeoShack. The vehicle will transfer mission crew and payloads between low earth and geosynchronous orbits with minimal cost. Recent technological advances in thermal protection systems such as those employed in the Space Shuttle have made it possible to incorporate and aerobrake on the transfer vehicle to further reduce transport costs. The research and final design configuration of the aerospace senior design team from VPISU, working in conjunction with NASA, are presented. The topic of aerobraking and focuses on the evolution of an Aerobraking Space Transfer Vehicle (ASTV), is addressed

Pre and Post Water Level Behaviour in Punjab: Impact Analysis with DiD Approach

Punjab Agriculture is trapped in the complex nexus of groundwater depletion and food insecurity. The policymakers are concerned about reducing groundwater extraction at any cost for irrigation without jeopardizing food security. In this regard, the Government of Punjab introduced the “Punjab Preservation of Subsoil Water Act, 2009”. The present paper examines the impact of the “Preservation of Sub Soil Water Act, 2009” on pre- and post-water levels in Punjab using the difference-in-difference (DiD) approach. The state has witnessed a severe fall of 0.50 m per year and 0.43 m per year for the post-monsoon and pre-monsoon season, respectively. Only 2.62 per cent of wells were in the range of 20–40 m depth in the state in 1996, which increased to 42 per cent and 67 per cent in 2018 for the pre-monsoon period, and post monsoon period respectively, depicting an increase of 25 times. The groundwater depth in high rice-growing(treated) districts declined by 1.53 and 1.39 m than the low rice-growing (control) districts in the pre-monsoon and post-monsoon periods respectively post the enactment of PPSW Act, 2009. A groundwater governance framework is urgently needed to manage the existing and future challenges connected with the groundwater resource
