The subject agribusiness has drawn an enormous attention by organized sector in national and multinational level with the recent move of the Government of India to allow Foreign Direct Investment (FDI) in the retailing sector. Technology driven efforts are very much important in this changed scenario to increase market efficiency reducing inventories, waste, and costs. Earth Observation Satellite (EOS) imagery driven Remote Sensing (RS) and Geographical Information System (GIS) technology can be utilized as a high-end Spatial Decision Support System (SDSS) to extract the different aspects of agriculture like land-use land-cover (LULC) condition, soil properties like moisture estimation, moisture conservation, crop identification, identification of suitable farming site for suitable crop, acreage estimation, crop monitoring, damage monitoring, and complete supply chain monitoring includes crop vehicle tracking integrating Global Positioning System (GPS). Increased availability of narrow band hyperspectral imagery from Hyperion sensor has prompted to explore hyeprspectral imagery to estimate the vegetation biophysical parameters and leaf biochemical used to detect nutritional and water stress condition. This paper summarizes the use of hyperspectral remote sensing for vegetation monitoring through biochemical and biophysical parameter estimation, discussing the potential for detecting water stress. Central to this objective is our primary research question: Can remote sensing play a key role to monitor agri-crop health to enhance the agribusiness efficiency?.Keywords

This paper attempts to explore structural changes of the Indian economy over the decade of the 1980s through 2006-7, using the Conventional and Modified Input-Output frameworks. Key sectors are identified using weighted backward and forward linkage measures and coefficients of variation. Results based on the Conventional model reveal structural change towards more or less modern production structure of the Indian economy, while that based on the Modified model reflects a mix of traditional and modern industry-oriented production structure. Results based on the Conventional method suggest policies that would focus more on the industrial sector, while those of the modified framework suggest that importance should be given to the traditional as well as modern industrial sectors. Thus, choice of the method of structural analysis for an economy is an important research agenda in the literature on the subject.- Economy-Wide Production Requirements for India’s Food Security Programme

The performance of food grain sector in an economy is crucially dependent on other sectors of the economy. Therefore, the task of meeting the target for food grain production in the Twelfth Five Year Plan should be addressed by considering an economy-wide consistent production framework which includes both agricultural and non-agricultural production. A Mixed Input-Output Model is used to identify the Vital, Essential and Desirable sectors for increasing food grain production in the economy. Results indicate that the feasibility of the Food Security Programme depends on the availability of capacity augmenting resources including foreign exchange to increase food production.- The Structure of the Sri Lankan Economy

Sri Lanka is a small island economy without much of natural resources. In spite of a troubled domestic environment in recent times, the country has recorded an impressive peiformance in the areas of Average Life Expectancy, Adult Literacy rates, Infant Mortality Rates and similar indices of develapment. However, economic growth, sustained employment generation, reasonable price stability, balance in the external sector, and reduction in income inequality have not been adequate though to proper economy into the league of Developed Nations.
The objective of this paper is to study the inter-sectoral linkages of this economy using Multiplier Analysis to understand his structure by measuring the degree of interconnectedness of its different sectors, since the effectiveness of policy measures is expected to depend on the degree of interconnectedness of an economy. For this purpose, the Extended Input-Output Methodology combining the Leontief (1941) and Ghosh (1958) Models has been used.
The results show that the various sectors of the economy are weakly integrated, which is perhaps the reason why the effects of growth and development oriented policies have not percolated down throughout the economy. The development of strong inter-sectoral linkages is therefore a necessary prerequisite for the country's overall economic development.

Objectives: To understand the modus operandi of the street hawkers and analysing the impact of these operations on the revenue of the Government due to non-payment of taxes.
Methods/Statistical analysis: The study is prepared using primary data. The methodology followed is by conducting survey of 200 street hawkers from 8 prominent street hawker markets of Kolkata by way of predefined questionnaires which included quantitative questions. The statistical tool used to analyse the data are pie charts, histograms and arithmetic mean. The primary assumption taken is that the data is uniformly distributed thus arithmetic mean could be applied appropriately.
Findings: The study addresses the issue of government revenue loss due to the power conferred by the Income Tax Act to the persons earning income from Business and Profession. The street hawkers are perceived to have very low income but to the contrary of popular believe a significant section of the street hawkers earn more than basic exemption limit of Income Tax. However these street hawkers never pay taxes or file return thus these incomes are never reported consequently leading to huge revenue losses to the government. The revenue loss of the government is on account of 3 heads: Income Tax, Indirect Taxes and Licensing fees, this revenue is distributed among the state and the central government. The other issue resolves around the rampant corruption associated with the street hawkers operations, as per the findings of the survey it was found that around 1-2% of the total revenue of the street hawkers is paid to police or government officials and political leaders to be allowed to operate on the streets.
Application/Improvements: To minimise the revenue loss the Government can implement the Presumptive Taxation Scheme for Income Tax and Composition Scheme for Indirect Taxes for the street hawkers on turnover.
