Sugarcane (Saccharum L.), takes almost a year to grow [5]. variation observed value 0.11. The major cropping systems viz. rice-wheat, maize-wheat, In ERDAS IMAGINE, create a pseudo colour table to set the sugarcane/ratoon-wheat, maize-mustard and Pearlmillet – value 0 is red/orange color, green/yellow ranges are between are groundnut are grown in Western U.P. The cropping systems are 255. The time series remote sensing SPOT VGT data is useful to changing due to changing of climatic pattern. In terms, understand changing of major cropping systems. The major traditional crop grown areas changing other crop grown areas climatic parameters viz., minimum/maximum temperature and due to rising temperature, heavy rain, drought or pest impact. It average /normal rainfall are important for crops and cropping may be other factors viz. cash crop gives more profit than systems. The changing of climatic parameters is adverse affected traditional crop like herbal crop (medicinal plants) and on the grown areas. horticultural crops (seasonal flower). Cropping system level study is not only useful to understand the overall sustainability of Introduction agricultural system, but also it helps in generating many important parameters which are useful in climate change impact Agriculture and associated industries are the primary source of assessment [6]. Climate change will increase both abiotic food and the major employment sector. The agriculture sector stresses, such as drought, and biotic stresses, such as pest and contributed 17.2 per cent; industry contributed 18.5 per cent crop disease pressures, on agricultural systems Climate is one of while the service sector had a contribution of 64.5 per cent of the the most important input factors in the agriculture productivity in GDP according to 2008-09 estimates [1]. Uttar Pradesh, has all over the world. Pattern of temperature and precipitation are geographical area of 2,40,928 Km2 which constitutes 7.3% of the changing due to global warming, resulting in having impact on total area of country [2]. Western UP is one of the prosperous crop productivity [7]. The climate is the overall pattern of the agricultural tracts of the country [3] In Uttar Pradesh (plains) weather in a region over a long period of time. Climate change is roughly 18% of gross agricultural output is sugarcane while its one of the most important global environmental challenges of the share in area cultivated is only around 6 percent. Western U.P. present century. The most visible impacts of climate change are crop calendar has three cropping seasons- rabi, kharif and zaid. the increased global mean surface temperature; increased The kharif cropping season is from July to October during the frequency and severity of drought, variations in precipitation, and south-west monsoon and the rabi cropping season is from increased heavy precipitation events. All these manifestations October to March (winter). In between the rabi and the kharif have a significant impact on world agriculture. As per the findings of the study conducted by the Indian Agricultural Research Institute (IARI) New Delhi, with every 1ºC. increase in ISSN No: 2319-3484 Volume 2, Issue 3, May 2013 36 International Journal of Remote Sensing & Geoscience (IJRSG) www.ijrsg.com temperature throughout the growing period of the crop, the total geographical areas of UP 240,928sqkm and western UP has overall wheat production may be lost by 4 to 5 million tones [8]. 72,018 sq.km percentage of total area is 29.6 % rest area 70.4% According to new reports by the Consultative Group on UP. Coordinates of Western Uttar Pradesh are as following: International Agriculture Research. Important crops like maize Latitudinal extent - 29° 58′ 12″ N to 26° 28′ 12″ N Longitudinal and wheat produce less grain at temperatures above 30 degree extent - 77° 35′ 0″ E to 80° 6′ 0″ E. It lies between the two Celsius [9]. important streams – the Ganga and the Yamuna. Western Uttar The statistical information on crop area, production and Pradesh shares borders with the states of Uttarakhand, Haryana, productivity form the backbone of agricultural statistical system.
