Chhattisgarh, India Environmental characterization for sustainable crop production in Chhattisgarh Agroclimatic zones: A review Hemant Kumar Bhuarya and R Singh Abstract A method for assessing and implementing sustainable crop production is needed to give practical relevance to the frequently used term "sustainable agriculture” Agro-climatic zones can be defined as a land unit having a greater degree of commonality or homogeneity with respect to various conditions and resources such as climatic parameters important for agriculture and cropping pattern etc. Food and agriculture Organization (FAO) of United Nations and International Institute of Applied System Analysis (IIASA) have developed a methodology for characterization of Agroclimati condition Agro-ecological zones. This method provides a wide range of different activities. Which are often related yet quite different in scope and objectives like characterization relevant to agriculture production. identifying crop specific limitations. Quantification of land productivity and population supporting capacity of land and multi criteria optimization. Agro-ecological zoning is one of the most important bases for agricultural developmental planning because the survival and failure of particular land use of farming system in a given region heavily realizes on careful assessment of agro-climatic resources. Keywords: environmental, agro-climatic zones, FAO and sustainable Introduction The Chhattisgarh came into existence on 1 st November 2000 as a result of bifurcation of Madhya Pradesh state. Chhattisgarh is located in the central part of India between the latitudes of 17° 46’N - 24° 5’ N and the longitudes of 80° 15’ E - 84° 20’ E. Its proximate position with the Tropic of Cancer has a major influence on its climate. It is landlocked by the states of Maharashtra and Madhya Pradesh on the west. Uttar Pradesh on the north. Jharkhand on the north-east. Orissa on the east. and Andhra Pradesh on the south Sprawled in an area of 135. 194 sq km. The climate of the state is dry sub humid type. The average rainfall of the state is around 1400 mm of which more than 90% is received during the south west monsoon (June-September). The onset of monsoon is around 10 June in southernmost tip of Bastar district and extends over the entire area by 25 June. The monsoon starts withdrawing from mid September and by 25 th September it withdraws from the entire state. Chhattisgarh is divided into three distinct Agro – climatic zones viz. Chhattisgarh plains. Bastar plateau and Northern hills and it covers 50.52%. 28.62% and 20.86% geographic area. respectively. Similarly. topographically also the state varies a lot from high elevated areas of the state makes it to differ in their climatic elements also. There is a wide variability in climatic factors also on an average a total of 1200 – 1600 mm. annual rainfall is recorded in different parts of Chhattisgarh in about 64-91 rainy days. (About 90% of rainfall in C.G. concentrated to four monsoon months i.e. June – September.) It has been recorded that 1000-1200mm. 1200-1400mm and 1400-1600mm. annual rainfall are received in Chhattisgarh plains. Bastar plateau and northern hills respectively. Similarly variations can be seen in temperature and humidity. In view of these studies on environmental characterization for sustainable crop production in Chhattisgarh is carried out mainly to capture the important agricultural features of the districts and to analyze the long term rainfall records in order to understand the pattern of rainfall and its spatial and temporal variability. In this study. Attempts are also made to examine the climate fluctuations and shifts in different districts to understand the pattern on climate variability that May influence the existing cropping pattern in the districts. Based on the historical data of crop productivity of major important crops like Rice. Wheat and Maize.
