Abstract/ Executive Summary:

An experiment was carried out to reveal the precipitation pattern and to find out the interrelationship between precipitation and production of rice in Rangpur district. Rangpur division is more favorable for rice production. Monthly and yearly precipitation data (1983-2013) were collected from Bangladesh Meteorological department (BMD), Agargaon, Dhaka; Bangladesh Agricultural Research Council (BARC), Farmgate, Dhaka and rice production data were collected from Bangladesh Rice research Institute (BRRI); Department of Agricultural Extension (DAE), Rangpur, Bangladesh. From the analyzed precipitation data, it was clearly found that in 1984, 1985, 1987, 1999 and 2005, there were heavy precipitations and resulting flash flood. The average precipitation of Rangpur was higher (1344 mm) in 1987 than 1984, 1985, 1999 and 2005. In Rangpur district, rice production was the highest in the year of 1983, 1986, 1988, 1989, 1990, 1991, 1992, 1993, 1995, 1996, 1997, 1998, 2001, 2002, 2003, 2004, 2007, 2008, 2009, 2010, 2011, 2012 and 2013 and lower in the year of 1984, 1985, 1987, 1994, 1999, 2000, 2005, and 2006 on the basis of total annual precipitation. Rice production reduced main two reasons such as, heavy precipitation causes flash flood and lower precipitation causes drought stress condition. Both are threat-full for higher rice production. The results show that more precipitation in the years of lowest rice production period, heavy precipitation responsible for deduction of rice production area because of flooding and drought and also shows that normal/ minimum precipitation favorable for rice production at Rangpur district. From this study, it is concluded that the irregular precipitation of period (1984, 1985, 1987, 1994, 1999, 2000, 2005, and 2006) was not satisfactory for rice production due to heavy and/or excessive lower precipitation that resulting flood and/or in part of Rangpur district of Bangladesh. The analysis exposed that precipitation was one of the most important factors for higher amount of rice production in Rangpur district.

Objectives:

To find out the interrelationship between precipitation and rice production in Rangpur district.

Methodology:

Study area- On the basis of rice production and precipitation pattern, northern region of Bangladesh is advanced than the other areas. Among the northern region Rangpur district was selected as the study area, mainly considering the individual meteorological station. This district is bordered on the north by Nilphamari district, on the south by Gaibandha district, on the east by Kurigram, and on the west by Dinajpur district. In Rangpur district there have 2,641.84 km² of land. According to the census of 2014, total rice production area is 6, 81,405 acre (BBS, 2013). For, rice production needs a high amount of water which is highly dependent on rainfall and a certain temperature. The climate of Rangpur is humid subtropical with a predominantly hot and humid summer and a relatively cool winter. The city belongs to the monsoon climatic zone, with annual average highest temperatures of 23°C (Aug-Oct) and average lowest temperature of 7°C (Jan-Feb). Nearly 80% of the annual average precipitation of 3334 mm occurs between May and September (Islam and Uyeda, 2007). Data Sampling and Analyses- In this study monthly and yearly data of precipitation were collected from Bangladesh Meteorological Department (BMD), Agargaon, Dhaka. Some missing data of precipitation were also collected from Bangladesh Agricultural Research Institute (BARI), and Bangladesh Agricultural Development Council (BARC). All rice production data was collected from Bangladesh Rice Research Institute (BRRI) and Bangladesh Agricultural Research Institute (BARI), Rangpur, Bangladesh. All data were put into MS Excel spreadsheet for data analysis. For data analysis there were some calculations such as average, standard deviation etc. Average and standard deviation were calculated with the help of MS Excel spreadsheet.

Achievement/Findings:

In Bangladesh, different climate change induced events such as recurring floods riverbank erosion, drought in dry season have been augmenting vulnerability in this region and leaving impacts on the yields of crops. Contextual analysis suggests that unless urgent actions are taken, climate change will undermine efforts to ensure food security. From this study, there has been changing pattern of precipitation in 31 years (1983 2013) in Rangpur meteorological station surrounding the selected location and the changes of those climatic parameters are significant during this period. Food productivity will be particularly sensitive to climate change, because crop yields depend directly on climatic conditions (precipitation patterns). In tropical regions like Bangladesh (Rangpur), even small amounts of warming will lead to decline a large amount of crop (rice) production. In cold areas, crop harvests may increase first for moderate increase in temperature but then fall. Higher temperatures will lead to large decline in cereal (e.g. rice, wheat) production around the world. The research noticed that the changing pattern of precipitation for the selected regions are significantly higher compared to IPCC prediction over the world in last 100 years, which have considerable negative impacts on crop production like as rice production. In Rangpur district, different climate change induced events such as recurring floods and drought, have been augmenting vulnerability in many regions and leaving impacts on the rice production. Agriculture of Rangpur district is highly vulnerable to variation in weather patterns and is therefore extremely at risk from climate change, which will affect food security, particularly in the southern coastal and northern drought-prone areas of Bangladesh.
