Abstract/ Executive Summary:

The unavailability of suitable technologies including stress-tolerant cultivars, management options, irrigation facilities as well as extension supports is the key challenge for the intensification of cropping through horizontal and vertical extension approaches. This study assesses the potential for increasing rice production through a horizontal extension approach. The historical and projected trend of area and production of rice, major cropping patterns, and cropping intensity, as well as expert opinion, was the basis for the extrapolation of the intensity of cropping by 2030. The analysis shows that about 1.52 M ha area with a fallow period of the existing major cropping patterns and 0.65 M ha fallow land is potential for additional rice cropping. Resulting from that about 5.8 million tons of additional rice can be added to total rice production in the country. Inclusion of a rice crop in a certain percentage of the existing major cropping patterns, such as Boro-Fallow-T. Aman (25%), Boro-Fallow-Fallow (50%), and Fallow-Fallow-T. Aman (40%) may contribute, respectively 1.38 million tons, 1.57million tons, and 0.80 million tons of rice in the total rice production. Besides, the addition of a certain percentage of cultural waste (50%), marshy land (25%), newly developed char land (50%), and Jhum (60%), and other extrapolation areas of Chittagong Hill Tract, respectively may contribute 0.4 million tons, 0.25 million tons, 0.34 million tons and 0.06 million tons rice in the total rice production. Strategic policy supports are required for implementing appropriate action plans to achieve the goals.

Objectives:

To rice production, extrapolation of total rice production by 2030 and conclusions are outlined.

Methodology:

Secondary data were used for the study and mainly collected from different published sources including the Statistical Yearbook of Bangladesh (BBS, 2017a) and Year Book of Agriculture Statistics (BBS, 2017b). The future trend of various data until 2030 was projected based on historical data. Either 1969-70 or 1975-76 was considered as a baseline for the projection of future trends of different indicators subject to availability. Most of the data showed linear change over time; therefore, the best fit linear regression model was used to predict the future trends of different indicators to identify the way of boosting up rice production. The historical and projected trend of area, production of rice, and cropping intensity, as well as expert opinion, were considered as a basis for extrapolating the percentage of area is potential for inclusion a rice crop in the fallow period of the major cropping pattern and percentage of fallow land could be under rice cultivation in 2030.

Achievement/Findings:

Sustainable intensification of rice cropping might be possible for meeting up food security challenges for the growing population in 2030 through the introduction of a rice crop in 2.211 M ha in the fallow period in the existing major cropping patterns and utilizing fallow land for rice cropping. About six million tons of additional rice can be added to total rice production through strengthening policy supports for implementing appropriate action plans to achieve the goals.
