“…Examples of such random shocks include weather (poor rainfall), floods, bushfires and diseases. These values are in the ranges of the findings of many of the research works reviewed (Hasan and Islam 2010, Teshome, 2005, Khairo and Battese, 2004, Oji et al, 2007. One major random shock which was found to influence the production of Maize during the study period in our study area was the inadequate rain fall which stopped before expected time and required amount.…”

Article InformationThe objective of this study was to examine the level of technical efficiency of smallholder maize producers and identify its determinants in Horo Guduru Wollega zone of Oromia Regional State, Ethiopia. A Cobb-Douglass stochastic production function model was used for the analysis. To specify technical inefficiency effects of socioeconomic variables, Maximum Likelihood Estimation (MLE) technique using data collected from 120 randomly selected sample farmers in 2011 was applied. The MLE results reveal that farm size under maize cultivation, chemical fertilizer (DAP) and maize seed are the major factors that are associated with changes in the maize output. The effect of land area on output is positive and the coefficient is found to be significant, implying the economies of scale. The test result indicates that there is inefficiency in the production of maize in the study area. The relative deviation from the frontier due to inefficiency is 85 percent. The average estimated technical efficiency for smallholder maize producers ranges from 0.06 to 0.92 with a mean technical efficiency of 0.66 (66%). The analysis also reveals that the educational level of the farmer, age of household head, land fragmentation, extension services, engagement in off-farm/non-farm activities, and total land holding of the farmer are the major socioeconomic factors influencing farmers' technical efficiency and maize output. The implication of the study is that technical efficiency in maize production in the study area could be increased by 34 percent through better use of available resources, given the current state of technology.

The present study aims at measuring the technical efficiency of wheat production under changing climate in drought prone areas of Bangladesh. The study employed farm level cross sectional data taken from 100 farmers using purposive random sampling technique from three upazilas of Thakurgoan district of Bangladesh. The study considered two successive years 2006 and 2007 as drought and normal year respectively on the basis of farmers' opinion and information collected from meteorological station. Semi-logarithmic regression model with dummy variable was used to estimate production variability of wheat due to drought. The findings showed that wheat production decreased by 17.4 percent on an average due to drought occurrence in the study areas. Cobb-Douglas stochastic frontier production function was used to determine the technical efficiency of the wheat growers and the factors which influence technical efficiency in wheat production. The empirical results of technical efficiency model showed that the effects of seed, pesticide, tillage, irrigation and fertilizer costs were significant in the production of wheat. Education, family size, farming experience, credit, extension-contact and farm size had negative effects on technical inefficiency of farmers which indicates that technical inefficiency decreases with the increase of these factors in both normal and drought years. The mean technical efficiencies were 67.00 and 86.40 percent in normal and drought years respectively. The results also indicate a good potential for increasing wheat production by 33 and 14 percent in normal and drought years respectively using the available resources and technology. Wheat farmers should give more attention to their farming practices and should take rationale decision for using farm resources efficiently.

“…Yield gap (Yg) is defined as the difference between Yp (irrigated systems) or Yw (rainfed systems) and actual farm yield (Ya) ( Van Ittersum and Rabbinge, 1997 , Van Ittersum et al, 2013 ). Although cereal yields in Bangladesh have increased substantially over time, previous studies have documented large Yg in farmers' fields ( Hasan and Islam, 2010 , Kashem et al, 2012 , Khan et al, 2013 , Mondal, 2011 , Schulthess et al, 2012 , Timsina et al, 2010 ), though these studies were limited to a few locations and did not look at the potential extra grain production in Bangladesh due to Yg closure.…”

Bangladesh faces huge challenges in achieving food security due to its high population, diet changes, and limited room for expanding cropland and cropping intensity. The objective of this study is to assess the degree to which Bangladesh can be self-sufficient in terms of domestic maize, rice and wheat production by the years 2030 and 2050 by closing the existing gap (Yg) between yield potential (Yp) and actual farm yield (Ya), accounting for possible changes in cropland area. Yield potential and yield gaps were calculated for the three crops using well-validated crop models and site-specific weather, management and soil data, and upscaled to the whole country. We assessed potential grain production in the years 2030 and 2050 for six land use change scenarios (general decrease in arable land; declining ground water tables in the north; cropping of fallow areas in the south; effect of sea level rise; increased cropping intensity; and larger share of cash crops) and three levels of Yg closure (1: no yield increase; 2: Yg closure at a level equivalent to 50% (50% Yg closure); 3: Yg closure to a level of 85% of Yp (irrigated crops) and 80% of water-limited yield potential or Yw (rainfed crops) (full Yg closure)). In addition, changes in demand with low and high population growth rates, and substitution of rice by maize in future diets were also examined. Total aggregated demand of the three cereals (in milled rice equivalents) in 2030 and 2050, based on the UN median population variant, is projected to be 21 and 24% higher than in 2010. Current Yg represent 50% (irrigated rice), 48–63% (rainfed rice), 49% (irrigated wheat), 40% (rainfed wheat), 46% (irrigated maize), and 44% (rainfed maize) of their Yp or Yw. With 50% Yg closure and for various land use changes, self-sufficiency ratio will be > 1 for rice in 2030 and about one in 2050 but well below one for maize and wheat in both 2030 and 2050. With full Yg closure, self-sufficiency ratios will be well above one for rice and all three cereals jointly but below one for maize and wheat for all scenarios, except for the scenario with drastic decrease in boro rice area to allow for area expansion for cash crops. Full Yg closure of all cereals is needed to compensate for area decreases and demand increases, and then even some maize and large amounts of wheat imports will be required to satisfy demand in future. The results of this analysis have important implications for Bangladesh and other countries with high population growth rate, shrinking arable land due to rapid urbanization, and highly vulnerable to climate change.
