Performance of rain-fed Aman rice yield in Bangladesh in the presence of climate change

Abstract

This paper uses the framework of the Just–Pope production function to evaluate the impacts of climate change on yields of the rainfed Aman rice crop in Bangladesh. It analyses disaggregated district-level data on climate variables and Aman rice yield over a 48 year time horizon. The results reveal that changes in maximum temperatures have had positive and negative effects on yield in the linear and quadratic functional forms, respectively. However, the elasticity values in the variance function confirm that maximum temperature is risk-increasing for Aman rice while minimum temperature is likely to decrease yield variability. Rainfall has become risk-increasing for Aman rice. Based on three climate change scenarios, this paper also reveals that future climate change is expected to increase the variability of Aman rice yields. Finally, statistically significant dummies for different in-country climate zones require zone-specific adaptation policies to reduce the adverse impacts of climate change.

The impact of climate change on maize yields and its variability in Telangana, India: A panel approach study

“…This infers that all the study variables are stationary. The results of the unit root test are consistent with Kim and Pang () and Sarker et al (). Hence, we apply the three‐stage FGLS estimation approach to investigate the influence of climate change on maize yields.…”

“…A Hausman specification test was employed to decide which method should be used. Hence, this study selected a fixed effects model based on the Hausman test result, and this preference of fixed effects model is consistent with former studies (Cabas, Weersink, & Olale, ; Kim & Pang, ; Sarker, Alam, & Gow, ).…”

Drought, Climate Change, and Dryland Wheat Yield Response: An Econometric Approach

“…Previous empirical studies of production have applied either a linear functional form of the independent variables (e.g. Chen, McCarl and Schimmelpfennig [ 50 ], Arshad, et al [ 55 ], Mahmood, et al [ 56 ]) or a non-linear form (e.g., Horowitz [ 57 ], Sarker, Alam and Gow [ 54 ], Sarker, Alam and Gow [ 11 ], Isik and Devadoss [ 58 ]). Hence, in this study, the Just-Pope approaches with both linear and nonlinear (i.e.…”

“…Extensive studies have investigated the impacts of climate change on crop yields in different parts of the world [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. For example, Gupta and Mishra [ 15 ] investigated the impact of climate change on rice production in India using a crop simulation model and Global Climate Model (GCMs) outputs.…”

Hydrological impacts of climate change on rice cultivated riparian wetlands in the Upper Meghna River Basin (Bangladesh and India)

“…At this time, the shallow haor wetlands turn into extensive arable land for Boro rice cultivation. Although dry-season Boro rice is the main crop, Aman rice, another local rice variety, is cultivated on comparatively higher-elevation land that is less prone to inundation during the period August-December (Sarker et al 2017).…”
