“…The positive impact of minimum temperature on cotton yield may be unable offset the adverse effect of maximum temperature as reflected in estimated results. Present results of minimum and maximum temperature in mean yield function of cotton are contrary to some studies such as Padakandla (2016) and Guntukula (2020). The empirical outcomes of climatic factors in mean yield function of cotton are similar with Kumar et al (2015).…”

“…Generally, the fixed effects (FE) and random effects (RE) models are designed to estimate the panel data model (Baltagi, 2005). This study selected fixed effects model based on Hausman test results and this preference of fixed effects model is consistent with few existing studies (Barnwal & Kotani, 2010;Cabas et al, 2010;Guntukula & Goyari, 2020;Kim & Pang, 2009;Sarker et al, 2014).…”

This study has examined the effects of climatic factors on mean yields and yield variability of four primary crops (rice, cotton, jowar and groundnut) in Telangana state by applying the Just and Pope production function over a period of 1956–2015. Using the three-stage feasible generalised least squares estimation procedure, we have estimated the production function of four crops. The empirical results have revealed that the effects of changes in climatic factors vary among crops under study. Maximum temperature has a significant adverse effect on rice, cotton and groundnut yields. Minimum temperature has a substantial positive effect on rice, cotton and groundnut. Further, rainfall is adversely related to cotton and groundnut yields. Maximum temperature has appeared as a risk-reducing factor for all study crops while minimum temperature as a risk-enhancing factor for rice, cotton and jowar. Lastly, rainfall has been found as a risk-enhancing factor for rice and groundnut whereas it is a risk-reducing factor for jowar and cotton. Results from the study have important implications on how Telangana’s farming sector will adapt to climate variability and change for sustainable agricultural development.

“…The present study will use both of these approaches to some extent and analyze the impacts of climate change on economic growth and its components, that is, agriculture, manufacturing and services. Guntukula and Goyari, (2020) incorporated climate change in the production function, and this model will be used as baseline in the present study because it provides theoretical basis for incorporating climate change into economic growth equations. Consider the production function.…”

This study has examined the potential impacts of climate change on Nigerian economic growth using a time series data (1980-2017). In doing so, an econometric model has been constructed based on theoretical and empirical literatures of the climate change economics, then it has employed a growth model adapted from the Solow growth model. The research work found that annual average rainfall has a significant effect on economic growth both short-run and long-run. Also, there is a high degree of positive and significant relationship between carbon emission, foreign direct investment, gross fixed capital formation and economic growth under investigation. The result also revealed that this relationship between climatic factors and economic growth is more noticeable in the long run. In addition, an inverse relationship was found between forest depletion, population growth and economic growth in the long run. Finally, there is unidirectional causality between annual average rainfall and economic growth in Nigeria. It is therefore recommended that the stakeholders and the general public should build green economy that enables sinking carbon and promotes carbon market in the long-run.

“…Along with the studies on physical impact of climate on crop yields (Lahari & Roy, 1985; Selvaraju (2003); Gurugnanam et al, 2010); there is a fair amount of literature on monetary impact of climate on yields (Fishman, 2012; Guiteras, 2009; Krishnamurthy, 2012; Kumar, 2009; Kumar & Parikh, 2001). Alternatively, studies have estimated the how climate change has impacted the land value or net revenues (Massetti & Mendelsohn, 2011; Mendelsohn, Nordhaus, & Shaw, 1994) Studies have also been undertaken to study the impact of climate on crop yields at the state level in India (Das et al, 2009; Guntukula & Goyari, 2020; Gurugnanam et al, 2010; Kandiannan, Thankamani, & Mathew, 2008; Kumar & Kaur, 2019; Padakandla, 2016; Saseendran, Singh, Rathore, Singh, & Sinha, 2000).…”

Observational data shows that there have been significant regional variations in climate change patterns across India. This study examines the effects of climate change on yields of rice across different climatic zones in the former state of Andhra Pradesh. The study uses district level panel data for 30 years (1981–2010) to analyze the influence of climatic variables like rainfall, maximum temperature and minimum temperature on rice yields at the agro‐climatic zone level. Analysis of data shows that the degree of impact of climate on yield of rice is varied across different climatic zones in the former state of Andhra Pradesh. Climatic zones which have traditionally higher temperature and lesser rainfall are more susceptible to variations in climate than others. Though the negative impact of temperature is similar among all the zones, there are observable spatial variations and differences in the degrees of impact The study also found that the impact of irrigation is significantly higher in traditionally drier zones than others. Given significant regional variations on climate change impact, policy makers, administrators and crop scientists have to design micro‐level mitigation and adaptation techniques.
