IBA faculty co-authors a paper analyzing the effects of climate change on production of rice
Dr. Heman Das Lohano, Professor, Department of Economics, School of Economics and Social Sciences (SESS), co-authored a paper titled, 'A district-level analysis for measuring the effects of climate change on production of rice: evidence from Southern India', published in the journal of Theoretical and Applied Climatology.
Climate change may cause adverse impact on agricultural production that could jeopardize food availability and security. In this paper, we investigate how changes in mean values and variability of weather variables may affect rice yield using panel data for 30 districts of Tamil Nadu State from 1971 to 2018. We estimate a fixed-effects regression model with panel-corrected standard errors. Results show that rainfall and temperature have a statistically significant impact on rice yield. Furthermore, weather variability, measured as standard deviations of temperature and rainfall, has a negative effect on rice yields. We use the Coupled Model Inter-comparison Project-5 outputs and dynamically downscaled the weather outputs using the regional climate model. The results of the climate model showed that the rise in temperature and disruptions in rainfall patterns including both excessive and deficient rainfall events in Tamil Nadu will continue in the future under different climate scenarios. Projected changes in the weather variables are likely to decrease rice yield in Tamil Nadu from 0.7 to 6.3% under the low emission scenario and 4.1 to 20.1% in the high emission scenario during 2022–2050 (relative to 1971–2018). These projections have implications for the planning and targeting of climate adaptation technologies such as drought-tolerant and flood-tolerant varieties to lessen the adverse impact of weather variability due to climate change in the future.

IBA faculty co-authors findings concerning use of energy-efficient cookstoves in Pakistan
Dr. Heman Das Lohano, Department of Economics, Institute of Business Administration (IBA), Karachi, and Inayatullah Jan, Institute of Development Studies (IDS), The University of Agriculture Peshawar, co-authored a paper that provides evidence of the fact that using biomass for cooking and heating is mainly responsible for global forest depletion and burden of diseases. The paper further elaborates that large-scale initiatives were globally taken for the dissemination of energy efficient stoves.
The paper was published in 'Renewable and Sustainable Energy Reviews'.
This study attempts to identify the enablers that play an important role in the uptake of energy efficient cookstoves (EECs) in Chitral, Pakistan. For this purpose, primary data were collected from 390 households distributed across 20 villages. The ordered logit model is used to analyze the factors affecting the uptake of EECs in the study area. The findings show that the education level of the household head, landholding by the household, presence of organizations working to promote EECs, and media campaigns promoting EECs have a statistically significant influence on the uptake of EECs. Of these factors, the presence of NGO promoting EECs has the largest influence on EEC adoption as it increases the probability of switching from traditional cookstoves to EECs by 20.5% points. Media campaigns for promoting EECs increase the probability of switching to EECs by 14% points. The study concludes that socio-cultural and economic variables as well as efficient dissemination of information and promotion of EECs have a statistically significant relationship with the uptake of improved and clean cooking technology. Based on the findings, the study recommends that, to ensure successful dissemination, local needs and preferences of users of the area be taken into account when designing an EEC program.
