Climate change and livestock production: the impacts are mutual
Cheng, M., B.A. McCarl, and C.J. Fei, "Climate Change and Livestock Production: A Review", Atmosphere, 13, 140.https://doi.org/10.3390/atmos13010140, 2022.
Abstract: Globally climate is changing, and this has implications for livestock. Climate affects livestock growth rates, milk and egg production, reproductive performance, morbidity, and mortality along with feed supply. Simultaneously, livestock is a climate change driver, generating 14.5 percent of total anthropogenic GHG emissions. Herein we review the literature addressing climate change and livestock, covering impacts, emissions, adaptation possibilities, and mitigation strategies. While the existing literature principally focuses on ruminants, we extended the scope to include non-ruminants. We found that livestock is affected by climate change and does enhance climate change through emissions but that there are adaptation and mitigation actions that can limit the effects of climate change. We also suggest some research directions and especially find the need for work in developing country settings.

Who drinks coffee and what are the influential factors of the demand?
Capps, O., Cheng, M., Kee, J. and Priestley, S.L., "A cross‐sectional analysis of the demand for coffee in the United States", Agribusiness, 2022. https://doi.org/10.1002/agr.21779
Abstract: The purposes of this study were to develop a profile of households who purchase coffee, to determine the socio-economic determinants of the demand for coffee by US households, and to update the own‐price, cross‐price, and income elasticities of demand for US households. The profile suggests targeting wealthier households, households without children living in the household, older households, white households, and households located in the Pacific region and in New England. The own‐price elasticity of −1.93 indicates that the demand for at‐home purchases of coffee is elastic. Tea is a substitute for coffee. Given the income elasticity of 0.20, changes in household income are not likely to have sizeable impacts on at‐home coffee consumption. Nevertheless, coffee is a necessity in economic parlance. The source of data for this analysis was the NielsenIQ pertaining to 61,380 households for the calendar year 2015. [EconLit Citations: D1, D9, D12].

How does long-term climate variability impact crop yield?
M. Wang, Y.K. Huang , M. Cheng, B. Sheng, B. McCarl, 2021. El Niño Southern Oscillation and Decadal Climate Variability Impacts on Crop Yields and Adaptation Value. CAB Reviews, 16(43), pp. 1-13.
Abstract: Ocean-atmospheric phenomena (OAP) have been found to be associated with regional climate variability and, in turn, agricultural production. Previous research has shown that advanced information on OAP and its climate implications could provide valuable opportunities to adjust agriculture practices. In this study, we review OAP effects on crop yields, covering both shorter-term El Niño Southern Oscillation (ENSO) and longer-term ocean-related decadal climate variability (DCV) phenomena, such as Pacific Decadal Oscillation (PDO), the Tropical Atlantic Gradient (TAG), and the West Pacific Warm Pool (WPWP). We review both statistical approaches and simulation models that have been used to assess OAP impacts on crop yields. Findings show heterogeneous impacts across crops, regions, OAP phases, and seasons. Evidence also indicates that more frequent and extreme OAP phases would damage agriculture. However, economic gains could be achieved via adaptation strategies responding to the early release of OAP phase information. Discussions on current knowledge gaps and future research issues are included.
