ELM’s Response: Annotated Bibliography: Impacts of Climate Change on Agriculture Climate change poses a significant threat to agriculture due to changing patterns in weather, increased frequency of extreme weather events, and shifts in pest and disease dynamics. The following annotated bibliography highlights three scholarly sources examining the contemporary impacts of climate change on agriculture, relevant up-to-date statistics, and key technologies being developed or utilised in this context. Source 1: Lobell, D. B., Schlenker, W., & Costa-Roberts, J. (2011). "Climate Trends and Global Crop Production Since 1980." Science, 333(6042), 616-620. doi:10.1126/science.1204531 Summary: Lobell et al.'s seminal paper assesses the impact of climate trends on global crop yields since 1980. The study utilises a comprehensive dataset to analyse the correlation between climate variables and agricultural productivity, focusing on staple crops like wheat, rice, maize, and soybeans. The authors find that temperature increases and changing precipitation patterns have caused significant yield reductions in some regions, particularly in tropical and subtropical areas. Relevance: Despite being published in 2011, this article remains highly relevant for understanding the historical impacts of climate change on agriculture. It sets the foundation for identifying trends and projecting future impacts. The methodology and data analysis techniques employed in this study are essential for current researchers aiming to compare historical data with recent trends. Source 2: Zhao, C., Liu, B., Piao, S., Wang, X., Lobell, D. B., Huang, Y., ... & Asseng, S. (2017). "Temperature increase reduces global yields of major crops in four independent estimates." Proceedings of the National Academy of Sciences, 114(35), 9326-9331. doi:10.1073/pnas.1701762114 Summary: This study quantifies the impact of global temperature increases on the yields of four major crops: maize, wheat, rice, and soybean. Zhao et al. use four different statistical models and datasets to provide robust estimates of yield sensitivity to temperature changes. The study concludes that each degree Celsius increase in global mean temperature is associated with an average reduction in global yields of 6.0% for wheat, 3.2% for rice, 7.4% for maize, and 3.1% for soybean. Relevance: This article provides a detailed and up-to-date quantification of the impacts of temperature increases on agriculture, corroborated by multiple models and datasets. It is beneficial for researchers needing current statistical data on crop yield sensitivity and those evaluating the effectiveness of adaptation strategies on a global scale. Source 3: Rosegrant, M. W., & Cline, S. A. (2003). "Global Food Security: Challenges and Policies." Science, 302(5652), 1917-1919. doi:10.1126/science.1092958 Summary: Rosegrant and Cline discuss the broader implications of climate change on global food security by integrating biophysical and socio-economic models. The article highlights the potential for technological innovations and policy interventions to mitigate the adverse effects of climate change on food production systems. Key technologies explored include genetic modifications for stress tolerance, improved water management practices, and sustainable intensification methods. Relevance: This source is vital for understanding the intersection of climate change impacts, food security, and technological innovation. It provides insights into policy recommendations and technological advancements necessary to sustain agricultural productivity under changing climatic conditions. Researchers and policymakers can draw on this paper to explore integrated approaches to enhance resilience in food systems. Conclusion The compiled sources offer a robust foundation for understanding the historical and current impacts of climate change on agriculture, presenting valuable statistical analyses and discussing adaptive technologies and policies. Collectively, these studies underpin the urgent need for innovative solutions and coordinated global efforts to ensure sustainable agricultural production in the face of climate change.
