Global agricultural responses to interannual climate and biophysical variability

Abstract: Most studies assessing climate impacts on agriculture have focused on average changes in market-mediated responses (e.g. changes in land use, production, and consumption). However, the response of global agricultural markets to interannual variability (IAV) in climate and biophysical shocks is poorly understood and not well represented in global economic models. Here we show a strong transmission of IAVs in climate-induced biophysical yield shocks to agriculture markets, which is further magnified by endogenous market fluctuations generated due to producers’ imperfect expectations of market and weather conditions. We demonstrate that the volatility of crop prices and consumption could be significantly underestimated (i.e. on average by 55% and 41%, respectively) by assuming perfect foresight, a standard assumption in the economic equilibrium modeling, compared with the relatively more realistic adaptive expectations. We also find heterogeneity in IAV across crops and regions, which is considerably mediated by international trade. Studying IAV provides fundamentally new insights on measuring and understanding climate impacts on global agriculture, and our framework lays the foundation for further investigating the full range of climate impacts on biophysical and human systems.

Fire plays a dominant role in deforestation, particularly in the tropics, but the relative extent of transformations and influence of fire frequency on eventual forest loss remain unclear. Here, we analyze the frequency of fire and its influence on postfire forest trajectories between 2001 and 2018. We account for ~1.1% of Latin American forests burnt in 2002–2003 (8,465,850 ha). Although 40.1% of forests (3,393,250 ha) burned only once, by 2018, ~48% of the evergreen forests converted to other, primarily grass-dominated uses. While greater fire frequency yielded more transformation, our results reveal the staggering impact of even a single fire. Increasing fire frequency imposes greater risks of irreversible forest loss, transforming forests into ecosystems increasingly vulnerable to degradation. Reversing this trend is indispensable to both mitigate and adapt to climate change globally. As climate change transforms fire regimes across the region, key actions are needed to conserve Latin American forests.

AIMES Thanks Scientists for Their Service

AIMES Thanks Scientists for Their Service

The AIMES scientific steering committee is comprised of volunteer scientists who go above and beyond their professional demands to help guide and build the AIMES international scientific program and network. We want to thank three of our steering committee members for their service-minded dedication, scientific vision, and commitment of time and energy over the course of their terms in AIMES. Victor Brovkin (Max Planck Institute for Meteorology, Germany), Lisa Alexander (University of New South Wales, Australia), and Govindasamy Bala (Indian Institute of Science, India) completed their final year of their terms in 2021. Below we highlight their research and contributions to the AIMES project!

Prof. Lisa Alexander, Professor at the Climate Change Research Centre, UNSW Sydney, Australia, served two terms as an AIMES SSC member. She made important contributions to the AIMES science plan and implementation plan and encouraged the inclusion of early career researchers in AIMES activities. Her research focuses primarily on understanding the variability and driving mechanisms of climate extremes, including how land surface changes or preconditioning might act to dampen or exacerbate heatwaves. Of particular significance is her ongoing work assessing global changes in temperature and rainfall extremes, which has contributed significantly to the Intergovernmental Panel on Climate Change (IPCC) assessments. 

Prof. Govindasamy Bala, Professor at the Center for Atmospheric and Oceanic Sciences, Indian Institute of Science, Bangalore, served two terms as an AIMES SSC member. Bala provided support and input in the new organization and scientific direction of AIMES and liaised with Future Earth as a working group leader within the Earth Commission. He is helping to organize a webinar series on ‘Tipping Elements, Irreversibility, and Abrupt Change’ and is co-leading the Tipping Point Model Intercomparison Project (TIPMIP). In his research, Prof. Bala develops and uses Earth system models to understand the causes and effects of climate change, and served as a Lead Author of the fourth chapter of Future global climate: scenario-based projections and near-term information for the 6th assessment IPCC report. 

Prof. Victor Brovkin is head of a group on Climate-Biogeosphere Interactions at the Max-Planck Institute for Meteorology and professor at the University of Hamburg, Germany. He served two terms as an AIMES SSC member and four years as the AIMES co-chair. Prof. Brovkin has been integral to many of the AIMES activities over the last four years including hosting SSC meetings, developing workshops, and leading the Nature Geoscience review on ‘Past abrupt changes, tipping points and cascading impacts in the Earth system.’ His research is focused on interactions between terrestrial ecosystems and the climate, including biogeophysical and biogeochemical feedbacks. Victor Brovkin has developed global dynamic vegetation models and applied them for pioneering studies on the stability of climate-vegetation systems.

We thank Lisa, Bala and Victor for their vision and for being fantastic colleagues to work with on the steering committee!

New Directions in Land Data Assimilation

2nd Annual Land Data Assimilation Community Virtual Workshop

13-15 June 2022 | 10:00-13:00 EDT // 16:00-19:00 CEST

The AIMES Land Data Assimilation Working Group will hold its 2nd annual workshop ‘New Directions in Land Data Assimilation’ on 13-15 June 2022 from 10:00 – 13:00 EDTThe goals of the workshop build on the principles of the working group to: (1) foster knowledge exchange across all groups working in land DA and (2) build a community of practice and collaboration in land DA, particularly for addressing the technical challenges we face in implementing DA systems. The themes of the workshop were identified by the land DA community during the 2021 meeting on Tackling Technical Challenges in Land DA and through feedback from a post-workshop survey.

We now invite abstract submissions for oral or poster presentations that address one of the following main themes: 

(1) Machine Learning in Land DA
(2) Observation and Model Uncertainty
(3) Ensemble DA methods
(4) Crossover in Land DA challenges between Numerical Weather Prediction and Land Surface Modeling communities
 

We are seeking abstracts that put greater weight on addressing the technical challenges associated with developing land DA systems than answering the scientific questions that lie behind those technical developments, which is typically the focus of other professional meetings and conferences. Oral presentations will prioritize the themes identified above. However, we will also consider abstracts that address important topics beyond the designated themes.

We are looking forward to continuing to build the land DA community and to seeing your abstracts! The deadline to submit your abstract is Friday, March 4, 2022. Email aimes@futureearth.org with any questions.
