We are excited to announce our October event! This month join us to hear from Elisabeth Vogel, a PhD student at the Australian-German Climate & Energy College at the University of Melbourne. Her research interests are centered on climate change impacts on ecological and human systems, with a particular focus on climate extreme events and agriculture. Within her PhD, Elisabeth investigates the impact of extreme weather events on global crop yields using a range of statistical methods. Before her PhD, Elisabeth completed a degree in Environmental Engineering at the Technical University of Berlin.
Title: Using random forests to better understand the impacts of climate extreme events on food production
Abstract: Climate extreme events, such as droughts or heatwaves – have a severe impact on agricultural productivity worldwide. It is important to understand how such extreme events have affected global food production in the past in order to increase the resilience of the global food system to such events in the future. In this presentation, I will talk about how random forests - a machine learning algorithm - can help to detangle the complex interactions between climate and agricultural variables. In the first part of this presentation, I will introduce the concept of random forests, how they are used for regression and classification problems and how to build random forests in R using the randomForest package. In the second part I will talk about how I applied random forests to global climate and agricultural datasets to look at how climate extreme events affected agricultural production.
This month is also R-Ladies Melbourne first anniversary! So be sure to come at 5:30pm for cake and bubbles to celebrate with us!
This month our event is taking place at the Walter and Eliza Hall Institute of Medical Research (WEHI) at 1G Royal Parade Parkville. To access WEHI please take note of the map and directions below.
An R-Ladies member will be waiting at the Gene Technology Access Centre entry to point you in the right direction.
Looking forward to see you all there!
