The disruptions in food systems caused by extreme events have repeatedly challenged food security at multiple levels. Recently, the COVID-19 pandemic has exacerbated the vulnerabilities of existing global food systems and has resulted in food stress for an additional 145 million people. This paper addresses the critical need for enacting and strengthening policies targeted at securing food systems to achieve the Sustainable De...

Seasonal precipitation forecasting is vital for weather-sensitive sectors. Global Circulation Models (GCM) routinely produce ensemble Seasonal Climate Forecasts (SCFs) but suffer from issues like low forecast resolution and skills. To address these issues in this study, we introduce a post-processing method, Quantile Ensemble Bayesian Model Averaging (QEBMA). It utilises quantiles from a GCM ensemble forecast to create a pseud...

Climate change undermines the foundations of food and nutrition security, making it crucial to understand and improve the current research collaborations striving to fill knowledge gaps about the impacts on food systems. This study focuses on the network of research actors working on food systems and climate change in Pacific Island Countries and Territories (PICTs), a region particularly vulnerable to climate change, and acti...

Food security, in the context of a rapidly changing climate, is one of the most prominent global challenges facing human societies today. Pacific Island Countries and Territories (PICTs) are particularly vulnerable to the adverse effects of climate change, while facing additional stress from globalisation and increased supply chain disruption. This review aims to document our understanding of food system vulnerability to clima...

This study documents the importance, and changes in the importance, of a suite of synoptic to large‐scale drivers of minimum temperature variability across the Australian region. The drivers investigated are the El Niño – Southern Oscillation (ENSO) as measured by the Southern Oscillation Index, atmospheric blocking, the Southern Annular Mode, and the position and intensity of the subtropical ridge. In most regions, individual...

Despite a broad pattern of warming in minimum temperatures over the past 50 years, regions of southeastern Australia have experienced increases in frost frequency in recent decades, and more broadly across southern Australia, an extension of the frost window due to an earlier onset and later cessation. Consistent across southern Australia is a later cessation of frosts, with some areas of southeastern Australia experiencing th...
