Understanding the magnitude and importance of income shocks, such as drought or conflict, in causing and perpetuating poverty is critical to designing policies aimed at building resilience and contributing toward the goal of ending poverty.
This BAMS special report presents assessments of how human-caused climate change may have affected the strength and likelihood of individual extreme events. This is the second year that scientists have identified extreme weather events that they said could not have happened without warming of the climate through human-induced climate change.
The report, “Deluge & Drought: Water Security in a Changing Climate”, has found the severe drought gripping much of Australia has been exacerbated by climate change. Australia’s water security has already been significantly influenced by climate change.
This paper provides a background to the issues and current research surrounding drought in a changing climate. The publication draws insight from a dialogue with practitioners and researchers from a variety of New Zealand organisations involved in areas where climate-driven changes to drought risk are pertinent for long-term planning.
The 2015/2016 El Niño event caused severe changes in precipitation across the tropics. This impacted surface hydrology, such as river run-off and soil moisture availability, thereby triggering reductions in gross primary production (GPP).
