Farming on the edge: assessing the impact of historical and future climate change on the mediterranean cropping margins of Australia Open
The boundary between land suitable for low rainfall grain cropping and the arid interior suitable for extensive grazing has a history in South Australia dating back to Goyder in the 1860s and in Western Australia to Brookman in the 1900s. …

Detection and attribution of cereal yield losses using Sentinel-2 and weather data: A case study in South Australia Open
Weather extremes affect crop production. Remote sensing can help to detect crop damage and estimate lost yield due to weather extremes over large spatial extents. We propose a novel scalable method to predict in-season yield losses at the …

Sub-field detection of cereal yield losses and its causes using Sentinel-2 time series and weather data Open
Weather extremes severely affect agricultural production and threaten food security worldwide. Throughout the growing season, crops can experience various degrees of weather stress whereby multiple stressors could occur simultaneously or i…

Focus on the future of water-limited agricultural landscapes Open
Water scarcity and related climate volatility are growing constraints on agricultural production landscapes around the world. While the adaptation options available are often dictated by system context, in many places broad-scale transform…

Overcoming barriers to social inclusion in agricultural intensification: reflections on a transdisciplinary community development project from India and Bangladesh Open
We describe a research-for-development (R4D) strategy developed to address how investments and interventions in agricultural intensification as a means to achieve community development can be designed to be more socially inclusive and equi…

Climate change shifts agropastoral-pastoral margins in Africa putting food security and livelihoods at risk Open
Climate is one of the key factors determining the suitability of land for agricultural production and influencing the spatial transition between grazing and cropping-dominated farming systems in Africa. We identified the climate indices th…

Integrating gender and farmer's preferences in a discussion support tool for crop choice Open
In northern West Bengal and southern Bangladesh, Rabi crops, sown in winter and harvested in the spring, are an important source of income and nutrition for the target communities. In the study areas, NGOs and extension services have been …

Minimum temperature mapping augments Australian grain farmers’ knowledge of frost Open
Economic losses due to crop damage caused by frost in Australia are estimated to be many hundreds of millions of dollars. In broadacre cropping, pre-sowing management to alleviate frost risk, and timely post-frost decisions rely on locally…

Climate Risk Management in Smallholder Farming Systems in the Semiarid Tropics Open
Climate risk management in the semi-arid tropics (SAT) is one of the major challenges to achieving food security and development in India and large parts of sub-Saharan Africa and also in the case of Australia. Climate-induced production r…

Modelling frost generates insights for managing risk of minimum temperature extremes Open
Frosts and extreme minimum temperature events cause significant damage to grapevines. In the Victorian vine growing regions of Australia, these events may cause complete wipe-out of a season's grape production, and millions of dollars of l…

Linking climate forecasts to rural livelihoods: Mapping decisions, information networks and value chains Open
Climate variability is a key source of livelihood risks faced by smallholder farmers in drier environments in many developing countries. Climate information provided on seasonal time-scales can sometimes improve agricultural decision-makin…
