Summary: A long‐standing debate looks at whether air or soil dryness is more limiting to vegetation water use and productivity. The answer has large implications for future ecosystem functioning, as atmospheric dryness is predicted to increase globally while changes in soil moisture are predicted to be far more variable. Here, I review the complexities that contribute to this debate, including the strong coupling between atmospheric and soil dryness, and the widespread heterogeneity in vegetation hydraulic traits, acclimations, and adaptations to water stress. I discuss solutions to improve understanding and modeling of vegetation sensitivity to dryness, including how different types of observational data can be used together to gain insight into vegetation response to water stress across spatial and temporal scales.

Dryland ecosystems cover 40% of our planet's land surface, support billions of people, and are responding rapidly to climate and land use change. These expansive systems also dominate core aspects of Earth's climate, storing and exchanging vast amounts of water, carbon, and energy with the atmosphere. Despite their indispensable ecosystem services and high vulnerability to change, drylands are one of the least understood ecosystem types, partly due to challenges studying their heterogeneous landscapes and misconceptions that drylands are unproductive "wastelands." Consequently, inadequate understanding of dryland processes has resulted in poor model representation and forecasting capacity, hindering decision making for these at‐risk ecosystems. NASA satellite resources are increasingly available at the higher resolutions needed to enhance understanding of drylands' heterogeneous spatiotemporal dynamics. NASA's Terrestrial Ecology Program solicited proposals for scoping a multi‐year field campaign, of which Adaptation and Response in Drylands (ARID) was one of two scoping studies selected. A primary goal of the scoping study is to gather input from the scientific and data end‐user communities on dryland research gaps and data user needs. Here, we provide an overview of the ARID team's community engagement and how it has guided development of our framework. This includes an ARID kickoff meeting with over 300 participants held in October 2023 at the University of Arizona to gather input from data end‐users and scientists. We also summarize insights gained from hundreds of follow‐up activities, including from a tribal‐engagement focused workshop in New Mexico, conference town halls, intensive roundtables, and international engagements. Plain Language Summary: Drylands are landscapes with limited water availability, which cover 40% of Earth's land surfaces, support billions of humans, and play a substantial role in Earth's weather and climate systems. However, these ecosystems are under threat from droughts and heatwaves. They are also poorly understood because of challenges measuring their highly diverse vegetation types and interspersed vegetation cover and because of incorrect perceptions that they are unimportant "wastelands." These limitations make it challenging to manage their landscapes and quantify how drylands are driving Earth's weather and climate. NASA solicited proposals for a multi‐year field campaign, of which Adaptation and Response in Drylands (ARID) was one of two scoping studies selected. The ARID scoping study aims to design a plan for how NASA satellite, aircraft, and field instruments can be used to better understand dryland ecosystems and their response to change. A primary scoping goal is to engage with scientists and data‐users, especially those who manage land, to understand research and management priorities in drylands. Here, we discuss details of our meeting with over 300 scientists and data‐users in Tucson, AZ in October 2023. We also highlight feedback from our tribal‐focused workshop in New Mexico, conference town halls, and international meetings. Key Points: Adaptation and Response in Drylands (ARID) is a 1‐year scoping study for a multi‐year NASA Terrestrial Ecology dryland field campaignAn ARID workshop was held in Tucson, Arizona in October 2023 with more than 30 data end‐users and 300 scientists in attendanceFurther input from hundreds of researchers and end‐users was obtained through workshops, conference townhalls, and tribal engagement [ABSTRACT FROM AUTHOR]

The Australian Bragg Centre for Proton Therapy and Research (ABCPTR) established the Bragg Consumer Advisory Group (BCAG) in 2023. The ABCPTR, being the first of its kind in Australia, will offer proton therapy treatment for challenging solid tumours with the potential to reduce radiationinduced side effects. With over 110 Proton Beam Therapy (PBT) centres globally, Australian patients currently can apply to access government funded treatment overseas, however, international travel for treatment presents various, significant challenges. Consumer engagement in healthcare plays a pivotal role in navigating the multifaceted journey of cancer treatment and can complement cancer control strategies by ensuring the practicalities of the cancer journey are realised. The ABCPTR aims to involve consumers in decision-making processes, especially as it prepares to open Australia's first national proton therapy centre. The aim of this commentary is to highlight the importance of involving consumers in cancer care, and to demonstrate how this was done in Australia's first proton therapy centre. To establish a consumer engagement team, ABCPTR utilised existing clinical staff. The team's formation and upskilling were integral to the project's success. The engagement framework was developed based on the five stages of commitment by the Australian Health Research Alliance and Western Australian Health Translation Network. The ABCPTR consumer engagement team successfully created a community engagement framework and upskilled in consumer engagement principles over 9-12 months. An Expression of Interest (EOI) was launched, resulting in the formation of the BCAG comprising of 10 members with diverse backgrounds and experiences. The BCAG has been actively involved in decision-making processes, with a consumer-led chair and co-chair in place. The group's feedback is expected to influence key performance indicators for the centre. The establishment of the BCAG at the ABCPTR emphasises the importance of integrating patient and community perspectives into clinical initiatives. This proactive approach ensures that processes remain patient-centred. The ongoing multi-level consumer engagement strategy aims to shape a more inclusive approach to cancer care in Australia, especially concerning PBT. [ABSTRACT FROM AUTHOR]

FOREST resilience ,RAIN forests ,ECOLOGICAL disturbances ,DEFORESTATION ,FOREST canopy gaps - Abstract
Uncovering the mechanisms that lead to Amazon forest resilience variations is crucial to predict the impact of future climatic and anthropogenic disturbances. Here, we apply a previously used empirical resilience metrics, lag‐1 month temporal autocorrelation (TAC), to vegetation optical depth data in C‐band (a good proxy of the whole canopy water content) in order to explore how forest resilience variations are impacted by human disturbances and environmental drivers in the Brazilian Amazon. We found that human disturbances significantly increase the risk of critical transitions, and that the median TAC value is ~2.4 times higher in human‐disturbed forests than that in intact forests, suggesting a much lower resilience in disturbed forests. Additionally, human‐disturbed forests are less resilient to land surface heat stress and atmospheric water stress than intact forests. Among human‐disturbed forests, forests with a more closed and thicker canopy structure, which is linked to a higher forest cover and a lower disturbance fraction, are comparably more resilient. These results further emphasize the urgent need to limit deforestation and degradation through policy intervention to maintain the resilience of the Amazon rainforests. [ABSTRACT FROM AUTHOR]
