Earlier famine warning possible using remote sensing and models

Remote sensing allows scientists to detect slowly evolving natural hazards such as agricultural drought. Famine early warning systems transform these data into actionable policy information, enabling humanitarian organizations to respond in a timely and appropriate manner. These life-saving responses are increasingly important: In 2006, one out of eight people did not have enough food to eat and 2

Climate risk and food security in Mali: A historical perspective on adaptation

We combine socioeconomic data from a large-scale household survey with historical climate data to map the climate sensitivity of availability and access dimensions of food security in Mali, and infer the ways in which at-risk communities may have been impacted by persistent climatic shift. Thirty years after 1982–1984, the period of most intense drought during the protracted late 20th century dryi

A methodological framework for rapidly assessing the impacts of climate risk on national-level food security through a vulnerability index

This article describes an experimental Hunger and Climate Vulnerability Index showing the relative vulnerability of food insecure populations to climate risks at country level, as a tool for better understanding risks to food security presented by climate change. Data from socioeconomic and environmental indicators were analysed, and the most relevant indicators were aggregated using a composite i

The abortion divide: Exploring the role of exclusion, loss of significance and identity in the radicalization process

Introduction: Recently, the abortion issue has entered the spotlight in the USA, leading to potential radical actions. As the majority opinion on the abortion issue vary with state, some individuals will be in the numerical minority within their state, possibly evoking feelings of exclusion. Social exclusion can motivate a radicalization process. The aim of this paper is to explore how individuals

Food Systems at Risk: Transformative Adaptation for Long-Term Food Security

This report examines how climate change is impacting agriculture and threatening national and global food systems, particularly in climate hotspots, and how these trends are projected to intensify over the coming decades. The report defines and details transformative adaptation for agriculture and why such longer-term, systemic approaches are needed to protect the lives and livelihoods of millions

A highly sensitive bead-based flow cytometric competitive binding assay to detect SARS-CoV-2 neutralizing antibody activity

Accurate detection of SARS-CoV-2 neutralizing antibody (nAb) is critical for assessing the immunity levels after virus infection or vaccination. As fast, cost-effective alternatives to viral infection-based assays, competitive binding (CB) assays were developed to quantitate nAb by monitoring the ability of sera to inhibit the binding of viral spike (S) protein to the angiotensin converting enzyme

Contingency planning and humanitarian action: a review of practice

This paper explores the current process and practice of contingency planning in humanitarian organisations. It sets out the key terms and concepts relating to contingency planning, explores the contingency planning process, explains the main models used by humanitarian organisations and presents a new concept of the process that enables a more dynamic approach than previous frameworks.The paper al

From rain to famine: assessing the utility of rainfall observations and seasonal forecasts to anticipate food insecurity in East Africa

East Africa experiences chronic food insecurity, with levels varying from year-to-year across the region. Given that much can be done to prevent this level of suffering before it happens, humanitarian agencies monitor early indicators of food insecurity to trigger early action. Forecasts of total seasonal rainfall are one tool used to monitor and anticipate food security outcomes. Factors beyond r

Forecasting, hazards, averting disasters: Implementing forecast-based early action at scale

Forecast-based early action (FbA) initiatives are diverse, with very different approaches to the timing of decisions and actions, and to the types of forecast, monitoring data and delivery mechanisms used. They are also increasingly of interest to donors and humanitarian agencies as they consider how to reduce the growing humanitarian burden and reconsider how aid is spent. FbA programming uses fo

Sedimentary molybdenum and uranium : Improving proxies for deoxygenation in coastal depositional environments

Sedimentary molybdenum (Mo) and uranium (U) enrichments are widely used to reconstruct changes in bottom water oxygen conditions in aquatic environments. Until now, most studies using Mo and U have focused on restricted suboxic-euxinic basins and continental margin oxygen minimum zones (OMZs), leaving mildly reducing and oxic (but eutrophic) coastal depositional environments vastly understudied. C

Cryptococcal Hsf3 controls intramitochondrial ROS homeostasis by regulating the respiratory process

Mitochondrial quality control prevents accumulation of intramitochondrial-derived reactive oxygen species (mtROS), thereby protecting cells against DNA damage, genome instability, and programmed cell death. However, underlying mechanisms are incompletely understood, particularly in fungal species. Here, we show that Cryptococcus neoformans heat shock factor 3 (CnHsf3) exhibits an atypical function

Semiarid ecosystems

• Semiarid regions control a large fraction of the interannual variability in the global terrestrial CO2 sink and of atmospheric CO2 growth rate. • Semiarid ecosystems are characterized by recurring disturbances that alter the regional C budgets. As disturbances are expected to become more frequent or intense in the future, quantifying their contribution to semiarid C balance is crucial. • We revi

Increased rates of fragrance allergy in fibromyalgia individuals tested with the Swedish baseline patch test series

Background: Contact allergy can manifest in a variety of ways clinically. Systemic contact allergy may occasionally present with pain in muscles and joints. Fibromyalgia is a chronic rheumatic disease characterized by pain and with virtually unknown aetiology. Objectives: The aim of this study was to investigate the contact allergy rates to the sensitizers in a baseline series and compare with cor

Moral Responsibility and Existential Attitudes

We might describe the philosophical issue of human freedom and moral responsibility as an existential metaphysical problem. Problems of this kind are not just a matter of theoretical interest and curiosity: They address issues that we care about and that affect us. They are, more specifically, relevant to the significance and value that we attach to our lives and the way that we lead them. Accordi

Adoption barriers for sustainable packaging practices : A comparative study of food supply chains in South Africa and Sweden

Packaging can play a key role in reducing food waste and enabling resource efficient logistics operations. This paper offers insights into why this potential is not fully adopted by companies in food supply chains by exploring adoption barriers for sustainable packaging practices in ten companies in South Africa and Sweden. The paper develops an analytical framework from theory and applies it to t

On nanosecond plasma-assisted ammonia combustion : Effects of pulse and mixture properties

In this study, the effects of nanosecond plasma discharges on the combustion characteristics of ammonia are investigated over a wide range of mixture properties and plasma settings. The results reveal that the impacts of the plasma on ammonia combustion change non-monotonically by altering the reduced electric field value. Within the studied range of the reduced electric field, i.e., 100–700 Td, i
