The genus Alphavirus harbors arboviruses of great concern, such as the Chikungunya virus and the equine encephalitis viruses. Transmission of pathogenic alphaviruses by mosquitoes could be influenced by insect-specific alphaviruses such as Eilat virus (EILV). However, insect-specific alphaviruses are rarely found in wild mosquitoes and only a few have been described in the literature.

Animal-sourced foods improve child nutrition in Africa.

Proc Natl Acad Sci U S A

December 2024

Center for Development Research (ZEF), University of Bonn, Bonn 53113, Germany.

Child undernutrition remains a widespread public health problem in the Global South, especially in Africa. Childhood stunting-meaning linear growth retardation-is a comprehensive and commonly used indicator of chronic child undernutrition and is mostly the result of insufficient nutrient intake, among other factors. Previous research showed that the consumption of animal-sourced foods (ASF), including meat, dairy, eggs, and fish, is associated with lower rates of child stunting, but reliable evidence for Africa is scant.

Urban green infrastructure (GI) plays a crucial role in improving air quality by removing pollutants and reducing emissions from structures. However, in Ethiopia, inadequate GI planning, largely due to limited awareness among planners and policymakers, can undermine the benefits of GI and worsen urban air quality issues. In this study, we demonstrate how the GI strategy approach can enhance air quality and assess the negative impacts of biogenic volatile organic compounds (BVOCs) emitted by certain tree species in Ethiopia, using Hawassa as a case study.

Assessing long-term water storage dynamics in Afghanistan: An integrated approach using machine learning, hydrological models, and remote sensing.

J Environ Manage

November 2024

Key Laboratory of Earth System Numerical Modeling and Application/College of Earth and Planetary Sciences, University of Chinese Academy of Sciences, Chinese Academy of Sciences, Beijing, China.

Assessment of Terrestrial Water Storage (TWS) components is crucial for understanding regional climate and water resources, particularly in arid and semi-arid regions like Afghanistan. Given the scarcity of ground-based data, this study leverages remote sensing datasets to quantify water storage changes. We integrated Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-on (GRACE-FO) data with WaterGap, Global Land Water Storage (GWLS), Catchment Land Surface Model (CLSM), and climate variables (precipitation, temperature, potential evapotranspiration) using artificial neural networks (ANN) and random forests (RF).

Article Synopsis
  • This study developed a Sustainable Diet Index (SDI) to assess the sustainability of diets among adults in Ghana and Ghanaian migrants in Europe, focusing on factors like health, climate impact, cultural values, and cost.
  • Using data from 3,169 participants aged 25-70, the SDI ranged from 0 to 16 and utilized various dietary metrics, showing an overall mean SDI of 8.0.
  • Results indicated that higher SDI scores were linked to older age, female gender, non-smoking, and alcohol abstinence, with the highest SDI found in London (9.1), suggesting that living in Europe generally leads to more sustainable dietary practices compared to rural Ghana.

Humans tend to give more weight to information confirming their beliefs than to information that disconfirms them. Nevertheless, this apparent irrationality has been shown to improve individual decision-making under uncertainty. However, little is known about this bias' impact on decision-making in a social context.

Environmental impacts of genetically modified crops.

Science

August 2024

Institute for Resources, Environment and Sustainability, University of British Columbia, Vancouver, BC, Canada.

Article Synopsis
  • GM crops are widely used in leading agricultural countries, but their overall environmental effects are still not fully understood.
  • The decline in direct concerns about GM crops has led to significant indirect changes in farming practices, affecting pesticide usage, land expansion, and crop rotations, all of which impact the environment.
  • Recent research shows that the effects of GM crops on biodiversity, deforestation, and human health are complex and vary based on specific traits and the geographic context of their use.

Government policies for marine fisheries have been implemented in Cabo Verde since its independence in 1975, with the aim to prevent overexploitation of wild fish species and promote sustainable fishing practices. Nonetheless, only minor amendments have been made to the legal harvesting size, considering biological sciences. This study, therefore, adopted a transdisciplinary approach to assess the political, ecological, and social dimensions of current fishery policy interventions applicable to the commercially valuable pelagic species Decapterus macarellus (mackerel scad).

Positive public attitudes towards agricultural robots.

Sci Rep

July 2024

Center for Development Research (ZEF), University of Bonn, Bonn, Germany.

Robot technologies could lead to radical changes in farming. But what does the public know and think about agricultural robots? Recent experience with other agricultural technologies-such as plant genetic engineering-shows that public perceptions can influence the pace and direction of innovation, so understanding perceptions and how they are formed is important. Here, we use representative data from an online survey (n = 2269) to analyze public attitudes towards crop farming robots in Germany-a country where new farming technologies are sometimes seen with skepticism.
