Energy and food security implications of transitioning synthetic nitrogen fertilizers to net-zero emissions

Lorenzo Rosa et al.

Summary: The Haber-Bosch process, which synthetically produces nitrogen fertilizers from ammonia, has been sustaining humanity for over a century. However, the current production heavily relies on fossil fuels, resulting in high energy consumption and carbon emissions. This poses a challenge to climate goals and creates a dependency on fossil fuels for agricultural production. The study reveals that a significant number of people, approximately 1.78 billion, rely on imported nitrogen fertilizers or natural gas for food production, exposing the vulnerability of global food production to supply and energy shocks. Alternative routes to achieve net-zero emissions in NH3 production, such as carbon capture and storage, electrification, and biomass, offer potential solutions to climate and food security concerns, but these routes require additional land, energy, and water resources.

Attachment in close relationships and glycemic outcomes in children with type 1 diabetes

Simona Klemencic et al.

Summary: This study aimed to explore the relationship between child attachment to parents, parent attachment style, morning cortisol levels, and diabetes outcomes in children with type 1 diabetes. The results showed that securely attached girls had higher average HbA1c levels, while boys with insecurely attached parents had worse glycemic outcomes.

Spatially differentiated nitrogen supply is key in a global food-fertilizer price crisis

Sieglinde Snapp et al.

Summary: Fertilizer supply is crucial for global food security, but it is vulnerable to international disruptions. To address nitrogen fertilizer price spikes and threats to food security, differentiated responses are needed, including integrated management of organic and inorganic nitrogen sources. This can lead to potential fertilizer savings and improved nutrient utilization in both high-input and low-input cereal production systems.

Reversing Years for Global Food Security: A Review of the Food Security Situation in Sub-Saharan Africa (SSA)

Abdulazeez Hudu Wudil et al.

Summary: Inequalities persist in factors affecting food security outcomes worldwide, and especially in Sub-Saharan Africa where weak economic growth, gender inequality, climate change, and other challenges hinder progress. Investing in agricultural infrastructure, promoting gender equality, and addressing the impacts of climate change are crucial for improving food security in the region.

Ammonia and Nitric Acid Demands for Fertilizer Use in 2050

Jeonghoon Lim et al.

Summary: Access to nitrogen-based fertilizers is crucial for maximizing agricultural yield, but the production process contributes significantly to carbon emissions. The market size and value of ammonia and nitric acid will be heavily influenced by the growing global population and food demand over the next three decades. Developing carbon-free technologies for nitrogen and nitrate reduction to meet fertilizer manufacturing demands is essential to address the environmental impact of current production methods.

Mapping access to basic hygiene services in low- and middle-income countries: A cross-sectional case study of geospatial disparities

Weiyu Yu et al.

Summary: Handwashing with water and soap is a cost-effective way to improve public health, but billions of people worldwide lack access to handwashing facilities. A machine learning model was developed to predict the prevalence of basic hygiene facilities in several countries, revealing disparities in access across different geographic regions and between urban and rural areas. Educational attainment and wealth were found to be important predictors of the distribution of basic hygiene services.

Sanitized human urine (Oga) as a fertilizer auto-innovation from women farmers in Niger

Hannatou O. Moussa et al.

Summary: Poor soil fertility and climate change limit pearl millet grain yield in Niger. By using sanitized human urine and organic manure, pearl millet panicle yield in women's fields can be increased effectively. This innovative method is affordable and feasible for resource-poor female farmers in Niger.

Defining Nutrient Colocation Typologies for Human-Derived Supply and Crop Demand To Advance Resource Recovery

Desarae Echevarria et al.

Summary: Analysis of the colocation of human-derived nutrients and crop demands in 107 countries revealed three typologies, which can inform resource recovery management strategies, policy, and investment. Principal component analysis showed a clustering of Human Development Index by typology, indicating a connection between resource recovery patterns and country-specific contextual characteristics.

Global nutrient equity for people and the planet

Helena Kahiluoto et al.

Summary: Global redistribution of accumulated nutrients can enhance food security and counteract degradation of critical Earth system processes by trading accumulated nutrient rights through a 'one Earth currency'. Processing residue and sediment nutrients can help meet the needs of food-insecure regions, triggering required innovations in processing, logistics, and thinking.

Fertilizer and grain prices constrain food production in sub-Saharan Africa

Camila Bonilla-Cedrez et al.

Summary: Farmers in sub-Saharan Africa would need to use more fertilizers to increase crop yields, but the fertilizer and maize price ratio poses a strong barrier in most regions. Closing the 'ecological yield gap' is considered important for food security, but there may be weak economic incentives for farmers to substantially increase yields. Agricultural intensification could be supported by complementary agronomic approaches to improve soil fertility and lower fertilizer costs.

Quantification of global and national nitrogen budgets for crop production

Xin Zhang et al.

Summary: Input-output estimates of nitrogen on cropland are essential for improving nitrogen management and understanding the global nitrogen cycle. While most datasets show similar patterns, some annual estimates vary widely, leading to large ranges of uncertainty. The comparison of nitrogen budget terms by country reveals areas for improvement.
