Application of artificial intelligence for nutrient estimation in surface water bodies of basins with intensive agriculture.
Integr Environ Assess Manag

División de Estudios de Posgrado e Investigación, Tecnológico Nacional de México/IT de Culiacán, Culiacán, Sinaloa, México.
Article Synopsis
- Eutrophication poses significant risks to water supply and food security, primarily driven by nitrogen and phosphorus levels in water, heightened by agricultural runoff.
- Machine learning methods like MLP, KNN, CNN, and RF are employed to estimate nutrient concentrations in surface waters of Sinaloa, using real-time data such as pH and dissolved oxygen instead of labor-intensive chemical analyses.
- Among these models, Random Forest showed the highest accuracy with an R² value of 0.85, indicating its potential for effective water quality management across various conditions in Sinaloa.
Science and technical priorities for private sector action to address biodiversity loss.

Target 15 of the Kunming-Montreal Global Biodiversity Framework recognizes the importance of the private sector monitoring, assessing and disclosing biodiversity-related risks, dependencies and impacts. Many businesses and financial institutions are progressing with science-based assessments, targets and disclosures and integrating into strategy, risk management and capital allocation decisions. Developments will continue in response to investor expectations, emerging corporate sustainability reporting regulations in Europe, China and elsewhere and evolving global sustainability reporting standards.

January 2025
Government of Alberta, Forestry and Parks Canmore Alberta Canada.
Article Synopsis
- Wolverines have faced significant range reduction globally, with complete extirpation from eastern Canada and some western prairie regions.
- In Alberta, where they are designated for conservation, researchers aimed to estimate wolverine abundance using existing density data and habitat relationships.
- Results indicated approximately 955 wolverines in the province, with only 544 classified as adults, suggesting a need for a reassessment of their conservation status and related protective measures.
The probability of detecting host-specific microbial source tracking markers in surface waters was strongly associated with method and season.

Fecal contamination of surface waters presents significant human health and environmental risks. While many methods for understanding fecal contamination cannot differentiate between human and animal sources, microbial source tracking (MST) marker methods are used to identify fecal sources. To understand how to best employ MST marker data for managing fecal contamination risks, the present study compiled previously collected MST marker data ( = 12,878 samples) from across North America; each sample in the data set had been tested for fecal contamination from one or more of five sources (avian, canine, human, ruminant, swine).

Food allergy is a significant public health concern and food safety issue. Deriving from classical toxicology principle, the food allergen risk assessment has been considered a science-based strategy to identify, quantify, and manage the food allergy risks as such risk represent a significant food safety. Moreover, the implication of the precautionary allergen labeling in most jurisdictions is voluntary, resulting potential risk to allergic consumers.
