Microbiological guideline values for recreational bathing in Canada: Time for change? [PDF]
Can J Infect Dis Med Microbiol, 2007 Recreational bathing is an activity practiced by thousands of Canadians every year. While its health benefits are numerous, bathing in polluted water can also be a source of health problems. These problems are generally nonspecific and are difficult to detect through usual health monitoring systems.

Evaluation of new pivoting linear‐move precision irrigation machine
Irrigation and Drainage, Volume 72, Issue 4, Page 922-933, October 2023., 2023 Abstract Due to population growth, freshwater resources around the world are becoming increasingly scarce, and the water supply in agriculture has emerged as one of the limitations of food production. Variable‐rate irrigation (VRI), a type of precision irrigation, allows water‐efficient irrigation techniques to ensure an optimal water supply.

Muddy waters: Mega‐herbivores as agents of change in African shallow freshwaters
African Journal of Ecology, Volume 61, Issue 3, Page 722-725, September 2023., 2023 Abstract Large herbivores have been described as agents of change in terrestrial habitats. Their effect on aquatic ecosystems are, however, underexplored. We raise the question of whether elephants and hippopotamus have the potential to significantly alter limnological properties and, indirectly, primary and secondary productivity within small and ...

Irrigation and Drainage, Volume 71, Issue S1, Page 100-109, October 2022., 2022 Abstract The impact of climate change on the availability of water affects all types of land use and sectors. This complexity calls for integrated water resources management and negotiations between sectors on the most important, cost‐effective, and productive allocation of water where it is a limited resource.

Viewpoint: Irrigation water management in a space age
Irrigation and Drainage, Volume 71, Issue S1, Page 39-50, October 2022., 2022 Abstract Climate change and rapid population growth are already putting increasing demand and pressure on the world's freshwater resources. Irrigated agriculture is responsible for about 70% of global freshwater withdrawals, consuming the most amount of water.

Knowledge and Management of Aquatic Ecosystems, 1998 Lors d'une étude antérieure, nous avons montré que le maintien en mer des Saumons atlantiques mâles affecte la qualité du sperme. Pour tester l'hypothèse de l'influence néfaste d'une contamination par l'urine, nous avons comparé la qualité du sperme ...
