Linking farmers' perceptions and management decision toward sustainable agroecological transition: evidence from rural Tunisia.

Global food systems face sustainability challenges like undernourishment, inequity, resource degradation, and pollution. Food production and consumption drive environmental change with greenhouse gas emissions, biodiversity loss, and land-system shifts. The climate change crisis has intensified concerns about the ecological impact of these systems.

Prediction of intensive care unit mortality: Interest of serum lactates.

Introduction: Many prognostic indices have been developed to assess clinical status and predict the probability of death in the intensive care unit (ICU) but none have perfect sensitivity or specificity.

Aim: To evaluate the prognostic value of admission lactate in patients admitted to ICU.

Methods: A cohort, observational, prospective study was carried out in the intensive care unit (ICU) of Mongi Slim Hospital, la Marsa, over 12 months period.

Estimation of the economic loss due to irrigation water use inefficiency in Tunisia.

The main objective of this study is to estimate the total economic loss due to inefficient use of irrigation water in Tunisia. Several approaches have been used for this purpose. The optimal level of water application for different crops is calculated using the actual crop evapotranspiration which is based on FAO-56 method.
