Improved generality of wheat green LAI models through mitigation of the effect of leaf chlorophyll content variation with red edge vegetation indices
No full textInternational audienceThe retrieval of wheat green leaf area index (LAIG) from satellite imagery is critical for monitoring crop growth and assessing food security. Numerous vegetation indices (VIs) derived from spectral reflectance have been widely used to estimate LAIG. In particular, red edge VIs can mitigate the confounding effect of multiple factors, such as the soil background and leaf inclination angle variation, and typically are highly correlated with LAIG. However, their relationship to LAIG tends to be affected by variations in leaf chlorophyll content (LCC), because the position of the red edge of vegetation spectra shifts with changes in LCC. This issue directly limits the operational use of VI-LAIG models, especially those employing red-edge bands. Therefore, to reduce the sensitivity of VI-LAIG relationships to LCC variation, this study proposed an innovative approach, called the Difference Combination between Spectral Indices (DCSI). Using synthetic data simulated with the PROSAIL radiative transfer model, we tested the dependence of the algebraic difference between common VIs on LCC. The results show that many combinations of VIs are insensitive to LCC variation. The newly developed DCSI combination between the Sentinel-2 red edge position (S2REP) and B6-red edge band (RE2) (i.e., DCSI(S2REP&RE2)), produces the most accurate LAIG model when LCC varies. We also modified the constant of this DCSI combination, to develop the Sentinel-2 modified red edge position (S2MREP) for LAIG retrievals. In comparison to traditional VI-LAIG models, the S2MREP-LAIG model has higher accuracy, with Rcal2 of 0.76 in calibration, and in validation Rval2 of 0.72 and RRMSE of 23.61 %. In addition, the S2MREP-LAIG model (RRMSE=28.64 %) also outperforms the existing Sentinel-2 LAI product (RRMSE=38.20 %) in the retrieval of wheat LAIG. In summary, the proposed DCSI approach and S2MREP effectively mitigate the impact of LCC variations on LAIG retrievals, thus facilitating the large-scale retrieval of LAIG and the spatial mapping of wheat LA

Monitoring Olive Tree and Identifying Olive-Growing Formation Using Very High Satellite Imagery : A Case Study of the Ouezzane Province in Morocco
No full textInternational audienceIn Morocco, olive groves are a predominant feature of many agricultural landscapes, resulting from both a long agricultural history and more recent national programs such as the Green Morocco Plan Plan Maroc Vert. Within this context, the ClimOliveMed and Future for Olive projects aimed to test a deliberative approach involving scientists, farmers, and olive sector stakeholders to identify desirable solutions and future scenarios for olive cultivation. From an environmental perspective, the project pursued two main objectives: (i) to identify the different types of olive groves, and (ii) to assess whether environmental factors such as -- topography -- influence their spatial distribution. Using very high resolution Pléiades satellite imagery 2023, we developed a methodology combining supervised classification with spatial analysis based on geometric features, in order to map the different types of olive groves and examine the correlation between topography and the distribution of olive cultivation. For this study, we focused on the site of Bni Quolla (covering an area of 192 km²) as a pilot site to validate the method prior to its application at the scale of the Ouezzane province
Impacts sur la santé publique de la dynamique des populations de renards

Avis et rapport de l'Agence nationale de sécurité sanitaire de l'alimentation, de l'environnement et du travail relatif à l'évaluation des impacts sur la santé publique de la dynamique des populations de renards (Saisine 2022-SA-0049). Maisons-Alfort: ANSES, 200 p.International audienceThe Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents. In this context, ANSES was asked to: (1) list the zoonoses present in France for which foxes play an epidemiological role, (2) identify other public health impacts associated with changes in fox populations, (3) explain the relative importance of the effects of changes in fox populations for humans and/or the environment, (4) analyse the feasibility of a cost‐benefit analysis (CBA) of the prevention and impacts associated with these zoonoses. In France, the fox is a source of zoonotic pathogens, with a major role for Echinococcus multilocularis, a parasite for which the fox is the main source of environmental contamination. However, reducing fox populations does not reduce the risk of transmission of E. multilocularis to humans or domestic animals, and may even have the opposite effect to the one intended. The main levers for action are those relating to exposure to environmental contamination. The fox is part of complex trophic networks, in which its specific role in regulating prey populations is impossible to determine because (i) several predators share the same prey, with a variable role for the fox among the predators, (ii) the dynamics of prey populations is also conditioned by factors other than predation. The relationship between the abundance of rodents and the risk of disease for humans has not been demonstrated either, due to the complexity of the trophic and epidemiological networks, their highly probable variability from one ecosystem to another, and the multiplicity of hosts. As a result, the data currently available does not allow any conclusions to be drawn about the epidemiological role of the fox as a predator of rodents hosting zoonotic agents. Finally, there is no public health justification for culling foxes, particularly for ESOD classification, except in the very specific and localised context of the fight against bovine tuberculosis, for which the selective culling of foxes in and around the livestock buildings of a domestic outbreak has been proposed. In addition, the expertise concluded to the feasibility of a CBA targeted at assessing the burden of alveolar echinococcosis and measures to prevent its transmission. The feasibility study shows the partial nature of a CBA targeting zoonoses, without taking into account other roles played by the fox in the ecosystem
