[Termes IGN] vagueRésumé : (auteur) Many coastlines are naturally exposed to submersion and erosion hazards. In this work, a combined GIS and wave modeling method is used to identify areas exposed to coastal erosion. The main objective of this work is the qualitative identification of shoreline sectors where wave and swell energy are important. The selected study area is “Cap Rosa” located in the El Tarf coast in eastern Algeria. The obtained results show that the eastern part of the study area is the most affected by wave impact. This preliminary identification can be used in a detailed vulnerability assessment along the coast while integrating other factors (physical and socio-economic) beside the shoreline exposure.

[Vedettes matières IGN] Economie forestièreRésumé : (auteur) National Forest Funds (NFFs) represent an increasingly relevant funding source for the forest sector at the global level. With the increasing role of NFFs, their structures and operational procedures are becoming more complex and diversified. While many of these funds are State-driven and often support projects that include public goods with a focus on social and environmental benefits, some also support privately managed small-scale “for profit” businesses related to wood and non-wood forest-based value chains. This paper describes some the recent developments of NFFs and presents the results of a research effort that analyzed how NFFs’ funding targeting small-scale forest enterprises can contribute to the provision of forest ecosystem services. For this analysis, five case studies from Costa Rica, Guatemala, Luxembourg, Portugal, and Tanzania have been selected. In specific, the Forest Financing Fund (FONAFIFO), the FONABOSQUE, the Forest and Climate Change Fund (FCCF) of Luxembourg, the Floresta Atlantica Fund, and the Tanzania Forest Fund (TaFF) are reviewed. The research addressed several key research questions, including: How are NFFs operations conceived to support small-scale forest businesses? What type of funding windows are targeting small-scale enterprises? What are the current practices of NFFs supporting ES provision through small-scale forest businesses? How could NFFs further support small-scale enterprises while unleashing contributions to the provision of ES?

[Termes IGN] variation saisonnièreRésumé : (auteur) Sensitivity to pollution in Burullus Lake was estimated based on the proximity analysis. The category of sensitivity was based on six factors including: agricultural areas, industrial areas, drains, Elboughaz, urban areas and fish farms. A statistical model was developed to estimate trophic state index (TSI) based on laboratory measurements of water samples at two different periods of time (Mach 2020 and June 2020) (R2 = 0.96 and 0.94, respectively). The important factors that were considered at the first period were chlorophyll, phosphate PO4 and oxidizable organic matter OOM. In the second period, the considered factors were ammonia NH4, silicates SiO4, and dissolved oxygen (DO). The category of TSI varied from oligotrophic to hyper-eutrophic conditions in March 2020, whereas it varied from eutrophic to hyper-eutrophic in June 2020. The eutrophication condition was higher in June than in March. This may be attributed to the huge amount of wastewaters, their contaminant load and season. The compatibility between sensitivity model and the obtained results in March 2020 was about 54.5%, whereas it was about 27.3% in June 2020. This reveals that the lake is highly sensitive to pollution and therefore it needs to be monitored regularly.

[Termes IGN] système d'information géographiqueRésumé : (auteur) Fuzzy analytical hierarchy process (FAHP) was employed to map and rank flood hazard zones within the Northwest Benin Owena River Basin (NWBORB). Topographic wetness index, elevation, altitude above channel, slope, drainage density, convergence index, and runoff contributing to water accumulation/stagnation were processed to generate the flood hazard map of the basin. Values for the relative importance of each factor for flood occurrence were obtained using FAHP; these factors were super-imposed using weighted overlay. Sensitivity analysis of the weights was conducted to determine their influence on the overall analysis. The resultant flood hazard map was classified into five zones very high, high, moderate, low, and very low. Sensitivity analysis of the result showed that runoff and slope were the most sensitive factors in the analysis with values of 1.163 and 1.132, respectively. A comparison between flood hazard map and historical floods within the basin established the reliability of the methodology.
