Process analysis in the coastal zone of Bénin through remote sensing and socio-economic surveys

Intensive erosion has affected the coastal zone of Cotonou for several decades. An analysis of satellite images showed an average coastline retreat of 115 m in the study area over the period 2002-2013 with several hundred houses destroyed. Since 2014, a stabilisation of the coastline is observed. This study aimed at identifying the atrisk population and at analysing the perceptions of people who experience and those who manage coastal erosion risk, as well as the responses adopted. Based on four criteria and their hierarchy, we identified five profiles of inhabitants in this risk zone. (1) Wealthy people who leave the zone when they are affected or (2) fall into the category of people in danger in case they cannot migrate. (3) Fishermen who deliberately stay near the sea. (4) The most precarious people, trapped in the risk zone. Finally, (5) poor newcomers who continually increase the at-risk population. With the recent stabilisation of the coastline, the national authorities manage the "hazard" component of the risk. However, the majority of the population is not serene. The anthropogenic stress linked to evictions gradually replaced the stress to be engulfed by the sea. We conclude that the "vulnerability" component of the risk is not yet resolved. All categories of the population in this sensitive area need to be secured. Cooperation among multiple levels of governance, the application of land use planning regulations and of the Kampala Convention and the involvement of local communities are all measures which will enable to meet this objective.

“…This area constitute the strict part of the coastal area which spans between 1° 44′ 30″ to 2°37'00 Eastern longitude from Togo in the West to Nigeria in the East and between 6° 15′ 50″ to 6°44'85''Northern Latitude. It takes into account 39 communes and covers an area of about 12,000 km 2 , corresponding to approximately 10.5 % of the country territory (Teka et al 2012). This study was conducted in the strict coastal zone that comprises the ve coastal communes which have access to the sea (Sèmè-Podji, Cotonou, Abomey-Calavi, Ouidah and Grand Popo).…”

In Benin, mangroves are an important resource for the coastal populations who use them for firewood, salt preparation but also for feeding ruminants in the surrounding meadows. However, the pressure exerted by exploitation on fodder in the mangroves has not been quantified. This study aims to understand the relationship between mangroves and ruminants in the coastal zone of Benin. Ethno-botanical data were collected from ninety (90) ruminant breeders in fifteen (15) villages close to mangroves along the coastal belt, using individual interviews and group discussions combined with a tourist guide and a semi-structured questionnaire. The herders provided, among other things, mangrove species used as food and for ruminant health. Cross-tabulations, with calculation of chi-square statistics, were used as well as means and standard deviation values of continuous variables calculated and compared between mangrove trends observed using the non-parametric Kruskal-Wallis test. Rhizophora racemosa , Avicennia africana , Paspalum vaginatum , Zanthoxylum zanthoxyloides and Blutaparon vermiculare were the species mentioned. Local communities are aware of the need to restore and ensure the sustainable conservation of mangrove ecosystems. The main restoration and conservation measures indicated by the pastoralists are the planting of mangroves, rational logging through the control of logging, no fires after logging. These measures vary according to ethnicity and depend significantly (p < 0.001) on the type of mangrove. However, these modes of exploitation of mangroves by livestock breeders have no effect on their dynamics. However, the involvement of farmers is dispensable for the conservation of mangroves.

“…Majority of our respondents agreed that illegal logging is a major factor in the extinction of mangrove forests (69.0%) and land use exchange activities (78.0%) such as aquaculture, agriculture, and hotel construction. It is undeniable that that mangrove ecosystems are facing a progressive degradation due to the abusive deforestation, the uncontrolled settlements and the occupations held at the coastal area [41]. These activities have caused the inevitable retreat of the mangrove forest cover and decrease the fishery output.…”

Mangrove forests degradation is happening globally at an alarming rate since the 80's. Land conversion for human activities is one of many reasons contributing to the issue. The access the Knowledge, Attitude and Practice (KAP) on the function and conservation of mangrove, data was collected in Kuala Langat, Selangor within the vicinity of Sijangkang Mangrove Recreational Park using in-depth interviews (N = 100) and analysed using using ANOVA and linear regression. Results revealed that the respondents understand the importance of mangrove forests with high total mean knowledge score (80.93±7.77), attitude (75.83±8.51), and average on practice (55.95±11.44). Education is an important indication; resident status will determine the attitude towards the knowledge on the mangrove conservation. The linear regression depicts positive correlation between KAP variables where any changes will affect other variables.
