This study focuses on the analysis of tourist offers and demand in the recreational sites of the commune of N’sele in Kinshasa. Indeed, tourism contributes to the development of cities led by specialist managers and/or enlightened, visionary, environmentalist leaders, endowed with irreproachable moral probity and informed on the environmental issues of the development of sustainable tourism. Furthermore, the commune of N’sele in the city of Kinshasa, although having the natural resources necessary for tourism, does not take advantage of it as it should, in terms of effective development of tourism. However, to conduct this study, a methodological approach was used with the use of the systemic approach, documentary analysis, observation, interviews, field surveys by questionnaire with semi-open questions. The sample of 490 tourists was drawn probabilistically within three categories of recreational sites. Manual and computer processing using software (Microsoft office 2016 and SPSS 22) allowed the processing, presentation, analysis of the results, followed by literary and scientific interpretations. It results from this study that the tourist offers and demand are weak, precarious, random or faltering in these recreational spaces studied. Only the sites of category A and some of type B have at least attractive offers but they are poorly frequented and the revenues do not really meet the understanding of the owners of the sites. Moreover, the comparison of these results with those of other cities or countries engaged in this sector, ours do not represent much. This is why it is imperative that Kinshasa sites opt for modern and sustainable developments, which remain an imperative, the application of managerial strategies, e-tourism, geomarketing, the organization of events, the green price, awareness of tourist culture, the valorization of staff so that these sites are more competitive, attractive and efficient.

Several factors threaten the integrity of aquatic ecosystem resources in the Democratic Republic of Congo. The banks of the Pool Malebo (Congo River) are also vulnerable to the presence of plastic pollution in its waters. This study aims to inventory the different types of microplastics in three compartments (water, sediment and fish) of the Congo River in the part of the Pool Malebo between the fishing stations of Maluku and Kinsuka in Kinshasa. The search for microplastics was carried out by trapping with the Manta net. The identification and classification of plastic debris recorded in the three compartments of the Congo River were done on the basis of the density of microplastics. The results obtained showed that the physical and chemical parameters of the waters of the Congo River in the Pool Malebo generally contribute to the disintegration of macroplastics into microplastics. All the digestive tracts of the sampled fish have microplastics and the consequences on the food chain are obvious especially tourists and other populations consuming these fish. From the point of view of relative abundance of waste, PELD with 35 debris or 79.5% are the most numerous than PP with 9 debris or 20.4%. Given the danger that microplastics represent for aquatic animals and human health, further research based on the characterization of plastic waste by more advanced techniques will provide additional information on the composition of microplastics present in the Malebo Pool.

Gastronomy concerns all travelers throughout their stays. Culturally speaking, across cities or countries considered as major recipients of international tourism, there are internationally recognized tourist culinary specialties and certified according to their authenticity, originality and preserved and conserved qualities. In addition, the Kinois often consume traditional tourist meals improved in different recreational sites scattered throughout this capital of more than 17 million inhabitants, especially in the tourist commune of the commune of N’sele. However, all these products are of agricultural origin, a significant quantity of which is imported or produced internally but under unknown conditions, often non-ecological. The overall objective of this study is the promotion of sustainable agriculture which is the basis of sustainable and perennial gastronomic tourism. The methodological approach used for this study is diverse and multidisciplinary. Documentary analysis, systemic approach, comparison, observation, field survey, probabilistic sampling of 490 tourists in different sites, computer processing of data (Word and Excel 2016), statistical approach and literary and scientific interpretation allowed the realization of this article. However, it results that Congolese gastronomy attracts 95% of tourists in these recreational sites located in the commune of N’sele and only 5% come for foreign meals. Of these dishes, freshwater fish occupy the first position, especially the form of cooking in papillote with freshwater fish leaves, called «liboke or maboke». Reason why, in the concern for health and tourism sustainability, the Congolese State must commit to the culinary certification of local meals, their promotion throughout the world, the financing and promotion of sustainable agriculture to support local agricultural products and sustainable culinary tourism. Tourists and investors in the sector must advocate for the preservation of our cultural and culinary identity through the consumption and promotion of our own meals.
