ABSTRACT

Landscapes located in the north-east of the DRC being composed of several species of flora and fauna are characterized by increasing human pressure, accentuated by cross-border and internal migration, with both positive and negative impacts on all development plans. The Epulu-Ituri-Aru-Garamba-Uelé landscape located in this area does not escape this generalized reality. Hence, the importance of understanding the factors that influence the spatio-temporal patterns of gender migration at the scale of this landscape, in order to identify both positive and negative impacts on the livelihoods of women and men local communities.

Generally, this study aims to contribute to the preservation and restoration of the ex-wetlands. Orientale province through the integration of gender, in the implementation of alternative measures that aim to ensure their conservation, in order to improve the well-being of the population. Specifically, it is a question of analyzing the spatio-temporal dynamics of the landscape related to the factors that influence the spatio-temporal patterns of migration between men and women; to identify the risks associated with the spatio-temporal dynamics of landscape-scale migration of men and women, with particular emphasis on socially vulnerable groups; identify and analyze the most effective and affordable local initiatives in risk management and propose an integrated wetland biodiversity management strategy. The stratified and systematic random sampling method was used for the collection of quantitative data; and group focus, individual interviews and group discussion were organized for qualitative data. Quantitative data was analyzed with SPP 3.1 software and R software; and content analysis was the main approach used to analyze the qualitative data, as well as the commented route method. The SWOT analysis was done to evaluate effective and affordable local initiatives; and the GIS tool was used to develop the migration mapping, based on the geographic coordinates taken with the Global Positioning System.

The results of our analyzes have shown that social, cultural, economic, ecological, political and security factors underlie the typology of migration, which is grouped into four main categories, including economic (or labor) migration, forced migration , the migration of constraint (or refugees) and climate migration. An analysis of many factors influencing the decision to migrate in this landscape shows that 40.98% of migrants seek stability, while 35.25% seek security for good development.

Water pollution (87.5%) resulting in the degradation of ecosystems (87.5%), poaching (75%) and illegal exploitation of natural resources (62.5%) are the main phenomena constituting the risks that are linked to migratory movements on the scale of this landscape. This also results in the encroachment of herds of herders in wetlands linked to protected areas (75%), deforestation (62.5%) and carbonization (12.5%) which are at the root of the destruction. forest, lake and fluvial ecosystems of the region. Mechanisms for large-scale interventions, including sensitization, water treatment techniques, securing and protecting biodiversity and endogenous knowledge, as well as participatory approaches are local initiatives that are considered affordable and effective. Integrated wetland biodiversity management has been identified as a sustainable strategy for restoring and maintaining degraded ecosystems by specific gender adaptation, with a view to enhancing the resilient development of communities.

Key words: Impact, Integrated Sustainable Management, Wetland, Climate Migration, Biodiversity and Conflict.
