The sustainability of reforestation initiatives depends on the involvement local communities, whose lack ownership compromises efforts to combat deforestation in Lubumbashi Charcoal Production Basin. This study assesses activities two village areas (Milando and Mwawa), based individual interviews (50 individuals/village area) floristic inventories carried out types habitats (reforested unexploited) for each area. hypotheses tested were following: (i) Reforested tree species selected collaboratively, ensuring an inclusive approach; (ii) ecological parameters—density per hectare, quadratic mean diameter, basal area, diversity—of reforested sites comparable those unexploited miombo due protection allowing natural recovery; (iii) ethnobotanical patterns reflect varying levels anthropogenic disturbance limited diversity used reforestation. Thus, gathered data habitat woody selection management practices, while assessed condition these terms density diversity. results show that both areas, was concertedly (22.00–44.00% citations). Woody chosen according needs communities (40–52%) availability seeds (18.00–44.00%). Furthermore, practices include planning/assessment meetings (26.00–38.00%) maintenance activities, such as firebreaks (38.00–46.00%) surveillance (24.00%). Additionally, are being increasingly neglected, jeopardizing efforts. However, density/ha, did not significant differences between habitats, particularly at Milando (p > 0.05). similarity is 55.56% 93.75% but remains low (40.00–47.62%). lists also (43.75–31.58%). Finally, a total 442 individuals recorded 630 ones, with Fabaceae dominating types. Despite some cited like Acacia polyacantha absent, Brachystegia spiciformis emerged most prevalent areas. present suggest sustainable continuous effective reconstitution forest cover. To reinforce it recommended decision-makers conduct awareness-raising campaigns establish payment environmental service mechanisms motivate communities.

Introduction Forests in the Zambezi ecoregion play a critical role sustaining biodiversity and livelihoods of over 100 million people across Southern Central Africa. However, these forests face growing threats from human activities. This study assessed forest-cover changes at national scale within 2000 to 2023. Methods A total 600 Landsat images acquired for years 2000, 2008, 2016, 2023 were used analyze forest cover change. Forest was classified using Random algorithm, integrated with Geographic Information Systems (GIS) landscape metrics assess patterns fragmentation ecological transformation. Result The results showed significant reduction area 2,328,377.5 km 2 1,817,513 , corresponding an annual deforestation rate 0.95%. decline associated substantial decrease largest patch index, signifying increased driven primarily by dissection suppression. At country level, rates above 1% identified Malawi (2.07%), Burundi (1.92%), Zimbabwe (1.57%), Tanzania (1.06%), while lower observed Zambia (0.93%), Mozambique (0.92%), Angola (0.83%), southeastern Democratic Republic Congo (0.72%). Despite widespread loss, some limited stability regeneration offer potential restoration. Discussion findings emphasize increasing human-induced pressures on highlight urgent need coordinated restoration initiatives African Development Community (SADC). Crucial steps include engaging local communities governance, promoting natural regeneration, implementing sustainable agriculture clean-energy policies conserve maintain ecosystem services.

Water scarcity in rural areas represents a structural challenge that undermines social well-being, public health, and ecological sustainability. This study analyzes the water supply system community of Las Ánimas, located municipality Tecoanapa, Guerrero (Mexico), with aim understanding dynamics access, use, community-based management resources. A participatory qualitative approach was employed, complemented by quantitative tools, including semi-structured interviews, fieldwork, workshops. The results reveal strong pressure on resources during dry season, contamination springs due to intensive agricultural practices, lack wastewater treatment infrastructure, organizational weaknesses within local committee. Nevertheless, identified key elements autonomous governance, such as rules, monitoring, shared responsibility resource. concludes strengthening governance—together territorially focused policies, environmental restoration, education—is essential ensuring long-term sustainability systems highly vulnerable contexts.

Lualaba Province, located in the southeastern Democratic Republic of Congo (DRC), consists five territories with varied dominant land uses: agriculture (Dilolo, Kapanga, and Musumba west) mining (Mutshatsha Lubudi east). The province also includes protected areas significant governance challenges. tropical dry forests that cover unique Miombo woodland are threatened by deforestation, which poses risks to biodiversity local livelihoods depend on these for forestry. To quantify spatio-temporal dynamics Lualaba’s landscape, we utilized Landsat images from 1990 2024, supported a Random Forest Classifier. Landscape metrics were calculated at multiple hierarchical levels: province, territory, areas. A key contribution this work is its identification pronounced deforestation trends woodlands, where overall has declined dramatically 62.9% less than 25%. This coupled marked increase landscape fragmentation, isolation remaining patches, shift toward more heterogeneous use patterns, as evidenced Shannon diversity index. Unlike previous research, our study distinguishes between agricultural territories—which particularly vulnerable deforestation—and those areas, forest remains intact but still under threat. nuanced distinction types offers critical insights into differential impacts economic activities landscape. Our uncovers within underscoring failure current structures safeguard ecosystems. comprehensive analysis novel literature linking spatial patterns both pressures while simultaneously highlighting challenges exacerbate transformation. woodlands juncture, without urgent, coordinated intervention international stakeholders, ecological socio-economic foundations region will be irreversibly compromised.
