Puerto Alto, Mapajo, JunÃn, and Villamontes in Distrito 1 of Cobija are low-lying informal riverside communities along the Acre River bordering Brazil, facing chronic exposure to seasonal flooding, landslides and extreme rainfall. Poor infrastructure,, and high socio-economic vulnerability heighten localised risks, while riverbank degradation and loss of riparian ecosystems reduce natural buffers against adverse climate impacts.
Highly exposed to climate, urban, and biodiversity risks. The low-income population is vulnerable to frequent riverine flooding, extreme rainfall, and landslides, due to poor storm drainage and inadequate flood management infrastructure. Urban expansion in protected biodiversity areas increases exposure to habitat loss. Degraded riparian buffer zones along the Acre River, coupled with deforestation and erosion along riverside areas, further compounds environmental risks. The lack of ecosystem services, such as water filtration and soil stabilization, leave residents in low-lying areas particularly exposed to climate impacts.
High socio-economic vulnerability is driven by overcrowding, limited access to basic services, and a high dependency ratio, with many residents being children and the elderly. These communities face high poverty rates, low education levels, and inadequate housing increase sensitivity to climate hazards. Limited awareness, financial constraints, and a high number of dependents hinder residents' ability to invest in resilience measures and respond effectively to climate events.
Highly sensitive to climate, urban, and biodiversity risks and stressors. These communities are highly vulnerable to increased temperatures and precipitation, which will raise river levels and intensify flooding. Flood risks extend beyond safety concerns, directly affecting livelihoods, trade, and food security, with flooding disrupting daily economic activities, employment, and access to resources. The instability of the terrain, exacerbated by poor drainage. ecosystems are increasingly sensitive to urban encroachment and environmental degradation, as the lack of natural protections exacerbates the impacts of climate stress on local biodiversity and ecosystems.
Urban expansion is encroaching on protected biodiversity areas, which are located within conservation zones along the riverbank. Encroachment, combined with degradation of riparian buffer zones, landslides, and erosion along riverside areas, exposes local ecosystems to further harm. Low abundance of biodiversity in the area and the lack of ecosystem services exacerbate the vulnerability of local biodiversity to urban and climate pressures.
Limited adaptive capacity to climate, urban and biodiversity vulnerabilities. The community is exposed to compounded climate-biodiversity risks, with flooding from the Acre River and the degradation of critical natural habitats that support local biodiversity. Precarious location of residential settlements, inadequate infrastructure, and weak institutional capacities for preparedness and emergency response further hinder the ability to cope with and recover from climate shocks. Poor drainage, lack of flood management infrastructure, environmental degradation, and the absence of resilience-building ecosystem services severely limit the community's capacity to adapt to increasing climate pressures
Infrastructure services are limited and often inadequate. Basic services such as water distribution and electricity are present, but storm drainage is severely deficient, leaving the area highly vulnerable during flood events. Lack of effective drainage and flood mitigation infrastructure makes these communities particularly susceptible to, especially flooding and landslides.
