- Registry title: L'Observatoire: At Least Four Dead and Over 3,200 Families Affected by Flooding
- Editorial note: News report from Journal l'Observatoire drawing on Civil Protection updates, with emphasis on flooded housing, road disruptions and response challenges.
- Original: [Open source]()
L'Observatoire reports at least four deaths and more than 3,200 affected families, with 1,285 homes flooded in Grand'Anse, South and West and 21 communes affected.
According to the report, 21 communes are affected across Nippes, Grand'Anse, South, North-West and West, with flooding, river overflows and infrastructure damage. In Baradères, the town centre is under water; floods were also reported at the Corail community centre and the Fond-Icaques school.
In the South, the collapse of the Ravine du Sud dyke is increasing risks for riverside populations. A landslide temporarily cut National Route 7 in Grand'Anse before Ministry of Public Works intervention, while the Jérémie–Chambellan road remained impassable at Laferme because a ravine overflowed.
Civil Protection highlighted several challenges: saturated soils, vulnerable precarious housing, and insufficient logistical resources in some departments. Clearing operations were continuing in Nippes.
#### Takeaways
- L'Observatoire reports 1,285 homes flooded across Grand'Anse, South and West, with West recording the largest number of destroyed houses.
- National Route 7 was temporarily blocked by a landslide; the Jérémie–Chambellan road remained impassable at Laferme.
- Civil Protection cited saturated soils, precarious housing and limited logistical resources as ongoing constraints.

The dissertation examines perceived vulnerability, local climate perception, climate awareness and preparedness across Grand'Anse, Nippes, Ouest, Sud and Sud-Est.
The study focused on coastal communities across five administrative departments of Haiti: Grand-Anse, Nippes, Ouest, Sud and Sud-Est. A cross-sectional household survey was conducted with 449 adult respondents.
It analyzed demographic factors, occupation in climate-sensitive livelihoods such as farming and fishing, climate change awareness, disaster experience, fatalism, self-efficacy, locality type and administrative department, using descriptive statistics, bivariate tests, and linear and logistic regression.
The findings show that perceived vulnerability, local climate perception, climate awareness and preparedness action are related but distinct dimensions of climate response. Disaster experience was the strongest predictor of perceived vulnerability to climate change.
#### Takeaways
- Disaster experience was the strongest predictor of perceived vulnerability to climate change.
- Perceived vulnerability, climate perception, awareness and preparedness are distinct dimensions rather than a single response.
- The survey covered 449 adults across Grand-Anse, Nippes, Ouest, Sud and Sud-Est.

- Editorial note: Official GEF project description of an ecosystem-based intervention to restore ecosystems and strengthen resilience in Haiti's Grand Sud.
- Original: [Open source]()
The intervention targeted protected and vulnerable landscapes in the southwestern peninsula, where weak enforcement left coastal communities exposed to hurricanes, floods, droughts and erosion, and environmental degradation undermined food security and disaster preparedness.
Haiti's southwestern peninsula hosts mangroves, marine habitats and fragile upland ecosystems that buffer extreme weather, but they face pressure from deforestation, overfishing and rapid unplanned infrastructure development. Protected areas were legally declared, yet enforcement capacity and climate risk management remained weak, especially at decentralized levels.
The intervention focused on the Grand Sud's protected and vulnerable landscapes, where environmental degradation undermined food security and disaster preparedness. An ecosystem-based approach included protecting mangroves and shorelines, improving land use and diversifying livelihoods, with enforcement strengthened through trained environmental agents.
A decree established a 5,835 hectare marine management area spanning Jérémie–Bonbon–Les Abricots. Women bore disproportionate burdens and faced high levels of violence, with limited access to safer, resilient livelihoods.
#### Takeaways
- The project promotes an ecosystem-based approach: protecting mangroves and shorelines, improving land use and diversifying livelihoods.
- A 5,835 hectare marine management area was decreed spanning Jérémie, Bonbon and Les Abricots.
- Environmental degradation undermined food security and disaster preparedness; weak enforcement left coastal communities exposed to hurricanes, floods, droughts and erosion.

- Editorial note: UN OCHA country page; its figures cover national humanitarian needs, deportations and the response plan, and it links to the flood response overview rather than giving flood casualty or damage counts.
- Original: [Open source]()
The page outlines national needs: 10 per cent of inpatient health facilities fully operational, 11 per cent in Port-au-Prince, and more than 225,000 people deported back to Haiti since the beginning of the year, 98 per cent from the Dominican Republic.
The OCHA page sets out a national picture. It reports that only 10 per cent of health facilities with inpatient capacity remain fully operational across Haiti, and 11 per cent in the Port-au-Prince metropolitan area. Since the beginning of the year, more than 225,000 Haitians have been deported back to the country; 98 per cent of them came from the neighbouring Dominican Republic.
The Humanitarian Response Plan has a budget of US$880 million and seeks to assist 4.2 million people who rely on lifesaving humanitarian assistance. It prioritizes urgent interventions in Ouest, Centre, and Artibonite, where armed violence and migrant deportations drive severe humanitarian needs. The plan aims to reduce immediate risks, stabilize households affected by repeated shocks, and restore access to essential services.
In the more stable areas of the Grand Sud and the Grand Nord, which host large numbers of internally displaced people, the page says humanitarian partners will support local integration, ease pressure on host communities, and prevent social tensions, working closely with development entities. The page also carries an overview of the flood response in Haiti, with a link to the full humanitarian response on humanitarianaction.info.
#### Takeaways
- Nationally, only 10 per cent of inpatient health facilities remain fully operational; in Port-au-Prince the figure is 11 per cent.
- More than 225,000 Haitians have been deported back to Haiti since the beginning of the year, 98 per cent from the Dominican Republic.
- The US$880 million Haiti Humanitarian Response Plan targets 4.2 million people and prioritizes Ouest, Centre and Artibonite.
- OCHA's page treats the Grand Sud and Grand Nord as more stable areas hosting large numbers of internally displaced people, with planned local integration support.
