LES CAYES, Haiti — Food, water and building supplies began to reach remote corners of Haiti on Wednesday as tens of thousands of people slowly rebuilt their lives after a devastating Category 4 storm hit last week.

In the southern seaside community of Les Cayes, a U.N. truck delivered water to the Sous Roche neighborhood while residents including 49-year-old fisherman Justin Cambry stood in line. The delivery marked the first time the neighborhood had received any help since Hurricane Matthew hit on Oct. 4.

“Life is completely destroyed here,” Cambry said. “It will take 20 years to get it all back.”

Haitians helped each other regain some semblance of their pre-hurricane lives as they awaited the arrival of more aid.

A community group that formed in the southern coastal village of Les Anglais cleared tree limbs from streets and placed them into piles while others gathered scraps of wood to start rebuilding homes.

Meanwhile, more than a dozen people gathered inside a neighbor’s general store in the western coastal town of Anse-d’Hainault that was serving as a makeshift shelter. The store had a small generator that provided a little light and power to charge phones.

“We’re looking out for each other,” said Walna Gevere, who traveled to her hometown from the capital of Port-au-Prince to be with her family.

Those who survived the storm have faced great challenges, including going days without food. The prices of bottled water, bleach and other vital items have jumped by as much as 25 percent amid worsening shortages.

Elancie Moise, an agronomist and director for the Department of Agriculture in southern Haiti, said between 80 and 100 percent of crops have been lost across the southern peninsula.

“Crisis is not the word to describe it,” he said. “You need a stronger word. It is much worse. There is no food for people to eat.”

In addition, there have been reports of assaults on women gathered in shelters, said Yolette Etienne, director for the U.K.-based group ActionAid in Haiti.

She traveled to the department of Grand-Anse in Haiti’s southwest peninsula to assess the damage when she was told about the assaults.

“Fortunately, the women organized themselves to capture the men and call the police,” she said, adding that shelters are taking more preventive measures.

The United Nations has called for $120 million in aid, noting that about 750,000 people in southwest Haiti alone will need “life-saving assistance and protection” in the next three months. Overall, at least 1.4 million people need assistance, the U.N. said.
