Ban Ki-moon, the UN secretary-general, is calling on the international community to "create a new Haiti" out of the wreckage left by January's devastating earthquake.

Representatives of more than 100 countries are due to gather for an international donors' conference at the United Nations on Wednesday, where they will shift the focus from humanitarian efforts to long-term recovery and developmental goals.

One of the key objectives is to reform and rejuvenate Haiti's agricultural system to allow farmers to increase food production and cut imports of rice, sugar and poultry.

However, in Haiti's agricultural bread basket, some farmers are worried that they will not get the help they need to expand food production and feed their country.
