DAKAR (Reuters) - Senegal's gross domestic product (GDP) is forecast to grow at 5.4 percent next year and the figure would be 0.2 percentage points higher but for a regional outbreak of Ebola, the head of the country's economic forecasting office said on Thursday. GDP growth in 2014 is expected to be 4.5 percent, up from 3.5 percent the previous year, while inflation is projected to climb to 1.4 percent in 2015 from 0.8 percent this year. "We expect an economic growth rate of 5.4 percent in 2015 thanks to public investments in the energy, agriculture, tourism and infrastructure sectors," Serigne Moustapha Sene, head of the forecast and economic studies office, told reporters. Senegal, one of West Africa's most stable democracies, exports peanuts, seafood and phosphates. President Macky Sall secured pledges worth about $7.8 billion at a donor conference in February to help kick-start a development plan aimed at diversifying the economy and doubling economic growth rates over the next decade. More than 5,000 people have died of Ebola in Guinea, Sierra Leone and Liberia. Senegal has had just one imported case and the disease's impact on GDP this year has been minimal, but fear of the disease can affect tourist numbers.
