The United Nations Food and Agriculture Organisation (FAO) hopes the high-level conference on world food security to be held in Rome from June 3 to 5 could also mark the re-launching the fight against hunger and poverty.
Also one could see initiatives announced to boost agricultural production in developing countries, it believes.
In a policy document prepared for the summit, it said the international community should take urgent, concrete actions to address the issues of hunger and malnutrition in the face of soaring food prices, scarce land and water resources, climate change, increased energy needs and population growth.
It said many agricultural commodity markets continued to be tight despite production increases and low stock levels were not likely to be replenished quickly.
It said the possibility of further sharp price hikes and continued volatility as a result of unforeseen events would remain there for a few seasons.
It said many countries were facing the dual challenge of sharp increases in food and fuel prices threatening macro-economic stability and overall growth.
Poor food buyers in the cities and non-food producers in rural areas who spent a large share of their income on food were the most adversely affected, it said.
The report lists 22 countries that are particularly vulnerable due to a combination of high levels of chronic hunger (more than 30 percent undernourishment) and being net importers of both food and fuel. Countries such as Eritrea, Niger, Comoros, Haiti and Liberia are particularly affected.
