Asa result, Chineseleadershavebeen especially afraid offood shortages, which hasled to a misguided food policy and caused great economic losses. The argument given by Mr. Lester R. Brown is misleading, and there isno food crisis in China. Food supply on the world markets is ample, and food prices have been declining over the past fifty years. For China, the cost of imported foodstuffs is less than one percent of its foreign exchange earnings. Maintaining a freefood marketismoreimportantthan having atotallyindependent domesticfood supply.展开更多
As El Nino effect continues to impact negatively on Africa＇s agricultural sector, great concern is rising about the damage to the continent＇s food security and what can be done to mitigate the fallout.

Ethnobotanical surveys were carried out in four ecological zones （I, II, III ＆ IV） involving a sample of 433 persons from 29 ethnic groups. Semi-structured interview, field observation, group discussions were used to collect data. Food shortage periods were defined using the agricultural calendar of main crops in three ecological zones （I, II, ＆ III）. One hundred and one EWFS belonging to 84 genera and 39 families were inventoried. The three main types of use of the EWFS were direct consumption, condiments and medicines. Twenty among the 101 EWFS recorded were highly consumed during food shortage periods with respectively 15 EWFS in ecological I, 14 in zone 1I and 12 in ecological zone III. All edible fruits consumed during food shortage periods were fresh fruits with abundant pulp. Six fruit species were sold to bring income to local households. These species were those which benefit from conservation measures through their husbandry in agroforestry systems.展开更多

However, the fluctuating food prices caused by oil price led to critics to biofuels. The paper surveyed biofuels production and grain production and consumption demand, and come to the conclusion that there was a little impact of corn ethanol on international food price, and there was no impact on China’s food prices. China has launched non-food biofuels development strategy to use marginal lands for growing hard crops, such as sweet sorghum, tuber crops, and switchgrass etc. to produce biofuels without any impact on food security in the future.展开更多
