More Rural Research Is Needed
1 Agricultural research funding is vital if the world is to feed itself better than it does now. Dr. Tony Fischer, crop scientist, said demand was growing at 2.5% per year, but with modern technologies and the development of new ones, the world should be able to stay ahead.
2 "The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition and poverty," be said.
3 Research is needed to solve food production, land degradation and environmental problems. Secure local food supplies led to economic growth which, in turn, slowed population growth. Dr. Fischer painted a picture of the world"s ability to feed itself in the first 25 years, when the world"s population is expected to rise from 5.8 to 8 billion people. He said that things will probably hold or improve but there"ll still be a lot of hungry people. The biggest concentration of poor and hungry people would be in sub-Saharan Africa and southern Asia in 2020, similar to the current pattern. If there is any change, a slight improvement will be seen in southern Asia, but not in sub-Saharan Africa. The major improvement will be in East Asia, South America and South-East Asia.
4 The developing world was investing about 0.5%, or $8 billion a year, of its agricultural gross domestic product (GDP) on research, and the developed world was spending 2.5% of its GDP. Dr. Fischer said more was needed from all countries.
5 He said crop research could produce technologies that spread across many countries, such as wheat production research having spin-offs for Mexico, China or India.
6 "Technologies still need to be refined for the local conditions but a lot of the strategic research can have global application, so that money can be used very efficiently," Dr. Fischer said.
7 Yields of rice, wheat and maize have grown impressively in the past 30 years, especially in developing countries. For example, maize production rose from 2-8 tonnes per hectare between 1950 and 1995. But technologies driving this growth, such as high-yield varieties, fertilisers, and irrigation, were becoming exhausted. "If you want to save the land for non-agricultural activities, for forests and wildlife, you"re going to have to increase yield," Dr. Fischer said.
