The Rural Voice, 1986-04, Page 11RESEARCH IN THE THIRD -WORLD by Michelle Timko "Agriculture is evolutionary, not revolutionary," stated Dr. Hulse, Vice -President of Research Programs for the International Development Research Centre (IDRC) when he addressed the Western Branch of the Ontario In- stitute of Agrologists in London as part of a 14 -city lecture tour. Change must occur slowly with research based on the environ- ment, social structures, and pre- sent products grown. "For these reasons," comments Dr. Hulse, "the family farm is central to all activity and attention should be given to getting the products of research into the farmer's hands." The IDRC provides funding for agricultural research in a variety of countries worldwide. "Enormous amounts of money are not spent on agricultural research throughout the world," Dr. Hulse informs. Only 3 per cent of the world's total research funds are spent on agriculture; 25 per cent is spent on armaments. World population is expected to reach 6.2 billion by the year 2000, increasing the population per arable hectare to 5 to 6 people in the developing world. This in- crease will be partly due to the destruction of arable land, "a point not widely considered." Every year 5 -million hectares of soil are destroyed, over half by in- dustrial spread, construction, and mining. "The Chinese are wonder- ful because they do not waste land," compliments Dr. Hulse. "Every inch is either terraced for rice, planted in other crops or pastured." Overall, there has been a slight increase in per capita food produc- tion in all continents except Africa, which is "attributed to the recent drought and present structural dif- ficulties." Research has helped contribute to this increase by providing help to small land owners. "We (IDRC) do not only work for the large farm." Small plots are grown by individual farmers who benefit by increased production for family consumption and for market sale. World production of rice, the staff of life in countries such as Bangladesh or China, has reached 450 -million tonnes annually. Dur- ing the 1960s the IR8 variety was introduced because of its short straw and higher yields. However, it was susceptible to many diseases and pests. More recently IR36, though slightly taller, has demonstrated tolerance to these diseases. Varieties of rice have been developed that mature in only 105 days, allowing farmers to harvest as many as three crops per year. This alone is probably the main reason for increased production. Besides improving varieties, planting techniques are researched. Direct seeding of rice with pre - germinated seed enables harvest 30 days earlier than planting with ungerminated seed. Over the last five years these ad- vances and others have increased rice production in China by 30 per cent. One experiment used to en- courage the small farmer to use production planning is the "rice garden." Part of the crop is planted every two weeks so that harvesting does not occur all at once. Not only does this distribute labour, it also decreases the degree of shortages and surpluses at specific times of the year. Dr. Hulse points out that one major problem in many areas is the dry season. "They need stocks for the dry season like we need stocks for the winter. The monsoon rains produce one crop. Excess water at this time captured behind dams, can provide irrigation for another crop during the dry season. IDRC bases research on the interaction between crops." Unaware of nutrition and balanced diets, multiple cropping of cereals and legumes has been a tradition for third -world farmers in many parts of the world for thousands of years. In Columbia, maize, beans, and squash are a common combination. Beans are supported by the stalks; the squash leaves shade the weeds. Intercropping has been in- troduced in Nepal with rice grown in wide furrows between ridges of corn. Advancements have been made with fababeans, chickpeas, and lentils, the diet staple of most people in Alleppo, Syria. The potato, a crop long forgotten, has increased by 70 per cent in the past ten years in the tropics. Old and new forage species are being com- bined and introduced to improve pasture in Peru for alpacas and cattle. "The essential of cropping systems research is that it begins, continues and ends with the family farm." Biotechnology is also beginning to play a role in international research. Many native African cat- tle are susceptible to insect -carried diseases, a major constraint to in- creasing production. By trans- planting embryos into cattle which have developed immunity to the in- fections, the calves born acquire the immunities of both the sur- rogate and the natural parent. Deforestation is a common pro- blem in the third -world since the majority of people depend on wood for cooking and heating. Tree species are introduced into rural communities to provide food, fuel, feed and fertilizer (leaf mulch). Plantings also protect against wind and water erosion. In China, the yield and quality of bamboo is being studied. Bamboo is capable of growing 25 meters/year, and can be used for everything from construction to basket weaving because of its strong, but flexible fibre. Dr. Hulse stressed the impor- tance of women to the family farm in Africa. "Seventy per cent of the farmers in Africa are women. The men work in the mines." Many women spend 10 hours of every day fetching water or wood, and grinding grain. "It is the poor rural people we want to help," comments Dr. Hulse. Much of the increase in cereal production in third world countries comes from small to medium scale farms. IDRC has no political restrictions. Dr. Hulse believes many developing countries can solve their own problems if they can on- ly get together to talk. IDRC brings plant breeders and scientists together to exchange knowledge and experience. Through an evolu- tionary process this information has to be incorporated into family farms to benefit the rural com- munities economically and social- ly. ❑ MT APRIL 1986 9 1
