Food, Nutrition, And Health, Problems And Prospects, D. K. Salunkhe Nov 1974

Food, Nutrition, And Health, Problems And Prospects, D. K. Salunkhe

Faculty Honor Lectures

Food, nutrition, and health - and their complex interrelationships - are necessities of life. Basically, nutrition depends on food; health depends on nutrition. Everyone needs to have enough good quality food to sustain himself. Satisfying that need on a world basis must be of concern to each of us.

Although accurate data are lacking, it is estimated that more than two-thirds of today's world population is afflicted by hunger and/ or malnutrition. Almost 300 million children are suffering physical and, probably, mental damage because of insufficient food. This evidence points to one of two conclusions: we have either too many …


Poplars In The Prairie Provinces, G. A. Steneker Nov 1974

Poplars In The Prairie Provinces, G. A. Steneker

Aspen Bibliography

The story of poplars is an unusual tale - a rag to riches story. The poplar has gone from weed to popular resource, because today this abundant species is being regarded by many as a possible source of newsprint, tissue, plywood and even livestock feed. Poplars provide choice winter and summer food for white-tailed deer and grouse, and the first prairie homes were built with and heated by poplar logs. Often considered a weed, the poplars of the Prairies are now facing a brighter future.

Seed Reserves In Desert Soils, David W. Goodall, Suzanne J. Morgan May 1974

Seed Reserves In Desert Soils, David W. Goodall, Suzanne J. Morgan

Memorandum

Soil and litter samples were collected from the playa, playa fringe and bajada zones of the Jornada Validation Site. These samples were analyzed for their seed content, special attention being paid to spatial distribution. At the time of sampling, there was little litter on the soil surface, and the litter contained only a small proportion of the total seeds present.
