Developing a 21st Century View of Agriculture and the Environment
Bibliographic record
Abstract
Both poverty and malnutrition are serious problems in the world and both are interrelated. Food security for the poor depends on an adequate supply of food and/or the ability to purchase food. Unfortunately in the world today, more than 3.7 billion people are malnourished because of shortages of calories, protein, several vitamins, iron and iodine (World Health Organization, 2005; Rhodes, 2005). People can die because of shortage of any one of these nutrients or a combination of them. The total of 3.7 billion malnourished people is the largest number ever in history. In the world today, there are more than 6.5 billion humans (PRB, 2006). Based on current rates of increase, the world population is projected to double to more than 13 billion in about 58 years (PRB, 2006). At a time when the world population continues to expand at a rate of 1.2% per year, adding more than a quarter million people daily, providing adequate food becomes an increasingly difficult problem. Conceivably, the numbers of the malnourished will reach 5 billion in a few decades. Reports from the Food and Agriculture Organization of the United Nations and the US Department of Agriculture, as well as numerous other international organizations, further confirm the serious nature of the global food supply. For example, the per capita availability of world cereal grains, which make up 80% of the world's food supply, has been declining for more than two decades. This decline is taking place despite all the current agricultural and biotechnological facilities available. Malnourished people are more susceptible to numerous diseases, like malaria, tuberculosis, schistosomiasis and AIDS. The World Health Organization reports that there are more than 2.4 billion people infected with malaria, 2 billion infected with tuberculosis, 600 million infected with schistosomiasis and 40 million infected with AIDS (Pimentel et al. , 2004). In this chapter, we will examine the need to increase and make more rational food production, to conserve natural resources, to reduce food (crop) losses to pests, to consider the possibility and benefits of converting annual grains into perennial grains and to consider new crops and innovative minilivestock.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
