The paper discusses the problems facing countries when managing stocks of fish that move between their EEZs and the EEZs of adjacent countries, or onto the high seas. The action needed depends on the pattern of movement of the stocks. The different patterns of movement are discussed; they vary from small local dispersions in which only a small proportion of the stock cross boundaries between national EEZs to long migrations in which virtually all the stock may move from one EEZ to another.

Projections reveal that to sustain the likely world population in the year 2000, an increase of 60 percent in agricultural production will be required. "Is there sufficient land to meet these needs?" becomes the overriding question. However, little precise information exists on which to base a reliable answer. Previous appraisals of the global extents of arable lands, to support present and future human populations, vary from 3 to 7 thousand million hectares. Estimates of the populations these lands can support, vary from 7.5 to 40 thousand million.
