The contribution of nutrients from animal pollinated world crops has not previously been evaluated as a biophysical measure for the value of pollination services. This study evaluates the nutritional composition of animal-pollinated world crops. We calculated pollinator dependent and independent proportions of different nutrients of world crops, employing FAO data for crop production, USDA ?id=/

Introduction. Crop pollination mediated by wild and domesticated animals is a crucial and endangered ecosystem service.Recently, the global economic value of pollination from domesticated and wild animals has been estimated at € billion, while the consumer surplus loss associated with a total loss of animal pollination service was estimated between € and € :// The most widely used and comprehensive data on food supply and consumption is published by the UN Food and Agriculture Organization (FAO).

Material and methods. We first estimated the proportion of crop production depending on animal pollination.

Predictions of a global food crisis — that the world’s food production would not be able to keep pace with population growth — have a long history. In the 18th century the English cleric Thomas Robert Malthus hypothesized that gains in per capita resources would inevitably be outstripped by population until food supplies finally acted as a barrier to further growth.1  population persistence, suggesting links between pollination, seed population and demographic viability in this species (Groom ).
