The whole cycle is interconnected. Another 36 percent is used for animal feed. Another 36 percent is used for animal feed. Pollination by other insect pollinators contributed to nearly $10 billion of crops in 2010. And animal feed is also an inefficient way of feeding people — about one-tenth as efficient, on a calorie basis, as eating crops directly.A devastating indictment of the Republican Party from a GOP insiderIn "It Was All a Lie," one of the GOP’s campaign operatives turns on the party he once helped build.The legal questions surrounding Trump’s new executive orders, answeredTrump’s actions appear largely legal. Again, as the numbers suggest, just 55 percent of crop calories go directly toward people. Chocolate, for example, is derived from cacao tree seed (annual world cocoa bean crop value, US$5.7 billion). "Pollinators are important contributors to world food production and nutritional security," said Vera Lucia Imperatriz-Fonseca, Ph.D., co-chair of the assessment and Senior Professor at the University of São Paulo. And the remaining 9 percent goes toward biofuels and other industrial uses.The proportions are even more striking in the United States, where just 27 percent of crop calories are consumed directly — wheat, say, or fruits and vegetables grown in California. Here’s what you need to know. The former reduces the availability of weeds, which supply food for pollinators. Did you know that pollinators in agriculture are responsible for pollinating approximately 30 percent of the world’s food and fiber crops? More than three-quarters of the world's food crops rely at least in part on pollination by insects and other animals. So the traditional strategy of "find new farmland to grow more food" is getting even harder.Humans can't eat biofuels, obviously. In the United States pollination by honey bees directly or indirectly (e.g., pollination required to produce seeds for the crop) contributed to over $19 billion of crops in 2010. Additionally, they improve quality of life, globally significant heritage sites and practices, symbols of identify, aesthetically significant landscapes. And a lot of food still gets wasted, either by consumers or due to poor storage infrastructure. Most plants require the assistance of pollinators to produce seeds and fruit. ... What percentage of the total energy in a food chain is passed from one organism to the next? Pollinators are necessary for three-quarters of our major food crops Not every species of plant requires animal-mediated pollination services. Sustainable development, including improving food security for the world's population, necessitates an approach that embraces the environment." Hence, enhancing pollinator services is important for achieving the Sustainable Development Goals, as well as for helping family farmers' adaptation to climate change. "Wild pollinators in certain regions, especially bees and butterflies, are being threatened by a variety of factors," said IPBES Vice-Chair, Sir Robert Watson. For example, wheat is wind-pollinated. The IPBES assessment has critically evaluated an enormous body of knowledge on pollinators, pollination and food production to ensure decision makers have access to the highest quality information. Many countries still don't farm as efficiently as they could due to insufficient fertilizer use. In addition to food crops, pollinators contribute to crops that provide biofuels (e.g. Improving pollinator density and diversity has a direct positive impact on crop yields, consequently promoting food and nutrition security. A pioneering study conducted in farm fields showed that one neonicotinoid insecticide had a negative effect on wild bees, but the effect on managed honeybees was less clear. 10%. But even if the rapid rate of improvement in crop yields over the 20th century continued, that still wouldn't produce enough food for everyone.Another possibility, as the map above shows, is that the world could devote more existing farmland back to feeding people. The assessment cites approximately 3,000 scientific papers and includes information about practices based on indigenous and local knowledge from more than 60 locations around the world.The assessment underwent two rounds of peer review involving experts and governments. When a seed forms in flowering plants, a fruit is able to grow to protect the seed. The rest goes toward biofuels or animal feed. 35%. Animals are more mobile than plants. For example, while there are only about 1,000 vertebrate pollinator species, it’s estimated that there are at least 16,000 different species of bees world-wide [3]. ""The complex and integrated development challenges we face today demand that decision-making be based on sound science and takes into account indigenous and local knowledge. Farmers could increase agricultural productivity by boosting crop yields — either through new farming techniques or through improved crop genetics. These practices include traditional farming systems; maintenance of diverse landscapes and gardens; kinship relationships that protect specific pollinators; and cultures and languages that are connected to pollinators.
Cecidomyiid and ceratopogonid midges are essential for its pollination.The volume of agricultural production dependent on animal pollination has increased by 300 per cent during the past 50 years, but pollinator-dependent crops show lower growth and stability in yield than crops that do not depend on pollinators.Nearly 90 per cent of all wild flowering plants depend at least to some extent on animal pollination. It is also the first assessment of its kind that is based on the available knowledge from science and indigenous and local knowledge systems. In August 2014, one of Foley's colleagues, Paul West, How much of the world's cropland is actually used to grow food?Feeding 9 billion people won't be easy: that's basically like adding two new Indias to the world in the next few decades.

By contrast, more than 67 percent of crops — particularly all the soy grown in the Midwest — goes to animal feed. Pollinated crops include those that provide fruit, vegetables, seeds, nuts and oils.
