Grafting is necessary for fruit trees to get productive crops

Doane, a senior executive at Monsanto, cited a number of
statistics:
· A world population of more than 9 billion is on the
horizon, compared with today’s figure of 6.7 billion.
· Standards of living are rising in many developing
countries, a trend that continues to mean greater demand
for more and better quality food. As one example, annual
demand for corn is expected to be 1.6 billion metric tons by
2050, compared with the current level of some 800 million
metric tons.
· Only a comparatively small amount of additional land is
available for "responsible" cultivation to achieve higher
production.
Doane, a senior executive at Monsanto, cited a number of
statistics:
· Agriculture, already a large user of water,
faces increased competition from urban
areas for available supplies.
· U.S. agriculture accounts for about 19
percent of the nation’s consumption of fossil
fuels at a time when concerns are increasing
about the impact of those fuels on climate
change.
Doane, a senior executive at Monsanto, cited a number of
statistics:
· Helping corn, soybean and cotton farmers
attain yields by 2030 double those achieved
in 2000.
· Reducing the use of key resources by 1/3
per unit of output over the same period.
· Improving the lives of farmers by making
agriculture more productive.
