What is world agriculture and why is it important?

World agriculture has been able to meet the rapidly growing global demand for food, feed and fibre over the last half century at real agricultural prices that were falling for much of the time, at least until the mid-80s. This was only possible due to sizeable agricultural productivity growth.

How do we increase agricultural production in developing countries?

In developing countries, 80 percent of the necessary production increases would come from increases in yields and cropping intensity and only 20 percent from expansion of arable land.

How much more agriculture will be needed to meet global food demand?

The general consensus is that global agriculture production has to be increased by about 60-70 percent from the current levels to meet the increased food demand in 2050. This takes into account several factors. First, the changes in dietary habits.


How does agriculture help the world?

Pasture and cropland occupy around 50 percent of the Earth’s habitable land and provide habitat and food for a multitude of species. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality.

Can agriculture feed the world?

According to estimates compiled by the Food and Agriculture Organization (FAO), by 2050 we will need to produce 60 per cent more food to feed a world population of 9.3 billion. Doing that with a farming-as-usual approach would take too heavy a toll on our natural resources.

Why are robots good for farming?

One reason small, mobile robots could be good news for farming is that they can replace a lot of the work done by large conventional tractors. Ordinary tractors are heavy. When they roll across the field they compact the soil. That crushes the gaps inside, reducing the size of the pores that hold air and water. This compaction significantly affects the soil’s ability to hold onto water and so a crop’s ability to take that up, along with the nutrients.
