At a time when food is becoming increasingly scarce in many parts of the world and food prices are skyrocketing, no industry is more important than agriculture. Humans have been farming for thousands of years, and yet agriculture has undergone more fundamental changes in the past 80 years than in the previous several centuries. In 1900, 30 million American farmers tilled the soil or tended livestock; today there are fewer than 4.5 million farmers who feed a population four times larger than it was at the beginning of the century. Fifty years ago, the planet could not have sustained a...

Agriculture is a key sector for the economy of many countries and it can be potentially exposed to deliberate attacks which can have dramatic economic consequences in the food, feed, and fibre sectors. Intentional introduction of certain microbes may have serious rebounds even on human health when food results contaminated after harvesting of crops and processing of raw materials. Programmes aimed at attacks against agriculture and the agro-food sector through bioweapons were conducted in the past and still in recent years this kind of threads are documented. Prevention and preparedness...
