Farming before the revolution was a common example of livelihood and a source of food. When Britain started to become more closely involved with the colonies, farming was more centered around producing a plethora of agriculture in order to gain a profit. After the revolution, farmers could focus on producing crops and agricultural products for themselves rather than focusing on the surplus of supplies needed to gain revenue. Tobacco was still an important export after the revolution as well as new agricultural products such as wheat and corn.
French Revolution
The lord was able to roam and destroy crops in the heat of a chase for hunting a rabbit for sport. The people were not allowed to kill the rabbits and that was a law passed by the king that had to be obeyed. As a result, the hard work farmers did was treated poorly by the elite who were ignorant of the Third Estate. During the revolution, it was difficult to farm because of the harsh weather and natural disasters. Agricultural produce was reduced to the point of hoarding and the fear of no profit. Because of the poor farming, food was hard to come by and the price of bread and other sources of food rose.
Mexican revolution
During the Mexican Revolution, many resources became limited to the people that would farm and have land. Trading became essential to anyone in the farming industry. Many people would farm and get the supplies that they had and trade with other people or let them buy it if it was needed. After the Mexican Revolution, land, as said, was determined by class and race. If you were more wealthy and in the upper class then you had more of an opportunity to get some of the best resources.
Zimbabwe
Originally, Zimbabwe had plenty of fertile land for crops, but social issues between races caused squatters to forcibly seize control of over 4000 white-owned farms. In the years that followed, unskilled farmers and major flooding caused the farms to be operated poorly and a massive country-wide food shortage to occur. Proper enforcement of the original Land Reform Programme will hopefully mean that farming practices will be done correctly again, which will hopefully reduce the problems of the food shortages. Whether or not this will continue to be enforced properly remains to be seen.
