While agricultural industry has improved significantly since the Industrial Revolution, the pressure on food supply in the world is not without its challenges. It looks to me that this problem can be attributed to the ever-growing population relative to the underdevelopment in farming industry, and accordingly I will recommend some measure to tackle the problem.
One of the most frequently mentioned factors leading to the apprehension about food shortage is the accelerating population on the planet. The past century has witnessed an almost threefold increase in the world population to over 7 billion, which entails enormous demand for food supply. Unfortunately, the agricultural production has been left behind due to relentless urbanization worldwide, which acts as the major culprit that constantly encroaches on farmland the world over. To complicate matters even more, another concomitant consequence of city prosperity is the migration of younger generation from rural areas to cities, which exacerbates insufficient labor force needed by agriculture.
However, the aforementioned problems can be tackled with from both administrative and technological perspectives. Firstly, governments can legislate against further encroachment on agricultural land, thus preserving the land for farming purposes. Adding to the point is to apply new technology to increase crop production, whether these be farm machinery, organic fertilizers, or pesticides. Not to be left behind is the education at the importance of agriculture among youngsters, thus curbing the brain drain from village to cities.
I would conclude therefore, the imbalance between food demand and supply is caused by the population explosion and the trend towards urbanization; both issues can be properly addressed with the combination of legislation, technology and education.
