Global Warming Affects The Food Supply

There’s little doubt that food producers, large or small, are vital to our life.
Farming has typically been a difficult profession. Agriculture at best is quite susceptible to seasonal changes, not to mention extremes such as drought, flooding, and major storms. So will Global Warming seriously affect the food growing?
On the surface it would seem that all food growers would benefit from an extended season and hotter weather. Plus, increased quantities of carbon dioxide in the air might also aid productivity.
Nevertheless, the problem of Global Warming is that the excessive heat and temperatures will create wide variations in the climate. There could be massive precipitation in one place and extreme drought in another. This is way beyond what might be considered a normal range.
Impact on Food Supply
This change would require adaption that may prove too expensive for privately owned farms in North America, let alone farms that can barely get by in many underdeveloped countries. It is estimated that the result would be much greater hunger and famine in the world. What isn’t easy to tell is how these changes could affect the world’s economy.
To add to this, it’s yet unknown how certain plant diseases and insects may respond to these longer and warmer seasons. And don’t forget that weeds would prosper as well. Some expect this would lead to producers using even more dangerous herbicides and pesticides causing even further harm to the planet.
It is hoped that through advances in technology and ongoing research agricultural growers may be helped to be more adaptable. This would be important if crop selection and management have to change from year to year in response to weather changes.
Some items that are under study at present include:
- Government assistance in the farming infrastructure.
- Changes in crop variety or rotation.
- Shifting crop planting dates.
- Additional provision of irrigation water.
- Estimating how much stress water and land resources can support.
Food is essential to our way of life. Global Warming will put our food supply in danger. With so many persons in the world currently malnourished and starving the problem of Global Warming and its results takes on a vital urgency.
