What are advantages of farming?
Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world’s working poor works in agriculture. Farming creates more jobs, beginning with farmers, and continuing with farm equipment makers, food processing plants, transportation, infrastructure and manufacturing.
What are three advantages of farming?
The Pros and Cons of Industrial Agriculture
- It increases food production.
- It lowers consumer costs.
- It encourages technological development and innovation.
- It creates employment opportunities.
- It lengthens food availability.
What are the objectives of farming?
Motivating farmers for diversification of areas from traditional crops to commercial crops. Monitoring soil health and testing of nutrient level of soil samples collected from farmers fields across the State. Educating farmers on soil and water conservation technologies through implementation of Watershed Projects.
How does farming destroy the environment?
Agricultural livestock are responsible for a large proportion of global greenhouse gas emissions, most notably methane. In addition, overgrazing is a major problem regarding environmental sustainability. Cattle and other large grazing animals can even damage soil by trampling on it.
What are the negative effects of agriculture on the environment?
Agriculture is the leading source of pollution in many countries. Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations.
What are some positive impacts of irrigation?
Drip irrigation
| Pros | Cons |
|---|---|
| Saves water by minimizing evaporation | Method cannot be used with high iron content water because emitters become clogged |
| Nutrient losses from leaching is reduced | Maintenance is required to keep system going |
| No land grading required | Chewing on tubing from insects and rodents can cause water leaks |
What are the effects of over irrigation and poor drainage?
Over-irrigation can cause deep drainage from rising water tables that can lead to problems of irrigation salinity requiring watertable control by some form of subsurface land drainage.
Is it possible to have irrigation without drainage?
Irrigation is often accompanied by drainage, which is the natural or artificial removal of surface and sub-surface water from a given area. Artificial drainage is always needed, except in cases with deep groundwater levels.
