Why is it important to practice farmland restoration?
What is farmland restoration?
The
Basics
Farmland restoration is the process of restoring land to a state it can be productive. Often, this is land that has succumbed to desertification.
What is desertification?
What is desertification?
Desertification is the degradation of land that has resulted in a loss of biodiversity. The land's soil has become depleted and is now dust and dirt.
The Problem
The
Problem
The main cause for farmland degredation is from topsoil erosion and agricultural practices depleting nutrients.
Economic Effects:
Economic Effects
Depleted soil makes the agricultural process nearly impossible. Farmers who used to generate income by selling crops are no longer able to, disrupting the economy of the entire area.
Social Effects:
Social Effects
Unable to generate enough income to support their families, local farmers are forced to move out of desertified areas. Other people residing in the area no longer have a food source, causing the entire land area to be abandoned.
Environmental Effects:
Environmental Effects
The desertified land experiences a loss of biodiversity. Plantlife struggles to grow, and as a result animals cannot easily survive in the area.
How can we fix this problem?
The
Solution
In order to feed our growing population and protect the world as a whole, it is vital that abandoned cropland and pastureland is restored to a state of long-term productivity.
Regenerative Agriculture
Regenerative Agriculture
Regenerative agriculture practices helps to rebuild soil organic matter and restore degraded soil biodiversity. It has the additional benefits of carbon drawdown and improving the water cycle.
Regenerative Agriculture Practices
How to Practice Regenerative Agriculture
- Plant cover crops (plants that are grown to improve soil health) and rotate crops between seasons to create ideal conditions for biodiversity
- Eliminate or decrease tillage to reduce erosion and the release of carbon dioxide into the atmosphere
- Reduce synthetic fertilizer usage to prevent chemicals from seeping into the environment
- Use conservation grazing methods to maintain the habitat
Planting Trees
Planting Trees
The planting of trees can help reduce soil erosion. Establishing a tree plantation will help keep the soil in place, and provide an area for crops to be planted with less risk of disturbance from wind and rain.
Looking into the future
The Economics
The
Economics
Scenario 1: 219.16 million hectares are adopted (32 percent of the total available land area).
With this scenario by 2050 the lifetime net profit of farm restoration would total $134.4 Billion and and net operation savings would total $2.34 Trillion
Per Acre
The average industrial farm produces about $474 /hectacre per year while farmland that has been restored produces about $530 /hectacre in revenue per year
The Impact
Final Outcome
About 1 billion acres of farmland have been abandoned due to land degradation. By 2050 424 million acres could be restored and converted to regenerative farming. With regenerative farming 9.5 billion tons of food can be produced and 14.1 gigatons of carbon dioxide can be removed from the atmosphere.
