Why Soil Matters
Our Changing Climate・2 minutes read
Soil degradation is a pressing issue, amplified by industrial agriculture practices that erode topsoil at a rate 17 times faster than natural replenishment, impacting plant health and global food security, highlighting the urgency to revise agricultural methods for sustainable soil management.
Insights
- **Human Impact:** Soil degradation due to industrial agriculture is accelerated, with the rate of topsoil loss far exceeding the natural replenishment process, highlighting the detrimental impact of human actions on soil health and sustainability.
- **Global Concern:** Nearly one-third of the world's soil is significantly degraded, underscoring the urgency for a shift in agricultural practices to protect soil fertility, promote biodiversity, and ensure sustainable food production in the face of climate change.

Recent questions
How does industrial agriculture impact soil health?
Industrial agriculture practices such as intensive cultivation and mono cropping contribute to soil degradation by depleting topsoil, necessitating the use of fertilizers that alter soil composition and affect essential organisms and fertility. This degradation affects plant health and makes it challenging to grow nutrient-dense food, highlighting the importance of reevaluating agricultural methods to protect soil health and combat climate change.
What is the average time needed to build an inch of topsoil naturally?
On average, it takes around 500 years for nature to naturally build an inch of topsoil. However, human activities, particularly industrial agriculture, are causing soil degradation at a rate 17 times faster than the natural replenishment process, emphasizing the urgent need to address this issue to preserve soil health.
How much of the world's soil is considered moderately or highly degraded?
Nearly 33% of the world's soil is classified as moderately or highly degraded, primarily due to human activities like industrial agriculture. This degradation impacts plant health and the ability to grow nutrient-dense food, underscoring the necessity of rethinking agricultural practices to protect soil fertility and combat climate change.
What are the consequences of degraded topsoil on plant health?
Degraded topsoil resulting from industrial agricultural practices affects plant health by making it more difficult to grow nutrient-dense food. This degradation alters soil composition, necessitating the use of fertilizers that impact essential organisms and fertility, highlighting the importance of preserving soil health to ensure sustainable agriculture and food production.
Why is it crucial to reconsider agricultural approaches to preserve soil health?
It is essential to reevaluate agricultural methods to preserve soil health due to the significant impact of soil degradation on plant health and food production. With almost one-third of the world's soil moderately or highly degraded, there is an urgent need to adopt sustainable practices that protect soil fertility, mitigate climate change, and ensure the long-term viability of agriculture.

Soil degradation: a critical issue in agriculture
- Soil degradation is a critical issue, with an average of 500 years needed to naturally build an inch of topsoil, lost at 17 times that rate due to human actions, particularly industrial agriculture.
- Industrial agricultural practices like intensive cultivation and mono cropping lead to soil degradation by decimating topsoil, requiring nutrient-filled fertilizers that alter soil composition, impacting essential organisms and fertility.
- Degraded topsoil affects plant health, making it harder to grow nutrient-dense food, with almost 33% of the world's soil moderately or highly degraded, emphasizing the need to reconsider agricultural approaches to preserve soil health and mitigate climate change.
