SDG2:

❖ Healthy soils are the cornerstone in increasing agricultural output and attaining food security.

❖ Sustainable soil management such as crop rotation, organic farming, conservative tillage, etc enhance soil fertility and productivity, boosting global food production, lowering hunger, and enhancing long-term food security

SDG12:

❖ Sustainable management and efficient use of soil resources to ensure long-term productivity.

❖ By sustainably maintaining soil health, farmers may reduce the need for chemical inputs, minimize waste, and

manage the environmental impacts of agriculture, leading to a more sustainable food production system.

❖ Organic farming, crop rotation, conservative tillage, nano-fertilizer, biofertilizer, and integration of advanced technology in sustainable soil management.

SDG13:

❖ Soils serve as a natural carbon sink by storing organic carbon and sustainable soil management may enhance their ability to sequester carbon, mitigating climate change.

❖ Organic matter management and reduction of soil disturbance such as cover cropping, green manures, agroforestry, conservative tillage and no-till farming improve soil capacity to sequester/ store carbon.

SDG15:

❖ Sustainable soil management contributes to the reduction of desertification, promotes biodiversity and restoring degraded lands.

❖ Addition of organic amendments, reduce chemical inputs, crop rotation and soil erosion control help to maintain soil structure, moisture, and fertility which restore degraded soils and promote resilience towards soil degradation.

Class Activity Week 5: “Spot the Degradation”

Group Activity, real-world scenario, brainstorming

Learning Objective: To activate students’ prior knowledge and awareness of soil degradation by identifying visible signs, causes, and possible management practices from real-life contexts.

Instruction:

1. Watch this short video and pay attention to the different types of degradation (physical, chemical, and biological).

2. Find a real scenario online for one photo or short news post showing soil degradation in Malaysia or globally, and provide your reflection (2-3 sentences):

Location & when it is happening

What type of degradation do you think it represents?

What might be the main cause?

Suggest one sustainable management strategy that could reduce or reverse it.

3. ⁠The group representative will upload the picture & reflection via the PADLET comment section:

Group name

Picture of a real scenario of soil degradation

Reflections

4. ⁠The attendance will be based on the completion of the given task. The task should be completed before 5 PM today.

Each group should select different types of soil degradation:

1. Soil erosion

2. ⁠Soil compaction

3. ⁠Soil sealing

4. ⁠Soil urbanization

5. ⁠Soil acidification

6. ⁠Soil salinization

7. ⁠Soil pollution

8. ⁠Soil loss in organic matter

9. ⁠Soil loss of biodiversity

# data[].attributes.body
The theme focuses on the role of soils in cities and the challenges posed by soil sealing and urbanization. Urban soils provide essential ecosystem services, supporting food production, filtering water, storing carbon, regulating temperatures, and sustaining biodiversity. World Soil Day 2025 is a call to action. It invites policymakers, scientists, city leaders, civil society, and citizens everywhere to reimagine urban spaces through their soils, ensuring that people and nature can coexist in healthy, green cities.

# data[].attributes.body

2. Find one (1) previous related research study (2018 - current) of your chosen carbon sequestration strategy that shows impacts on soil carbon. You do not need to read the full paper; only focus on the key findings of soil carbon sequestration influenced by the strategy.

3. Prepare an infographic poster containing the following items:

Carbon sequestration strategy chosen

Explain HOW the strategy increases carbon storage (Mechanism of sequestration)

State whether the chosen strategy is SHORT-TERM or LONG-TERM carbon storage and explain WHY

Screenshot of the Research paper front page containing the title & author

From the research paper: Find out their FINDING ON SOIL CARBON, and why the findings matter to carbon sequestration.

4. Make sure to include all group members' names on the poster.

5. Upload the poster to the comment section.

6. The attendance will be based on the completion and submission of the infographic poster.
