What are the causes of CO2 emission?
There are many sources of CO2 emission. We, as humans, exhale on average one-kilogram CO2. Plants and animals also ‘exhale’ CO2, which ends up in the atmosphere. In addition, vulcanic eruptions and defrosting of permafrost (permanently frozen soil) contribute to the emission of CO2. However, the vast majority of the CO2 emission is due to human activities. We drive our car, heat our houses when it is cold outside and use energy to cook our meals. This all costs a lot of energy. To obtain this energy we burn fossil fuels, increasing the amount of CO2 emission into the atmosphere.
What are the consequences of this CO2 emission?
The accumulation of CO2 emission has largely contributed to global warming. Greenhouse gasses in the atmosphere, such as CO2, prevent the heat from the earth to escape properly causing the warming of the earth, a process better known as the greenhouse effect. Global warming has several consequences. Heat waves occur more often, rainfall is more intense, and the sea level is rising. Especially in vulnerable areas, such as sub-Saharan Africa, people are confronted with the consequences of climate change on a daily basis. Extreme heat causes drying of the land, resulting in crop failure. When rain arrives, it is often very intense. Because a lot water is coming down at once, the water has no time to infiltrate into the soil, causing runoff of the water. Next to lower water availability within the soil, this causes erosion of the fertile top layer of the soil and downstream floodings. The lower water contents and decrease in fertile soil makes it hard to grow crops, causing a food shortage for the local communities. This can ultimately lead to famine. Because agriculture is often their biggest source of income, it can also lead to poverty.
What can we do about this?
Regreening helps! Recent studies show that nature-based solutions can contribute up to 37% of the CO2 emission intake required to keep global warming below 2 degrees Celsius. Vegetation cause the sequestration of CO2, decreasing the amount CO2 in the atmosphere and subsequently reducing the greenhouse effect, ultimately leading to the mitigation of global warming. Vegetation also causes cooling of the soil, decreasing the evaporation of water from the soil leading to increased water availability for plants, animals and humans. In addition, greening stimulates the water cycle, causing increased rainfall and the retention of water in the soil. This increasement of the soil moisture content makes the land available for agriculture again, producing food and income for the local communities.
Who is Justdiggit?
Justdiggit is a Dutch foundation with the goal to restore degraded ecosystems by developing, initiating and co-funding large-scale landscape restoration programs within Africa. Our regreening projects help to restore the water balance in the soil and bring back vegetation, which has a positive effect on the local and regional climate, increases water and food security and promotes biodiversity within the project areas. Within our projects we work together with local partners and communities. The communities involved directly benefit from our programs as we create a better living environment and increase economic development.Our unique approach is a media and communication-based strategy, involving all available communication and media on a local, regional, national and international level. With these sponsored media campaigns, we aim to amplify the eﬀect of landscape restoration programs, thereby creating a landscape restoration movement, promoting regreening throughout Africa.
