Have you ever heard of Andisols? They are a vitally important building block for ecosystems in the Americas including Andean forests and high-altitude wetlands known as páramos, not to mention the cultivation of food. In this post, I’ll explain more about these soils and why it’s crucial to protect them.
The Food and Agriculture Organization of the United Nations (FAO) defines Andisols as a type of volcanic black soil typically found in mountainous regions. Andisols occupy roughly 1% of the world’s land surface area, primarily in the Ring of Fire, a string of volcanoes and active tectonic hotspots along the edges of the Pacific Ocean. The ring runs through Chile, Ecuador, Mexico, Japan, Indonesia, New Zealand and other countries, with among the world’s greatest amount of Andisols found in Colombia.
Andisols are an essential tool for agriculture and can be used to cultivate sugarcane, tobacco, potatoes, tea, vegetables, wheat, rice and other crops. These soils also sustain fragile ecosystems in the Andes mountains from forests to páramos, helping to provide essential nutrients and regulate the water cycle. In short, Andisols play a vital role in Colombia’s natural landscape.
On the world stage, the protection of Andisols is equally important to sustain the food requirements of an increasing global population. By 2050 there will be some nine billion people, and, according to the FAO, to feed them we will need to produce “another one billion tons of cereals and 200 million tons of livestock products per year.” Right now, soil conservation, the protection of ecosystems and sustainable food production are merely transcendental topics for humanity. A rational and respectful use of soils is strategically important.
In 2050, a hungry person will not be able to eat banknotes, electronic devices, cars, gold bullion or gasoline. We will face a serious problem if no fertile soil is left for food cultivation. Already today millions of people that go hungry due to unequal food distribution. FAO data from 2011 shows that “almost one billion people are undernourished, particularly in Sub-Saharan Africa (239 million) and Asia (578 million).”
While Andisols play a critical role in food production and ecological health, the development of extractive industries – primarily energy and mining – are causing serious negative impacts on these rich soils in Colombia. Public policies must be put in place to regulate and guarantee environmentally sustainable management of these essential soils because the country’s food security and sovereignty depend on them, as does the conservation of mountain ecosystems.
To properly protect Andisols, we need to implement a legal framework to ensure they are used in a responsible and environmentally sustainable way for food production and that they are protected from harmful extractive industries. The FAO World Soil Charter of 1982 provides the following guidance to the world’s governments, including Colombia’s: “Develop a policy for wise land use according to land suitability for different types of utilization and the needs of the country.”
Regardless of any directives from the United Nations or whatever other international organization, Colombia’s future rests in our own hands. We need to think about how we can guarantee our viability, survival and, of course, our food. We must also consider how to fulfill our responsibility of caring for a country with an incredible wealth of biopersity, from flora and fauna to water supplies and Andisols.
