The Tragedy of the Cerrado Deforestation

Were you aware? The heart of South American biomes is at risk.

The Cerrado is one of the oldest ecosystems in the world, a savanna far richer than its African counterpart. Just south of the Amazon rainforest, it once sprawled over an area half the size of Europe. It holds the springs to three of the major rivers in South America and holds the second largest freshwater reservoir in the world.

Its trees allow for the rainfall coming from the Amazon forest to be stored and slowly feed the water tables through deep-rooted trees forming an “inverted forest”. This, in turn, feeds watersheds that will flow back to the Amazon. Without trees, rainfall erodes and compacts the soil instead, evaporating fast, and preventing the regular rain cycle to happen. The only thing holding this cycle in place is the remaining Cerrado vegetation. Unfortunately, only a tenth of it is protected and currently is at only 20% of its original area.

The Cerrado deforestation has been 5 times faster than the Amazon for the last 15 years. A number of international articles in Nature magazine, The NY Times, The Washington Post, institutions such as the UN Food and Agriculture Organization, the WWF, Mighty Earth, Mongabay, and countless other respectable sources has been documenting this process, but it just keeps going.

Deforestation is already showing its ugly head in Midwestern Brazil. Currently, over a thousand cities face major water shortage issues. All of them related are to the Cerrado’s now erratic water cycle.

If the Cerrado collapses, the Amazon rainforest collapses in less than 30 years. If the Amazon collapses, the domino effect will put us in serious trouble regarding climate change.

3 Ways Baru Seeds Impact The World Positively

Did you know baru seeds are much more than a snack? These are ways baru seeds impact the world and are beneficial to everyone:

    1. Socially
      The foraging of baru seeds generates revenue to local communities and creates a sustainable industry in the Brazilian savanna. It is a poor region of a country with a huge wealth gap. Baru takes power away from large agribusiness trading corporations as it creates self-employed families and co-ops. This stimulates the local economy and also shares revenue a lot more evenly than the corporations.


      Baru seeds are individually handpicked and processed. This employs hundreds of communities and discourages deforestation as it generates income.

    2. The Amazon
      Baru seeds bring awareness to a little-known fact: the Cerrado’s deep connection to the Amazon rainforest’s water cycle. Baru trees, as other Cerrado deep-rooted species, allow rainfall to enter water tables, which eventually form major Amazon rainforest watersheds.  Thus, baru and other deep-rooted trees allow a massive water cycle to come full circle. Because this distributes humidity and avoids severe droughts, it hinders self-amplified deforestation actively in the Cerrado and passively in the Amazon rainforest.


      Water clouds come from the Atlantic Ocean (1) and enter the Amazon rainforest becoming flying rivers (2), heading south (3) towards Midwestern Brazil (4). This rainfall penetrates the soil through deep-rooted vegetation and integrates water tables that feed rivers such as the Tocantins, Araguaia, and Xingu (5), returning to the rainforest.

    3. Climate Change
      As published in several magazine articles, such as in Brazil: Urgent action on Cerrado extinctions: “(…)our findings show that a severe extinction episode is unfolding in the Cerrado, with plant extinctions projected to be an order of magnitude higher than all global recorded plant extinctions so far — yet in our view, this catastrophe can be avoided(..)”. Unlike the Amazon rainforest, there are very few laws protecting the mostly deforested Cerrado. There is also very little international awareness, and because of this, great vulnerability to the agribusiness lobbying. Several credible sources note the huge threat the collapse of the Cerrado could pose to the global environment and economy. Business-as-usual scenarios predict a collapse of the Cerrado, and by proxy the Amazon, by 2050. This is due to a feedback loop caused by the state of deforestation and consequent increasingly severe droughts. We are literally on the verge of living a Black Mirror episode.

A Biome Under Threat

“With over 4,800 plant and vertebrate species found nowhere else, the Cerrado is a global biodiversity hotspot. It also spans three of the largest watersheds in South America, contributing 43% of Brazil’s surface water outside the Amazon. Despite its enormous importance for species conservation and the provision of ecosystem services, the Cerrado has lost 88 Mha (46%) of its native vegetation cover, and as little as 19.8%
remains undisturbed. Between 2002 and 2011, deforestation rates in the Cerrado (1%
per year) were 2.5 times higher than in the Amazon.”
” […]The Cerrado’s beauty and ecological significance are profoundly underappreciated, even among urban populations living in the biome. The 55% decline in deforestation rates in the Amazon in the period 2010–2014 is nationally and internationally recognized. However, the increases in losses of native vegetation in the Cerrado of 41% during the same period went largely unnoticed. Indirect land use changes are difficult to establish, but a number of studies infer translocation of deforestation from the Amazon to the Cerrado.[…]”
Soybean harvesters on a massive soybean field“[…]The Cerrado has great social importance as well. Some 12.5 million people depend on its natural resources to survive and thrive. Traditional communities and small farmers are everywhere where the native vegetation remains, but suffer intense pressure from crop and cattle expansion. The Cerrado is inhabited by traditional peoples (indigenous, quilombolas, geraizeiros, sertanejos, vazanteiros) who over many generations have developed sustainable and mutually beneficial uses of the region’s biodiversity and natural resources. Satellite-based evidence shows that native vegetation is better protected when conservation units are managed by local and traditional communities than by government park guards, who have a limited capacity to control illegal logging, poaching, and mining. Rapid and extensive loss of native vegetation in the pristine regions causes an intense fragmentation, undermining important ecological functions. The vast territories dedicated to large-scale monoculture eliminate the ecological “corridors” that flora and fauna need to migrate and thus survive extinction.[…]”
Baru and other incredible species are increasingly under threat in the Cerrado, and with them, water reservoirs and local communities. Please raise awareness on this cause!

The Importance of the Cerrado – Part 1

Hey everyone! Today we’re going to talk about the importance of the Cerrado, and by extent, baru trees.

Some folks approach us during demos ignoring this huge savanna we have in Brazil, and sometimes even suspicious of baru trees! People presume baru is either a GMO, since nobody’s ever heard of it in North America, or its processing demands a lot of water, like almonds do. That’s perfectly fine since there is not a lot of material in English out there about it, but it’s time we shed some light on the important relation of baru, water and the Cerrado.

cerrado2Let’s start with the basics. The Cerrado is this massive South American biome, second only to the Amazon rainforest in size, and the most biodiverse savanna in the world. That’s right, more diverse than the African savanna. It originally spread for over 2 million square km, mainly in Brazil, with small parts in Bolivia and Paraguay – roughly half the size of Europe overall.

What we call “Cerrado” is actually a mesh of four different vegetations: forest savanna, wooded savanna, park savanna and gramineous-woody savanna. Baru trees and other deep-rooted wild species grow in all of these, which feed and harbor the fauna, protect the soil against erosion and allow for rain to enter the soil.

Thus the Cerrado is an important receiver, keeper, and disperser of water to very important watersheds in the continent, namely the Amazon, Prata and São Francisco Basins. It acts like a sponge through an “inverted forest” of deep roots. This allows the savanna to stay alive by slowly releasing water until the rain season comes back, as it gets extremely dry on the surface during the southern hemisphere winter.

You can see the extent of the Cerrado in Brazil (in brighter color) and its water on the map below:


The underground storage by the “inverted forest” feeds watersheds and important aquifers such as the Guarani, the second largest in the world, with a 1,200,000 km² territory. 

However, for the last 25 years, around 40% of the overall vegetation has been deforested for industrial crops, mainly soybeans. Another 40% were deforested by the cattle and charcoal industry.

deforestationcerradoOnly circa 20% of its original vegetation remains intact, baru trees included, resulting on a thinning of the water tables, worsened by industrial irrigation. The impact of this deforestation is mostly ignored by official authorities, although widely published internationally.

Remember the 90s? Did you ever wonder how come nobody talks about saving the rainforest as much anymore? The deforesting of an exuberant biome such as the Amazon brought a lot of international bad rap to Brazil. This caused the inevitable trickling of such a large industry to the neighbouring, more discrete Cerrado.


Once Cerrado, now soy crops

The Cerrado deforestation is the direct result of decades of Brazilian government policies. Since the 1990’s, this deforestation has been intimately associated with the industrial agriculture lobby machine. Over time, every sort of incentive was provided to “develop” what now is the country’s main grain belt for export commodities.

Ironically, the exporting of baru seeds is only possible nowadays due to a direct result of those incentives. It is the recent development of Midwestern Brazil’s roads that enabled baru to become a “thing”.

The current interest in baru has stimulated local communities to shift attention from commodities. Revenue from the fruits and seeds is an important and renewable incentive to preserving trees. It concentrates local efforts on reforesting the Cerrado with baru and other native species. However, most of the damage is still caused by large trading companies.

The next post in this series will address the people living in the Cerrado, and their vulnerability to the hostile Brazilian agribusiness environment. See you then!
