ACRAA Volunteers This page is dedicated to acknowledging and thanking those people that have volunteered their time in ACRAA’s nursery and in assisting in our day-to-day activities. The photos show our volunteers at work, and are presented with the most recent first – click on each to see the full-sized image.  However, not included here are the many other volunteers that have stepped forward and helped at our planting and other events – to these people we say thank you very much as well. Many of these people can be seen in photos on our project pages. A special thanks to Waldeir, ACRAA’s Professional Forester, for organizing students from UFOPA (The Universidade Federal do Oeste do Pará, Santarém), to help us at ACRAA. A big thank you to Daki as well for giving her Sundays to lead our weekly Volunteer Day at ACRAA. Comandá seedling ready to be potted. July…

Carbon Footprint Analysis In this section we discuss the “carbon footprint” associated with travelling to the amazon to participate in our (near future) reforestation tourism program [1][2]. But at the outset here, to those that would immediatey scoff at such proposition simply because, yes, this does involve air travel, we respectfully argue — you do not undertsatnd the bigger picture here. Understand the amazon region is extremely economically depressed [3]. Even before the pandemic this was the case, but now it is much worse. As a consequence there are some here in Brazil calling for much higher levels of resource extraction (minerals, logging) and expansion of industrial agriculture (esp. soya). And this is occuring – with record rates of deforestation seen in 2022. See this recent article in Guardian. And this will continue to increase, unless we find alternate “green” forms of economic development.  We see our reforestation tourism initiative…

Healing the Land with Trees There are a number of ways trees (and shrubs [1]) used in agroforestry systems cam improve soil fertility and help heal degraded land. First, many trees species used in agroforestry systems perform biological nitrogen fixation (through symbiotic associations with microbes in thier roots). This nitrogen, thus converted in organic form, is made available to other plants/crops through litterfall and nutrient cycling processes. Trees are also deep-rooted plants. As such they can access nutrients (such as nitrogen, calcium, magnesium and phosphorus) in the subsoil – these nutrients out of the reach of more shallow rooted agronomic plants. Again, these nutrients are made available to these agronomic plants through litterfall and nutrient cycling processes (this is referred to as “nutrient pumping” in the literature). The large amount of litterfall produced by trees (both due leaves and root turnover) improves soil organic matter content. This combined with the…

Building Connections For ACRAA to succeed in its objectives, alliances must be built between various local, national and international groups and organizations. This includes local indigenous groups, universities, public institutions, NGOs, community groups and people interested in the cause. We will seek to carry out projects together with educational institutions in the region and in other locations that are interested in ACRAA projects. Reforestation and agroforestry projects will be coordinated with these institutions. In the project “Escola de Campo de Reflorestamento Tropical” (Tropical Reforestation Field School), this connection with national and international universities will be fundamental for its realization, as we will seek to create a practical teaching center where students from these institutions will take courses and experiences in partnership with ACRAA. There are 13  indigenous ethnicities in the Santarém region, where we will seek to connect with each one in diversified projects. Regarding indigenous groups, the Borari are…

Education Education is the third branch of the ACRAA tree. There will be many elements to this branch, one of which is this website itself. This is because as time goes on we will include more and more detailed technical content – information that will help anyone else interested in undertaking reforestation and agroforestry projects in the humid tropics, or even replicating what we are doing here in Alter do Chão.  Another important element is the work we are doing with local schools to support education in these areas. Here we very excited about the alliance we have formed the local Borari schools here in Alter do Chão. Our first work with these schools occured on April 18 and 20, 2022 – in conjunction with celebrations in relation to Indigenous Peoples Week here. See our ACRAA at School Program to learn more. But a critical component of our educational activities will be…

About Us ACRAA is located in the village of Alter do Chão, which is on the banks of the Tapajós river in the Amazon region of Brazil (Pará state). The port city of Santarém on the Amazon River is 35 km away. We were founded by a trio made up of a Brazilian, a Canadian and a Venezuelan (Diêgo, Thor and Daki). We now have fifteen associates and we count on the cooperation of other people such as our forestry engineer, Waldeir. You will meet some of these people in the pages of this website. Together we have started the ACRAA headquarters in Alter do Chão – a resource and educational center, and nursery for reforestation and agroforestry development.  See biographies here. ACRAA’s Mission:  At ACRAA it is our mission to promote and advance the restoration and conservation of forest ecosystems in the Amazon Region of Brazil, and where appropriate…

Agroforestry Agroforestry development is the second branch of the ACRAA tree. We feel this science must be part of forest restoration efforts in the amazon, as forests that can sustain families and communities are needed to address food and economic security locally and regionally. Some, as in a recent article in the Guardian, have gone as far as to say that larger-scale reforestation (such as, for example, areas under soya cultivation in the amazon region) – without agroforestry development, will put global food security at risk. See Guardian article here. It must be noted however, and this point was not mentioned in this Guardian article – that much of the worlds grain and soya production is used to feed livestock in INDUSTRIAL meat production. If overall, globally, people consumed a more plant-based diet – less agricultural land under such monoculture production would be required. A basic definition of “agroforestry” is…

Reforestation Reforestation – the restoration of native forest and riparian ecosystems in the Alter do Chão area and greater Santarém region, is the first branch of the ACRAA tree. Alter do Chão is located in the Amazon Rainforest, and the importance of this forest to the global biosphere is becoming increasingly known. It is also a very special region as the largest freshwater aquifer in the world by volume is located here. The Alter do Chão area also draws attention for having freshwater beaches of admirable beauty, these famous nationally and internationally. In fact, in 2009 the Guardian rated the beaches of Alter do Chão as the number one “beach” in Brazil. See the Guardian article here. And it is in the restoration of the economically vital beaches around Alter do Chão that ACRAA is focusing its initial efforts, as there is an urgent need here. Specifically, this means planting…
