Strengthening Ties: Brazilian Army leaders return for second environmental exchange with USAEC

In a dynamic exchange of environmental expertise, U.S. Army Environmental Command (USAEC) leaders, Commander Col. Vance Brunner and Command Sgt. Maj. Francisco Cardenas, hosted representatives from the Brazilian Army Department of Real Estate and the Environment (DPIMA) during the week of October 28, 2024, at Joint Base San Antonio–Fort Sam Houston, Texas.

The Brazilian Army delegation, led by Col. Andre Luiz Cardoso Marinho, Head of the Environmental Office, included Lt. Thaisa Sant’Anna Lacerda, Biologist/Technical Officer; 1st Lt. Joana Albuquerque Di Lucia Cerqueira Leite, Technical Translator; along with Brazilian Army Col. Sergio Matos, liaison officer, and U.S. Army Maj. Alfredo Carrillo, engineer planner, both with U.S. Army South. This visit continues the exchange of insights, fosters collaboration, and gains a deeper understanding of environmental management within military operations.

USAEC Insights and Collaborative Dialogues 

USAEC’s comprehensive presentations highlighted its mission and showcased the organization’s diverse areas of expertise, such as natural and cultural resource management, National Environmental Policy Act compliance, pest management, and the Conservation Reimbursable and Fee Collection Program (CRFCP).

The exchange underscored that, despite differences in operational contexts, the shared challenges faced by environmental professionals transcend geographic and organizational boundaries. Drawing on years of professional expertise within USAEC, the discussion highlighted common themes such as resource management, sustainability, and regulatory compliance, showcasing the universal nature of these issues and the value of collaborative problem-solving.

“It’s clear that we share many similarities in our approaches, even though we may implement them in slightly different ways,” said Brunner. “Despite these differences, we are united by a common goal: striving together toward a more sustainable future.”

Beyond the technical discussions, the camaraderie built through shared challenges, practices, and humor added a personal connection to the professional exchange. Stories of life experiences and lessons learned created a sense of community, reminding everyone that the mission is not only about overcoming obstacles but also about fostering enduring relationships along the way.

Brazil’s Unique Approach to Environmental Stewardship 

Brazil’s military integrates environmental stewardship as a fundamental aspect of national security, reflecting the nation’s deep connection to its diverse natural landscapes. Spanning six distinct biomes - from the Amazon rainforest to the Pampas - Brazilian soldiers receive rigorous training designed to equip them with the skills needed to navigate, preserve, and thrive within these unique ecosystems. This training underscores their dual role as both defenders of the nation and guardians of its natural heritage.

“To protect the environment, you have to know the environment,” implied Marinho, summarizing Brazil’s philosophy.

By fostering an intimate understanding of the country’s ecological wealth, the Brazilian military ensures that its operations not only respect but also contribute to the preservation of all the country’s vital natural resources.

The delegation emphasized Brazil’s legal framework that mandates strict protections for trees, wildlife, and biomes. For example, it is illegal to cut down a tree [without authorization] or capture or kill wildlife [unless life threatening]. This emphasis on compliance is deeply embedded in the culture of the Brazilian army.

A traditional gift exchange concluded the two-day collaboration at USAEC and continued the growing partnership between the two nations and underscored their mutual commitment to environmental sustainability.

Through a translator, Marinho expressed his gratitude on behalf of the Brazilian delegation for the opportunity to travel to USAEC and learn from the U.S. Army’s civilian environmental professionals.

Fort Cavazos: Showcasing Environmental Excellence

Following their visit to USAEC, the Brazilian delegation traveled to Fort Cavazos, accompanied by USAEC leadership team of Brunner and Cardenas. They were welcomed to the installation by Col. Lakicia Stokes, garrison commander, and Christine Luciano, environmental outreach coordinator, Directorate of Public Works (DPW) along with subject-matter experts from the DPW Environmental Division

The delegation received an overview of Fort Cavazos’ Environmental Programs, which emphasizes sustainability through compliance, conservation, and innovative recycling practices. Highlights included energy efficiency programs, renewable energy initiatives, and resource management efforts to protect ecosystems, endangered species, and cultural sites.

“A key component of Fort Cavazos' environmental policy is maintaining the balance between sustaining mission readiness and the environment,” Luciano explained, emphasizing the importance of integrating sustainability into all aspects of military operations.

The Brazilian delegation shared insights into their own resource management initiatives, enriched by indigenous Soldiers’ unique cultural knowledge. They noted parallels and opportunities for shared learning.

During tours of key facilities, the delegation observed Fort Cavazos’ innovative single-stream recycling program, pollution prevention protocols, and waste management processes, all supporting operational sustainability.

One stop included the 48th Chemical Brigade motor pool, that provided an example of how Fort Cavazos has implemented rigorous pollution prevention protocols regarding above-ground storage tanks and stormwater drainage systems to ensure they are carefully managed. These protocols are critical to maintaining both environmental compliance and operational integrity.

Adding to the experience, the delegation felt fortunate to have U.S. Army Spc. Lucas Deoliveira, a native Brazilian and Soldier with the 48th Chemical Brigade, serve as an unofficial translator during the tour of the motor pool area. His presence not only bridged the language gap but also brought a unique and personal connection to the exchange, making the experience even more memorable.

The visit concluded at the DPW Environmental Division’s - Bird, Bee, Butterfly and Bat Garden, which includes a variety of sustainable landscaping practices designed to conserve water and promote biodiversity. The garden serves as an educational space for visitors and Soldiers alike, illustrating the importance of native plant species and conservation efforts on military lands. It is a testament to the installation’s dedication to preserving local wildlife and promoting environmental education.

The Brazilian delegation was impressed by how Fort Cavazos integrates environmental conservation with operational needs. From innovative recycling to pollution prevention and resource conservation, the base exemplifies how military installations can promote sustainability while fulfilling their mission. The hands-on visit highlighted Fort Cavazos’ commitment to balancing military readiness with environmental stewardship, offering a model of sustainable practices for global partners.

Building Bridges for Future Collaboration 

This second exchange between the Brazilian Army Environmental Directorate, USAEC and Fort Cavazos Environmental Programs continues to strengthen bonds and open doors for future collaborations. The visit underscored the shared dedication of both nations to environmental stewardship and the potential for innovative, cooperative solutions to global environmental challenges.

“Together, we can create a more sustainable future for our militaries and the environments we are entrusted to protect,” said Brunner.

As the collaboration between the two nations continues to strengthen, the exchange of knowledge and shared environmental values holds the potential for a lasting impact on global military environmental management. The shared insights and practices will contribute to a deeper commitment to sustainability and foster greater cooperation moving forward.
