— The joint Paraguay-Brazil Nueva Alianza 54 operation destroyed approximately 291 tonnes of cannabis and 95 hectares of cultivation in the Canindéyú department over 10 days, inflicting an estimated US$43.5 million loss on cross-border criminal structures.
— Operations unfolded in the Reserva Natural Morombi, Pindó and 7 Montes zones; forces dismantled seven narco camps and incinerated 6,300 kilograms of processed marijuana ready for distribution.
— Since the launch of the Nueva Alianza framework, more than 44,000 tonnes of marijuana have been eradicated in joint Paraguayan-Brazilian operations, with 4,500 tonnes destroyed in 2025 alone across five operational phases.
The Nueva Alianza marijuana operation concluded Sunday represents one of the largest single drug-eradication actions of 2026 in Latin America. The Secretaría Nacional Antidrogas (SENAD) of Paraguay coordinated with the Polícia Federal do Brasil, the Fuerza Aérea Paraguaya, and the Ministerio Público under a 10-day deployment targeting the Morombi Natural Reserve and adjacent forested territory in Canindéyú department, which borders Brazil’s Mato Grosso do Sul state.
The Rio Times, the Latin American financial news outlet, reports that this is the 54th edition of Nueva Alianza since the framework was formalized in 2017 under a cooperation agreement between SENAD and the Brazilian Federal Police. Paraguay operates under the principle of “shared responsibility” between the country as a cannabis producer and Brazil as the largest consumer market — a framing that has kept the operation politically sustainable across administration changes in both countries.
Nueva Alianza 54 is the largest single-operation yield since Nueva Alianza 49 in October 2025, which destroyed 218.8 tonnes in just two days in Pedro Juan Caballero. The framework is considered by the UN Office on Drugs and Crime as the largest antinarcotic operation in the world by volume of marijuana eliminated in concentrated time windows.
Inside the Nueva Alianza Marijuana Operation
The operational architecture combined ground tactical teams with helicopter-deployed aerial reconnaissance. The Fuerza Aérea Paraguaya provided the helicopter platform, while Brazilian Federal Police contributed intelligence and cross-border arrest capability. The Ministerio Público coordinated the legal framework to preserve any prosecutorial value from camp documentation.
The 95 hectares of eradicated cultivation included parcels at all stages of growth, from recently planted through harvest-ready. The seven dismantled camps functioned as production and inventory centers, and the 6,300 kilograms of processed and packaged marijuana represented the final-stage product destined for the Brazilian São Paulo-Rio distribution corridor.
The US$43.5 million valuation is conservative by SENAD methodology. Street-value calculations at final Brazilian distribution would run approximately three times that figure, but the operation’s frame is wholesale-cost capital destruction rather than retail-price seizure valuation.
The Morombi Reserve Environmental Angle
The Reserva Natural Morombi is the second-largest private protected forest reserve in eastern Paraguay and has been a primary cannabis-cultivation target for cross-border operations since the mid-2010s. The deforestation associated with clandestine cultivation is a significant environmental concern independent of the drug-trafficking dimension.
Nueva Alianza has progressively incorporated an environmental-restoration component under a parallel “Operación Bosques” framework, which seeks to stabilize cleared land and prevent immediate re-cultivation by different criminal organizations. The April operation did not include formal reforestation but cleared the ground for subsequent restoration work.
The Peña administration in Paraguay has positioned environmental enforcement as a complement to its Plan Paraguay Seguro security framework, which folds Nueva Alianza into a broader national-security architecture. The international visibility of Morombi operations has strengthened Paraguay’s standing in multilateral counter-narcotic coordination venues.
The PCC and Comando Vermelho Context
The Canindéyú cultivation economy feeds primarily into the Primeiro Comando da Capital (PCC) and Comando Vermelho distribution networks in Brazil. Both organizations have expanded their Paraguayan presence since 2020, with PCC structures now integrated into the Pedro Juan Caballero and Ponta Porã border-zone economies on both sides of the divide.
As Rio Times coverage of the Latin America drug-corridor framework has documented, Paraguay’s border-economy criminality is now regionally integrated in ways that make Nueva Alianza essentially a transnational enforcement action rather than a bilateral one.
The Brazilian 2024-2025 offensive against PCC logistics has displaced some cannabis-distribution volume toward Argentina and Uruguay, but Canindéyú remains the primary production node. A structural reduction in the Brazilian market would force the cultivation economy to reorient toward other destinations or collapse entirely — neither outcome is yet visible in the SENAD data.
The Regional Security Comparison
The Paraguay-Brazil cooperation framework contrasts with the Colombia-US framework and with the Mexico-US framework in important ways. Nueva Alianza operates without US Drug Enforcement Administration direct participation, relies entirely on sovereign Paraguayan-Brazilian resources, and produces quantifiable destruction outputs that have held politically across left-leaning Lula and right-leaning Peña governments.
The shared-responsibility framing — producer country plus consumer country acting as partners rather than one unilaterally enforcing against the other — is the diplomatic innovation that has made the operation sustainable. Other Latin American drug-cooperation frameworks have struggled with the same sustainability precisely because the producer-consumer framing has not been internalized.
As Rio Times analysis of Brazilian investment conditions has noted, the Mato Grosso do Sul and Paraná border zones benefit materially from sustained Nueva Alianza enforcement. Land value in previously displaced-cultivation areas has recovered as the cross-border criminal presence stabilizes.
What to Watch
Three variables matter for the second half of 2026. First, the timing of Nueva Alianza 55. The cadence has been approximately one major operation per quarter; a compressed cadence would signal stepped-up enforcement intention, while delays would signal budget or political pressure.
Second, the cannabis substitution question. Paraguayan cultivation has remained remarkably durable despite cumulative 44,000-tonne elimination since the framework’s launch. Cartels have been able to replant and regenerate production within 6-12 months of major operations, which raises the question of whether Nueva Alianza is producing structural reduction or recurring maintenance.
Third, the Bolivia flank. Bolivian cultivation expansion in 2025-2026 has produced a potential alternative supply source for Brazilian consumer markets.
If Paz-administration enforcement weakens or if the Chapare-origin supply grows, the substitution could undermine the Paraguayan-eradication impact. For now, that dynamic remains monitoring rather than action territory, but it is the most likely source of Nueva Alianza’s strategic limits in the medium term.
