'Missed target on deforestation'
Aside from a general consensus on the need for shared global responsibility, some environmentalists and political observers say that the Belem Declaration missed the opportunity to unite behind the issue of deforestation.
Forest protection commitments have been uneven previously and appeared to remain so at the summit.
For instance, the declaration did not include shared commitments to zero deforestation by 2030.
Brazil and Colombia have already made those commitments but other Amazon nations have not.
Lula has said he hopes the document will be a shared call to arms at the COP 28 climate conference in November.
Deforestation in the Amazon is driven mainly by cattle ranching, though it is fueled by a murky mix of corruption, land-grabbing and organised crime whose tentacles extend to the illegal trafficking of drugs, arms, timber and gold.
In Brazil, the world's top exporter of beef and soy, the destruction has already wiped out around one-fifth of the rainforest.
Some scientists have warned that when 20 to 25 percent of the forest is destroyed, rainfall will dramatically decline, transforming more than half of the Amazon rainforest to tropical savannah - essentially treeless and just full of grass - with immense biodiversity loss.
As part of the agreement, Colombian Environment Minister Susana Muhamad called for the final declaration to include a goal of preserving 80 percent of the Amazon by 2025, in line with the demands of many indigenous groups based in the forest.
Oil drilling, a sticking point
Another key sticking point dividing the Amazon nations is oil drilling.
Notably, leftist Colombian President Gustavo Petro called for an end to oil exploration in the Amazon — an allusion to the ambivalent approach of Brazil and other oil-producing nations in the region like Venezuela — and said that governments must forge a path toward “decarbonised prosperity.”
"A jungle that extracts oil — is it possible to maintain a political line at that level? Bet on death and destroying life?" Petro said.
Lula, who has presented himself as an environmental leader on the international stage, has refrained from taking a definitive stance on oil, citing the decision as a technical matter.
Meanwhile, Brazil’s state-run Petrobras company has been seeking to explore for oil near the mouth of the Amazon River.
In Ecuador, the country is due to hold a referendum this month on whether to stop drilling for crude on a strategic oil block located within the Yasuni Indigenous reservation, the source of 12 percent of the country's oil output.
Other highlights include:
Condemnation of the proliferation of protectionist trade barriers, which signatories said negatively affects poor farmers in developing nations and hampers the promotion of Amazon products and sustainable development.
It also called on industrialised nations to comply with their obligations to provide massive financial support to developing nations.
The Amazon nations also called for the strengthening of law enforcement cooperation among member states.
The signatories also committed to exchanging best practices and intelligence about specific illicit activities, including deforestation, human rights violations, trafficking of fauna and flora and the sale and smuggling of mercury, a highly toxic metal widely used for illegal gold mining that pollutes waterways.
Brazil is also calling for the summit to create an international police task force for the region and a scientific research group modelled on the Intergovernmental Panel on Climate Change (IPCC), the advisory board to the UN climate talks.
