KAKUMA, Kenya, Jun 6 2025 (IPS) – Char Tito is hammering nails into wood at Kakuma Arid Zone Secondary School in Turkana County, northern Kenya. The 16-year-old is making a traditional chair under the scorching sun outside one of the classroom blocks.


The wood she is using is from an unpopular source in this community. It is from a species of mesquite named Prosopis juliflora, which is native to Central and South America and is known in Kenya as mathenge.

Many locals hate mathenge in Turkana County due to its invasiveness and its thorns that are harsh to humans and can cause injuries to livestock. Locals say rivers and dams dry fast in areas with mathenge, and it dominates other plants.

Over the years, the residents have found it an easy source of firewood and charcoal, fuel for many in this community.

But youths, including girls, are now repurposing the mathenge tree to make furniture, particularly chairs.

“Plastic chairs are expensive. This is why I started making chairs from mathenge earlier this month,” says Tito, who fled the war in South Sudan to seek refuge in Kakuma Refugee Camp in 2017.

“I was taught here at school. Mathenge is abundant. We have been using it for firewood for years. I did not know that it could be used to make chairs.”

Income-Generating Scheme

The land in Kakuma is barren with sparse vegetation and the soils are so poor that they do not support agriculture. Turkana County receives little or no rain and can go for five years without experiencing a single drop of rain.

Acacia trees and mathenge, which are always green despite the high temperatures and water scarcity, make up most of the trees in this community.

Government statistics indicate that the mathenge trees spread at a rate of 15 percent yearly and have so far colonized a million acres of land in Kenya.

Some use mathenge to fence their homes and to make livestock shelters.

Locals survive on livestock production and trading charcoal and firewood.

Dennis Mutiso, a deputy director at Girl Child Network (GCN), a grassroots non-governmental organization supporting Tito and hundreds of other refugees, says the project is equipping learners with green skills.

“It is contributing to national climate plans. It aligns with the school curriculum,” he says.

Mutiso says those youths who have been trained in making chairs partner with those untrained to pass the knowledge to the community.

Tito, who lives with her mother and her three siblings, is so far making chairs for household use but is planning to make some for sale to her neighbors.

“This is a skill that I can use for my entire life. I am looking forward to earning a living out of carpentry,” she says, smiling.

Mathenge was introduced in the 1970s in the East African country to restore degraded dry lands. It is drought resistant, with its deep roots making it ideal for afforestation in areas like Turkana. The mathenge restored the area and blocked wind erosion in some areas, but at a cost to the locals.

Despite the massive cutting down of this tree for firewood and charcoal, the mathenge regenerates fast, unlike other trees like Acacia.

Lewis Obam, a conservator at the Forestry Commission under Turkana County, says there was a negative perception of the mathenge in the community.

“Communities lost their goats after consuming the tree. Its thorns were affecting the community,” he says.

Obam says mathenge is a colonizer and spreads so fast.

“It was meant to counter desertification. The intention was good,” he says.

Obam says its hardwood is ideal for making chairs.

“It has more opportunities than we knew. It has the second hardest wood in this area. We need maximum use of the mathenge.”

Protecting Environment 

To restore other trees in this semi-arid land, Tito and other girls are planting trees at school and in their homes. She has planted five trees at home and many at school, but water is a challenge amid temperatures that can go as high as 47 degrees Celsius.

“I am proud that I am contributing to measures that reduce the effects of climate change,” she says.

Sometimes, the girls bring water from home to school to ensure that the trees survive.

Trees help mitigate climate change by absorbing carbon dioxide from the atmosphere.

Kenya is targeting to plant at least 15 billion trees by 2032 through its National Tree Growing Restoration campaign launched in December 2022.

Magdalene Ngimoe, another learner at Kakuma Arid Zone Secondary School, says she has so far planted two trees at her home in Kiwandege village in Kakuma.

“I hate mathenge. It makes our lives difficult. But I am happy that I am using it to make chairs. I am also planting trees at school, which will provide shade to other students,” says the 16-year-old Kenyan Ngimoe, the firstborn in a family of seven.

Her family survives on selling meat and she hopes she will earn some money from her newly acquired craft.

Edwin Chabari, a manager at Kakuma Refugee Camp under the Department of Refugee Services, says Mathenge has been a menace not only within the camp but also in the area.

“The local youths can get cash from a tree that we thought was a menace,” he says.

GCN, with funding from Education Above All, a global education foundation based in Qatar, has so far planted 896,000 trees in Kakuma and Dadaab and is targeting 2.4 million trees by next year.

Ngimoe’s favorite subject is science and she wants to be a lawyer representing vulnerable children.

Established in 1992, Kakuma Refugee Camp is home to 304,000 people from more than 10 countries, like South Sudan, Burundi, Somalia, and the Democratic Republic of Congo (DRC).

Joseph Ochura, sub-county director in Turkana County under the Teachers Service Commission (TSC), says the tree-planting initiative has enhanced the learning environment.

“When you visit most of the schools that have been supported, you will see big shades of trees. Whenever there is a break time, learners sit there, including the teachers. Sometimes, some lessons are even carried out under that shade,” Ochura says.

He says that of the 15 billion trees set by the government, TSC was allocated 200 million trees.

Some schools also have their tree nurseries.

When ready, they plant the seedlings at the school and supply others to the community.

“Some of the girls are at the forefront in tree planting. That is a plus. That is what we are telling the girls—outside school, you can still do this in the community,” Ochura says.

Tito, whose favorite subject is English and who wants to be a doctor, is happy to be part of the green jobs being created in Kakuma.

“As a girl, I am proud of myself. I am contributing to environmental protection,” she says.

‘We Are Witnessing Ecocide in West Papua, One of the World’s Richest Biodiversity Centres’

Active Citizens, Asia-Pacific, Biodiversity, Civil Society, Crime & Justice, Economy & Trade, Environment, Featured, Food and Agriculture, Headlines, Human Rights, Indigenous Rights, TerraViva United Nations

May 29 2025 (IPS) – CIVICUS discusses the devastating impact of palm oil extraction in West Papua with Tigor Hutapea, legal representative of Pusaka Bentala Rakyat, an organisation campaigning for Indigenous Papuan people’s rights to manage their customary lands and forests.


Tigor Hutapea

In West Papua, Indigenous communities are boycotting palm oil products, accusing major corporations of profiting from environmental devastation and human rights abuses. Beyond environmental damage, Indigenous leaders are fighting what they describe as an existential threat to their cultural survival. Large-scale deforestation has destroyed ancestral lands and livelihoods, with Indonesian authorities enabling this destruction by issuing permits on contested Indigenous territories. Local activists characterise this situation as ecocide and are building international coalitions to hold companies and government officials accountable.

What are the problems with palm oil?

In West Papua, one of the world’s richest biodiversity centres, oil palm plantation expansion is causing what we call ecocide. By 2019, the government had issued permits for plantations covering 1.57 million hectares of Indigenous forest land to 58 major companies, all without the free, prior and informed consent of affected communities.

The environmental damage is already devastating, despite only 15 per cent of the permitted area having been developed so far. Palm oil plantations have fundamentally altered water systems in regions such as Merauke, causing the Bian, Kumbe and Maro rivers to overflow during rainy seasons because plantations cannot absorb heavy rainfall. Indigenous communities have lost access to forests that provided food and medicine and sustained cultural practices, while monoculture crops have replaced biodiverse ecosystems, leading to the disappearance of endemic animal species.

How are authorities circumventing legal protections?

There’s unmistakable collusion between government officials and palm oil companies. In 2023, we supported the Awyu Indigenous people in a landmark legal case against a Malaysian-owned company. The court found the government had issued permits without community consent, directly violating West Papua’s special autonomy laws that require Indigenous approval for land use changes.

These actions contravene national regulations and international law, including the United Nations Declaration on the Rights of Indigenous Peoples, which guarantees the right to free, prior and informed consent. Yet despite clear legal violations, authorities continue defending these projects by citing tax revenue and economic growth. They are clearly prioritising corporate profits over Indigenous rights and environmental protection.

The government’s response to opposition is particularly troubling. There is a systematic pattern of human rights violations against people defending their lands. When communities protest against developments, they face arbitrary arrests, police intimidation and violence. Police frequently disperse demonstrations by force, and community leaders are threatened with imprisonment or falsely accused of disrupting development. In some cases, they are labelled as separatists or anti-government to delegitimise their activism and justify repression.

What tactics are proving effective for civil society?

Indigenous communities are employing both traditional and modern resistance approaches. Many communities have performed customary rituals to symbolically reject plantations, imposing cultural sanctions that carry significant spiritual weight in their societies. Simultaneously, they’re engaging with legal systems to challenge permit violations.

Civil society organisations like ours support these efforts through environmental impact assessments, legal advocacy and public awareness campaigns. This multi-pronged approach has gained significant traction: in 2023, our Change.org petition gathered 258,178 signatures, while the #AllEyesOnPapua social media campaign went viral, demonstrating growing international concern.

Despite these successes, we face an uphill battle. The government continues pushing ahead with new agribusiness plans, including sugarcane and rice plantations covering over two million additional hectares of forest. This threatens further environmental destruction and Indigenous rights violations. Supporters of our movement are increasingly highlighting the global climate implications of continued deforestation in this critical carbon sink region.

What specific international actions would help protect West Papua?

Consumer power represents one of our strongest allies. International consumers can pressure their governments to enforce laws that prevent the import of products linked to human rights abuses and deforestation. They should also demand companies divest from harmful plantation projects that violate Indigenous rights.

At the diplomatic level, we need consistent international pressure on Indonesia to halt large-scale agribusiness expansion in West Papua and uphold Indigenous rights as defined in national and international laws. Foreign governments with trade relationships must make human rights and environmental protection central to their engagement with Indonesia, not peripheral concerns.
Without concerted international action, West Papua’s irreplaceable forests and the Indigenous communities who have sustainably managed them for generations face an existential threat. This isn’t just a local issue: the destruction of one of the world’s most biodiverse regions affects us all.

UNITED NATIONS, May 28 2025 (IPS) – A greater understanding and appreciation of the world’s oceans is needed to protect them. As the global community prepares to convene for the ocean conference, they must also prepare to invest in scientific efforts and education that will bolster their joint efforts.


France and Costa Rica will co-host the 3rd United Nations Ocean Conference (UNOC3) in Nice, France, from June 9-13. Over the course of the week, governments, the private sector, intergovernmental groups, and non-governmental groups, among others, will convene over the urgent actions that need to be taken to promote the conservation and sustainable use of the oceans.

This year’s conference will be the first to take place during the UN Decade of Ocean Science for Sustainable Development (2021-2030), which brings together stakeholders in which the UN and its partners will oversee the actions that need to be taken to protect the oceans’ unique ecosystems and biodiversity and how to promote greater awareness and research into ocean sciences and how to better protect them.

UNESCO’s Intergovernmental Oceanographic Commission (IOC) oversees and tracks the progress of the UN Ocean Decade, which brings together the global ocean community on the principles of understanding, educating, and protecting the oceans.

There will be an emphasis on strengthening the data-collection capacities in the global system for observing the ocean. Data scarcity and limitations in collection methods have meant that organizations have challenges grasping the full scope of the ocean and the changes they face in the wake of climate change.

Julian Barbiere, UNESCO’s Head of Marine Policy, told reporters that science-based discussions will be at the core of UNOC. For UNESCO, there will be discussions over how to translate scientific facts into tangible climate actions. This includes scaling up the current efforts at ocean-floor mapping. At present, only 26.1 percent of the seafloor has been mapped out by modern standards, with the goal to have 100 percent of the seafloor mapped out by 2030.

Joanna Post, head of the IOC’s Ocean Observations and Services, remarked that there is a “real need for recognition” of the critical functions that the system performs, such as in monitoring weather conditions, mapping the ocean floor, maritime security, and disaster risk management. She announced a new initiative that would mobilize at least 10,000 commercial and research ships to collect data and measure the ocean. Commercial and research ship vessels play a key role in tracking and collecting data on the oceans, which Post emphasized must be shared across global channels.

UNESCO’s agenda for this forum also includes encouraging stakeholders to invest in and strengthen global education efforts on the ocean. “Education is key if we want to have a new generation that is aware of the importance of the ocean system,” said Francesca Santoro, a senior programme officer in UNESCO, leading the Ocean Literacy office.

Santoro stressed that education is not limited to students and young people; private investors should also be more aware of the importance of investing in the oceans.

UNESCO aims to continue expanding the networks of schools and educators that incorporate ocean literacy into their curricula, especially at the national level. Ocean literacy emphasizes the importance of the ocean for students, educators, and local communities within multiple contexts.

One such programme is the SEA BEYOND initiative, in partnership with the Prada Group, which provides training and lessons to over 20,000 students in over 50 countries. Under that initiative, a new multi-partner trust fund will be launched at UNOC3 on June 9, which will be used to support projects and programs that work toward ocean education and preserving ocean culture. As Santoro noted, “For many people and local communities, the main entry point to start interest in the oceans… is in [identifying] what UNESCO calls ‘intangible cultural heritage.’”

Human activity, including pollution, “directly threatens” the health of the ocean, according to Henrik Enevoldsen from UNESCO-IOC’s Centre of Ocean Science.

He announced the development of a new global assessment, led by UNESCO and the UN Environment Programme (UNEP), on marine pollution, to be launched on June 12.  This would be a “major leap forward,” Enevoldsen remarked, adding that this assessment would be the first of its kind that provided a global overview of ocean pollution.

Indispensable—Native Hawaiian Elder Says of Indigenous Ocean Management Systems

BUSAN, Korea, Apr 30 2025 (IPS) – Indigenous people play a vital role in ocean protection due to their deep-rooted connection to the marine environment and their traditional knowledge of sustainable resource management. They often possess centuries-old practices and stewardship ethics that prioritize ecological balance and community well-being.


Recognizing and supporting indigenous leadership in ocean conservation is crucial for building a more sustainable future for the world’s oceans. Solomon Pili Kaho’ohalahala from the Maui Nui Makai Network spoke to IPS during the 10th Our Ocean Conference in Busan, Korea.

“My name is Solomon Pili Kaho’ohalahala. I am from the small island of Lanai in Hawaii. I’m an eighth-generation Lanai. As an indigenous Hawaiian, one thing that is really clear is that I grew up with the traditional practices of our kupuna, our ancestors, and our elders. These practices brought us into a very close relationship with the land and sea, and we learned to strike a balance between what we gather from the land and sea for our daily sustenance and what is left behind for future generations.

“This practice is very mindful of spawning seasons for our land and sea resources, whether they be plants, animals, or fish, and respects those seasons so that we leave them alone when they’re at their highest ability to perpetuate their species. By contrast, now that we are illegally a part of the United States, they have put their management systems and laws in place, and their systems are contrary to those of traditional Hawaiian practices.

“And what we find is that under their management, the resources are in decline. So, the number of fish, which I previously described as plentiful, is now declining. The seaweed, which is also a type of food for us, is declining.

“So, what we have asked the government, the state of Hawaii, is to allow the indigenous people to begin their own traditional management practices to help restore. The government has such a hard time allowing the indigenous people to be the caretakers and managers, even though we have thousands and thousands of years of experience, but the government wants to do it alone and push us aside. By excluding indigenous people, the government is failing.

“We therefore decided that we don’t need the government’s permission to be the caretakers of our resources. So, we created our own community of managers of our resource, and these are cultural people. We are applying our cultural practice from land and into sea and ensuring that all of these natural resources on land and underwater are cared for in their proper manner, and this ensures that the cycle of replenishment is not broken.

“And what we’ve been able to demonstrate is that we are finding success, but the government does not acknowledge this success. So, we are still not recognized as the people that should be the caretakers of these systems, because the experience is an indigenous one and this is a problem.

“We are hoping for opportunities where the government will allow the community to be the caretakers. It’s slow in coming, and we don’t have much time to implement this, because if we don’t, then we may lose our resources forever, and that would be a sad day. So, we are doing our part with our own initiatives, but we are also pushing the government to consider these traditional practices of the indigenous people as management practices in islands in the largest ocean on the planet.

“And it’s very slow, but we are not stopping. We are moving ahead. Now, we want to take that experience and elevate this conversation in the international arena, because now we are talking about not just an island where I live on, but I’m talking about the entire ocean in which I live in.

“And if the international bodies consider making rules and regulations to manage that large ocean without the indigenous people, then we would be creating something not any different from what I’ve been living with, where state governments try to manage and control without indigenous input. At the international level, we are asking, are you going to manage and control the large oceans of the earth without the indigenous people? It cannot be.”

BUSAN, Korea, Apr 30 2025 (IPS) – Participants from over 100 countries will leave the 10th Our Ocean Conference in Busan, the Republic of Korea, with stark reminders that with sea levels rising dangerously, coastal regions and low-lying areas globally, particularly densely populated areas, are threatened.


Asia, Africa, island nations, as well as the U.S. East and Gulf Coasts are increasingly on the frontlines of the coastal climatic carnage. Countries and regions at high risk include Bangladesh, India, the Philippines, and Pacific Island nations like Tuvalu and Fiji. In 2024, floods caused the highest number of fatalities in Africa in countries such as Cameroon and Nigeria.

“We started this conference with the understanding that the ocean is under threat. A third of the world’s fisheries are overfished. Illegal and destructive fishing is damaging the ecosystems. It hurts the coastal communities that depend on it and undermines global economies. So, to risk the ocean risks the future security of all of our countries and the planet,” said Tony Long, CEO, Global Fishing Watch.

The Our Ocean Conference gathered approximately 1,000 global leaders from various sectors, including heads of state and high-level government officials from over 100 countries, and representatives from more than 400 international and non-profit organizations. Together, they discussed diverse and concrete actions for a sustainable ocean.

Today, experts highlighted the intersection of the ocean, climate, and biodiversity in finding solutions that transform science into political action. While the ocean is on the frontlines of the climate crisis, it is also a significant source of sustainable solutions because it absorbs nearly 25 percent of carbon dioxide emissions and 90 percent of the heat resulting from these emissions.

The 30×30 campaign supports the national and global movements to protect at least 30 percent of the blue planet’s land, waters, and ocean by 2030. While moderating a session on the importance of 30×30 and progress in national waters, Melissa Wright, a senior member of the environment team at Bloomberg Philanthropies, where she leads the Bloomberg Ocean Initiative, spoke about ongoing support for the global ambition.

“We’re supporting global ambition to achieve 30×30 in the ocean through equitable and inclusive partnerships and initiatives with civil society, governments, indigenous and community groups, and local leaders. Since 2014, the Blue Water Ocean Initiative has invested more than USD366 million to advance ocean conservation,” she said.

The initiative works in tandem with governments, NGOs, and local leaders to accelerate the designation and enforcement of Marine Protected Areas (MPAs). Most recently, the initiative has pushed for the rapid ratification of the High Seas Treaty and ensured the creation of MPAs in areas beyond national jurisdiction.

“We do not have much time left until 2030 to achieve the 30×30. As such, we are presented with a unique and challenging opportunity for ambitious, robust enhancement to our national and global capacities for the protection, conservation, and sustainability of our oceans,” said Noralene Uy, Assistant Secretary for Policy, Planning, and Foreign-Assisted and Special Projects, Philippines Department of Environment and Natural Resources.

The Philippines is one of the 17 megadiverse countries in the world, meaning it possesses a high level of biodiversity and a large number of endemic species. The country is home to a significant portion of the world’s plant and animal species, including many unique and endemic species.

Within this context, she said an undue burden weighs on the Philippines given limited resources and other priority development objectives. Nonetheless, the country has turned to science and is making progress. The country has established marine scientific research stations strategically located in the major marine biogeographic regions of the country to provide insights and knowledge into their ocean.

They have also formulated the national ocean environment policy, stressing that as science and policy evolve according to the priorities of our country, organizational structures and knowledge systems must change as well.

To achieve the highest ambition in marine protection, the Philippines and coastal communities around the globe now have an ever-greater need for financing and technical resources. Brian O’Donnell, Director, Campaign for Nature, explained that the only available assessment of the cost of 30×30 on a global scale is now five years old.

“According to the assessment, it would cost about USD 100 billion a year to implement 30×30 both on land and in the sea and at the time of the assessment, only about USD 20 billion was being spent, leaving an USD 80 billion annual shortfall,” he explained.

“Not only do we need to ensure we get more money into this space, but that money is delivered efficiently and effectively to the people, communities, and countries where biodiversity is and those who are safeguarding it.”

O’Donnell said that, despite ongoing challenges in mobilizing financial resources, there is some notable progress. He spoke about the Kunming-Montreal Global Biodiversity Framework, adopted in 2022, which includes a target for wealthy nations to provide at least USD 20 billion annually in international biodiversity finance to developing countries by 2025, increasing to USD 30 billion by 2030.

This target aims to help developing countries implement their biodiversity strategies and action plans, particularly those in Least Developed Countries and Small Island Developing States. But O’Donnell said there is a need to change how things are done, as, unfortunately, much of the financing to developing countries is coming in the form of loans and short-term financing.

In all, he encouraged partnerships and collaboration in raising much-needed resources, such as the Oceans 5, which is dedicated to protecting the world’s five oceans. Oceans 5 is an international funders’ collaborative dedicated to stopping overfishing, establishing marine protected areas, and constraining offshore oil and gas development, three of the highest priorities identified by marine scientists around the world. Bloomberg Philanthropies is a founding partner of Oceans 5.

Looking ahead, there is optimism that by the time delegates settle down for the 11th Our Ocean Conference in 2026 in Kenya, the global community will have moved the needle in their efforts across finance, policy, capacity building, and research towards marine protected areas, sustainable blue economy, climate change, maritime security, sustainable fisheries, and reduction of marine pollution.

Mexico Bans GM Corn Cultivation in Constitutional Reform: Action Follows Trade Ruling That Ignored Evidence of Genetic Contamination

CAMBRIDGE, MA., Apr 30 2025 (IPS) – On March 17, Mexican President Claudia Scheinbaum signed into law a constitutional reform banning the cultivation of genetically modified (GM) corn. The action followed a December ruling by a trade tribunal, under the U.S.-Mexico-Canada (USMCA) trade agreement, in favor of a U.S. complaint that Mexico’s 2023 presidential decree, with broader restrictions on the consumption of GM corn, constituted an unfair trade practice by prohibiting the use of GM corn in tortillas.


The Mexican government publicly disagreed with the ruling, claiming that the three arbitrators had failed to consider the scientific evidence Mexico presented in the yearlong case. But the government chose to comply, rescinding the three specific parts of the decree deemed to limit future GM corn imports. Still, the government left intact the decree’s measures phasing out the use of the herbicide glyphosate, establishing a protocol for tracking GM corn imports into the country, and banning the cultivation of GM corn in the country.

The constitutional amendment enshrines that last measure in a more permanent manner. While GM corn has faced planting restrictions for more than a decade, the constitutional ban represents an important act of resistance and sovereignty, particularly in light of the flawed decision by the tribunal.

Trade panel fails to consider evidence

Corn is central to Mexico’s agriculture, cuisine, nutrition, and culture. Mexico is the center of origin for corn, where the crop was domesticated thousands of years ago. It remains at the core of the country’s farming, diet, and culture. As President Sheinbaum acknowledged in approving the constitutional ban on GM corn cultivation, “Sin maiz no hay pais” – without corn there is no country.

In defense of Mexico’s 2023 decree, the panel acknowledged that the government presented scientific evidence from qualified and reputable sources of “risks to human health arising from the direct consumption of GM corn grain in Mexico, and risks to native corn of transgenic contamination arising from the unintentional, unauthorized, and uncontrolled spread of GM corn in Mexico.” (That evidence is summarized in an extensive publication from Mexico’s national science agency.)

The trade tribunal dismissed concerns about such risks in its ruling, essentially giving itself a pass on reviewing the scientific evidence of human-health risks by arguing that Mexico had not conducted an approved risk assessment “based on relevant scientific principles,” a reference to prevailing international codes for such processes.

The panel also failed to evaluate the risks to native corn. Mexico presented strong evidence that GM corn has cross-pollinated native corn varieties, gene flow that threatens to undermine the genetic integrity of the country’s 64 “landraces” and more than 22,000 varieties adapted by farmers over millennia to different soils, altitudes, climates, foods, and customs.

The tribunal argued that no special protection from GM corn was needed because gene flow already takes place from non-GM hybrid varieties of corn, and GM contamination is no different from non-GM gene flow. “Mexico has not demonstrated how the threat to the traditions and livelihoods of indigenous and farming communities from GM corn is greater than the threat posed by non-native, non-GM corn,” the panel wrote. Cross-pollination from hybrid corn “could equally threaten the genetic integrity of native corn.”

Equating contamination from GM corn with that of hybrid corn is a serious misreading of the science and of Mexico’s culture. GMOs by definition – and by explicit definitions in the constitutional amendment – involve crossing species boundaries, introducing, for example, a gene from a bacterium into a corn plant to repel insects. In contrast, hybrid corn is produced by cross-breeding different corn varieties, the resulting offspring remaining pure corn, with no non-corn genes in its DNA.

Mexican farmers have a long history of developing some of their own cross-pollinated varieties, intentionally combining a native variety with a hybrid that has properties the farmer desires. Such cross-pollination has nothing in common with unwanted contamination from GM corn, imposed on farmers without their informed consent. They call it “genetic pollution.”

It can pose a long-term risk to native varieties. Transgenic traits do not always reveal themselves after contamination. That means farmers can unknowingly spread such contamination from their pollen year after year to other corn plants. Mexican researchers discovered such contamination in their 2013 survey of native corn varieties. Biotechnologist Antonio Serratos reported that some of the native varieties he found even within Mexico City had transgenic traits in their DNA.

“In Mexican fields, transgenic native maize is being created,” he told me at the time. ”If [GM] maize seeds are sold or exchanged, the contamination will grow exponentially. That is the point of no return.”

Seed-sharing under threat

The tribunal’s alternative recommendation for controlling unwanted gene flow suggested that “the informal seed exchange practices of indigenous and farming communities” was one of the “underlying issues” Mexico should address to prevent contamination instead of restricting imports.

Limiting seed-sharing is entirely at odds with the science of seed diversity and evolution, says researcher Erica Hagman, who helped prepare Mexico’s defense in the USMCA dispute. Mexico’s rich corn diversity is the direct result of millennia of adaptive practices by farmers in their fields. The tribunal’s suggestion that Mexico should limit such seed-sharing to prevent GM corn contamination runs counter to the practices of in situ conservation of agricultural biodiversity.

Mexico’s constitutional ban on GM corn cultivation ensures that such misguided reasoning will not guide public policy. The amendment was strengthened by proposals from civil society that extended the ban to new genetically engineered seeds by banning any crops “produced with techniques that overcome the natural barriers of reproduction or recombination, such as transgenics.” This limits some of the new generations of genetically engineered crops.

While the constitutional reform does not include some of the original language restricting GM corn consumption, no doubt in deference to the trade ruling, the final version shows a clear preference for non-GM crops, leaving the door open to tighter regulation.

Tania Monserrat Téllez from the Sin Maíz No Hay País coalition called the reform “a major step forward for the defense of native corn varieties, the health of the Mexican population, and the protection of Mexico’s biocultural heritage associated with corn.”
