How seed diversity can help protect our food as the world warms

A new documentary explores the dangers that climate change poses to agriculture — and the seed savers who are working to make food systems more resilient.

Planting seeds is a radically hopeful act. Sowing a seed is predicated on the idea that there will be a future — one that will support and nurture the seed.

Join young documentary filmmaker and climate storyteller Charly Frisk as she travels across Nordic regions to meet with people who are working to preserve the diversity of the world’s seeds. She encounters seed savers recovering ancient varieties from older generations, visits farmer’s markets that are revitalizing old traditions, and tours gene banks that are working at the intersection of science and culture.

A key take-away from the film is that the seeds used to grow food have become radically less diverse since the 1900s. In place of a profusion of varieties that vary across geographic regions — or within a single field — many farmers now use agricultural systems in which plants of a single food crop are genetically similar to each other. The world has lost 75% of seed diversity among food crops since the 1900s, according to the Food and Agriculture Organization.

That lack of diversity presents a severe risk to the security of global food systems. Without seed diversity, it’s difficult for plants to adapt to pests, diseases, and changing climate conditions — a particular concern as the world warms. But the film offers hope that seed biodiversity will be preserved, ensuring our food systems are resilient to climate change — safeguarding the ancient, diverse, heirloom varieties that enrich our lives here on planet Earth.

Pesticide use and climate crisis locked in ‘vicious cycle’ backed by polluting industries

While agrochemical corporations promote “flawed solutions,” said one advocate, “we need deeper, transformative approaches to actually solve the root problems of our broken food system.”

Even though synthetic pesticides—the majority of which are derived from fossil fuels—contribute significantly to planet-heating pollution and increase the vulnerability of food systems, industrial agriculture interests continue to recklessly portray further pesticide use as a sensible response to the climate emergency’s worsening impacts.

That’s according to a recent report published by the Pesticide Action Network North America (PANNA), which details how agrochemical corporations exacerbate the climate crisis by refusing to admit that pesticides are part of the problem and instead promoting “false” solutions that enable them to keep peddling their highly profitable petroleum-based products.

The January report outlines how policymakers can help mitigate the climate crisis and build just and sustainable food systems by setting targets to drastically curb pesticide use, supporting agroecological farming practices, and protecting the rights of low-income individuals, disproportionately people of color, who are most harmed by pesticides, including farmworkers and residents of areas where the toxic substances are produced and applied.

“Governments are investing billions of dollars to address climate change, but these investments will fall woefully short unless they incorporate pesticide use reduction strategies and promotion of agroecological growing practices.”

“Reductions in pesticide use and the adoption of agroecology would decrease greenhouse gas emissions, while also reducing acute poisonings, long-term diseases like cancer, and other health impacts that rural communities face from pesticide exposure,” Nayamin Martinez, executive director of Central California Environmental Justice Network, said in a statement.

As the report explains: “Pesticides contribute to climate change throughout their lifecycle via manufacturing, packaging, transportation, application, and even through environmental degradation and disposal. Importantly, 99% of all synthetic chemicals—including pesticides—are derived from fossil fuels, and several oil and gas companies play major roles in developing pesticide ingredients.”

Pesticides, the offspring of a World War II-era marriage of Big Ag and Big Oil, help drive global warming to a greater extent than many realize, as the authors document:

Other chemical inputs in agriculture, such as nitrogen fertilizer, have rightly received significant attention due to their contributions to greenhouse gas emissions. Yet research has shown that the manufacture of one kilogram of pesticide requires, on average, about 10 times more energy than one kilogram of nitrogen fertilizer. Like nitrogen fertilizers, pesticides can also release greenhouse gas emissions after their application, with fumigant pesticides shown to increase nitrous oxide production in soils seven- to eight-fold. Many pesticides also lead to the production of ground-level ozone, a greenhouse gas harmful to both humans and plants. Some pesticides, such as sulfuryl fluoride, are themselves powerful greenhouse gases, having nearly 5,000 times the potency of carbon dioxide.

Despite mounting evidence that pesticides are helping to accelerate planetary heating, “climate change impacts are expected to lead to increases in pesticide use, creating a vicious cycle between chemical dependency and intensifying climate change,” the report notes. “Research shows that declining efficacy of pesticides, coupled with increases in pest pressures associated with a changing climate, will likely increase synthetic pesticide use in conventional agriculture. An increase in pesticide use will lead to greater resistance to herbicides and insecticides in weeds and insect pests, while also harming public health and the environment.”

That agricultural production is a substantial contributor to greenhouse gas (GHG) pollution is increasingly acknowledged, but the role played by pesticides is “infrequently addressed” and “many proposed solutions would not result in meaningful GHG emission reductions,” says the report.

It continues:

An example of a false solution is precision agriculture, which promises to reduce the use of petroleum-derived pesticides and fertilizers by using computer-aided technologies to more accurately determine need (pest presence) and then more accurately apply pesticides to intended targets. However, precision agriculture maintains a system dependent upon chemical- and energy-intensive technologies and materials, while diverting attention from and investment in more effective climate-friendly strategies in agriculture that have additional social and public health co-benefits, such as agroecology. Precision agriculture also increases the power and control of agrochemical companies, many of which own the precision agriculture platforms and the data inputted by farmers.

Another flawed solution, carbon markets, allows agribusinesses or farmers to sell carbon credits to corporations to “offset” continued greenhouse gas emissions—perpetuating reliance on fossil fuels. Carbon markets have a poor track record in terms of long-term climate mitigation, and have been shown to worsen economic and racial disparities.

Co-author Asha Sharma, organizing co-director at PANNA, said that “our new report reveals how oil and gas companies and pesticide manufacturers have followed a similar playbook—strategically promoting flawed solutions to the climate crisis, like carbon capture and storage and new digital agriculture tools, which in reality offer minimal climate benefits.”

“Corporations tout these novel technologies to protect their reputation, while they continue to profit from fossil fuels,” said Sharma. “We need deeper, transformative approaches to actually solve the root problems of our broken food system.”

The report makes the case for agroecology, which it defines as “a way of farming rooted in social justice that focuses on working with nature rather than against it.”

Agroecology “relies on ecological principles for pest management, minimizing the use of synthetic pesticides, while prioritizing the decision-making power of farmers and agricultural workers,” the report notes, adding that such an approach improves “the resilience of our agricultural systems to better withstand climate change impacts.”

The report makes three key recommendations for policymakers:

  • Establish measurable goals in climate policies to reduce synthetic pesticide use in agriculture;
  • Promote the transition to biodiverse, agroecological food and farming systems, such as by establishing and funding programs that provide increased technical assistance and incentives to farmers to adopt or continue these farming practices; and
  • In line with international law, adopt regulations that uphold and promote the rights of groups most impacted by synthetic pesticide use.

“Transitioning our agricultural systems to those that uplift ecological and social justice principles will not only help mitigate climate change, but also reduce the negative health impacts of industrial agriculture,” says the report. “While the work toward future policy and practice change continues, we can collectively support the advocacy work of impacted communities and organizations fighting for more equitable and sustainable food and farming systems right now.”

Co-author Margaret Reeves, a senior scientist at PANNA, argued that “governments are investing billions of dollars to address climate change, but these investments will fall woefully short unless they incorporate pesticide use reduction strategies and promotion of agroecological growing practices.”

Feeling out the new framework for biodiversity protection with the Kunming-Montreal pact

By Robert Nasi, Forests News

Well, they got there. After years-long delays due to the COVID-19 pandemic, a relocation from Kunming, China to Montreal, Canada, and following weeks of late-night negotiations peppered with walkouts and protests, a ‘new deal’ for biodiversity has been struck: on 19 December 2022, the Kunming-Montreal Global Biodiversity Framework (GBF) was adopted as the outcome of the 15th meeting of the Conference of the Parties (COP15) to the UN Convention on Biological Diversity (UNCBD).

The failure of the framework’s predecessor – none of the biodiversity targets set at Aichi in 2010 were reached by the 2020 deadline – added to the fraught tenure of the negotiations. The new framework isn’t perfect, as I’ll explain, but there are some important elements that, if implemented effectively and equitably, can make genuine impact.

Perhaps most notable is the target of protecting 30 percent of Earth’s land and sea by 2030. The global nature of the target means that the focus will be on the most biodiverse countries protecting key areas such as the tropical forests of the Amazon, the Congo Basin, and Indonesia – all areas where the Center for International Forestry Research and World Agroforestry (CIFOR-ICRAF) has a strong presence and strong partnerships.

Given it took the global community almost six decades to protect 17% of the planet, this is a lofty goal that will require coordinated – and careful – action. Much protected area creation in the past has been propelled by colonialist ‘fortress conservation’ approaches that fail to take the rights, territories, and contributions of Indigenous Peoples and local communities into account. Such restrictive approaches have had dire consequences for people and nature, with both biodiversity and livelihoods crumbling as a result.

As such, the strong language on these issues in the new framework – which reaffirms the protection of Indigenous rights and territories throughout its 23 targets and four goals, and purports to ensure their voice in decision-making – is to be commended, though as always it will be crucial to pay careful attention to how and if this plays out on the ground. As much of CIFOR-ICRAF’s work highlights, it’s critically important to recognize human agency in the shaping of sustainable landscapes. As a global community, we need to become more skillful at differentiating between human activity that has been harmful and natural resource use that has been, is, or can be sustainable.

On that note, the agreement to develop a multilateral benefit-sharing and funding mechanism, to help put sovereignty over digital genetic code in the hands of those in whose land and sea-scapes it resides (rather than those of biopirates and corporations) is also significant. It was heartening, too, to see a new standalone target on gender equality and women and girls’ empowerment, and the inclusion of the term ‘gender-responsive’ in place of the weaker ‘gender-sensitive’. Also welcome is the (long overdue) target of reducing harmful subsidies for fisheries, agriculture and fossil fuels by at least USD 500 billion annually by 2030: right now, at least USD 1.8 trillion of such subsidies are financing the destruction of biodiversity each year.

Among these victories, it was disappointing to see the watering-down of language promoting and centering agroecology in the framework’s sustainable agriculture target. The final text reads, “The application of biodiversity-friendly practices, such as sustainable intensification, agroecological and other innovative approaches”; sustainable intensification, however, causes significant biodiversity loss and has been shown not to stop agricultural expansion. Another concern is that over-emphasis on protected areas through the 30×30 target could take away from necessary attention on developing biodiverse, inclusive, and resilient food systems – a subject on which CIFOR-ICRAF has a combined 70 years of international experience. Agroforestry and trees on farms, for instance, can play a significant role in restoring and enhancing ecosystems while producing critical food and nutrition.

Discussions on who will foot the bill for biodiversity conservation were also fraught, and wealthier countries’ reluctance to front up prompted the walk-out of delegates from over 70 countries in the Global South at one stage. In the end, the financial target of USD 200 billion a year for conservation initiatives – a sum determined to be critical for the framework’s success – was reached, through some developing countries such as the Democratic Republic of the Congo (DRC), Brazil and Malaysia expressed disappointment that richer ones did not offer up a larger amount, and that a new fund for biodiversity was not established.

So, now that we have an agreed path towards halting the loss of species and protecting the world’s remaining biodiversity, what lies ahead? By addressing the current polycrisis  – biodiversity loss, climate crisis, growing inequalities, broken food systems, unsustainable supply chains – simultaneously through transdisciplinary science, CIFOR-ICRAF is delivering holistic solutions at scale in priority areas with the greatest potential for positive impact: sustainably managing multiple-use landscapes, promoting conservation in productive landscapes through agroecological approaches, and preserving local and global livelihoods. We will continue working to reverse negative environmental trends by generating evidence of the enormous value of trees – in forests, on farms, and across landscapes.
