. In this article, we report on a process of collaboratively developing a methodological framework, using the High Level Panel of Experts of the Committee on World Food Security 13 principles of agroecology as foundation. This framework overcomes some limitations of previous methodologies for evaluating degrees of agroecological integration (including those using Gliessman’s 5 levels of food system change) and facilitates a robust qualitative assessment of projects, programs, and project portfolios with respect to their “agroecologicalness.” The framework conceives of agroecology as paradigm-shifting rather than as incremental improvements to existing food systems. It enables global comparability as well as local contextualization of each principle. While the need for this framework arose from the desire to monitor—and increase—financial support for an urgently needed transformation toward agroecology, the framework can equally contribute to the design of projects and programs, which aim to radically transform food and farming systems. It also has value as an educational tool, in specifying through statements of value and concrete examples, what agroecological work aims at.

HIDE SUMMARY VIEW ON EXTERNAL SITE

Over the past two decades, many journals have published papers describing how modifying one or a few genes can result in substantial increases in crop yields. The reported increases range from 10% to 68%, and the crops analysed include rice, maize (corn), tobacco and soya bean.

These studies have contributed important insights in molecular biology and gene discovery. But many are the results of tests conducted in greenhouses or in small-scale field trials — the latter typically involving plants grown in small plots. Few, if any, have used the experimental designs needed to evaluate crop performance in real-world environments. And hardly any findings have translated into yield increases on actual farms.

Especially in the context of climate change and a growing human population, the growth of misleading claims around yields has become a cause of concern to us.

Genetic modification can improve crop yields — but stop overselling it

Merritt Khaipho-Burch, et al.

Publication date: 20/09/2023

HIDE SUMMARY VIEW ON EXTERNAL SITE

With a changing climate and a growing population, the world increasingly needs more-productive and resilient crops. But improving them requires a knowledge of what actually works in the field.

The EU legislative framework for a sustainable food system: How can it effectively deliver for the environment and people?

Client Earth

Publication date: 08/09/2023

HIDE SUMMARY VIEW ON EXTERNAL SITE

In its Farm to Fork Strategy, the European Commission announced that it will present a legislative framework for a sustainable food system, an initiative expected for the third quarter of 2023.

The vision reflected in the law proposal will have a critical impact on the EU’s capacity to build its resilience against the worsening climate and biodiversity crises while guaranteeing long-term accessibility to healthy food.

The briefing presents solutions in the form of actionable tools that can best ensure the swift implementation of a sustainable EU food system on the ground. The European Commission must go ahead with its proposal and publish it in September 2023; there is no better time.

Beyond the Genome: Genetically Modified Crops in Africa and the Implications for Genome Editing

Joeva Sean Rock, Matthew A. Schnurr, Ann Kingiri, Dominic Glover, Glenn Davis Stone, Adrian Ely, Klara Fischer

Publication date: 01/01/2023

HIDE SUMMARY VIEW ON EXTERNAL SITE

This article makes two interventions. First, it identifies the discursive continuity linking genome editing and the earlier technology of genetic modification. Second, it offers a suite of recommendations regarding how lessons learned from GM crops might be integrated into future breeding programmes focused on genome editing. Ultimately, the authors argue that donors, policymakers and scientists should move beyond the genome towards systems-level thinking by prioritizing the co-development of technologies with farmers; using plant material that is unencumbered by intellectual property restrictions and therefore accessible to resource-poor farmers; and acknowledging that seeds are components of complex and dynamic agroecological production systems. If these lessons are not heeded, genome-editing projects are in danger of repeating mistakes of the past

Time for the end of GM/GE herbicide tolerant crops?

GeneWatch UK

Publication date: 01/08/2022

HIDE SUMMARY VIEW ON EXTERNAL SITE

The aim of this report is to look at the economic, environmental and social impacts of growing RoundUp Ready (RR) crops and newer HT crops. This report reviews more than 25 years of experience with this technology. We conclude that the cultivation of GM HT crops may be regarded as a temporary aberration, rather than the revolution originally proclaimed by the proponents of these crops. The growing failure of RoundUp Ready crops, due to the spread of glyphosate resistant (GR) weeds, provides an opportunity to phase out the use of RR crops and adopt new methods and technologies. The priority should be to reduce and replace the use of herbicides: not to replace RR crops with other herbicide-tolerant crops, whether or not these are GM crops or produced by different methods.

Why are agri-food systems resistant to new directions of change? A systematic review

Costanza Conti, Giacomo Zanello, Andy Hall

Publication date: 01/12/2021

HIDE SUMMARY VIEW ON EXTERNAL SITE

A central concern about achieving global food security is reconfiguring agri-food systems towards sustainability. However, historically-informed trajectories of agri-food system development remain resistant to a change in direction. Through a systematic literature review, we identify three research domains exploring this phenomenon and six explanations of resistance: embedded nature of technologies, misaligned institutional settings, individual attitudes, political economy factors, infrastructural rigidities, research and innovation priorities. We find ambiguities in the use of the terms lock-in and path-dependency, which often weaken the analysis. We suggest a framing that deals with interdependencies and temporal dynamics of causes of resistance. Finally, we discuss implications for framing innovation for transformational change and other research gaps.

Higher yields and more biodiversity on smaller farms

Vincent Ricciardi, Zia Mehrabi, Hannah Wittman, Dana James, Navin Ramankutty

Publication date: 25/03/2021

HIDE SUMMARY VIEW ON EXTERNAL SITE

Small farms constitute most of the world’s farms and are a central focus of sustainable agricultural development. However, the relationship between farm size and production, profitability, biodiversity and greenhouse gas emissions remains contested. Here, we synthesize current knowledge through an evidence review and meta-analysis and show that smaller farms, on average, have higher yields and harbour greater crop and non-crop biodiversity at the farm and landscape scales than do larger farms. We find little conclusive evidence for differences in resource-use efficiency, greenhouse gas emission intensity and profits. Our findings highlight the importance of farm size in mediating some environmental and social outcomes relevant to sustainable development. We identify a series of research priorities to inform land- and market-based policies that affect smallholders globally.

Broadening the GMO risk assessment in the EU for genome editing technologies in agriculture

Katharina Kawall, Janet Cotter, Christoph Then

Publication date: 11/08/2020

HIDE SUMMARY VIEW ON EXTERNAL SITE

Here, we describe the range of specific unintended effects associated with genome editing. We examine the considerable possibilities to change the genome of plants and animals with SDN-1 and SDN-2 genome editing (i.e. without the insertion of genes conferring the novel trait) and show that genome editing techniques are able to produce a broad spectrum of novel traits that, thus far, were not possible to be obtained using conventional breeding techniques. We consider that the current EU risk assessment guidance for GMOs requires revision and broadening to capture all potential genomic irregularities arising from genome editing and suggest additional tools to assist the risk assessment of genome-edited plants and animals for the environment and food/animal feed in the EU.
