Eyhorn et al., 2019.
Agricultural practices need to change to meet the United Nations Sustainable Development Goals by 2030. How to achieve the SDGs is heavily contested. Here we propose a policy framework that triggers the required transition. Organic agriculture, although not a silver bullet, is a useful component in such strategy.
Sustainable agriculture and food systems need to provide sufficient and
nutritious food for all, while minimizing environmental impact and
enabling producers to earn a decent living. Most agree that agriculture
and food systems urgently need to change to make progress on several
Sustainable Development Goals (SDGs) while staying within planetary
boundaries1. However, the way to achieve this is intensely debated, with
two narratives dominating the discussion: incremental steps to improve
efficiency in conventional agriculture while reducing negative
externalities, versus transformative redesign of farming systems based
on agroecological principles.
The debate is polarized for good reason.
Transformative systems such as organic farming have proven
sustainability benefits, including improved soil quality, enhanced
biodiversity, reduced pollution and increased farm incomes but in
many contexts result in lower yields so that their sustainability per
unit product is sometimes questioned. Intensive conventional systems,
on the other hand, can be highly productive, but have substantial
negative externalities including biodiversity loss, soil erosion,
pollution, reduced human health and low farm incomes. In addition,
powerful agribusiness and food corporations have vested interests in
continuing the conventional agroindustrial model and in perpetuating
‘Feed the World’ narratives.
The SDGs offer an opportunity to
reconcile these divisions by focusing on the sustainability
contributions of different farming approaches and the policies that help
to accelerate the required transition. Successful transformative
systems, such as organic, push–pull and evergreen agriculture, offer
inspirational examples and an innovation space for transformation
because they are pursuing a radically different approach based on
agroecological processes. Conversely, incremental approaches, such as
precision farming and reduced-tillage, developed in conventional
agriculture inspire transformative systems to further improve their
performance. Here we argue that policies aligned with the SDGs are
needed to promote this transition.
