Cuba's transition to agroecology is perhaps as widely known as it is misunderstood. In response to the economic crisis of the early 1990s, the Cuban agricultural sector largely departed from the industrial model of food production that it had previously pursued. The subsequent transition towards an agroecological model has been a dynamic and uneven process, elevating Cuba on the world stage as a global leader in sustainable agriculture while at the same time producing unique challenges for Cuban farmers, policy makers, researchers and academics. This article synthesizes and updates contemporary literature on the Cuban agricultural system, paying attention to both successes and shortcomings of agroecology in Cuba to date. In particular, it situates these literatures alongside contributions from academics and practitioners alike, bringing a number of data sets, experiences, and perspectives into conversation in the context of changing realities within Cuba and the nation's evolving geopolitical relationship with the United States. By analyzing both the historical and contemporary processes through which agroecology has taken root in Cuba, we demonstrate that, despite its uneven and incomplete implementation, such a sustainable agroecological transition holds great, untapped potential. Agroecology in Cuba currently faces pressure from normalizing Cuba-US relations, with potentially profound implications for agriculture in both countries. But increasing opportunities are also emerging for investment, collaboration, knowledge exchange, and solidarity. In this paper, we provide an overview of the evolution of the Cuban agroecology movement; analyze the state of food security and challenges to food sovereignty on the island today; outline US-Cuba policy changes occurring since December 2014 that may affect the agrifood sector; and conclude with recommendations for supporting agroecology -for food security, food sovereignty, and sustainability -under this new and evolving relationship.

Como respuesta a la crisis económica a principio de los 90, el sector agropecuario cubano se apartó en gran medida del modelo industrial de producción alimentaria que anteriormente había perseguido. La transición posterior hacia un modelo agroecológico ha sido un proceso dinámico y heterogéneo, que 1) ha convertido a Cuba en líder en el desarrollo de una agricultura sostenible a escala global y que, al mismo tiempo, 2) ha producido

Cuba’s experience in sustainable agriculture and agroecology has been the subject of much international attention, particularly as advocates of agroecology aim to demonstrate the feasibility of implementing alternatives to industrial agriculture on a national scale to support ecological resilience, food security, food sovereignty, and human wellbeing. Such attention has increased since relations between the U.S. and Cuba began to normalize, stimulating speculation as to how this will affect Cuba’s advances in sustainability. The Special Feature Cuba Agrifood Systems in Transition analyses the nuances of agroecological development in Cuba. We emphasized amplifying the voices of locally-based researchers and practitioners by targeting manuscript invitations to Cuban scholars and publishing in both Spanish and English. We outline the process, challenges and goals of this unique endeavor and introduce seven articles, all contributions from Cuba except for one, which is a collaboration between U.S. based and Cuba based scholars. These articles unpack some of the complexities of Cuba’s agrifood system transition and draw on specific information and experiences to discuss successes and challenges of this transition. We thus underline the instructive value of the Cuban experience regarding the path to agrifood system sustainability and hope to spark new collaborative opportunities as scholars and citizens around the world look to develop agrifood systems that will sustain human society long into the future.Please refer to Supplementary Materials, DOI: https://doi.org/10.1525/elementa.335.s1, for a full text Spanish version of this article. La experiencia de Cuba en la agricultura sostenible y la agroecología ha recibido una importante atención internacional, en especial porque los defensores de la agroecología buscan demostrar la factibilidad de implementar alternativas a la agricultura industrial a una escala nacional para respaldar la resiliencia ecológica, la seguridad y la soberanía alimentarias y el bienestar humano. Esa atención no ha hecho sino aumentar desde que las relaciones entre Estados Unidos (EE.UU.) y Cuba empezaron a normalizarse, y se está especulando actualmente sobre cómo afectará esto a los avances de Cuba en materia de sostenibilidad. Este breve artículo de introducción presenta un resumen de la publicación especial El sistema agroalimentario cubano en transición, que tiene el fin de contribuir al conjunto de publicaciones que analizan los matices del desarrollo agroecológico en Cuba, con un énfasis en amplificar las voces de los protagonistas basados a nivel local al invitar a que contribuyan académicos cubanos y publicar en español e inglés. Presentamos el proceso, los desafíos y los objetivos de este esfuerzo único y destacamos la presentación de los siete primeros artículos, todos procedentes de Cuba a excepción de uno, que es una colaboración entre académicos basados en EE.UU. y Cuba. Mediante el análisis de algunas de las complejidades de la transición del sistema agroalimentario cubano y la presentación de estudios detallados y rigurosos sobre sus éxitos y desafíos, esta publicación tiene el fin de mejorar el entendimiento de los lectores sobre el camino para lograr la sostenibilidad del sistema agroalimentario conforme a la evolución del mismo en Cuba. Con esto, esperamos subrayar el valor instructivo del caso de Cuba y generar nuevas oportunidades de colaboración,ya que académicos y ciudadanos de todo el mundo están tratando de desarrollar sistemas agroalimentarios que sustenten a la sociedad por mucho tiempo.La versión en español de este artículo se puede encontrar en Materiales Suplementarias, DOI: https://doi.org/10.1525/elementa.335.s1.
