The 2021 United Nations Food Systems Summit (UNFSS) was a call from the UN that brought together key players with the objective to provide potential solutions for transforming current food systems and increasing their sustainability, resilience, equitability, nutritional value, and efficiency. Key actors from science, business, policy, healthcare, the private sector, civil society, farmers, Indigenous Peoples, youth organisations, consumer groups, environmental activists, and other key stakeholders came together before, during and after the Summit, to review how food is produced, processed, and consumed across the world in order to bring about tangible, positive changes to the world’s food systems.The White/Wiphala Paper on Indigenous Peoples’ Food Systems (FAO, 2021a) was a critical reference, an evidence-based contribution to the 2021 UNFSS that highlights the crucial role of Indigenous Peoples and their food systems as game-changers and shows us how we can respect, better understand, and protect said systems. The paper resulted from the collective work of Indigenous Peoples’ leaders, scientists, researchers, and UN staff. More than 60 Indigenous and non-Indigenous contributions from 39 organisations and ten experts in six socio-cultural regions were received by the Global-Hub on Indigenous Peoples’ Food Systems. The Global-Hub on Indigenous Peoples’ Food Systems is a knowledge platform that brings together Indigenous and non-Indigenous experts, scientists, and researchers to co-create intercultural knowledge and provide evidence about the sustainability and resilience of Indigenous Peoples’ food systems (https://www.fao.org/indigenous-peoples/global-hub/en/), which coordinated the writing and editing of the paper through a Technical Editorial Committee.The White/Wiphala paper emphasised the centrality of a rights-based approach, ensuring Indigenous Peoples’ rights and access to land, natural resources, traditional territorial management practices, governance, and livelihoods, as well as addressing the resilience and sustainability of their foods systems. The paper demonstrates how the preservation of Indigenous Peoples’ food systems is necessary for the health of more than 476 million Indigenous Peoples globally while providing valid solutions for addressing some of the challenges humankind faces on sustainability, resilience, and spirituality.It is essential to note critical developments that have occurred since the White/Wiphala paper was published in mid-2021, the July Pre-Summit in Rome, and the September Summit in New York, followed by COP26 in Glasgow in November 2021.For example, at COP26, little attention was given to food systems, despite their contribution to the climate crisis, with responsibility for 30% of greenhouse gas emissions (FAO, 2021b). COP26 highlighted the need to focus on mitigation strategies and adaptation in the face of the current climate crisis. These strategies must include Indigenous Peoples’ food systems as game-changers for effective climate adaptation strategies that they have been testing and adjusting for hundreds of years.At the UNFSS Pre-Summit in Rome, the Indigenous Peoples’ delegation voiced their concerns and presented three key proposals: the recognition of Indigenous Peoples’ food systems as a game-changing solution; the launching of a coalition on Universal Food Access and Indigenous Peoples’ food systems; and the request to create an Indigenous Peoples’ fund. All their concerns and proposals were rejected at the Pre-Summit, including launching a Coalition on Indigenous Peoples’ Food Systems and Universal Food Access.In the aftermath of the UNFSS Pre-Summit, and thanks to the leadership of the Chair of the UN Permanent Forum on Indigenous Issues (UNPFII), Indigenous leaders following the UNFSS, seven countries, and the FAO Indigenous Peoples Unit (PSUI), timely discussions and collective work led to the creation of a new Coalition on Indigenous Peoples’ Food Systems.Thanks to the leadership of Mexico and the support of Canada, the Dominican Republic, Finland, New Zealand, Norway, and Spain, along with the support of the UN Permanent Forum on Indigenous Issues (UNPFII), the Global-Hub on Indigenous Peoples’ Food Systems, and FAO, this Coalition was announced at the New York September UNFSS Summit.The Coalition on Indigenous Peoples’ Food Systems builds upon the White/Wiphala Paper, establishing the objective of ensuring the understanding, respect, recognition, inclusion, and protection of Indigenous Peoples’ food systems while providing evidence about their game-changing and systemic nature. To support this objective, the Coalition organises its work around two main goals: Goal 1: Respect, recognise, protect and strengthen Indigenous Peoples’ food systems across the world; and Goal 2: Disseminate and scale-up traditional knowledge and good practices from Indigenous Peoples’ food systems with potential to transform global food systems across the board.

Indigenous Peoples’ and other traditional knowledge systems are often deemed to be ‘unscientific’ within conventional hierarchies of evidence-making. Science–policy processes to build a legacy from the commitments of the UN Food Systems Summit must ensure that due recognition, acceptance and prominence are given to traditional knowledge systems.

The prevalence of ovulation disorder (OD) is 3-fold higher in obese than normal-weight women. Most ODs are associated with concomitant polycystic ovary syndrome (PCOS), but obesity by itself can cause OD, through mechanisms that remain poorly documented. The literature on obese non-PCOS women with OD is sparse. The aim of the present study was to analyze a population of obese non-PCOS women with OD to shed further light on the mechanism of ovulation disorder.This retrospective observational study of infertile obese women without PCOS compared a control group without OD (n=45) to a study group with OD (n=30) (OD group). Clinical, hormonal, and ultrasound characteristics were collected between cycle days 2 and 5. Women older than 37 years and women with PCOM (polycystic ovarian morphology) or hormonal disorder were excluded.Body mass index (BMI) was significantly higher in the OD group, as were waist circumference and insulin and leptin serum levels. Conversely, serum follicle stimulating hormone (FSH) levels were significantly lower. After adjustment for BMI, only serum FSH level remained significantly different between the 2 groups. Discriminant analysis suggested that FSH may have a much stronger effect on OD than BMI.Low serum FSH level may contribute to OD in some obese women, independently of BMI. The pathophysiological mechanism of this finding and its impact on therapeutic strategies must be clarified.
