Until recently, the massive development of industrial and smallholder oil palm (Elaeis guineensis Jacq.) plantations has generally been conducted according to the monocrop model. However, alternative cropping systems have emerged, based on more diversified systems that combine various crops within the oil palm plots. By giving this plant a status equivalent to that of a tree, these practices correspond to agroforestry systems. In the present study, 39 agroforestry systems were identified worldwide through a preliminary literature review, a review of NGO websites and expert surveys. Our results reveal five different types of oil palm agroforestry systems: (i) associations with livestock during the production phase of the oil palm; (ii) traditional African palm and food crop systems sustained over time; (iii) associations with food crops during the juvenile phase of the oil palm; (iv) systems developed by family farms that permanently associate other plants; and (v) prototype designs developed by research institutions, often at the request of local agricultural enterprises. The spatiotemporal description of these systems enabled us to identify associated ecosystem services. Building on various proposals of biodiversity insertion in a monoculture to convert it into an agroforestry system, the present study offers new perspectives for the sustainable development of palm oil production.

The evolution of family farming cannot be analyzed only from the perspective of production. Since it is also a kinship unit, the family farm reveals social tensions that contribute to the migration of young people, especially for young women. This study presents an analysis of the factors that contribute to this migratory process, considering youth and gender variables. The analysis is based on a participatory diagnosis, multisectoral interviews and surveys in thirty-three communities located in the center of the Ceará State (Northeastern Brazil). The research reveals that the main factor of this migratory process is the lack of appreciation of family farming by the qualified rural youth, who participate little in decision-making. When the analysis of the migration is gender-focused, the invisibility of young women productive and reproductive work stands out as the main driver of migration to urban areas and proves to be greater than for young men. Rural youth migration will shape the rural territory and will probably change the format of family farming. Understanding its factors may help to propose public policies more adapted for family farming.

We review interactions between crop protection practices (developed to control plant pathogens and invertebrate pests) and human fungal infectious diseases. Unlike viral, bacterial and parasitic infections, fungal infections in humans are usually only superficial in healthy individuals, but can become invasive and pose serious risks to immunosuppressed individuals. Although their global impact is less than that of other infectious diseases, human fungal infections still pose serious public health issues. For instance, the use of synthetic agricultural fungicides, particularly the azole class, under conventional intensive, or efficiency improvement-based crop protection practices, is at risk as far as antimicrobial resistance is concerned, due to cases of cross-resistance to clinical azoles used to treat pulmonary aspergillosis, candidiasis and cryptococcocis. In this respect, the One Health approach, originally designed for other types of human pathogens, looks relevant for human pathogenic fungi. Additionally, some entomopathogenic fungi used as biocontrol products against crop pests in a substitution-based approach, may be potentially pathogenic to humans. Very few examples of redesign-based practices (i.e. Agroecological Crop Protection) emerged from our analysis on human fungal diseases. However, discontinuing agricultural azole fungicides (as practiced on organic farms, and which may to some extent be related to the redesign strategy) appears to be the best way to reduce selection pressure and hence the level of azole-resistant human pathogenic fungal strains in the environment.

This article offers a case study in Battambang province that examines agrarian and land dynamics in an irrigated command area. Building on the “powers of exclusion” framework developed by Hall, Hirsch and Li, we show how irrigation reshapes socio-spatial configurations locally and reinforces the dynamics of social differentiation between smallholder farmers. We argue that the uneven geography of water and the transformation of land ownership structures to which the irrigation project in question contributes run in the opposite direction of a pathway that would support the development of inclusive pro-smallholder irrigation.

In many countries, the challenge of sustaining rural water supplies is entrusted to community organizations, which have difficulties in performing durably the operation, maintenance and cost recovery of rural water supply systems. This paper analyzes how rural communities struggle to ensure a sustainable access to water, while seeking close interaction with outside actors such as the State, NGOs, and politicians. The analysis is based on field observations, interviews and participatory workshops in four community-managed water supply systems in Brazil and Tunisia. To sustain the access to water, communities limit their dependance on community-managed water supply systems and diversify water sources for different uses; they adapt the technical and organizational dimensions of water supply systems through bricolage; and use political leverage to obtain financial and technical support. Understanding how communities adapt the infrastructure and the organization of rural water supply, in close interaction with external actors, may inspire water providers in designing more resilient water systems.

This paper reviews the progress in climate change adaptation and mitigation actions in sub-Saharan Africa farming systems. Farmers, organizations and Governments in the region have developed policies and innovations to adapt to and mitigate the impacts of climate change. It appears that the developed and implemented innovative adaptive farming systems and technologies have culminated into resultant overall productivity improvement in farming systems, necessitating scaling up in order to widely strengthen the resilience and adaptive capacity of vulnerable communities to the impacts of climate change. Additionally, climate governance instruments that are aligned to the ratified international treaties have been developed and related programs have been rolled out in different countries. This offers hope for well-coordinated efforts and interventions for the mitigation and adaptation to the adverse impacts of climate change on the environment and livelihoods. Observably, there is a pressing need to scale up climate smart innovations sustainably through creation of an enabling policy environment, capacity building, and conducting climate change related research and outreach, and effective dissemination of climate technologies and information, especially in remote areas in the region. Since climate change is a global issue, local initiatives and actions for mitigating and adapting to the adverse impacts ought to be well integrated into the broader international context.

This data paper presents a survey conducted in a participatory manner in the territory of Santarém, in the Brazilian Amazon. The aim is to understand how global changes are affecting family farmers. In the study area, family farming has been confronted over the past 20 years with the rapid expansion of large-scale monocultures, especially soybean. As part of the Odyssea socio-environmental observatory, academic researchers and family farming organizations entered into a partnership to co-produce data that could be strategically useful for these organizations. A process of co-construction of the expectations allowed priorities to be established and the data collection strategy to be defined. Three levels of analysis were chosen in order to allow an integrated understanding of the dynamics of change: the Santarem Plateau territory, the rural community level (living place recognized by the farmers) and the farmers’ households. Twenty-one farmers, called community researchers, organized in 3 teams, applied a questionnaire through the KoboCollect smartphone application to 544 families in the municipalities of Santarém, Mojuí dos Campos and Belterra. Meetings were previously held in the rural communities and questionnaires were applied with representatives of 32 communities. Data was collected between April and June 2019. The community researchers and academic researchers then came together for two collective sessions of data analysis and interpretation in July and October 2019. Data was standardized and cleaned using SPSS software, between September and December 2019. The metadata and databases are available on the CIRAD dataverse.

In the semi-arid lands of southern Kenya, a dynamic process of farmer-led irrigation has developed over the past two decades. It is characterised by short-term agreements to access land and water. Resident and migrant farmers, capital providers and local landowners have engaged in diverse partnerships to benefit from water and land along the Olkeriai sand river. This study aims to unravel which actors and motives drive the resulting highly dynamic forms of irrigation. Surveys, in-depth interviews and mapping exercises with farmers, capital providers and landowners were conducted over a period of 1.5 years. The results show that involved actors favour short-term lease and partnership arrangements and farmers frequently change fields along the river or leave the area and return. It is primarily the migrant farmers and capital providers who take decisions on when and where to move. They are informed by their experience with production factors, financial gains and losses, partner relations, or the ability to expand. We conclude that individualisation of land rights, migration, abundance of water, proximate markets, and rural-urban networks are instrumental to the emergence of this dynamic form of agriculture. Farmers have found a degree of security in flexibility, to access land and water in shifting fields and partners, rather than in property rights for specific plots. Yet, the short-term scope of these operations for monetary gains raises concerns about the sustainable use of land and water resources in the region.

Oil palm plantations face important challenges in terms of balancing agricultural productivity and environmental sustainability. This research synthesis aims to answer key questions regarding the state and knowledge gaps of oil palm (OP) research and technological development (R&D) at a global scale, in Latin America and in Mexico, using all Web of Science® databases and agriculture categories and time spans between 1960 and 2018. Three thousand nine hundred and forty-eight publications were analysed. The research themes started with the generation of agronomic knowledge in 1960. Since 1963, studies in Latin America have focused on yield improvement; since 2010, topics related to agroecology, product quality, health issues, biodiversity, conservation impacts, and biofuel uses have been widely integrated, although some relevant themes are lacking. In addition, considering the high domestic demand for crude palm oil and great available natural resources, few Mexican institutions have participated in publications registered in Web of Science (WOS) on this topic. This research proposes a quick exploratory and reliable instrument for evaluating the agronomic interest of any agricultural production system.

The problems of malnutrition constitute a major challenge in South Africa, particularly affecting the underprivileged populations of the Eastern Cape and Limpopo provinces. The present study aimed to gain an understanding of how to improve the nutritional intake of South African university student mothers and their children by the introduction of Moringa oleifera in their food. Focus Group Discussion was implemented at two previously historically disadvantaged universities with predominantly black student populations, namely the University of Fort Hare and the University of Limpopo. Findings from the participants’ discussion about food habits and barriers to healthy eating show that there is a gap between healthy eating knowledge and eating habits. Despite the high level of awareness of the importance of nutritional intake, most of the study participants and their children consume less healthy foods. Due to the high cost of healthy food and their limited income, student mothers face substantial financial constraints when trying to make healthy changes in their food habits. Moreover, student mothers’ positive beliefs about the nutritional benefits of Moringa are insufficient to encourage its consumption. Finally, student mothers agree about using Moringa as a nutritional supplement. Maize porridge (pap) appears to be the preferred staple food for Moringa supplementation because of its palatability, satiating power, availability, affordability, and ease of preparation.
