West Nile virus (WNV) is a globally significant vector-borne disease that is primarily transmitted between birds and mosquitoes. Recently, there has been an increase in WNV in southern Europe, with new cases reported in more northern regions. Bird migration plays a crucial role in the introduction of WNV in distant areas. To better understand and address this complex issue, we adopted a One Health approach, integrating clinical, zoological, and ecological data. We analyzed the role of migratory birds in the Palaearctic-African region in the spread of WNV across Africa and Europe. We categorized bird species into breeding and wintering chorotypes based on their distribution during the breeding season in the Western Palaearctic and the wintering season in the Afrotropical region, respectively. By linking these chorotypes to the occurrence of WNV outbreaks in both continents throughout the annual bird migration cycle, we investigated the relationship between migratory patterns and virus spread. We demonstrate that WNV-risk areas are interconnected through the migration of birds. We identified a total of 61 species that potentially contribute to the intercontinental spread of the virus or its variants, as well as pinpointed high-risk areas for future outbreaks. This interdisciplinary approach, which considers the interconnectedness of animals, humans, and ecosystems, represents a pioneering effort to establish connections between zoonotic diseases across continents. The findings of our study can aid in anticipating the arrival of new WNV strains and predicting the occurrence of other re-emerging diseases. By incorporating various disciplines, we can enhance our understanding of these complex dynamics and provide valuable insights for proactive and comprehensive disease management strategies.

Social and environmental transformation of refugee and hosting community landscapes in Central and Eastern Africa
This paper synthesises the challenges in environmental sustainability facing refugee-hosting landscapes, on-going initiatives, and gaps. It also presents transformative science plans by CIFOR-ICRAF to address exiting gaps towards resilient landscapes and livelihoods. CIFOR-ICRAF is a research institution in forestry and landscape management, which has evolved out of an effective merger between CIFOR and ICRAF.
The assessment shows that resilience, sustainability, and environmental health in host landscapes are multi-faceted and complex, with cultural, ecological, economic, social, and political dimensions. Therefore, despite various organisations working in refugee hosting landscapes, there are still challenges in achieving holistic, long-term and sustainable solutions. On the other hand, governance and host community institutions that are central to the ownership, success and sustainability of initiatives addressing environmental degradation have not always been actively involved to date.
Women’s changing opportunities and aspirations amid male outmigration: Insights from Rural Kenya
This brief presents a study on the changing opportunity spaces of men and women in the drylands of eastern Kenya (Crossland et al., 2021). It sheds light on the dynamics of rural aspirations in relation to both gender and age within the themes of outmigration and feminisation of agriculture. Using a novel methodology combining short narratives with semi-structured interviews and focus group discussions, this research contributes to a more nuanced understanding of aspirations and the wider socio-cultural context within which they are embedded and makes several recommendations for progressing aspirations research. The purpose of the research is to provide a better understanding of people’s current situations, desired trajectories and the influences that shape these aspirations, so that researchers and development actors might better tailor their support options to meet the needs of different user groups by matching technologies to their strategies and demands.
Land Restoration Amid Male Outmigration: The Cases of Burkina Faso and Kenya
Within the global literature on ecological restoration, a subset of literature examines the relationship between smallholder land restoration and rural outmigration. However, intrahousehold dynamics surrounding the outmigration of one or more household members and the capacity of the household to undertake land restoration activities are often overlooked. With analyses rooted in Burkina Faso and Kenya, we explore the relationships between restoration, household labor, and rural outmigration, which is a prominent livelihood strategy in the two contexts. Our case studies draw on data from interviews, focus group discussions, and small-n household surveys in Burkina Faso and Kenya. Our analysis substantiates the need to consider migration in understanding and promoting smallholder land restoration. Our multi-sited approach further reveals that the contextually-specific characteristics of the migration event (i.e., type of migration [permanent or temporary], position of the migrant within the household, timing and duration of migration) play an important role in shaping restoration and gender outcomes. As male heads of households or their sons outmigrate periodically in Kenya compared to young men leaving seasonally in Burkina Faso, the impacts of migration on intrahousehold gender relations are more transformative in the Kenyan case study, with women garnering greater decision-making power on the family farm and in land restoration activities, whereas entrenched gender norms in the Burkina Faso case remain unchallenged by migration.
A Road Less Travelled by Migratory Farmers of Odisha: Innovative Agroforestry Practices
A success story of migrant farmers from Bolangir and Nuapada districts who have adopted innovative agroforestry practices, including intercropping with bio-fortified staple food crops, vegetables and an agro-voltaic system in order to come out of the migration cycle and improve food, nutritional and income security for their families.
Gendered Migration and Agroforestry in Indonesia: Livelihoods, Labor, Know-How, Networks
Migration connects land use in areas of origin with areas of new residence, impacting both through individual, gendered choices on the use of land, labor, and knowledge. Synthesizing across two case studies in Indonesia, we focus on five aspects: (i) conditions within the community of origin linked to the reason for people to venture elsewhere, temporarily or permanently; (ii) the changes in the receiving community and its environment, generally in rural areas with lower human population density; (iii) the effect of migration on land use and livelihoods in the areas of origin; (iv) the dynamics of migrants returning with different levels of success; and (v) interactions of migrants in all four aspects with government and other stakeholders of development policies. In-depth interviews and focus group discussions in the study areas showed how decisions vary with gender and age, between individuals, households, and groups of households joining after signs of success. Most of the decision making is linked to perceived poverty, natural resource and land competition, and emergencies, such as natural disasters or increased human conflicts. People returning successfully may help to rebuild the village and its agricultural and agroforestry systems and can invest in social capital (mosques, healthcare, schools).
Land use change in four landscapes in the Peruvian Amazon
This working paper uses remote sensing data and methods to characterize land cover change in four sites in the lowland Peruvian Amazon over a period of three decades (1987-2017). Multi-village landscapes were purposefully selected to include road accessible sites and others only accessible by river. Landscape analysis focused on buffers around the selected villages used to approximate the areas of influence of farmers in these communities. Deforestation in the Peruvian Amazon has been commonly attributed to agriculture expansion by smallholders. This belief falls short in acknowledging that the contribution of smallholder deforestation is mediated by others decisions around infrastructure development. In this analysis, road connected landscapes experienced greater loss of closed-canopy forest while closed canopy forest remained mostly stable in the river sites over the thirty year study period. Results indicated that closed canopy forest loss occurred in parallel with agricultural expansion at the road sites. The findings contribute to a more nuanced understanding of local land use dynamics and the role of regional infrastructure development as a driver of forest loss.
Gender, labor migration and changes in small-scale farming on Vietnam’s north-central coast
Drawing on the narratives of women and men who have domestic or international migration experiences, this study explores the gendered impacts of migration on small-scale farming in rural Ha Tinh province in Vietnam. The paper investigates men’s and women’s migration experiences, their influence on agricultural production, and impact on their livelihoods after migration. The findings show that households use various strategies to sustain agricultural production in the absence of some members. Women’s increased economic independence through labor migration has not necessarily lead to their increased management roles in agriculture, but they are increasingly challenging stereotypical images of rural women. While migration can be a catalyst for men to transform their livelihoods, it can also widen gaps in social and economic statuses among men.
Can rural outmigration improve household food security? Empirical evidence from Ethiopia
Food insecurity in Ethiopia is a persistent development challenge. In this paper, we investigate the effects of rural outmigration on indicators of household food security in Ethiopia. The empirical data come from a two-year panel data collected from three regions of the country. To control for the potential endogeneity of migration and migration selection bias, our estimation uses a combination of a difference-in-difference (DID) model and an inverse-probability of treatment weighting (IPTW) approach (IPTW-DID). We find that, on average, rural outmigration has significantly improved the amount of daily calories consumed per adult equivalent by around 22%. Our estimation results also show that outmigration has significantly reduced food poverty gap and severity of food poverty by seven and four percentage points, respectively.
Framework Landscape Approach in Displacement Settings: Review and concept
Targeting sustainable development and resilience at the landscape level is increasingly recognized as a viable way to overcome sectoral gaps and find solutions through dialogue with actors at multiple levels. The potential of landscape approaches to address competing claims from a myriad of actors, seems particularly relevant in refugee-hosting landscapes. This document presents results of a review of landscape approaches in displacement settings. The concept framework guided subsequent steps of developing Guidelines for a Landscape Approach in Displacement Settings (GLADS).
