5 pages, The scientific advice needed to inform national and regional policies addressing the key challenges we face today must take account of disparate requirements. The complex nature of the problems addressed in this article—which encompass food and nutrition security, global health and climate change—and the multitude of their interconnections, calls for an integrated and multi-disciplinary approach that spans aspects related to the use of natural resources; the adoption of new technologies all the way to issues related to food demand and human behaviour. The scale is also important: national policies need to respond to a set of heterogeneous local conditions and requirements and should be particularly mindful of the effect on vulnerable groups of the population. At the same time, the global interconnectedness of food systems and shared natural resources also necessitates coordinated action at regional and global levels. The InterAcademy Partnership sought to develop an innovative model for integrating and analysing multidisciplinary scientific evidence to inform governments and regional policy bodies for policymaking on food and nutrition security. This approach relies on IAP’s membership of over 130 science academies grouped in four regional networks for Africa, America, Asia and Europe. Our article reviews the model, in particular with regards to interdisciplinarity, exploring examples relating to yield gap, plant breeding and food processing, and reflects on lessons learned during the project discussions and when engaging with policy-makers and other stakeholders. We propose that the framework developed can be applied to integrated assessment of other societal challenges where the scientific community can play a significant role in informing policy choices.
20 pages, One of the main drivers of food insecurity is pests, which are estimated to cause around 40% of crop losses worldwide. We examine the food security effects of plant clinics, a novel agricultural extension model that aims to reduce crop losses due to pests through the provision of demand-driven plant health diagnostic and advisory services to smallholder farmers. The study is based on survey data from maize-growing households in Rwanda, where 66 plant clinics have been established. Using switching regression and matching techniques as well as various food security metrics, including the food insecurity experience scale, we find evidence that participation in plant clinics is significantly associated with a reduction in household food insecurity. For instance, among the participating households, plant clinics contribute to a decrease in the period of food shortage by one month and a reduction in the severity of food insecurity by 22 percentage points. We also show that these effects are more pronounced for female-headed households. Overall, our findings suggest that plant clinics can play an important role in achieving the Sustainable Development Goal 2 of zero hunger.
19 pages., Authors scanned literature in nine food systems journals to identify and characterize instances of "food waste" and "food loss" mentions. Findings indicated that this topic is growing within food studies but is still a marginal concept. They suggested three potential areas of food systems research to help advance the discourse and progress in reducing food loss and wastage.
https://link-springer-com.proxy2.library.illinois.edu/content/pdf/10.1007/s10708-019-10024-2.pdf, 15 pages, Enhancing sustainable food security requires agricultural production systems to change in the direction of higher productivity and to mitigate lower output variability in the face of climate extreme related hazards such as land degradation. Adoption of resilient food production system capable of withstanding disruptive events is therefore needed to stabilize farmers' productivity. Consequently, participation in collective actions has been touted as an effective approach to enhance cooperation among individuals within a social system and to advance adoption of climate-smart farming techniques (conservation agriculture). This study investigated this perspective using heterogeneous treatment effects estimation to analyze the data collected from 350 smallholder farmers selected randomly from the South–West Nigeria. The average treatment effects on the treated estimate revealed that participation in collective actions had adoption-increasing effect for each unit variation in propensity score rank, although, negative selection effect was suspected. Similarly, information acquisition, access to extension service and frequency of visit by extension workers are significant features that predict adoption in the study area. However, rosenbaum sensitivity analysis test revealed that the increasing effect of participation in collective actions on conservation agriculture adoption is insensitive to unobserved bias that may double or triple the odds of exposure to treatment. Hence, the average treatment effect on the treated estimate is a pure impact of the participation in collective actions. The study concluded that farmers with high propensity to participate in collective action have high likelihood to adopt climate-resilient farming practices compared to the counterparts with a lower propensity of participation in collective action.
