Dietary contribution of wild edible plants to women's diets in the buffer zone around the Lama forest, Benin - an underutilized potential

Rural populations in developing countries face food insecurity and malnutrition despite being surrounded by extraordinary biodiversity. The international community increasingly recognizes the role of agro-biodiversity and Wild Edible Plants (WEPs) in their contributions to managing risk and building resilience and sustainable food systems. Studies on real contributions of WEPs to peoples’ diets, however, are uncommon. This study assessed the contribution of WEPs to diets of women living in the buffer zone of the Lama forest in southern Benin. During the long dry season, a cross-sectional survey was carried out on 120 women, covering their knowledge and attitudes towards WEPs and two non-consecutive 24-h recalls of their WEP consumption. Contribution of WEPs to total dietary intake was low due to infrequent use and small portion sizes. The highest nutrient contributions of WEPs measured were for copper (13.9 %) and iron (4.6 %) but the majority of the women had intake values below the Estimated Average Requirements (EARs) for these elements - copper 65 % and iron 91 % Women’s dietary diversity was significantly higher among WEP consumers than non-consumers, mainly due to higher consumption of dark green leafy vegetables. WEPs were less consumed as a replacement for other foods but rather as a complement to the diet. The study population generally appreciated WEPs, while some constraints were reported regarding preparation, conservation and commercialization. Before widely promoting WEP consumption in order to exploit their dietary potential, additional investigations are needed into their nutrient composition, cultural and market value, their sustainable harvest levels and possible integration into innovative farming systems

Community-based development of agricultural activities aiming to improve dietary diversity in Western Kenya

This research examines the suitability of community-based participatory workshops for developing agricultural activities in order to diversify diets. The study represents the second phase of a project consisting of a diagnostic phase covering agricultural biodiversity, diets and nutrition (phase I), participatory development of community activities (phase II) and a participatory implementation of the activities (phase III). The project is part of the nutrition cross-cutting cluster work within Humidtropics, a CGIAR research programme (CRP). A series of six participatory workshops was carried out in five sub-locations of Vihiga County in Western Kenya. The workshops aimed to raise awareness on nutrition, to discuss the results of the diagnostic phase (phase I) and to identify and plan community activities to improve nutrition. Per sub-location, 36 men and women were selected to participate in the workshops. In order to diversify diets in their communities, all sub-locations decided to plant ve- getables and legumes and to raise poultry. The participants developed community action plans specifying how these activities are going to be realised. In addition, they chose local funding mechanisms to finance the actions and developed a budget. The groups also suc- ceeded in organising an event to officially kick-off their activities and thereby reaching out to other community members. Except for one less successful sub-location, the workshop groups well developed agricul- tural activities for improved nutrition. Harmony within the group was a crucial factor for good performance. Sensitivity to group dynamics is thus very important for participatory development of community activities. It was observed that the continuous workshops built trust between researchers and participants and that ownership was developed among the groups. These findings are in line with similar studies on participatory intervention deve- lopment in Africa. Other related projects in low-income countries stress the importance of community-based approaches in improving nutrition and livelihood outcome

Early Seizure Detection with an Energy-Efficient Convolutional Neural Network on an Implantable Microcontroller

Implantable, closed-loop devices for automated early detection and stimulation of epileptic seizures are promising treatment options for patients with severe epilepsy that cannot be treated with traditional means. Most approaches for early seizure detection in the literature are, however, not optimized for implementation on ultra-low power microcontrollers required for long-term implantation. In this paper we present a convolutional neural network for the early detection of seizures from intracranial EEG signals, designed specifically for this purpose. In addition, we investigate approximations to comply with hardware limits while preserving accuracy. We compare our approach to three previously proposed convolutional neural networks and a feature-based SVM classifier with respect to detection accuracy, latency and computational needs. Evaluation is based on a comprehensive database with long-term EEG recordings. The proposed method outperforms the other detectors with a median sensitivity of 0.96, false detection rate of 10.1 per hour and median detection delay of 3.7 seconds, while being the only approach suited to be realized on a low power microcontroller due to its parsimonious use of computational and memory resources.Comment: Accepted at IJCNN 201
