ArticleJournal articleEthnobotanical survey of less-known indigenous edible tree Diospyros mespiliformis (Ebenaceae) in Benin, West Africa
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.African ebony (Diospyros mespiliformis) is a priority indigenous fruit tree that has several uses but its use pattern and conservation are little documented across various ethnic groups in Benin. These surveys carried out in 2018 aimed at provide a critical appraisal of the existing knowledge on the ethno-botanical value of these resources among 317 registered informants. Data on socio demographic characteristics and uses of these plant resources was collected based on oral interview using Kobo Collect tool and a well-structured questionnaire from 11 ethnic groups. Quantitative analysis techniques including Multiple Correspondence Analysis (MCA), Hierarchical Clustering (HCPC) and beta-regression (beta-reg)) were performed to evaluaterelative usefulness of different tree organs and the extent to which quantitative indexes give similar results. Results revealed three clusters with diverse uses of D. mespiliformis. The main uses categories of African ebony were food-fodder, medicinal, construction and magico-religious. The results showed also significant difference in use between ethnic groups, generations and socio-professional categories (P < 0.05). However, gender, religion and educational background of informants were not a determinant of local knowledge (P > 0.05). In addition, diseases treated with D. mespiliformis werefever, dressing wound, malaria and infertility. Our findings suggest that local availability of D. mespiliformis should prioritize the fruit and the wood which are the most valued parts of the plant. In order to fully explore the plant’s potential, this resource needs development of integrated cultivation approach, safety evaluation and detailed ethno-pharmacological studies because it is not excluded that interesting medicinal properties setting in light by research permit to finalize new drug.

ArticleJournal articleA checklist of vascular plants of Ewe-Adakplame Relic Forest in Benin, West Africa
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Covering 560.14 hectares in the south-east of Benin, the Ewe-Adakplame Relic Forest (EARF) is a micro-refugium that shows insular characteristics within the Dahomey Gap. It is probably one of the last rem-nants of tropical rain forest that would have survived the late Holocene dry period. Based on intensive field investigations through 25 plots (10 × 50 m size) and matching of herbarium specimens, a checklist of 185 species of vascular plant belonging to 54 families and 142 genera is presented for this forest. In ad-dition to the name for each taxon, we described the life form following Raunkiaer’s definitions, chorology as well as threats to habitat. The Rubiaceae family was the richest (20 species) followed by the Fabaceae (15 species). Life forms showed the preponderance of phanerophytes (88%). The Chorological spectrum was dominated by Guineo-Congolean species (66%). Species richness estimated were 200.52 ± 9.2808 for Bootstrap; 217.62 ± 14.5972; 224.16 ± 15.3725 and 242.67 respectively for Chao, Jacknife1 and Jacknife2. Bootstrap appears to be the estimation closer to the field records. In Benin, EARF is home for Rinorea species described as West African forest bio-indicators and single location for Nesogordonia papa-verifera, Mansonia altissima, Englerophytum oblanceolatum, Octolobus spectabilis, Vitex micrantha and most of Drypeteae tribe species (Drypetes aframensis, Drypetes afzelii, Drypetes gilgiana and Drypetes leonensis) recorded in Benin. Our results provides baseline information for further in-depth analysis of vegetation history in Benin by raising the question on the past floristic connection of the Dahomey gap and com-munity engagement in conservation.

ArticleJournal articleLand use and land use changes by the farmers from mulberry (Morus alba) plantations to green forest tree based farming for income growth and sustainability in Malda district of India
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Malda district was famous for two economic activities viz. Mango (Mangifera indica) cultivation and rearing mulberry silkworm (Bombyx mori). Earlier silkworm rearing was a flourishing cottage industry and every households of Kaliachak block reared silkworm for cocoon production. It was the major livelihood of rural farmers but they suffered heavily due to cheap import of silk from China. Thus, the backbone of farmers was crippled, hence they started cultivating various trees in mulberry fields along with agricultural crops for sustaining their livelihood. Present study was undertaken to know how farmers adjusted to new situation, their knowledge about trees, income growth and sustainability. It was observed that mulberry was raised as herb and leaves were fed to the silkworm larvae at home. Traditionally farmers planted Dalbergia sissoo trees on the border of mulberry fields but later on they started planting other trees. A few farmers uprooted their mulberry bushes and converted to Swietenia macrophylla plantation. Some farmers converted their entire land to Mango and Litchi chinensis orchards for long term gains. Besides, some traditional farmers, around 10% still continued with silkworm rearing for their livelihood security but planted few rows of trees like Tectona grandis, D.sissoo, Bombax ceiba, S.macrophylla and Acacia auriculiformis. Few big farmers converted their mulberry fields into ponds for fishery, however, planted Mango and Sissoo on border. The first crops inside the tree plantations were Maize, Papaya and Vegetables which gave farmers quick income. Later, Banana and Citrus were planted. These activities are still continuing, but timber harvesting has also started which will give high returns. These forest tree based land changes not only provided sustainable income growth to farmers, but also made them drought resilient leading to climate change mitigation and adaptation besides conserving plant biodiversity.

Moving forward on food loss and waste reduction
2019The need to reduce food loss and waste is firmly embedded in the 2030 Agenda for Sustainable Development. Food loss and waste reduction is considered important for improving food security and nutrition, promoting environmental sustainability and lowering production costs. However, efforts to reduce food loss and waste will only be effective if informed by a solid understanding of the problem. This report provides new estimates of the percentage of the world’s food lost from production up to the retail level. The report also finds a vast diversity in existing estimates of losses, even for the same commodities and for the same stages in the supply chain. Clearly identifying and understanding critical loss points in specific supply chains – where considerable potential exists for reducing food losses – is crucial to deciding on appropriate measures. The report provides some guiding principles for interventions based on the objectives being pursued through food loss and waste reductions, be they in improved economic efficiency, food security and nutrition, or environmental sustainability. -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms.
