ArticleJournal articleDesertification combating and ecological restoration of selected acacia species from sub-sahara, savanna regions
XV World Forestry Congress, 2-6 May 2022

No results found.The Acacia species are widely distributed in the Sub-Sahara, Savanna regions and are of significant importance in terms of ecological remediation, afforestation programming, and economic value. Seed dormancy is common in Acacia species, and it creates difficulties in seed testing and planting. The initial aim of the current study was to assess the influence of a different temperature and different levels of water potential for germination based on the hydrothermal time models that had been successfully prophesying germination demand in several threat categories. Seeds of four Acacia species were treated at different temperature (15°C, 20°C, 25°C, 30°C and 35°C) and different levels of osmotic stress (0, -.4, -0.8, and -1.2 MPa). The results revealed that the degree of dormancy variation among the species, they were 81% for A. nilotica, 74% for A. seyal, 15% for A. mellifera, and 5% for A. senegal. Whereas, the optimal temperatures responded is 25°C for A. seyal, and A. senegal, A. nilotica, and 20°C for A. mellifera. Therefore, there are negative correlations appeared within germination percentages and water potential, . seyal, and A. senegal was displayed a drought-tolerant significantly lower levels of water stress. In contrast, A. nilotica and A. mellifera indicated less drought-tolerant of promoting water stress.

No results found.The “Action Against Desertification in support of the implementation of the Great Green Wall for the Sahara and the Sahel Initiative, the UNCCD action plans in Fiji and Haiti, and South–South Cooperation in the African, Caribbean and Pacific Group of States” project (AAD) worked with eight countries in Africa, the Caribbean and Asia to tackle the detrimental social, economic and environmental impacts of land degradation and desertification (2014 to 2020). It was implemented by the Food and Agriculture Organization of the United Nations (FAO) and partners, with majority of funding from the European Union and co-funding from diverse partners. The project contributed to improving the conditions and productivity of agrosilvipastoral landscapes and the capacity to plan land restoration and manage forest and land resources. Livelihood improvements and concrete positive incidence on household income, food security, crops and milk production, and community interactions. It increased awareness and support policy makers developing intervention strategies that address D/LDD. The large-scale, heavy machinery-based technical intervention logic was found appropriate to address desertification/land degradation and drought (D/LDD) in specific conditions and countries. The geospatial study estimated the contribution of Action Against Desertification (AAD) to carbon sequestration to be between 384 000 and 1.27 million tonnes of carbon sequestered. The evaluation recommendations include further investments in training; building awareness and addressing climate change and land degradation; increasing political and policy coherence; guaranteeing sustainability and buy-in from beneficiaries; building in sustainable financing mechanisms at all stakeholder levels; increasing opportunities; and developing non-timber forest product (NTFP) value chains to create and develop viable markets for the products. -

Book (stand-alone)Corporate general interestPulses: nutritious seeds for a sustainable future 2016
The aim of raising global awareness on the multitude of benefits of pulses was integral to the International Year of Pulses. This coffee table book is part guide and part cookbook— informative without being technical. The book begins by giving an overview of pulses, and explains why they are an important food for the future. It also has more than 30 recipes prepared by some of the most prestigious chefs in the world and is peppered with infographics. Part I gives an overview of pulses and giv es a brief guide to the main varieties in the world. Part II explains step-by-step how to cook them, what to keep in mind and what condiments and instruments to use. Part III underscores the five messages that FAO conveys to the world about the impact pulses have on nutrition, health, climate change, biodiversity and food security. Part IV illustrates how pulses can be grown in a garden patch with easy gardening instructions and how they are grown in the world, highlighting major world producers , importers and exporters. Part V takes the reader on a journey around the world showing how pulses fit a region’s history and culture and visits 10 internationally acclaimed chefs as they go the market to buy pulses. Back at their restaurant or home, each chef prepares easy dishes and gives their best kept secrets. Each chef provides 3 recipes that are beautifully illustrated.

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2020
Transforming food systems for affordable healthy diets
2020Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions.The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic.The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition. -
Book (stand-alone)High-profileState of knowledge of soil biodiversity - Status, challenges and potentialities
Report 2020
2020Also available in:
No results found.There is increasing attention to the importance of biodiversity for food security and nutrition, especially above-ground biodiversity such as plants and animals. However, less attention is being paid to the biodiversity beneath our feet, soil biodiversity, which drives many processes that produce food or purify soil and water. This report is the result of an inclusive process involving more than 300 scientists from around the world under the auspices of the FAO’s Global Soil Partnership and its Intergovernmental Technical Panel on Soils, the Convention on Biological Diversity, the Global Soil Biodiversity Initiative, and the European Commission. It presents concisely the state of knowledge on soil biodiversity, the threats to it, and the solutions that soil biodiversity can provide to problems in different fields. It also represents a valuable contribution to raising awareness of the importance of soil biodiversity and highlighting its role in finding solutions to today's global threats.
