ProjectProgramme / project reportStrengthening management to combat threats from Aquatic Invasive Alien Species in Venezuela 2024
Also available in:
No results found.The purpose of this project is to support national efforts to strengthen the institutional framework for the prevention, early detection, control and eradication of Invasive Alien Species (IAS) and Potentially Invasive Alien Species (PIAS), emphasizing those that threaten environments aquatic species, and implement the National Action Plan of the NSCBD 2010-2020, in its strategic Line 5, which recognizes exotic species as one of the direct causes of the loss of biological diversity. -
No Thumbnail AvailableDocumentWorking paperBiosecurity in forestry: A case study on the status of invasive forest tree species in Southern Africa 2003
Also available in:
No results found.Invasive tree species are now considered to be a threat to the biological diversity of Southern Africa. Most of the invasive tree species in Southern Africa were either deliberate or accidental introductions. Most of the invasive tree species are exotic, with only one or two being indigenous. These invasive exotic tree species are causing significant environmental and economic damage to the ecosystems of the region. The documented environmental damage includes: (i) reduction of species richness; (ii) reduction of stream flow; (iii) alteration of the nutrient status of soil, (iv) alteration of the biomass of ecosystems, and (v) changes in fire intensity due to altered fuel load. In South Africa, an estimated 100 739 km2 (8.07 percent of national area) have been affected by invasive alien tree species. -
Book (stand-alone)Technical bookCommon plants of Maldives 2016
Also available in:
No results found.The book includes information on 270 species of vascular plants observed during our surveys conducted in more than 50 islands in Maldives. It deals with the common native as well as all alien plants which are currently occuring in the Islands. Information provided includes the current valid name of the plant, most popular synonyms, names in Dhivehi and a few common English names. Plant descriptions given include data on vegetative characters avoiding confusing scientific terms, as far as possibl e. Data collected from the fi eld are the source of information on the occurrence and pattern of distribution in different islands. Threats and damages caused by invasive alien species are also included. Ethnobotanical information collected during the study is given under uses. However, use of any plant/plant parts for medicinal purposes, based on the information provided in this book, cannot be recommended for want of evidence on the non-toxicity of the plant/ plant parts. So, the readers of th e book are advised to refrain from use of the plant/ plant parts for medicinal purposes. It is hoped that this book will be used as a field guide for identification of native, nonnative and invasive plants of Maldives by specialists and non-specialists alike.

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. -
