Urban development and species invasion are two major global threats to biodiversity. These threats often co-occur, as developed areas are more prone to species invasion. However, few empirical studies have tested if both factors affect biodiversity in similar ways. Here we study the individual and combined effects of urban development and plant invasion on the composition of arthropod communities.

Drawing on a wide variety of international scientific and technical assessments and policy reports, this comprehensive study depicts the linkages - both physical and biochemical - between important environmental issues.
It also discusses how interlinked, global environmental issues can be confronted in an integrated manner and how such issues influence our ability to meet basic human needs. See also trends, causes, social and economic consequences, technologies, policies and measures to mitigate desertification and land degradation.

The report, “Forests, Trees and the Eradication of Poverty: Potential and Limitations,” shows that forests and trees support human well-being and are critical to end poverty. It finds that forest-poverty dynamics are affected by a range of social, economic, political, and environmental context factors, such as rural outmigration, gender norms, remittance flows, and elite capture. The report’s key messages are highlighted below. Forests and trees can help the poor face global changes such as climate change. Benefits from forests and trees to human well-being are unevenly distributed.

Land degradation is a pervasive, systemic phenomenon: it occurs in all parts of the terrestrial world and can take many forms. Combating land degradation and restoring degraded land is an urgent priority to protect the biodiversity and ecosystem services vital to all life on Earth and to ensure human well-being

The pressure on land is growing in many regions of the world, due to the increasing demand for arable crops, meat and dairy products, bio-energy and timber, and is exacerbated by land degradation and climate change. This policy report provides scenario projections for the UNCCD Global Land Outlook, exploring future changes to the use and condition of land and the resulting impacts on food, water, climate change and biodiversity.

This paper explores the role of the global food system as the principal driver of accelerating biodiversity loss. It explains how food production is degrading or destroying natural habitats and contributing to species extinction. The paper outlines the challenges and trade-offs involved in redesigning food systems to restore biodiversity and/or prevent further biodiversity loss, and presents recommendations for action. The paper introduces three ‘levers’ for reducing pressures on land and creating a more sustainable food system.

This publication is intended to raise awareness amongst all stakeholders and galvanise wider action to boost drylands conservation and development. The book is designed to inform and remind us of the beauty of dryland biodiversity and its intrinsic and instrumental value. It demonstrates the mutual dependency of dryland biological and cultural diversity. The book includes new analyses of drylands biodiversity and an overview of approaches that promote sustainable development as well as conservation goals.

Land degradation is a pervasive, systemic phenomenon: it occurs in all parts of the terrestrial world and can take many forms. Combating land degradation and restoring degraded land is an urgent priority to protect the biodiversity and ecosystem services vital to all life on Earth and to ensure human well-being

When the UN Convention to Combat Desertification was created at the Rio Earth Summit over 25 years ago, it became the only international convention dedicated to protecting, managing and restoring our land. The environmental benefits of that work are already well documented, particularly when it comes to the inextricablelinks with climate change and biodiversity. But this book goes much further by highlighting the impact on the wellbeing of over three billion people – nearly half the world’s population – who are directly affected by land degradation.

You cannot put a price tag on nature — but the economic numbers point to its protection,” said Anthony Waldron, the lead author of the report and researcher focused on conservation finance, global species loss and sustainable agriculture.

Facts and Figures: ➡ Every minute, 23 hectares of arable land are lost due to drought and desertification. ➡ Over the last two decades, approximately 20 per cent of the Earth’s vegetated surface has shown persistent declining trends in productivity, mainly due to unsustainable land and water use and management practices. ➡ Every year, 13 million hectares of forest are lost that are home to more than 80 per cent of all land-based species and which provide livelihood to 1.6 billion people.

Humanity at a crossroads
Global Biodiversity Outlook (GBO) is the flagship publication of the Convention on Biological Diversity (CBD). It is a periodic report that summarizes the latest data on the status and trends of biodiversity and draws conclusions relevant to the further implementation of the Convention.
