Biodiversity

This science-based study provides a synthesis of existing knowledge for policymakers on the prospects for a sustainable, inclusive forest-based bioeconomy in Europe, including:
• The importance of forests and the forest-based sector in contributing to a European bioeconomy;
• The assessment of a forest-based bioeconomy in view of innovation and economic, social and environmental sustainability;
• Future issues that may affect the development of a forest-based bioeconomy.

In addition to reporting major trends and patterns observed in global fisheries and aquaculture, this edition of the "State of World's Fisheries and Aquaculture" scans the horizon for new and upcoming areas that need to be considered to manage aquatic resources sustainably into the future, including cooperation through regional fisheries bodies and advances such as blockchain technology.

The 2030 Agenda for Sustainable Development is a commitment made by countries to tackle the complex challenges we face, from ending poverty and hunger and responding to climate change to building resilient communities, achieving inclusive growth and sustainably managing the Earth’s natural resources.
As governments determine how best to commit national efforts to achieve transformational change, The State of the World’s Forests 2018 (SOFO 2018) analyses the role that forests and trees – and the people who use and manage them– can play in helping countries achieve their objectives and bring about a brighter future. It shines a light on the profound interlinkages that exist between forests and many other goals and targets of the 2030 Agenda, enabling policy-makers to strike the right balance in actions, investments and partnerships directed towards food security, poverty alleviation, ecological conservation and, ultimately, to find pathways to sustainable development.

The focus of this report is on harnessing AI systems today, and as they evolve, to create maximum positive impact on urgent environmental challenges. It suggests ways in which AI can help transform traditional sectors and systems to address climate change, deliver food and water security, protect biodiversity and bolster human well-being. This concern is tightly linked with the emerging question of how to ensure that AI does not become harmful to human well-being.

Last year's State of the World’s Plants report focused predominantly on synthesising knowledge of the numbers of different categories of plants: How many vascular plants are currently known to science? How many are threatened with extinction? What is the number of plants with uses? etc. We also looked at the main threats to these plants, including climate change, land- use change, invasive plants, disease and over-exploitation. However, simply knowing how many plants there are and how many are under threat is not enough – what is also needed is an understanding of why some plants are more vulnerable than others. This year, therefore, we have also examined the emerging evidence for the characteristics of plants that appear to make some types less/more resilient to current and future threats.
It is not all doom and gloom, however. In this year’s State of the World’s Plants, we also highlight the rapidly accumulating discoveries and knowledge that provide important sign-posts to the next food crops, medicines, timbers etc. Information is now also emerging on the effectiveness of conservation actions and policies in protecting some of the most important plant species and communities across the globe. While there is still much more to do, these positive outcomes demonstrate that with scientific knowledge and evidence-based global actions, it is possible to conserve the extraordinary diversity of plants on Earth and to build on the unique combination of beauty and science which can together provide some of the solutions for the global challenges facing humanity today.

This study examines the effect of climate variability and climate change on the productivity of Australian cropping farms between 1977–78 and 2014–15. The productivity of Australian cropping farms is heavily affected by climate variability, particularly the occurrence of droughts. While Australian farmers are well accustomed to managing this variability, the emergence of climate change is presenting some new challenges.
This study combines ABARES farm survey data with spatial climate data to estimate the effect of climate conditions (such as, rainfall and temperature) on cropping farm TFP (Total Factor Productivity, i.e the combined productivity of labor and capital). The study then presents climate adjusted productivity estimates with the effects of climate removed. For comparison, similar results are generated for farm wheat yields using the same data sources and methods.

Last year’s Global Risks Report was published at a time of heightened global uncertainty and strengthening popular discontent with the existing political and economic order. The report called for “fundamental reforms to market capitalism” and a rebuilding of solidarity within and between countries. One year on, a global economic recovery is under way, offering new opportunities for progress that should not be squandered: the urgency of facing up to systemic challenges has, if anything, intensified amid proliferating indications of uncertainty, instability and fragility.
Humanity has become remarkably adept at understanding how to mitigate conventional risks that can be relatively easily isolated and managed with standard risk management approaches. But we are much less competent when it comes to dealing with complex risks in the interconnected systems that underpin our world, such as organizations, economies, societies and the environment. There are signs of strain in many of these systems: our accelerating pace of change is testing the absorptive capacities of institutions, communities and individuals. When risk cascades through a complex system, the danger is not of incremental damage but of “runaway collapse” or an abrupt transition to a new, suboptimal status quo.
