Biodiversity conservation and agricultural sustainability: towards a new paradigm of ‘ecoagriculture’ landscapes

The dominant late twentieth century model of land use segregated agricultural production from areas managed for biodiversity conservation. This module is no longer adequate in much of the world. The Millennium Ecosystem Assessment confirmed that agriculture has dramatically increased its ecological footprint. Rural communities depend on key components of biodiversity and ecosystem services that are found in non-domestic habitats. Fortunately, agricultural landscapes can be designed and managed to host wild biodiversity of many types, with neutral or even positive effects on agricultural production and livelihoods. Innovative practitioners, scientists and indigenous land managers are adapting, designing and managing diverse types of ‘ecoagriculture’ landscapes to generate positive co-benefits for production, biodiversity and local people. We assess the potentials and limitations for successful conservation of biodiversity in productive agricultural landscapes, the feasibility of making such approaches financially viable, and the organizational, governance and policy frameworks needed to enable ecoagriculture planning and implementation at a globally significant scale. We conclude that effectively conserving wild biodiversity in agricultural landscapes will require increased research, policy coordination and strategic support to agricultural communities and conservationists.

One Hundred Questions of Importance to the Conservation of Global Biological Diversity

We identified 100 scientific questions that, if answered, would have the greatest impact on conservation practice and policy. Representatives from 21 international organizations, regional sections and working groups of the Society for Conservation Biology, and 12 academics, from all continents except Antarctica, compiled 2291 questions of relevance to conservation of biological diversity worldwide. The questions were gathered from 761 individuals through workshops, email requests, and discussions. Voting by email to short-list questions, followed by a 2-day workshop, was used to derive the final list of 100 questions. Most of the final questions were derived through a process of modification and combination as the workshop progressed. The questions are divided into 12 sections: ecosystem functions and services, climate change, technological change, protected areas, ecosystem management and restoration, terrestrial ecosystems, marine ecosystems, freshwater ecosystems, species management, organizational systems and processes, societal context and change, and impacts of conservation interventions. We anticipate that these questions will help identify new directions for researchers and assist funders in directing funds.

The top 100 questions of importance to the future of global agriculture

Despite a significant growth in food production over the past half-century, one of the most important challenges facing society today is how to feed an expected population of some nine billion by the middle of the 20th century. To meet the expected demand for food without significant increases in prices, it has been estimated that we need to produce 70–100 per cent more food, in light of the growing impacts of climate change, concerns over energy security, regional dietary shifts and the Millennium Development target of halving world poverty and hunger by 2015. The goal for the agricultural sector is no longer simply to maximize productivity, but to optimize across a far more complex landscape of production, rural development, environmental, social justice and food consumption outcomes. However, there remain significant challenges to developing national and international policies that support the wide emergence of more sustainable forms of land use and efficient agricultural production. The lack of information flow between scientists, practitioners and policy makers is known to exacerbate the difficulties, despite increased emphasis upon evidence-based policy. In this paper, we seek to improve dialogue and understanding between agricultural research and policy by identifying the 100 most important questions for global agriculture. These have been compiled using a horizon-scanning approach with leading experts and representatives of major agricultural organizations worldwide. The aim is to use sound scientific evidence to inform decision making and guide policy makers in the future direction of agricultural research priorities and policy support. If addressed, we anticipate that these questions will have a significant impact on global agricultural practices worldwide, while improving the synergy between agricultural policy, practice and research. This research forms part of the UK Governments Foresight Global Food and Farming Futures project.

Economics and biological diversity : developing and using economic incentives to conserve biological resources

This important book explains in a clear, concise and very readable exposition, how economic incentives can be applied to creative approaches to conservation which complement development efforts.

Agroforestry and biodiversity conservation - traditional practices, present dynamics, and lessons for the future

The environmental services that agroforestry practices can provide, and especially their potential contribution to the conservation of biodiversity, have only recently attracted wider attention among agroforestry and conservation scientists. This new view is consistent with the ecosystem approach to natural resource management advocated by the Convention on Biological Diversity. This collection of six papers, which is based on a Workshop held in June–July 2004, brings together studies of biodiversity impacts of traditional agroforestry practices from Central and South America, Africa and Asia. The contributions highlight the considerable potential of traditional agroforestry practices to support biodiversity conservation, but also show their limits. These include the importance of sufficient areas of natural habitat and of appropriate hunting regulations for maintaining high levels of biodiversity in agroforestry land use mosaics, as well as the critical role of markets for tree products and of a favourable policy environment for agroforestry land uses. In combination the case studies suggest that maintaining diversity in approaches to management of agroforestry systems, along with a pragmatic, undogmatic view on natural resource management, will provide the widest range of options for adapting to changing land use conditions.

Protected areas for the 21st century: working to provide benefits to society

Since the first national park was created at Yellowstone in the USA in 1872, over 8500 protected areas have been established worldwide. Virtually all countries have seen the wisdom of protecting areas of outstanding importance to society, and such sites now cover over 5% of Earths land surface. However, many of these protected areas exist only on paper, not on the ground. Most are suffering from a combination of threats, including pollution, over-exploitation, encroachment, poaching, and many others. In a period of growing demands on resources and shrinking government budgets, new approaches are required to ensure that protected areas can continue to make their contributions to society. First and foremost, protected areas must be designed and managed in order to provide tangible and intangible benefits to society. This will involve integrating protected areas into larger planning and management frameworks, linking protected areas to biodiversity and climate change, promoting greater financial support for protected areas, and expanding international cooperation in the finance, development and management of protected areas.

Expanding partnerships in conservation

Protected areas around the globe - national parks, wildlife reserves, biosphere reserves - will prosper only if they are supported by the public, the private sector, and the full range of government agencies. Yet such support is unlikely unless society appreciates the importance of protected areas to their own interests, and the protected areas are well-managed and contribute to the national welfare in a cost-effective way. A crucial foundation for success is full cooperation between individuals and institutions. Based on papers presented at the IVth World Congress on National Parks and Protected Areas, Expanding Partnerships in Conservation explores how new and stronger partnerships can be formed between managers of protected areas and other sectors of society. It describes a range of activities currently underway in many parts of the world that are intended to improve conservation efforts at the international, national, and local level. The book will be a valuable resource for anyone involved with establishing new protected areas, improving the management of existing areas, and building more positive relationships with the people who live in and around the protected areas.

The Barometer of Life

A broader taxonomic base to threatened species assessments will enable better conservation and policy decisions. On 11 January 2010, the United Nations inaugurated the International Year of Biodiversity in Berlin. This initiative is timely, because the environmental movement suffers from an imbalance between its sense of urgency and its intensity of activity. Center stage is now occupied by concerns for the physical environment—in particular, climate change, pollution, and depletion of nonrenewable resources. However, if the living world is to be kept in anything approaching a sustainable condition that can adapt to changes, then politicians, government officials, scientists, and the public will need to give biodiversity the urgent attention that they are starting to give to the physical environment.

Lessons from the past: forests and biodiversity

The biodiversity of forested regions today is the result of complex historical interactions among physical, biological, and social forces over time, often heavily influenced by cycles of various sorts. Fire, agriculture technology, and trade have been particularly powerful human influences on forests. Virtually all of our planets forests have been affected by the cultural patterns of human use, and the resulting landscape is an ever-changing mosaic of unmanaged and managed patches of habitat, which vary in size, shape, and arrangement. Because chance factors, human influence and small climatic variation can cause very substantial changes in vegetation, the biodiversity for any given landscape will vary substantially over any significant time period- and no one variant is necessarily more ‘natural’ than the others. This implies that biodiversity conservation efforts may need to give greater attention to ecosystem processes than to ecosystem products. A review of historical evidence shows that past civilizations have tended to over-exploit their forests, and that such abuse of important resources has been a significant factor in the decline of the over-exploiting society. It appears that the best way to maintain biodiversity in forest ecosystems in the late 20th Century is through a combination of strictly protected areas (carefully selected on the basis of clearly defined criteria), multiple-use areas managed by local people, natural forests extensively managed for sustainable yield of logs and other products and services, and forest plantations intensively managed for the wood products needed by society. This diversity of approaches and uses will provide humanity with the widest range of options, the greatest diversity of opportunities, for adapting to the cyclical changes which are certain to continue.
