From nature-negative to nature-positive production


Book Description

Following the 2021 United Nations Food System Summit call for implementing nature-positive production, this document provides an overview on the conceptual, theoretical and operational aspects of nature-positive production agriculture. The concept of nature-positive production revolves around the possible synergies between ecosystem restoration and food/biomass production and among biodiversity, nature and agriculture. This document tries to answer such questions as “What does nature positive exactly mean?” and “How can agriculture aid in ecosystem restoration?” The thermodynamic perspective is chosen as the privileged viewpoint that allows for a joint analysis from both an ecological and agronomic perspective. This document discusses the inherent functioning of agroecosystems by analysing how ecosystems naturally develop their own sustainability and productivity; it concludes that the most critical systemic features in this regard are complexity, energy storage and energy mobilization capacities. In agroecosystems, these three features are mostly linked with biomass availability, biodiversity, soil health and landscape diversity. The nexus of biodiversity and productivity is therefore uncovered, highlighting the need for a renewed relationship between biodiversity and agriculture. After defining the most relevant theoretical aspects of nature-positive production agriculture, this document provides methodologies for assessing the energy efficiency of an agroecosystem and its agroecological performance. Finally, five priority operational areas are proposed to lead the actual implementation of NPPA: soil and water conservation; soil improvement; evolutionary populations; integrating crops, forestry, livestock and aquaculture; and integrated pest management.




A Framework for Assessing Effects of the Food System


Book Description

How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.




The State of the World's Biodiversity for Food and Agriculture


Book Description

The State of the World's Biodiversity for Food and Agriculture presents the first global assessment of biodiversity for food and agriculture worldwide. Biodiversity for food and agriculture is the diversity of plants, animals and micro-organisms at genetic, species and ecosystem levels, present in and around crop, livestock, forest and aquatic production systems. It is essential to the structure, functions and processes of these systems, to livelihoods and food security, and to the supply of a wide range of ecosystem services. It has been managed or influenced by farmers, livestock keepers, forest dwellers, fish farmers and fisherfolk for hundreds of generations. Prepared through a participatory, country-driven process, the report draws on information from 91 country reports to provide a description of the roles and importance of biodiversity for food and agriculture, the drivers of change affecting it and its current status and trends. It describes the state of efforts to promote the sustainable use and conservation of biodiversity for food and agriculture, including through the development of supporting policies, legal frameworks, institutions and capacities. It concludes with a discussion of needs and challenges in the future management of biodiversity for food and agriculture. The report complements other global assessments prepared under the auspices of the Commission on Genetic Resources for Food and Agriculture, which have focused on the state of genetic resources within particular sectors of food and agriculture.




Renewable Energy and Wildlife Conservation


Book Description

Brings together disparate conversations about wildlife conservation and renewable energy, suggesting ways these two critical fields can work hand in hand. Renewable energy is often termed simply "green energy," but its effects on wildlife and other forms of biodiversity can be quite complex. While capturing renewable resources like wind, solar, and energy from biomass can require more land than fossil fuel production, potentially displacing wildlife habitat, renewable energy infrastructure can also create habitat and promote species health when thoughtfully implemented. The authors of Renewable Energy and Wildlife Conservation argue that in order to achieve a balanced plan for addressing these two crucially important sustainability issues, our actions at the nexus of these fields must be directed by current scientific information related to the ecological effects of renewable energy production. Synthesizing an extensive, rapidly growing base of research and insights from practitioners into a single, comprehensive resource, contributors to this volume • describe processes to generate renewable energy, focusing on the Big Four renewables—wind, bioenergy, solar energy, and hydroelectric power • review the documented effects of renewable energy production on wildlife and wildlife habitats • consider current and future policy directives, suggesting ways industrial-scale renewables production can be developed to minimize harm to wildlife populations • explain recent advances in renewable power technologies • identify urgent research needs at the intersection of renewables and wildlife conservation Relevant to policy makers and industry professionals—many of whom believe renewables are the best path forward as the world seeks to meet its expanding energy needs—and wildlife conservationists—many of whom are alarmed at the rate of renewables-related habitat conversion—this detailed book culminates with a chapter underscoring emerging opportunities in renewable energy ecology.

The natural choice


Book Description

This white paper sets out proposals for a detailed programme of action to repair damage done to the environment in the past, and urges everyone to get involved in helping nature to flourish at all levels - from neighbourhoods to national parks. The plans are directly linked to the groundbreaking research in the National Ecosystem Assessment that showed the strong economic arguments for safeguarding and enhancing the natural environment. They also act on the recommendations of 'Making Space for Nature', a report into the state of England's wildlife sites, led by Professor John Lawton and published in September 2010, which showed that England's wildlife sites are fragmented and not able to respond to the pressures of climate change and other pressures we put on our land. Key measures proposed include: i) Reconnecting nature with New Nature Improvement Areas (NIAs) with a £7.5 million fund for 12 initial NIAs, biodiversity offsetting, New Local Nature Partnerships with £1 million available this year, phasing out peat, ii) Connecting people and nature for better quality of life with Green Areas Designation, better urban green spaces; more children experiencing nature by learning outdoors, strengthening local public health activities, the new environmental volunteering initiative "Muck in 4 Life" to improve places in towns and countryside for people and nature to enjoy and iii) Capturing and improving the value of nature with a Natural Capital Committee; an annual statement of green accounts for UK Plc, a business-led Task Force to expand the UK business opportunities from new products and services which are good for the economy and nature alike.
