Download or read book Interactive Feedbacks between Soil Fauna and Soil Processes written by Maria Luz Cayuela and published by Frontiers Media SA. This book was released on 2020-03-30 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil fauna plays a significant role at all trophic levels of the soil food web and regulates processes that are crucial for soil functioning, such as nutrient cycling, immobilization and/or degradation of toxic compounds, formation of soil structure, greenhouse gas emissions and C turnover. Although soil fauna is not thought to contribute significantly to soil respiration during litter or soil organic matter (SOM) decomposition, the diversity of soil fauna has been found to strongly influence SOM distribution and dynamics. Yet, the functional contribution of soil fauna to many soil processes is not well understood due to methodological limitations and the high complexity of interactions at various spatiotemporal scales. In general, soil fauna has received far less scientific attention than bacteria and fungi (and lately archaea) in soil studies and has been regularly ignored in global biogeochemical models, with maybe exceptions for some earthworms. However, recent studies are raising the awareness of the influence of soil fauna on ecosystems dynamics. For instance, earthworms have been found to be major players in N2O emissions from soils. They exert a strong influence on C stabilization, and they promote the degradation of polycyclic aromatic hydrocarbons (PAHs). Less studied, ants and termites have been found to increase crop productivity in drylands, and different lifeforms of Collembola have been shown to impact microorganisms in various ways over time, thereby potentially affecting C and N cycles within farming systems. The influence of soil fauna indeed manifests over a broad ranges of spatiotemporal scales. For example, some effect such as aggregate formation may cumulate over time and finally contribute to the formation of whole soil profiles, which serve as a framework for other soil processes such as water movement, decomposition, etc. Meanwhile, soil biodiversity is impacted by an increasing human pressure through deforestation, agriculture intensification, habitat fragmentation or climate change (increasing temperatures, extreme weather events), which leads to soil biodiversity loss, in particular of soil fauna, with associated consequences on soil functioning and resilience.

Download or read book Forest and Rangeland Soils of the United States Under Changing Conditions written by Richard V. Pouyat and published by Springer Nature. This book was released on 2020-09-02 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book synthesizes leading-edge science and management information about forest and rangeland soils of the United States. It offers ways to better understand changing conditions and their impacts on soils, and explores directions that positively affect the future of forest and rangeland soil health. This book outlines soil processes and identifies the research needed to manage forest and rangeland soils in the United States. Chapters give an overview of the state of forest and rangeland soils research in the Nation, including multi-decadal programs (chapter 1), then summarizes various human-caused and natural impacts and their effects on soil carbon, hydrology, biogeochemistry, and biological diversity (chapters 2–5). Other chapters look at the effects of changing conditions on forest soils in wetland and urban settings (chapters 6–7). Impacts include: climate change, severe wildfires, invasive species, pests and diseases, pollution, and land use change. Chapter 8 considers approaches to maintaining or regaining forest and rangeland soil health in the face of these varied impacts. Mapping, monitoring, and data sharing are discussed in chapter 9 as ways to leverage scientific and human resources to address soil health at scales from the landscape to the individual parcel (monitoring networks, data sharing Web sites, and educational soils-centered programs are tabulated in appendix B). Chapter 10 highlights opportunities for deepening our understanding of soils and for sustaining long-term ecosystem health and appendix C summarizes research needs. Nine regional summaries (appendix A) offer a more detailed look at forest and rangeland soils in the United States and its Affiliates.
Download or read book Global Soil Biodiversity Atlas written by European Commission. Joint Research Centre and published by . This book was released on 2016 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Atlas describes soil as habitat for the diversity of organisms that live under our feet. At the same time, it draws attention to the threats to soil biodiversity, such as invasive species, pollution, intensive land use practices or climate change. The Atlas provides current solutions for a sustainable management of soils. It was coordinated by the JRC and the Global Soil Biodiversity Initiative (www.globalsoilbiodiversity.org) with more than 70 contributing organisations and several hundred individual contributions. It illustrates the diversity of soil organisms, explains their geographical and temporal distribution, the ecosystem functions and services provided by soil biota. Most importantly, it draws attention to the myriad of threats to soil biodiversity. These include inappropriate land management practices (e.g. deforestation, land take for infrastructure development), agricultural systems, over-grazing, forest fires and poor water management (both irrigation and drainage). Other practices such as land conversion from grassland or forest to cropped land result in rapid loss of soil carbon, which indirectly enhances global warming. The Atlas shows that mismanaging soils could exacerbate the effects of climate change, jeopardise agricultural production, compromise the quality of ground water and worsen pollution. It also proposes solutions to safeguard soil biodiversity through the development of policies that directly or indirectly target soil health, leading to a more sustainable use."--

Download or read book Impact of Agricultural Practices on Biodiversity of Soil Invertebrates written by Stefano Bocchi and published by MDPI. This book was released on 2021-01-06 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil fauna plays a key role in many soil functions, such as organic matter decomposition, humus formation, and nutrient release, modifying soil structure, and improving its fertility. Soil invertebrates play key roles in determining soil suitability for agricultural production and realizing sustainable farming systems. They include an enormous diversity of arthropods, nematodes, and earthworms. However, this fauna suffers from the impact of agricultural activities with implications for the capacity of soil to maintain its fertility and provide ecosystem services. Some agricultural practices may create crucial soil habitat changes, with consequences for invertebrate biodiversity. In the few last decades, especially under intensive and specialized farming systems, a loss in soil ecosystem services has been observed, as a result of the reduction in both the abundance and taxonomic diversity of soil faunal communities. On the other hand, agricultural practices, based on sustainable soil management, can promote useful soil fauna. Therefore, the concerns about the sensibility of soil biota to the agricultural practices make it urgent to develop sustainable management strategies, able to realize favorable microclimate and habitats, and reduce the soil disturbance.

Download or read book Sustainable Living with Environmental Risks written by Nobuhiro Kaneko and published by Springer. This book was released on 2014-03-11 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are not free from environmental risks that accompany the development of human societies. Modern economic development has accelerated environmental pollution, caused loss of natural habitats, and modified landscapes. These environmental changes have impacted natural systems: water and heat circulation, nutrient cycling, and biodiversity. These changes in natural systems degrade ecosystem services and subsequently increase environmental risks for humans. Environmental risks, therefore, are not only human health risks by pollution, climatic anomalies and natural disasters, but also degradation of ecosystem services on which most people are relying for their lives. We cannot entirely eliminate the risks, because it is not possible to attain zero impact on the environment, but we need to find a mechanism that minimizes environmental risks for human sustainably. This is the idea of the interdisciplinary framework of “environmental risk management” theory, which advocates harmony between economic development and environmental conservation. Based on this theory, the Sustainable Living with Environmental Risk (SLER) programme, adopted by the Japanese Ministry of Education (MEXT) as one of its strategic programmes, has been training graduate students at the Yokohama National University, Japan, from 2009 to 2013 to become future environmental leaders who will take the initiative in reducing the level of environmental risks and in protecting natural resources in the developing nations of Asia and Africa. This book provides students and teachers of this new academic field with a comprehensive coverage of case studies of environmental risks and their practical management technologies not only in Japan but also in developing nations in Asia and Africa.
