This book was released on 2015 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impacts of intensive agriculture on underlying groundwater ecosystems are not yet fully understood, although agricultural practices are firmly implicated in the modification of stygofauna (invertebrate) and microbial populations in aquifers, primarily through changes in water quality associated with irrigated agriculture. The aim of this study was to determine how biological communities in groundwater vary with agricultural land use, and along environmental gradients. Biological and environmental samples were collected from groundwater under irrigated agricultural landscapes and pasture in the Condamine Catchment (QLD), and Gwydir Catchment (NSW). Bacterial populations were evaluated through the analysis of high-throughput 16S rDNA sequence data. The findings of this study did not support the hypothesis that stygofauna distributions vary with agricultural land-use. Molecular data did not support a relationship between microbial distributions and agricultural land-use. Microbial assemblages became more dissimilar with increasing geographic distance. Microbial and stygofauna distributions were poorly correlated with groundwater chemistry gradients. In summary, the influence of agriculture on stygofauna community structure is likey to be limited, since their distributions in the landscape are largely defined by physical limitations of the alluvial aquifer environment. In contrast, the influence of agricultural land-use on groundwater quality is likely to have a quantifiable bearing on microbial distributions, although evidence to support this hypothesis was not forthcoming from the environmental and molecular analysis here. To assess the hypothesis that microbial communities differ with agricultural land-use, further studies should use a metagenomic sequencing approach to estimate the relative abundance of microbes between sites.

Download or read book Climate Change Resilient Agriculture and Agroforestry written by Paula Castro and published by Springer. This book was released on 2019-01-24 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collects wide-ranging contributions such as case studies, reviews, reports on technological developments, outputs of research/studies, and examples of successful projects, presenting current knowledge and raising awareness to help the agriculture and forestry sectors find solutions for mitigating climate variability and adapting to change. It brings the topic of ecosystem services closer to education and learning, as targeted by the Framework Convention on Climate Change and the Paris Agreement, the 2030 Agenda for Sustainable Development and the EU Biodiversity Strategy to 2020. Climate change and its impacts on agriculture and agroforestry have been observed across the world during the last 50 years. Increasing temperatures, droughts, biotic stresses and the impacts of extreme events have continuously decreased agroforestry systems’ resilience to the effects of climate change. As such, there is a need to adapt farming and agroforestry systems so as to make them better able to handle ever-changing climate conditions, and to preserve habitats and ecosystems services.

Download or read book Sustainable Groundwater Management written by Jean-Daniel Rinaudo and published by Springer Nature. This book was released on 2020-03-16 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes and analyses the diversity of possible approaches and policy pathways to implement sustainable groundwater development, based on a comparative analysis of numerous quantitative management case studies from France and Australia. This unique book brings together water professionals and academics involved for several decades in groundwater policy making, planning or operational management to reflect on their experience with developing and implementing groundwater management policy. The data and analysis presented accordingly makes a significant contribution to the empirical water management literature by providing novel, real world insights unpublished elsewhere. The originality of the contributions also lies in the different disciplinary perspectives (hydrogeology, economics, planning and social sciences in particular) adopted in many chapters. The book offers a unique comparative analysis of France, Australia and experiences in countries such as Chile and the US to identify similarities, but also fundamental differences, which are analysed and presented as alternative policy options – these differences being mainly related to the role of the state, the community and market mechanisms in groundwater management.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a profound geographical description and analysis of Central Asia. The authors take a synthetic approach in a period of critical transformation in the post-soviet time. The monograph analyzes comprehensively the physical and human geography as well as human-nature interactions of Central Asia with focus on Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan and Tajikistan. Natural processes are described at a systemic scale, focusing on ecological impacts and consequences and contemporary human adaptations and organization. It also discusses in which ways the human organizations try to apply solutions for their needs such as security, territorial management and resources renewability, material and functional needs, identity elaborations, culture and communication. The Geography of Central Asia appeals to scientists and students of regional geography and interested academics from other areas such as social, political, economic and environmental studies within the context of Central Asia. The book is also a very useful resource for field trips into this area.
Download or read book The California Nitrogen Assessment written by Thomas P. Tomich and published by Univ of California Press. This book was released on 2016-06-14 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is indispensable to all life on Earth. However, humans now dominate the nitrogen cycle, and nitrogen emissions from human activity have real costs: water and air pollution, climate change, and detrimental effects on human health, biodiversity, and natural habitats. Too little nitrogen limits ecosystem processes, while too much nitrogen transforms ecosystems profoundly. The California Nitrogen Assessment is the first comprehensive account of nitrogen flows, practices, and policies for California, encompassing all nitrogen flows—not just those associated with agriculture—and their impacts on ecosystem services and human wellbeing. How California handles nitrogen issues will be of interest nationally and internationally, and the goal of the assessment is to link science with action and to produce information that affects both future policy and solutions for addressing nitrogen pollution. This book also provides a model for application of integrated ecosystem assessment methods at regional and state (subnational) levels.

Download or read book Integrated Groundwater Management written by Anthony J Jakeman and published by Springer. This book was released on 2016-08-05 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.
