Book excerpt: Research Paper (postgraduate) from the year 2018 in the subject Environmental Sciences, language: English, abstract: When saline water is used to irrigate crops in arid environments, appropriate irrigation management should be applied to avoid negatively impacting soil characteristics. In this study, the effects of irrigating date palms with saline water (2,24 g l-1) on soil physicochemical characteristics such as the electrical conductivity (ECe), the pH of the saturated soil paste (pHe), the concentrations of soluble cations (Ca2+, Mg2+, Na+), the sodium adsorption ratio (SAR), the saturated soil hydraulic conductivity (Ks), and the volumetric water content of the soil (θv) were evaluated in a Tunisian Saharan cropland, the Dergine Oasis, during a 4-year period (2012-2015). The effects of three different irrigation treatments of date palms on soil properties were investigated: low treatment (90% of the net irrigation requirement (NIR) of date palms was applied); medium treatment (100% of NIR was applied), and high treatment (110% of NIR was applied). The results showed that the application of saline water for irrigation inevitably has a negative impact on the physicochemical properties of the soil. Irrigation with saline water was observed to have severe negative impacts on the soil characteristics, especially ECe, Na+, Ks, and θv. However, among the three irrigation treatments applied, statistical analysis (Duncan's multiple range test) indicated that the high treatment significantly (p

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of mine-affected waters contain large quantities of calcium and magnesium sulphate, with some dominated by sodium sulphate or bicarbonate. The availability of large volumes of mine impacted waters and large tracts of unfarmed land owned by mines, creates an opportunity to utilise these waters for irrigation. Not only will this drastically reduce mine water treatment costs, it will create sustainable livelihoods and food production, particularly post-mine closure. The aims of this study were to monitor and model field scale water and salt balances for a small scale mine water irrigation scheme in Mpumalanga, in order to predict the long-term impact and sustainability of gypsiferous mine water irrigation, as well as determining the effect of sulphate salinity on crop response of various temperate annual cereal grain crops. A field trial was established at Mafube Colliery outside Middelburg (Mpumalanga, South Africa) during 2016-2018. White maize was irrigated for one of the two seasons on virgin, unmined land. Regular monitoring was carried out to collect atmospheric, crop and soil data for detailed validation of the soil water balance (SWB) model. For the first season, it has shown that crops (specifically maize) grow well with these mine impacted waters, with minimal environmental impacts in the short term and proved to be more profitable than dryland production. The grain produced is safe for human consumption, which makes this a feasible practice. Pot trials were carried out at the UP Experimental Farm where crops were grown in water culture at five levels of salinity with an EC range of 120 to 2000 mS m-1. A combination of a nutrient solution, gypsum (CaSO4.2H2O) and Epsom salts (MgSO4.7H2O) was used to make up each treatment. The effect of salinity on germination, seedling establishment and vegetative growth was investigated. Increasing sulphate salinity negatively affects germination, seedling and vegetative growth of annual temperate crops, especially when dominated by Mg. After exceeding the threshold for salt stress, a linear reduction in relative growth was found for both seedling establishment and vegetative growth, as well as a decline in germination percentage. In general, annual temperate cereal crops are more sensitive to sulphate salinity during the vegetative growth stage compared to the seedling stage at the same sulphate salinity concentrations. Irrigation with mine water is viable, sustainable and feasible, if the appropriate management practices are in place and if some environmental impact is acceptable. Crop and cultivar selection, climatic conditions, irrigation method, soil and water quality are but a few of the parameters that need to be considered when irrigating with saline sulphate waters. Another important aspect to look at it, is nutritional requirements and possible imbalances.

This book was released on 2018-11-28 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

This book was released on 2014-03-26 with total page 922 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is an irreplaceable resource that sustains life on the planet, challenged by food and energy demands of an increasing population. Therefore, soil contamination constitutes a critical issue to be addressed if we are to secure the life quality of present and future generations. Integrated efforts from researchers and policy makers are required to develop sound risk assessment procedures, remediation strategies and sustainable soil management policies. Environmental Risk Assessment of Soil Contamination provides a wide depiction of current research in soil contamination and risk assessment, encompassing reviews and case studies on soil pollution by heavy metals and organic pollutants. The book introduces several innovative approaches for soil remediation and risk assessment, including advances in phytoremediation and implementation of metabolomics in soil sciences.

This book was released on 2016-08-29 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a unique synthesis of concepts and tools to examine natural resource, socio-economic, legal, policy and institutional issues that are important for managing urban growth into the future. The book will particularly help the reader to understand the current issues and challenges and develop strategies and practices to cope with future pressures of urbanisation and peri-urban land, water and energy use challenges. In particular, the book will help the reader to discover underlying principles for the planning of future cities and peri-urban regions in relation to: (i) Balanced urban development policies and institutions for future cities; (ii) Understanding the effects of land use change, population increase, and water demand on the liveability of cities; (iii) Long-term planning needs and transdisciplinary approaches to ensure the secured future for generations ahead; and (iv) Strategies to adapt the cities and land, water and energy uses for viable and liveable cities. There are growing concerns about water, food security and sustainability with increased urbanisation worldwide. For cities to be liveable and sustainable into the future there is a need to maintain the natural resource base and the ecosystem services in the peri-urban areas surrounding cities. This need is increasing under the looming spectre of global warming and climate change. This book will be of interest to policy makers, urban planners, researchers, post-graduate students in urban planning, environmental and water resources management, and managers in municipal councils.
