This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Northern Great Plains (NGP), the combined impacts of land-use and climate variability have the potential to place many soils on the tipping point of sustainability. The objectives of this study were to assess if the conversion of grassland to croplands occurred on fragile landscapes in the North America Northern Great Plains. South Dakota and Nebraska were selected for this study because they are located in a climate transition zone. We visually classified 43,200 and 38,400 points in South Dakota and Nebraska, respectively, from high-resolution imagery in 2006, 2012, and 2014 into five different categories (cropland, grassland, habitat, NonAg, and water). The sustainability risk of the land-use changes was assessed based on the land capability class (LCC) scores at the selected sites. Sites with LCC scores ,⧠4 are considered sustainable for crop production if appropriate management practices are followed. Scores ,â• 6 are not considered suitable for row crop production. From 2006 to 2014, 910,000 and 360,000¬†ha of land were converted from grassland to cropland in South Dakota and Nebraska, respectively. Approximately 92 and 80% of the grassland conversion to croplands occurred on land suitable for crop production (land capability class, LCC ,⧠4) in South Dakota and Nebraska, respectively.

Book Synopsis The Influence of Human Activities and Soil Properties on Soil Carbon Dynamics in a Diversity of Soils by : Elliot Vaughan
Download or read book The Influence of Human Activities and Soil Properties on Soil Carbon Dynamics in a Diversity of Soils written by Elliot Vaughan and published by . This book was released on 2020 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils represent one of the largest terrestrial reservoirs of carbon (C) and understanding the controls on soil C cycling has important implications for climate change and soil fertility. Large uncertainties remain regarding the relative importance of environmental and edaphic factors, and the role of human activities on soil C dynamics. This is especially true in soils of the tropics, which are diverse and often less studied relative to temperate soils. This dissertation sought to address these uncertainties by looking at the effect of several different anthropogenic global change drivers on soil C across a diversity of soils in Puerto Rico. The effect of long-term experimental nitrogen enrichment on soil C content weakened over time and differed within lowland and montane forests, highlighting heterogeneity in responses at the landscape level. Natural abundance radiocarbon (14C) measurements indicated the dynamic nature of soil C in these forests, as the majority of C cycled on decadal time scales, even in mineral-associated fractions that are thought to be quite stable. In a regional study comparing controls on soil carbon turnover under different land covers across the island, soil properties related to parent material and soil weathering, including iron and aluminum concentrations and pH, had a greater influence on the distribution of C among soil fractions and their turnover rate than land cover and land use. Soil C and nitrogen (N) did not differ within a secondary forest chronosequence along a soil-weathering gradient, but C increased with soil pH. Spectroscopic and microscopic analyses of soil organic matter revealed differences in chemistry in buried soils depending on their exposure to the modern soil surface. This work emphasizes the importance of soil physical and chemical properties in influencing soil C dynamics and highlights the complex nature of interactions among human activities, natural disturbances, and soils in heterogenous landscapes.

Book Synopsis Food, Feed, Fuel, Timber or Carbon Sink? Towards Sustainable Land Use by : Miguel Brandão
Download or read book Food, Feed, Fuel, Timber or Carbon Sink? Towards Sustainable Land Use written by Miguel Brandão and published by Springer Nature. This book was released on 2021-04-15 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a holistic framework for assessing the environmental and economic impacts of land-use strategies for a range of purposes, such as food, animal feed, biomass and biofuels, and timber. Using land for one purpose negates its use for any other competing purpose. Given that it is in limited supply, land needs to be optimised so that it can meet the increasing demand for crops of a growing and wealthier human population, while providing ecosystem services, such as carbon storage (i.e. climate-change mitigation). The framework is quantitative and includes various indirect effects, like indirect land-use change, and is a robust basis with which to assess global impacts from land-use decisions on climate change, ecosystem services and biodiversity.

Book Synopsis Management of Carbon Sequestration in Soil by : Rattan Lal
Download or read book Management of Carbon Sequestration in Soil written by Rattan Lal and published by CRC Press. This book was released on 2019-08-08 with total page 811 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the importance of soil processes in the global carbon cycle.Agricultural activities considered responsible for an increase in CO2 levels in our atmosphere include: deforestation, biomass burning, tillage and intensive cultivation, and drainage of wetlands.However, agriculture can also be a solution to the problem in which carbon can be removed from the atmosphere and permanently sequestered into the soil. Management of Carbon Sequestration in Soil highlights the importance of world soils as a sink for atmospheric carbon and discusses the impact of tillage, conservation reserve programs (CRP), management of grasslands and woodlands, and other soil and crop management and land use practices that lead to carbon sequestration.

In addition, this book deals with modeling the carbon cycle in soil, and with methods of soil carbon determinations.
Book Synopsis Soil Organic Carbon and Feeding the Future by : Rattan Lal
Download or read book Soil Organic Carbon and Feeding the Future written by Rattan Lal and published by CRC Press. This book was released on 2021-12-30 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter (SOM) is a highly reactive constituent of the soil matrix because of its large surface area, high ion exchange capacity, enormous affinity for water due to hygroscopicity, and capacity to form organo-mineral complexes. It is an important source and sink of atmospheric CO2 and other greenhouse gases depending on climate, land use, soil and crop management, and a wide range of abiotic and biotic factors, including the human dimensions of socioeconomic and political factors. Agroecosystems are among important controls of the global carbon cycle with a strong impact on anthropogenic or abrupt climate change. This volume of Advances in Soil Sciences explains pedological processes set-in-motion by increases in SOM content of depleted and degraded soils. It discusses the relationship between SOM content and critical soil quality parameters including aggregation, water retention and transport, aeration and gaseous exchange, and chemical composition of soil air. The book identifies policy options needed to translate science into action for making sustainable management of SOM as a strategy for adaptation to and mitigation of climate change. Features: Relates soil organic matter stock to soil processes, climate parameters, vegetation, landscape attributes Establishes relationships between soil organic matter and land use, species, and climate Identifies land use systems for protecting and restoring soil organic matter stock Links soil organic matter stock with the global carbon cycle for mitigation of climate change Part of the Advances in Soil Sciences series, this volume will appeal to agricultural, environmental, and soil scientists demonstrating the link between soil organic matter stock and provisioning of critical ecosystem services for nature and humans.
Download or read book Ground Breaking written by Philip Mulvey and published by . This book was released on 2021-08 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical solutions for agricultural management, enabling the restoration of landscape, climate and community. Reaching zero emissions alone won't stop the Earth heating up. There's another factor at play, even bigger than rising greenhouse gas levels: agricultural land use, and it is turning the world's bread baskets into deserts. In south west Western Australia, the 'Bunny Fence Experiment', the world's largest study of two contrasting land uses in the same vast region, showed strong evidence that clearing and cropping was the reason why rainfall over the Wheat Belt has dropped 20 per cent in the lifetime of some of us. This book tells of how what farmers do exports heat waves, dust and fire, south and south-eastward in Eastern Australia and north and north-westward in Western America. You'd be forgiven for thinking there ought to be a law against it, but our lawmakers don't even acknowledge that under the air and the plants, there is anything but bedrock. Soil, the depleted carbon sink that still manages to feed us today, might as well be a vacuum in law, but it could be a saviour for our civilisations. Ground Breaking has solutions too: manage land use, sequester carbon in soil, reduce bare ground and increase bush corridors.
Book Synopsis The Global Environmental Benefits of Land Degradation Control on Agricultural Land by : Stefano Pagiola
Download or read book The Global Environmental Benefits of Land Degradation Control on Agricultural Land written by Stefano Pagiola and published by World Bank Publications. This book was released on 1999-01-01 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the global effects of land degradation, but emphasizes other important levels of land degradation: at the field level, it may result in reduced productivity; at the national level, it may cause flooding, and sedimentation; and, at the global level, it can contribute to climate changes, damaging bio-diversity, and international waters. The effects on climate changes are explored, and the report questions the extent to which land degradation on agricultural land, affects climate change. Does it increase emissions of greenhouse gases? Does it affect land's capacity to serve as a carbon sink? Can appropriate management enhance both land's productivity, and its capacity to store carbon? The carbon cycle in soils is analyzed, indicating land degradation is likely to reduce the ability of soils to serve as carbon sink, and release stored carbon into the atmosphere, and, bio-diversity effects are likely to be adverse. Global benefits of land degradation control, include afforestation, to allow increased carbon sequestration, and provide adequate bio-diversity habitats; and, community-based wildlife management, can provide alternatives to some marginal areas. Although integrating global dimensions into land degradation control projects, may reverse the field level, or national problems it is causing, difficulties and constraints will likely contribute to the failure of these projects.
Book Synopsis Combined Effects of Land Use Change and Climate Change on Soil Loss and Water Bablance Variables by : Yashar Makhtoumi
Download or read book Combined Effects of Land Use Change and Climate Change on Soil Loss and Water Bablance Variables written by Yashar Makhtoumi and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in water balance variables such as runoff and evapotranspiration (ET) are essential in planning and management of land and water resources. Two major factors affecting these variables are climate and land use change. There is a need to investigate the combined effects of land use and climate change at local scales. Towards that end, the hydrological processes were modeled using the Soil and Water Assessment Tool (SWAT) to investigate the impacts of climate and land use change in Southeast US (Makhtoumi, Li, Ibeanusi, and Chen, 2020). We integrated land use based on the Shared Socioeconomic Pathways (SSPs) with future climate data (CMIP5) to study the combined effects on hydrological response of Upper Choctawhatchee Watershed (UCW.) Future rainfall and air temperature, for two time periods (2040-2069 and 2070-2099), were obtained using Global Climate Models to provide SWAT with the climatic forcing in order to project water balance variables. The simulation was carried out under two radiative forcing pathways of Representative Concentration Pathways (RCP4.5 and RCP6.0.) Our results indicate that increased imperviousness resulted from urbanization has more impact on runoff than that of projected changes in climate. Impacts on water balance variables (runoff, ET, discharge) differed seasonally. Results showed peak surface runoff experienced changes under both emission scenarios in June up to five times increase. Among the water balance variables, ET as the least dominant pathways for water loss, showed the modest changes with the largest decrease during fall and summer. Projections indicated more frequent extreme behavior regarding precipitation, peak surface runoff, water yield (WY) and ET, during midcentury. Discharge was estimated to increase through the year and the highest changes were expected during summer and fall with 186.3% increase in November under RCP6.0. Relying on rainfall for farming along with reduced agricultural land use (11.8%) and increased urban area (47%) and population growth, would likely make the water use efficiency critical. In our second study, we focused on the combined impact of land use and climate change on soil erosion at local scales. Topsoil loss is a widespread environmental concern causing adverse impacts on natural and human systems. Severe weather accompanied with human activities can exacerbate this issue degrading soil health and consequently accelerating global and regional food insecurity and injustice. Erosion impairs soil physical and chemical properties such as infiltration rate, water holding capacity, loss of nutrients including soil carbon and nitrogen. Although, temporal properties of a rainfall event have meaningful implications for soil erosion, spatial heterogeneity of a rainfall contributes substantially and cannot be overlooked. Therefore, in the third chapter we investigated soil loss using SWAT in Northern Mississippi. First, we built a hydrological model and calibrated it for both flow and sediment discharge. Then we developed land use and climate scenarios. The land use scenarios include farming (soybean and corn) and grazing practices. The climate scenarios comprise of four different precipitation time series, S0 which no concentration is forced, while S1, S2, and S3 have 3%, 6%, and 9% concentration in top four rainy days, respectively. We coupled the land use and climate scenarios and evaluated a small watershed (Hickahala Creek Watershed) in response. We classified the subbasins into different classes of soil loss severity and then determined the hotspots for soil loss at subbasin scale. Our result suggests that the resolution of rainfall data is crucial in studying the soil loss. We found that pasture management by itself can manifold soil loss, and if accompanied with extreme rainfalls, soil loss accelerates impacting different subbasins each time. We found that spatial heterogeneity of extreme rainfalls (ERs) can be more substantial than land use in individual extreme rainfalls; however, over a year, soil moisture and type of the management practices (grazing and farming) could contribute more to soil loss. Soil loss can go as high as 350 (ton/ha/yr) under the ERs. Adding only the management practices can increase erosion 3600%. Under S1 parts of watershed yield more than 150 ton/ha/yr (extremely severe). Under S2 and S3 more soil loss hotspots emerge yielding approximately 200 ton/ha/yr. We found that in the hotspots, up to 10% increase in CI can increase annual soil loss up to 75%. Single ER can generate up to 35% of annual soil loss. Under one ER event hotspot subbasins can lose up to 160 ton/ha/day (subbasin 15). The results reveal that adding grazing and farming (S0) under one ER event can increase soil loss by 95%. 32% and 80% increase in rainfall amount in one ER event can increase soil loss by 94% and 285% respectively. Our results suggested the importance of site-specific managements to mitigate soil loss and all the consequences. It is essential to consider the varying sensitivity of subbasins for the sustainability of agricultural landscapes.
