Africae MonographsAfter two decades of significant change, Johannesburg has been expanding and undergoing deep restructuring. Today, the city is going through an unprecedented development phase, initiated by new territorial dynamics resulting from urban policies, resident practices and market trends. While Johannesburg aims to become a “World Class African City”, as a part of managing its growth it is essential to offer an accurate image of its strengths and weaknesses. The issue of urban resilience has become central to the discourse on cities and calls for light to be shed on the evolutions that have shaped and continue to shape the city of Johannesburg. In this light, we focus on major urban phenomena including: The spatial evolution of the city where densification is not always synonymous with urbanity; Increasing spatial differentiations according to population and housing; Increasingly fragmented and extensive spatial structuring. In this publication, special attention has been given to the compilation of former and recent data. These data, depending on objective geographic elements, show how “various cities” exist within the city. Overcoming the limitations of the data was the main difficulty. Urban evolutions are rapid, but existing data are difficult to access and are often out of date or localised, as part of unsuitable divisions. Various comments have been written to shed light on the maps and facilitate their reading. The objective of this work is to create a coherent set of maps so as to offer a homogeneous vision of the city and urbanisation processes underlining it.Urban StudiesSouth AfricaJohannesburgurban policiesurban developmenttransport networkSouth AfricaJohannesburgurban policiesurban developmenttransport networkUrban StudiesSouth AfricaJohannesburgurban policiesurban developmenttransport networkLévy Karen1331559FR-FrMaCLEBOOK9910576798503321Small Atlas of Johannesburg3040430UNINA04432nam 2200985z- 450 991055774460332120210501(CKB)5400000000045896(oapen)https://directory.doabooks.org/handle/20.500.12854/68622(oapen)doab68622(EXLCZ)99540000000004589620202105d2020 |y 0engurmn|---annantxtrdacontentcrdamediacrrdacarrierQuantification and Mitigation Strategies to Reduce Greenhouse Gas Emissions from Livestock Production SystemsBasel, SwitzerlandMDPI - Multidisciplinary Digital Publishing Institute20201 online resource (168 p.)3-03928-530-0 3-03928-531-9 Ruminants contribute significantly to human food security. However, the production of ruminants contributes to greenhouse gas (GHG) emissions that are responsible for climate change. GHGs such as methane, carbon dioxide, and nitrous oxide are produced from different processes of ruminant production. Ruminant enteric methane is a substantial component of methane produced by agriculture. This book presents novel and established methods in quantifying and reducing enteric methane emission from ruminants in different production systems. The book covers different types of ruminants including cattle, sheep, and goats. The chapters are contributed by scientists and authors from different parts of the world, demonstrating the importance of this problem and the universal drive for immediate and sustainable solutions. Although, biologically speaking, the production of enteric methane cannot be reduced to zero, high emissions are an indicator of inefficient digestion of feed in the rumen and low utilisation of feed energy. By presenting research that could lead to robust and yet practical quantification methods and mitigation strategies, this book not only contributes to the discourse and new knowledge on the magnitude of the problem but also brings forward potential solutions in different livestock production systems.Biology, life sciencesbicsscResearch and information: generalbicsscTechnology, Engineering, Agriculture, Industrial processesbicsscabatement costagreementbackgrounded cattlecarbon footprintclimate changedairy cowsdairy goat farmingDesmanthusencapsulated nitrateenteric emissionsenvironmentenvironmental modellingessential oilfecal methanogenic communityforage-to-concentrate ratiogenetic evaluationGHG emissionsgoatgreenhouse gasesgrowth performanceheat stressheiferimmunizationinterchangeabilitylaserlegumeslinear programmingmcrA gene sequencing techniquemethanemethane emissionmethane emissionsmicrobial floramitigation optionsMoringa oleiferaNDIRnitrate leachingnitrogen balancenitrous oxidepasture systemsprediction equationreduction strategyrumen fermentationruminant nutritionsulphur hexafluoride tracer techniquesupplementationtea saponinstropical beef cattlevolatile fatty acidsBiology, life sciencesResearch and information: generalTechnology, Engineering, Agriculture, Industrial processesChagunda Mizeckedt1319361Løvendahl PeteredtChagunda MizeckothLøvendahl PeterothBOOK9910557744603321Quantification and Mitigation Strategies to Reduce Greenhouse Gas Emissions from Livestock Production Systems3033826UNINA
