Dryland Forests
by Purabi Bose Han Van DijkThis volume provides new insights and conceptual understandings of the human and gender dimension of vulnerability in relation to the dynamics of tenure reforms in the dryland forests of Asia and Africa. The book analyzes the interaction between biophysical factors such as climate variability (e. g. droughts) with socio-political processes (e. g. new institutions and authority) and gender dimensions at various temporal and spatial scales. The book presents a number of case studies based on empirical research on forest tenure reform and it consequences on forest-dependent people. In particular, it highlights the interaction between legal, policy and institutional reform and the inclusion and/or exclusion of local people from deriving benefits from forest resources in the drylands. The book focuses on the questions how land tenure reform and natural resource governance impacts upon marginal groups (along individual, collective and gender dimensions); how do forest-dependent people prepare for and respond to vulnerability; and what is the effect of forest tenure policy reform on the human rights, gender and citizenship issues in relation to the use and management of forest resources and on conflict in forest zones. These issues are approached from the perspective of marginalized groups (gender and social diversity such as indigenous peoples and herders) in vulnerable dryland forests with a high risk of being exposed to climate variability.
Dryland Horticulture (1 Ser.)
by M. K. Jatav P. L. Saroj B. D. SharmaSustainable livelihood security of resource poor farmers is the top priority for the nation today. However, there is wide gap in productivity of various horticultural commodities among different eco-regions, where horticulture can play significant role particularly in arid and semi arid regions, it is far below than the potential productivity. Hence, sustained and steady growth in rural income is critical for positive impact on living standard of various stakeholders. Therefore, an appropriate strategy needs to be devised for such climatically vulnerable regions. The net income of farmers can surely be increased by efficient management of nutrient, water and agri-input, integrated horticulture based farming system, better market price realization, post harvest management and value addition, integration of secondary enterprises and thereby improving productivity of arid and semi-arid horticultural crops. In this book, several such interventions are given in the form of various chapters which will be of immense use improving the productivity and profitability of horticultural commodities.Note: T&F does not sell or distribute the hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka. This title is co-published with NIPA.

Drylands Facing Change: Interventions, Investments and Identities (Earthscan Studies in Natural Resource Management)
by Angela Kronenburg García, Tobias Haller, Han van Dijk, Cyrus Samimi, Jeroen WarnerThis edited volume examines the changes that arise from the entanglement of global interests and narratives with the local struggles that have always existed in the drylands of Africa, the Middle East, and Central Asia and Inner Asia. Changes in drylands are happening in an overwhelming manner. Climate change, growing political instability, and increasing enclosures of large expanses of often common land are some of the changes with far-reaching consequences for those who make their living in the drylands. At the same time, powerful narratives about the drylands as ‘wastelands’ and their ‘backward’ inhabitants continue to hold sway, legitimizing interventions for development, security and conservation, informing re-emerging frontiers of investment (for agriculture, extraction, infrastructure), and shaping new dryland identities. The chapters in this volume discuss the politics of change triggered by forces as diverse as the global land and resource rush, the expansion of new Information and Communication Technologies, urbanization, the COVID-19 pandemic, and the spread of violent extremism. While recognizing that changes are co-produced by differently positioned actors from within and outside the drylands, this volume presents the dryland’s point of view. It therefore takes the views, experiences, and agencies of dryland dwellers as the point of departure to not only understand the changes that are transforming their lives, livelihoods, and future aspirations, but also to highlight the unexpected spaces of contestation and innovation that have hitherto remained understudied. This edited volume will be of much interest to students, researchers and scholars of natural resource management, land and resource grabbing, political ecology, sustainable development and drylands in general.

Dual-Mode Electro-photonic Silicon Biosensors
by José Juan ColásThis highly interdisciplinary thesis reports on two innovative photonic biosensors that combine multiple simultaneous measurements to provide unique insights into the activity and structure of surface immobilized biological molecules. In addition, it presents a new silicon photonic biosensor that exploits two cascaded resonant sensors to provide two independent measurements of a biological layer immobilized on the surface. By combining these two measurements, it is possible to unambiguously quantify the density and thickness of the molecular layer; here, the approach’s ability to study molecular conformation and conformational changes in real time is demonstrated.The electrophotonic biosensor integrates silicon photonics with electrochemistry into a single technology. This multi-modal biosensor provides a number of unique capabilities that extend the functionality of conventional silicon photonics. For example, by combining the complementary information revealed by simultaneous electrochemical and photonic measurements, it is possible to provide unique insights into on-surface electrochemical processes. Furthermore, the ability to create electrochemical reactions directly on the silicon surface provides a novel approach for engineering the chemical functionality of the photonic sensors. The electrophotonic biosensor thus represents a critical advance towards the development of very high-density photonic sensor arrays for multiplexed diagnostics.
Dual-Polarization Two-Port Fiber-Optic Gyroscope
by Zinan WangThis thesis demonstrates and investigates novel dual-polarization interferometric fiber-optic gyroscope (IFOG) configurations, which utilize optical compensation between two orthogonal polarizations to suppress errors caused by polarization nonreciprocity. Further, it provides a scheme for dual-polarization two-port IFOGs and details their unique benefits. Dual-polarization IFOGs break through the restriction of the "minimal scheme," which conventional IFOGs are based on. These innovative new IFOGs have unique properties: They require no polarizer and have two ports available for signal detection. As such, they open new avenues for IFOGs to achieve lower costs and higher sensitivity.
Dual-Process Theories of Numerical Cognition (SpringerBriefs in Philosophy)
by Mario GrazianoThis book presents a philosophical interpretation to numerical cognition based on dual process theories and heuristics. It shows how investigations in cognitive science can shed light on issues traditionally raised by philosophers of mathematics. The analysis will also help readers to better understand the relationship between current neuroscientific research and the philosophical reflection on mathematics. The author seeks to explain the acquisition of mathematical concepts. To accomplish this, he needs to answer two questions. How can the concepts of approximate numerosity become an object of thought that is so accessible to our consciousness? How are these concepts refined and specified in such a way as to become numbers? Unfortunately, there is currently no model that can truly demonstrate the role of language in the development of numerical skills starting from approximate pre-verbal skills. However, the author details a solution to this problem: dual process theories. It is an approach widely used by theorists focusing on reasoning, decision making, social cognition, and consciousness. Here, he applies this approach to the studies on mathematical knowledge. He details the results brought about by psychological and neuroscientific studies conducted on numerical cognition by key neuroscientists. In the process, he develops the foundations of a new, potential philosophical explanation on mathematical knowledge.
Dualities, Helicity Amplitudes, and Little Conformal Symmetry
by Kitran Macey M. ColwellThis book develops two exciting areas of particle physics research. It applies the recent new insights about the usefulness of helicity amplitudes in understanding gauge theory to the long-standing effort to understand theories with both electric and magnetic charges. It is known that for some supersymmetric theories there is an exact duality that relates two descriptions of the physics, one where the electric charges are weakly coupled and another where the electric charges are strongly coupled. The calculations in this thesis suggest that this duality can also hold in the low-energy limit of nonsupersymmetric gauge theories. The idea of addressing the hierarchy problem of the standard model Higgs mechanism using conformal symmetry is also explored. Analogously to "Little Higgs" models, where divergences are cancelled only at one-loop order, models are studied that have infrared conformal fixed points which related gauge and Yukawa couplings, allowing for a cancellation between seemingly unrelated quantum loop diagrams.

Ducktown Smoke: The Fight Over One of the South's Greatest Environmental Disasters
by Duncan MaysillesIt is hard to make a desert in a place that receives sixty inches of rain each year. But after decades of copper mining, all that remained of the old hardwood forests in the Ducktown Mining District of the southern Appalachian Mountains was a fifty-square mile barren expanse of heavily gullied red hills--a landscape created by sulfur dioxide smoke from copper smelting and destructive logging practices. In Ducktown Smoke, Duncan Maysilles examines this environmental disaster, one of the worst the South has experienced, and its impact on environmental law and Appalachian conservation. Beginning in 1896, the widening destruction wrought in Tennessee, Georgia, and North Carolina by Ducktown copper mining spawned hundreds of private lawsuits, culminating in Georgia v. Tennessee Copper Co. , the U. S. Supreme Court's first air pollution case. In its 1907 decision, the Court recognized for the first time the sovereign right of individual states to protect their natural resources from transborder pollution, a foundational opinion in the formation of American environmental law. Maysilles reveals how the Supreme Court case brought together the disparate forces of agrarian populism, industrial logging, and the forest conservation movement to set a legal precedent that remains relevant in environmental law today.

Dune Worlds
by Ralph D. Lorenz James R. ZimbelmanThis book describes how sand dunes work, why they are the way they are in different settings, and how they are being studied. Particular attention is paid to their formation and appearance elsewhere in the solar system. New developments in knowledge about dunes make for an interesting story - like the dunes themselves, dune science is dynamic - and the visual appeal of Aeolian geomorphology ensures that this is an attractive volume. The book is divided into 4 parts, the first of which introduces dunes as a planetary phenomenon, showing a landscape reflecting the balance of geological processes - volcanism, impact, tectonics, erosion, deposition of sediments. Dunes are then considered as emergent dynamical systems: the interaction of sand and wind conspires to generate very characteristic and reproducible shapes. Analogies are given with other emergent structures such as patterned ground before the influence of dunes on desert peoples and infrastructure is studied, together with their use as forensic climatological indicators. Dune Physics is looked at with regard to the mechanics of sand, the physics of wind, saltation - interaction of sand and air - dunes versus ripples and transverse Aeolian ridges, the classification of dune morphology and the sources and sinks of sand. Dune Trafficability considers soil mechanics, effects on mobility on Earth, Mars and elsewhere. In the second part, Earth, Mars, Titan and other moons and planets are examined, beginning with a survey of the major deserts and dunefields on Earth. The authors then turn to Mars and its environment, sediment type, dune stratigraphy, sediment source and sinks and the association of dunes with topographic features. Titan follows - its thick, cold atmosphere, methane dampness, low gravity, morphology - interaction with topography and the implications of dunes for climate and winds. Dunes elsewhere conclude this part. There are few dunefields on Venus, but there is a . possibility of Aeolian transport on Triton and volcanic-related windstreaks on Io.
