Book Description
Grassland: Quietness and Strength for a New American Agriculture takes on the task of increasing our awareness of the vital role grass and grassland plants have in ensuring a sustainable future for America. Geared toward agriculturists, students, the public, and policymakers, Grassland aims to inspire and provide the reader the foundation needed to move into the future. Three main sections * track the history of grassland farming, highlighting the voices of grassland advocates * examine the current roles that grassland plays throughout the United States * look at the benefits grass-based agriculture can provide when grass is treated as an essential resource As Wendell Berry so eloquently argues in the foreword to Grassland, True farmers have minds that are complex and responsible...They understand and honor their debts to nature. They understand and honor their obligations to neighbors and consumers...In the time that is coming, we are going to need many more such farmers than we have, and we will need them much sooner than we can expect to get them.We will get them only to the extent that young people come along who are willing to fit their farming to the nature of their farms and their home landscapes, and who recognize the paramount importance of grass and grazing animals to good farming everywhere. This book will help that happen.
Landscapes of Fraud

Book Description
From the actions of Europeans in the seventeenth century to the real estate deals of the modern era, people making a living off the land in southern Arizona have been repeatedly robbed of their way of life. History has recorded more than three centuries of speculative failures that never amounted to much but left dispossessed people in their wake. This book seeks to excavate those failures, to examine the new social spaces the schemers struggled to create and the existing social spaces they destroyed. Landscapes of Fraud explores how the penetration of the evolving capitalist world-system created and destroyed communities in the Upper Santa Cruz Valley of Arizona from the late 1600s to the 1970s. Thomas Sheridan has melded history, anthropology, and critical geography to create a penetrating view of greed and power and their lasting effect on those left powerless. Sheridan first examines how O’odham culture was fragmented by the arrival of the Spanish, telling how autonomous communities moving across landscapes in seasonal rounds were reduced to a mission world of subordination. Sheridan then considers the fate of the Tumacácori grant and Baca Float No. 3, another land grant. He tells the unbroken story of land fraud from Manuel María Gándara’s purchase of the “abandoned” Tumacácori grant at public auction in 1844 through the bankruptcy of the shady real estate developers who had fraudulently promoted housing projects at Rio Rico during the 1960s and ’70s. As the Upper Santa Cruz Valley underwent a wrenching transition from a landscape of community to a landscape of fraud, the betrayal of the O’odham became complete when land, that most elemental form of human space, was transformed from a communal resource into a commodity bought and sold for its future value. Today, Mission Tumacácori stands as a romantic icon of the past while the landscapes that supported it lay buried under speculative schemes that continue to haunt our history.
Optical Approaches to Capture Plant Dynamics in Time, Space, and Across Scales

Book Description
Quantifying temporal changes in plant geometry as a result of genetic, developmental, or environmental causes is essential to improve our understanding of the structure and function relationships in plants. Over the last decades, optical imaging and remote sensing developed fundamental working tools to monitor and quantify our environment and plants in particular. Increased efficiency of methods lowered the barrier to compare, integrate, and interpret the optically obtained plant data across larger spatial scales and across scales of biological organization. In particular, acquisition speed at high resolutions reached levels that allow capturing the temporal dynamics in plants in three dimensions along with multi-spectral information beyond human visual senses. These advanced imaging capabilities have proven to be essential to detect and focus on analyzing temporal dynamics of plant geometries. The focus of this Research Topic is on optical techniques developed to study geometrical changes at the plant level detected within the wavelength spectrum between near-UV to near infrared. Such techniques typically involve photogrammetric, LiDAR, or imaging spectroscopy approaches but are not exclusively restricted to these. Instruments operating within this range of wavelengths allow capturing a wide range of temporal scales ranging from sub-second to seasonal changes that result from plant development, environmental effects like wind and heat, or genetically controlled adaption to environmental conditions. The Research Topic covered a plethora of methodological approaches as suggestions for best practices in the light of a particular research question and to a wider view to different research disciplines and how they utilize their state-of-the-art techniques in demonstrating potential use cases across different scales.
