Growing Conditions

The key factor in the choice of perennial legume grasses in the face of climate change is their drought resistance, because the development of roots directly affects this property, as well as determines their fertility. The purpose of the study was to establish what morphological and biological characteristics of grass roots ensure economic characteristics in the context of climate change. Methods of observation, comparison, and field experiment were used. The study found that the roots of alfalfa have the greatest depth in the soil, spread in the horizontal direction, the thickness of the root neck and lateral roots, which ensures plasticity, durability, and productivity of its crops. The roots of white melilot have the greatest depth in the soil, the thickness of the root neck, central root and lateral roots, their spread in the horizontal direction, which affects the drought and frost resistance of crops. The roots of birdsfoot trefoil are distinguished by the greatest number of renewal buds on the root neck, the smallest depth, and the thickness of the root neck, which affects productive longevity and the possibility of growth in poor and acidic soils. The roots of eastern galega have the greatest depth of the main plant, distribution in the horizontal direction, the thickness of the central root, which affects productive longevity and high biological plasticity. The roots of Hungarian sainfoin are distinguished by the greatest distribution in the horizontal direction and the deepest placement of the main branching, which affects high biological resistance to adverse growing conditions. It was also found out that the roots of meadow clover have the smallest spread radius in the horizontal plane, the thickness of the central and lateral roots, which determines the possibility of its cultivation in the field crop rotation. These findings would facilitate the selection of perennial legume grasses to achieve their full potential in the face of climate change

Affective Dimensions

Resilience calls forth stories of ingenuity and resourcefulness in the face of a greater power. This could be a force of nature (hurricanes, tornados, earthquakes, drought), human-made destruction (wars, industrial accidents, terrorism, climate change), or simply meeting up with the neighborhood bully on the playground. Although it is currently used in discussions of economics and technologies, as well as in reference to people and the natural world, resilience demands an accounting with the more affective dimensions of our experience. Eventually, with time (suspension) and support (gravity), lives are reimagined, buildings are reconstructed, and we try to establish a new sense of balance. But resilience also carries the possibility of lasting transformation. Often in returning and remembering, we find that we no longer want what we had before. Natural ecologies, human communities, and complex systems can all exhibit resilience; it is necessarily a grass-roots movement.

The arid border region that encompasses the American Southwest and the Mexican northwest is an area where the nexus of water scarcity and climate change in the face of growing human demands for water, emerging energy scarcity, and economic change comes into sharp focus.

The Relationship

The article deals with the problem of achieving sustainable development. The purpose of this study is to reveal the relationship between the components of sustainable development, taking into account the involvement of indigenous peoples in nature conservation. Climate change makes achieving sustainable development more difficult. Indigenous peoples are the first to feel the effects of climate change and play an important role in the environmental monitoring of their places of residence. The natural environment is the basis of life for indigenous peoples, and biological resources are the main source of food security. In the future, the importance of bioresources will increase, which is why economic development cannot be considered independently. It is assumed that the components of resilience are interrelated and influence each other. To identify this relationship, a model for the correlation of sustainable development components was developed. The model is based on the methods of correlation analysis and allows to determine the tightness of the relationship between economic development and its ecological footprint in the face of climate change. The correlation model was tested on the statistical materials of state reports on the environmental situation in the Khanty-Mansiysk Autonomous Okrug – Yugra. The approbation revealed a strong positive relationship between two components of sustainable development of the region: economy and ecology.

This is the first book to treat the major examples of megadrought and societal collapse, from the late Pleistocene end of hunter–gatherer culture and origins of cultivation to the 15th century AD fall of the Khmer Empire capital at Angkor, and ranging from the Near East to South America. Previous enquiries have stressed the possible multiple and internal causes of collapse, such overpopulation, overexploitation of resources, warfare, and poor leadership and decision-making. In contrast, Megadrought and Collapse presents case studies of nine major episodes of societal collapse in which megadrought was the major and independent cause of societal collapse. In each case the most recent paleoclimatic evidence for megadroughts, multiple decades to multiple centuries in duration, is presented alongside the archaeological records for synchronous societal collapse. The megadrought data are derived from paleoclimate proxy sources (lake, marine, and glacial cores; speleothems, or cave stalagmites; and tree-rings) and are explained by researchers directly engaged in their analysis. Researchers directly responsible for them discuss the relevant current archaeological records. Two arguments are developed through these case studies. The first is that societal collapse in different time periods and regions and at levels of social complexity ranging from simple foragers to complex empires would not have occurred without megadrought. The second is that similar responses to megadrought extend across these historical episodes: societal collapse in the face of insurmountable climate change, abandonment of settlements and regions, and habitat tracking to sustainable agricultural landscapes. As we confront megadrought today, and in the likely future, Megadrought and Collapse brings together the latest contributions to our understanding of past societal responses to the crisis on an equally global and diverse scale.
