Abstract This chapter examines the five Central Asian countries (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan), the critical climate challenges in the region, and the actions taken in response to the climate crisis. It analyzes significant regional climate vulnerabilities, including extreme weather events, water shortages, air pollution, glacial melting, soil degradation, and biodiversity loss. The chapter reviews each country’s institutional climate actions, focusing on the legal frameworks for water management, desertification, and biodiversity and the region’s commitments to international treaties such as the Kyoto Protocol, the Paris Agreement, and the United Nations Sustainable Development Goals. Joint initiatives by these countries to address the regional climate crisis are also discussed. Furthermore, the chapter evaluates noninstitutional actions taken by civil society in response to climate challenges.

Supply chain issues, delays and shutdowns have dominated headlines, impacting individuals' ability to access, and companies' ability to deliver, crucial products and services. Changing consumer behaviours, accelerated by the Covid supply chain shock, have companies struggling more than ever to close the last-mile delivery gap. Attabotics Inc. [2] a Calgary-based robotics company that specializes in inventory management systems, offers a modern solution through its compact vertical warehouse structure and robotic order pickers. Attabotics replaces the rows and aisles of traditional fulfillment centers with a patented storage structure that uses both horizontal and vertical space, reducing a company's warehouse footprint by up to 85%. This empowers retailers, grocers, and ecommerce providers to place different sized fulfillment centers near high-density urban areas, decreasing carbon emissions by closing the last-mile delivery gap. With more than 165 million USD in investment, Attabotics's solution has been adopted by major brands, such as Canadian Tire, and has been featured in multiple venues like The Wall Street Journal, Time Magazine, and Tech Crunch.

The benefits of meadow restoration can be assessed by understanding the connections among geomorphology, hydrology, and vegetation; and multispectral imagery captured from unpiloted aerial systems (UASs) can provide the best method in terms of cost, resolution, and support for vegetation indices. Our field studies were conducted on northern Sierra montane meadows (with ≤70 km2 watershed area). The meadows exist in various stages of ecological restoration. Field survey methods included GPS + laser-leveling channel survey, cross-sections, LiDAR, vegetation sampling, soil measurements, and UAS imaging. A sensor captured calibrated blue (465–485 nm), green (550–570 nm), red (663–673 nm), near infrared (NIR) (820–860 nm), and red-edge (712–722 nm) bands at 5.5 cm resolution (as well as thermal at 81 cm resolution) and provided multispectral images and derivative vegetation indices such as the normalized difference vegetation index (NDVI) and red-edge chlorophyll index (Clre). This fine-scale imagery extended our morphometric assessment of post-restoration channel bedform patterns and sinuosity related to Carex-influenced soil properties and Salix influence, and also documented groundwater-related effects via Carex patterns evident from spring snowmelt images, as well as NDVI and Clre (derived from spring and summer images) in growing to senescent phenological stages. Carex was significantly associated with low bulk density and high soil moisture, NDVI, and Clre in low-lying areas, and channel sinuosity was significantly associated with willow influence. Our methods can be applied by restoration managers to assess where projects are threatened by renewed incision and to document levels of carbon sequestration significant to addressing climate change.

Abstract In response to contemporary changes in climate, many tree species are shifting upslope to find favorable habitat. In the case of obligate ectomycorrhizal species, seedling growth above upper treeline depends on fungal spore availability. In the mountain ranges of the Great Basin, a recent shift in tree species stratification has been recorded, with limber pine (LP, Pinus flexilis) leapfrogging above the ancient bristlecone pine (BCP, Pinus longaeva) forest and establishing above current treeline. We compared the ability of LP and BCP to interact with soil spore banks collected at different microhabitats (next to dead trees, young live trees or in a treeless control) above current treeline in the White Mountains of California. We found an ectomycorrhizal fungal spore bank community composed of 15 species that was dominated by an undescribed and a hitherto unsequenced species of Geopora and Rhizopogon, respectively. This represents a much richer community than was found previously in this system. While both LP and BCP were able to establish ectomycorrhiza, LP was twice as likely to do so, and when comparing only seedlings that were colonized, its root system was colonized to a three‐fold greater extent. BCP seedlings grown on soils collected under young live trees were much more likely to be colonized compared to soils from the other two microhabitats. Synthesis. These differences in ectomycorrhizal receptivity might help to explain why LP is currently establishing at higher rates above the BCP treeline. Furthermore, it is possible that LP saplings above treeline can provide ectomycorrhizal facilitation for BCP seedlings, enabling the subsequent shift of BCP above treeline.

Diabetes is the leading cause of end-stage renal disease (ESRD) in the USA [1]. The prevalence of diabetic kidney disease has increased steadily in proportion to the prevalence of diabetes [2]. Most patients with advanced diabetic kidney disease are overtly proteinuric. Still, clinicians are encountering diabetic patients without proteinuria, and at times even without microalbuminuria, who suffer from advanced chronic kidney disease (CKD) that seems out of proportion to nondiabetic patients with similar co-morbidities.
