As the largest alpine valley in the world, the San Luis Valley is a land of sand dunes, wetlands, andfarmland-nearly all of it above 8,000 feet in elevation. It is characterized by an unparalleled rangeof physical geography, social, cultural, and economic diversity, and extraordinary environmentalphenomena-all within a footprint of roughly 150 by 75 miles. Only sparsely covered by historiansand geoscientists, the San Luis Valley has been home to mixed Hispanic ancestral villages, Spanishand Anglo settlements, Indigenous territories, and Catholic, Mormon, Amish, Hindu, and Buddhistcommunities. Today, the vast majority of land is owned by state or federal agencies or is usedfor agricultural production. Dominated by the presence of the Rio Grande, one of the main riversin the American Southwest, the San Luis Valley is the headwaters of many lifeways that flow andbranch out across the region. This publication summarizes M12 studio's Landlines Initiative, amulti-year engagement with Colorado's rural San Luis Valley, which took place from 2018 to 2022.M12 is a collaborative studio known for art projects that explore public space, rural cultures, andlandscapes.

An anthology that accompanies Culturescapes 2023 Sahara, the 17th edition of the Swiss multidisciplinary festival. Sahara: A Thousand Paths Into the Future is devoted to the ideas, images, poetics, politics, fictions, and movements of this vast desert and its myriad voices. Focused on the cultural productions, lines of political and aesthetic thought, and multiple epistemologies and cosmologies of the Sahara, and the accompanying Sahel, this book understands the region as both an ancient space of connection and circulation--from its northern to southern shores, its dunes and volcanic mountains, to its lusher savannahs--and as a contemporary site of exchange between strikingly singular societies and communities on all sides of the desert, that aspect of the Sahara most often imaged and imagined. If the Sahara is habitually narrated as a space of radical heat and intense light, and of barren-like emptiness, this anthology approaches the region with a decolonial lens that privileges the Saharan communities and nonhuman entities who live within all aspects of its circadian rhythms, including the constructive opacity of the desert night. The violence of enlightenment and its imperialisms have often been practiced under the glare of some narcotic sun--the imaginaries of coloniality still do--yet in the desert, it was the elaborating darkness of its night skies, with their spectral constellations, that often directed caravans on their historical routes. They still do. Thus the thinkers, artists, poets, choreographers, composers, activists, elders, novelists, historians, and translators whose voices and sensibilities score and structure this anthology create a more full-spectrum and polyphonic sense of what the Sahara means, in all its waves and forms. Sahara: A Thousand Paths Into the Future indicates a prismatic space of cultures, ecologies, knowledges, conflicts, languages, lights, and relations. That is, of numerous pasts and possible futures.

The little-known history of how the Sahara was transformed from a green and fertile land into the largest hot desert in the worldThe Sahara is the largest hot desert in the world, equal in size to China or the United States. Yet, this arid expanse was once a verdant, pleasant land, fed by rivers and lakes. The Sahara sustained abundant plant and animal life, such as Nile perch, turtles, crocodiles, and hippos, and attracted prehistoric hunters and herders. What transformed this land of lakes into a sea of sands? When the Sahara Was Green describes the remarkable history of Earth's greatest desert-including why its climate changed, the impact this had on human populations, and how scientists uncovered the evidence for these extraordinary events.From the Sahara's origins as savanna woodland and grassland to its current arid incarnation, Martin Williams takes us on a vivid journey through time. He describes how the desert's ancient rocks were first fashioned, how dinosaurs roamed freely across the land, and how it was later covered in tall trees. Along the way, Williams addresses many questions: Why was the Sahara previously much wetter, and will it be so again? Did humans contribute to its desertification? What was the impact of extreme climatic episodes-such as prolonged droughts-upon the Sahara's geology, ecology, and inhabitants? Williams also shows how plants, animals, and humans have adapted to the Sahara and what lessons we might learn for living in harmony with the harshest, driest conditions in an ever-changing global environment.A valuable look at how an iconic region has changed over millions of years, When the Sahara Was Green reveals the desert's surprising past to reflect on its present, as well as its possible future.

Ny spændingsroman af finske Leena Krohn (Ikke før solnedgang m.fl.)Meteorologen Leena Lind finder en mærkelig genstand på en ø, en slags fløjte. Dens baggrund kender hun ikke, men på godt og især ondt lærer hun dens effekt at kende.Tordenfløjten er en roman om menneskets dybe drift efter at kunne kontrollere vejret, uanset om det er med magi eller teknologi – og uanset konsekvenserne ... for en seksårig pige eller for en skrøbelig global magtbalance.Johanna Sinisalo, dronningen af spekulativ fiktion, tegner i sin nye roman en elementært (i ordets egentligste forstand) spændende, men uhyggelig bue fra antikken til nutiden. Nøgleordet er fulgurit. Eller rettere – profit.Johanna Sinisalo (f. 1958) er ophavskvinde til et omfattende forfatterskab, i høj grad kendt for med stilistisk succes at bringe træk af SciFi og fantasy ind i mere litterær fiktion. Hun er oversat til mere end 20 sprog. På dansk er udkommet hendes Finlandia-prisvindende debutroman fra 2000 Ikke før solnedgang (2020); chili-romanen Solens kerne (2013, da. 2019); og den tidlige CliFi-roman Englenes blod (2011, da. 2021), sat i en nær fremtid, hvor økosystemerne bryder sammen pga. manglen på bier til bestøvning. Tre romaner der kan siges at have været profetiske i forhold til opgøret med såvel sexisme som antropocentrisme.

A Argélia (ou El Djezaïr) está localizada no norte do continente africano banhada pelo Mar Mediterrâneo e faz parte da União do Magrebe Árabe (AMG). Sua superfície é de 2.381.741 km². A Argélia é o maior país da África, do mundo árabe e da bacia do Mediterrâneo, e o décimo maior país do mundo. Tem 1.622 km de costa mediterrânea. A Argélia compartilha mais de 6.385 km de fronteiras terrestres com vários países. Tem fronteiras comuns com sete países vizinhos, a saber: Tunísia no Nordeste. Líbia no Oriente. Níger e Mali no Sul. Mauritânia e República Árabe Saharaui Democrática (RASD) no Sudoeste. e Marrocos no Ocidente. A Argélia está dividida em 58 províncias (wilayas) que são autoridades regionais descentralizadas do Estado. Têm personalidade jurídica e autonomia financeira. São também distritos administrativos descentralizados do Estado com dois órgãos: Assembleia Provincial Popular (APW), órgão deliberativo. O prefeito (Wali), órgão executivo e representativo do Governo. Cada província (wilaya) abrange um número específico de municípios. O Daïra (subdivisão) é uma extensão administrativa da província. Assim, as 58 províncias incluem 1.541 municípios e 535 Daïras. A Assembleia Provincial do Povo (APW), que é o órgão deliberativo, delibera por deliberação sobre assuntos da sua competência e sobre qualquer assunto de interesse da província. O Prefeito (Wali), nomeado pelo Presidente da República, é representante do Estado e representante da província. Ele garante a aplicação das leis e regulamentos e garante a implementação das decisões da Assembleia Provincial do Povo (APW). Cada município tem seu próprio órgão deliberativo, a Assembleia Municipal Popular (APC), que elege seu próprio presidente, que atua como prefeito. A taxa de urbanização da Argélia é de cerca de 60% e está em constante crescimento. A Argélia tem mais de trinta e sete áreas urbanas com mais de 100.000 habitantes, quase todas concentradas no norte do país. A cidade densamente povoada é a capital Argel, uma megalópole de mais de seis milhões de habitantes, tornando-se a primeira cidade do Magreb. A Argélia tem uma posição geográfica privilegiada e uma área considerável. É composto por diferentes paisagens, áreas montanhosas, paisagens mediterrânicas, vastas terras altas semi-áridas e áreas desérticas lunares. No norte da Argélia, predomina o clima mediterrâneo, com verões quentes e úmidos e invernos amenos.

A career-spanning collection of Bruce Berger's beautiful, subtle, and spiky essays on the American desertOccupying a space between traditional nature writing, memoir, journalism, and prose poetry, Bruce Berger's essays are beautiful, subtle, and haunting meditations on the landscape and culture of the American Southwest. Combining new, unpublished essays with selections from his acclaimed trilogy of "desert books"-The Telling Distance, There Was a River, and Almost an Island-A Desert Harvest is a career-spanning selection of the best work by this unique and undervalued voice.Wasteland architecture, mountaintop astronomy, Bach in the wilderness, the mind of the wood rat, the canals of Phoenix, and the numerous eccentric personalities who call the desert their home all come to life in these fascinating portraits of America's seemingly desolate terrains.

On the periphery of Scottsdale, Arizona is a troubling reminder of the consequences resulting from suburban expansion and desert encroachment. The silent victims are powerless to protest or alter the unblinking destiny of development. Gashed, wounded, and disfigured cacti litter the remaining vacant terrain, rapidly disappearing into subdivisions of residential housing tracts, strip malls, and commercial constructions. Author and photographer Marques Vickers book "Cactus Cadavers: Vanishing Phantoms of Suburban Sprawl" illustrates this gradual erosion of Arizona's heritage treasure. Their declining presence become emblematic of society's continuing disharmony with our surrounding environment. Earliest human settlement of the Salt River Valley, the terrain of contemporary Phoenix, commenced with nomadic paleo-Indians. These earliest civilizations inhabited the Americas during the final glacial episodes of the late Pleistocene period, approximately 6,000 BC. Tribes hunted mammoths, mastodons, giant bisons, camels, and giant sloths that eventually migrated eastward. The initial nomadic tribes followed vacating the region. Tribes originating from Mexico to the south and California to the west would replace them. Around 1,000 BC, a subsequent core of settlements would inhabit the territory. Corn farmers, builders, and permanent villagers would evolve into the Hohokam civilization. Within 500 years, the Hohokam culture had established an elaborate canal system enabling agriculture to flourish. Around 1450, the Hohokam suddenly and mysteriously disappeared. By the 16th century arrival of Europeans, the O'odham and Sobaipuri tribes primarily inhabited the region.>The availability of air conditioning to counter the oppressive summer dry heat stimulated a post-World War II population surge. The Phoenix metro area has increased in population an estimated average of 4% for the past forty years. Phoenix is the fifth largest city in American with projections that it may become the fourth within the next five years. This growth proliferates to accommodate a swelling and aging population migration seeking the warmer climate the Arizona desert can accommodate. One day, the cacti's diminishing and lost presence may be mourned once the transitional madness subsides. In the meanwhile, this edition illustrates the decline of these desert patriarchs. It seems unimaginable that amidst the expansive desert landscape these icons could ever entirely vanish. Yet like the mammoths and Hohokam civilization from centuries past, adaptation for them becomes difficult if not impossible. Domestically cultivated cacti may only emulate the nobility of their freely born brethren that tower majestically amidst the desert landscape.
