Oil waste was everywhere—on the roads, in the rivers where they fished, and in the water that they used for bathing, cooking, and washing. Children became sick and died, cases of stomach cancer skyrocketed, and women miscarried or gave birth to children with congenital disorders. The American oil company Texaco—now part of Chevron—extracted its first barrel of crude oil from Amazonian Ecuador in 1972. It left behind millions of gallons of spilled oil and more than eighteen million gallons of toxic waste. In Crude, Ecuadorian lawyer and activist Pablo Fajardo gives a firsthand account of Texaco’s involvement in the Amazon as well as the ensuing legal battles between the oil company, the Ecuadorian government, and the region’s inhabitants. As a teenager, Fajardo worked in the Amazonian oil fields, where he witnessed the consequences of Texaco/Chevron’s indifference to the environment and to the inhabitants of the Amazon. Fajardo mobilized with his peers to seek reparations and in time became the lead counsel for UDAPT (Union of People Affected by Texaco), a group of more than thirty thousand small farmers and indigenous people from the northern Ecuadorian Amazon who continue to fight for reparations and remediation to this day.Eye-opening and galvanizing, Crude brings to light one of the least well-known but most important cases of environmental and racial injustice of our time.

Since 2014, CARTHA has provided a platform for critical thinking on architecture and society. Each year, CARTHA initiates research and publishes issues on a topic in its online magazine, which are then brought together in an annual book. In 2016, CARTHA was invited to participate in the Lisbon Architecture Triennale. Adopting the Triennale's topic, 'The Form of Form', the three issues that comprise CARTHA on the Form of Form explore the topic of form through different, yet complementary, lenses. The first issue, How to Learn Better, was edited by Bureau A and discusses pedagogical approaches to architecture. The second issue, The Architecture of the City: A Palimpsest, edited by Victoria Easton, Matilde Cassani, and Noura Al Sayeh, revisits and reinterprets Aldo Rossi's writings on the form of the city. Published during the Triennale, the third issue, Lisboa Paralela, was edited by the CARTHA editorial board and expands on urban forms by questioning the status quo of natural and social laws and speculating on these through essays and a design exercise by some of the most interesting voices of the current architectural scene.

In the wake of 500 years of colonialism, the Caribbean archipelago remains to this day one of the world’s most profoundly fractured regions of the world. Spain, Germany, England, the Netherlands, and the United States claimed various parts of the island group, primarily to assert their economic interests. The resulting mosaic concealed the region’s own, non-Eurocentric culture and art. But, now, the social, political, and cultural dynamics are shifting. In partnership with the Basel H. Geiger Cultural Foundation, The Caribbean Art Initiative, which was founded in 2019 to raise international awareness of the rich Caribbean art scene, will present the first large-scale exhibition of contemporary Caribbean art by Caribbean curators in Basel, Switzerland. This companion publication showcases artists from all over the region and its diaspora, making their works broadly accessible and initiating a much-needed conversation about an otherwise overlooked facet of the international community.

For the past twenty years, international donors have invested heavily in large-scale disarmament, demobilization, and reintegration (DDR) programs, while, at the same time, transitional justice measures have proliferated, bringing truth, justice, and reparations to those recovering from state violence and civil war. Yet DDR programs are seldom deconstructed to discover whether they truly achieve their justice-related aims. Additionally, transitional justice mechanisms rarely articulate strategies for coordinating with DDR. Disarming the Past examines the connections--and failures--between these two initiatives within peacebuilding contexts and evaluates future links between DDR programs and the aims of transitional justice. The outcome of a substantial research project initiated by the International Center for Transitional Justice (ICTJ), this book is crucial for anyone interested in effective interventions and enduring outcomes.

Gego infused her art with architecture and engineering to create unique works of delicate suspense Accompanying the first major museum retrospective exhibition of Gego’s work in the US in more than 15 years, this expansive, definitive catalog charts the evolution of Gego’s singular approach to abstraction through organic forms, linear structures and systematic spatial investigations. Featuring nearly 300 images, including more than 160 sculptures, drawings, prints, artist’s books, textiles and installations made between the early 1950s and the early 1990s, this volume also presents 11 illustrated essays by experts in the field of modern and contemporary Latin American art that trace Gego’s artistic development across various mediums and disciplines, including her significant contributions to architecture and design; ground her practice in various art movements that materialized in Latin America, Europe and the US during her lifetime; and consider the pedagogical influence of her two-decade teaching career in Caracas. An illustrated chronology tracks Gego’s life and artistic progression as well as her exhibition history, contextualized within the rich cultural milieus in which she lived and worked. Also featured are images of Gego’s Reticulárea, an environmental installation widely considered to be her magnum opus, and a series of photographs taken by the artist’s partner at their shared home and studio in Caracas. Gego remains little known in the US today, despite her unique and striking formal and conceptual contributions. This essential publication advances an expanded understanding and appreciation of the artist’s work within the context of 20th-century modernism. Gego (Gertrud Goldschmidt, 1912–94) came of age as an artist in the midst of Venezuela’s development as a modern state, emerging as a vital figure in Latin American modern art whose work intersected with major transnational art movements of the 20th century while remaining distinctly her own. Born in Hamburg and trained as an engineer and architect in Germany, Gego immigrated to Venezuela in 1939, fleeing Nazi persecution. In her new home of Caracas, she worked as an architect and a designer before embarking on her artistic career, which she pursued until her death in 1994.

The images of Pablo López Luz are sensitive to the tensions in the urban landscape, expressing the relationship of city dwellers to their environment and, in particular, to those tensions in which the collective memory is encrypted. This is the spirit that informs the artist’s photo essay about various buildings in the capital city constructed with volcanic stone, a material that evokes the massive forms of pre-Columbian architecture. The enormous metropolis, frequently shaken by seismic activity, is spread out under the gaze of Popocatéptl, over 5,000 meters high, and has itself encroached on the slopes of the Ajusco, a dormant volcano lying to the south.

This book presents a significant amount of structural, paleomagnetic and magnetic fabric data in the Central High Atlas (Morocco). The authors thoroughly described and analyzed the present-day structure of this intraplate chain through 22 of cross-sections, potential field data analysis and 3D reconstruction. In addition, the authors propose a palinspastic reconstruction of the structure of the basin at 100 Ma (i.e., post-extension and pre-compression) to finally evaluate its Mesozoic and Cenozoic geodynamic evolution. This books presents (1) a unique three-dimensional model at the chain scale, (2) an analysis of the ca. 100 Ma remagnetization, to perform palinspastic restorations of most representative structures, (3) as well as the interpretation of the magnetic fabrics in order to unravel the tectonic or deformation setting that the rocks underwent in different parts of the basin. This book is of interest to structural geologists in Northern Africa, the Mediterranean and Iberia, as well as to those interested in inverted intraplate basins and paleomagnetists from around the planet. Also, this book is intended to help students to understand better the geological evolution of the Atlas and therefore Morocco and surrounding areas.
