Massive 8,000-mile “dead zone” could be one of the gulf’s largest

By Sarah Gibbens

Record-breaking rainfall across the midwest has washed tons of fertilizer and sewage water along the Mississippi and into the Gulf of Mexico, contributing to a larger polluted area than ever.

Fields: The Transformation and Healing of the Whitewater Valley

They say hindsight is 20/20. Farmers of the past didn’t have information about environmentally friendly agricultural techniques. The farming techniques used today to reduce erosion and other negative environmental effects were developed as we learned from agriculturally derived disasters. Situated in the Whitewater River Valley less than 10 miles from the confluence with the Mississippi River, Beaver, Minnesota was one such town that suffered…

Eyes on Large Lakes

“A lake is a landscape’s most beautiful and expressive feature. It is Earth’s eye; looking into which the beholder measures the depth of his own nature.” So said H.D. Thoreau in Walden, conjuring an image of human eyes peering intently into Earth’s eyes, and learning something profound in the process. Indeed, who among us hasn’t gazed into one of these watery eyes of Earth, into a lake’s mysterious depths, and had their souls stirred, their curiosity piqued?…

The Future of Agriculture in a Water-Rich State

In 1920, Minnesota held 2.4 million people and 132,744 farms. Corn production was near 100 million bushels per year. By 1929, 18.5 million acres were under cultivation. Nearly 100 years later, the state has 5.4 million people, 74,500 farms, and 26 million acres of farmland. Annual production of corn is about 1.5 billion bushels and soybean is about 380 million bushels. Over that century, agricultural technology and infrastructure changed profoundly…

Mosquitoes, Muck, and Mussels: A Look Into Scientific Research

The aspiring young undergraduate scientists envision fieldwork as a romantic escape from the office cubicle, classroom desk, and seemingly endless pile of homework. Working alongside experts in their field, they anticipate working in the wildest regions of the world: dense tropical forests, remote mountain ranges, and distant glacial rivers. They see themselves on the forefront of groundbreaking discoveries: truly shattering the scientific community with a cure for Malaria, discovery of a new species, or theory of planetary evolution.

Minnesota has 2,669 troubled bodies of water, draft list says

By Kirsti Marohn

Minnesota, which prides itself as the “land of sky-blue waters” and “land of 10,000 lakes,” has determined that a substantial number of those waters are seriously polluted. Ongoing monitoring reveals that a few surface water bodies are improving, but much work remains to meet state goals.

Introduction

Introduction to Issue Fourteen

Climate change has virtually exploded as a subject of news reports, scientific analysis, and advocacy attention in the past six months. In November, the United States Global Change Research Program released its Fourth National Climate Assessment. Longstanding debates about the relative importance of mitigation and adaptation have further receded in urgency as this spring’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) finding that a million species are threatened with extinction have grabbed headlines worldwide.

Introduction

Guest Editors’ Introduction to Issue Fourteen: Climate, Change & People

Archaeologists, by definition, are interested in using various techniques to learn about the human experience in diverse places, from ancient through contemporary times. A key part of this has been understanding human adaptation to diverse environmental and climatic changes over time, and for archaeologists, the long arc of human existence refers to at least around three million years.

Multiple Ways of Understanding Peru’s Changing Climate

In this article, we consider how the perspectives and experiences of contemporary people facing climate change can enrich our archaeological interpretations of climate change in the past. In particular, we present an ethnographic study from highland Peru that highlights the complex and varied ways people are responding to environmental uncertainty, and explore how their perspectives and responses have led us to question and expand the narratives we construct about ancient people.

Uncovering Amazonia

“Amazonia”—the word alone can conjure up a lot of images, some accurate and some wildly not. In truth, it has many definitions, ranging from a specific drainage basin to a tropical ecological world. For most of my childhood, such kinds of tropical “jungles” were places of peril to be avoided. The very word “Amazon” conjured up Joseph Conrad’s images from Heart of Darkness ([1899] 2015), albeit that book was about the Congo in Africa.

Ethnography and Archaeology of Water in the Maya Lowlands

Procuring potable water is an important factor for daily life in the semitropics, especially for contemporary populations in rural Guatemala. Seasonal subsistence practices are crucial for survival, especially regarding agriculture, droughts, and flooding. This article focuses on the Salinas de los Nueve Cerros region in Alta Verapaz, Guatemala to highlight contemporary land-use practices among the Q’eqchi’ Maya, their adaptations to flooding, droughts, and uses of different water resources.

Libraries Burning

The impact of climate change on archaeological and heritage sites in the Arctic region is devastating. New techniques of research and analysis are providing increasingly rich data about the long history of humans in the environment. Just as the value of these sites is being recognized more fully, the sites themselves are being destroyed by thawing permafrost, rising sea levels, and increasingly violent storms. Nowhere is this being felt more intensely than in the Arctic, which is warming two to three times as fast as the rest of the planet (Hoag 2019).

Desert River Sea is a Vibrant, Compelling Tour of the Kimberley

For the past century, the curator has been the deciding factor in what is shown by museums and galleries, reassuring audiences of the importance of what they are seeing. While acknowledging other commercial and audience drivers, the centrality of curatorial decision-making has been sacrosanct. But when the curatorial team from the Art Gallery of Western Australia embarked on an epic quest to document the art of the Kimberley region in the state’s north west, they abandoned this idea of a single authorial voice in favor of a new model of partnership and exchange.

An Archaeologist Writes against the Anthropocene

Much of what archaeologists do is study how humans adapt to the environment. After Gordon Willey’s (1953) groundbreaking investigation into the entire history of occupation of a small valley in Peru, understanding how humans lived in and modified their environment became commonplace. Indeed, the “New Archeology” that took the American academy by storm in the 1960s and strove to make the discipline more scientific made human-environment interactions and the understanding of human-environmental relations one of its central goals...

Water and the Preclassic Maya at El Tintal, Petén, Guatemala

As part of the 1931 Carnegie Institution of Washington’s Uaxactun expedition, geologist C.W. Cooke (1931: 286) noted, “If the bajos were restored to their former condition, the Petén would be a region of many beautiful lakes. Travel in it would be easy, for one could go from place to place by boat, with only short journeys overland, from one lake to another, across country that offers little impediment to travel at any season.” These bajos mentioned by Cooke, low-lying swampy areas prone to flooding, are spread throughout most of the northern lowlands of Petén, Guatemala, characterizing the region with seasonal and perennial wetland systems.

The Perils and Promise of Using Short-Term Media to Teach Long-Term Climate Patterns

A concern for climate change has burst onto the national media, scientific literatures, and other discourses over the past year. As someone who teaches in design- and natural resource-oriented fields, I feel an obligation to equip my students with critical awarenesses of the patterns, as well as a sense of what they can do, professionally and personally, to face this crisis.
