These are the CASSE blog articles on food and agriculture.
Humans have come to rely on chemicals not only to increase the fruits of our agricultural labor but also to stop other species from partaking in the feast. And the toll exacted by these “pest”-killing chemicals is immense.
Over 60 years ago, in Silent Spring, Rachel Carson detailed the effects of DDT, the first widely used chemical pesticide, on ecosystems and human health.
The science is clear: Our rate of economic activity is having disastrous impacts on the environment, starting with the climate so crucial to our survival. Economic activities require the use of natural resources and systematically entail pollution. Resources eventually get used up, as does the capacity of the planet to assimilate waste. We are reminded of Herman Daly’s long-running emphasis that the economy is a subsystem of the environment,
Given his long-running obsession with GDP growth, an obsession punctuated with mid-terms in mind, President Trump has made some peculiar moves. Just this week, his stripping of immigrant truckers’ licenses took effect, as part of a broader crackdown on immigrant labor, a key source of economic growth. His hyperactive imposing of tariffs has undermined comparative advantage, a condition relied upon for global GDP growth.
The size of our economy, measured by gross domestic product (GDP), is intimately linked to our use of artificial fertilizer. So is the ecological havoc we are wreaking on the planet and its inhabitants.
Between 2002 and 2018, while the population increased by 22 percent, the per-hectare use of synthetic nitrogen, phosphorus, and potassium fertilizers—the three most common types—increased by about 23,
Say what you will—pro or con—about the nutritional merits of the Trump Administration’s new food pyramid, but the thing is a masterclass in political artistry. It systematically serves vested interests, a political party, and an ever-competing president. And, I’ll argue, it’s subtly designed for a surge in GDP.
On its face, it certainly is an artistic endeavor, designed to grab you from several angles. The first thing to catch your eye is its surprising disposition.
Finney County lies in the southwest quadrant of Kansas and above the massive Ogallala Aquifer. Running mid-continent from the Dakotas to Texas, the Ogallala is the largest aquifer in North America. Once holding the volume equivalent of Lake Huron, the aquifer was first tapped for high-volume irrigation in 1909. This fundamentally transformed the landscape from ecologically diverse tallgrass prairie to energy- and water-intensive monoculture crops on an immense scale.
Freshwater is arguably the single most essential resource for human life. Yet, its use seems more abstract than that of solid materials. Freshwater sources exist everywhere that humans do, but they are often hidden from view, buried underground or frozen in glaciers. It’s hard to fathom the scope and the impact of the 3.95 trillion cubic meters of freshwater the human economy extracted in 2021.
What are supposed to be the advantages of the free-trade consensus that has emerged in the last century? Yes, innovative technologies and techniques have made their way around the globe. The diffusion of digital communications, managerial technology, advanced materials engineering, and efficient shipping techniques are but a few prominent examples. The openness and complexity of the global trading system have facilitated this diffusion.
Additionally, trade based on “comparative advantage” has modestly increased global economic efficiency.
The world looked poised to end hunger in the mid-2010s, after decades of decline in the percentage of the population that is undernourished. People often attribute progress in the late 20th century to the technological advances of the “Green Revolution.” However, the revolution’s costs and benefits, and their distribution, are hotly contested. Many experts instead point simply to economic growth as the primary factor responsible for poverty reduction and,
Allamakee County lies in the northeast corner of Iowa, bordering Minnesota and Wisconsin. It is part of a three-state region that, unlike most of the upper United States and Canada, escaped glaciation during past ice ages. This geological oddity is immediately obvious to visitors by the dramatic terrain of bluffs, hills, and valleys. Expansive plains characterize most of the rest of Iowa, where miles-thick glaciers moved over the land like a bulldozer,
