Geological Data and the Future of
Agriculture
In our modern world, change is everywhere. The ongoing COVID pandemic has altered life for the vast majority of global citizens, for starters. Thanks in large part to human activities and behavior, climate change is rampant, and its effects can be seen across multiple disciplines.
The geological impacts of climate change are wide-reaching, and there’s myriad evidence of the phenomenon across the geological record. Rising global temperatures and high CO2 concentrations directly impact ocean levels and can cause irreparable harm to both marine and terrestrial ecosystems. The global food supply is also reeling from the effects of climate change, and the future of agriculture hangs in the balance.
The good news is that, when it comes to agriculture, there's plenty to learn from geological data. The various types of geologic data collected across history include geophysical surveys, chemical analyses of groundwater and soil, and earthquake location data. With that data in hand, geology enthusiasts, farmers, and consumers alike can make more informed decisions about agriculture moving forward.
Here’s what you need to know about the global
efforts to address climate issues including water scarcity and fresh food
access, with a little help from geologic data.
Climate
Change, Farming, and the Geologic Record
From a geological perspective, climate change is nothing new, yet it looks much different in the 21st century. According to the Geological Society of London, current CO2 levels are at the highest levels in at least the past 3 million years. In addition, “the current speed of human-induced CO2 change and warming is nearly without precedent in the entire geological record.”
It’s clear that we’re at a tipping point in terms of climate change, and no industry is unaffected. Once a fringe concept, sustainability is now at the forefront of many global minds, and promoting sustainable agriculture is of crucial importance. Modern farmers currently face the daunting task of keeping crop yields high without harming the environment.
In an effort to support healthy soil, global farmers collect relevant soil data using a variety of methods and technology. Whether sourced via ground penetrating radar (GPR), electromagnetic induction (EMI), or another method altogether, measurements are used to determine soil attributes and features, as well as to detect any contaminants that may be present.
Once contaminants are detected, farmers are
then tasked with finding the origin and eliminating it. In many cases, polluted
groundwater is the culprit. Contaminated groundwater can cause detrimental harm
to the surrounding environment, including agriculture fields, but data
collection may help mitigate some of the damage.
Using Data to Detect Pollutants
There may be a variety of potential groundwater contaminants depending on a farm’s location, including agricultural chemicals, and scientific tests can help determine the true cause. Yet the work doesn’t end there, and contaminated groundwater may still pose a hazard to humans and the natural environment years after the initial pollution event. Data collection is thus a long-term effort for farmers and residents in areas affected by polluted groundwater.
In the town of Libby, Montana, for instance,
the Environmental Protection Agency discovered the dangerous chemical
pentachlorophenol in a resident’s well water in 1979. Lumber and sawmill
companies in the area were determined to be the source, and clean-up efforts
commenced. Subsequent tests found additional contaminants, however, and safety reviews are still conducted every five years
in an effort to keep residents safe. Groundwater sourced outside the city
limits of Libby remains questionable, potentially impacting agricultural
production in the region.
The
Agricultural Applications of Geologic Data
Today’s advanced technology allows us to collect more data than ever before and centralize that data in order to extract meaningful insights. No matter how much data you have at your fingertips, however, it’s not necessarily worth much if you can’t make practical use of that information. Turning raw data into interpreted data takes everyone involved in the process, from geologists and social scientists to the farmers who understand how to best apply that data to their advantage.
Consumer trends are also an important part of agriculture, as the demand for certain products and foods can shift dramatically over time. By looking at data related to consumer grocery shopping habits, researchers may be able to identify problem areas, like where there may be too much or too little of a particular type of produce available in a geographic location, for instance.
Around the world, food deserts are becoming more prevalent in both rural and urban areas, even in developed countries. The Annie E. Casey Foundation reports that, within the U.S., 6.2% of the population lives in an area with limited access to fresh food — also known as a food desert. Going forward, the ability to optimize agriculture data will be a crucial factor in adjusting to growing populations and rising urbanization.
Healthcare professionals are even getting in
on the action, by collecting patient data that can be used in agricultural
applications. In increasing numbers, doctors are now screening for various
social determinants of health, notably food insecurity, asking patients about where they buy groceries
and how easy it is to get to the grocery store. Among other useful data, social
screenings allow researchers to get a better look at a population’s overall
ability to meet basic needs.
Data related to social demographics can be
used in tandem with geological data in order to address gaps in the realm of
agriculture. As an example, today’s socially conscious young people often find
themselves at the intersection of technology and climate concerns.
Young people can be a catalyst for change when given the opportunity and tools
to do so. In this way, geological and environmental data can engage young
people in research, opening up questions about the future of agriculture and
paving the way toward a prosperous future.
Final
Thoughts
Among its important lessons, geology teaches us that change is constant when it comes to the Earth’s climate. In large part due to the actions of humans, the world is changing at a rapid pace, but geological data may offer solutions.
It’s an exciting time for those interested in geoscience, as the practical applications of geological data can no longer be ignored. Indeed, the very future of agriculture may depend on geological data, as well as our ability to make the necessary changes to ensure a future where there’s plenty of healthy food, and no one goes hungry.
