Soils of Change

An agronomist works with rural farmers to help them adjust to climate change.

By Matthew MacGregor

It may seem odd that a former Peace Corps volunteer would help the world’s poor by studying dirt. But Gaye Burpee, an agronomist with Catholic Relief Services (CRS), an international relief and development organization, did just that. After obtaining her doctorate in soil physics, Burpee’s work now is a hybrid between natural resource management and agriculture, which she uses to help Latin American and Caribbean farmers adjust their practices to adapt to climate change. At CRS, she guides agriculture, natural resources, disaster relief, education, microfinance, health, HIV/AIDS, and peace-building programs in 13 countries. (And you thought you were busy!) Plenty caught up with Burpee to discuss how she got involved in her work, what she’s seeing in the field, and who will be most affected by global warming.

What was one of your most interesting experiences as a PhD student?
For a four-year period, I traveled back and forth to the Dominican Republic. My field research focused on harsh growing environments, degraded soils, and resilient tropical crops in a farming and fishing village. I used solar power to run my computer and research equipment; lived in a thatched roofed, mud-floored Ramada; and cooked fresh fish, rice, and beans over an open fire. While I was there, the village was fighting to protect its livelihoods and landscapes from encroachment by illegal over-fishing and indifferent government ministries. Ultimately, they were successful in their fight. To make their point, villagers used satellite images documenting reef and mangrove degradation, and photos of government vehicles with illegal nets on the beach.

How does your training in agronomy help with your work at CRS?   
Soils farmed by the poor in much of the developing world are degraded. The soil is unable to support healthy, vigorous plants and trees; and unable to resist insects, disease, or moderate weather disturbances, let alone natural disaster. The knowledge I need to work with farming families must touch not only on the basics of soils, but on the basics of water, markets, storage, finances, landscapes, weather, crops, pests, small livestock, and trees. Understanding the links between natural resources, rural livelihoods, and poverty enables me to contribute to our programs and the communities we work with in more strategic ways to improve immediate food security and ensure livelihoods for the future. My background in soils provides a view that is invisible to many, and too-often ignored. 

How will the poor in the developing world be affected by climate change?

How to kill pests without killing yourself or the earth......

There are about 50 to 60 million insect species on earth - we have named only about 1 million and there are only about 1 thousand pest species - already over 50% of these thousand pests are already resistant to our volatile, dangerous, synthetic pesticide POISONS. We accidentally lose about 25,000 to 100,000 species of insects, plants and animals every year due to "man's footprint". But, after poisoning the entire world and contaminating every living thing for over 60 years with these dangerous and ineffective pesticide POISONS we have not even controlled much less eliminated even one pest species and every year we use/misuse more and more pesticide POISONS to try to "keep up"! Even with all of this expensive pollution - we lose more and more crops and lives to these thousand pests every year.

We are losing the war against these thousand pests mainly because we insist on using only synthetic pesticide POISONS and fertilizers There has been a severe "knowledge drought" - a worldwide decline in agricultural R&D, especially in production research and safe, more effective pest control since the advent of synthetic pesticide POISONS and fertilizers. Today we are like lemmings running to the sea insisting that is the "right way". The greatest challenge facing humanity this century is the necessity for us to double our global food production with less land, less water, less nutrients, less science, frequent droughts, more and more contamination and ever-increasing pest damage.

National Poison Prevention Week, March 18-24,2007 was created to highlight the dangers of poisoning and how to prevent it. One study shows that about 70,000 children in the USA were involved in common household pesticide-related (acute) poisonings or exposures in 2004. It is estimated that 300,000 farm workers suffer acute pesticide poisoning each year in the United States - No one is checking chronic contamination.

In order to try to help "stem the tide", I have just finished re-writing my IPM encyclopedia entitled: THE BEST CONTROL II, that contains over 2,800 safe and far more effective alternatives to pesticide POISONS. This latest copyrighted work is about 1,800 pages in length and is now being updated at my new website at .

This new website at has been basically updated; all we have left to update is Chapter 39 and to renumber the pages. All of these copyrighted items are free for you to read and/or download. There is simply no need to POISON yourself or your family or to have any pest problems.
