Research is Critical to Preventing the Next Pandemic

By Dr. Tim Kurt a Scientific Program Director at FFAR

The COVID-19 pandemic in humans is caused by a virus that originated in bats, likely passed through an intermediate species and has now infected at least two house cats and eight exotic big cats at the Bronx Zoo. This does not mean that you should immediately quarantine your pets; the Centers for Disease Control and Prevention has more information about keeping you and your pets safe. This news prompts numerous questions about the science behind diseases that spread from humans to animals, a class of diseases known as zoonoses. The COVID-19 pandemic has laid bare the reality that human and animal health is interconnected and that cross-species transmissions can have devastating global health consequences, making it imperative that we invest in research to prevent future incidents.

Zoonotic diseases are far more common than you might think. In my lifetime, and I’m not quite 40, the world has witnessed several outbreaks of zoonotic diseases including HIV/AIDS, which crossed from chimps to humans in the 1920s in Africa but wasn’t identified until 1981. The Nipah virus was detected in Malaysia in 1998 and spread to humans from bats via infected pigs. More recently, the Severe Acute Respiratory Syndrome (SARS) spread from bats or civet cats to humans in 2002, avian influenza emerged from poultry in Asia in 2003, and swine flu, first detected in Mexico in 2009 was a combination of bird, pig and human influenza viruses. And don’t forget Middle Eastern Respiratory Syndrome (MERS), which has been linked to camels and was first detected in Saudi Arabia in 2012. Genetic sleuthing suggests that Ebola, which spread across Africa in recent years, likely jumped from bats or nonhuman primates to humans. It is still unclear which wildlife species may be susceptible to COVID-19, or what might happen if the virus recombines with naturally occurring coronaviruses in those species – an unsettling knowledge gap.

I got my start studying another major group of zoonotic diseases that includes mad cow (a prion disease), which jumped from cows to humans in 1996. As a veterinary scientist, I studied the mechanisms underlying susceptibility to cross-species transmission of this group of diseases. One of the discoveries I found most disconcerting – albeit fascinating – was that some pathogens can change dramatically upon transmission to a new species. This means that, in some cases, the pathogen can become infectious to new hosts, depending on their genetic background, making it extremely challenging to predict the movement of diseases between and across human and animal populations. We may be witnessing this same phenomenon in COVID-19, as the virus is widely believed to have originated in bats, crossed to an intermediate host, and has now spread rapidly to infect millions of humans globally.

The Foundation for Food and Agriculture Research (FFAR) builds public-private partnerships to fund audacious research addressing the biggest challenges in food and agriculture, including epidemic diseases. In response to COVID-19, FFAR is supporting Veterinary Fellowships to conduct zoonotic disease and agricultural productivity research, including economic modeling to bolster the food supply and producers during crises. Limited funding exists to support experiential learning opportunities in the agricultural sciences for future veterinary scientists. To meet this critical unmet need, FFAR is waiving the matching requirement for the FFAR Veterinary Fellows program this year, as we believe that training the next generation of veterinary scientists to predict, prevent and respond to pandemics like COVID-19 is critical for the U.S. food and agriculture community.

Cross-species, multi-disciplinary research is important to preventing and responding to current and future pandemics, while also providing the peace of mind that our food supply is safe and secure. The public relies on farmers and ranchers for safe and affordable food; the least we can do is support farmers and ranchers, and the public, with the best science we can offer.

Overcoming Water Scarcity

Overcoming Water Scarcity

Continue

Agriculture uses 70 percent of the world’s accessible freshwater. FFAR’s 2016-2018 Overcoming Water Scarcity Challenge Area addressed water use efficiency in agriculture by developing water conservation and reuse technologies, improving crop and livestock breeds, creating improved agronomic practices, increasing the social and economic tractability of conservation practices and enhancing the efficacy of Extension services.

FFAR’s Sustainable Water Management Challenge Area builds on earlier work to increase water availability and water efficiency for agricultural use, reduces agricultural water pollution and develops water reuse technologies.

FFAR’s 2016-2018 Healthy Soils, Thriving Farms Challenge Area increased soil health by building knowledge, fueling innovation, and enabling adoption of existing or new innovative practices that improve soil health.

The Soil Health Challenge Area advances existing research and identifies linkages between farm productivity and soil health, while also addressing barriers to the adoption of soil health practices.

Protein Challenge

Protein Challenge

FFAR’s 2016-2018 Protein Challenge Area sought to improve the environmental, economic and social sustainability of diverse proteins.

The Advance Animal Systems challenge area supports sustainable animal production through environmentally sound productions practices and advancement in animal health and welfare. Additionally, the Next Generation Crops Challenge Area develops non-traditional crops, including plant-based proteins, and creates new economic opportunities for conventional crops to increase future crop diversity and farm profitability.

Food Waste and Loss

Food Waste and Loss

About 40 percent of food in the US, or $161 billion each year, is lost or wasted. FFAR’s 2016-2018 Food and Waste Loss Challenge Area addressed the social, economic and environmental impacts from food waste and loss through research that developed of novel uses for agricultural waste, improved storage and distribution, supported tracking and monitoring, minimized spoilage through pre- and post-harvest innovations and changed behaviors to reduce food waste

FFAR’s current Health-Agriculture Nexus Challenge Area addresses food waste and loss and supports innovative, systems-level approaches to reduce food and nutritional insecurity and improve human health in the US and globally.

Forging the Innovation Pathway to Sustainability

Continue

Supporting innovation is necessary for sustainable results. Over the last 50 years, farmers have tripled global food production thanks to agricultural innovations. Forging the Innovation Pathway to Sustainability was a 2016-2018 Challenge Area that focused on understanding the barriers and processes that prevented the adoption of technology and research results into sustainable practices.

Urban Food Systems

The 2016-2018 Urban Food Systems Challenge Area addressed feeding urban populations through urban and peri-urban agriculture and augmenting the capabilities of our current food system.

The Urban Food Systems Challenge Area continues this work and enhances our ability to feed urban populations.

Making My Plate Your Plate
