Dr Rod Greder | Developing Innovative Tools to Incentivise Sustainable Cattle Ranching

Dr Rod Greder | Developing Innovative Tools to Incentivise Sustainable Cattle Ranching

Small, seemingly minor annoyances can be the final hurdles standing in the way of a good idea. Dr Rod Greder, a rancher and researcher, experienced this first-hand when studying cattle farms. Some best practices for pasture-based cattle production can be time-intensive, deterring many farmers from making the shift. Moreover, we still lack reliable scientific data that can be presented to farmers to demonstrate the economic advantages of pasture-based practices, such as intensive rotational grazing. To incentivise more farmers to make the transition to this more sustainable form of raising cattle, Dr Greder has created simple, cost-effective tools that make managing and monitoring pastures more profitable and sustainable for the rancher.

Dr Christine Sprunger – Tackling Soil Health from Every Angle

Soil health is fundamental to feeding the growing human population and mitigating the most damaging effects of global climate change. Despite its importance, the complex and dynamic nature of soil means that best practices for protecting and restoring Earth’s soil are not always available. By bringing together different fields and employing innovative new techniques, Dr Christine Sprunger and her team at The Ohio State University are gaining insights on how to improve soil health and tackle some of our planet’s biggest threats.

Complementing Plant Breeding Programs with Biotechnology

Complementing Plant Breeding Programs with Biotechnology

There are three components that impact crop harvests: the genetics of the seed sown, the environment in which the crop is grown, and the inputs employed during the growing period. For most species, the genetic component is addressed through breeding programs. Breeding programs require genetic variation within the available crop population from which parental crosses are made. Breeding programs that develop elite cultivars for commodities such as maize, soybean, wheat and sorghum, have wonderful inherent genetic diversity to utilise. However, many desired traits that breeders seek are not present within existing crop populations. It is here where the tools of biotechnology can complement plant breeding programs, by introducing novel pieces of genetic variation that can impart these favourable traits.

Dr Keerti Rathore – Bioengineered Cotton Could Help Solve World Hunger

Dr Keerti Rathore – Bioengineered Cotton Could Help Solve World Hunger

Humans have relied on cotton’s textile fibre for nearly seven millennia. However, utilising cottonseed as food has been a long and unfulfilled goal of many plant breeders. Along with its abundant, high-quality protein, cottonseed also contains gossypol – a toxic chemical that renders the seed inedible. Cottonseed’s fate as a mostly unusable by-product seemed sealed until Dr Keerti Rathore, a professor at Texas A&M University, announced that he had successfully created gossypol-free cottonseed. Dr Rathore’s tireless devotion has given the world the potential to significantly improve food security worldwide.

Dr Dennis Busch | Dr Andrew Cartmill – Agricultural Research Today for a Better Future Tomorrow

How to support the expanding human population is one of the greatest societal challenges in the 21st century. To meet the demand for food, fuel and fibre, agricultural productivity will need to dramatically increase. However, to ensure long-term sustainability and resilience, increased productivity must not sacrifice the health of the surrounding ecosystems. Led by Dr Dennis Busch and Dr Andrew Cartmill, the University of Wisconsin-Platteville’s Agro-Ecosystem Research Program draws on the expertise of local and international collaborating scientists and farmers to develop alternative agricultural practices that support sustainable intensification for future food security.

Dr Kenneth Johnson – Fighting Fire Blight in Organic Orchards

Dr Kenneth Johnson – Fighting Fire Blight in Organic Orchards

The bacteria that causes fire blight in apple and pear trees is notoriously difficult to control without antibiotics. With new regulations in the US preventing antibiotic use in organic orchards after 2014, organic farmers faced an impossible choice – lose their organic certification or risk the death of their trees. Working against the clock, plant pathologist Dr Kenneth Johnson from Oregon State University accelerated his efforts to provide organic farmers with another option. With his team of researchers and outreach specialists, he developed and evaluated non-antibiotic management strategies for fire blight in organic apple and pear orchards.

Dr Marlyse Leng – Creating Nutritious Baby Food from Local and Affordable Produce

Dr Marlyse Leng – Creating Nutritious Baby Food from Local and Affordable Produce

Malnutrition, occurring as either a lack of food or not eating enough of the right types of food, is a significant concern in many African countries, particularly for children. To address this issue, Dr Marlyse Leng and her colleagues at the University of Douala in Cameroon have recently developed a nutritious weaning food for infants, made from an endangered yam species to increase its production and use. After processing the yam with other key nutrients into an optimised formulation, they explored the food’s nutrient availability and antioxidant activity in comparison to other products.

Building Community Resiliency through Horticultural Innovation

Building Community Resiliency through Horticultural Innovation

Food insecurity directly impacts a third of the world’s population and perpetuates a cycle of hunger and malnutrition that is inherited through generations. Previous relief efforts have largely been donor-focused, providing only temporary solutions. To break the cycle of food insecurity, poverty, and hunger, relief efforts must empower communities and facilitate real transformative changes. Professor James Simon of Rutgers University and colleagues have developed a transferable horticulture model that builds upon local ecosystem knowledge and cultural infrastructures while embedding science-driven, market-first, and value chain methodologies. Introduced into several countries in sub-Saharan Africa, the model includes agribusiness and technical skills training to strengthen the participation of farmers and local entrepreneurs, particularly women and youth, in profitable value chains. Using this novel approach, the Rutgers team and their African colleagues have successfully demonstrated how horticulture can contribute to a real reduction in poverty and malnutrition, while fostering job creation, pride and creativity.

Genetically modified crops can offer a range of environmental and health benefits, such as reduced usage of chemical pesticides, improved farm efficiency and crop yields, and an enhanced nutritional profile. Despite this, fears surrounding genetic modification have led to a lack of acceptance of these foods by many consumers, regulators, and governmental organisations. Dr Richard Goodman from the Food Allergy Research and Resource Program at the University of Nebraska–Lincoln, is helping to shift the narrative around genetically modified crops, through his extensive work evaluating their safety.

Dr James Simon – A Breakthrough in the War Against Basil Downy Mildew

Dr James Simon – A Breakthrough in the War Against Basil Downy Mildew

Sweet basil is among the most popular and economically important culinary herbs, but by 2010, US production began to feel the impact of a newly emerging destructive disease: basil downy mildew. At that time, no sweet basil varieties were resistant to basil downy mildew and growers began relying heavily on fungicide application to avoid devastating crop losses. Dr James Simon at Rutgers University had been researching basil for 25 years and was eager to tackle this problem. Eight years later, Dr Simon’s team is proud to have successfully developed 12 new downy mildew resistant varieties of sweet basil and two varieties resistant to fusarium wilt disease.
