Nigeria needs biotechnology to weather climate change impacts on farming, say West African scientists

"...“Evidence of climate change on agriculture in Nigeria has since been established and increased atmospheric warmness, irregular rainfall, emergent pests, [crop] diseases…and their resultant adverse effect on agricultural productivity are glaring,” the authors write in the November 2021 Handbook of Climate Change Management. “This scenario poses a serious threat to food security in Nigeria and calls for the adoption of innovative biotechnologies to create resilient crops with improved adaptation to the environmental stresses occasioned by the increasing climate change. ”..."

Gene editing: Powerful tool for managing climate change

"...Recently, I joined a dispersed team of researchers — Sarah Evanega, Modesta Abugu and Wilson Horner — in seeking to understand just how impactful gene editing can be in addressing climate change in agriculture. Looking broadly and deeply into the literature of gene editing applications in crops and livestock we uncovered a beautiful array of successful gene edits. Our review of the literature in this field, published in Frontiers in Sustainable Food Systems,  revealed four key points:..."

Soil Health Can Positively Affect Farm Revenue JSTOR Daily

"...The authors suggest that farms can diversify their crops to increase soil fertility, or even mix livestock and crops. In turn, a more diverse ecosystem is more likely to be resilient to the many issues farmers face today and in the future, like climate change, evolving markets, and land degradation. In future studies, the researchers want to increase the length of the dataset to see if these findings are true over time..."

Cutting food waste alone won't solve world's nutritional needs

"..."When thinking about food system sustainability, it's important to consider all aspects of sustainability: environmental, economic, social, health and nutritional," said Smith. "And nutrition doesn't just mean enough energy--it has to be the right foods, the right balance of nutrition. "..."

New study shows never before seen nutrient exchanges between algae and bacteria

"...The study reveals the details of important nutrient exchanges between algae and bacteria. Such exchanges determine the functioning of microbial communities in the environment, relevant to climate change cycles and agricultural productivity. Microbial interactions within microbial communities are important on many levels, ranging from the ecology of aquatic and terrestrial food webs, to wastewater treatment..."

Turn problems into opportunities: Photorespiration for improved plant metabolism

"...In today's plants, photorespiration dissipates some of the energy produced by photosynthesis and releases CO2. It begins when the enzyme RuBisCO acts on oxygen instead of carbon dioxide and creates toxic side-products requiring costly recycling reactions. The detoxification process uses up fixed carbon and wastes energy, thus strongly limiting agricultural productivity..."

Climate change cut global farming productivity 21% since 1960s

"...Now, a new study provides these insights: "Anthropogenic Climate Change Has Slowed Global Agricultural Productivity Growth," published in Nature Climate Change, was led by economist Ariel Ortiz-Bobea, associate professor in the Charles H. Dyson School of Applied Economics and Management at Cornell..."

UMD helps quantify how climate change has slowed global agricultural productivity growth

"..."Our study suggests climate and weather-related factors have already had a large impact on agricultural productivity," says Robert Chambers, professor in Agricultural and Resource Economics (AREC) at UMD and an esteemed agricultural productivity researcher. "We used the model in this paper to estimate what total factor productivity patterns would have looked like in the absence of climate change. "..."

Plantwise plant clinics help promote sustainable crop pest management in Rwanda and Zambia

"...Dr Justice Tambo, lead author of the study published in the journal Food Policy, surveyed 1,474 farm households in Rwanda and Zambia and found that although farmers who visit plant clinics show a higher probability of opting for pesticides for pest control, they do not use them intensively and are more likely to adopt safer and more sustainable alternatives..."

CABBI researchers challenge the CRP status quo to mitigate fossil fuels

"...As the world warms and its population explosively expands, global demand for food production is at odds with the decreased agricultural productivity threatened by extreme climate conditions. Therefore, allocating CRP land for high-yielding energy biomass might eliminate the need for bioenergy crops and food crops to vie for space..."

GMOs: Scarecrow and the irony of a farmer’s hoe

"...GM foods are developed and marketed because there is a perceived advantage to either the producer or consumer or both. This advantage often translates into a product with a lower price, longer shelf-life, lower production costs, higher nutritional value, better yields, pest-resistance, drought-tolerance, etc..."
