Significance This study provides insights for wheat breeding efforts, public policy, and agricultural decision making related to climate change. Our findings provide opportunities the international community intensify research efforts increase resistance heat stress during focused developmental stages. These could result in net positive warming effects since reduced exposure freeze was found be a yield-enhancing benefit of warming. results indicate that advancements come at expense higher...
Agriculture is faced with the challenge of providing healthy food for a growing population at minimal environmental cost. Rice (Oryza sativa), staple crop largest number people on earth, grown under flooded soil conditions and uses more water has higher greenhouse gas (GHG) emissions than most crops. The objective this study was to test hypothesis that alternate wetting drying (AWD--flooding then allowing dry down before being reflooded) management practices will maintain grain yields...
Rice blast (Magnaporthe oryzae) is a key concern in combating global food insecurity given the disease responsible for approximately 30% of rice production losses globally-the equivalent feeding 60 million people. These increase price and reduce consumer welfare security. staple crop more than half world's population so any reduction would have substantial beneficial effects on livelihoods. In 2012, researchers US began analyzing feasibility creating blast-resistant through cisgenic...
Future increases in global surface temperature threaten those worldwide who depend on rice production for their livelihoods and food security. Past analyses of high-temperature stress have focused paddy yield failed to account the detrimental impact high temperatures milling quality outcomes, which ultimately determine edible (marketable) market value. Using genotype specific data six common varieties from Arkansas, USA, combined with on-site, half-hourly daily observations, we show a...
CRISPR gene-editing has major implications for agriculture and food security. However, no studies have evaluated the public acceptance valuation of CRISPR-produced food. As such, we conducted a multi-country assessment consumers’ willingness-to-consume (WTC) willingness-to-pay (WTP) compared to conventional genetically modified (GM) foods, respectively. In USA, Canada, Belgium, France, Australia, 56, 47, 46, 30, 51% respondents, respectively, indicated they would consume both GM We also...
Understanding extreme weather impacts on staple crops such as wheat is vital for creating adaptation strategies and increasing food security, especially in dryland cropping systems across Southern Africa. This study analyses heat using daily information a dataset 71 cultivars 17 locations South Africa from 1998 to 2014. We estimate temperature yields extensive regression models, finding that drives yield losses, with an additional 24 h of exposure temperatures above 30 °C associated 12.5%...
Both cisgenesis and transgenesis are plant breeding techniques that can be used to introduce new genes into genomes. However, uses gene(s) from a non-plant organism or donor is sexually incompatible with the recipient while involves introduction of crossable—sexually compatible—plant. Traditional could possibly achieve same results as those cisgenesis, but would require much larger timeframe. Cisgenesis allows breeders enhance an existing cultivar more quickly little no genetic drag. The...
Sustainable agricultural intensification (SAI) practices can help meet current and future food security needs while decreasing environmental impacts. To date, no studies have simultaneously estimated the implications of previously adopted rice regimes. Thus, our study analyzes impacts associated with two major in Bangladesh: (1) planting multiple seasons (2) replacing traditional (TYV) High Yielding Varieties (HYV). Bangladeshi production data by growing season variety were gathered for...
Improving the sustainability of rice production is important given rice's position as a global staple food and its relatively large environmental footprint. The Sustainable Rice Platform (SRP) initiative aims at increasing adoption sustainable practices in globally. We assess Nigerian consumers' perceptions SRP indicators using Best-Worst Scaling approach to rank attributes according their preference shares examine effects demographic characteristics purchasing habits on these shares....
Bacterial Panicle Blight (BPB), caused by Burkholderia glumae, is a bacterial disease in rice (Oryza sativa) that reduces yield and quality for producers consequently creates higher market prices consumers. BPB the simultaneous occurrence of high daily minimum temperatures (~22°C) relative humidity (~77%), which may increase under current scenario global warming. This study hypothesized economic damage from warming cause an losses, though at decreasing rate per degree. Thus, this estimates...
As water becomes scarcer in rice ( Oryza sativa L.) production regions throughout the world, producers are becoming aware of importance increasing use efficiency. Thus, new methods which increase efficiency (WUE) beginning to be adopted. This study analyzes one such alternative method and its economic feasibility Arkansas. Alternate wetting drying (AWD) irrigation has potential address concerns groundwater depletion as well greenhouse gas emissions (GHG) associated with production. Field...
Due to its genetic similarity with commercial rice, red rice is one the most damaging weeds in direct seeding systems. Using an integrated approach estimate economic, environmental, and food security impact of infestation U.S. as empirical case study, we find that losses under a moderate scenario from 2002 2014 amount 5.7 million tons or 6%, environmental cost $457 million. The resulting production loss enough feed 12 additional people year. We extend these findings selected Asian countries...
White maize in South Africa is the only staple crop produced on a widespread commercial basis for direct human consumption using genetically modified (GM) cultivars. Using combined economic and environmental approach, we estimate total welfare benefits attributable to GM white 2001–2018 are $694.7 million. Food security also manifest through an average of 4.6 million additional rations annually. To achieve these annual conventional hybrid maize, land required would range from 1088 ha 2001...
Conservation agriculture seeks to reduce environmental degradation through sustainable management of agricultural land. Since the 1990s, research has been conducted using remote sensing technologies; however, few previous reviews have focused on different conservation practices. Most literature application in without focusing exclusively practices, with some only providing a narrative review, others biophysical for quantitative estimates bio-geo-chemical-physical properties soils and crops,...
