Is turning food waste into insect feed an uphill climb? A review of persistent challenges
Published: 2024-04-22
Subjects: Agricultural and Resource Economics, Agricultural Economics, Entomology, Food Science, Technology and Innovation
One major hurdle for our current food system is the enormous amount of food that goes to waste. Insect farming has been proposed as a potential solution, offering one way to turn waste into agricultural resources such as livestock and aquaculture feed. In this article, we review the types of materials currently used to raise insects at commercial scales, and we examine whether those materials [...]
Yield declines and producer responses to shifting climate and economic conditions in Mexican coffee production
Published: 2023-04-06
Subjects: Agricultural and Resource Economics, Agricultural Economics, Agriculture, Environmental Sciences, Environmental Studies, Geography, Life Sciences, Nature and Society Relations, Other Environmental Sciences
Coffee’s climate sensitivity contributes to extreme production and price fluctuations. However, as coffee is a perennial crop, producers have difficulty responding to short-term market shifts. Combining historical climate, production and price data from all coffee-growing municipalities in Mexico, we examined trends of climate and coffee production and then characterized and quantified coffee [...]
The Global Forest Health Crisis: A Public Good Social Dilemma in Need of International Collective Action
Published: 2022-03-10
Subjects: Agricultural and Resource Economics, Agricultural Economics, Agricultural Science, Agriculture, Behavioral Economics, Biodiversity, Biology, Biosecurity, Botany, Economics, Entomology, Environmental Microbiology and Microbial Ecology Life Sciences, Environmental Studies, Forest Biology, Forest Management, Forest Sciences, International Relations, Life Sciences, Microbiology, Other Forestry and Forest Sciences, Other Plant Sciences, Pathogenic Microbiology, Plant Biology, Plant Pathology, Plant Sciences, Political Science, Science and Technology Studies, Social and Behavioral Sciences
Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]
Flower strips increase the control of rosy apple aphids after parasitoid releases in an apple orchard
Published: 2022-01-14
Subjects: Agricultural Economics, Agriculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Horticulture, Life Sciences, Plant Sciences
Mass releases of two parasitoid species, Aphidius matricariae and Ephedrus cerasicola, may provide an alternative measure to pesticides to control the rosy apple aphid Dysaphis plantaginea in organic apple orchards. As a proof of concept study, we tested if the presence of flower strips between apple tree rows could improve the action of three early parasitoid releases—and of other naturally [...]
Comment on ‘Carbon intensity of corn ethanol in the United States: state of the science’
Published: 2021-05-06

Scully et al [1] in their recent contribution review and revise past life cycle assessments (LCAs) of corn-grain ethanol’s carbon (C) intensity to suggest that a current ‘central best estimate’ is considerably less than all prior estimates. Their conclusion emerges from selection and recombination of sector-specific greenhouse gas emission predictions from disparate studies in a way that [...]
Agricultural Beneficial Management Practices: A Synthesis of Co-benefits, Tradeoffs, and Co-costs between Crop Yield and Non-provisioning Ecosystem Services
Published: 2020-12-17
Subjects: Agricultural and Resource Economics, Agricultural Economics, Agriculture, Life Sciences, Social and Behavioral Sciences
Although agricultural “best (or beneficial) management practices” (BMPs) first emerged to mitigate agro-environmental resource challenges, they may also enhance ‘non-provisioning’ ecosystem services. The enthusiasm for adopting BMPs partially depends on evidence that doing so will lead to agro-environmental benefits while not substantially reducing crop productivity or farmer income. We survey [...]
Desert Locust in India: The 2020 invasion and associated risks
Published: 2020-06-01
Subjects: Agricultural Economics, Agricultural Science, Agriculture, Agronomy and Crop Sciences Life Sciences, Animal Sciences, Entomology, Life Sciences, Plant Sciences, Social and Behavioral Sciences, Urban Studies and Planning, Zoology
Wind direction, often used in forecasting locust migration, indicates a non-zero probability of desert locust invasion in eastern Indian states. Apart from present controlling measures, we are additionally suggesting to be cautious about the eggs of locust as the rainfall associated with Super Cyclone Amphan has created a favorable breeding ground for the gregarious locust. Also reverse migration [...]
