Leafroll disease is one of the most important virus diseases grapevines worldwide. It reduces yields, delays fruit ripening, soluble solids, and increases titratable acidity in juice. This study uses a net present value (NPV) approach over 25-year lifespan vineyard to examine economic impact grapevine leafroll (GLRD) on <i>Vitis vinifera</i> cv. Cabernet franc Finger Lakes vineyards New York. identifies optimal control options under several scenarios prevalence, yield reduction, quality...
Abstract Agriculture faces key challenges of increasing productivity while reducing adverse impacts on the environment. Conventional practices that rely tillage, inefficient and over‐application chemicals, monoculture row cropping are leading to growing resistance weeds pests nutrient sediment run‐off, declining soil carbon stocks in United States. Digital technologies artificial intelligence (AI) enabling collection vast amounts geo‐referenced information about conditions within field,...
Grapevine leafroll disease (GLRD) is a devastating viral found across all grapegrowing regions. Vineyard managers have adopted various strategies for managing GLRD, including roguing individual symptomatic vines and replacing them with certified derived from clean, virus-tested stocks; applying insecticides targeting mealybug vector populations to reduce spread minimize long-term impacts; fully replanting vineyards at the onset of symptoms. Moreover, some elect not control GLRD all. We...
The indirect impact of climate change on agriculture through diseases and pests is understudied. However, estimating the direct impacts separately necessary for selecting adaptation strategies based direction magnitude each channel. We investigate relative contribution in context coffee leaf rust, crop's most damaging disease. construct a farm-level bioeconomic model assess projected warmer temperatures more prolonged droughts expected net present values four farm types Colombia: sun...
Abstract Grapevine leafroll disease threatens the economic sustainability of grape and wine industry in United States around world. This viral reduces yield, delays fruit ripening, affects quality. Although there is new information on spatial‐dynamic diffusion, little known about profit‐maximizing control strategies. Using cellular automata, we model diffusion for individual plants a vineyard, evaluate nonspatial spatial strategies, rank them based vineyard expected net present values....
Pathogen-tested foundation plant stocks are the cornerstone of sustainable specialty crop production. They provide propagative units that used to produce clean planting materials, which essential as first-line management option diseases caused by graft-transmissible pathogens such viruses, viroids, bacteria, and phytoplasmas. In United States, efforts produce, maintain, distribute pathogen-tested material crops spearheaded centers National Clean Plant Network (NCPN). Agricultural economists...
Abstract Several indigenous tribes around the world derive spiritual value from revering fauna and flora species. Species conservation is not a prime objective of such traditions but can be an unintended consequence. Conventional species practices ignore this are often evicted protected areas. We use existence framework to develop coupled ecological-economic model non-use, values wildlife for tribe that derives population. calibrate Biligiri Rangaswamy Temple (BRT) Tiger Reserve in India...
Abstract The heavy reliance on herbicides for weed control has led to an increase in resistant weeds the United States. Robotic is emerging as alternative technology removing mechanically using artificial intelligence. We develop integrated ecological and economic dynamic (I‐WEED) model examine biophysical drivers of adopting robotic management simulate optimal timing intensity adoption within across growing seasons. specify a cohort‐based growth that relates yield damages effective density...
Spotted wing drosophila (SWD) is an invasive pest with devastating effects on soft‐skinned fruit crops. Due to its high economic impacts, current SWD management strategies usually focus preventive calendar‐based insecticide sprays. The industry calling for adoption of monitoring‐based integrated (IPM) reduce unnecessary applications. However, because traps are costly and do not provide perfect observations the population size, most growers monitor. We develop a Bayesian state‐space...
We propose a novel, distance- and density-dependent specification of externalities that captures spatial dynamics within between neighboring land parcels. use this to model the short- long-distance diffusion control an infectious disease in two privately owned ecologically connected vineyards. Using computational experiments generate individual aggregate payoffs, our results suggest ignoring within-parcel may overestimate social cost externality. find increased resource value heterogeneity,...
BACKGROUND: The potential of Origanum syriacum L. to become a cultivated crop in Lebanon rather than being harvested from the wild was investigated at production, postharvest and economic levels. Three irrigation schemes were tested on growth parameters oregano plants. In order identify most quality-preserving drying technique, air-, oven (30 °C)- freeze-dried samples assessed through sensory analysis. Cost/benefit analysis used compare O. four production scenarios. RESULTS: An scheme 16 L...
Abstract Certified organic farming is a suite of regulated practices that can support social, economic, and ecological sustainability in agriculture. Despite the standardization regulation certifying bodies, adopted by farmers vary with potential heterogeneous effects on environmental outcomes. While it accepted beliefs enable or constrain adoption practices, remains unclear if variation farmer mediates observed heterogeneity ecology farms. Communities soil microorganisms induce plant...
Rapid advances and diffusion of artificial intelligence (AI) technologies have the potential to transform agriculture globally by improving measurement, prediction, site-specific management on farm, enabling autonomous equipment that is trained mimic human behavior developing recommendation systems designed autonomously achieve various tasks. Here, we discuss applications AI-enabled in agriculture, including those are capable on-farm reinforcement learning key attributes distinguish them...
We investigate how phytosanitary regulations related to apple maggot could affect optimal pest control strategies and profits for producers potentially located in quarantine areas. estimate producer by an orchard's status subject a regulation requiring additional cold storage period, reflecting the import requirements of China British Columbia (Canada). Interestingly, we find that increased cost burden generated from areas has unintended consequence raising number chemical applications,...
Abstract Research on ecosystem services (ES) is heavily concentrated ecological and economic indicators values, with a much more limited understanding of communities’ dependence cultural ES. That body research also typically focused current generations generates insights into the intergenerational dynamics ES dependence.
