The number of young farmers has decreased over recent decades in several developed countries such as the United States and European countries. A strategy adopted by Union to address resulting age imbalance is Young Farmer Payment which provides an additional payment on top average basic introduced last Common Agricultural Policy reform. objective this study determine, means a behavioural approach, how influenced incentives stay farm.

Abstract Sustainability in our food and fiber agriculture systems is inherently knowledge intensive. It more likely to be achieved by using all the knowledge, technology, resources available, including data-driven agricultural technology precision methods, than relying entirely on human powers of observation, analysis, memory following practical experience. Data collected sensors digested artificial intelligence (AI) can help farmers learn about synergies between domains natural that are key...
The complex interplay between agricultural and energy commodities has been a subject of interest in past research, gaining more relevance recently due to geopolitical events such as the conflict Ukraine Russia. This systematically driven up prices both commodities. Deeply understanding dynamic interconnections these cascading resulting from war is crucial for comprehensive market analysis. Our study leverages connectedness or risk spillover based on Quantile Vector Autoregression (QVAR)...
By collecting more data at a higher resolution and by creating the capacity to implement detailed crop management, autonomous equipment has potential revolutionise precision agriculture (PA), but unless farmers find profitable it is unlikely be widely adopted. The objective of this study was identify economic implications for arable using grain-oilseed farm in United Kingdom as an example. possible because Hands Free Hectare (HFH) demonstration project Harper Adams University produced grain...
Abstract Autonomous equipment for crop production is on the verge of technical and economic feasibility, but government regulation may slow its adoption. Key regulatory issues include requirements on‐site human supervision, liability autonomous machine error, intellectual property in robotic learning. As an example impact benefits equipment, analysis from United Kingdom suggests that requiring 100% supervision almost wipes out small medium farms increases economies‐of‐scale advantage larger farms.
Field size and shape constrain spatial temporal management of agriculture with implications for farm profitability, field biodiversity environmental performance. Large, conventional equipment struggles to small, irregularly shaped fields efficiently. The study hypothesized that autonomous crop machines would make it possible non-rectangular profitably, thereby preserving other benefits. Using the experience Hands Free Hectare (HFH) demonstration project, this developed algorithms estimate...
CONTEXT: Grazing enterprises employ a range of management strategies in rain-fed Australian sheep production systems, which alters both potential and profitability. This research used stochastic whole-farm simulation modelling methodology to assess the impact six different regimes on long-term profitability model farm simulated from August 1971 July 2018.OBJECTIVE: We aimed 1) compare whole productivity economics systems 2) identify factors that were driving differences between 3) determine...
This study addresses the problem of balancing trade-offs between need for animal production, profit, and goal achieving persistence desirable species within grazing systems. The bioeconomic framework applied in this takes into account impact climate risk management pastures rules on botanical composition pasture resource, a factor that impacts livestock production economic returns over time. establishes links inputs, state resource outputs, to identify optimal development strategies....
Farming systems research conducted under dryland conditions is subject to the vagaries of climate during experimental period. Whether such an experiment experiences a representative series climatic years must be examined in relation longer term record. The Cicerone Project’s farmlet was on Northern Tablelands New South Wales, Australia, investigate profitability and sustainability three different management systems: one managed typical, moderate-input (farmlet B); second which employed...
The 400m ha of grazing lands in China, mainly across the north and west country, have similar problems to those throughout steppe Mongolia, Central Asia neighbouring countries. grasslands are drier regions (50–500mm) Inner Xinjiang, Tibet, Qinghai, Gansu Sichuan, often at higher altitudes on Tibetan, Mongolian Loess Plateaus, for millennia supported livelihoods millions herders. By 2002, surveys were classifying 90% as degraded. Less than 10% considered desertified extent that replanting was...
Overgrazing has extensively degraded Chinese grasslands. A reduction in stocking rate of 30–50% below the district averages is required to increase profitability livestock production and protect vital ecosystem services such as mitigation greenhouse gases (GHG). Grazing experiments located desert steppe, typical steppe alpine meadow verified influence grazing management on production, grassland composition associated services. The experiment found lower rates ~150 SE (where sheep equivalent,...
One of the key issues in regulation crop robots is need for human supervision. Economic analysis indicates that autonomous farming potentially reduces agricultural production costs, but such costs may often become higher than conventional when constant on-site supervision required by law. However, there are cases where a level robot helps maximise profits even if it not mandated law, as field operations or inherently require frequent intervention. The objective this study to identify...
This study analysed the dynamics of international soybean market using econometric techniques and economic models to impacts US–China trade war. It considered analysis “spatial” (horizontal) price transmission during an approximately ten-year period from September 2009 May 2019 monthly time-series data. The research focused on leaders in market, namely, China, USA, EU, Brazil Argentina. Several were employed. stationarity time series was determined augmented Dickey–Fuller (ADF) unit root...
This study analyzed the asymmetric price transmission in international soybean market, using data from US (Chicago Futures), European (Rotterdam), Brazilian (Paranaguá), Argentinian (Rosario Futures and Rosario Spot), Chinese (Spot Futures) markets. The looked at between these markets over a period of almost 10 years, September 2009 to May 2019. Phillips-Perron unit root test was used determine order integration time series. Engle-Granger cointegration failed find any evidence with others...
The application of fertilisers to pastures in the high rainfall regions southern Australia has contributed large increases carrying capacity following widespread adoption practice since late 1940s. Recently, shifts worldwide demand for fertiliser inputs have lead rises cost inputs. These increasing costs significant potential ramifications on future management soil fertility and its interaction with persistence profitability sown pastures, especially during periods climatic uncertainty. A...
Abstract Autonomous machines have the potential to maintain food production and agroecological farming resilience. However, autonomous complex mixed cropping is proving be an engineering challenge because of differences in plant height growth pattern. Strip technically simplest system, but widespread use constrained by higher labor requirements conventional mechanized farms. Researchers long hypothesized that (i.e., crop robots) might make strip profitable, thereby allowing farmers gain...
Grazing enterprises on the Central Tablelands of New South Wales employ a range different strategies to manage temperate native grassland pastures common in high rainfall zone southern Australia. This paper uses stochastic whole-farm simulation modelling approach assess impact grazing system and stocking rate (SR) long-term profitability representative case-study enterprise. In particular, infrastructure costs, debt downside risk, performance are examined over 10-year planning horizon....
