AbstractModern agriculture has done an excellent job producing food, feed and fiber for the world's growing population, but there are concerns regarding its continued ability to do so, especially with the world's limited resources. To adapt to these challenges, future agricultural systems will need to be diverse, complex and integrated. Integrated agricultural systems have many of these properties, but how they are shaped by the environment and how they shape the environment is still unclear. In this paper, we used commonly available county-level data and literature review to answer two basic questions. First, are there environmental limitations to the adoption of integrated agricultural systems? Second, do integrated agricultural systems have a lower environmental impact than more specialized systems? We focused on the Great Plains to answer these questions. Because of a lack of farm-level data, we used county-level surrogate indicators. The indicators selected were percent land base in pasture and crop diversity along a precipitation gradient in North Dakota, South Dakota, Nebraska and Kansas. Evaluated over the four-state region, neither indicator had a strong relationship with precipitation. In the Dakotas, both percent pasture land and crop diversity suggested greater potential for agricultural integration at the mid-point of the precipitation gradient, but there was no clear trend for Kansas and Nebraska. Integrated agricultural systems have potential to reduce the impact of agriculture on the environment despite concerns with nutrient management. Despite advantages, current adoption of integrated agricultural systems appears to be limited. Future integrated agricultural systems need to work with environmental limitations rather than overcoming them and be capable of enhancing environmental quality.

Digital agriculture is the perfect integration of digital technologies in crop and animal management and other agricultural processes. For farmers, digital farming offers the opportunity to increase production, save long-term costs and eliminate risk. Agricultural researchers see it as a data collection tool that has the ability to simplify data collection and analysis, improving predictive skills when it comes to crop management, animal behavior and production. A digital agricultural system is a database that includes not only different types of data relevant to agriculture, from soil conditions to market assessment, but also optimal decision-making functions that help to take the best measures in a series of processes. The paper presents a brief summary of new technologies in agriculture.

<p class="p1">Sustainable development is based on ethical principles such as respect for and harmony with nature, political values such as participative democracy and social equity, and moral norms such as environmental rationality. Sustainable development is egalitarian, neutral, and self-managed, able to satisfy the basic needs of people, respecting cultural diversity, and improving the quality of life. The concepts of agriculture and sustainable development refer to the need of minimizing degradation of fertile land, while working to increase production. They include agricultural activities such as soil and water management, crop management, and the conservation of biodiversity, taking into account the provision of food and raw materials. Sustainability of agricultural production systems refers to the capacity of the system to maintain its productivity in spite of economic and natural, external or internal limitations. Sustainability is a function of the natural features of a system and the pressures and interventions it experiences, as well as social, economic, and technical interventions that are carried out in order to fight negative pressures, highlighting the resiliency of the system. </p>

Come molti altri settori produttivi, anche l'agricoltura deve affrontare una crescente dipendenza energetica da elettricità, petrolio e gas naturale. Tuttavia, l'agricoltura può rispondere direttamente a tali richieste ricorrendo alle fonti di energia rinnovabili (FER), come il solare fotovoltaico (PV) e gli impianti biogas/biometano (BP). Questi sistemi sono stati fortemente incentivati in passato. Gli attuali sistemi d’incentivazione prevedono invece sussidi commisurati alle caratteristiche aziendali come stalle, fienili, disponibilità di biomasse, ecc. Per questi motivi, per quanto riguarda il settore FV, è necessario utilizzare modelli analitici affidabili per valutare l’orientamento e la tecnologia migliore, in particolare per generatori integrati architettonicamente. Per la produzione di biometano, gli impianti di piccole dimensioni risultano quelli maggiormente incentivati previa alimentazione con sottoprodotti agro-industriali. Tuttavia, le loro performance dipendono fortemente dalla tecnologia d’upgrading. Pertanto, le prospettive economiche offerte da questi sistemi RES sono legate alla scelta della tecnologia da impiegare e non più esclusivamente al semplice dimensionamento. Su questa base, l'obiettivo principale di questo lavoro è stato lo sviluppo di strumenti di supporto decisionali (DSSS) per l'ottimizzazione energetica d’impianti FV e BP. Un primo studio si è focalizzato sull’analisi prestazionale per singolo componente e globale d’impianti FV installati in un’azienda agricola. Inoltre, una procedura analitica di ottimizzazione dei parametri d’impianto è stata definita per massimizzare il rendimento elettrico di un generatore integrato architettonicamente rispetto ad un’installazione a terra. Attraverso una serie d’informazioni tecnico-economiche di tecnologie di upgrading, un secondo studio è stato condotto con l'obiettivo di sviluppare un DSS per valutare la marginalità sul reddito aziendale data dall’installazione on-farm di un impianto BP collegato alla rete del gas naturale. I risultati dei due studi hanno dimostrato come questi DSS possono essere utili strumenti per valutare preventivamente le diverse potenzialità offerte da impianti FV e BP in base alle caratteristiche di un’azienda agricola.
Like many other productive sectors, even agriculture must tackle an increasing energy dependency on electricity, petroleum and natural gas. Nevertheless, agriculture can directly respond to such request thanks to renewable energy systems (RES) like solar photovoltaic (PV) and biogas/biomethane (BP) plants. These systems have been strongly incentivized in the past. On the contrary, current incentive schemes provide feed-in-tariffs proportionate to farming characteristics as stables, barns, biomass availability, etc. For this reason, as regards the PV sector, it is required to use reliable analytical models for assessing the best orientation and technology, in particular for architecturally integrated generators. For the biomethane production, small-medium plants have stronger incentives in particular using agro-food by-products as feed. However, their performances are strongly dependent on biomethane upgrading technology. Thus, the economic prospective offered by these RES systems are substantially tied to technology choice optimization and no longer solely in simple sizing. On this basis, the main goal of this work is to develop Decision Support Tools (DSSs) for energy optimization both for PV and BP plants. A first study was focused on the analysis of PV plants installed in the same farm. The aim is to examine the impact each plant component has on the PV generator global efficiency and define an analytical procedure for technical parameters optimization in order to maximize the electric yield of an architectonically integrated plant compared to a ground-mounted one. Based on the economic and efficiency features of a biomethane upgrading technology set, a second study was carried out with the aim to design a DSS to assess enterprise-wide profit margins resulting from the on-farm BP plant installation linked to the natural gas grid. The results of the two studies have shown how these DSSs can be useful tools for choosing PV and BP technologies based on farm characteristics.

In the Western Australian agricultural region, an area of approximately 14 million hectares (70,000 square miles), widespread areas of native vegetation have been cleared and replaced with annual cropping systems, predominantly wheat. Only 1.3 million hectares (10%) of small and scattered native vegetation remnants remain. By 2000 16% of land in the region was at risk from soil salinity and was largely unproductive for commercial agriculture. A new hydrological equilibrium affecting 33% of the Western Australian agricultural region is predicted to be reached between 2050 and 2300. The starting premise of this dissertation is that normal disciplinary science was adopted as the dominant intellectual influence on natural resource management policy and thus natural resource degradation was treated as a problem for science, extracted from its social, economic and historical contexts. The second premise of this dissertation is that natural resource problems are not isolated scientific or technical problems, and are exacerbated by human failure to predict the complex inter-relationships among the social, ecological and economic systems. This dissertation initially provides an analytical narrative on the Western Australian agricultural region between 1889 and 2003 (114 years) with the main finding being that in the years pre-1970 a development-driven Western Australian Government was responsible for extensive land clearing for agriculture, often contrary to scientific advice. In the 1980s and 1990s the severity and extent of soil salinity and the prognosis of future negative trends in other natural resource indicators caused a rapid proliferation and evolution of Federal and State policies designed to 'solve the problem'. Nonetheless many natural resource problems remain intractable. The second part of the dissertation investigates the epistemology of the normal science paradigm as it was applied to natural resource management problems in the 20th century as a potentially contributing cause. The evolution of an alternative epistemology, post-normal science paradigm, is then examined for explicating our current understanding of 'reality'. A research framework was constructed which defines the post-normal science paradigm; the systemic approach; the bodies of theory-organisational, ecology, resilience and system dynamics theory; the social-ecological system perspective; and the methods-resilience analysis and system dynamics. This framework provides a novel way in which to gain a greater understanding of the fundamental or root causes of natural resource management problems. Using the case study of the Western Australian agricultural region a dynamic model was constructed based on descriptive information. An examination of the historical events and processes of the Western Australian agricultural region reveals that over a 114-year history it has evolved through two interactions of the adaptive cycle. Further investigation reveals these two cycles were synchronous with the second and third economic long-wave cycles or Kondratiev Cycles, that show the behaviour over time of the evolution of modern industrial societies. The model suggests that the reasons for the dynamic behaviour of the Western Australian agricultural region lie in the interaction of the three production growth drivers of the international commodity system, which have resulted in a pathological system, the 'Lock-in Trap'. Increased total commodity production, reinvestment and declining prices in real terms have tended to produce the unintended negative impacts of resource decline, environmental pollution and rural population decline. I suggest that the expansion of thresholds through the reinvestment in technology is a principle reason why there has not yet been a profound collapse of exploited renewable resources in the Western Australian agricultural region. Regional natural resource management strategies will need to take account of not only spatial cross-scale issues, in particular the linkages between the individual farmer and the international commodity system, but also the temporal variables, in particular the slowly emerging changes in ecological/physical variables, such as the hydrological cycle. This research can help to provide the information and heuristic metaphors to encourage natural resource policy makers to take long-term and whole system perspectives. It includes a powerful set of tools for communicating dynamic processes in an integrated method to inform policy and management decisions. The ideas in this interdisciplinary research are essential for making science relevant within a social and ecological context.

Grassland and farmland degradation is considered as one of the worst environmental and economic threats for China. The degradation process negatively affects food and water security, economy, society and climate changes. Photovoltaic water pumping (PVWP) technology for irrigation is an innovative and sustainable solution to curb the grassland degradation. At the same time it can promote the conservation of farmland, especially in remote areas of China. The combination of PVWP technology with water saving irrigation techniques and sustainable management of the groundwater resources can lead to several benefits. These include enhancing grassland productivity, halting wind and rainfall erosion, providing higher incomes and better living conditions for farmers. This doctoral thesis aims to bridge the current knowledge gaps, optimize system implementation and prevent system failures. This work represents thus a step forward to solve the current and future nexus between energy, water and food security in China, using PVWP technology for irrigation. Models for the dynamic simulations of PVWP systems, irrigation water requirements (IWR) and crop response to water have been presented and integrated. Field measurements at a pilot PVWP system in Inner Mongolia have been conducted to analyse the reliability of the models adopted. A revision of the traditional design approaches and a new optimization procedure based on a genetic algorithm (GA) have been proposed to guarantee the match between IWR and water supply, to minimize the system failures and to maximize crop productivity and thus the PVWP system profitability and effectiveness. Several economic analyses have been conducted to establish the most cost effective solution for irrigation and to evaluate the project profitability. The possible benefits generated by the PVWP system implementation have been highlighted, as well as the effects of the most sensitive parameters, such as forage price and incentives. The results show that PVWP system represents the best technical and economic solution to provide water for irrigation in the remote areas compared to other traditional water pumping technologies. The environmental benefits have been also addressed, evaluating the CO2 emissions saving achievable from the PVWP system operation. The assessment of the feasible and optimal areas for implementing PVWP systems in China has been conducted using spatial analysis and an optimization tool for the entire supply chain of forage production. The results show that the potentials of PVWP systems in China are large. Nevertheless, the feasible and optimal locations are extremely sensitive to several environmental and economic parameters such as forage IWR, groundwater depth, and CO2 credits that need to be carefully taken into account in the planning process. Although this doctoral thesis has used China as case study, PVWP technology can be applied for irrigation purposes all over the world both for off- and on-grid applications leading to several economic and environmental benefits.

Agricultural landscapes provide our society with many benefits. While food production is the primary role of these landscapes, sociocultural and ecological benefits are also provided. However, the full scope of benefits that we obtain from agricultural landscapes are not always taken into account, and with the intensification of agricultural activities, more complex multifunctional landscapes are converted into simpler and less-functional landscapes. I used a heterogeneous agricultural landscape, the Champlain Valley of Vermont, as a case study to examine the interactions between landscape structure and the provision of landscape functions and services. I analyzed sociocultural and production functions indices obtained via standardized landowner surveys, and ecological function indices collected in the field for 51 plots. Plots were clustered into landscape composition categories (forest, mixed and agriculture), and configuration categories (simple and complex). I identified a tradeoff between the production and ecological function in agricultural landscapes. When a rural landscape was managed for intensive agricultural production, ecological benefits decreased. Landscapes with diversified land use/land cover and heterogeneously distributed elements returned the greatest number of benefits. Agricultural areas that comprise between 30 and 45% of the landscape can prevent the loss of ecological benefits while retaining high production. I evaluated the importance of treed habitats in agricultural landscapes in maintaining biodiversity. I related landscape metrics to ecological function indices obtained from fine-grained land use/land cover maps. Metrics obtained from fine-grained maps more accurately predicted the abundance of edge tolerant birds than those obtained from coarse grained maps. I also explored the importance of small treed landscape elements for common breeding birds and evaluated the convenience of monitoring nests comparing temperature loggers to direct observations. More heterogeneous landscapes, rich in small treed elements, supported a greater density of nests. Nests located on small treed elements in agricultural landscapes were as successful as nests located in large landscape elements. These analyses deepen our knowledge about the relationship between landscape structure and function, facilitating the evaluation of the functionality of heterogeneous agricultural landscapes.

Ensuring the spatial development of regional agricultural systems in Ukraine during martial law requires a comprehensive study and implementation of urgent effective tools and mechanisms. The hostilities had a negative impact on agriculture, disrupting the regional structure of agricultural production and consumption, destroying agricultural land, assets, enterprises in certain regions of Ukraine, and reducing the volume of agricultural exports through traditional logistics channels. The aim of the study is use territorial marketing to ensure the development of regional agricultural systems in Ukraine. It is based on the analysis of regional structure of agricultural systems in Ukraine, clustering of regional agricultural systems in terms of relative security of sustainable agriculture, and mechanisms of land use development. The regional structure of agricultural systems in Ukraine is analyzed and the territories where the ecosystem is destroyed and unsuitable for agriculture, which are temporarily occupied are identified. The dynamics of planted area of agricultural crops under the harvest were assessed, clusters of regional agricultural systems of Ukraine during martial law were identified. Based on research results, the use of territorial marketing is proposed, a mechanism for sustainable agriculture and strategic land use planning is developed. Prospects intend to ensure spatial development of regional agricultural systems in Ukraine during martial law by relocating agricultural enterprises to relatively safe regions, creating of integrated entrepreneurial agricultural structures, developing of public-private partnerships, attracting investments and introducing innovations, digitalization in agriculture, developing exports within the framework of cross-border cooperation, increasing employment in agriculture due to internal migration processes, etc.

This study describes the typology of family agricultural systems from the western part of Romania. Fourteen family agricultural farms from Arad County, Romania, are taken in the study, whose areas range between 0.34 ha and 25 ha, with an average of about 22 ha. The main crops within these farms are grain maize, followed by wheat, oats, sunflower and rapeseed and, on smaller areas, fodder, vegetables and triticale. Because the structure of the crops is very diverse - the largest area is 12.60 ha and the smallest one is 0.07 ha , these agricultural holdings are not financially profitable because they do not allow farmers to practice intensive agriculture: soil works are performed with non-performing machines, a lot of time and fuel are lost with these works, and yield is low, which leads to decreased production and increased costs of establishment, maintenance and harvest. In conclusion, a solution for the efficiency of this agricultural system is an association of farmers and the merging of these lands, taking into account that family farming system is quite common on the territory of Romania.

In sub-Saharan-Africa (SSA), agriculture land-use supports the livelihoods of the majority of people. Land- use for agricultural-activity is an economic-activity that is highly dependent upon weather and climate that produce food and fibre necessary to sustain human life. Hence, land-use for agriculture is expected to be vulnerable to climate variability. This paper examines this relationship. The paper presents data and generated evidence-based decision making under risk and uncertainty as influenced by climate change and its effects on agricultural land-use/outputs. Farm-level cost-route survey of cross-sectional national-data of 800 respondents was used for analysis. Data were analyzed and presented using the tools of descriptive statistics, trans-logarithms model and multivariate probit model (MVP). The study indicated a strong relationship between efficient use of agricultural-land and adaptive-processes to climate-change. Thus, providing data and analysis that strengthen policy decisions on land-use and climate change. Hence, policies of promoting and motivating sustainable land-use management need to be entrenched.

In the 21st century, agriculture is different from what it was before, as agricultural technology is being transformed and progress does not stand still. Farmers moved from manual labor to machine labor. For example, in the world of agricultural technology and machinery, there are various machines for harvesting crops, cultivating fields, etc., for example, a combine harvester for harvesting wheat and other crops, a machine for harvesting fruits and vegetables, various tractors for cultivating soil, and machines and unmanned aerial vehicles (UAVs) to control weeds and pests that plague farmers. The article provides an overview and comparison of new and old agricultural technologies and prospects for their further development.

As the population increases, urbanization will gradually reduce the area of cultivated land, and the pressure on the agricultural system will continue to increase. In traditional agriculture, there is a reliance on mechanical operations, with manual harvesting as the basis, resulting in high costs and low efficiency. Quality control of agricultural products helps to judge and determine the quality of products and promotes their commercialization. With the development of computer vision technologies, automatic sorting and quality control of agricultural products has been achieved, and computer vision systems have been widely used in various areas of agricultural and food production market segments, avoiding the high cost and low efficiency of traditional operations.

Public and private investments in alternative food production systems have increased in recent years. Two systems, controlled environment agriculture (CEA) and agrivoltaics (AV), have been highlighted for their potential to provide socioeconomic benefits beyond food production. This study examines recent innovations in the production process for CEA and AV systems, the extent to which they have been adopted, whether these are providing output for agricultural markets, and the types of crops or other agricultural goods the systems supply. There have been growing investments in these alternative food production systems, both for commercial and research purposes. But the growth opportunities also come with economic, technical, and other challenges, which are examined in this report.

Over the last century, agriculture has evolved from a labor-intensive industry to one that uses mechanized, high-powered production systems. The introduction of robotic technology in agriculture could be a new step towards labor productivity. By mimicking or extending human skills, robots overcome critical human limitations, including the ability to operate in harsh agricultural environments. In this context, in 2014 the development of the first agricultural robot in Mexico (“Voltan”) began at Chapingo Autonomous University. The research’s objective was to develop an autonomous multitasking vehicle for agricultural work. As a result of this development, a novel suspension system was created. In addition, autonomous navigation between crop rows was achieved through computer vision, allowing crop monitoring, fertilizer application and, in general, pest and disease control.

Resumo:

Autonomous agricultural vehicles are entering the marketplace, performing jobs that current equipment cannot do or are too dangerous for humans to perform. They offer the prospect of greater farm productivity, and they will help to feed the world’s growing population. This report looks at several topics that impact the commercial success of autonomous agricultural vehicles. The economic benefit that an autonomous system brings to a farm will be discussed alongside machine utilization rates, job quality, and labor savings. The need for standards and regulations to help promote the development of safe systems—as well as to define the language around autonomous agriculture—is also considered. Additionally, this report will highlight the importance of reliability in agricultural machinery and how successful commercialization of autonomy will depend on the ability to do the job correctly and consistently. A critical part of commercial success is how the autonomous agricultural vehicle fits into existing farm processes to provide a complete solution for the farmer. It is hoped that this report will help developers interested in commercializing autonomous agricultural vehicles consider more than just the technical problems to solve and make choices beneficial to market adoption.
