Resumen

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.

Resumen

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.

Resumen

<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>

Resumen

Aiming at agricultural production in a sustainable, satisfactory manner and with less impact on the environment, cultivation systems such as crop-livestock integration, crop-livestock-forest integration, direct planting systems and agroforestry have been adopted. Crop-Livestock-Forest Integration Systems allow the increase in agricultural production without the need to convert new areas to agriculture, increasing the diversification of agricultural production on rural properties and applying different scales of agricultural enterprises. Thus, crop-livestock-forest integration systems are an important alternative for the sustainable expansion of Brazilian agriculture, reducing negative environmental impacts.

Resumen

AbstractClimate change affects all segments of the agricultural enterprise, and there is mounting evidence that the continuing warming trend with shifting seasonality and intensity in precipitation will increase the vulnerability of agricultural systems. Agricultural is a complex system within the USA encompassing a large number of crops and livestock systems, and development of indicators to provide a signal of the impact of climate change on these different systems would be beneficial to the development of strategies for effective adaptation practices. A series of indicators were assembled to determine their potential for assessing agricultural response to climate change in the near term and long term and those with immediate capability of being implemented and those requiring more development. The available literature reveals indicators on livestock related to heat stress, soil erosion related to changes in precipitation, soil carbon changes in response to increasing carbon dioxide and soil management practices, economic response to climate change in agricultural production, and crop progress and productivity. Crop progress and productivity changes are readily observed data with a historical record for some crops extending back to the mid-1800s. This length of historical record coupled with the county-level observations from each state where a crop is grown and emerging pest populations provides a detailed set of observations to assess the impact of a changing climate on agriculture. Continued refinement of tools to assess climate impacts on agriculture will provide guidance on strategies to adapt to climate change.

Resumen

Sustainable and resilient systems within the food industry play a key role in global growth and development. In recent years, negative effects such as drought caused by climate change, destructive natural disasters, and destruction of biodiversity and natural resource erosion, agricultural migration, aging agricultural population, and global epidemics have deepened the environmental concerns. Apart from the negative effects on the food supply, pressure on the demand side is created by the growing population, which makes it necessary to create a new agrarian policy. Technological development has affected agriculture and agricultural production systems. One of the most prominent approaches is the integration of a new generation of digital technologies into the agricultural system, ensuring maximum benefit from information and data. Digitalization and the use of digital data have fundamentally transformed the agro-food system. The aim of this paper is present in a systematic view the agricultural digital transformation in the Agriculture 4.0, in the framework of sustainable development of agriculture. The aforementioned imposes sustainable agriculture by adequate agricultural policy instruments.

Resumen

The sustainability of our world and the ecological balance are significantly shaped by agricultural systems. The main environmental implications of agricultural practices are highlighted in this research with an emphasis on both the detrimental effects and proposed remedies to lessen these effects. By supplying food, fiber, and different raw materials, agricultural systems are essential for maintaining human populations. These systems, though, have the potential to have a significant negative or positive impact on the environment. An overview of the main environmental impacts of agricultural systems is given in this research First, agricultural systems play a significant role in the production of greenhouse gases. The release of carbon dioxide (CO2), methane (CH4), and element oxide (N2O), all of which are powerful greenhouse gases that contribute to climate change, is influenced using synthetic fertilizers, intensive livestock production, and changes in land use. Second, agricultural practices have an impact on water resources. The overuse of irrigation water can cause groundwater aquifers to be depleted and rivers and lakes to dry up. Additionally, the fertilizer and pesticide-contaminated runoff from agricultural fields can contaminate water sources, leading to eutrophication and harming aquatic ecosystems. Adopting sustainable agricultural practices is necessary to meet rising food demands while reducing adverse effects. These methods include organic farming, agroforestry, precision agriculture, and improved water management strategies. By putting such practices into practice, one can encourage a more resilient and sustainable food production system while also reducing the negative environmental effects of agriculture.

Resumen

As climate change worsens, the frequent occurrence of extreme drought events will further threaten the agricultural systems of all countries in the world. Kyrgyzstan is a country with agriculture and animal husbandry as its main industries, with a weak industrial base, and agriculture plays an important role in the national economy. Kyrgyzstan is located in Central Asia and suffers from a dry climate and frequent droughts. Thus, an integral analysis of the vulnerability of Kyrgyzstan’s agricultural system is of great significance for this country’s socio-economic stability. In this study, we comprehensively analyze the agricultural system drought vulnerability of Kyrgyzstan from three dimensions of sensitivity, adaptability and exposure. The results show that the areas of higher vulnerability in Kyrgyzstan’s agricultural system are distributed in the eastern mountainous, northwest and southwest areas. In addition, regions with low vulnerability are mainly concentrated in the central area. Kyrgyzstan has abundant water resources, but the supporting infrastructure construction is relatively backward. The imperfect irrigation facilities have greatly restricted the development of agriculture and have also increased the vulnerability of the agricultural systems. In the face of climate change, the region may face more severe drought disasters, so increasing infrastructure investment and building a complete irrigation system and water use plan are the keys to reducing the vulnerability of Kyrgyzstan’s agricultural system.

Resumen

This paper presents an agricultural management service system that aims to meet the needs of Internet of Things (IoT) information upgrades in China’s family farms. The proposed agricultural management service system consists of Near Field Communication (NFC) tags, in-field service nodes, and smartphones. NFC tags are used as the core identifier of various agricultural management elements. The in-field service node, which is based on a programmable system-on-chip with intellectual property cores (IP core), supports distributed agriculture device management and smartphone operations. Smartphones in the proposed system include the management assistant application (app) and management service app, which are designed for agricultural management support functions and agricultural management application requirements. Through this system, the needs of diverse agricultural management practices can be effectively satisfied by a unified system structure. The practical results show that the design can be used to construct diversified agricultural IoT information application service systems simply and effectively, and it is especially suitable for Chinese family farm operators who are implementing IoT information upgrades for smart agriculture.

Resumen

Cropping system diversification is a key factor in developing more sustainable cropping and food systems. The agroecological practice of intercropping, meaning the simultaneous cultivation of two or more species in the same field, has recently gained renewed interest as a means of ecological intensification in European agricultural research. We discuss some recent research developments regarding 1) intercropping for ecological intensification in agroecological and conventional cropping systems, 2) studies on nitrogen resource use by cereal-grain legume intercropping cultivation, 3) the role of intercropping in the management of biotic stressors, especially weeds, and 4) intercropping as a means of creating cropping systems that are more resilient to the abiotic and biotic stress associated with climate change. Finally, we propose methods for the greater adoption of intercropping in European agriculture by unlocking farming systems from upstream and downstream barriers, with the aim of developing more sustainable agricultural and food systems.

Resumen

Agricultural economics is a science that studies the relations of production and the laws of productivity in agriculture. International agricultural economics is to study the agricultural production relations and the laws of productivity in different regions of the world, countries with different systems, and different historical stages, especially the history and future development trends of agricultural economic development under different social systems in the East and the West, in order to learn from each other. The development of agricultural economic theory and practical experience, promote the integration of global agricultural economy, improve the status quo of global chemical agriculture, develop global modern ecological agriculture, ensure global food and food safety, and improve the health of human life.

Resumen

Beside traditional mechanical engineering, other engineering branches such as electronics, control engineering and physics play their specific role within the agricultural engineering field. Agricultural engineering has affected and stimulated major changes in agriculture. In the last decades agricultural engineering has also focused on environmental aspects. Nowadays knowledge and expertise generated in several agricultural and environmental engineering fields must be integrated with expertise of biological and socio-economic sciences. In the evolution towards sustainable agricultural systems important contributions can be made. The re-design of production systems and their technology can help to achieve ecologically sound and economically viable agriculture and its acceptance in the community. Mechanization and automation, structures and environment, labour and management, and energy and water are discussed.

Resumen

AbstractIn many respects the long standing and vigorous debates over alternative agriculture and organic farming are becoming less strident and less polarized. However, despite the mounting evidence that key elements of both the conventional and alternative agricultural communities are beginning to “build bridges” to each other, and to establish formal institutional programs and arrangements for improved communication and program development, important differences continue to separate the proponents and opponents of alternative agriculture. In part, these lingering differences result from the lack of adequate and reliable data, misinformation, and faulty data analyses. In order to clarify those issues which continue to divide the critics and advocates of alternative agriculture, this reappraisal of the debate begins with a methodological critique of comparison studies of conventional and organic farms. Also included is an assessment of fertilizer and pesticide use in American agriculture, the environmental impacts of conventional and reduced-input systems, the relationship between alternative agriculture and efforts to save the family farmer, and the prospects for increased public sector research on reduced-input farming systems.

Resumen

Information systems relate to diverse applications, but, until recently, the use of this technology in agriculture and environment has been relatively behind the applications in the industrial sector. The publication of IJAEIS started in 2010 in order to promote the new research advances in information systems applied to agriculture and environment. This paper presents an overview of the different scientific issues presented in the 50 papers published in IJAEIS between 2010 and 2013. The authors summarize the different contributions presented in IJAEIS and the authors identify the main trends in the field of agricultural and environmental information systems (ontologies, communication systems, spatial information processing, etc.).

Resumen

Agricultural teacher education programs are designed to prepare competent teachers who are ready to teach students in public schools. One aspect of agricultural teacher education is ensuring teachers are ready to lead instruction in various aspects of school-based agricultural education (SBAE), such as teaching students various technical agriculture skills. As part of a larger study, we used a three-round Delphi study to identify the technical agriculture skills SBAE teachers in Illinois and Iowa need to effectively teach courses in the Plant Systems pathway within the broader Agriculture, Food, and Natural Resources (AFNR) Career Cluster. A panel of 27 experienced SBAE teachers nominated by their colleagues contributed data for our study. Eighteen teachers participated in all three rounds. At the conclusion of our Delphi study, we identified 82 technical agriculture skills. To help ensure teachers are competent and prepared to teach courses in the Plant Systems pathway, we suggest several approaches agricultural teacher educators should consider: (1) facilitating opportunities to implement technical agriculture skill development opportunities within agricultural teacher education programs, (2) engaging with agricultural faculty who teach technical agriculture courses to pre-service teachers, and (3) using our list of 82 skills as a springboard to facilitate future scholarly inquiry on the topic. While our results are not generalizable beyond the SBAE teachers in Illinois and Iowa, we do believe our findings are valuable to SBAE stakeholders. To enhance generalizability and provide a more thorough exploration of teachers’ technical agriculture skill needs, replication of our study should occur in other states.

Resumen

Agriculture systems, which account for a sizable share of global greenhouse gas emissions, are placing a growing burden on the environment while also contributing to increasingly common health problems. Climate change is making the situation worse by reducing agricultural productivity as well as the nutritional content of certain crops, which in turn is driving intensified production to meet global food demand. To break out of this potentially catastrophic feedback loop, societies must realign agricultural policies, financial incentives, and diets to promote health and environmental sustainability.

Resumen

The paper depicts agricultural robots that can perform complex tasks. Fast development and application of agricultural robotics is a result of increased development of agricultural machinery. Robots are complex and intelligent systems with a significant role in agriculture that are becoming an integral part of both the technological and scientific progress. The paper presents some important roles of robots and robotic systems in various agricultural areas and explains the deployment of new technologies supported by the examples of their application in arable farming, horticulture, and forestry. Robotics application decreases the deployment of human resources, enables significant production cost savings, and increases production capacity. The application of robotic systems facilitates high precision levels and repetition speed regarding time and space, which cannot be replicated by farmers

Resumen

Agricultural systems science generates knowledge that allows researchers to consider complex problems or take informed agricultural decisions. The rich history of this science exemplifies the diversity of systems and scales over which they operate and have been studied. Modeling, an essential tool in agricultural systems science, has been accomplished by scientists from a wide range of disciplines, who have contributed concepts and tools over more than six decades. As agricultural scientists now consider the “next generation” models, data, and knowledge products needed to meet the increasingly complex systems problems faced by society, it is important to take stock of this history and its lessons to ensure that we avoid reinvention and strive to consider all dimensions of associated challenges. To this end, we summarize here the history of agricultural systems modeling and identify lessons learned that can help guide the design and development of next generation of agricultural system tools and methods. A number of past events combined with overall technological progress in other fields have strongly contributed to the evolution of agricultural system modeling, including development of processbased bio-physical models of crops and livestock, statistical models based on historical observations, and economic optimization and simulation models at household and regional to global scales. Characteristics of agricultural systems models have varied widely depending on the systems involved, their scales, and the wide range of purposes that motivated their development and use by researchers in different disciplines. Recent trends in broader collaboration across institutions, across disciplines, and between the public and private sectors suggest that the stage is set for the major advances in agricultural systems science that are needed for the next generation of models, databases, knowledge products and decision support systems. The lessons from history should be considered to help avoid roadblocks and pitfalls as the community develops this next generation of agricultural systems models.
