The world population growth is increasing the demand for food production. Furthermore, the reduction of the workforce in rural areas and the increase in production costs are challenges for food production nowadays. Smart farming is a farm management concept that may use Internet of Things (IoT) to overcome the current challenges of food production. This work uses the preferred reporting items for systematic reviews (PRISMA) methodology to systematically review the existing literature on smart farming with IoT. The review aims to identify the main devices, platforms, network protocols, processing data technologies and the applicability of smart farming with IoT to agriculture. The review shows an evolution in the way data is processed in recent years. Traditional approaches mostly used data in a reactive manner. In more recent approaches, however, new technological developments allowed the use of data to prevent crop problems and to improve the accuracy of crop diagnosis.

AbstractAgribusinesses are investing in different forms of AI robots, as there is a lot of hope that these machines will help meet the challenges within the agricultural industry, which is to efficiently produce more food for a growing world population. AI robots are expected to enhance production, while compensating for lack of manpower, reducing production costs, taking over unattractive (risky, heavy, and dirty) jobs and reducing the burden of food production on the environment. In spite of these promises, however, AI robots for agri-food also give rise to ethical questions and concerns, which have been little researched and discussed until now. To fill this gap, we developed a research agenda for future research in this area. To do this, we opened our analysis to focus on ethics AI robots generally to specifically identify which of these issues are most relevant to agro-robots. The question we want to find an answer to is: what are the most relevant ethical questions raised about AI robots for robots developed for the agri-food sector? And which questions are not mentioned in the literature, which are particularly relevant for agro-robots? Our paper will provide an overview over the key issues and areas which deserve further elaboration to come to a more mature ethics of AI agro-robots.

Global food security is one of the most unrelenting issues for humanity, and agricultural production is not sufficient in accomplishing this. However, earlier analyses of agricultural food production barely ever bring out the contrasts associated with economic development and different climatic zones. The world population is increasing day by day and climate change will be causing more extreme weather, higher temperatures and changed precipitation. The crop contributes about 20 % of the total dietary calories and proteins globally. There is 1% annual growth in food demand in the developing regions. The developing regions (including China and Central Asia) account for roughly 53 % of the total harvested area and 50 % of the production. Although, unmatched productivity growth from the Green Revolution since the 1960s dramatically transformed world food production, benefitting both producers and consumers through low production costs and low food prices. One of the key challenges today is to replace today’s food system with new ones for better sustainability. While the Green Revolution freed essential ecosystems from conversion to agriculture, it also created its own ecological problems. Moreover productivity increase is now slow or stagnant. Attaining the productivity gains needed to ensure food security will therefore require more than a repeat performance of the Green Revolution of the past. Future demand will need to be achieved through sustainable intensification that combines better crop resistance plants, adaptation to warmer climates, and less use of water, fuel, fertilizer, and labor. Meeting these challenges will require concerted efforts in research and innovation to develop and set up feasible solutions. Necessary investment will be required to realize sustainable productivity growth through better technologies and policy and institutional innovations that facilitate farmer adoption and adaptation. The persistent lessons from the Green Revolution and the recent efforts for sustainable escalation of food systems in South Asia and other developing nations will definitely providing useful insights for the future.

Abstract Facing the increase in world population and the stagnation in available arable land there is a high demand for optimizing the food production. Considering the world-wide and ongoing reduction of the agricultural labor force novel approaches for food production are required. Vertical farming may be such a solution where plants are being produced indoors in racks, cared by robotic appliances which will be operated by specialized software. Given the multitude of parameters which determine the ideal condition, a lot of data needs to be acquired. As this data is used to adapt the entire Cyber-Physical System to a changing environment the data has to be secure and adaptations have to consider safety aspects as well. Such systems must hence be secure, safe, scalable and self-adaptable to a high degree. We present an important element for such solutions, a cloud, IoT and robotic based smart farming framework.

Political Radicalism

During the Age of Mass Migration more than four million Italians reached the United States. The experience of Italians in US cities has been widely explored: however, the study of how migrants adjusted in relation to nature and food production is a relatively recent concern. Due to a mixture of racism and fear of political radicalism, Italians were deemed to be undesirable immigrants in East Coast cities and American authorities had long perceived Italian immigrants as unclean, unhealthy and carriers of diseases. As a flipside to this narrative, Italians were also believed to possess a ‘natural’ talent for agriculture, which encouraged Italian diplomats and politicians to propose the establishment of agricultural colonies in the southern United States. In rural areas Italians could profit from their agricultural skills and finally turn into ‘desirable immigrants’. The aim of this paper is to explore this ‘emigrant colonialism’ through the lens of environmental history, comparing the Italian and US diplomatic and public discourses on the potential and limits of Italians’ agricultural skills.

In 2000, the World population was 6.2 billion; it reached 7 billion in 2012 and should reach 9.5 billion (±0.4) in 2050 and 11 billion (±1.5) in 2100, according to UN projections. The trend after 2100 is still one of global demographic growth, but after 2060, Africa would be the only continent where the population would still increase. The amount of water consumed annually to produce the food necessary to meet the needs varies greatly between countries, from about 600 to 2,500 m<sup>3</sup>/year per capita, depending on their wealth, their food habits (particularly meat consumption), and the percentage of food waste they generate. In 2000, the total food production was on the order of 3,300 million tons (in cereal equivalents). In 2019, about 0.8 billion inhabitants of the planet still suffer from hunger and do not get the nutrition they need to be in good health or, in the case of children, to grow properly (both physically and intellectually). Assuming a World average water consumption for food of 1,300 m<sup>3</sup>/year per capita in 2000, 1,400 m<sup>3</sup>/year in 2050, and 1,500 m<sup>3</sup>/year in 2100, a volume of water of around 8,200 km<sup>3</sup>/year was needed in 2000, 13,000 km<sup>3</sup>/year will be needed in 2050, and 16,500 km<sup>3</sup>/year in 2100. Will that much water be available on earth? Can there be conflicts related to a food deficit? Some preliminary answers and scenarios for food production will be given from a hydrologist viewpoint.

The 19Th Century

The ship-rolling problem is a subject that has been studied for a long time. Since Froude's time (in the 19th century) to nowadays, this subject was revisited several times in order to adjust the theory to changes in ship hulls, dimensions, materials, appendages, etc. On the other hand, ship analysis technological resources, including both experimental techniques and computational capacity (that did not exist in Froude's time), have also amazingly improved. But despite all those technological developments, the assessment of the nonlinear roll damping of some types of hulls still is a challenging problem. The floating production storage and offloading (FPSO) hull fitted with larger bilge keels, for instance, has behaved in such a way that it is impossible to obtain results from nowadays industry standards via decaying tests. This paper discusses an alternative way to assess the nonlinear damping behavior of FPSO hulls with large bilge keels. Since it is fairly easy to perform decaying tests, the paper also proposes an alternative way to analyze the FPSO properties through this kind of testing by grouping multiple results instead of using only a single test. This artifice brought improvements, such as an increased agreement between the alternative model and the experimental data. The paper also compares the more traditional approaches with the alternative method and finally shows the latter's applicability.

Biophysical System

A sustainability framework based on nested adaptive socio-ecological systems is used to analyse historical examples of soil erosion and its implications for food production and security for a growing population. While there are examples of innovation in agriculture to address food availability, there are also cases of inadequate social responses leading to famine. The analysis highlights the value of considering these issues in a framework of linked biophysical and socio-economic systems. The socio-economic system generates management interventions to resolve biophysical limitations such as soil depletion on food production. The socio-economic system is also responsible when there are inadequate social responses. Currently, the biophysical system produces enough food to feed the world population. However, food distribution through the socio-economic system results in increasing numbers of undernourished people. Biophysical system modelling indicates that unless major changes are made to the current world system, overshoot because of resource depletion will lead to system collapse within the 21st century. To develop sustainability strategies, we need to analyse the socio-economic response to this biophysical vulnerability. A socio-ecological analysis also indicates that perspectives based on power relations that govern real-world decision making rather than sustainability interventions to address food security, need to be incorporated.

In 2007-2008 the world food crisis has substantially aggravated. This is a good reason to ponder over the fate of our technological civilization and a reminder of the finite nature of the resources used by the mankind. These resources include minerals, land suitable for cultivation, water and, at last, the technologies for securing the growing world population with the foods. The crisis has opened the eyes of many enthusiasts of the scientific and technological progress to some of its bitter fruits, in particular, to the polarization of food production and consumption, hunger and poverty of millions human beings, environmental pollution, progressive exhaustion of resources. Still, there are enough reasons to be optimistic. Earth's civilization has survived many turning points and has always found the way out and the methods to resolve the problem. It may be hoped that the humanity will also found the way out from the maze of problems that showed up as a result of the food crisis, at least in the foreseeable future.

Purpose The purpose of this paper is to produce a high-quality measure of the nature of healthcare resources available in China’s Township Health Centers (THCs), paying particular attention to equity between high- and low-income areas. Design/methodology/approach This study makes use of data from a nearly nationally representative survey in rural China conducted by the Center for Chinese Agricultural Policy at the Chinese Academy of Sciences in 2011. The samples of towns were selected randomly from 25 counties located in five provinces from different regions of China. Data were collected through questionnaires and direct observation. Findings The THCs located in rich areas have higher levels of human resources than poor areas. THCs in rich areas also have more fixed assets than those in poor areas. In fact, even though the Chinese Ministry of Health mandates that all THCs have certain basic levels of medical equipment and facilities, many THCs in poor areas do not have them. The allocation of mandated equipment is unequal. Practical implications These findings suggest that China’s government should pay more attention to THCs located in poor areas, especially in light of new initiatives to improve health care in poor rural areas. Originality/value This is the first nationally representative study to employ rigorous empirics to investigate the extent of inequality in allocation of resources within THCs across China.

Abstract. This paper argues that the interplay of water, carbon and vegetation dynamics fundamentally links some global trends in the current and conceivable future Anthropocene, such as cropland expansion, freshwater use, and climate change and its impacts. Based on a review of recent literature including geographically explicit simulation studies with the process-based LPJmL global biosphere model, it demonstrates that the connectivity of water and vegetation dynamics is vital for water security, food security and (terrestrial) ecosystem dynamics alike. The water limitation of net primary production of both natural and agricultural plants – already pronounced in many regions – is shown to increase in many places under projected climate change, though this development is partially offset by water-saving direct CO2 effects. Natural vegetation can to some degree adapt dynamically to higher water limitation, but agricultural crops usually require some form of active management to overcome it – among them irrigation, soil conservation and eventually shifts of cropland to areas that are less water-limited due to more favourable climatic conditions. While crucial to secure food production for a growing world population, such human interventions in water–vegetation systems have, as also shown, repercussions on the water cycle. Indeed, land use changes are shown to be the second-most important influence on the terrestrial water balance in recent times. Furthermore, climate change (warming and precipitation changes) will in many regions increase irrigation demand and decrease water availability, impeding rainfed and irrigated food production (if not CO2 effects counterbalance this impact – which is unlikely at least in poorly managed systems). Drawing from these exemplary investigations, some research perspectives on how to further improve our knowledge of human–water–vegetation interactions in the Anthropocene are outlined.
