This research examines the transformation of the agro-climatic conditions of the Altai region as a result of climate change. The climate of the Altai region in Russia is sharply continental and characterized by dry air and significant weather variability, both in individual seasons and years. The current study is determined by the lack of detailed area-related analytical generalizations for the territory of the Altai region over the past 30 years. Most of the published data dealing with an integrated analysis of the agro-climatic conditions in the Altai region date back to the late 1960s and early 1970s; in most cases, this data is from climate reference-books based on the generalized data from the first half of the 20th century. To make accurate forecasts and to efficiently manage agricultural production in the Altai region, area-related data on the state and dynamics of agro-climatic changes have been analysed. The results reveal that in the period between 1964 and 2017, significant climatic changes occurred in the territory of the Altai region. These climatic changes affected the growing season length, which increased due to a shift in the dates of the air temperature transition above 10 °C, to earlier dates in spring and to later dates in autumn. Furthermore, the current study also revealed that the foothills of the Altai Mountains are the most moistened parts of the region and the Kulunda lowland is the most arid part. In the Altai region, the accumulated temperatures and amounts of precipitation during the growing season increased significantly, and the values of integrated coefficients and indices that reflect the moisture supply conditions for the territory also changed significantly. Based upon the results, a schematic map of the current precipitation distribution on the Altai region’s territory has been generated. These results and this map may be used to conduct more detailed studies in the field of agro-climatology and to update the current borders of agro-climatic areas and revision of the agro-climatic zonation scheme.

In this paper we analyse vertical price transmission in two typical Italian wheat chains, the pasta and bread chains, that were particularly affected by strong market fluctuations during the last years. After having split the chains into two sides, upstream (farm–wholesale) and downstream (wholesale–retail), we apply a cointegration methodology allowing for the presence of potentially unknown structural breaks. Then, for the different subperiods detected by the break dates, we investigate the evolving price transmission elasticities finding evidence of asymmetric price transmission. In the pasta chain, farmers seem to be price-takers, while in the bread chain price transmission is related to market structure and to the coexistence of small and large retailers. Full article

The determinants of large-scale land acquisitions (LSLAs) are, in most cases, outside the traditional sales–buying land market, as they are often rented lands for long periods of time or exploitation licenses. Sub-Saharan Africa is among the most affected regions by this phenomenon for reasons related to its land policy, and includes 37% of the total LSLAs cases. The paper develops an econometric model based on a logarithmic OLS regression to identify the determinants of LSLAs in sub-Saharan Africa. As suggested by the literature, this analysis poses the total agricultural area acquired by country as dependent variable. Results show that investors prefer a country offering a sufficiently free trade economic context with a good level of agricultural productivity, thus allowing an easy investment process. Moreover, a country with a formal recognition of land rights is preferred, to have guarantees on their investment. The availability of water is also one of the main LSLAs drivers, as a natural limit of agricultural investments. Full article

Concerns about the functioning of food supply chains have been raised by the European Commission over past years, calling for more effective and coordinated action by National Competition Authorities (NCAs). To fill this knowledge gap, an equilibrium displacement model is used to screen conduct along the supply chain, combining the advantages of asymmetric price transmission (APT) studies and structural models. The test was carried out on the Italian fluid milk supply chain following market monitoring action by the NCA. Three periods (1996–2003; 2000–2008 and 1996–2008) have been examined, finding imperfect competition over 1996–2008 and 2000–2008, while no conclusions may be drawn over the time span 1996–2003. In the testing process, the model’s peculiarities and certain limitations emerged, and related suggestions for its improvement are discussed. This approach may be used as a preliminary “fast” test for competition policy screening, as a complement to other methodologies. However, further theoretical and empirical model validation is necessary. Full article

Sustainable production besides economic, energetic, and environmental aspects should consider social and cultural features of the territory in which it relies. This occurs above all for agriculture that is intrinsically related to the territory. Today, the territory as a landscape represents a complex eco-system (subjects, communities, traditions, cultures, and specific agricultural systems) and a valuable vehicle for art and history and it is also a strategic asset to defend and promote with environmental policies. The topic of urban preservation and regeneration has been increasing by opening up to other factors such as the engagement of local communities and the contribution they can give toward the development of the identity and the symbolic universe of every community especially for historic territories. The main research question of this study is: Can historic territories be described as the landscape of a complex eco-system able to support a new cultural policy? In addition, which type of connections between physical resources and the virtual-cultural ones of that landscape are strategic assets for promoting historic territories? This theoretical manuscript is oriented toward improving territorial policies. In more details, it tries to develop a new model to reach a “global community of creativity” as a bridge between the networks of historic territories, which is meant as roots of variety to transfer to future generations, and between local and global quality in an emergent landscape. In order to reach this new model, the local community and ecosystem capabilities require a multi-level connection among both art, science, and culture as well as nature, technology, and civic capability. The result is that the new model is able to share common goods, which are both internal and external. Following this path, it is urgent to develop policies in an emergent perspective that are able to combine artistic, ecological, environmental, and cultural assets. In particular, the goals are to: (i) explore the complex value of territorial contexts that develop/evolve from both a medium-term and long-term point of view that is not described by Gross Domestic Product (GDP) standard indicators, (ii) reach the suggestion of a continuous re-articulation of sectors of knowledge proposed by cultural resources, and (iii) highlight that cultural marketing is involved in the interpretation and transmission within a large network of participants, users, institutions, markets, virtual, and territorial places. The starting point is identified as the landscape of historic territory, but an important achievement will be to transfer the main results to other territories by studying specific case histories of urban and non-urban landscapes.

Humankind currently consumes more resources than our planet is able to generate. In our web survey, we investigated insects and earthworms, as a possible future food source. We targeted the survey to university students, as the possible future consumers and trendsetters of new food. A total of 3556 university students (18–29 years old) completed it. The aims of this study were to evaluate participants’ food preferences and their willingness to taste foods containing terrestrial invertebrates. Data were processed using Cronbach’s alfa to assess the reliability of each constructs. The food preferences showed pizza-focaccia and pasta at the highest rankings, followed by fruit and vegetables. Males have a higher preference for any kind of animal protein source. Gender influenced food preference and willingness to eat food with insect or earthworm ingredients. The results indicated that students were prone to consider novel food into the Italian diet and to familiarize with them in the future. Insects/earthworms were more accepted in salty snacks. Highlighting the essential amino-acids daily requirements of a snack with earthworm meal did not improve the willingness to taste it. Information and awareness of future global food demand can play a fundamental role in accepting new food. Full article

A field experiment was conducted in Astaneh-ye Ashrafieh of Guilan Province in northern Iran to evaluate the environmental impact of peanut (Arachis hypogaea L.) production under three levels of nitrogen (N) use (0, 30, and 60 kg ha⁻¹) applied in the form of urea fertilizer. Six categories of environmental impact (i.e., global warming potential, acidification potential, terrestrial eutrophication potential, depletion of fossil resources, potassium resources, and phosphate resources) were determined. The functional unit was assumed the production of one ton of peanut pod yield. Peanut pod yield increased by 48.8% with N rate 30 kg ha⁻¹ and by 108.6% with N rate 60 kg ha⁻¹, compared with control (without N fertilization). The environmental index (EcoX) values with regard to global warming, acidification, and terrestrial eutrophication potential were 0.18, 0.52, and 0.66 for N rates of 0, 30, and 60 kg ha⁻¹, respectively. Increase in N rate aggravated the emission of NH₃ and N₂O, resulting in more harmful effect of peanut growth on the environment at higher N rates than control (without N fertilization). The resources depletion index (RDI) values with regard to depletion of fossil resources, potassium resources, and phosphate resources were 0.80, 0.53, and 0.30 for N rates of 0, 30, and 60 kg ha⁻¹, respectively. Increase in N rate and the resultant higher peanut yield mitigated the environmental effects of fertilization mainly by reducing the depletion of phosphate resources. Proper N input is a major consideration for mitigating environmental impacts of N fertilization in crop production and producers should be informed to use the least rate that will give them an economic optimum return over the long run.

Sustainable development is more often considered by media, public opinion, and politicians to be the main goal our society should attempt to pursue in the coming years. To this aim, academic researchers have made sustainability one of the main objects of their studies. This work focuses on environmental sustainability and presents a brief overview of how it is taken into consideration in the agricultural economics field by considering this topic from different perspectives and thus highlighting how this field is gradually broadening its scope to include sustainable development objectives. Our analysis shows that the path towards sustainable development is strongly correlated to the protection of the environment. Therefore, agricultural policies aimed at protecting and preserving the environment, and, more in general, innovation along the agri-food chain, together with consumer attention towards environmental issues, can play an important role in achieving this objective.
