Rainfed agriculture has potential to produce needed cereals for the growing populations of West and Central Asia even though rainfed agriculture is perceived as risky. The value of rainfed agriculture to produce competitively should be re-assessed. This requires the concerted efforts of farmers, researchers, and policy makers to work on the technical factors that determine agricultural production as well as to address the economic policy environment. Syria is a small country with a diversified rainfed and irrigated agriculture. Rainfed and supplemental irrigation technology has improved Syria's food self-reliance, however, the policy environment is not conducive to the sustainable use of natural resources. Supplemental irrigation technology to produce wheat is used to illustrate the need to address both the technical issues as well as the economic incentives to make agricultural production competitive. Kazakhstan is a large country with a predominantly rainfed agriculture. Farmers could benefit from rainfall probabilities to use fertilizer and improved wheat varieties under rainfed agriculture as Syria did during the eighties and nineties. Implicit taxation of farmers needs to be removed and access to markets must be ensured for farmers in Kazakhstan to benefit from international wheat prices. While it is important to improve production technology, the economic policy environment needs to be addressed first to create incentives for farmers to produce commodities competitively in water-scarce regions.

Abstract. The challenges China faces in terms of water availability in the agricultural sector are exacerbated by the sector's low irrigation efficiency. To increase irrigation efficiency, promoting modern irrigation technology has been emphasized by policy makers in the country. The overall goal of this paper is to understand the effect of governmental support and economic incentives on the adoption of modern irrigation technology in China, with a focus on household-based irrigation technology and community-based irrigation technology. Based on a unique data set collected at household and village levels from seven provinces, the results indicated that household-based irrigation technology has become noticeable in almost every Chinese village. In contrast, only about half of Chinese villages have adopted community-based irrigation technology. Despite the relatively high adoption level of household-based irrigation technology at the village level, its actual adoption in crop sown areas was not high, even lower for community-based irrigation technology. The econometric analysis results revealed that governmental support instruments like subsidies and extension services policies have played an important role in promoting the adoption of modern irrigation technology. Strikingly, the present irrigation pricing policy has played a significant but contradictory role in promoting the adoption of different types of modern irrigation technology. Irrigation pricing showed a positive impact on household-based irrigation technology, and a negative impact on community-based irrigation technology, possibly related to the substitution effect that is, the higher rate of adoption of household-based irrigation technology leads to lower incentives for investment in community-based irrigation technology. The paper finally concludes and discusses some policy implications.

The paper discusses the economic issues of the COVID-19 pandemic. The resulting coronomic crisis is not a typical economic crisis since the coronomic crisis was not formed in the economy itself but is the result of the inability of medicine to solve the pandemic problem. The coronomic crisis is, by its very nature, an atypical economic crisis and is fundamentally different from other atypical economic crises that took place in the XX century. The coronomic crisis put the issue of the “crisis of globalization” on the agenda. The coronomic crisis exposed the weaknesses of globalization. Overcoming the COVID-19 pandemic is possible exclusively at the global level. The paper shows that the current process of de-globalization is “forced” by its nature and it will definitely be replaced by a qualitatively renewed process of globalization. Economic recovery from the corona crisis will be most successful only on the basis of the adherence to a free trade regime. In economic science, the problem of government intervention in the economy, especially during the pandemic and the post-pandemic period, is still relevant. The corona crisis has clearly confirmed the inability of inflation targeting to achieve macroeconomic stability. The coronomic crisis requires two approaches to economic policy. In particular, we mean an anti-crisis economic policy and a post-crisis economic policy. Economic incentives provided by the government to businesses contribute to the zombieing of the economy which will be one of the most difficult problems of the post-crisis period. The coronomic crisis made the issue of the economic security of each individual country even more urgent. The problem of ensuring food security is equally important. The economic policy of the post-crisis period must necessarily include measures to ensure a country’s food security. Since the possibility of a repetition of a pandemic in the future is similar to the current one, the problems of coronomics should remain in the field of study of economists for many years.

Socioeconomic Considerations

Agriculture is not only the main source of income to most Palestinian families; it is also the link to connect them to their valuable land and water resources. Farmers seek assistance from agronomists and decision makers to cultivate the proper products. In this study, the best selection of agricultural crops is addressed in the multiple-objective context. The study deals with three conflicting objective functions: net benefit, agricultural production, and labor employment. Four-stage procedure is adopted combining multiple-objective optimization, simple valuation methods, cluster analysis, and multiple criteria decision making (MCDM) methods. Pareto optimal curves are used to evaluate the marginal prices of both land area and labor day. The theories of utility and benefit cost are applied to rank the non-dominant alternatives. Two MCDM methods, namely weighted goal programming and step methods, are employed in the evaluation. The above methodology is applied to the case study of Qalqilya District in which irrigated agriculture under semi-arid conditions prevails. The results show that Pareto optimal is a powerful tool to determine the marginal price of non-monetary commodities. It is also found that the average annual net benefit, agricultural production, and labor employment for the cultivated area are $941,423, 3,288 tons, and 14,671 days, respectively, in the best compromise plan. The inclusion of socioeconomic considerations in decision making on agricultural systems is crucial for their sustainable development.

Αυτή η διδακτορική διατριβή είναι μια περιβαλλοντική συμβολή στη μετακεϋνσιανή μακροοικονομική θεωρία. Η συμβολή σχετίζεται με τη σημασία της περιβαλλοντικής/οικολογικής διάστασης, η οποία, δεν έχει κεντρικό ρόλο στη μετακεϋνσιανή βιβλιογραφία. Αρχικά, στόχος μας ήταν να διερευνήσουμε πώς το περιβάλλον επηρεάζει την οικονομική δραστηριότητα και πώς το περιβάλλον θα μπορούσε να εισαχθεί στην ανάλυση της ενεργού ζήτησης και της οικονομικής ανάπτυξης. Η εισαγωγή του περιβαλλοντικού παράγοντα υπόκειται στις αρχές οικολογικής και βιοφυσικής προστασίας που υποδεικνύουν τη βιωσιμότητα του μοντέλου. Η εισαγωγή του περιβαλλοντικού στοιχείου υλοποιήθηκε μέσω της φυσικής προσέγγισης του κεφαλαίου. Ωστόσο, ο ακρογωνιαίος λίθος του θεωρητικού μοντέλου, είναι η δημιουργία μιας μεταβλητής που αντιπροσωπεύει το μερίδιο του πράσινου κεφαλαίου στη συνολική οικονομία, και την οποία χρησιμοποιήσαμε για να εκφράσουμε το βαθμό της χρησιμοποίησης του παραγωγικού δυναμικού ως συνάρτηση του μεριδίου του πράσινου κεφαλαίου. Από αυτή την άποψη, αποδείχθηκε ότι η μετάβαση σε μια βιώσιμη οικονομία είναι ευνοϊκή για τη συσσώρευση κεφαλαίου. Η οικονομετρική ανάλυση που διενεργήθηκε για τις 28 χώρες της Ευρωπαϊκής Ένωσης παρέχει στοιχεία που επικυρώνουν τις κύριες υποθέσεις μας και ειδικότερα ότι οι επενδύσεις και η συσσώρευση κεφαλαίων ευνοούνται από τη μετάβαση σε μια πιο πράσινη οικονομία. Προχωρήσαμε επίσης στη διερεύνηση της σημασίας της πράσινης κατανάλωσης για τη μετακεϋνσιανή μακροοικονομία. Αφού παρουσιάσαμε τα βασικά χαρακτηριστικά της κατανάλωσης και της βιώσιμης κατανάλωσης, εισήγαμε το περιβαλλοντικό στοιχείο σε ένα μετακεϋνσιανό μοντέλο κατανάλωσης. Από αυτή την άποψη, χρησιμοποιήσαμε την έννοια των πράσινων ζωικών πνευμάτων (green animal spirits), συνδυάζοντας την έννοια του Κέινς για τα animal spirits, τη μετακεϋνσιανή θεωρία της γνώσης και τη θεωρία λήψης αποφάσεων του καταναλωτή, όπως προσεγγίζεται από την επιστήμη της ψυχολογίας. Συμπληρωματικά και λόγω του αυξανόμενου ενδιαφέροντος για τη βιώσιμη κατανάλωση, καθώς και του αυξανόμενου ενδιαφέροντος και των διαθέσιμων δεδομένων για το οικολογικό αποτύπωμα, παρουσιάζεται επίσης ένα μοντέλο οικολογικού αποτυπώματος κατανάλωσης. Η οικονομετρική ανάλυση παρείχε στοιχεία που επικυρώνουν τις κύριες θεωρητικές μας υποθέσεις και ειδικότερα σχετικά με τη σημασία των πράσινων animal spirits για την περιβαλλοντικά φιλική κατανάλωση. Τόσο τα θεωρητικά όσο και τα εμπειρικά μοντέλα θεωρούνται ότι συνεισφέρουν σημαντικά σε μια πράσινη μετακεϋνσιανή θεωρία της ενεργούς ζήτησης. Τέλος, παρουσιάζεται μια ανάλυση πολιτικής οικονομίας σχετικά με τη αποτελεσματικότητα των περιβαλλοντικών πολιτικών στον καπιταλισμό.

The past 15 years have been eventful ones for the Chinese economy. They have seen an ambitious attempt at economic acceleration decline into agricultural crisis, a major reversal of the direction of economic policy, agricultural recovery and resurgent economic momentum. These years have brought major changes to the Chinese economy: whole new industries have appeared; official policy towards such diverse areas as education, income distribution, regional dispersion of industry and economic specialization has shifted repeatedly; the organization of agricultural production has also changed.

Highlights Irrigation is key to the productivity of Great Plains agriculture but is threatened by water scarcity. The irrigated area grew to >9 million ha since 1870, mostly since 1950, but is likely to decline. Changes in climate, water availability, irrigated area, and policy will affect productivity. Adaptation and innovation, hallmarks of Great Plains populations, will ensure future success. Abstract. Motivated by the need for sustainable water management and technology for next-generation crop production, the future of irrigation on the U.S. Great Plains was examined through the lenses of past changes in water supply, historical changes in irrigated area, and innovations in irrigation technology, management, and agronomy. We analyzed the history of irrigated agriculture through the 1900s to the present day. We focused particularly on the efficiency and water productivity of irrigation systems (application efficiency, crop water productivity, and irrigation water use productivity) as a connection between water resource management and agricultural production. Technology innovations have greatly increased the efficiency of water application, the productivity of water use, and the agricultural productivity of the Great Plains. We also examined the changes in water stored in the High Plains aquifer, which is the region’s principle supply for irrigation water. Relative to other states, the aquifer has been less impacted in Nebraska, despite large increases in irrigated area. Greatly increased irrigation efficiency has played a role in this, but so have regulations and the recharge to the aquifer from the Nebraska Sand Hills and from rivers crossing the state. The outlook for irrigation is less positive in western Kansas, eastern Colorado, and the Oklahoma and Texas Panhandles. The aquifer in these regions is recharged at rates much less than current pumping, and the aquifer is declining as a result. Improvements in irrigation technology and management plus changes in crops grown have made irrigation ever more efficient and allowed irrigation to continue. There is good reason to expect that future research and development efforts by federal and state researchers, extension specialists, and industry, often in concert, will continue to improve the efficiency and productivity of irrigated agriculture. Public policy changes will also play a role in regulating consumption and motivating on-farm efficiency improvements. Water supplies, while finite, will be stretched much further than projected by some who look only at past rates of consumption. Thus, irrigation will continue to be important economically for an extended period. Sustaining irrigation is crucial to sustained productivity of the Great Plains “bread basket” because on average irrigation doubles the efficiency with which water is turned into crop yields compared with what can be attained in this region with precipitation alone. Lessons learned from the Great Plains are relevant to irrigation in semi-arid and subhumid areas worldwide.

Irrigation Modernization

<p>Irrigation modernization, here defined as the replacement of traditional flood irrigation systems by pressurized drip-irrigation technology, has been widely promoted with the aim to move towards a more sustainable use of freshwater resources in irrigated agriculture. However, the scale sensitivity of irrigation efficiency challenged the predominantly positive value attributed to irrigation modernization and asked for an integrated evaluation of the technological change at various scales. The aim of this study is therefore to contribute to an improved understanding of the hydrological functioning in a landscape under irrigation modernization. We used local field observations to propose a regional scale modeling approach that allowed to specifically simulate the difference in water balance as a function of irrigation method and crop type. The approach focused on the modification of the spatial input data and had therefore the benefit of being relatively independent of the final choice of the hydrological model. We applied the proposed approach to the semi-arid agricultural area of Valencia (Spain), where regional information about the use of irrigation technologies and irrigation volumes at farm level were available. The distributed hydrological model Tetis was chosen to simulate the daily water balance from 1994 to 2015 for an area of 913 km<sup>2</sup> at a spatial resolution of 200 m. Model simulations were based on a random selection of parameter values that were subsequently evaluated in a multi-objective calibration framework. Multiple process scales were addressed within the framework by considering the annual evaporative index, monthly groundwater level dynamics, and daily soil moisture dynamics for evaluation. Simulation results were finally analyzed with a focus on groundwater recharge, which is of particular interest for environmental challenges faced within the study area. Simulation results of groundwater recharge for the entire agricultural area indicated a considerable variability in annual recharge (values from 112 mm up to 337 mm), whereby recharge was strongly controlled by annual rainfall volumes. Annual recharge in flood-irrigated areas tended to exceed annual recharge in drip irrigated-areas except for years with above average rainfall volumes. The observed rainfall dependency could be explained by the fact that recharge in drip-irrigated areas almost exclusively occurred during rainy days, whereby a few heavy rainfall events could produce the majority of annual recharge. Our results indicated interesting differences but also commonalities in groundwater recharge for flood and drip irrigation, and therefore emphasized the importance of explicitly considering irrigation technology when modelling irrigated agricultural areas.</p>

The article discusses the issue of government support for reclamation activities in the context of new challenges of the economic environment. The relevance of the issue is due to the need for intensive development of the agricultural sector caused by globalization processes, which have created fierce competition, both in the international and domestic food markets. Sustainable production of agricultural products on irrigated lands is one of the main indicators of the efficiency of the agro-industrial complex in areas of risky agriculture, including the Republic of Tatarstan. The purpose of the article is to develop recommendations for improving the efficiency of irrigated agriculture whose development depends on the stability of agricultural production and food security. The study aims to identify trends in the development of land reclamation at the regional level and substantiate measures aimed to improve the economic efficiency. The paper presents results of the analysis of development of land reclamation in the Republic of Tatarstan, identifies directions of its development, provides recommendations for ensuring sustainable growth in the volume of reclaimed land and agricultural products, income from the sale of products obtained through irrigation. The research results can be used to develop programs aimed at the development of federal and regional food markets, organizational, economic, technological measures to improve the efficiency of agricultural production, rural areas and the provision of high-quality food supply to the population.
