Land Rental Market and Agricultural Production Efficiency: A Bayesian Perspective

Исследования Уральского НИИСХ и опыт передовых хозяйств Свердловской области показывают, что для повышения эффективности и стабильности кормопроизводства необходимо в структуре кормовых культур увеличивать удельный вес высокобелковых, высокоэнергетических и засухоустойчивых культур, производить подсев многолетних трав ежегодно на площади не менее 60 тыс. га, а в перспективе 7080 тыс. га. За последние 7 лет (20112018 годы) площади люцерны в области увеличились в 2 раза (до 23 тыс. га), кукурузы по зерновой технологии в 2,4 раза (до 20,9 тыс. га) и масличных культур в 3,1 раза (до 30,8 тыс. га). Опыт СПК Килачёвский Ирбитского района показывает, что освоение научно обоснованных биологизированных севооборотов, прошедших изучение в стационарных опытах Уральского НИИСХ, позволяет ежегодно получать высокие и стабильные урожаи всех сельскохозяйственных культур. В этом хозяйстве каждая кормовая культура размещается в своём севообороте. В СПК Килачёвский и ряде других хозяйств Свердловской области большое значение придаётся возделыванию люцерны, кукурузы и масличных культур. Площадь этих культур в расчёте на одну корову мы назвали белковоэнергетическим коэффициентом (БЭК). Анализ показал тесную взаимосвязь между белковоэнергетическим коэффициентом и молочной продуктивностью. Так, в СПК Килачёвский в 2016 году при удое 10196кг БЭК был равен 1,25 в 2017 году удой достиг 10798кг, БЭК 1,43 в 2018 году соответственно 11493 кг и 1,47 при количестве коров 29002977 голов. According to the investigations conducted at the Ural Agricultural Research Institute and experience of the leading farms in the Sverdlovsk region high effectiveness and stability of Forage Production requires wide cultivation of droughtresistant crops rich in protein and energy as well as seeding over 60 thousand ha (in the future 7080 thousand ha) by perennial grasses annually. For the last 7 years (20112018) areas of alfalfa increased by 2 times (up to 23 thousand ha), grain maize by 2.4 times (up to 20.9 thousand ha), oil crops by 3.1 times (up to 30.8 thousand ha). SPK Kilachevskiy (agricultural production cooperative) reported that the use of approved crop rotations tested at the Ural Agricultural Research Institute resulted in annual high and stable yields of all the crops. SPK Kilachevskiy and other farms of the region widely grow alfalfa, maize and oil crops. Land area for the cultivation of these crops per one cow is called proteinenergy coefficient (PEC). Proteinenergy coefficient was shown to have a significant correlation with milk productivity. SPK Kilachevskiy reported that in 2016 PEC and milk yield reached 1.25 and 10196 kg in 2017 1.43 and 10798 kg in 2018 1.47 and 11493 kg, respectively under 29002977 cows.

Abstract A coordinated nexus of agricultural resources is vital to achieve food security and sustainable development in China. Comprehensively considering the water–energy–food nexus as well as the external environment, this study adopts a three-stage data envelopment analysis (DEA) modelling evaluation method to assess the agricultural production efficiency (APE) of seven provinces in the middle and lower reaches of the Yangtze River (MLYR) during 1996–2015. The results show that the three-stage DEA modelling evaluation method reveals real APE and is considered to be a better quantitative method than conventional approaches. A gradually widening range of APE is an important challenge for this region. Significantly, this region generates huge demands for agricultural resources. Moreover, regional emissions of greenhouse gases (GHG) decreased from 34.20 million tons standard coal in 1996 to 32.11 million tons standard coal in 2015, though APE has continued to decrease by 2.56% in the past two decades. In general, the management and technology levels should be improved simultaneously, even though specific opportunities for APE improvement vary across provinces in MLYR. However, understanding the temporal and spatial variation of APE along with the WEF nexus from a production-based insight is a vital step toward appropriately targeted policy making for nationwide resources savings and emissions reduction.

Resource Environment

Climate change and farmland environmental pollution have put greater pressure on the sustainability of agricultural production. Based on the provincial panel data of mainland China from 1978 to 2018, climate variables such as precipitation, temperature, and sunshine hours are included into the input indicators, and agricultural non-point source pollution and carbon emissions are taken as undesirable outputs, the agricultural production efficiency (APE) under the dual constraints of climate change and the resource environment was estimated by the super slacks-based measure (SBM)-undesirable model. On the basis of the trajectory of the imbalanced spatiotemporal evolution of APE shown by Kernel density estimation and the standard deviational ellipse (SDE)–center of gravity (COG) transfer model, the spatial convergence model was used to test the convergence and differentiation characteristics of APE. Under the dual constraints, APE presents a “bimodal” distribution with a stable increase in fluctuation, but it is still at a generally low level and does not show polarization, among which the APE in the northeast region is the highest. The COG of APE tends to transfer towards the northeast, and the coverage of the SDE is shrinking, so the overall spatial pattern is characterized by a tendency of clustering towards the north in the north-south direction and a tendency of imbalance in the east-west direction. APE has significant spatial convergence, and there is a trend of “latecomer catching-up” in low-efficiency regions. The introduction of spatial correlation accelerates the convergence rate and shortens the convergence period. The convergence rate is the highest in the central and western regions, followed by that in the northeastern region, and the convergence rate is the lowest in the eastern region. In addition, the convergence rate in different time periods has a phase change. The process of improving the quality and efficiency of agricultural production requires enhancing the adaptability of climate change, balancing the carrying capacity of the resource environment, and strengthening inter-regional cooperation and linkage in the field of agriculture.

The Subject

The use of alternative systems seeking unsustainability in agricultural production in Brazil, has developed strongly with the use of No-Tillage System (NTS), therefore remodeling the production system. For the production efficiency, it is necessary to use suitable crops as plant cover, depending on the region where the no-tillage system will be set, in which sorghum and millet crops were very positive. Thus, the objective of the work is to perform a systematic literature review on papers approaching the subject with the use of sorghum and millet as a vegetative cover for subsequent no-tillage. It is possible to verify a concentration of the studies after the 2000 decade, in the Southeastern and Central-Western regions of Brazil.

Control Of Corruption

This paper examines the association between controls of corruption and the agricultural production efficiency of 23 European Union Member States during the recent economic crisis. Production efficiency, measured in terms of technical efficiency, is the effectiveness of a given set of inputs that is used to produce an output. Owing to climate and geographical location agriculture in European countries is diverse. The economic downturn led by the financial crisis which started in mid-2007, is still prevailing across European countries. Control of corruption along with the existing economic crisis of the member states are affecting agriculture production efficiency. This study used the national level production data for the period of 2003-2009. It shows that the technical efficiency of most Member States have declined over the years and that it was significantly lower in austere economic crisis time 2007-09 than 2003-06 for all countries. It is also found that the declining trend of technical efficiency is significantly lower for central and eastern European countries than for the western European countries. Study finds that the control of corruption in the presence of high government effectiveness, decreases the technical efficiency of agricultural production in the Member States.Res. Agric., Livest.
