Factors Affecting the Adoption of Agricultural Mechanization Technologies by Women Farmers in the Karaga District of Ghana

Labour-saving or mechanization technologies have become the driving force behind modern agriculture, yet adoption of these technologies remains low in many parts of the developing world, particularly among female farmers in Ghana. This study aims to investigate the factors that hinder the adoption of agricultural mechanization technologies by female farmers in the Karaga District of the Northern Region of Ghana. This region is known for its large agricultural lands and significant role in commercial farming. The research was conducted using qualitative research methodology and involved interviewing 60 female farmers using an interview guide. The principle of sample saturation was used, meaning that further interviews were deemed unnecessary after the 60th interview. The results showed that low adoption of agricultural mechanization technologies is due to poor access to commercial lands, gender biases, lack of access to credit, and poor awareness about the benefits of these technologies. In conclusion, the low adoption of agricultural mechanization technologies is preventing women farmers in the Karaga District and elsewhere in Ghana from fully participating in commercial agricultural production. It is recommended that gender biases and cultural stereotypes be addressed to improve women farmers’ access to lands and credit, which will facilitate the adoption of mechanization technologies and lead to improved agricultural production.

The role of agricultural mechanization technology in the promotion of scientific and technological achievements in agriculture

Agricultural mechanization is to the use advanced and applicable agricultural machinery and equipment in agriculture to improve agricultural production conditions, and continuously improve the production technology and economic, ecological processes of agriculture. The level of agricultural science and technology depends largely on the degree of agricultural mechanization promotion. An agricultural country level depends on the degree of modern agricultural mechanization level of the application, and the era of mechanization in agriculture can not only save a lot of labor, reduce labor intensity, but also improve labor efficiency, and enhance resistance to natural disasters. The importance of agricultural mechanization technology in the scientific and technological achievements in agriculture is visible.

Analysis and Reflections on Some Problems of Agricultural Mechanization

With the development of agriculture, mechanization has shown its great advantages in its development process. From the development side, based on the experience of relevant experience of developed countries and some regions of the experiment, the mechanization of agriculture can contribute fully to the development of agriculture and other aspects of the scale. Thus, agricultural mechanization can be said that the latest form of agriculture in the 21st century. But from a practical point of view, although the mechanization of agriculture has unparalleled advantages, but also in the process of operation exposed a lot of problems.

China's Rural Industrialization and Agricultural Mechanization

Rural industrialization provides nonfarm employment opportunities and financial support for farmers and may be a non-negligible cause of agricultural mechanization in China.However,there is a lack of empirical studies on this topic due to challenges in obtaining data and identifying causal relationships.In this paper,we use multiple data sources and construct an instrumental variable based on the number of handicraft production cooperatives in 1957 to test empirically the causal effect of rural industrialization on agricultural mechanization.The results show that rural industrialization contributes significantly and robustly to agricultural mechanization.A 10 percent increase in the average number of industrial enterprises per township was associated with a 1.05 percent increase in the agricultural machinery power per unit area of arable land.Both the demand effect and income effect played crucial roles in the interaction between these two phenomena.

Spatial Spillover Effects of the Impact of Agricultural Mechanization on Carbon Emission Intensity in Agriculture:An Empirical Study Based on the Panel Data of 282 Cities

The extreme weather caused by the global warming effect has triggered huge losses to agricultural production.A hot issue for governments and scholars is how to effectively reduce carbon emission intensity in agriculture.The agricultural farming practices that are high pollution and high energy cosuming have exacerbated the vulnerability of regional agroecosystems.The sustainable development of agriculture is faced with the two dilemmas of a low utilization rate of green resources and the serious pollution of farmland.Further,environmental and ecological carrying capacities have reached theirlimits,seriouslyhinderingtthe high-quality development of low-carbon agriculture in China.Thus,based on the panel data of 282 cities,the Spatial Dubin Model(SDM)is employed to examine the impact of agricultural mechanization on carbon emission intensity in agriculture.It is found that from 1999 to 2019 carbon emission intensity in agriculture showed an overall downward trend;as of 2019,the agricultural field had completed the target of carbon emission reduction,,oneyear aheadof schedule.From a local perspective,approximately 14.89%6of fagricultural industries in prefecture-level city have still not achieved carbon emission reduction targets,and agricultural carbon emission reduction tasks were better completed in major grain-producing areas than in nonmajor grain-producing areas.Agricultural mechanization has significantly reduced carbonemission intensityyinlocal agriculture production.The impact of agricultural mechanizationoncarbon emission intensity in agriculture has not only a significant negative spatial spillover effect but also a significant effect on spatial carbon emission reduction.Compared with non-major ggrain-producingareas,agricultural mechanization plays a greater role in reducing spatial carbon emissions in major grain-producing areas.Further studies find that agricultural mechanization is conducive to overcome difficulties,such as instability of property rights and land fragmentation,and to achieve large-scale agricultural production,thereby reducing agricultural carbon emissions in nearby regions.However,the transfer of rurallabor,adjustments to the structure of agricultural cultivation,and the centralized use of rural land restrict the development of the crossregional service market for agricultural machinery,which in turn weaken its contribution to spatial carbon emission reduction.At the end of this paper,it is suggested that Chinese governments at all levels should introduce subsidy policies for the cross-regional operation of agricultural machinery to solve the problem of their service market failure.Efforts should be made to stimulate the market to develop more energy-efficient and environmentally friendly agricultural machinery products while strictly controlling changes in the use of arableland in non-grain-producing areas,which aims to serve further agricultural mechanization and boost the high-quality development of low-carbon agriculture.

The Impact of Digital Financial Inclusion on Agricultural Mechanization:Evidence from 1,869 Counties in China

In light of China's generally backward agricultural mechanization levels,it becomes crucial to shore up this weak link with endogenous driving force.The digital financial inclusion offers a approach to addressing the challenges related to agricultural mechanization.This study,collecting data from 1,869 counties and using the Spatial Autoregressive Model with Spatial Autoregressive Disturbances(SARAR model),analyzes the equilibrium and disequilibrium effects of digital financial inclusion on agricultural mechanization,as well as the mechanisms through which digital financial inclusion operates.The findings indicate that both digital financial inclusion and agricultural mechanization exhibittspatialspillovereffects.The development of digital financial inclusion emerges as a significant driver for promoting agricultural mechanization.Furthermore,the impact of digital financial inclusion on agricultural mechanization varies based on the level of agricultural economic development,with counties characterized by less developed agriculture,plain topography,and strong agricultural sectors benefiting more from digital financial inclusion.Additionally,digital financial inclusionini directlyboosts agricultural mechanizationby increasing farmers income and encouraging investment in fixed assets.Therefore,it is crucial to harness the benefits brought by the development of digital financial inclusion while promoting agricultural mechanization,and regions should tailor their approaches to promote digital financial inclusion development according to their local conditions.

Perception of the Mechanization of Rice Cultivation and Its Effects on the Soil in the Senegal River Valley

In Senegal, particularly in the Senegal River valley, agricultural mechanization remains limited, mainly due to a lack of agricultural equipment, a lack of expertise in agricultural machinery and an apprehension of the consequences on soil quality. To better understand agricultural mechanization of rice cultivation, this survey study has been carried out in the Senegal river valley. Precisely, this work aimed to characterize farm machinery and its effects on soil and rice cultivation. A questionnaire was administered to 304 out of 1270 farmers, spread over 8 rice-growing areas, 4 of which are located in the Podor department, three in Dagana and one in Saint-Louis. The results showed that 99.3% of farmers used motorized equipment, with 95.7% using tractor and 3.6% a power tiller. Offset tillage, which is a shallow cultivation practice carried out to break up hard soil without turning it over, was most widespread among growers (95.4%). 78.3% of the valley’s farmers felt that the machinery used to carry out tillage operations was inefficient. According to the farmers, the main constraints on the use of agricultural machinery in the valley were: the upkeep and maintenance of equipment (57%), the lack of expertise in mechanization (31%), and issues adapting machinery to local conditions (12%). Those constraints have contributed to a drop in yields in recent years, the spread of weeds on cultivated plots and the gradual degradation of the soil in the area according to 78% of farmers.

Farmers'Exit from Land Operation in Rural China:Does the Price of Agricultural Mechanization Services Matter?

This study uses data covering 3,914 farm households,collected from Henan province in China,to investigate the links between the price of agricultural mechanization services and farmers'exit from land operation.The results indicate that the increasing price of agricultural mechanization services leads tofarmers leaving land operation,especially when the high sunk costs and the long-term breakeven period of self-owned machinery are considered.This effect is intensified by the rapid rural-urban migration in China.Further analysis reveals that the surge in service prices reduced land renting-in and encouraged non-grain production.Our analysis suggests that the agricultural mechanization service market in China tends to work against the survival of smallholder farmers.However,the price of agricultural mechanization services is conducive to eliminating less-productive farmers and cultivating new agricultural operators.

Improved estimation model and empirical analysis of relationship between agricultural mechanization level and labor demand

The research on the relationship between mechanization level in planting industry and labor demand was carried out based on the present literatures.The former estimation model of labor demand in planting industry was established without analyzing the effects of planting structure on labor demand in planting industry.The purpose of the research is to develop and perfect the theory of estimating both labor demand and rural surplus labor in planting industry,then to provide some theoretical references for scientific estimation.The model established in this research can be used to calculate not only the amount of current labor demand,but also the demand in the various moment of future according to forecasted mechanization level and cultivated areas.Furthermore,it was explored how to obtain the indexes of cultivated areas,mechanization level and the average cultivated area that each labor can burden when the mechanization level is 0 and 100%.According to statistics principle,the methods of inspection to eliminate abnormal data and data processing were given in order to make the data more credible.Finally,an example was presented for demonstration purposes.

Overview on Soil Compaction and Sugar Beet Growth

With the advancement of agricultural mechanization,soil compaction has become a serious environmental problem.Soil compaction can increase soil bulk density and firmness,reduce porosity and permeability,and deteriorate soil structure,ultimately inhibit sugar beet growth and reduce both root yield and sugar content.However,few farmers recognize the link between soil compaction and these adverse effects.Soil compaction has a cumulative effect,with significant differences observed in the vertical range of compaction accumulation.The most significant soil compaction occurs in the topsoil of 0-10 cm,and the influence depth can reach 70 cm,but it is small in deep soil,and the inflection point is at a soil depth of 10 cm.The degree of soil compaction is related to soil type,water content,tractor shaft load,tyre type,tyre pressure and operation speed,etc.Therefore,in the production process of sugar beet,it is advisable to avoid high-humidity operations,use low pressure tyres,reduce the number of tractor-units passes over the farmland,and implement agricultural and agronomic measures to minimize soil compaction.These practices will help protect the soil environment and ensure sustainable production of sugar beets.

Controlling Agricultural Tridimensional Pollution through Circular Economy Mechanism

Agricultural tridimensional pollution （AtriP） has multi-directional and complicated chains. Circular economy is found to be an efficient mechanism that can help control AtriP. The application of three circular economic modes in agriculture and its related industries call not only interdict the AtriP chains in different stages and different directions, but also produce greater ecological, social and economical returns with less input. Nevertheless, it is a complicated systematic engineering to construct and implement effective circular economic modes to bring AtriP under control, and it depends not only on the support of the relevant technology system, but also on the supports of the relevant policies and law systems.
