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.

agricultural machinery represents modern method and modern condition of production, and agricultural mechanization is the key basis and symbol of modern agriculture. Based on analyses of agricultural mechanization development in Guangdong Province from 1988 to 2008, production function was developed to estimate the effects of agricultural mechanization on agricultural production. The results indicated that the contribution of agricultural mechanization to production continues to increase. The agricultural mechanization increased by 1%, and grain production by0.35%. Therefore, government should encourage development of agricultural mechanization in order to improve agricultural production in Guangdong Province.

本文利用中国2007年开始实施的农业机械化示范区政策作为准自然实验，使用农村固定观察点这一具有全国代表性的数据对农业机械化与经济结构转型的因果关系进行了检验。研究发现农业机械化水平的提高促使家庭经营主业从农业转向非农业，尤其是制造业和服务业。其中，推动这种转变的主要群体是18～30岁的年轻群体以及受教育程度较高的群体。机制分析表明，农业机械化使得农户投入农业生产的时间得以节约，农业劳动生产率提升，农业收入增加，从而放宽了农户的时间和金融约束，进而提升了其向其他行业配置劳动力的概率。最后，福利分析表明这项政策的实施改善了农户的家庭收支状况，且未造成不平等和返贫现象。

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.
