Farmers’ knowledge on fall armyworm (spodoptera frugiperda) pesticide application and its relationship with quantity of maize that is lost to fall armyworm
Views:336Fall armyworm (Spodoptera frugiperda) has spread rapidly and posed numerous threats to the food security and livelihood of millions of smallholder farmers in Ghana. This study quantifies the damages of fall armyworm infestation in maize production and identifies the various methods used in controlling fall armyworm infestation. Almost all farmers 94% experienced fall armyworm infestation on their farms. They cited key common visual damages as yellowish leaves, stunted growth, poor yield quality, holes in leaves, and egg masses on leaves. Farmer’s loss an average of GH¢2616.07 to fall armyworm infestation. Pesticide application is the frequent control measure mostly used by farmers. Farmers do not mostly use biological methods for the control of the fall armyworm. The use of pesticide as a control method is however not effective as about GH¢ 3 000 per 1 acre is lost with the use of insecticides. It is recommended that the use of other control measures like the contemporary measures involving the use of birds and chickens as predators of eggs and worms of fall armyworm should be encouraged.

Estimation of Armington elasticities: case of vegetables in Mongolia
Views:445Mongolian people often consume meat more than vegetable in diet due to traditional nomadic culture. Nowadays, the Mongolian people’s diet has been changing who consume more vegetables with associated urbanization (half of the population live in urban areas, mostly in the capital city). Even though vegetable consumption has been increased recently, the vegetable market is still a high reliance on imports and threatening national food security. Since 2016, the Mongolian government has especially paid attention to increasing vegetable's domestic production and substitution to import vegetables (Ministry of food and Agriculture, 2017). Therefore, this paper provided to substitution elasticity (the Armington elasticity) between import vegetables and domestic vegetables in Mongolia. Additionally, we estimated the home bias value of vegetables. The so-called Armington elasticities are widely used for computable general equilibrium (CGE) analysis, which determines a degree of substitution between import goods and domestically produced goods. Several of the authors studied Armington elasticities at the product level. We choose six vegetables (such as potato, garlic and onion, tomato, carrot and turnips, cabbage, and cucumber) related to lack of information. The empirical result shows that the Armington elasticities in the long-run higher than the short-run with exception of potato which means that products are similar in the long-run. However, our estimated Armington elasticities are quite lower than the previous studies result which means that Mongolian people indicated more prefer home growing vegetables than import vegetables. Moreover, we found that the home bias value is high in the short-run even long -run, this appears to be a higher relative weight on home vegetables.

The motivations for the diversification of the Nigerian economy focusing on sustainable agriculture
7-13Views:397Agriculture is one of the major branches of the economy in Nigeria, the most populous country in Africa. It employs around 70% of the population and its contribution to the national GDP ranges around 45% (2012). In spite of the fact that most of the area is arable the majority of food, the Nigerian population consumes, comes from imports. The paper attempts to provide in insight to the reasons, why Nigeria could still not achievew self sufficiency from major food crops and livestock. Beyond the rapid growth of the population, one of the major reasons is the rich oil and natural gas reserves, the exploitation and export of which has been providing with the country with “easy cash” for the recent few decades. Another reason is that the agricultural holdings are small and scattered, and farming is carried out with simple tools and techniques. Modern and large-scale farms are not common. The political leadership and economic decision makers of the country already recognized the necessity of the development of the food and agricultural sector, which – contrary to the oil industry – would exercise a deep and positive impact on the rural society as well. Nigerian agriculture is being transformed towards commercialization at small, medium and large-scale enterprise levels.

THE ROLE AND IMPACT OF DIGITAL TRANSFORMATION ON THE DEVELOPMENT OF SMALL AND MEDIUM-SIZED ENTERPRISES IN HAJDÚ-BIHAR COUNTY
Views:319In our survey-based research, assessed the opinions of 39 small and medium-sized enterprise (SME) leaders in Hajdú-Bihar County on digitalization, how they evaluate their employees' digital skills, what digital best practices they apply, and how familiar they are with current trends in digital best practices. In the literature review, we touch on the concepts and significance of digitalization and digital transformation, the characteristics and types of best practices, benchmarking as a tool for identifying them, and the steps involved in their implementation. We introduced five currently popular digital best practices: optical character recognition, homomorphic encryption, robotic process automation, intelligent process automation, and blockchain technology. The advantages and impact of these practices on corporate efficiency are highlighted. Based on the results, we reached the following conclusions:
The findings show that most Hungarian companies view digitalization as an opportunity, but there are deficiencies in strategic planning and commitment. Although leaders theoretically support technological progress, 93% of companies do not have a developed digital strategy, and leaders also rate employee engagement as low. The resources allocated for digitalization investments are also low, with most companies spending only between 0-10 million HUF. The application of artificial intelligence (AI) technologies is still in its early stages, though there are positive examples. Dissatisfaction is evident regarding employees' digital competencies, particularly in problem-solving and data security. The lack of knowledge of modern digital technologies also hinders innovation. Companies' digital maturity is low, with most having only taken initial steps in this area. Often, the perceived digital intensity of the industry does not reflect reality, which can hinder development. -
Economic questions of land usage – scarcity, sustainability
43-47Views:284The aim of this paper is to show the economic importance of land usage. This topic is important because land is the basis of industrial and agricultural production, as well as energy and environmental security.
