A brief review of nanotechnology application in detection of mycotoxins and in agriculture sector was presented. Mycotoxins are secondary metabolites produced by fungi. Their toxicity is the reason for implementation of various screening methods to detect them. During the last years, the highlight was put on nanoscale materials included in biosensors, which were some of the smart devices used f...
Agriculture is one of the most important aspects of human civilization. The usages of information and communication technologies (ICT) have significantly contributed in the area in last two decades. Internet of things (IOT) is a technology, where real life physical objects (e.g. sensor nodes) can work collaboratively to create an information based and technology driven system to maximize the be...
Improved assessment methods for agriculture production systems are needed to identify the risks and opportunities related to global changes in climate, markets and policies, and the consequences of alternative options of coping with and mitigating the changes. This paper presents the AGRISIMU modelling framework developed for ex-ante assessment of alternative policy and management options meant...
This paper shows, in a two-sector Malthusian model of endogenous population growth, that output per capita, population density, and industrialization depend upon the labor intensity of agricultural production. Because the diminishing returns to labor are less pronounced, high labor intensity (as in rice production) leads not only to a larger population density but also to lower output per capit...
This paper documents a significant impact of climate variation on urbanization in sub-Saharan Africa, primarily in arid countries. By lowering farm incomes, reduced moisture availability encourages migration to nearby cities, while wetter conditions slow it. The paper also provides evidence for ruralurban income linkages. In countries with a larger industrial base, reduced moisture shrinks the ...
The arrangements for agricultural extension in India have grown, over the last five decades, in terms of activities, organisational types and available manpower. Public sector extension, represented mainly by the State Department of Agriculture (DoA), continues to be the most important source of information for the majority of farmers. Activities of other extension agencies, be it Non-Governmen...
This paper is intended to make a contribution to the empirical literature explaining the rise of unemployment since the 1970s in western economies by means of interactions between shocks and institutions. The contribution is twofold. First, the impact of a general feature of developed economies that has been surprisingly neglected in the literature is analyzed, namely, the employment shift from...
on one hand, Iran due to the low annual rainfall and lack of appropriate spatial and temporal distribution in precipitation is considered as an arid and semi-arid country experiencing stress and water scarcity; on the other hand, 90% of annual water consumption has been allocated to agriculture sector in Iran and efficiency and productivity of water consumption do not enjoy favorable status in ...
