Sistema de irrigação móvel por gotejamento: revisão sistemática com análise da produção científica através de indicadores bibliométricos e cientométricos

Abstract

One in nine people in the world do not have access to enough quality food to maintain a nutritional range corresponding to a healthy life. In Latin America, Brazil is an important global food producer with great potential to expand supply. Brazil has a potential of approximately 14% of the global capacities for incorporating new unproductive areas for irrigated agriculture. Agriculture is one of the activities that most demand the use of water for growing food and maintaining crops in different regions of the world, as well as the need to manage and improve water efficiency is in evidence worldwide. Science is continually looking to mitigate water loss in irrigation, and the mobile drip irrigation system (MDI) has particularities that can help reduce some parameters, such as reducing water runoff. In this sense, the objective of this study was to understand the current state of scientific production on the MDI System, through a systematic review with analysis of scientometric and bibliometric indicators. The distribution of study sites suggests a local interest from the United States and Brazil. The most frequent terms analyzed in the word cloud from the titles of the articles focus on words related to irrigation and the most frequent terms in the cloud referring to the words used in the abstracts show an emphasis on irrigation systems, management and efficiency in use from water. When analyzing the networks by co-occurrence of words, it was observed that the synergy occurs around the term drip irrigation, with terms that demonstrate a trend in soil moisture and soil water, water management. The US is the country where the largest number of MDI-related articles are located. Finally, the potential collaborations of the factorial analysis verified two clusters focused on issues of irrigation systems and the management and management of water use, thus it is concluded that the authors are aiming at a new technology, in which irrigation is interconnected with the water usemanagement.
