The aim of the study is to assess the factors that influence the sustainability of agricultural development. The study was carried out in the municipality of Bobonaro for about four months, from July to October 2021. Slovin’s method was used to determine the sample size, with a desired percentage of 10% of the total population. Thus, 154 producers were interviewed as respondents and key persons in the area of agriculture. The variables interviewed are the main factors of agricultural productivity and the factors that affect sustainable agricultural development. The results of the descriptive statistical analysis of the data showed that about 94.87% of the respondents’ productive area is in operation, with an average of 1.84 ha per respondent and the abandoned area around 0.11 ha per respondent. The average value of rice production is 2.38 ton per ha and corn 1.07 ton per ha. About 87% of producers raised the main types of animals such as cattle, pigs, goats with an average density of 2 to 5 animals per establishment. About 61% of producers have access to the market at a normal price for agricultural products. The factors that hinder less successful agricultural development, such as: those of nature with the greatest impact are climate changes, which influence changes in cultivation sessions and in the characteristics of productive soils, availability of water for irrigation and animal feed. On the socioeconomic side, it includes the willingness or interest of young people who want to work as farmers, less investment and the impact of the Covid-19 pandemic. It is concluded that natural and socioeconomic impacts can reduce agricultural productivity, so that this will be a major challenge for the development of the agricultural sector in the future. 展开更多

A theory of reverse triple I method with sustention degree is presented by using the implication operator R0 in every step of the fuzzy reasoning. Its computation formulas of supremum for fuzzy modus ponens and infimum for fuzzy modus tollens are given respectively. Moreover, through the generalization of this problem, the corresponding formulas of α-reverse triple I method with sustention degree are also obtained. In addition, the theory of reverse triple I method with restriction degree is proposed as well by using the operator R0, and the computation formulas of infimum for fuzzy modus ponens and supremum for fuzzy modus tollens are shown. 展开更多

Rural geotourism looks at the natural resources of the territory as a means of promoting a specialized,educational,sustainable tourism.This is an increasingly sought-after activity.This paper presents a rural georoute across a high mountain village,highlighting the remarkable value of the geological heritage of biological trace fossils and physical sedimentary structures exposed on street pavements and façades of houses.A series of tourist georesources were created and implemented:educational and interpretive panels,videos,QR codes,geoapps and games,all of which promote and disseminate the exceptional geological content and the history of the earth through the use of new technologies(smartphones,ipod,etc.).All this is intended as a means to make geotourism a natural tourism,favoring experiences,whilst explaining the natural environment and its temporal and spatial dimensions,offering opportunities for socio-economic development and job creation in rural areas with problems of depopulation. 展开更多
