The paper investigates the activities of a small group of Italian wine producers and farmers within the agricultural landscape around Piacenza, and the way they influence the transformation of local urban and rural environments through either the application of the principles promoted by the Slow Food organization, or the creation of alternative “unofficial” strategies. Through the analysis of documents relating to the past and present history of the agricultural territory around Piacenza and its material culture, the presented study aims to understand how historically consolidated contexts are physically transformed through food culture. Considering historical and economic works on the Italian agricultural landscape, the paper stresses the dichotomy between consolidated cultural practices acting on a historically traditional landscape, and the innovation coming from the subversion of those practices, by visualizing them through a qualitative-quantitative gastronomic map of the local territory.展开更多

Concentration of agricultural share of agricultural land in total surface. economic development, compared to the land is observed on areas with fertile soils This is the effect of the socio-economic countries of Western Europe, and rural and in the less industrialized central and eastern parts of the country. The lowest shares of agricultural land are observed on areas featuring natural conditions disadvantageous for farming, the highly forested North-Western Poland, and the areas characterized by high degree of industrialization and urbanization. The contemporary ownership structure in Poland is the effect of historical transformations of the social, economic and political relations. The pattern of the ownership structure developed over the centuries, and it is the resultant of the diverse socio-economic processes.展开更多

We collected data on global changes(landscape and climate) and economic damage caused by six main insect pests during 1951–2010 in China. Landscape changes had significant effects on all six insect pests. Pest damage increased significantly with increasing arable land area in agricultural landscapes. However, climate changes had no effect on damage caused by pests, except for the rice leaf roller(Cnaphalocrocis medinalis Guenee) and armyworm(Mythimna separate(Walker)), which caused less damage to crops with increasing mean temperature. Our results indicate that there is slight evidence of possible offset effects of climate changes on the increasing damage from these two agricultural pests. Landscape changes have caused serious outbreaks of several species, which suggests the possibility of the use of landscape design for the control of pest populations through habitat rearrangement. Landscape manipulation may be used as a green method to achieve sustainable pest management with minimal use of insecticides and herbicides.展开更多
