    As primeiras décadas do século XXI têm sido marcadas por uma corrida global por terras, desencadeada pelas crises agroalimentar, energética, climática e econômico-financeira. O objetivo deste artigo é analisar se os Estados Unidos estiveram na rota dessa corrida. Para tanto, examinamos dados do Departamento de Agricultura dos Estados Unidos (United States Department of Agriculture – USDA) e bibliografia especializada, e identificamos que a porção de terras em mãos estrangeiras dobrou entre 2004 e 2014.

    Soil microorganisms play an important role in agricultural ecosystems, but their response to organic fertilizer application has not been thoroughly elucidated. Thus, high-throughput sequencing was used to investigate the responses of soil bacterial to organic fertilizer amendment (composted from pig manure) in the field during the entire growth cycle of maize plants.

    Exurban development is the fastest growing land use across the United States (US). Its prevalence on the East Coast is susceptible to natural disaster events such as hurricanes and nor’easters. However, the socio-ecological processes related to disaster mitigation within exurban areas remain understudied. Our objective was to integrate social and landscape data to compare resident attitudes towards utility roadside vegetation management across four areas in the state of Connecticut, US. We collected data from residents using two mail surveys completed in 2017 and 2019 (n = 1962).

    Landscapes have multiple functions relating to natural preservation and cultural inheritance, which are fundamental factors for tourist development. Particularly in villages, rural tourism is primarily based on the rural landscape. However, peri-urban villages face complex conflicts of urbanization and ruralism, in which landscapes are dynamic and need synergistic plans and management. Thus, this research contributes to a better understanding of comprehensive landscape planning integrating natural and cultural dimensions in peri-urban villages.

    Most cases of multifunctional peri-urban agriculture offer diverse economic and ecological benefits, while a few involve cultural dimensions. In China, a “cultural turn” in the construction plan of beautiful villages has occurred. Through the analysis of policy and focus-group interviews, this research analyzes a case study of rural planning in the Pu’an village, a peri-urban village near Changzhou city in the Yangtze River Delta, China. Particular attention is given to investigating the process of identifying the local cultural symbol of a multifunctional plant, the bulrush.

    Agricultural development is facing two problems: insufficient grain production and low profit of farmers. There is a contradiction between the government’s goal of increasing production and the farmer’s goal of increasing profit. Exploring the appropriate management scale of farmland under different objectives is of great significance to alleviate the conflict of interests between the government and farmers.

    As house mortgage appraisal values have played a leading role in the 2007–2012 financial crisis, it is important to develop robust mass appraisal models that correctly estimate these values. The present paper intends to propose a methodology to examine the spatial distribution of house mortgage appraisal values. To do so, we analyzed the effect that these values, cadastral urban land values, characteristics of houses, and socioeconomic conditions and services in neighborhoods, have on house mortgage appraisal values in the 70 boroughs of Valencia (Spain).
