different regions of a country generally have different levels of agricultural development. in fact, there is a kind of heterogeneity that makes the investigation of the agricultural development trends in provinces of the country undeniable. the present article aims to analyze the level of agricultural development and its imbalance in rural regions of west azerbaijan for urban levels in 2000s. ...

This paper studies the spatial implications of structural change. The secular decline in spending on agricultural goods hurts workers in rural locations and increases the return to moving towards nonagricultural labor markets. We combine detailed spatial data for the U.S. between 1880 and 2000 with a novel quantitative theory to understand this process and to quantify its macroeconomic implicat...

Coastal aquatic ecosystems are increasingly affected by diffuse source nutrient water pollution from agricultural activities in coastal catchments, even though these ecosystems are important from a social, environmental and economic perspective. To warrant sustainable economic development of coastal regions, we need to balance marginal costs from coastal catchment water pollution abatement and ...

The evaluation system of China’s high-quality agricultural development is constructed from four aspects: efficiency improvement, innovation-driven, green development, and coordinated sharing, which level measured based on the entropy weight method (EWM), Besides, using Theil index decomposition, spatial clustering convergence theory, this paper analyzes temporal-spatial evolution characteristic...

Florida has experienced more population growth over the past half century than any other state, which has led to some of the most extensive urban development on valuable agricultural lands. To address this and other impacts of sprawl, Florida passed the Growth Management Act (GMA) in 1985, which among other things required local comprehensive planning and that it be consistent with a state plan...
