Explaining the role of green space in coastal cities in attracting tourists with the approach of sustainable environmental development (Case study of Noor city) [PDF]

تحقیقات کاربردی علوم جغرافیایی, 2023
Irregular and unstable urban development has increased marginalization, destruction of urban green areas and increased demand for urban land, which in itself has led to the disappearance of urban green spaces and land use change of such lands and is ...

Does Urban Green Space Pattern Affect Green Space Noise Reduction?

The effect of urban green spaces on traffic noise reduction has been extensively studied at the level of single vegetation, hedges, etc., but there is a lack of corresponding studies at the scale of spatial patterns of urban green spaces. Therefore, this

Urban small sites – landscape ecology and contribution to urban greenspace [PDF]

, 2009
Urban areas are highly modified and complex landscapes, within which green spaces are seen as valuable for human well being as well as wildlife. Most studies evaluate the significance of the upper end of this spatial scale (>10ha), and ignore the smaller

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Chinese Trade Competition and Rural Mexican Migration

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT China's accession to the World Trade Organization in 2001 reshaped global trade, reducing U.S. demand for Mexican manufactured goods and weakening Mexico's manufacturing employment. This study estimates how this trade‐induced decline affected migration and employment decisions among rural Mexicans.
