Volume 8, Issue 4 , October 2022, , Pages 545-560

http://dx.doi.org/10.22034/GJESM.2022.04.07

Abstract
  BACKGROUND AND OBJECTIVES: This study analyzed the changes in land use and land cover trends and their implication on malaria transmission using satellite imagery applications. Deforestation or human land use activity related to water and development has expanded the ideal habitats for malaria-carrying ...  Read More

G. R. Puno; R. C. Puno; I. V. Maghuyop

Volume 7, Issue 2 , April 2021, , Pages 225-238

http://dx.doi.org/10.22034/gjesm.2021.02.06

Abstract
  BACKGROUND AND OBJECTIVES: The study involved developing a two-dimensional flood model to analyze the risk exposure of land use/land cover based on the generated flood hazard maps for the six return period scenarios in the Solana watershed.METHODS: The approach consisted of applying hydrologic and hydraulic ...  Read More

Land use and land cover spatiotemporal dynamic pattern and predicting changes using integrated CA-Markov model

A. Azizi; B. Malakmohamadi; H.R. Jafari

Volume 2, Issue 3 , September 2016, , Pages 223-234

http://dx.doi.org/10.7508/gjesm.2016.03.002

Abstract
  Analyzing the process of land use and cover changes during long periods of time and predicting the future changes is highly important and useful for the land use managers. In this study, the land use maps in the Ardabil plain in north-west part of Iran for four periods (1989, 1998, 2009 and 2013) are ...  Read More
