Abstract

Greenhouse gas emissions that are causing global warming and changing the climate of the planet have already influenced the total environment and its unique ecosystems worldwide. Declining precipitation, increasing temperature and evapotranspiration are a direct reflection of climate change. Whereas declining surface-water bodies, drought, and decreasing vegetation canopies are consequences of environmental degradation in many countries around the world. A case study from Iraq’s environmental alteration, as an extreme example of nature and human interactions, shows the degradation of surface water volumes and the total greenness canopies. However, most of the existing literature has focused on the human impact only, particularly socioeconomic development and wars, as the main cause of the environmental fall of Iraq’s ecosystems. Thus, it is a call to establish a balanced understanding of local and regional influences of global warming within such ecosystems at the landscape scale under governmental policies performances. Methods used in this study, include remotely sensed imagery, metrological datasets and related analytic tools and indexes. Analytic indexes including NDVI, SVI, PDSI, SPI and SPEI have been utilized to investigate the existing situation. The results indicated that the country is facing extreme drought and general environmental degradation except for some temporary periods (2003-2007 and 2020). According to the SVI time series, drought was obvious and most of the SVI values were below 0 which indicates dry periods. The NDVI analysis showed a clear increase in overall drought within the study site. Environmental degradation is a symptom of global warming, and population growth has put a strain on natural resources and the environment worldwide. Remote sensing analytic tools have the potential to represent human development and achievable environmental sustainability goals to prevent more harm to the environment.
