To further understand drought, this study presented spatial and temporal variations of drought based on satellite derived Vegetation Condition Index (VCI) on annual (Jan\u2013Dec), seasonal monsoon (Jun\u2013Nov) and pre-monsoon (Mar\u2013May) scales from 1982\u20132015 in Nepal. The Vegetation Condition Index (VCI) obtained from NOAA, AVHRR (National Oceanic and Atmospheric Administration, Advanced Very High Resolution Radiometer) and climate data from meteorological stations were used. VCI was used to grade the drought, and the Mann\u2013Kendall test and linear trend analysis were conducted to examine drought trends and the Pearson correlation between VCI and climatic factors (i.e., temperature and precipitation) was also acquired. The results identified that severe drought was identified in 1982, 1984, 1985 and 2000 on all time scales. However, VCI has increased at the rate of 1.14 yr\u22121 (p = 0.04), 1.31 yr\u22121 (p = 0.03) and 0.77 yr\u22121 (p = 0.77) on the annual, seasonal monsoon and pre-monsoon scales, respectively. These increased VCIs indicated decreases in drought. However, spatially, increased trends of drought were also found in some regions in Nepal. For instance, northern areas mainly in the Trans-Himalayan regions identified severe drought. The foothills and the lowlands of Terai (southern Nepal) experienced normal VCI, i.e., no drought. Similarly, the Anomaly Vegetation Condition Index (AVCI) was mostly negative before 2000 which indicated deficient soil moisture. The exceedance probability analysis results on the annual time scale showed that there was a 20% chance of occurring severe drought (VCI \u2264 35%) and a 35% chance of occurring normal drought (35% \u2264 VCI \u2264 50%) in Nepal. Drought was also linked with climates in which temperature on the annual and seasonal monsoon scales was significant and positively correlated with VCI. Drought occurrence and trends in Nepal need to be further studied for comprehensive information and understanding.<\/jats:p>","DOI":"10.3390\/s19020430","type":"journal-article","created":{"date-parts":[[2019,1,22]],"date-time":"2019-01-22T03:08:22Z","timestamp":1548126502000},"page":"430","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":59,"title":["Spatial and Temporal Variation of Drought Based on Satellite Derived Vegetation Condition Index in Nepal from 1982\u20132015"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2827-0152","authenticated-orcid":false,"given":"Binod","family":"Baniya","sequence":"first","affiliation":[{"name":"Key Laboratory of Water Cycle and Related Land Surface Processes, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"},{"name":"Department of Environmental Science, Patan Multiple Campus, Tribhuvan University, Kathmandu 44613, Nepal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0886-6699","authenticated-orcid":false,"given":"Qiuhong","family":"Tang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Water Cycle and Related Land Surface Processes, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0058-5040","authenticated-orcid":false,"given":"Ximeng","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Water Cycle and Related Land Surface Processes, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}]},{"given":"Gebremedhin Gebremeskel","family":"Haile","sequence":"additional","affiliation":[{"name":"Key Laboratory of Water Cycle and Related Land Surface Processes, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"}]},{"given":"Gyan","family":"Chhipi-Shrestha","sequence":"additional","affiliation":[{"name":"\u00c9cole Sup\u00e9rieure d\u2019Amenagement du Territoire, Universit\u00e9 Laval, 1628 Pavillon Savard, Universit\u00e9 Laval, Qu\u00e9bec City, QC G1K7P4, Canada"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,21]]},"reference":[{"key":"ref_1","first-page":"3","article-title":"Drought as a natural hazard\u2014Concepts and definitions","volume":"Volume I","author":"Wilhite","year":"2000","journal-title":"Drought: A Global Assessment"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"204","DOI":"10.1016\/j.jhydrol.2010.07.012","article-title":"A review of drought concepts","volume":"391","author":"Mishra","year":"2010","journal-title":"J.
