說明
In the recent past, the Horn of Africa witnessed an upsurge in the desert locust (Schistocerca gregaria) invasion. This has raised major concerns over the massive food insecurity, socioeconomic impacts, and livelihood losses caused by these recurring invasions. This study determined the potential vegetation damage due to desert locusts (DLs) and predicted the suitable habitat at high risk of invasion by the DLs using current and future climate change scenarios in Kenya.

取樣方法
Freely available data on DL occurrence were acquired from the FAO DL hub (https://locust-hub-hqfao.hub.arcgis.com, accessed on 10 June 2021). The DL occurrence data that were collected between 1 February and 31 August 2020 were used.
| 研究範圍 | This study was conducted in Turkana County (Figure 1), a semi-arid region in northwestern Kenya covering approximately 68,232.9 km2 with a population of 926,976 people and an annual population growth rate of 0.81% [32]. Turkana lies between latitudes of 1°30′00″ N and 5°30′00″ N and longitudes of 34°30′00″ E and 36°40′00″ E. |

方法步驟描述:
- The normalized difference vegetation index (NDVI) for the period 2018–2020 was computed using multi-date Sentinel-2 imagery in the Google Earth Engine platform. This was performed to assess the vegetation changes that occurred between May and July of the year 2020 when northern Kenya was the hotspot of the DL upsurge. The maximum entropy (MaxEnt) algorithm was used together with 646 DL occurrence records and six bioclimatic variables to predict DL habitat suitability.
