UNOSAT code: CE20230415SDN This map illustrates damage to structures in the city of El Fasher, North Darfur, Republic of Sudan. The damage was investigated due to a significant occurrence of fire detections from May 9-20 2024. Fire detections are sourced from multiple US Government scientific satellites utilizing the MODIS and VIIRS sensors. While some fire detections may be non-violent in nature the large majority are firmly within areas of residential structures that show indications of burning in satellite imagery. Damaged areas are visible in satellite imagery from 11 November 2023 - 31 July 2024 and are heavily concentrated in the Eastern half of the city. In total, more than 23,600 structures are estimated to have been damaged or destroyed in these areas. Out of these 23,600 structures, approximately 2,000 were found damaged before 9 May 2024; 9,500 between 9 May and 23 May 2024; over 4,600 between 23 May and 1 June 2024; 3,900 between 1 June and 12 June 2024; 600 between 12 June 2024 and 26 June 2024; and 2,900 between 26 June 2024 and 31 July 2024.

UNOSAT code: CE20231007PSE This map illustrates satellite-detected changes in cropland areas of the Gaza Strip resulting from the decline in the health and density of crops due to the ongoing conflict. UNOSAT conducted an analysis utilising satellite imagery collected by the Sentinel-2 satellite between July 2017 and 2024, performing a Normalized Difference Vegetation Index (NDVI) analysis as well as a multitemporal classification to identify notable changes taking place in agricultural areas during that timeframe. The methodology evaluated the damage as a decline in the health and density of crops in July 2024, in comparison to the preceding seven seasons spanning from 2017 to 2024. The decline in the health and density of the crops can be observed due to the impact of activities such as razing, heavy vehicle activity, bombing, shelling, and other conflict-related dynamics. The analysis includes damage assessment for orchards and other trees, field crops and vegetables. UNOSAT analysis shows that the agricultural extent in the Gaza Strip is estimated to be 150 sq. km, accounting for approximately 41% of the total area of the Gaza Strip, following an extensive land-cover analysis. Compared to the average of the previous seven years, approximately 65% of the permanent crop fields in the Gaza Strip exhibited a significant decline in health and density in July 2024. In a comprehensive evaluation, it was found that there has been a 4% increase in the proportion of cropland that has been damaged since the previous analysis conducted in June 2024. Additionally, the analysis indicates a notable rise in the destruction of the orchards and other trees, field crops and vegetables in the Gaza Governorate, with a 4-percentage point increase compared to the previous June 2024 analysis. Moreover, there has been a notable escalation in the destruction of cropland within the Rafah Governorate, with the percentage rising from 52% in June 2024 to 55% in July 2024. This is a preliminary analysis and has not yet been validated in the field.

UNOSAT code: CE20231007PSE This map illustrates a satellite imagery-based comprehensive assessment of damage and destruction to structures within the area of interest in the Gaza Strip, Occupied Palestinian Territory, based on images collected on 6 July 2024 when compared to images collected on 1 May 2023, 10 May 2023, 18 September 2023, 15 October 2023, 7 November 2023, 26 November 2023, 6-7 January 2024, 29 February 2024, 31 March - 1 April 2024, and 3 May 2024. According to satellite imagery analysis, UNOSAT identified 46,223 destroyed structures, 18,478 severely damaged structures, 55,954 moderately damaged structures, and 35,754 possibly damaged structures for a total of 156,409 structures. These correspond to around 63% of the total structures in the Gaza Strip and a total of 215,137 estimated damaged housing units. The governorates of North Gaza and Rafah have experienced the highest rise in damage compared to the 3 May 2024 analysis, with around 2,300 new structures damaged in North Gaza and around 15,030 in Rafah. Within Rafah, Rafah City municipality had the highest number of newly damaged structures, totalling almost 10,100. This is a preliminary analysis and has not yet been validated in the field.

UNOSAT code: CE20231007PSE This map illustrates satellite-detected changes in cropland areas of the Gaza Strip resulting from the decline in the health and density of crops due to the ongoing conflict. UNOSAT conducted an analysis utilising satellite imagery collected by the Sentinel-2 satellite between June 2017 and 2024, performing a Normalized Difference Vegetation Index (NDVI) analysis as well as a multitemporal classification to identify notable changes taking place in cropland areas during that timeframe. The methodology evaluated the damage as a substantial decline in the health and density of crops in June 2024, in comparison to the preceding seven seasons spanning from 2017 to 2024. The decline in the health and density of the crops can be observed due to the impact of activities such as razing, heavy vehicle activity, bombing, shelling, and other conflict-related dynamics. The analysis includes damage assessment for orchards and other trees, field crops and vegetables. UNOSAT analysis shows that the cropland extent in the Gaza Strip is estimated to be 150 sq. km, accounting for approximately 41% of the total area of the Gaza Strip, following an extensive land-cover analysis. Compared to the average of the previous seven years, approximately 63% of the permanent crop fields in the Gaza Strip exhibited a significant decline in health and density in June 2024. In a comprehensive evaluation, it was found that there has been a 9% increase in the proportion of cropland that has been damaged since the previous analysis conducted in May 2024. Additionally, the analysis indicates a notable rise in the destruction of the orchards and other trees, field crops and vegetables in the Deir Al-Balah Governorate, with a 7-percentage point increase compared to the previous May 2024 analysis. Moreover, there has been a significant escalation in the destruction of cropland within the Gaza Governorate, with the percentage rising from 61% in May 2024 to 69% in June 2024. This is a preliminary analysis and has not yet been validated in the field.
