Statistical analysis shows the rapid increase in damaged and destroyed buildings within the zone, from 15% to 90% between October 2023 and February 2024. Satellite-derived analysis undertaken on 29 February 2024 on 4042 buildings within the zone, shows 3033 destroyed, 593 damaged (severe or moderately) and 416 with no visible damage.

UNOSAT code: CE20231007PSE This map illustrates satellite-detected changes in agricultural areas in a stretch of land 1 km from the Armistice Demarcation Line in the Gaza Strip, Occupied Palestinian Territory. UNOSAT conducted an analysis utilising Sentinel-2 satellite imagery captured between January 2018 and 2024, performing a Normalised Difference Vegetation Index (NDVI) analysis as well as a multi-temporal classification to identify notable changes in agricultural areas during that time frame. 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 permanent crop fields, arable land, and fallow lands. UNOSAT analysis and statistics presented show the damaged agricultural area in sq km, percentage and percentage change for only the area contained within the zone. Statistical analysis shows an increase on the percentage of damaged agricultural land in October 2023 from 5.36% to 33.13% of damaged land in February 2024.

UNOSAT code: CE20231007PSE This map illustrates satellite-detected changes in agricultural 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 January 2018 and 2024, performing a Normalised Difference Vegetation Index (NDVI) analysis as well as a multi-temporal classification to identify notable changes taking place in agricultural areas during that time frame. The methodology evaluated the damage as a substantial decline in the health and density of crops in January 2024, in comparison to the preceding six seasons spanning from 2018 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 permanent crop fields, arable land, and fallow lands. UNOSAT analysis shows that the agricultural extent in the Gaza Strip is estimated to be 178 sq. km, accounting for approximately 49% of the total area of Gaza, following an extensive land cover analysis. Compared to the average of the previous six years, approximately 34% of the permanent crop fields and arable land in the Gaza Strip exhibited a significant decline in health and density in January 2024. Crop analysis shows that 21% of the arable land has been damaged. Furthermore, the analysis shows that there has been a significant increase in damage to the permanent crop fields and arable land in the Deir al-Balah Governorate, with around 56% of its agricultural land being impacted. Additionally, there has been an increase in agricultural land damage in the Khan Yunis Governorate, rising from 3% to 14% between imagery collected in December 2023 and January 2024. This is a preliminary analysis and has not yet been validated in the field.

UNOSAT code: CE20231007PSE This map illustrates satellite-detected changes in agricultural 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 December 2017 and 2023, performing a Normalised Difference Vegetation Index (NDVI) analysis as well as a multi-temporal classification to identify notable changes taking place in agricultural areas during that timeframe. The methodology evaluated the damage as a substantial decline in the health and density of crops in December 2023, in comparison to the preceding six seasons spanning from 2017 to 2022. 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 takes into account the damage that affects both active crop fields, fallow lands, and a multitude of household gardens. UNOSAT analysis shows that the agricultural extent in the Gaza Strip is estimated to be 185 sq. km, accounting for approximately 50% of the total area of Gaza. Compared to the average of the previous 6 years, approximately 18% of the arable land in the Gaza Strip has exhibited a significant decline in health and density in November 2023. Furthermore, the analysis shows that there has been a significant increase in damage to the arable land in the North Gaza Governorate, with around 39% of its land being impacted. Additionally, there has been an increase in agricultural land damage in the Gaza Governorate, rising from 17% to 27% between imagery collected on November 2023 and December 2023. This is a preliminary analysis and has not yet been validated in the field.
