To understand land use change within the provided Area of Interest (AOI) between 2015 and 2020, I can retrieve the Global Land Cover and Land Use (GLCLU) data for both years.

The spatial task is to quantify the land cover distribution within the attached AOI for 2015 and 2020. I will then present these distributions, noting that direct, pixel-by-pixel change detection between these specific years would require further GIS analysis beyond a single tool call, as the glclu_layer='change' option provides transitions between 2000 and 2020, not 2015 and 2020.

First, I will get the GLCLU data for 2015: Now, I will get the GLCLU data for 2020: I have retrieved Global Land Cover and Land Use (GLCLU) data for the attached AOI, which includes parts of Kenya, for both 2015 and 2020.

Land Cover Distribution for 2015 within the AOI:

• Bare Ground: 78.91%
• Water: 2.17%
• Wetland Tree Cover: 0.50%
• Wetland Vegetation: 0.40%
• Built-up: 2.14%
• Cropland: 8.42%
• Tree Cover: 7.47%
• Ocean: 0.001%
• Snow/Ice: 0%

Land Cover Distribution for 2020 within the AOI:

• Bare Ground: 78.21%
• Water: 2.26%
• Wetland Tree Cover: 0.46%
• Wetland Vegetation: 0.36%
• Built-up: 2.56%
• Cropland: 8.83%
• Tree Cover: 7.32%
• Ocean: 0.001%
• Snow/Ice: 0%

Summary of Changes (2015 to 2020) within the AOI:

• Bare Ground decreased by approximately 0.7%.
• Water increased by approximately 0.09%.
• Wetland Tree Cover decreased by approximately 0.04%.
• Wetland Vegetation decreased by approximately 0.04%.
• Built-up increased by approximately 0.42%.
• Cropland increased by approximately 0.41%.
• Tree Cover decreased by approximately 0.15%.

This analysis provides a high-level overview of land cover changes within the provided AOI between 2015 and 2020. Please note that this AOI is larger than just Kenya. To get a precise, pixel-level land use change map specifically for Kenya between 2015 and 2020, you would need to provide an AOI specifically for Kenya, and then a dedicated GIS analysis would be required to compare the two GLCLU layers and identify transitions. The GLCLU 'change' layer available through the API currently focuses on transitions between 2000 and 2020.

The total area of the attached Area of Interest is approximately 57,823,750.19 hectares.

Based on this total area and the percentage changes between 2015 and 2020, the estimated land cover changes in hectares are:

• Bare Ground: decreased by approximately 404,766.25 hectares
• Water: increased by approximately 52,041.38 hectares
• Wetland Tree Cover: decreased by approximately 23,129.50 hectares
• Wetland Vegetation: decreased by approximately 23,129.50 hectares
• Built-up: increased by approximately 242,859.75 hectares
• Cropland: increased by approximately 237,077.38 hectares
• Tree Cover: decreased by approximately 86,735.63 hectares

The total area of the attached Area of Interest is approximately 57,823,750.19 hectares.

Here's the breakdown of land cover classes in 2020 within the AOI, in hectares:

• Bare Ground: approximately 45,221,496.06 hectares
• Water: approximately 1,306,815.25 hectares
• Wetland Tree Cover: approximately 265,990.25 hectares
• Wetland Vegetation: approximately 208,165.50 hectares
• Built-up: approximately 1,480,288.00 hectares
• Cropland: approximately 5,105,655.00 hectares
• Tree Cover: approximately 4,232,599.50 hectares
• Ocean: approximately 578.24 hectares
• Snow/Ice: 0 hectares

I have already provided the Global Land Cover and Land Use (GLCLU) values for 2020 in hectares and percentages for the attached AOI. Here they are again for your convenience:
