Crop production for the Sierra Nevada National Park

Crop production resulted as the most relevant ecosystem services for Sierra Nevada after conducting a focus-group with local managers. Taking this into account, we quantified the amount of different crop types in Sierra Nevada based on land use and land cover maps. Then we analysed the average crop yield from official statistics for five reference years over a 10-year period for all types of crops, both on irrigated and dry land. The calculation of yields by crop, area and type of farming (dry and irrigated) was validated by conducting group interviews. Finally, we calculated the total crop production per year (kg/ha/year) in 30 m × 30 m grid cell.
