IndicatorsPressure parametersStateResponse
Hydrology Variation in per capita water availability in the last 5 years Per capita water availability Improvements in water use efficiency over the period 
BOD5 over the past 5 years Average BOD5 (long term) Improvements in sewage treatment over the period 
Environment EPI of the watershed Percentage of the watershed with natural vegetation Evolution in terms of watershed conservation (reserves, good management practices) 
Life Variation of the HDI of the watershed region over the past five years HDI weighted by municipal area Evolution in the HDI of the watershed region in the period 
Policy Variation in HDI in education (HDI-education) Legal and institutional capacity in terms of integrated watershed management Evolution of IWRM spending in the period
