It follows the same structure as the Global Water and Climate Programmes developed in other regions. However, it will not consider Work package 1 on cooperation at transboundary level since it is a national initiative. The lessons learned of this experience will be shared in other parts of Peru and South American countries. The Santa Eulalia sub-basin represents a key territory for the sustainability of Metropolitan Lima in terms of supplying 50% of the water and 70% hydroelectrical power consummed by the 10 million inhabitants of Lima city. The upper Santa Eulalia basin also shows very high levels of poverty and inequality. Its population endures water insecurity, food insecurity and energy insecurity, all exacerbated by increased vulnerability to the effects of climate change. We estimate that the immediate beneficiaries will be around 17,000 people, of whom almost 7,000 live in poverty. Amongst the indirect beneficiaries we consider Lima´s population and economic activities.
In addtion to what I have just mentioned, climate change is seriously affecting the retreat of the glaciers of Santa Eulalia sub basin, as shown in the image.
Nowadays, some parts of the middle and lower sub basin endures estationary water scarcity Every year local farmers celebrate the water festival, where they organise community work for cleanning irrigation channels and sing to call for rain. They depend on it to survive.
For the purpose of this presentation I will only focus on the fifth output
At the inception phase we followed a consultation process to know the needs, opportunities and perceptions of local people and authorities to determined the demostratives projects, the ecosystem services and their water related problems. We did 8 local workshops where we had the participation of women, men, youth and elderly people.
Amongst the most important ecosystem services, this sub basin provides food, energy, freshwater, natural medicines and genetic resources (the upper sub basin has a queñual forest which is an endangered species)
Other important ecosystem services provided by the sub-basin, mainly due to the conservation of forests, are erosion control, climate regulation, and flood mitigation downstream. In addition to natural ecosystems, in Santa Eulalia we also have man-made infrastructure such as terraces built during pre-inca times, which help controlling erosion and enhance ecosystem services.

Lima city benefits from those ecosystem services provided by Santa Eulalia sub basin, including food, freshwater and energy supply. In addition, the watershed provides turistic options. The climate change and poverty is severly affecting the conservation of those ecosystem services. However, these ecosystem services are taken for granted by the energy and water supply agencies and other beneficiaries, who do not consider that they should pay for these services.
Suppot the implementation of techniques aimed at conserving ecosystem services, such as restauration of pre-inca terraces, improved irrigation techniques, reforestation, amongst others. GWP has approached SEDAPAL, EDEGEL, the National Water Authority, the Ministry of Environment, academic organisations and other key stakeholders, with the purpose of bringing them together in order to join efforts towards the payment for ecosystem services. Define and valuate ecosystem services provided by the sub basin and propose payment mechanisms. The results of this process will feed into the bill for payment for ecosystems services submitted by the Ministry of Environment.
