I believe that urges to be reinforced the connection between healthy ecossytems and water supply to urban cities. In this sense, this topic also matches with the Urban discussion group. Water provision in quantity and quality to billions of people that are increasingly dwelling cities is the major challenge to be adressed. Such challenge is strictly related to the water crisis that recently affected the great São Paulo (and it seems that it was already forgotten) and now reached Brasilia. Increasing people demanding water requires that more long-term investments must be applied to protect and restore the water source regions, which surround our big cities. Specifically, at the ecossystem level, the sollution must always be based in the increase of vegetation cover, better farming practices, waste water treatment in rural and industrial zones, rigid control of water withdrawal (e.g. irrigation), and incentives for those who provide water ecossystem services suppported by an effective policy of PES schemes.

I agree with you that, unfortunately, in the majority the population cares only with the water they see at the tap. It seems a very difficult answer to find out how to mobilize politicians and decision-makers to think and act beyond their short mandates. However, I believe we have a chance wheter we can prove and showcase that in terms of governance it is much more cost-effective to secure water by investing in healthy ecossystems. In addition, we have to make pressure for the private sector to become confident to financially support and also invest along with the public funding. It's a hard task, no doubt, mainly due to obscure political interests we know.

I'm a great fan of this: http://bbaguabrasil.com.br/, specially because it demonstrated good and low cost alternatives to secure water for small/family farmers and incentivized cases of water producers who supply clean water to big urban centres.
Governments and the private sector must pay attention to the urgent need of managing the demand and supply for water, strenghthening the link between water and cities. We can no longer anymore wait until the onset of water crisis, such that Brasilia is facing now and the other that hit Sao Paulo about two/three years ago. From the demand side good examples are the individual collection and payment of water with the use of hydrometers in each house/apartment; bonus and incentives to consumers who are saving water; fines and taxes to consumers who are wasting water or making bad use. From the supply side can be highlighted the investments on green infrasctructures to restore and protect water sources ecossystems; smart engineering solutions for withdrawal, treatment and distribution that are less harmful to the environment and most importantly, the replacement of antiquated and inefficient water distribution systems that leak to much treated water along the networks. The lack of urban (and rural) sanitation to a large extent is also a bottleneck that must be addressed, otherwise it will be ineffective investing in the management of water demand and supply in urban zones.

I hope the current crisis Brasilia is facing today could be less painful than that one São Paulo and surroundings lived a couple of years ago. However, I think a big concern is that governments fully believe in rainfall patterns as sufficient to people and the economy needs and at the same time they jeopardize the fact that severe and atypical droughts will be a trend due to changing climate.
I suggest that moderators should take the message to the WWF8 that the impact of climate change on water and cities must be more seriously adressed and transformed into practical mitigation and adaptation measures, as the ones I have mentioned in my previous comment.

I think that less developed countries are less privileged in terms of receiving appropriatted technologies from developed countries, they also lack of human resources and capacity building and sometimes they are hardly affected by corruption (e.g.: misapropriation of public funds). Interventions should firstly be focused on the maintenance and restoration of already existing water sources and catchments, instead of insiting on withdrawing water from increasingly distant sites and spending much more money with very expensive engineering works. Secondly, but not less important, we should plan our investments strongly in education and regulation/surveillance of the use of water in cities (including sanitation), enforcing water legislation as well.

Sem dúvida Angelo,
Até o presente momento, qualquer previsão climática futura por maior que seja o grau de incerteza, aponta para mudanças nos regimes de chuvas. Isso vulnerabiliza e requer muita cautela e planejamento na construção de qualquer reservatório, independente do tamanho ou local.
Acredito, portanto, que nas discussões de mais alto nível no WWF8 a ideia de segurança hídrica deve ser vista na sua forma mais ampla o possível e jamais refletida apenas em engenharia para grandes reservatórios. Como você mesmo disse, cobertura florestal é o melhor reservatório que se pode ter para a disponibilidade contínua de água.
