Sifting through the wreckage of MH17, searching for sense amid the horror

Any journalist should hesitate before saying this, but news can be bad for you. You don’t have to agree with the analyst who reckons “news is to the mind what sugar is to the body” to see that reading of horror and foreboding hour by hour, day after day, can sap the soul.

This week ended with a double dose, administered within the space of a few hours: Israel’s ground incursion into Gaza and, more shocking because entirely unexpected, the downing of Malaysia Airlines flight MH17 over Ukraine, killing all 298 on board.

So in Gaza we look at the wildly lopsided death tolls – nearly 300 Palestinians and two Israelis killed these past nine days.

The different responses these events stir in those of us who are distant, and the strategies we devise to cope with them, say much about our behaviour as consumers of news. But they also go some way to determining our reaction as citizens, as constituent members of the amorphous body we call public, or even world, opinion.

As I write, 18 of the 20 most-read articles on the Guardian website are about MH17. The entry into Gaza by Israeli forces stands at number 21. It’s not hard to fathom why the Malaysian jet strikes the louder chord. As the preacher might put it, “There but for the grace of God go I.” Stated baldly, most of us will never live in Gaza, but we know it could have been us boarding that plane in Amsterdam.

Which is why there is a morbid fascination with tales of the passenger who changed flights at the last minute, thereby cheating death, or with the crew member who made the opposite move, hastily switching to MH17 at the final moment, taking a decision that would have seemed so trivial at the time but which cost him his life. When we read about the debris – the holiday guidebooks strewn over the Ukrainian countryside, the man found next to an iPhone, the boy with his seatbelt still on – our imaginations put us on that flight. Of course we have sympathy for the victims and their families. But our fear is for ourselves.

It’s quite true that if the US truly decided that Israel’s 47-year occupation of Palestinian territory was no longer acceptable, that would bring change.

The reports from Gaza stir a different feeling. When we read the Guardian’s Peter Beaumont describe the sights he saw driving around the strip on Friday morningthree Palestinian siblings killed by an Israeli artillery shell that crashed into their bedroom, a father putting the remains of his two-year-old son into a plastic shopping bag – we are shaken by a different kind of horror. It is compassion for another human being, someone in a situation utterly different to ours. We don’t worry that this might happen to us, as we now might when we contemplate an international flight over a war zone. Our reaction is directed not inward, but outward. More

There is an interesting article by Chris Hedges entitled It's NOT going to be OK on the current economic disparity which, he believes could lead to a drastic decline in democracy as states respond to social protests. The question I ask is what can be done to slow or erradicate this process? Editor

Challenge in Sao Paulo: Overcoming Water Scarcity in South America’s Largest City

Last March, one of Brazil’s most important newspapers, O Estado de S. Paulo, published a version of the article below, which summarizes the Conservancy’s efforts to help secure Sao Paulo’s water supply. It is translated and reprinted here with permission.

By João Campari and Samuel Barrêto, The Nature Conservancy

The inhabitants of Sao Paulo have been dealing with discouraging images of cracked riverbeds where they used to see flowing water, making this temperate part of Brazil look more like the country’s semi-arid region. Unfortunately, these stark images show the worsening struggles of the Cantareira system, one of the greatest water supply systems in the world.

Right now, the Cantareira’s reservoirs — responsible for providing water for more than 12 million inhabitants of the Sao Paulo Metropolitan Region (RMSP) and Campinas — are operating at less than 15% capacity*, the lowest level recorded since the Cantareira’s creation in the early 1970s.

The images, the symbol of the current crisis, show that water doesn’t really come from the taps in our houses. It comes from nature, and in Sao Paulo much of that nature is the Atlantic Forest. While water rationing gets peoples’ attention and is one of the necessary responses to water scarcity, rationing alone is not enough to solve the long-term problem of securing lasting access to fresh water.

We must look beyond the tap and work to take care of our water supplies at their sources. We need a systemic response for the management of watersheds to restore the sources of our water that have been degraded, polluted and deforested. Forests are very important for healthy fresh water supplies. Unfortunately, the Cantareira system alone has lost 70% of its original forest cover, aggravating the sedimentation of rivers and dams, and decreasing their ability to supply water.The degradation of native vegetation also worsens the effects of erosion and drought.

The interaction of all these factors — deforestation, sedimentation, erosion and drought — leads to a situation of extreme risk and represents an environmental, social and economic threat not just to Sao Paulo, but to the entire country of Brazil. The Sao Paulo Metropolitan Region and Campinas together are responsible for more then 22% of the country’s GDP. Therefore, it is a priority to create a strong and strategic response to the increasing and urgent problems of water quantity, quality, access and supply for urban centers.

Protecting Water Supplies at their Sources

We must go beyond conventional interventions, such as engineering works — more dams or aqueducts are not the answer. Wider, systemic responses are necessary, and the responsibility to act is not limited to the government. We all need water and it is the shared responsibility of businesses, communities and civil society as a whole to search for solutions together. The government’s role is to foster and implement multiple solutions that reach multiple stakeholders at once.

The Conservancy’s work shows that one of the highest priorities for securing Sao Paulo’s water supplies is strengthening the Cantareira system’s “green infrastructure” by restoring the degraded forests of the Atlantic Forest, as well as conserving existing forest remnants. Such initiatives ensure the health of a watershed. This type of solution, when well managed, minimizes the risk of extreme events and reduces the vulnerability of populations to floods and prolonged droughts. Healthy forests also store water and reduce erosion and provide environmental services of water regulation and security to the population.

New York City illustrates this equation quite clearly. Decades ago, the city’s administration compared the costs of both natural and built infrastructure for protecting and providing water. Preserving the forests that were source of the city’s drinking water cost US $1 to 1.5 billion over 10 years. That amount was seven times lessthan the estimated US $6 to 8 billion needed to build a traditional, engineered water treatment and distribution network. (That amount doesn’t include the additional and ongoing operational and maintenance costs of $300 to $500 million a year that would have been necessary.) Obviously, nature was the better buy for the people of New York.

It is something for Sao Paulo to consider. A recent study by the Conservancy showed that restoring about 35,000 acres of deforested areas and preventing erosion on 5000 acres within the basins of the Piracicaba, Capivari, Jundiaí and Alto Tietê rivers would decrease the level of sediments that clog the rivers by 50%. Reducing erosion would increase the capacity of water reservoirs and simultaneously decrease the cost of treatment for the removal of sediments.

What the Conservancy is doing in Sao Paulo

To help accomplish restoration goals in the lands around Sao Paulo’s Cantareira system, the Conservancy-led Water Producers Project provides payments to farmers and ranchers who conserve forests on properties that are part of the watershed that feeds the Cantareira reservoirs. This payment-for-environmental-services program recognizes and compensates landowners for the water-producing value their lands provide.

The Conservancy also leads the Water for Sao Paulo Movement. This initiative fosters conversation and working relationships between different stakeholders and focuses on the importance of both water conservation and nature-based solutions for securing the water supply of the region. Because healthy forests are so important for healthy rivers and water supplies, Water for Sao Paulo seeks to restore degraded forests near the urban area.

Finally, Sao Paulo must strengthen the existing Watersheds Committees. Created by the Brazilian Legislature, Watersheds Committees discuss and make decisions about the use of water from specific river basins and are some of the most important collaborations for achieving a balance between water supply and demand.Committees include representatives of local governments, water supply companies and civil society, who are responsible for tasks such as approving water management plans, defining actions for conservation of biodiversity and mediating conflicts about the use of water resources. There are more than 200 of these groups in Brazil.

The current crisis in the Cantareira system is both a challenge and an opportunity to learn from the past and make better decisions for the future. If we have the discernment to act in a systemic way and the political and institutional capacity for change, we will be able to reduce the risks of a permanent cycle of water shortage. In addition to this, we have the opportunity to show how healthy watersheds contribute to water security, which is indispensable for Sao Paulo’s social and economic stability into the future.

*Since this article was published in March, the need for concerted action in Sao Paulo has become even more urgent. The level of water in the Cantareira system has now dropped – to about 8% of its overall capacity. As an emergency stopgap to provide water to the city, the government of Sao Paulo spent US$36 million on emergency constructions to allow access to water stored below the level of the pumps. Known to water managers as “dead volume,” this water was never intended to be part of the water supply, and the reservoirs are now, essentially, operating at a deficit. More
