Farmers in Hanoi make vegetables 'fresh' by using sewage

Sewage contains tons of viruses, bacteria, and heavy metals. In developed countries, sewage has to be carefully treated before they can be used again.
In Vietnam, farmers living around Hanoi provide thousands of tons of vegetables for the capital city everyday. Nobody has ever asked how the farmers make their vegetables look 'fresh'.
Everyday, people in Hanoi are still buying this type of vegetables because they are much cheaper than vegetables in supermarkets. Many other, because of their habits, prefer eating the vegetables raw, without knowing that sewage are used to wash the vegetables.
This video is in Vietnamese but it shows the story. Don't panic!

Meta analysis of time-series and panel studies of Particular Matter and Ozone

This is a report for WHO, conducted by experts in London. Its main task is to judge the impact of air quality on human health in European region.

Important concepts are addressed in this report:

- Time-series studies

- Meta analysis

- Publication bias

- Many interesting (a bit complicated) tables and statistics

It's worth reading this 80 -page length report.

Water and Human Security

A short, but interesting text. One of the question it asks is how water relates to international conflict?

 

As human populations and economies grow exponentially, the amount of freshwater in the world remains roughly the same as it has been throughout history. While the total quantity of water in the world is immense, the vast majority is either saltwater (97.5 percent) or locked up in ice caps (1.75 percent). The amount economically available for human use is only 0.007 percent of the total, or about 13,500 km3. This comes out to only about 2300 m3 per person – a 37 percent drop since 1970 (United Nations 1997). Adding complexity to this increasing scarcity is the fact that almost half the globe’s land surface lies within international watersheds (i.e., that land which contributes to the world's 261 transboundary waterways)...go next

Dam building and the threat to indigenous people in Laos

Indigenous communities living along the Sesan, Srepok, and Sekong Rivers rely on the

rivers’ natural resources, along with traditional shifting cultivation for both cultural and

economic purposes. These remote communities have limited access to social services,

lack opportunities to participate in the processes of development and often suffer from

their rights either being violated or not fully respected.

Hydropower dam development along the Sesan, Srepok, and Sekong Rivers in Vietnam

and Lao PDR has been viewed as serious threat to several different indigenous

communities living downstream of these dams in Cambodia. Since the construction and

operation of some hydropower dams, such as the 720 MW Yali Falls dam on the Sesan

River, villagers have experienced large-scale social, economic and environmental

impacts during the last decade. These dam-affected communities are now living with

economic insecurity due to a sharp decline in fish catches and agricultural production, as

well as a fear of the river due to its erratic water-level changes (McKenney 2001)

The basic rights of villagers living along the Sesan River have been violated, such as their

right to life, right to food and water, right to access information, right to participate in

decision making, right to remedy for the loss of life and livelihoods they have suffered,

and right to be protected (NGO Forum on Cambodia 2005). In some cases, villagers are

even abandoning their villages along the river to move into the highlands, because they

can no longer rely on the rivers and its natural resources and are tired of living with fear

that the dam may break or their lives will be swept away in a water surge or flood. One

woman in Pawdal village along the Sesan River summarized her feeling by stating,

“Everyday people are scared of the water, the same feeling as if they have just seen a

cobra or a tiger.”

Dam-affected communities have yet to receive mitigation or compensation for the

impacts that they have suffered from Yali Falls dam. Despite communities’ efforts to

bring this issue to various responsible authorities, i.e. government of both countries, etc.,

dam builders, stakeholders, and governments involved have denied responsibility for the

negative impacts that have occurred along the Sesan River.

In addition to the Yali Falls dam, a cascade of dams is now being planned for the Sesan,

Srepok, and Sekong Rivers in both Vietnam and Lao PDR. Some of these dams are

currently under construction and were planned without people’s participation nor

adequate or complete Environmental and Social Impact Assessments. Full report.

Water insecurity and the poor

Household water insecurity is a pressing problem in developing countries. Unsustainable

water withdrawal is increasing due to population growth, industrialization, urbanization, and

increasing agricultural production which leads to various problems. The number of countries

facing problems of water scarcity and insufficient water supply is rising. Already there are 1.2

billion people without access to clean water, many of whom live in 20 developing countries

classified as ‘water scarce’. Typically it is found in these countries, that the poor pay particularly

high prices for water and are most water insecure.

Progress towards water security can be made only if there is a more comprehensive

understanding of the interactions among waters’ various characteristics and functions. Water is

not only a natural resource, but also an economic commodity, and a human consumption good or

entitlement. The problems of water insecurity can be grouped under three main headings:

availability, access and usage. In the framework of a multidisciplinary approach to the analysis

of water problems, the paper elaborates on these three elements, defining sectoral and cross-

sectoral knowledge gaps. The paper concludes with a research agenda in support of improved

policy design and action.

Some interesting data about Vietnam is available.

Global Warming

Global Warming is one of the most controversial scientific issues of the twenty-first century. This is a problem that has serious economic, sociological, geopolitical, political, and personal implications. This Very Short Introduction is an informative, up-to-date, and readable book about the predicted impacts of global warming and the surprises that could be in store for us in the near future. It unpacks the controversies that surround global warming, drawing on material from the recent report of the Intergovernmental Panel on Climate Change (IPCC), a huge collaborative study drawing together current thinking on the subject from experts in a range of disciplines, and for the first time presents the findings of the Panel for a general readership. The book also discusses the politics of global warming, and looks at what we can do now to adapt to climate change and mitigate its worst effects.

Viet Nam’s response to climate change

Climate change has had a negative impact on nearly all sectors of Viet Nam’s economy, from agriculture, forestry, aquaculture as well as hydro-electric power, oil and gas production and sea transport, said experts at the launch of the UNDP Human Development Report 2007/2008 in Ha Noi on November 28. This year's report warns that poor people in developing countries will be those most vulnerable to the impact of climate change.
