More Vietnamese households adopt integrated aquaculture systems as a climate-smart practice
cgiar.org
Coastal communities are learning about the benefits of climate-smart aquaculture and integrated coastal farming systems. More quantitative evidence of these practices is now being documented.
Many coastal communities in Vietnam’s North and North Central Coast (NNCC), one of the poorest regions in the country, rely on coastal aquaculture, particularly integrated aquaculture farming systems for their livelihoods and sustenance. However, climate change and its impacts have negatively affected coastal aquaculture recently by increasing the risks of disease outbreaks and crop failures.
For example, tiger shrimp, the major culture species of many farms in the NNCC, are sensitive to changes in the climate and the environment, such as the salinity level of the water. The shrimp crops are at high risk for failure when the salinity level of cultured pond drops below five parts per thousand (ppt). For farmers, depending solely on one type of crop could therefore be disastrous, especially in the context of increased extreme weather events. Integrated aquaculture systems ensure farmers have more diverse crops on which to depend and earn stable income to enhance their adaptive and resilient capacity to cope with climate change impacts.

10 things to know about the future of water and sanitation
Briefing papers
August 2017
The world is transforming in many different ways.
These shifts – from climate change, to migration, to new technology and urbanisation – will have a significant impact on the management of water resources and related services such as sanitation. This impact will be both positive and negative, throwing up a variety of new opportunities and challenges, for people and economies.
But how can we make the most of the opportunities and face the challenges?
Here, we outline 10 things to know about the future of water and sanitation up to 2030, to do just that.
This publication is accompanied by the working paper Future flows: global trends to watch on water and sanitation. Tiếp tục đọc “10 things to know about the future of water and sanitation”
Long-Term Clean Energy Optimism, Short-Term Caution
December 19, 2017
By Michael Liebreich, Chairman of the Advisory Board
and Angus McCrone, Chief Editor
Bloomberg New Energy Finance
At the beginning of 2017, we drew an analogy between the clean energy sector and the great explorers of the 15th and 16th centuries, embarking on epic journeys, driven by the scale the opportunities they knew awaited them, but facing quite extraordinary danger and uncertainty.
Well, our battle-hardened fleet managed during 2017 to make some good progress towards Eldorado, despite all the storms thrown at it.
2017 looks certain to be the eighth successive year in which global clean energy investment has been in the range of $250 billion to $350 billion; there is a good chance that it will end up a touch higher than last year’s figure of $287.5 billion. Once again, we have seen substantial reductions in the cost of renewable energy, so that 2017 will certainly see another record for new capacity installations.

Clean energy and rare earths: Why not to worry
“Rare earths” are 17 chemical elements with awkward names and unusual properties. Their atomic numbers are 57–71, 21, and 39. Their two subfamilies, one scarcer and hence more valuable than the other, have similar chemistries, so they’re generally found and mined together.
Despite their name, rare earths are not geologically rare but are widely dispersed throughout the Earth’s crust. They are mined in few places and by few firms, though, because they tend not to occur in highly concentrated form. Further raising miners’ costs and risks, the world market for rare earths is modest (several billion dollars a year), volatile, complex, and dominated by China, where not all mines and exports are legal and transparent. One expert concluded that about half of 2015 global production was off the books. Tiếp tục đọc “Clean energy and rare earths: Why not to worry”
What Happened to the Rare-Earths Crisis?
technologyreview_Four years ago, manufacturers fretted that trade controls in China would lead to a shortage of materials used in making an array of technology products. But demand fell more than expected.
February 25, 2015

- Four years ago, some manufacturers worried that they would run up against a shortage of rare-earth elements, which are used to make wind turbines, certain light bulbs, computers, and many other high-tech products. Rare earths actually aren’t rare, but they are found in low concentrations, attached to minerals from which they must be separated. And most of the facilities designed to mine and separate rare earths are based in China, which limited exports of these materials in 2009 and 2010 (see
- ). A 2010 U.S. Department of Energy

- envisioned a possible “critical shortage” of five rare earth elements, especially dysprosium—crucial to the permanent magnets used in wind turbines and motors in hybrid or electric cars—between 2012 and 2014. But such worries seemingly dissipated without much fanfare. Why?

Chuyện tử tế: Phim tài liệu năm 1985
(Theo wiki) Chuyện tử tế là một bộ phim tài liệu Việt Nam của đạo diễn Trần Văn Thủy. Tác phẩm được sản xuất năm 1985 nhưng bị cấm cho tới năm 1987 mới được công chiếu rộng rãi. Được coi là phần 2 của bộ phim tài liệu gây tiếng vang Hà Nội trong mắt ai, Chuyện tử tếtiếp tục là một tác phẩm phản ánh những suy nghĩ của Trần Văn Thủy về cuộc sống và xã hội thời bao cấp. Bộ phim đã khắc họa hình ảnh của những người dân nghèo khổ trong xã hội để tìm ra lời giải đáp cho câu hỏi: “Thế nào là sự tử tế?”. Cả Hà Nội trong mắt ai và Chuyện tử tế đều chỉ đến được với đông đảo khán giả sau khi có sự can thiệp của Tổng bí thư Nguyễn Văn Linh vào năm 1987. Tác phẩm sau đó đã giành giải Bồ câu bạc tại Liên hoan phim Quốc tế Leipzig, Cộng hòa Dân chủ Đức và được nhiều đài truyền hình mua bản quyền để phát lại. Cho đến nay đây vẫn được coi là một trong những tác phẩm xuất sắc nhất của đạo diễn Trần Văn Thủy.

Sun, Wind, and Power Trading, power grid: Diverse causes behind frequency fluctuations in power grids
Date:January 9, 2018 Source:Forschungszentrum Juelich
Summary :The use of renewables like the sun and wind can cause fluctuations in power grids. But what impact do these fluctuations have on security of supply? To answer this question, scientists analyzed different types of fluctuations in several power grids in Europe, Japan, and the USA — and came to surprising conclusions.
FULL STORY
Frequency measurements from 2015 (data: 50Hertz): the power grid frequency fluctuates around 50 Hz in the European grid and exhibits large jumps particularly in the trading intervals of 15 minutes. Usually, the grid frequency is within the yellow area but upward and downward deviations (grey) are particularly likely every 15 minutes.

Our power grid works at a frequency of 50 hertz — usually generated by turbines, for example in hydro- or coal power plants, which rotate at a speed of 50 revolutions per second. “When a consumer uses more electrical energy from the power grid, the grid frequency drops slightly before an increased energy feed-in re-establishes the original frequency,” explains Benjamin Schaefer from the Max Planck Institute for Dynamics and Self-Organization (MPIDS) in Goettingen and lead author of the study. “Deviations from the nominal value of 50 hertz must be kept to a minimum, as otherwise sensitive electrical devices could be damaged.”

Mekong Delta calls for over $340 million investment in tourism and infrastructure
vietnamnet.vn_Localities in the Mekong Delta region have called for investment in 33 projects in the groups of real estate and tourism, with a total investment of nearly VND7.8 trillion (US$343.2 million), along with 45 other projects related to industry, agriculture, processing and logistics infrastructure development with a total capital of VND150 trillion (US$6.6 billion).
Tourism development in the Mekong Delta has not been on a par with its potential.
The figures were introduced at the 5th Annual Mekong Delta Investment Forum (MekongInvest) 2017, hosted by the Vietnam Chamber of Commerce and Industry (VCCI) – Can Tho branch, in collaboration with Mekong Promotion Club (Mekong PC), gathering centres for trade, investment and tourism promotion of 13 Mekong Delta provinces, on October 25.
