Resource industry specialists Roger Conrad and Yiannis Mostrous are bullish on the agriculture and water sectors; in their model portfolio they already hold 6 stocks in these sectors.

The co-editors of Vital Resource Investor explain, "We see strong underpinnings for continued higher agricultural prices for many years to come." Here's their latest agrculture play: EI du Pont de Nemours (NYSE: DD).

"Recently the United Nations Food Agency warned of civil war in some countries because of global food shortages. With the rapid urbanization of Asian countries, we see a growing global dependence on a shrinking number of food producing nations, particularly with the world adding 78.5 million people each year.

"There will be ups and downs for prices along the way. A throttling back of America's efforts to develop ethanol so extensively or a move to use something besides corn to brew ethanol could take some of the upward pressure off corn prices.

"A real global recession could also cause food prices to back off for a time and it's also possible we'll see some form of US government intervention to curb food prices, particularly as the presidential election develops.

"We are looking for companies that are expanding rapidly in international markets, sporting respectable yields, and offer solid management and a history of big results," says Keith Fitz-Gerald.

In his Money Map Reporter, he says, "There are a few gems out there. And one such company is Celanese Corp. (NYSE: CE).

"Celanese is the world's largest supplier of acetyl products, including acetic acid and vinyl acetate. What's important to understand is that CE makes 'building block' chemicals based on acetate.

"These chemicals are in almost every household in the world. It specializes in making acid products that others use to create things like plastics, cigarette filters, emulsions, alcohols, acetate products and even food ingredients.

"Not only is CE the world's largest supplier of this specialized material; it also enjoys a huge competitive advantage, based on lower production costs and economies of scale. In fact, 95% of CE's products are number one or number two in their respective markets.

For 25 years, Steven Halpern, editor of TheStockAdvisors.com, has surveyed the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is one of 100+ ideas in the Best Stocks for 2008 report.

"My favorite conservative idea for 2008 is Sigma-Aldrich (NASDAQ: SIAL), one of the world's largest providers of research chemicals, reagents, chromatography products, and related products," says Kelley Wright, editor of Investment Quality Trends.

"SIAL distributes more than 100,000 chemical products for use primarily in research and development, diagnosis of disease, and as specialty chemicals for manufacturing.

"The company believes it is the leader in the worldwide market for research chemicals, estimated at about $8.75 billion, with annual revenue growth of 3%-4%. The worldwide market for fine chemicals is estimated at $50 billion, with annual growth of 2%-3%. SIAL projects that it ranks among the top ten players in the fragmented fine chemical industry.

"The company's balance sheet is relatively strong, with a total debt-to-capital ratio of 26.6% as of September 30, 2007. This should allow SIAL to make additional acquisitions and further repurchases of its common stock. SIAL has acquired 83 million (adjusted) of its common shares since November 1999.

"Nanotech has an incredibly broad application spectrum and the sector offers enormous opportunities," explains Gregg Early in The Real Nanotech Investor.

"My conservative favorite for 2008 is Bayer (OTC: BAYRY). Although the stock is up 50% since we first added it to our portfolio less than a year ago, its return isn't surprising given current market conditions.

"Bayer has a number of things going for it beyond its significant incorporation of nanotech into various product lines; it even sells Baytubes, proprietary ready-to-use, multi-walled carbon nanotubes. It's also a big, safe stock.

"But it's still undervalued relative to its pharma competitors. And it's a German company that has the spending power of a euro-based firm with significant exposure in every major developed and developing market in the world.

The BASF Group (NYSE: BF) is the top conservative idea for 2007 from Gregg Early, editor of The Real Nanotech Investor: A Small World of Big Profits. He notes, "BASF is one of the premier chemicals companies in the world and it's well positioned to be the most dominant and influential chemical company of the 21st century.

"Nanotech is to this century what chemistry was to the 20th century -- one of the most pervasive advancements in every aspect of our lives.

"Like penicillin or the transistor, it will take society decades to fully realize the implications. BASF is already well on its way to applying the lessons it has long been learning on this front.
