Few people think of Saudi Arabia as a farm country, but agricultural production reached 1.5 billion last year and is on the rise.    Tomatoes, squash, potatoes and lettuce are grown in the desert, and there are large fields of wheat.    In many cases the fields are watered by long irrigation arms that revolve on huge electrically-driven wheels.

Water comes from rainfall, ground-water or wells.    There are 15,000 sq.km. of arable land in the kingdom, only 6000 sq.km. of which are under cultivation.

Recent investigations have confirmed sufficient underground water reserves to support a century of sustained withdrawal, irrigating an additional 600,000 acres (242,000 hectares).
Between 1975 and 1980, 12 commercial dairy farms were established, making fresh milk available in commercial quantities for the first time.    An additional 16 dairy farms will be in operation by 1985, producing 500,000 tons of milk a year, and making the kingdom almost self-sufficient in this important commodity.

Due to heavy subsidization, Saudi Arabia may also achieve self-sufficiency in wheat production by the end of this year.    Domestic yield reached 400,000 tons in 1982 with 600,000 tons expected this year.    By 1985, and additional 144,000 acres will be placed in cereal production.
The 1982 harvest yielded 10,000 tons of potatoes and 77,000 tons of dates, of which 500 tons were exported.

Saudi farmers are having considerable success raising cucumbers and tomatoes in enclosed humidity-controlled conditions.    Using these hydroponic techniques, they are able to harvest such produce in five to eight weeks after transplanting.

Experiments are also provided the domestic market with 80 million chickens last year, 29% of national consumption, and 1.1 billion eggs, 90% of local requirements.

The Saudi government's incentives to invest in the agricultural sector are unusually attractive: the Saudi Arabian Agricultural Bank offers interest-free loans on 80% of the cost of a project up to 15 million.    Fertilizers and animal feed are eligible for 50% of cost subsidies, and selected farm equipment, subsidies of 30 to 50% of the cost.

The airfreight for flying cattle into the country is paid for by the government, as is water for irrigation.

As of October 1982 the Agricultural Bank had made loans amounting to US '1.75 billion.
During the current five-year plan the government is investing US '2.4 billion in the agricultural sector.

From its headwaters at San Ygnacio, Texas, to its giant hydroelectric dam 50 miles downstream, Falcon Lake covers some 87,000 acres the Rio Grande and the U.S.-Mexican border.    Created in the 1950's to improve flood control and irrigation, the lake is a water monument to the era of gigantic public works.    But the worst drought since the Eisenhower years has lowered the water level by nearly 50 feet__and bit by bit, Falcon Lake is revealing the secrets of its long-submerged past.    On the Texas side of the lake, drowned border towns like Zapata and Lopeno, relocated when the dam was built, are reemerging from the flood.    On the Mexican side, near the town of Benevides, stone crosses in a once submerged old cemetery rise like eerie sentinels to the drought.    The last time anybody saw these graves, segregation was the law of the land, the Dodgers were still in Brooklyn and Bill Clinton was in second grade.

The two-year drawdown of Falcon Lake is only one symptom of the Drought of '96 -- a slowly gathering crisis that is putting a huge strain on the water supplies of the fast-growing cities of the Southwest and on the farm-and-cattle regions of the southern Plains as well.    From Los Angeles to Corpus Christi, from Brownsville to Nebraska, the drought pits state against state, city dwellers against farmers and farmers against a global weather system that has turned suddenly hostile toward man.    Severe to extreme drought conditions now prevail across the whole southwestern part of the United States, a region that includes southern California, southern Nevada, all of Arizona, New Mexico and Texas and most of Utah, Colorado and Oklahoma.    The drought has afflicted some parts of the region for up to five years and other areas for as little as 10 months.    But whatever its duration, climatologists agree there is no end in sight.    "The expectation is that this thing is going to continue through the summer and into the fall," says Dr. Don Wilhite of the National Drought Mitigation Center in Lincoln, Neb.    "Beyond that, it's anybody's guess."

What's going on here experts like Whilhite say, is a reverse E1 Nino effect.    E1 Nino ("the Christ Child") is a huge weather system in the western Pacific that, in a good year spawns welcome winter rains in the southwestern states and the Plains.    When E1 Nino does not appear -- and last year he didn't -- the result is even less rainfall in a region that is naturally among the fries in the world.    From August 1995 to May of this year, much of the Southwest and the southern Plains region recorded virtually no rainfall or show.    That dried out the soil and set the stage for a deepening drought.

In Texas, Oklahoma, Eastern Colorado and Western Kansas, the lack of rainfall fairly crushed the 1996 winter-wheat crop.    It also led to a significant shortfall in the supply of cattle feed, which forced many ranchers to cut back their herds.    "Cattle is a US '5 billion-a-year industry in Texas," says Texas agriculture commissioner historic proportions," Perry says the damage to Texas agribusiness has already reached US '2.4 billion and could rise to US '6.5 billion -- which would make the '96 drought the most costly natural disaster in the state's history.
