Program Participation and Farm-Level Adoption of Conservation Tillage: Estimates from a Multinomial Logit Model AgEcon
Babcock, Bruce A.; Chaherli, Nabil M.; Lakshminarayan, P.G..
The conservation compliance provision of the 1985 Food Security Act requires highly erodible land to be cropped according to a locally approved conservation plan. There is overwhelming evidence that conservation compliance has reduced soil erosion. A key issue confronting Congress as they consider 1995 Farm Bill options is the fate of these erosion benefits if commodity programs are eliminated or it the subsidy level is greatly reduced. This study provides policymakers with additional insights into the relationship between conservation tillage practices and government programs by using observed farmer behavior. The central question addressed is: If future program benefits are not tied to conservation practices, will there be a significant decline in the...

MANAGING DROUGHTS IN THE LOW-RAINFALL AREAS OF THE MIDDLE EAST AND NORTH AFRICA AgEcon
Hazell, Peter B.R.; Oram, Peter A.; Chaherli, Nabil M..
Drought is a recurrent and often devastating threat to the welfare of countries in the Middle East and North Africa (MENA) where three-quarters of the arable land has less than 400 mm of annual rainfall, and the natural grazings, which support a majority of the 290 million ruminant livestock, have less than 200 mm. Its impact has been exacerbated in the last half century by the human population increasing yearly at over 3%, while livestock numbers have risen by 50% over the quinquennium. Virtually no scope exists for further expansion of rainfed farming and very little for irrigation, hence there is competition between mechanized cereal production and grazing in the low rainfall areas, and traditional nomadic systems of drought management through mobility...

CROP YIELD AND PRICE DISTRIBUTIONAL EFFECTS ON REVENUE HEDGING AgEcon
Tirupattur, Viswanath; Hauser, Robert J.; Chaherli, Nabil M..
The use of crop yield futures contracts is examined. The expectation being modeled here reflects that of an Illinois corn and soybeans producer at planting, of revenue realized at harvest. The effects of using price and crop yield contracts are measured by comparing the results of the expected distribution to the expected distribution found under five general alternatives: 1) a revenue hedge using just price futures, 2) a revenue hedge using crop yield futures, 3) an unhedged scenario where revenue is determined by realized prices and yields, 4) an unhedged scenario where revenue is determined by realized prices and yields and by participation in government support programs with deficiency payments, and 5) a no hedge scenario where revenue is determined by...
