Soil erosion in developing countries is a widespread problem causing considerable economic damage. It still remains an intractable problem in many countries. Available research findings on costs of soil erosion indicate them to be high. Soil erosion continues to be a problem due to the difficulties of estimating the economic damages and attendant difficulties in developing effective control pol...

The Ricardian model is a widely used approach based on cross-sectional regression analysis to estimate climate change impacts agricultural productivity. Up until now, researchers have focused the of gradual changes in temperature and precipitation, even though known encompass also severity frequency extreme weather events. This research investigates impact heatwaves European agriculture, additi...

This paper investigates and analyses social farming in the Aosta Valley, a tiny Italian mountain region Alps. It aims to highlight features of this region, focusing on mission economic sustainability.The first presents literature farming, marginal remote areas, illustrating main characteristics farms. Secondly, it focuses findings coming from qualitative investigation three case studies Valdost...

As a long term bidding behavior, bid shading is exhibited by wind farms participating in real Uniform Price (UP) markets. This signifies that the wind farm owners bid far below their true long run marginal cost. In this paper, a method is proposed to consider the uncertainty of bidding admission in the long term expected revenue of wind farms. We show that this consideration could perfectly exp...

This study analyses anaerobic digestion (AD) as a renewable energy technology by quantifying the emissions avoided and the cost incurred in the process. The quantitative model developed and demonstrated uses basic farm information to evaluate dairy farms from an environmental and economic perspective. Based on the cost of installing and operating an anaerobic digester and the emissions avoided ...

In Year 1, there are only ten factories, which can employ a maximum of 100 workers. Hence most farms will still have all five siblings working there. The total farm income will be $100, so the average product of labor is $20 = 100 5 . The marginal product is 0, since when there are at least three siblings working on the farm, any additional worker does not increase farm income. Consequently two...

INTRODUCTION Afforestation activities in the Lower Mississippi River Alluvial Valley (LMRAV) are currently peaking after the past four decades of extensive deforestation (Allen 1997, King and Keeland 1999, Stanturf and others 1998). Different forces drive the afforestation efforts of public resource agencies, conservation organizations, private corporations, and private landowners. Their intere...

Five common tetracycline resistance genes tet(A), tet(B), tet(M), tet(O) and tet(S) were studied by polymerase chain reaction in 100 bacteria isolated from Iranian fish farms. In the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. Nine isolates out of 46 Aeromonas spp. contained either tet(A/M/S) resistant genes as follows: tet(A) in A. ...
