This paper presents some results from a survey carried out in 2004 among 223 olive tree farmers from mountainous areas in the Spanish Southern provinces of Granada and Jaén regarding the adoption of soil conservation and management practices. Olive tree groves in mountainous areas are subject to a high risk of soil erosion and incur a higher cost of soil conservation. This results in greater di...
Conservative agriculture is considered as an alternative to tackle the need for increased agricultural production based on sustainable agriculture activities with the aim of increasing production and product stability along with preserving the environment. Tillage is one of the most important factors affecting soil structure. Selection of appropriate tillage systems varies according to the cond...
Soil erosion is one of the most important forms of land degradation that threatens continued and sustained agricultural production in Ghana. The most severely affected areas are the three northern regions especially Upper East Region, where large tracts of land have been destroyed by water erosion leading to soil depth reduction and decline in soil fertility. This study was carried out in Talen...
Soil erosion poses economic and environmental concerns in many tropical uplands. Agroforestry has been proposed as a sustainable land use that can mitigate soil erosion and promote the economic welfare of small farmers. To evaluate such claims, we must (a) develop a composite measure of effectiveness, such as a soil conservation index, and (b) define it in terms understood by the farmers who ul...
It is important to indicate at the outset that I do not intend to argue for more funding for soil conservation programs, but rather for more efficient use of the resources presently committed. Before we can go very far in evaluating the impacts of soil conservation spending changes, we need additional background on soil conservation programs. It is hoped that such information will tell us somet...
land degradation due to soil erosion has been well pointed out as one of the most serious ecological and economic problems that some such south asian countries including iran are faced with. although high investment has been made, particularly in introduction of soil conservational mechanical practices, the level of acceptance of these practices has been low and while a high rate of erosion con...

Soil conservation efforts in Indonesia since the Dutch colonial era have focused on introducing bench terraces—a costly soil conservation method for poor, upland farmers. Data from two villages in the Kerinci uplands of Sumatra illustrate that even with state underwriting of bench terrace construction, farmers across all economic strata still resist using this method. Why the state has not purs...
