Soil Erosion Risk Factors and the Impacts of Diversification on Organic Strawberry Farms along California’s Central Coast

Sterner, Kay 01 January 2017 (has links)
Soil erosion is a major issue that threatens to undermine our current system of agriculture. Due to the fact that this system is in turn the number one cause of erosion, agricultural practices in the United States need to be rethought. This study explores how traditional ideas of erosion risks are related to observed erosion on organic strawberry farms along California’s Central Coast. In addition, diversified farming systems are addressed as a possible solution for the current unsustainability of our farming practices. The data from this research suggest that diversity of crops on farms could be linked to less soil erosion. These results are promising for the future of diversification as a new framework for agriculture.

中國大陸農地利用之研究 / Agricultural Land Use in Mailand China

杜曉杰, Duh, Sheau Jay Unknown Date (has links)
土地問題是中國歷史上統治者最大的難題,因為中國以農立國,而土地又是農業生產中,最重要的生產要素。農地利用受自然資源及人為制度的限制,由於土地的稀少性及不可移動性,使農地利用趨於集約化,科學化。而人為因素則成為影響農地生產力之主因。中共建立政權後,在北農村推動「土改」,「農業合作化」,「人民公社」,「生產責任制」等一連串的土地制度改革,不斷地在土地的所有制度,生產規模,經營管理等問題上輪迴,所有權由地主配為耕者有其到私有公用,公有私用,演變到集體所有,家庭經營的模式,生產規模則由小而大,再由大而小,經營管理則由個體的單獨計劃到個體的統一計劃,再集體的統一計劃,最後又回到集體的單獨計劃。每個改革的成效並不相同,也因此而形成了劇烈的農業週期性波動;而這種週期性波動又與中共的政治運動結合在一起,對農民造成極嚴重的傷害。整體而言,大陸的農地利用下列特點:1.農地不足,人均耕地狹小。2.農業資金與物資之投入長期處於不穩的狀態,時高時低。3.農地利用長期以種植業中的糧食生產為主,是一種求溫飽的發展模式。就目前言,中共農業投資不足,政策穩定度不夠,若要克服以往在農上大起大落的情況,中共必須加強農業投資,並在政策上導入市場機制,同時對土地進行「要素重組」的工作,才能作更有效、充分的利用。
