Inland commercial fisheries management in France

The French fisheries management regime is based on public and private ownership of fishing waters associated with a complex multilevel management system. A total of 730 operational commercial inland fisheries were examined by analysis of thematic interviews and questionnaires. Commercial fishermen are beginning to understand the nature of their own activity and its relationship to the concept of sustainable management. Nevertheless, fishermen have to face two major problems: first, they are poorly represented on decision making bodies where anglers are dominant, and secondly their activities are governed by two separate ministries. Opportunities for future development may lie in decision making at the catchment level.

入世风险与农村现行双层经营制度的变迁

中国加入WTO之后 ,农民不仅要承担其他国家农民所承担的自然风险与市场风险 ,还要承担因现行双层经营制度带来的预期不确定性的风险 ,其根源在于现行的经营制度呈现出极大的“体制锁定”的色彩。要打破这种体制锁定 ,必须两条腿走路 :诱致性创新与强制性创新并举。既精减机构 ,明确政府的责、权、利 ,又扶植与培育农民联合体 ,增强市场创新主体分摊成本的能力与赢利能力 ,从而确保新体制的生命力与竞争力。     

Study on Site-specific Nutrient Management in Cotton Field

The study on the characteristics of spatial variability of soil nutrients and fertilizer recommendations in cotton field under certain conditions of agricultural management was conducted with GIS and systematic approach for soil nutrient constrains. The results showed that of the spatial variability of soil nutrient was greatly related to the management condition of previous crops. Grid sampling and variable rate application technology (VRAT) were the tools that would hopefully increase fertilizer efficiency. The fertilizers were applied where they were needed and at proper rate. Balance fertilization demonstration showed that fertilizer recommendations according to the available nutrient level in soil could decrease fertilizer cost with 657.4 yuan / ha and increase seed cotton yield by 19.8%. A net profit of the balanced fertilization was 5314.9 yuan / ha higher than that of local fertilization practice.
