Global demand for treating prostate disorders with Prunus africana bark extract has made P. africana Africa's largest medicinal plant export. Unsustainable harvesting practices can lead to local extirpations of this multipurpose tree. Survey research targeting P. africana harvesters in a Tanzania forest reserve revealed that 78% of them used unsustainable harvesting practices. This research focused on establishing a socioeconomic profile of the harvesters, the profitability of their business operations, and identifying the factors that influence their selection of harvesting practices. Results indicate that harvesters have above-national-average education, double the average family size, and generate income exceeding government's minimum wages. Large family size and high earning potential imply increased future harvesting activity. Logistic regression results indicate that education and training level could predict the likelihood that a harvester would use unsustainable harvesting practices. Local- and district-level government organisations could implement a resource assessment as a basis to design and implement harvesting schedules and ensure that the harvesters receive appropriate training, regardless of their education level. 相似文献

许可实施是植物品种权实施的主要模式之一,是将创新品种转化为利润的重要机制,能够激励植 物新品种研发创新,并促进新品种技术扩散。植物品种权许可实施不同于品种权转让,具有收入效应和竞 争效应,从微观角度可以提高知识资产的使用效率。但是植物品种权许可实施的收入效应和竞争效应受复 杂因素影响,由于信息不对称和不确定因素的存在,许可双方无法事先签订完美的许可合同。品种权人可 以通过许可合同价格条款和许可范围的选择,利用“入门费 分期提成/阶段性支付”的许可费用模式, 规避许可风险。 相似文献

Economic growth and income distribution are two of the major subjects in international economic studies. Perforce theory believes that inequality improve growth. Endogenous economic growth theory shows that inequality is harmful for growth. After summarizing western theory on growth and income distribution, this paper gives the detail survey of relationship between income distribution and growth, and the mechanism of the effect is discussed. 相似文献

This study aimed to investigate a cultivar selection criterion based on income ha−1 in common wheat. Regional yield trials with 20 entries were planted in Diyarbakır, Hazro and Ceylanpınar in southeast Anatolia in the 2004/2005 growing season. A randomized complete block design with four replications was employed. Grain samples from each location were subjected to quality analyses, and then presented to randomly selected grain purchasers with the local commodity market for market price estimations. Entries 1, 9, 10, 7 and 6 were the top five ranking entries for grain yield, giving 5,320, 5,290, 5,280, 5,140 and 5,130 kg ha−1, respectively. From the market price perspective, entries 17, 3, 7, 20 and 8 received the five highest marketing price offers with the values 239.0, 238.1, 237.1, 236.9 and 236.7 US$ tonne−1, respectively. There was a US$ 10.94 tonne−1 market price difference between entries with the highest and the lowest market price. The only quality analyses showing significant correlations with market price were Zeleny sedimentation value and hectolitre weights (kg hl−1). From thev production income [= marketing price (US$ tonne−1) × grain yield (kg ha−1)] point of view, entries 9, 10, 1, 7 and 6 were ranked from 1st to 5th for production income ha−1 with the values 1,241.0, 1,238.0, 1,219.9, 1,214.2 and 1,209.3 US$ ha−1, respectively. All five high yielding entries were also high-income entries. A rank stability analysis further indicated that entry numbers 6, 7, 8, 4 and 1 stable for high production income ha−1. A simulation study, based on allocation of additional premiums for high quality indicated that entries 9,1,10, 7, and 6 would be top ranking for high income ha−1 if given an additional premium of as much as twice the standard deviations of market price for each entry (the highest premium limit; 20.24 US$ tonne−1). The order for cultivar preference for high production income ha−1 would change and would generate 1,321.94, 1,296.20, 1,281.11, 1,258.06 and 1,243.01 US$ ha−1, respectively. It was concluded that the relatively quality conscious Şanlıurfa commodity market does not offer adequate premiums for the high quality grains. This results in farmer preference for high yielding lower quality cultivars. Even though quality cannot be neglected, and cultivar preference could change with additional premiums, breeders must give more attention to high production income ha−1. 相似文献

Improving national average income and reducing regional income inequality often serve as dual goals of economic development in a country. After over twenty years of economic reforms, China has been fairly successful in achieving the first goal, but failed in the second. This paper uses recent data with a sharper resolution to examine the variation of average wages across Chinese cities 1989–1997. Widening wage inequalities across cities are observed during the period. This research also seeks to explain the variation of wages between cities by factors such as agglomeration (density and city size), location advantages (distances from central cities and from the coastline), educational attainment, industrial structure and administrative hierarchy. Many of the factors are found to be important in explaining wage differences in Western countries but are yet to be tested in China. Some factors such as distance from the coast, industrial structure and administrative hierarchy are considered because of China’s unique social and economic systems. 相似文献
