在中国古代史上,西汉前期的农本思想与农税政策所表现出的思想深度及其取得的重大成效在中国历史上影响深远,值得重视和深入分析。这一思想与政策,强化了举国上下的重农意识,充分发挥了财税杠杆对农业的激励作用,调动了农民的生产积极性,极大地促进了农业的恢复与发展,从而开创了中国古代史上著名的"文景之治",成为后来治国的范例。 相似文献

Even though diversified agroforestry systems can provide sustainable livelihoods and a resilient production of different goods, adoption remains limited in Bolivia. We examine major obstacles to agroforestry adoption and possible incentives proposed by farmers and civil-society organizations, and relate them to governance and international mechanisms that might play a role in agroforestry adoption. Market access for produce from diversified agroforestry remains difficult, as does its processing and transport. Moreover, farmers have difficulties in achieving the quantities and homogenous quality demanded by markets in the major cities. But most importantly, farmers and civil-society organizations saw little government support, although ‘ecological production in harmony with Mother Earth’ is prescribed by law and the constitution. Agroforestry farmers needed support most urgently in the initial phase, when investment costs are high and returns low. They suggested affordable credits, subsidies for diversified farming systems, and insurance against fire. We identified important albeit small steps towards developing markets for agroforestry products, but government support – mostly in the form of diesel subsidies, materials, and infrastructure – mainly benefitted large-scale monocultures and cattle ranching. In response to this, interviewees opted for strengthening farmers’ organizations, for demanding support with the help of civil-society organizations, and for disseminating best practices. 相似文献

Family farming in various guises has been the dominant ownership and governance system in primary production over recorded history. This outcome has been controlled by farmers and their families, possibly due to tradition, opportunities, personal characteristics, skill sets and the nature of primary production. Of these, it is hypothesised that the farmers’ personal characteristics play a major part in the choice, and continuance, of current ownership and governance systems. Equally as important, they, and therefore the land ownership system, play a part in the efficiency of production systems and improvement of the biological and production environment.The benefits and difficulties of commonly used ownership systems in Western society are reviewed. Using a sample of New Zealand (NZ) farms, a comparison of the managers’ features for owner/operator, partnership and corporate based systems is presented. There were significant differences in many variables including the farmers’ age, education, number of children, asset levels, years on the current farm, and similar, but more importantly, the farmers in the ownership system groups had differing personal characteristics. Significantly, despite the corporate based farms employing more professional assistance, the profit levels were similar across ownership systems leaving the farmers’ characteristics the main factors correlating with system choice. However, governance systems per se are only marginally correlated with production systems and efficiency.As successive generations of farmers are unlikely to have different characteristics, and corporate based systems continue to exhibit similar profit levels, relatively simple family based systems will continue to dominate farm land ownership and control. The trends suggest family farms will increase in size and involve family conglomerates facilitating the management of larger, and in many cases multiple, farms. While currently there are few differences in biological efficiency between ownership systems, given the efficiency benefits of size and scale, this could well change with the increase of family conglomerates. Relative to increasing corporatisation, the continuance of family based ownership and governance will also be of benefit to the environment. When developing land policies, these highlighted relationships should be taken into account. This study is a first to consider personal characteristics relative to ownership. 相似文献

Designing and evaluating sustainable development pathways for semi‐subsistence crop–livestock systems: lessons from Kenya

Achieving the Sustainable Development Goals (SDGs) in African agriculture requires a better understanding why high levels of poverty and resource degradation persist in African agriculture despite decades of policy interventions and development projects. In this article, we hypothesize that policies need to account for the key features of the semi‐subsistence crop–livestock systems (CLS) in the region to become effective. The semi‐subsistence CLS are characterized by a high degree of biophysical and economic heterogeneity and a complex, diversified production system involving a combination of subsistence and cash crops with livestock. We investigated the potential for interventions proposed by the Government of Kenya to meet the SDGs by 2030. The analysis uses an integrated modeling approach designed to deal with the key features of these systems. A strategy that stimulates rural development, increases farm size to a sustainable level, and reduces distortions and inefficiencies in input and output markets could lead to a sustainable development pathway and achieve the SDGs for rural households dependent on CLS. 相似文献

Using data from the population of Ecuadorian importers, we examine the extent to which the characteristics of their imports relate to their labor productivity. Results indicate that the technological intensity of imports does not explain differences in labor productivity, although the region of origin of imports explains differences in the manufacturing sector, as imported technologies from advanced regions are associated with superior labor productivity. Nevertheless, as technology intensive imports are not associated with superior performance, we argue that importers from developing countries may use foreign technology inexpertly due to the lack of absorptive capacity and the emerging nature of their national innovation system. 相似文献

This is one of the first studies to explore customer retention in reference to the franchisee–customer relationship. A subsequent objective was to examine localization and standardization from a franchise unit and system-level perspective. Data was collected using a self-administered survey based on customers of pet grooming services in Australia. Findings suggest that the addition of a customer retention perspective reveals a greater depth to the franchisee–customer relationship. Importantly, this implies that there are additional factors likely to influence franchisee–customer retention within franchise outlets. We suggest that individual franchise units, in cooperation with local customers, should co-create local marketing initiatives. 相似文献

This paper examines the qualitative, quantitative, and geographical evolution (1987–2012) of the Blue Flag campaign and accreditation process in Spain, a leading coastal tourism destination heading the list of awards. The standard Blue Flag criteria for crowded, developed beaches are now adapting to new demands for natural beaches, but they still fail to capture essential sustainable tourism features, such as limiting user numbers, or preserving and restoring sand ecosystems. Given these shortcomings, some destinations are moving to alternative awards with a higher environmental commitment, such as EMS, ISO14001, and Eco-Management and Audit Schemes (EMAS). A cluster analysis of Blue Flag data for 983 beaches in Spain over 26 years revealed different behaviour patterns: established tourist areas that have always opted for the Blue Flag programme; tourist areas that adopted the Blue Flag early on but replaced it with ISO14001 and EMAS; recently developed destinations applying for the award to boost their tourism promotion; and tourist areas with no well-defined policy that have opted intermittently for Blue Flag. These profiles illustrate the different policies of Spain's Autonomous Regions, and they are useful for tourism managers to verify whether their destination's behaviour pattern contributes to sustainable tourism and matches strategic policies they have designed for them. 相似文献
