To avoid the current paradoxes of the global agro-food system it is necessary to define and implement a viable agricultural sustainable model, combining satisfaction of food needs and land preservation. A possible solution can be found in a holistic production system consistent with a sustainable development model, designed to satisfy diverse “local” economies. The conservation agriculture (CA) could be a part of this model, as it includes a set of best practices available to preserve agrarian soil and its biodiversity. Briefly, we cover the CA background in Europe followed by the evaluation of its impact in terms of private/public interest, using the sustainability’s metric.To test the viability of a model based on CA in “local conditions”, we compare economic performance of different conservation practices (i.e. minimum and no tillage) to that of conventional agriculture in a typical Mediterranean environment – Collina Materana – in Southern Italy (Basilicata region). Our findings suggest that: i) CA can actually be a viable alternative to conventional systems; ii) in Mediterranean agricultural areas CA has yield advantages especially during dry years, when conservation techniques increase water supply to crops; iii) public support is needed to direct farming choices in fact without financial incentives these practices would be not widely accepted and diffused; iv) European policy makers have to recognized the positive benefits of CA and pay them as ecosystem services in the framework of Good Agricultural Environmental Conditions and the present CAP subsidies. 相似文献

Measuring Farm and Market Level Economic Impacts of Improved Maize Production Technologies in Ethiopia: Evidence from Panel Data 总被引:1,自引:0,他引:1 下载免费PDF全文

While it is often recognised that agricultural technology adoption decisions are intertwined and best characterised by multivariate models, typical approaches to examining adoption and impacts of agricultural technology have focused on single technology adoption choice and ignored interdependence among technologies. We examine farm‐ and market‐level impacts of multiple technology adoption choices using comprehensive household survey data collected in 2010/11 and 2012/13 in Ethiopia. Economic surplus analysis combined with panel data switching endogenous regression models are used to compute the supply shift parameter (K‐shift parameter), while at the same time controlling for the endogeneity inherent in agricultural technology adoption among farmers. We find that our improved technology set choices have significant impacts on farm‐level maize yield and maize production costs, where the greatest effect appears to be generated when various technologies are combined. The change in maize yield and production costs results in an average 26.4% cost reduction per kilogram of maize output (the K‐shift parameter). This increases the producer and consumer surpluses by US$ 140 and US$ 105 million per annum, respectively. These changes in economic surplus help to reduce the number of poor people by an estimated 788 thousand per year. We conclude that deliberate extension efforts and other policies that encourage integration of technologies are important for maize technologies to yield their full potential at both farm and market levels. 相似文献

The allocation of regional policy funds varies dramatically across regions even when one controls for regional development indicators. We investigate the impact of local government performance as well as spillovers in knowledge, financial means and social relations as determinants of regional fund absorption. Government performance is derived within a Data Envelopment Analysis approach. Spillovers are investigated using a spatial Durbin model. Results show that government performance has a positive impact on fund absorption. Spillovers occur in knowledge as well as in financial means. The empirical analyses focus on Special Accession Program for Agriculture and Rural Development in Slovakia using panel data. 相似文献

Agri-environment schemes were introduced in the mid-1980s. Their primary objectives have developed from initially aiming to hold back intensification towards stimulating environmental enhancement. The introduction of Entry Level Stewardship (ELS) in England represents a third stage in seeking to extend the coverage of schemes across the majority of agricultural land. This aims to influence land use along the whole of the intensive margin. The ELS offers a wide range of options for which farmers are awarded points. Selection of options equivalent to 30 points per ha in lowland areas entitles farmers to a payment of £30 per ha. By September 2007, 4.4 million ha had been entered into the scheme, equivalent to 47% of the agricultural area. From amongst the options on offer, 34% of points were for boundary options, 20% for intensive grass options, 16% for management plans and 13% for options taking arable land out of production. The choice of options varies across the country with a higher proportion of the agricultural area entered in the East. Entry into the scheme is associated with total agricultural area, cereals farming, larger farms, a lower proportion of area in Environmentally Sensitive Area and Countryside Stewardship schemes and grazing livestock numbers. While the ELS has introduced a large number of new entrants into agri-environment schemes, the extent of the environmental impact is uncertain. Given the large number of options available, it is likely that farmers will have chosen options that involve relatively little change and incur limited cost. At the same time, it would be surprising if the environmental gains were of the types most valued within local areas. The ELS approach implies that public goods provided from agricultural land should be paid for irrespective of what would have happened in the absence of the scheme. While this may be a fairer approach, it may also undermine the idea of land stewardship and imply that payments will continue to be required in the long term in order to sustain provision. The ELS does establish a framework within which incentives could be targeted to deliver specific benefits within particular contexts and suggestions are made as to how policy might be developed for this. 相似文献

This paper examines the dynamics of the overwhelmingly generous social housing in France that covers a wide spectrum of recipients. Being influenced by electoral power of rotating ruling parties and social ideals, policy formulations are often reflected by idealistic politics which tends to over-stretch the nation’s budget and restrict its scope in reaching its target groups. From the 1990s, fund availability has been further hit by economic globalization causing falling business profitability and high unemployment rates affecting notably ethnic minorities. Upcoming social crisis has been met with public response via a series of technical-led remedial acts to promote social integration in housing and by identifying social ills and polarization in sensitive and problematic urban quarters. New technical and financial measures in coping with the complexity and magnitude of social housing are expected to remain highly challenging in the French parliamentary politics. 相似文献
