Enhancing Resource Management in Socio-Ecological Systems: Modeling Collective Conditionality in Rural Policies
No full textThe collective approach toward natural resource management in agriculture is increasingly gaining attention, by both the literature and policy makers. In the thesis I analyse the implementation of collective approaches in rural policies aimed at natural resource management. More specifically, I analyse how two design elements of this type of policies, collective conditionality constraints and subsidy levels, affect the 1) emergence of cooperation among farmers and 2) the distribution of the benefits. In the analyses I address the effect of these policies in a range of situations, namely in case the action subsidized by policy is a public good, a club good, or only a private cost (and thus cooperation is purely linked to the implementation of the policy). The distributional effect is addressed only in the club good case.
The results show that indeed the proper use of collective conditionality constraints associated to subsidies can improve the cooperation of farmers and thus leading to more effective agri-environmental policies.
It seems that the collective approach for natural resource management is a strategy that deserves higher attention and policy effort. However, it should not be taken lightly or naively implemented, as the "sophistication" of mechanisms also increases the scope for unexpected policy outcomes. A more aware implementation of such strategy also requires a greater, inter-disciplinary, effort for research, towards a proper understanding of actual effects of real life policy options and coordination mechanisms
Agri-environmental Policies and Public Goods: An Assessment of Coalition Incentives and Minimum Participation Rules
No full textAn increasing number of papers analyse the inclusion of collective/spatial conditionality constraints in agricultural policies dealing with natural resource management. In this article we theoretically assess the conditions in which employing collective conditionality constraints linked to incentives better reach the social preferences on PG provision by agriculture. We deal with this issue by using a coalition formation model to endogenize the size of the group of farmers cooperating, and investigate how it is affected by different policy schemes. We analyse and compare the following policy schemes: (1) a homogenous payment that target the whole population of farmers, (2) a coalition bonus, that incentivizes only the contributions by the coalition members, and (3) a coalition bonus associated to a MPR on the size of the coalition. The results show that formulating payments that discriminate between co-operators and free-riders, and associating to such a payment a MPR, is relatively more effective than the traditional homogenous payments. However this is true only under some (local) conditions that we theoretically derived
Irrigation reservoirs as blue clubs: Governance and policy intervention
Full text linkReservoirs are increasingly deemed to be important given their potential control of water availability across seasons, from wet to dry seasons, especially given the concerns on the effect of climate change. In this paper, we assess the potential scope for policy intervention on the construction of irrigation reservoirs and its design, focusing on the collective action aspect. We formulate a theoretical model in which farmers pool resources to construct a collective reservoir. We conceptualized the reservoir as a “blue club” that increases the potential water availability in dry season, thus improving water safety for the whole society. We determine the societal potential inefficiency in club size and the policy measures to correct it, focusing on two different club access rules (open vs closed membership). Results show that linear subsidy are ineffective in case of closed membership, and minimum participation rules are required to increase the club size
Agglomeration bonus and endogenous group formation
Full text linkAgglomeration bonus schemes are envisioned to incentivize the connectivity of habitat conservation across landowners. Assuming full cooperation among landowners at the landscape scale, the bulk of the literature theoretically finds that agglomeration bonus schemes are more cost effective in achieving biodiversity conservation than spatially homogenous payments. However, it may be rational for landowners not to cooperate all together but, rather, to cooperate within smaller groups. Here, we analyze the cost effectiveness of agglomeration bonus schemes when such partial cooperation is allowed, that is, when cooperation is endogenously chosen. We introduce a spatially explicit ecological-economic model within a coalition formation game to assess how landowners form stable coalition structures and how this affects biodiversity conservation under a wide range of (i) degrees of spatial cost autocorrelation, (ii) bonuses and flat-rate payments, (iii) species dispersal rates, and (iv) coordination costs. We find that agglomeration bonus schemes are more cost effective than homogenous payments only for low public expenditures. This condition is not identified if full cooperation is assumed. We find, however, that full cooperation never emerges and hence that such an assumption leads to an overestimation of the cost effectiveness of agglomeration bonus schemes. Moreover, we find that the cost effectiveness of agglomeration bonus schemes increases when the spatial cost autocorrelation and species dispersal rate decrease. Finally, coordination costs do not affect the cost effectiveness of the agglomeration bonus scheme but they have implications for its design because of their impact on coalition formation
Farmland abandonment, public goods and the CAP in a marginal area of Italy
Full text linkLand abandonment is affecting several areas of Europe, and the issue has since some years become a policy objective. The consequences of land abandonment are however difficult to assess as both agriculture and land abandonment are linked to socio-environmental public goods, but the relationship between public good provision and land use, as well as their societal value, are unclear and debated. Policy such as the Common Agricultural Policy affects land abandonment and public good provision in different ways, by providing income support and targeting the provision of environmental public goods.The objective of the paper is to assess the land use, public good levels and welfare deriving from agricultural production and from the provision of three selected PGs, in three alternative scenarios. In a reference scenario land use allocation is driven by the maximization of agricultural income; we then compare these results with a scenario where land use decisions maximize the societal welfare, hence including the value generated by the three, and with a scenario that simulates Measure 13 of the Rural Development Programme (payment for Areas Facing natural or other specific Constraints). The method used is a land allocation model calibrated for the hill and mountain area of the province of Bologna (Italy), in which the public goods societal values are the results of a choice experiments taken in the Emilia-Romagna region. The main results is that the societal optimum is reached through a substantial change in land allocation (e.g. a strong reduction in land abandonment and an increase in forest areas) and in the composition of the welfare (from private agricultural income toward public good benefits) with respect to the private optimum. Moreover, generic income support reduces land abandonment but also total welfare as it has negative effects through the reduction of carbon sequestration and increase in soil erosion. More targeted policies, that more explicitly connect support to public good provision, have better welfare effects
Perceived benefits from reclaimed rural landscapes: Evidence from the lowlands of the Po River Delta, Italy
Full text linkThe attention towards residents' perceptions of ecosystem services for an efficient management of rural landscapes is gaining momentum. One noteworthy aspect is the identification of links between perceived supply and societal demand of ecosystem services, as they can disclose leverages to improve rural policies. The objectives of this study are: i) to assess residents' perceptions of ecosystem services attributed to typical landscape elements; and ii) to characterise the perception of different groups of residents. We present the results from a residents' survey based on a phone-questionnaire carried out in a reclaimed coastal area, where vulnerabilities such as anthropic impact legacies and natural hazards are exacerbated. The aim of the questionnaire concerns the collection of information regarding people perception of benefits attached to a set of rural landscape elements and demand for services. The results show that awareness of regulating functions, the presence of disservices and the link with local food production relate with residents' perception of benefits from landscapes. Furthermore, we note that local landscape and the meaning attributed to historical land reclamation initiatives has a lasting influence on the perception of ecosystem services and that of such perceptions are significant for the design of land use policies
Multivariable approach for wear evaluation on long term hip implants retrievals: preliminary results
No full textCooperative Management of Ecosystem Services: Coalition Formation, Landscape Structure and Policies
Full text linkA growing body of literature shows that full-cooperation among farmers to manage productive ecosystem services would yield gains with respect to uncoordinated approaches. The public good feature of these ecosystem services may, however, hinder the emergence of a cooperative solution at the landscape scale. In this paper, we introduce in a coalition formation game a spatially-explicit bioeconomic model of fruit pollination, where pollinaton depends on the distance to the choosen location of natural habitats. We analyse: (i) which coalitions are stable; (ii) what benefits they provide; (iii) how cooperation depends on the initial landscape structure; and (iv) how policy instruments affect cooperation. The theoretical model presents the rationality of cooperation but, due to the detailed heterogeneity and complex spatial interactions among farms, we use a numerical example to determine the stable coalitions. We find that only small coalitions are stable and that the benefits of cooperation decrease when the spatial autocorrelation of fruit tree covers increase. Policy instruments can increase the interest for cooperation but per-hectare payments and minimum participation rules may reduce the habitat area at the margin (by decreasing the stability of coalitions). Price premium for the coalition members increase the habitat area but its budget-effectiveness decreases as the spatial autocorrelation of fruit tree covers increase
In search of factors determining the participation of farmers in agri-environmental schemes – Does only money matter in Poland?
Full text linkThe growing awareness of the negative impact of agriculture on the natural environment creates social expectation towards the reduction of this impact through the pro-environmental activities of farmers. Agri-environmental programmes are one of the key instruments of EU agricultural policy aimed at encouraging farmers to do so. Due to their voluntary nature and involvement of farmers in these activities, there has been a scientific discussion for a long time on the factors determining the participation of farmers in these programmes. Numerous analyses carried out mainly for agriculture of Western European countries, do not give unequivocal answers on the factors which influence the involvement of farmers in agri-environmental measures, which additionally might be different for Central-Eastern Europe. This is a significant problem for policymakers deciding on the distribution of financial support. Our analysis of 594 commercial farms, a subsample of the Polish FADN (Farm Accountancy Data Network), uses both FADN data and the outcomes of interviews with farmers. Results show that farmers who see a clear economic interest for their farm, most often participate in AES (Agri-environmental Schemes). Risk aversion turned out also to be an important determinant but is rarely analysed in the literature. On the other hand, factors related to the attitudes of farmers towards the environment have a small impact (if any) on participation. This is important information for policymakers, as it indicates the educational needs in terms of farmers' understanding of the relationship between farming and the environment, and also indicates that moving away from the model of incentives based on financial incentives would probably involve a reduction in the scale of agri-environmental measures by farmers
