What to do with mushroom pickers in my forest? Policy tools from the landowners’ perspective

Wild mushroom picking is a growing recreational and commercial activity. In Spain, wild mushrooms legally belong to the landowner, who seldom benefits from trade in mushrooms or from their recreational value. Cultural aspects (tradition, picker-related harms) and economic aspects (costly forestry works, income opportunities) constitute elements of the debate on how to deal with mushroom picking. Through a survey of private forest owners in Catalonia (north-eastern Spain), this paper examines their experiences with mushroom pickers, the factors shaping their related policy preferences and their willingness to engage in mushroom reserves.The results show broad support for introducing mushroom picking norms. A regulation would allow outsider pickers to enter private land, but only under certain conditions, i.e. to comply with socio-ecological rules of the area. Among respondents who support the regulation, active land owners who report instances of picker-related harm (both tangible and intangible) tend to support the establishment of a fee system which could be reinvested into forest management. That is also the position of the respondents who perceive mushrooms as a private right, i.e. they believe to have a legitimate right to exclude outsider pickers and, eventually, to raise revenues from that asset. On the contrary, forest owners who conceive mushroom picking as a free-access activity prefer neither to regulate it nor to charge fees. The option to establish a mushroom picking reserve depends on the landholder being a fee-supporter and perceiving instances of harm. Harm, instead, is mainly determined by the perception of congestion of pickers, which in turn is determined by the mushroom productivity of their forest, their level of privacy protection and their involvement to the primary sector. These findings help policymakers to better understand the logic and sensitivities of forest owners in view of designing mushroom picking policies that can effectively solve picker-landowner conflicts.     

Evaluating the impact of government land use policies on tree canopy coverage

Many cities around the world are experiencing the negative effects associated with not sustaining a sufficient level of tree canopy coverage. Tree canopy provides environmental benefits such as clean water and air, erosion prevention, climate control, and native species habitat and provides economic benefits such as higher housing values and lower energy expenditures. We study local government policies in a large U.S. metropolitan area (the Atlanta Metropolitan Statistical Area) to find which policies perform the best at preserving or increasing urban forests. Empirical analysis reveals that a set of effective tree ordinance clauses, zoning ordinances, and having high quality smart growth projects in the community all help in preserving tree canopy in economically and environmentally meaningful amounts. Other actions, such as simply having a tree ordinance, designating a key management person in charge of tree programs, the presence of a tree board, and multiple communication channels were shown to be ineffective for our data set. Because benefits from tree canopy accrue to the local government's budget, to residents and to business owners, the entire community should gain from the passage of effective policies to preserve their local tree canopy. Estimated economic benefits from preserving tree canopy through an effective set of public policies are in the range of $10–15 million annually in an average county, mostly due to savings on stormwater management.

新一轮收储制度改革导致玉米减产了吗：基于DID模型的分析

2016年中国开始了新一轮玉米收储制度改革,其间经历了临时收储政策取消以及玉米生产者补贴制度建立两个阶段。利用2010～2017年全国31个省份的省级面板数据,基于DID设计,本文分析了此次收储制度改革对玉米生产的影响。本文研究结果表明,收储制度改革对玉米生产的影响具有较强的时间异质性。在收储制度改革的第一年,改革对玉米总产量、播种面积和单位面积总投入均有很强的负向影响;在收储制度改革的第二年,虽然改革对玉米单位面积总投入依然具有较强的负向影响,但是对玉米总产量以及播种面积则呈现出正向影响。其原因在于,对玉米生产者来说,改革第一年没有配套支持制度,玉米种植收益下降;而在改革第二年,以生产者补贴为主的配套支持制度建立,玉米种植收益上升。     

Forest fragmentation reduced carbon storage in a moist tropical forest in Bangladesh: Implications for policy development

Forest fragmentation is continued to be widespread in the tropics resulting in reduced ecosystem services including carbon storage. However, the effect of forest fragmentation is not considered in the current carbon policy. We investigated the effect of forest fragmentation on tree biomass carbon and soil organic carbon (SOC) storage in a moist tropical forest in Bangladesh. Above and below-ground tree biomass carbon were calculated by using widely accepted allometric equations and SOC was measured by sampling soils up to 10 cm depth and analyzing them in a soil laboratory. Results showed that carbon storage in tree biomass was significantly lower in fragmented forests (16.3 ± 1.37 t C ha⁻¹) than in contiguous forests (31.21 ± 2.75 t C ha⁻¹) (p < 0.001). Likewise, a significantly lower SOC was contained in the soils of fragmented forests (17.26 ± 0.83 t C ha⁻¹) than in contiguous forests (21.62 ± 0.78 t C ha⁻¹) (p < 0.001). Thus a total of 36% less carbon retained in tree biomass and soils in fragmented forests than in contiguous forests. Backward multiple linear regression analysis revealed tree density, tree height, tree DBH, height-diameter ratio (H/D) and tree species richness as influential factors of carbon variation in fragmented forests. All these structural parameters except tree species richness were significantly lower in fragmented forests, were positively associated with carbon storage and explained together 69% of the carbon storage variation. These findings suggest that the altered stand structure and tree allometry likely caused reduced carbon storage in fragmented forests and highlight the importance of landscape scale management intervention in the tropics. Here, we provided with the evidence of strong negative impact of forest fragmentation on carbon storage and argue that this effect should be in consideration which is currently overlooked in existing carbon accounting systems for tropical forests.     

Who drives the formation and adoption of the increasing versus decreasing balance policy?—Evidence from a policy process analysis

The “increasing versus decreasing balance policy (IDB)” is an important land use innovation in China and it transfers developmental rights from less productive rural land to more productive urban construction land. Since its initiation in 2000, it was soon adopted in almost all provinces in China. In the process of transferring developmental rights, what roles do different levels of governments play and why? To answer these questions, this research conducts a policy process analysis by combing the methods of process tracing and multi-level event history analysis. It finds that the policy process of IDB is a bottom-up one. The prefectural level governments are the engine of the whole process for they gain direct benefit from the transfer of developmental right. Provincial governments, on the one hand, act as a hub connecting local to central; on the other hand, fail to regulate and supervise the implementation. Central government is pushed by the force from local to enact the policy of IDB but also shows lukewarm support to it with a concern that it might deviate from the Pareto increase and damaged peasants’ wellbeing. This research explores the complicated inter-governmental relations in land policy-making process in China and also proposes policy implication on IDB’s future implementation.     

Dynamics in national agri-environmental policy implementation under changing EU policy priorities: Does one size fit all?

Over the past 30 years, Agri-Environmental Policies (AEP) in the EU have developed with relative national autonomy and according to the subsidiarity principle. The environmental directives represent an increase in EU-level environmental ambitions and challenge the current implementation of EU AEP by creating an increasingly demanding set of regulations with which each member state must comply. National AEP implementation may, however, maintain original characteristics and fail to adopt or transform as EU policy implementation proceeds or when EU policies develop. This creates a potential gap between EU policies and national policy implementation resulting in the ensuing national policy dynamics and adaptations becoming issues of interest. This raises a central question regarding the extent to which national AEP implementation can help us predict whether AEP will be suitable to achieve environmental directive objectives nationally in the future. In this paper, we first investigate the dynamics in the implementation of national Agri-Environmental Schemes (AES) through changes in (i) AES policy objectives over time, (ii) administrative implementation structures, and (iii) administrative policy decision structures in the Netherlands, Denmark, Greece, Austria and Romania. Second, we examine the extent to which various factors have influenced the development of national policies over time. The study identifies development based on the theory of ‘process of institutional change’, i.e. we qualitatively estimate the costs of change based on proposed factors including economic conditions in relation to AES implementation, political institutional capacity, policy legacy, policy preferences, and current discourse. On this background, we identify differences in implementation strategies or outcomes in terms of inertia, absorption and transformation, which are characteristic of the national responses to changing AEP at the EU level. We discuss AES dynamics; whether policy content or structures should be in focus for future policy design and the implications of these findings for the future role of AEP in fulfilling environmental directives and argue why a one size fits all rule does not adequately cover current AES development.     

Why David sometimes defeats Goliath: The power of actors in disprivileged land-use policy networks

Since the 19th century, Danish policies regarding land use in the wider countryside have been strongly influenced by two competing policy networks. In the period 1866–1970, a strong ‘land reclamation network’ was privileged at the expense of a weak ‘nature protection network’. In contrast, during the last couple of decades, the situation has been turned on its head. Here, a strong nature protection network has been privileged at the expense of a weaker ‘land reclamation network’. In each of the above stable periods, however, a detailed case study of decision-making regarding a rejected project shows that sometimes the weaker network is able to defeat a stronger network in relation to concrete project decisions regarding the use of water bodies. Why is it that even very strong policy communities cannot expect to have all projects they support implemented? Adding the concepts of policy venue and policy image [Baumgartner, F.R., Jones, B.D., 1993. Agendas and Instability in American Politics. The University of Chicago Press, Chicago and London] to the rather static policy network approach provides an explanation—a theoretical framework which, for example, can be applied to decisions/non-decisions regarding nature restoration projects in those countries who during recent years have been trying to move beyond water body protection to restoration of water bodies to their natural state.     

An institutional evaluation of sustainable forest management in Flanders

The aim of this paper is to evaluate the existing Flemish institutional framework of sustainable forest management (SFM). The evaluation was performed using criteria and indicators that were based on the four-dimensional structure (discourse, rules, power and actors) of the policy arrangement approach. The data collection and analysis were done using a single representative case. The conclusions of the evaluation are mixed. The introduction of sustainable forest management is hampered by different perspectives on SFM and a fragmented network of many different owners with a clear asymmetrical distribution of trust and power. It is, however, enabled by the way that the most powerful and trusted actors in the network – the forest group and the forest service – have the same perspective on SFM perspective as the government. We expect that SFM can be achieved in the near future, although it remains a vulnerable situation.

Switzerland’s transition from flood defence to flood-adapted land use–A policy coordination perspective

This contribution examines Switzerland’s shift towards integrated flood risk management from a policy coordination perspective. The study applies a heuristic framework of policy coordination to explore how adaption needs promoted cross-sectoral policy coordination between hydraulic engineering and land use planning and enhanced coherence in flood policies targeting extreme flood events. To account for the temporal dimension in policy coordination, the article traces Swiss flood policies back to the early 1800s and distinguishes four phases of policy coordination. Across the four periods, the analysis focuses on (a) the drivers of policy coordination, (b) the manifestation of policy coordination in terms of policy frames, goals, instruments and subsystem involvement, and (c) the performance of policy coordination. Complemented by an in-depth case study of cross-sectoral flood policies in the Swiss canton Nidwalden findings show that the coordination between flood and land use policies has primarily been driven by three factors: (i) extreme floods as focusing events, (ii) an increasing problem pressure, and (iii) strategic reorientations in flood and land use policies. Today, flood risk management in Switzerland displays a high degree of sectoral interplay between hydraulic engineering and spatial planning. By fostering flood-adapted land uses Switzerland’s coordinated flood policies reduce the vulnerability to uncertain future changes in flood risk and strengthen the country’s capacities to mitigate damage in extreme floods events.     

The importance of the institutional environment on multifunctional farming systems in the peri-urban area of Brussels

The influence of local and regional policies on the uptake of multifunctional farming systems is analysed. The conceptual framework of how regional and local policies can influence farmers’ behaviour is empirically verified by analysing data on uptake of diversification and environmental management by farmers located in the Brussels’ peri-urban area. In a two-stage model, farmers’ participation and behaviour to influence local policy-makers is also examined. It has been found among other things that, in a municipality that attaches greater importance to environmental issues, the uptake of agri-environmental measures is higher and that promotion of local agriculture will encourage farmers to start processing or selling products on their farms.

Policy dependency and reform: economic gains versus political pains

Economic analysis condemns market intervention in favour of farmers as inefficient and ineffective, and therefore worthy of radical reform. Practical experience, however, indicates that such lessons are hard to learn and implement. Economic analysis tends to ignore the path dependencies generated by the policy evolution process. Without reform strategies that take full account of these dependencies, policy reform will continue to be reluctant, slow and frequently counter-productive. This paper reconsiders the evolution of farm policies and the economic assessment of their costs and benefits. In so doing, it re-phrases conventional economic arguments in terms which seem to accord better with sensible intuition, which may prove more accessible and credible to policymakers and advisors. The difficulties of reconciling economic efficiency with political acceptability are identified. The paper concludes with a substantial challenge to the agricultural economics profession.     

Is there a forest transition outside forests? Trajectories of farm trees and effects on ecosystem services in an agricultural landscape in Eastern Germany

Most industrial countries have experienced a transformation of land use: from decreasing to expanding forest areas, the so-called forest transition. Outside closed forests, European rural landscapes exhibit a diversity of tree-based agricultural systems, but the question of whether this forest transition has also affected ‘trees outside forests’ has rarely been studied. The aim of this study is to analyze the spatial-temporal dynamics of farm trees and woodlands in an agricultural landscape in Eastern Germany from 1964 to 2008, based on aerial photographs and digital orthophotos. Taking a landscape ecological perspective, we quantify farm tree dynamics, disentangle processes of gain and loss in the socialist and post-socialist periods of Eastern Germany, and assess differences in ecosystem services provided by farm trees. A substantial increase of overall tree cover by 24.8% was observed for the selected time period, but trajectories have been disparate across different farm tree classes. The increase in tree cover was stronger in steep valleys than on hills and plateaus, indicating a significant interdependence between topography and trajectories of change. Patch numbers of farm trees did not increase, which suggests that the expansion of tree cover is mostly due to a spatial expansion of previously existing tree patches. Overall net gains in tree cover were rather similar during the socialist and post-socialist eras. The general increase in tree cover was accompanied by increase in agriculture-related ecosystem service provision, but the increase in pollination and pest control services was much lower than that in water purification services. These findings present the first empirical evidence from an industrialized country that there is also an ongoing ‘forest transition’ outside closed forests. Potential, partially counteracting drivers of change during the socialist and post-socialist periods have mainly been related to farm policies and the environmental consciousness of land users and society as a whole.
