European agricultural landscapes, common agricultural policy and ecosystem services: a review

Since the 1950s, intensification and scale enlargement of agriculture have changed agricultural landscapes across Europe. The intensification and scale enlargement of farming was initially driven by the large-scale application of synthetic fertilizers, mechanization and subsidies of the European Common Agricultural Policy (CAP). Then, after the 1990s, a further intensification and scale enlargement, and land abandonment in less favored areas was caused by globalization of commodity markets and CAP reforms. The landscape changes during the past six decades have changed the flows and values of ecosystem services. Here, we have reviewed the literature on agricultural policies and management, landscape structure and composition, and the contribution of ecosystem services to regional competitiveness. The objective was to define an analytical framework to determine and assess ecosystem services at the landscape scale. In contrast to natural ecosystems, ecosystem service flows and values in agricultural landscapes are often a result of interactions between agricultural management and ecological structures. We describe how land management by farmers and other land managers relates to landscape structure and composition. We also examine the influence of commodity markets and policies on the behavior of land managers. Additionally, we studied the influence of consumer demand on flows and values of the ecosystem services that originate from the agricultural landscape.

The sustainability of irrigated agricultural systems under the Water Framework Directive: first results ☆

Abstract The paper reports the first results of the Project WADI (Sustainability of European Irrigated Agriculture under Water Directive and Agenda 2000), funded under the 5th Framework Programme of the European Union (EU). The objective of the project is to evaluate the economic, social and environmental sustainability of European irrigated farming under different scenarios concerning water policy and the Common Agricultural Policy. The methodology relies on scenario analysis combined with farm level mathematical programming models. Two pilot case studies are presented for Italy: cereal farming and fruit farming. According to the first results, the impact of the directive, up to reasonable prices, may be summed up in a minor reduction of water use associated with a sharp decrease of farm income and a significant reduction of employment. Nevertheless, different farming systems may react in very different ways. More detailed local analyses are needed in order to support the design of effective and efficient policies at basin level.

Ex post environmental evaluation of agri-environment schemes using experts' judgements and multicriteria analysis

Assessing the environmental impact of agri-environment schemes (AESs) is complicated by the lack of both specific measurable objectives and dedicated environmental monitoring of the impacts. A methodology to estimate the environmental performance of AESs was applied in nine EU case study areas, and reduced the complexity of scheme structure into elements that were assessed by experts. Multi-criteria analysis (MCA) techniques helped produce aggregated judgements about single objectives or measures. Expert panels assessed the link between environmental measures and objectives by scoring specific criteria that reflect important factors for delivering environmental effectiveness: valid research models for measures (cause-and-effect); quality of implementation by farmers and institutions; extent of participation and degree of spatial targeting. Multi-criteria analysis enabled comparison of the degree to which environmental effectiveness (estimated from the criteria scores) within a scheme was achieved across environmental objectives of different importance. There were considerable differences in overall environmental performance across different case study areas, and the experts’ scores identified scope for improvement in one or more criteria in most measures. Higher priority environmental objectives (as assessed by stakeholders) did not necessarily demonstrate highest environmental performance. We discuss implications for learning how to improve the design and evaluation of AESs.

The potential impact of markets for irrigation water in Italy and Spain: a comparison of two study areas

The viability of irrigated systems in Southern Europe is closely linked to efficient institutional settings and water-allocation mechanisms. A significant, although not widely used, mechanism for water allocation is an intra-sectorial water market. The objective of this paper is to evaluate to what extent water markets may contribute to the improvement of the efficiency of water allocation and to the profitability of irrigated agriculture. The related issues of water allocation among farm types and farm specialisation are also addressed. The analysis is based on a basin-level linear programming model, comparing the situation with and without a market. It includes both fixed and variable transaction costs and estimates their combined effects on market performances. The model is applied in two areas in Southern Italy and Spain, and simulates the behaviour of different farm types, derived from cluster analysis on a sample of farms in each area. The paper confirms that water markets could potentially improve the economic efficiency of water use, in terms of higher profit per hectare, given limited water availability. The potential improvements are associated with a more intense specialisation of farms and are strongly differentiated among farmers, particularly where significant restrictions to water availability occur. This corroborates the expectations of institutional difficulties in implementing water markets. However, the exchanges, and consequently the potential effects of water markets, are heavily affected by the actual level of water availability, as well as the size and the structure (fixed vs. proportional) of transaction costs. The paper calls for a more in-depth analysis of the connections between market performances and institutional settings, as related to the issue of water-agriculture policy design and coordination.

New advances in the integrated management of food processing by-products in Europe: sustainable exploitation of fruit and cereal processing by-products with the production of new food products (NAMASTE EU)

By-products generated every year by the European fruit and cereal processing industry currently exceed several million tons. They are disposed of mainly through landfills and thus are largely unexploited sources of several valuable biobased compounds potentially profitable in the formulation of novel food products. The opportunity to design novel strategies to turn them into added value products and food ingredients via novel and sustainable processes is the main target of recently EC-funded FP7 project NAMASTE-EU. NAMASTE-EU aims at developing new laboratory-scale protocols and processes for the exploitation of citrus processing by-products and wheat bran surpluses via the production of ingredients useful for the formulation of new beverage and food products. Among the main results achieved in the first two years of the project, there are the development and assessment of procedures for the selection, stabilization and the physical/biological treatment of citrus and wheat processing by-products, the obtainment and recovery of some bioactive molecules and ingredients and the development of procedures for assessing the quality of the obtained ingredients and for their exploitation in the preparation of new food products.

The book integrates cross-disciplinary knowledge about agricultural and environmental applications of informatics, connecting science and policy on a subject critical to the present and future quality of life in rural areas

Improving value transfer through socio-economic adjustments in a multicountry choice experiment of water conservation alternatives

This study tests the transferability of the nonmarket values of water conservation for domestic and environmental purposes across three south European countries and Australia applying a common choice experiment design. Different approaches are followed to test the transferability of the estimated values, aiming to minimise transfer errors for use in policy analysis, comparing both single- and multicountry transfers, with and without socio-economic adjustments. Within Europe, significant differences are found between implicit prices for environmental water use, but not for domestic water use. In the Australian case study, alleviating restrictions on domestic water use has no significant value. Pooling the three European samples improves the transferability of the environmental flow values between Europe and Australia. Results show that a reduction in transfer error is achieved when controlling for unobserved and observed preference heterogeneity in the single- and multicountry transfers, providing additional support for the superiority of socio-economic adjustment procedures in value transfer.

How much would it cost to monitor farmland biodiversity in Europe

To evaluate progress on political biodiversity objectives, biodiversity monitoring provides information on whether intended results are being achieved. Despite scientific proof that monitoring and evaluation increase the (cost) efficiency of policy measures, cost estimates for monitoring schemes are seldom available, hampering their inclusion in policy programme budgets. Empirical data collected from 12 case studies across Europe were used in a power analysis to estimate the number of farms that would need to be sampled per major farm type to detect changes in species richness over time for four taxa (vascular plants, earthworms, spiders and bees). A sampling design was developed to allocate spatially, across Europe, the farms that should be sampled. Cost estimates are provided for nine monitoring scenarios with differing robustness for detecting temporal changes in species numbers. These cost estimates are compared with the Common Agricultural Policy (CAP) budget (2014-2020) to determine the budget allocation required for the proposed farmland biodiversity monitoring. Results show that the bee indicator requires the highest number of farms to be sampled and the vascular plant indicator the lowest. The costs for the nine farmland biodiversity monitoring scenarios corresponded to 0·01%-0·74% of the total CAP budget and to 0·04%-2·48% of the CAP budget specifically allocated to environmental targets. Synthesis and applications. The results of the cost scenarios demonstrate that, based on the taxa and methods used in this study, a Europe-wide farmland biodiversity monitoring scheme would require a modest share of the Common Agricultural Policy budget. The monitoring scenarios are flexible and can be adapted or complemented with alternate data collection options (e.g. at national scale or voluntary efforts), data mobilization, data integration or modelling efforts.

From Agricultural to Bio-based Economics? Context, State of the Art and Challenges

The world economy is experiencing dramatic changes.In this context, the concept of bioeconomy (or bio-economy, or bio-based economy) has emerged as a key strategy to match human needs while facing resource efficiency requirements, based on the sustainable exploitation of biological resources. The Italian Association of Agriculture and Applied Economics (AIEAA) is launching a new journal, “Bio-based and applied economics†(BAE). The main questions behind this initiative are: why a Journal on bio-based economics? And, why is it launched by a scientific society of agricultural economists? We will try to answer these questions by briefly reviewing current trends in the evolution of academic responses to past, recent and emerging research needs in the field of agriculture economics and its interaction with the closest fields of economics, building on this examination to single out relevant challenges for future research.

Assessing the role of economic actors in the production of private and public goods in three EU agricultural landscapes

The study analyses the contribution of relevant economic actors to the provision of private and public goods in agricultural landscapes. A method consisting of a multi-sectoral perspective and an integrated approach based on the analytic network process (ANP) and the use of selected local stakeholders is applied. The usefulness of the method is demonstrated in three European case studies in Austria, Italy and Spain. The results show that agriculture and tourism are the sectors that contribute the most and the least, respectively, to the provision of goods and services in agricultural landscapes. Moreover, the results underscore that policy instruments towards such provision need to be targeted differently in different areas and must take into account the different roles of the local actors involved.
