This study investigates how Pesticide Risk Indicators (PRIs) can be applied to help develop sound economic policies. We modified one of the numerous PRIs proposed over the years, the Environmental Impact Quotient (EIQ), originally developed for the fruit industry, to consider co-formulants and adjuvants. The new formula includes three components representing the externalities of farm worker risk, consumer risk, and ecological risk. It also considers the potential externalities of the use of pesticides on residents living near the farms where these products are used. We applied the modified EIQ to two areas located in central Italy (the Chiana Valley in Tuscany and the Tiber and Upper Tiber Valleys in Tuscany/Umbria), surveying a sample of farms to determine the quantity and types of pesticides used on five crops: durum wheat, soft wheat, corn, tobacco, and olives. After calculating the impact quotient, we used data from a survey conducted in a different Italian region regarding the willingness to pay (WTP) for a pesticide-free environment and determined the WTP for even minimal changes in that quotient. Using those results, we simulated the changes in welfare (calculated as changes in willingness to pay) that would result from modifying the amount of land used for each crop. Our findings indicate that the proposed WTP indicator may have broad utility and that its application may lead to enhanced awareness of the consequences of pesticide use in farming.

In the Alps as in many mountain areas, livestock farming has constituted an important source of income, especially since the Middle Ages. The importance of livestock farming within the Alpine economy has changed over time due to the dynamics of supply and demand combined with evolving environmental, technological and institutional constraints. This paper focuses on the latter aspect and attempts to reconstruct how the relative importance of the production factors of land, labour and capital changed throughout the nineteenth and twentieth centuries in a mountainous area of eastern Trentino. The underlying objective of the investigation is to provide a micro-level empirical basis for hypotheses advanced in the literature regarding the evolution of a crucial sector in the Alpine economy, drawing attention to the long-term role of exogenous and endogenous factors as well as elements of continuity and change. The work is grounded in multiple sources drawn from local archives and official statistics. It demonstrates the flexibility of local communities in managing to sustainably utilize local resources over several periods.

The idea that landscape fulfils many different functions and provides multiple benefits for human society is gaining strength. This new vision of landscape changes both, the interests and the needs of the persons involved and the use and management of the landscape itself. The objective of this paper is to study landscape conservation in a particular mountainous area of Italy, which requires an institutional, non-generic approach. Using the contingent valuation method, we investigated whether there is a relationship between experts’ and casual observers’ evaluations of ten different scenarios in the Leno Valleys. Results show that direct knowledge of the site characteristics increases the awareness of the importance of the site, significantly impacting on conservation choices and strategies.

The promotion of sustainable tourism models has been widely debated; many pages have been devoted to the attempt to provide the subject with a strong theoretical base and coherent structure. This said, it is still the case that, although such frameworks are crucial for the development of appropriate planning and policy instruments, their actual implementation continue to be fraught with difficulties. These problems are exacerbated when sustainable tourism entails development opportunities which require the support of the local community and the management of natural resources which are typically common goods. Under these circumstances, new management structures, which can both satisfy the needs of the local community and ensure the appropriate stewardship of the natural resources, must be created. Management solutions are not always easy to define and often need to be considered within a general framework, based on which individual cases are then formulated. This study analyses the connections between models of sustainable tourism and natural resource management considering the forest landscape case. This relationship is first examined from a theoretical perspective and then within a case study, in order to highlight the dual approach—both general and within a specific context.

The ways in which forests have been used and managed by man have been modified substantially over time in relation to both changes in the economic and social needs of communities and the visions of the world that these have embraced. In recent times, as regards the flows of utility guaranteed by forests, increasing interest has been focused on recreational aspects of the landscape. Such interest derives from both the importance, highlighted by numerous studies, of this aspect and its connection with tourism. The latter phenomenon is undergoing strong growth and is able to trigger important processes of local development. Within this framework, the present study advances some preliminary considerations on the relationships which, from the standpoint of sustainable local development, exist between possible types of tourism and alternative methods of forest management. To this end, it first explores some characteristics of the forest landscape and their possible economic evaluation, in the light of the attributes of excludability and rivalry in consumption. The study then discusses the possible economic role of tourism and the contribution that a suitable forest landscape can make to the sector’s development. Finally, it sets in context modes of forest management and alternative types of tourism development.
