Producer--scrounger models are used to explain the tactics of socially foraging animals where individuals can either search for their food (produce) or join the food discoveries of others (scrounge). However, the empirical testing of such models has generally been restricted to indoor aviary...

This paper attempts to rank agri-environmental measures based on their long-term contribution on biodiversity conservation and ecosystem services as well as on net income received from agriculture and forestry. Environmental fallows proved to be a cost-effective measure in promoting bumblebee...

In der vorliegenden Stellungnahme werden die GAP-Beschlüsse zum Greening der Direktzahlungen in Bezug auf die nationalen Gestaltungsspielräume für die drei Greening-Komponenten Anbaudiversifizierung, Erhaltung von Dauergrünland und ökologische Vorrangflächen (ÖVF)2 bewertet und...

There is mounting evidence of pollinator decline all over the world and consequences in many agricultural areas could be significant. We assessed these consequences by measuring 1) the contribution of insect pollination to the world agricultural output economic value, and 2) the vulnerability of...

The ‘cascade model’ of ecosystem service generation and valuation highlights the links between biophysical aspects/biodiversity and human well-being, in particular for the case of marginal changes, but does not include societal processes. Services seem to flow effortlessly from ecosystems to...

One of the key challenges in designing agri-environmental schemes targeted at conservation is the determination of the amount of financial resources that should be allocated towards a particular aim such as the conservation of an endangered species. Economists can contribute to an answer by...

Designing agri-environmental schemes targeted at conservation poses the key question of how many financial resources should be allocated to address a particular aim such as the conservation of an endangered species. Economists can contribute to an answer by estimating the 'optimal level of...

An approach is present which integrates an economic and an ecological model for designing cost-effective compensation payments for conservation of endangered species in real landscapes. The approach is used to develop a cost-effective compensation payment scheme for conservation of an endangered...

Mapping of ecosystem services’ (ESS) values means valuing ESS in monetary terms across a relatively large geographical area and assessing how values vary across space. Thereby, mapping of ESS values reveals additional information as compared to traditional site-specific ESS valuation, which is...
