The issue of assessment of absolute and comparative sustainability of major farming structures is among the most topical for researchers, farmers, investors, administrators, politicians, interests groups and public at large. Despite that practically there are no assessments on sustainability...

The issue of assessment sustainability of agricultural farms as a whole and of different type is among the most topical for researchers, farmers, investors, administrators, politicians, interests groups and public at large. Despite that practically there are no assessments on sustainability...

This paper attempts to give answer to some important questions, on which there is no agreement among researchers, namely: "what is farm sustainability?", "what is the relation between farm and agrarian sustainability?", "which are critical factors of farms sustainability?", and "how to assess...

Sustainable intensification measures promise ecological improvements of farming while maintaining profitability. That is, farms should be able to produce at a higher ecological efficiency without losses in economic efficiency. Based on a theoretical framework, we investigate this promise...

This article presents a holistic approach for assessing agrarian sustainability in Bulgaria based on its economic, social and ecological aspects on sectoral macro-level. It is based on official statistical and other information as well as on expert evaluation. Our study has found that the...

Do transgenic crops cause agrobiodiversity erosion? We hypothesize that they increase productivity and reduce production risk and may therefore reduce farmer demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesize that varietal...

We analyze the effect of environmental uncertainties on optimal fishery management in a bio-economic fishery model. Unlike most of the literature on resource economics, but in line with ecological models, we allow the different biological processes of survival and recruitment to be affected...
