Sustainable agriculture is an important component of many the 17 Development Goals agreed upon by UN in 2015 (https://sustainabledevelopment.un.org/sdgs). However, trend moving opposite, non-sustainable direction. Agriculture one major drivers biodiversity loss. Next to loss due habitat destruction conversion natural lands into agriculture, intensification has led a strong decline specific farmland biodiversity. Furthermore, agricultural landscapes face pollution pesticides and fertilizers,...

Despite their recognized agricultural sustainability benefits, mixed crop-livestock farms have declined in the Northern hemisphere. As such, integration beyond farm level is a promising alternative to this trend, but knowledge of critical factors and strategies towards its successful implementation still lacking. We developed an analytical framework assess determinants emergence outcomes integration, which helped us understand farmers’ collective for reducing transaction costs. The resulting...

Rodent UV-sensitive mutant cell lines of complementation groups 6 and 8 are the genetic counterparts human Cockayne syndrome CS-B CS-A, respectively. The original in this group, UV61, was described as defective cyclobutane pyrimidine dimer removal after high doses UV. We have examined responses several from group to low UV irradiation, find that these mutants wild-type capacity for DNA repair indicated by incision, dimer, (6-4) photoproduct removal. ERCC6, product gene mutants, is implicated...

ABSTRACT Organic production methods have in the past been shown to benefits for environment, biodiversity, soil quality, animal welfare and reduced pesticide residues. In addition these qualities they may also contribute directly human health. an exploratory study, raw (bulk) cow's milk from five organic neighbouring conventional farms were compared at end of winter housing period. Farm management clearly differed; e.g. cows ate less concentrates forage maize, more silage grass clover hay....

Organic agriculture only allows a few 'natural' compounds for managing pests and diseases such as copper which is applied fungicide in apple, grape, potato, tomato production. But heavy metal, under debate the organic sector. One key strategy to replace use market introduction of resistant varieties. In this article, obstacles opportunities new apple potato varieties are identified described. A comparative analysis integrating agricultural, economic, cultural, social perspectives conducted...

Abstract Risk considerations have become increasingly important in nowadays agriculture, due to a variety of reasons. Surprisingly, the practice formalized risk management is not widespread despite huge amount scientific literature on this topic. This discrepancy between science and extension described by many authors. paper presents communicative method, rooted financial economics, evaluate risk-return profiles way that for individual farmers. The method derived from modern portfolio...
