The greatest challenge for agriculture is to reduce the trade-offs between productivity and long-term sustainability. Therefore, it is interesting to analyse organic agriculture which is a given set of farm practices that emphasise ecological sustainability. Organic agriculture can be characterised as being less driven by off-farm inputs and being better embedded in ecosystem functions. The lit...
Many different actors have hopes and aspirations for the future of organic agriculture. They have different perspectives on organic agriculture with different understandings of what it is and what makes it move. Each perspective entails a certain understanding of organic agriculture featuring certain concepts and values and a particular logic or rationality. It is important to acknowledge this ...

To promote global food and ecosystem security, several innovative farming systems have been identified that better balance multiple sustainability goals. The most rapidly growing and contentious of these systems is organic agriculture. Whether organic agriculture can continue to expand will likely be determined by whether it is economically competitive with conventional agriculture. Here, we ex...
nowadays, thousands tons of chemicals material are used to increase agricultural production that provides a risky situation for the communities. recently, biological or organic agriculture is considered to get rid of such problems. but this style of agriculture is facing with many difficulties and challenges. this study was performed in three phases by using delphi method. in this regard, the s...
Organic agriculture can contribute to meaningful socio-economic and ecologically sustainable development, especially in poorer countries. This is due on the one hand to the application of organic principles, which means efficient management of local resources (e.g. local seed varieties, manure, etc.) and therefore costeffectiveness. On the other hand, the market for organic products – at local ...
This paper presents a world map of organic agriculture. A Gall-Peters projection map of the world is taken as the reference map (where map areas are proportional to territorial areas). Applying the area of organic agriculture to countries, the World Map of Organic Agriculture presents countries as proportional in size to their share of the total of world organic hectares (such a map can be refe...
In this paper, we consider the effect of increasing the area of agricultural land under organic practises. We assumed that organic agriculture does not have effective means of pathogen control. We model pathogen dispersal with a diffusive logistic equation in which the growth/death rate is spatially heterogeneous. We find that if the ratio of the organic plots to conventional plots is below a c...
Biocontrol, or Biological Control, can be defined as the use of natural organisms, or genetically modified, genes or gene products, to reduce the effects of undesirable organisms to favour organisms useful to human, such as crops, trees, animals and beneficial microorganisms. This strategy of control is ecologicaly clean and compatible with different models of agriculture: organic, biological a...
Urban agriculture (UA) has a long tradition in many countries worldwide, is actively engaging about 800 million people, and is now increasingly considered by urban planning and land-use personnel. Urban cropland, in particular, covers more than 67 Mha or more than 5% of the total global cropland area. Urban agriculture practices have many benefits and, in particular, may contribute to food secu...
