identifying role of extension system in adoption of new technologies have important role to developing favorable extension systems. for supporting sustainable agriculture in iran needs extension systems to be carefully thought and accurately implemented. the purpose of this is analyzing role of extension activities in adoption of sustainable agriculture. based on the results the attending agric...

Effective governance of agricultural systems is needed for achieving goals food security, resilient systems, and addressing the impacts climate change. Local governments have an increasing interest in role agriculture meeting these goals. However, alignment varies greatly between local governing systems. Governability a measure degree to which system can be governed set specified purposes or To...

This paper presents a case study of resilience theory to understand agricultural systems in the Luancheng County of the North China Plain. A dynanic system model coupled with social, economic and ecological subsystems of agriculture for the Luancheng County was constructed with a time step of one month. The model includes five main components, water resources, profitability, irrigation, crop yi...

Agricultural systems are situated within social and political environments that have tremendous influence on how they operate. If agricultural systems are to be sustainable, it is critical to understand how they are influenced by social and political factors. An expert panel approach was used to identify and rank the importance of social and political factors on agricultural systems in the US a...

Habitat conversion is the primary driver of biodiversity loss, yet little is known about how it is restructuring the tree of life by favoring some lineages over others. We combined a complete avian phylogeny with 12 years of Costa Rican bird surveys (118,127 detections across 487 species) sampled in three land uses: forest reserves, diversified agricultural systems, and intensive monocultures. ...

Priming is the cellular state in which the harmful effects of abiotic stress factors in plants are hindered by pre-exposure to a stimulus, thus resulting in greater survival. It is becoming increasingly evident that priming techniques (e.g., external application of natural or synthetic compounds in plants) can enhance the tolerance of crops to environmental stresses. Innovative systems biology ...

This paper explores the linkages between gender, local knowledge systems and agrobiodiversity for food security by using the case study of LinKS, a regional FAO project in Mozambique, Swaziland, Zimbabwe and Tanzania over a period of eight years and now concluded. The project aimed to raise awareness on how rural men and women use and manage agrobiodiversity, and to promote the importance of lo...

Integrated, interdisciplinary crop performance forecasting systems, linked with appropriate decision and discussion support tools, could substantially improve operational decision making in agricultural management. Recent developments in connecting numerical weather prediction models and general circulation models with quantitative crop growth models offer the potential for development of integ...
