Threats to sustainable food production are accelerating due climate change, population growth, depletion of natural capital, and global market instability. This causes significant risks farmers, consumers, financial policy institutions. Understanding agro-ecosystems, how varying management styles can impact their performance is critical future wellbeing. To better understand manage agricultural...

European farming is dealing with global questions as food safety, climate change and energy, while attempting to sustain competitiveness in world markets, higher standards of food production and responding to new demands for public goods and services. The energy requirements of food production are here a central issue. But a literature review on this topic, centered in the Mediterranean, reveal...

This study determined the situation of rural tourism and agro-tourism in Tehran Province as well as the expected economic impacts of agro-tourism development on it. In this research, we used documental research method and field research based on questionnaires and face-to-face interview. It was found out that despite different tourist attractions in rural areas of Tehran province, tourist arriv...

Highly hydrophobic organic chemicals (HOCs), like pyrethroids, adsorb strongly to eroded soil and suspended sediment. Therefore, total suspended solids (TSS) concentration in the water column of receiving waters is important for determining the proportion of chemical in the sediment-sorbed vs. the dissolved (bioavailable) state. However, most current regulatory exposure models, such as the Expo...

Within the context of climate change, water scarcity is the major constraint to the viability of many crops. Thus, it is necessary to develop strategies for sustainable water management, and introduce alternative crops to sustain the viability of agro-ecosystems. The main objective of this work was to assess the performance of hemp (Cannabis sativa L.) subjected to different plant densities and...

Identification of homogeneous invariant geographical units assumes considerable importance in the context of current attempts at developing environmental indices to monitor changes. Data on the edaphic and climatic parameters for the state of Gujarat--a predominantly arid to semi-arid province in western India--has been used to elaborate an approach that employs principal component analysis (PC...

This paper describes research using an agent-based artificial agro-ecosystem model to simulate the interaction between pest movements and trap crop physical design. The result of simulation shows that artificial agro-ecosystem model has a broad application prospect in the field of agro-ecosystem management.
