Recapitulating how genetic modification technology and its agro-food products aroused strong societal opposition in the European Union, this paper demonstrates how this opposition contributed to shape the European regulatory frame on GM crops. More specifically, it describes how this opposition contributed to a de facto moratorium on the commercialization of new GM crop events in the end of the...

The intensification of agricultural systems has caused a noticeable impact on agro-ecosystem services. Thus, the adoption more sustainable practices such as crop diversification and reduction external inputs represent an alternative strategy to minimize impacts intensive environment. This study aimed at evaluating effects rotation, conservation tillage, low-input strategies soil quality farming...

land vulnerable to desertification increased in the mediterranean basin since world war ii dueto several interacting factors including climate variations, land-use changes and growing human pressure. itwas hypothesized that the increase in the level of land vulnerability is not distributed homogeneously overtime and space while impacting preferentially landscapes surrounding large urban agglome...

feed resources availability at cheap and affordable prices for livestock consumption are major factors determining capability of livestock production to supply products for increasing urban and cities consumers in nigeria. to take advantages of the high demand in urban areas, livestock producers on extensive pastoralism are moving closer to cities and urban communities such as abuja the nigeria...

In recent years, elk have begun recolonizing areas east of the Rocky Mountains that are largely agro-forested ecosystems composed of privately owned land where management of elk is an increasing concern due to crop and forage depredation and interspecific disease transmission. We used a Geographic Information System, elk use locations (n = 5013), random locations (n = 25,065), discrete-choice m...

Wetlands are sensitive ecosystems that are increasingly subjected to threats from anthropogenic factors. In the last decades, coastal Mediterranean wetlands have been suffering considerable pressures from land use change, intensification of urban growth, increasing tourism infrastructure and intensification of agricultural practices. Remote sensing (RS) and Geographic Information Systems (GIS) ...

The Mediterranean area is one of the most significantly altered hotspots on Earth, since it has been intensively affected by human activity for millennia. As a result, only 4.7% of its primary vegetation remained unaltered and the landscape has been repeatedly transformed. In this paper, we aimed at detecting both the direction and the rate of landscape change focusing on the effects of human a...

Ecology may benefit from long term, large scale experiments on low intensity farming to test theoretical principles and convert them into practical lessons. One century of land conversion in the Argentine pampas, and its effect on critical ecological properties, were analysed and discussed. Land transformation has resulted in significant changes of land use, land cover, energy flow, nutrient dy...
