Precision farming aims to optimize field-level management by providing information on production rate, crop needs, nutrients, pest/disease control, environmental contamination, timing of field practices, soil organic matter and irrigation. Remote sensing and GIS have made huge impacts on agricultural industry by monitoring and managing agricultural lands. Using vegetation indices have been wide...

Agronomic studies represent a supplemental but inevitable element of the municipal urban plan, which must guarantee agricultural lands their ranking as a non-negotiable resource, thereby protecting its own maintenance for the irreversibility of its eventual transformation. Furthermore, in recent years in Italy, the exasperated conflict regarding extra-urban space, between building expansion and...

~ Riparian lands are among the most productive ecosystems on earth. They occupy only a small proportion of the landscape but frequently support a greater variety and abundance of animal life than adjacent habitats. ~ Important habitat components include vegetation (often taller, denser, more diverse, and more complex in riparian lands), food, standing water, shelter from predators, sites for ne...

Grassland bird species have experienced substantial declines in North America. These declines have been largely attributed to habitat loss and degradation, especially from agricultural practices and intensification (the habitat-availability hypothesis). A recent analysis of North American Breeding Bird Survey (BBS) "grassland breeding" bird trends reported the surprising conclusion that insecti...

Hyperspectral images (HSI) offer detailed spectral reflectance information about sensed objects through provision of on hundreds narrow bands. HSI have a leading role in broad range applications, such as forestry, agriculture, geology, and environmental sciences. The monitoring management agricultural lands is great importance for meeting the nutritional other needs rapidly continuously increas...

Land-use change to meet 21st-century demands for food, fuel, and fiber will depend on many interactive factors, including global policies limiting anthropogenic climate change and realized improvements in agricultural productivity. Climate-change mitigation policies will alter the decision-making environment for land management, and changes in agricultural productivity will influence cultivated...
