Perennial cellulosic feedstocks may have potential to reduce life-cycle greenhouse gas (GHG) emissions by offsetting fossil fuels. However, this potential depends on meeting a number of important criteria involving land cover change, including avoiding displacement of agricultural production, not reducing uncultivated natural lands that provide biodiversity habitat and other valued ecosystem se...

Mediterranean-type ecosystems constitute one of the rarest terrestrial biomes and yet they are extraordinarily biodiverse. Home to over 250 million people, the five regions where these ecosystems are found have climate and coastal conditions that make them highly desirable human habitats. The current conservation landscape does not reflect the mediterranean biome's rarity and its importance for...

1. introduction the phenomenon of land consolidation has been the concern of economists, geographers, soil scientists, anthropologists, and politician in the last decades. it has achieved little success for agricultural development in iran. most of iranian land consolidation schemes ignore to meet sustainability criteria as a critical phase in the planning process. therefore, they have caused m...

Agroecosystems have traditionally been considered incompatible with biological conservation goals, and often been excluded from spatial conservation prioritization strategies. The consequences for the representativeness of identified priority areas have been little explored. Here, we evaluate these for biodiversity and carbon storage representation when agricultural land areas are excluded from...

Experiences worldwide reveal that degraded lands restoration projects achieve little success or fail. Hence, understanding the underlying causes and accordingly, devising appropriate restoration mechanisms is crucial. In doing so, the ever-increasing aspiration and global commitments in degraded lands restoration could be realized. Here we explain that arbuscular mycorrhizal fungi (AMF) biotech...

Three soils in the Loess Plateau were selected to explore the potential of applying the decision support system for agrotechnology transfer (DSSAT) crop models in the areas and to test the CERES-Wheat model under DSSAT shell. The predicted maturity dates and grain yields were similar to the actual measured values. The manural loessial soil had the highest productivity. The loessial soil had the...

In 2002. there were 88,458 fires reported on federal lands. These fires burned 6,937,584 acres and 2,381 structures costing taxpayers $1.6 billion for fire suppression. On average, 4,215,089 acres of federal lands burn annually. Forecasting wildland fire risk (occurrence and size) is important to fire managers who desire to know the risks of severe events well in advance of their happening. In ...

Canada’s agriculturally important lands include lands that are currently used for agricultural purposes (e.g. croplands, rangeland, pastures) as well as those that show potential for future agricultural development (e.g. natural grasslands). However, because these lands generally cover large geographical extents, their assessment by conventional ground survey techniques are often time-consuming...

The selling of hunting leases by private landowners has been regulated by the Texas Parks and Wildlife Department (TPWD) since 1925. However, a comprehensive examination of leasing activity and wildlife management practices used by landowners who lease lands for hunting has never been conducted. This study had three objectives: (1) to develop procedures to regularly monitor trends and changes i...
