Production and area of chickpea are reducing every year in India due tocompetition with horticulture and other cash crops in irrigated areas. There is a greatscope for expanding chickpea production with or without limited irrigation in rainfedrice fallow lands (RRFL) in the states of Chhattisgarh and Madhya Pradesh. Nineteenchickpea genotypes were tested using participatory varietal selection (...

Exceedance of the US Environmental Protection Agency national ambient air quality standard for PM10 (particulate matter ≤10 μm in aerodynamic diameter) within the Columbia Plateau region of the Pacific Northwest US is largely caused by wind erosion of agricultural lands managed in a winter wheat–summer fallow rotation. Land management practices, therefore, are sought that will reduce erosion an...

nowadays because of various factors, including inappropriate land use, and indiscriminate exploitation of water resources, soil and vegetation, wide areas of the country were exposed to destruction of lands and desertification. therefore dealing with this situation requires a comprehensive land use program (water and land) and appropriate environment potency. the study area is patom district of...

Spatial pattern of trees can possibly indicate stand history, population dynamics, and species competition. This research was investigated in the Chahartagh forest reserve, Ardal region, chaharmehal and Bakhtiari Province, Central Zagros forest, and southwest Iranian state. In this study 53 hectare of the study area was selected and perfect inventory.  Information includes the position and kind...

East African forests have been largely converted to agriculture. The remaining forests hold many endangered species but are threatened by the heavy local demand for fuelwood. Here we evaluate fallow land in western Uganda as an alternate fuel source to diverse forests. We quantify the regeneration process on fallows, calculate tree biomass increases, and measure grass and woody herb biomass ove...

Land use change may influence many natural phenomena and ecological processes, including runoff, soil erosion, sedimentation and soil conditions. Decreasing of forest area in the North of Iran is one of the critical problems in recent years. The aims of this study are to detect land use changes between 1967 to 2002 using satellite images of Land Sat 7 ETM (2002), aerial photos and digital topog...

The JRC demonstrated the feasibility to assess and report in a harmonized manner, forest landscape pattern and fragmentation in Europe, on the basis of an easily reproducible set of indices. Results were used in the Forest EUROPE, UN ECE and FAO joint ministerial reporting process on the protection of forests in Europe where data on forest pattern do not exist from national forest inventories. ...

Information about how vegetation composition and structure vary quantitatively and spatially with physical environment, disturbance history, and land ownership is fundamental to regional conservation planning. However, current knowledge about patterns of vegetation variability across large regions that is spatially explicit (i.e., mapped) tends to be general and qualitative. We used spatial pre...

The long-term ecological response to recurrent deforestation associated with shifting cultivation remains poorly investigated, especially in the dry tropics. We present a study of phosphorus (P) dynamics in the southern Yucatán, highlighting the possibility of abrupt shifts in biogeochemical cycling resulting from positive feedbacks between vegetation and its limiting resources. After three cul...
