A Comparison of Approaches to Regional Land-Use Capability Analysis for Agricultural Land-Planning

چکیده
Smallholder agriculture is a major source of income and food for developing nations. With more frequent drought increasing scarcity arable land, accurate land-use planning tools are needed to allocate land resources support regional agricultural activity. To address this need, we created Land Capability Classification (LCC) system maps using data from two digital soil maps, which were compared with measurements 1305 field sites in the Dosso region Niger. Based on these, developed 250 m gridded LCC values across region. Across region, severely limited use because low available water-holding capacity (AWC) that limits dry season potential, especially without irrigation, requires irrigation where supplemental water available. If AWC limitation removed algorithm (i.e., simulating sufficient or much higher evenly distributed rainfall), dominant limitations become less severe spatially varied. Finally, used additional fertility samples illustrate value collecting contemporary dynamic properties critical crop production, including organic carbon, phosphorus nitrogen.

From the late twentieth century, human kind has found out that if he wants to obtain cost efficiently and continuous utilization of lands, it is better to execute this in a planned framework named management plan. Such idea is became as an introduction to monitor the land or utilization of lands. Monitoring lands means contribution of an optimized space for land utilization with realization o...

متن کاملPerformance comparison of land change modeling techniques for land use projection of arid watersheds
The change of land use/land cover has been known as an imperative force in environmental alteration, especially in arid and semi-arid areas. This research was mainly aimed to assess the validity of two major types of land change modeling techniques via a three dimensional approach in Birjand urban watershed located in an arid climatic region of Iran. Thus, a Markovian approach based on two suit...
