Aptitud de la tierra y análisis de sensitividad en la planificación del cultivo del manzano en el valle Mala, Perú

This study determined the suitable zones for planning apple growing in Mala’s valley, Peru, using analytical hierarchy process (AHP) in a geographic information system (GIS) environment. The suitability evaluation involved the analysis of nine criteria organized into four groups (soil, topography, hydro-climate and socioeconomic). Based on key informants assessments relative weights were assigned to each nine criteria using the AHP. A digital GIS database was developed with all the thematic maps. The criteria were reclassified before combination, according to a four-class system for suitability. Then, a summarized process was done by applying the weights to each criterion, followed by a summation of the results to yield a suitability map using GIS. Layer and weight sensitivity methods combined with Kappa analysis were carried out in order to prove the robustness of the suitability model. The results revealed that about 12.57 % (9953 ha) of agricultural area are suitable for apple cultivation and out of which 3.98 % and 3.37 % are highly and moderately suitable, respectively. If farmers in the valley considered growing apple crops in the 3149 ha (highly suitable), the gross profit would have substantial increase. Therefore, the final map can become a useful tool of territorial governance and policy in order to assist in the agricultural expansion process of Mala’s valley.Se determinaron las zonas aptas para la planificación del cultivo del manzano en el valle Mala, en Perú, mediante el uso del proceso analítico jerárquico (AHP) en un sistema de información geográfica (SIG).

A GIS-based multi-criteria analysis on cropland suitability in Bornuur Soum, Mongolia

Agriculture is one of the most critical sectors of the Mongolian economy. In Mongolia, land degradation is increasing in the cropland region, especially in a cultivated area. The country has challenges to identify new croplands with sufficient capacity for cultivation, especially for local decision-makers. GIS applications tremendously help science in making land assessments. This study was carried out in Bornuur soum, Mongolia. The goal of this study to estimate that best suitable area for supporting crop production in Bornuur soum, using a GIS-based multi-criteria analysis (MCA) and remote sensing. GIS-based multi-criteria analysis (MCA) has been widely used in land suitability analyses in many countries. In this research, the GIS-based spatial MCA among the Analytical Hierarchy Process (AHP) method has employed. The approach was enhanced for each criterion which as soil, topography and vegetation. The opinions of agronomist experts and a literature review helped in identifying criteria (soil data, topography, water and vegetation data) that are necessary to determine areas suitable for crops. The detailed cropland suitability maps indicate that 46.12 % is highly suitable for cropland, 34.68 % is moderate suitable, 13.64 % is marginal suitable and 5.56 % is not suitable. The MCA and AHP tools play an essential role in the multi-criteria analysis. Therefore, the results of these methods allow us to estimate an appropriate area for cultivation in Bornuur soum, Tuv province. The crop suitability method implies significant decisions on different levels and the result will be used for cropland management plan to make a decision. It is an integral role in agricultural management and land evaluation. Future research should further develop this method by including socio-economic (potential citizens for agriculture, current crop growth, water resource, etc.) and environmental variables (rainfall, vegetation types, permafrost distribution, etc.) to obtain specific results. However, it could be also be applied for a single crop type (mainly barley, wheat and potato) in Mongolia
