Sorghum has great potential to be cultivated and developed commercially because it has wide adaptability, high productivity, is resistant to plant pests and is more resistant to marginal conditions. Land evaluation is useful as a basis for sector development in an area that is useful for reorganizing the existing land use to assist in making land use planning decisions. This study that was aimed to evaluate land suitability for sorghum was conducted descriptively using the survey method. The sampling method used was based on a land map unit with a free grid system. The land evaluation was carried out by matching and comparing land characteristics with land suitability class criteria to obtain land suitability classes for sorghum plants in Bilah Barat District, Labuhanbatu Regency. There were six soil sample points collected at a depth of 0-60 cm to determine the value of soil characteristics. The results showed that the cultivated sorghum in Bilah Barat District, Labuhanbatu Regency of 12,829 ha which has the actual land suitability class for sorghum is Nwa with the potential land suitability class is S2tcwa.

Cacao is a primary commodity in the Keerom Regency, but production has been decreasing in recent years. Cacao cultivation on unsuitable land and without cutting-edge technology would impede efforts to increase its productivity. The study aimed to evaluate land suitability for cacao in Keerom Regency, Papua, and to suggest site-specific technologies. The study was carried out in the Keerom Regency of Papua in 2015. Land suitability assessment was carried out by matching data on land characteristics (climate, slope, soil type, and soil fertility) with land use requirements for cacao cultivation. The data was analyzed using geographic information systems. The result showed that 78.077 ha (8.60%) of the studied area were highly suitable for cacao cultivation, 123.645 ha (13.63%) was moderately suitable, and 389.603 ha (42.94%) was marginally suitable. About 316.082 ha (34,83%) of the studied area was classified as not-suitable. The recommendation technology for increasing cacao yields were fertilization, pruning, shade management, and individual terraces. Cultivation on suitable land and the application of technological innovations are expected to increase cacao production in Keerom Regency, Papua. The findings of this study could be used as a reference for policymakers to establish cacao development in the future.

Land resources are natural resources that are very important for human survival because natural resources are needed in every life. Land evaluation is an estimate of suitability for a particular land use in order to optimize the existing land in an area. This study aims to assess the suitability class of rubber plantations in environmental conservation efforts in Giri Nanto Village, Seluma Regency. The study was conducted in 2015 with a free survey method, analyzed descriptively qualitatively and quantitatively through an analysis approach to environmental impact and mapped through analysis using Arc.Gis software 10.0, land map units, and rubber land suitability criteria with a map scale of 1: 85,000. The results showed that the total area of potential land in the Giri Village area would later be 1,185 ha. The distribution of potential land suitability classes for  rubber plants was mostly S2 land classes (quite suitable) covering 622.82 ha (8.9%), S3 class (marginal suit) covering 526.4 ha (7.5%), and land classes N (incompatible) covers 35.68 ha (0.5%) .The limiting factor for the potential S3 land suitability class (according to marginal) is 16-30% slope, and class N (not suitable), namely rough soil texture. Allowing closed land to slope> 40%, and the texture of coarse soil as a protected forest area are expected to function as an alternative to sustainable land conservation for environmental conservation.

Poverty Point

Even though the general configuration of the Poverty Point site has been known for over forty years, the entire site was mapped for the first time in 1999–2000. In this paper we examine how Poverty Point has been portrayed in the archaeological literature. Tracings of stereoscopic aerial photographs were used to construct previous maps of the site. Features that could not be traced because of tree cover were interpolated. Succeeding representations of the site show different features and emphasize the symmetrical form of the site, including the presence of ridges separated by aisles. The 1999–2000 map demonstrates that earlier images of the site overemphasize earthworm symmetry. Our data suggest that the northern aisle does not exist and may have been introduced into earlier maps in order to complete a hypothesized regular site plan. Images of a site like Poverty Point are powerful representations of a perceived reality. For example, existing maps of Poverty Point have been used to bolster claims that the site represents a "great town," with a large population and some kind of centralized leadership. Despite a considerable history of research at Poverty Point map data alone cannot and probably will never provide sufficient evidence to support or reject such a claim. While mapping alone cannot answer questions about the nature of site organization or social behavior, differences between existing images and the current topographic map underscore the need to view maps and pictures of Poverty Point as a means for generating testable hypotheses, rather than an end unto itself.

AbstractCoffee cultivation in Central America provides goods and services at local, national, and international levels. Climate change is likely to affect the magnitude and continuity of these benefits by reducing the land suitability for coffee cultivation. To quantify the impacts of climate change on land suitability, we use the Bayesian network model Agroecological Land Evaluation for Coffea arabica L. (ALECA) and estimate the land suitability for coffee production in 2000, 2050, and 2080 under three climate change scenarios based on relative concentration pathways (RCPs) 2.6, 4.5, and 8.5. Results indicate that even under the less severe climate scenarios, over half of the current coffee area in Central America will experience a decline in its land suitability for coffee production, from excellent or good to moderate and marginal, and that the change will not happen in the more distant future of 2080, but by 2050. Under RCP 8.5, most coffee areas become of marginal and moderate suitability. The findings show that the continuity of coffee cultivation in a large portion of coffee areas in Central America is under threat and that farmers and policy-makers should develop adaptation portfolios for their farms and regions in a timely manner.

Land evaluation for irrigation is the process of predicting land use potential on the basis of soil attributes. The Food and Agriculture Organization (FAO) framework for land suitability evaluation is the most commonly used and is based on the biophysical properties of lands. The FAO framework method for land suitability application Boolean approach that has been criticized by some researchers. Because the Boolean representations ignore the continuous nature of soil and uncertainties in measurement and also its inability for overcoming problems related to vagueness in definition and other uncertainties, fuzzy set methodologies have been proposed. In the present study, the qualitative land suitability evaluation for sprinkler irrigation using parametric-based FAO learning and fuzzy inference system was carried out in an area of 5175 ha in Northwest Iran. By overlaying the layers (soil texture, soil depth, lime, electric conductivity, drainage, and slope) and use of spatial data modeler in ArcGIS 9.3, land evaluation maps for sprinkler irrigation were provided for the area under study. Results showed that based on the parametric approach, 1598 ha of the study area were classified as highly suitable (S1 class) for sprinkler irrigation; the area of highly suitable lands in the parametric method was about five times the area of highly suitable lands obtained through the fuzzy method. In addition, the two methods were completely different in determining moderately suitable lands (S2). Accordingly, 787 ha in the area was moderately suitable using the parametric method, which was about two times that obtained through the fuzzy method. This showed the significant difference between two methods applied to evaluate the lands. Moreover, fuzzy approaches accommodate the continuous nature of some soil properties and produce more intuitive distributions of land suitability indexes.
