“…The GIS technology was applied to generate spatial data as part of geospatial information based on the result of USLE calculation and land evaluation. In addition to spatial analysis purposes, GIS was also applied to facilitate, improvement, storing, displaying, future utilization, and updating data (Abdel Rahman et al, 2016;Andy et al, 2002;Eswaran et al, 1992;Goodchild et al, 1992;Tomlinson, 1968). Furthermore, the RS technology was also used in this study mainly to identify land cover, present land-use, and digital elevation model (DEM) that represent basic factors for conservation aspects including soil erosion prediction model.…”

The main problem faced by sloping lands in the humid tropic includes land degradation influencing natural ecosystem damage broadly. Land conversion and improper land-use have been widely recognized as the main cause of environmental damage since the demands for agricultural lands become greater than land resource available. The objective of this study was to determine the concept of appropriate land-use planning through environmentally sound spatial management in order to prevent land and environmental degradation. The sub-district of Antang Kalang was chosen as study area representing sloping lands in humid tropic that have a susceptibility to erosion. Conservation approach by the use of USLE erosion risk prediction model and land evaluation through land suitability classification was used in this study. The geographic information system (GIS) and remote sensing (RS) technology were applied to generate spatial basic information and to assist in spatial analysis. Two crops, upland rice, and rubber, representing food crop and estate p have been selected based on the local resource that has been existed since a long time ago. The result of spatial analysis shown that the arable land for agricultural practices covers 9,039 hectares (23.19%) while for non-arable land, it is allocated for forest preservation with total areas 29,934 hectares (76.81%). Land-use planning and land resources management involving conservation aspect and land suitability evaluation should be taken into account for farming practice at sloping lands areas since the value of soil loss potential appears as an indicator of erosion risk. Permanent cultivation system and the intercropping farming system is the option of recommended agricultural practice at sloping lands in the humid tropic that have a susceptibility to erosion.

“…Under these relatively dry climates they are Entisols, Inceptisols, Alfisols and Mollisols in Andhra Pradesh; Inceptisols and Alfisols in Karnataka; Inceptisols and Alfisols in Tamil Nadu; Entisols, Inceptisols and Alfisols in Bihar; Entisols and Alfisols in Orissa; Alfisols and Mollisols in Madhya Pradesh; Alfisols in West Bengal; and Alfisols in Puducherry (Table 1). Taxonomic diversity in RF soils of India thus suggests that soil diversity in the geographic tropics of India is as large as that observed in the temperate regions (Eswaran et al, 1992a;Sanchez, 1976;Sanchez and Logan, 1992). From this it follows that generalizations on the management of RF soils would be rather hazardous as they are unlikely to have wider applicability because of a large diversity in these soils as a result of their genesis leading to a wide range in physical, chemical and biological properties.…”

“…They cover one-fourth of the total geographical area of 329 millon ha and are found in the states/ union territories of Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, Madhya Pradesh, Gujarat, Maharashtra, Goa, Orissa, Bihar, West Bengal, Sikkim, Manipur, Nagaland, Mizoram, Meghalaya, Arunachal Pradesh, Assam, Tripura, Pondicherry and Andaman and Nicobar islands (Bhattacharyya et al, 2009;Sehgal, 1998). As the tropics comprise approximately 40% of the land surface of the earth, more than one-third of the soils of the world are tropical soils (Eswaran et al, 1992a). Global distribution and research on these soils indicate that some of the agricultural management practices developed in one part of the tropical world for enhancing crop productivity and maintaining soil health, for example, through C sequestration and other management interventions, might also be applicable to similar soils elsewhere.…”

Red ferruginous (RF) soils of tropical Indian environments belong to Entisols, Inceptisols, Alfisols, Mollisols and Ultisols soil orders. The occurrence of Ultisols alongside acidic Alfisols and Mollisols in both zeolitic and nonzeolitic parent materials in humid tropical (HT) climatic environments, indicates that the soil diversity in India is large. These soils are not confined to a single production system and generally maintain a positive organic carbon (OC) balance without adding significantly to greenhouse gas emissions. This review presents a synthesis of literature on the recent developments on the pedology of RF soils, including their physical, chemical, biological, mineralogical and micro-morphological properties, and their degradation status. It also addresses the changes in soil properties in semi-arid tropical (SAT) areas, created by climate shift during the Holocene. This knowledge contributed to our understanding as to how the parent material composition influences the formation of Alfisols, Mollisols and Ultisols in weathering environments of HT climate; and also as to how the relict Alfisols of SAT areas are polygenetic. The state-of-the-art information developed through the extensive work on such soils has helped establish an organic link between pedogenetic processes and bulk soil properties, and has provided an insight of many pedological and edaphological issues related to Alfisols, Mollisols and Ultisols mainly of HT climate. The synthesis has helped us to understand as to why the formation of Oxisols from Ultisols is an improbable genetic pathway in tropical environment of India and elsewhere in the world. There is a strong need to modify the mineralogy class of highly weathered RF soils. We hope this review will help to dispel some of the myths on the formation of tropical soils and their low fertility by putting in context their characteristics and capacity to be productive.

Soils act as a major sink and source of atmospheric C 0 2 and therefore have a huge role to play in the carbon capture and storage (CCS) activity. The soils capture and store both organic (through photosynthesis of plants and then top , soils as decomposed plant materials and roots) and inorganic carbon (through the for mation, of pedogenic calciunucarbonates). The sequestration of organic and inor ganic carbon in soils and its follow-up require basic information of CCS in the soils and their appropriate management techniques. The most prudent approach to esti mate the role of soils as source and sink for carbon should require information on the spatial distribution of soil type, soil carbon (soil organic carbon, SOC and soil inorganic carbon, SIC) and the bulk density (BD). To estimate the CCS of soils in spatial domains, we have used the agroclimatic zones (ACZs), bioclimatic systems (BCS) of India and the agro-ecosubregions (AESRs) maps as base maps. These three approaches of land area delineations have been used for various purposes at the national and regional-level planning. We have shown the utility of these maps for prioritizing areas for C sequestration in soils through a set of thematic maps on carbon stock. It will make a dataset for developmental programmes at regional as well as national levels, to address the role of soils in capturing and storing elevated atmospheric .C02 due to global climate change.
