“…Additionally, GIAM (aggregated raster maps at 10km-1km-500m) [12] and the Ramsar sites database were integrated to synthesize thematic spatial layers for the global irrigated and rain-fed agricultural regions. Regional analysis looked into representation of Ramsar sites and PWHs in the bio-geographic [13] and agro-ecological regions/sub-regions [14] of India. The data details are listed in Appendix 1.…”

This paper highlights the global and the regional scale representation of wetlands ecosystems using geospatial tools and multiple data sets. At global scale, the Ramsar database is investigated for representation of the wetlands sites of international importance against the "global agricultural zones" derived from the thematic aggregation of Global Irrigated Area Map databases. The analysis of "Ramsar sites" under cultivation reflects the present trend in wetlands use for agriculture. The scenario is also compared with the historical pattern derived from Vavilov's food zones of 1926. Observed is an aggregate increase in cropped wetlands area from 25% (1926) to 43% (2006). The second component develops a regional partnership with Salim Ali Centre for Ornithology and Natural History in India. The partnership reviews the thematic national database of inland wetlands and "priority wetlands habitats" (PWH) in comparison with the bio-geographic and agro-ecological factors (regions/sub-regions) and by means of geographical information system (GIS) tools. We elaborate the strength of spatial tools to better understand the relationship between wetlands distribution and agricultural zones, both historically and at the present time. The disseminated message states, though from a technical perspective, the understanding of scale and resolution in combining information from diverse sources is essential; the effective implementation of spatial analysis requires a true cross-disciplinary approach. Complementing that, relevant policy support and appropriate institutional arrangements are fundamental to advance the management work required for unification of wetlands conservation with the existing challenges of food and livelihood security.

“…Cropping patterns are generally planned according to soil types, irrigation water availability, crop rotation, water allocation policies, economic and ecological benefits (Subramaniam 1983;White 2009). Changing cropping patterns requires the input of abundant data from a wide range of sources and scales.…”

Irrigation water availability is a main driver which determines cropping patterns for an irrigation area. Irrigation water availability will potentially reduce due to changes in climate and irrigation extraction limits. Cropping patterns should be adjusted to meet this challenge. This study presents a new approach for assessing future cropping patterns using GIS in combination with an Irrigation Water Availability Simulation model (IWAS) at irrigation area scale. The IWAS-GIS framework was developed for analysis of cropping pattern options based on the forecast of irrigation water availability in 2030 for the Murrumbidgee Irrigation Area (MIA) which is one of the most important irrigation areas in Australia. Six scenarios considering climatic conditions and the irrigation availabilities were input into the IWAS-GIS framework to simulate cropping pattern changes corresponding to predicted monthly irrigation water availability. Cropping patterns were designed by integration of soil type and irrigation water availability to improve irrigation sustainability. Simulations results indicate that the total irrigated areas will likely decrease with drier climate and less irrigation availability. Rice and pasture areas change significantly when climate and irrigation availability varies. Under the same climate condition, horticulture area increases when irrigation availability decrease. The percentage of lands which are unsuitable for cropping has reduced with the drying climate and shrinking irrigation availability. The IWAS-GIS is simple to implement and provides an easy way for assessing spatial cropping pattern changes based on irrigation water availability. This framework was developed to help irrigators plan cropping patterns corresponding to

“…Soil-Climatic Zonation provides the best basic matrix on which a soil classification system can be built (Mandal et al,1999). Subramaniam (1983) delineated 29 Agro-ecological Zones of India with 36 combinations of "Moisture Adequacy Index" (IMA), (AE/PETx100) and dominant soil groups of FAO-UNESCO Soil Map. Krishnan (1988) proposed a 40 fold soil-climatic Zones of the country.…”

The complexity of soil variability, the purpose and use of soil survey information, soil classification and mapping at different scales are discussed. The need for a simplified National Soil Classification System based soil mapping for farm level land use planning at village / watershed scale is illustrated and reiterated. The paradigm shift from Soil Mapping to Land resource mapping at village level by detailed soil survey and socio-economic survey is emphasised for embarking upon a National Mission Mode Project, which will help in the development of Soil productivity indices and Rating, Land Capability Classification system and a National Portal on soils of India making Agro-Technology transfer both seed centric and soil driven.
