“…In that regard, the Mesozoic sedimentary aquifers present limited potential in terms of productivity and are not likely to support large scale irrigation or industrial development, but are vital for safe domestic water supply over wide areas. The Alluvial aquifers have the capacity to serve the highest priority of domestic water supply provision, but can also support supplementary irrigation during the dry season or dry spells in the monsoon [53]. Currently, less than 0.1% of irrigated areas use groundwater sources [54].…”

This study focuses on Laos, a landlocked nation located in SouthEast Asia with subtropical climate and highly seasonal rainfall distribution. Laos is one of the world's least developed countries, and currently witnesses an unprecedented level of development that is highly reliant on its natural resources, including groundwater. There is currently very limited data and no nationwide assessment of shallow (<30 m) groundwater resources to support sustainable management. This study provides a first step towards addressing this issue by (i) identifying the major aquifer units of the country; (ii) integrating localized data and regional maps into an assessment of the groundwater potential; and (iii) producing quantitative maps of key hydrogeological indicators. Eight aquifer units have been described and evaluated: (i) Basement aquifers, (ii) Volcanic aquifers, (iii) Schists, (iv) Paleozoic sedimentary, (v) Karsts, (vi) Limestones, (vii) Mesozoic sedimentary and (viii) Alluvial sediments. The Mesozoic sandstones and the Alluvial aquifers are the most extensive and productive hydrogeological systems in the country. The Volcanic and Karstic aquifers, although poorly known, might also have important potential. This assessment, along with the maps of quantitative aquifer indicators, provide a significant improvement in both spatial resolution and accuracy compared to previously available information. It will likely support improved management plans and the identification of areas with higher potential for groundwater development.

“…Moreover, the independent control this gives farmers over water management will further underscore the trend to farm diversification discussed below, given the higher returns to irrigating non-rice crops. Nevertheless, research in Laos indicates that, even where sourcing groundwater for cropping is demonstrated to be technically feasible, dry-season production may be limited by the increasing cost of labour and energy (Clément et al 2018).…”

White Gold: The Commercialisation of Rice Farming in the Lower Mekong Basin

View full text Add to dashboard Cite

The commercialisation of rice farming in the Lower Mekong Basin has been at the centre of that region’s remarkable journey out of poverty and food insecurity since the 1970s. A development strategy that centred on opening rice farming to productivity-enhancing investments had the double effect of increasing the incomes of large numbers of poor rural households while generating a marketable surplus to supply the rapidly growing urban population at low prices. The growth in export demand further added to the incomes of rice farmers in the more productive parts of the Basin. Thus, a development pathway emerged that was driven by political necessity to be broadly based and inclusive. However, the very success of this pathway has created new policy issues, requiring adjustments in the long-term emphasis on the intensification of smallholder rice production. The growth in production has led to a decline in prices while costs have been increasing. This has led to pressure from rice farmers for price support. Related policy issues include the persistence of smallholdings, the growing preference for more diversified farming systems, the role of the processing and exporting sectors, and the changing physical environment in the Basin. This chapter examines policies influencing access to resources (specifically, to land, water, and technology), the management of farm activities (whether specialised in production of high-quality rice or diversified into production of non-rice crops), and the appropriation of value (as determined by interventions in the marketing and pricing of paddy and rice).
