This paper attempts to point out some specific problems in irrigation in Thailand and tries to show where policy related to these problems needs to be reviewed. The first section of the paper provides a brief historical overview of irrigation development in Thailand. The second section discusses policy problems related to the end users of the irrigation water. The third section addresses policy issues related to the Royal Irrigation Department (RID) and its performance. The fourth section raises some major issues concerning second generation environmental problems within irrigation systems in the north and the northeast of Thailand. The fifth section touches briefly upon the questions of small-scale systems in the northeast. The final section offers some suggestions for future policy research and review related to the issues raised in the previous sections.
5 Johnson, S. H. III. 1977. The economics of precision land leveling: A case study from Pakistan. Agricultural Water Management, 1:319-331.
(Location: IWMI-India Call no: F 631.7.4 G730 JOH Record No: H0810)
This paper examines the effectiveness of a production technique, precision land leveling (PLL), to minimize the losses of water between the rivers and the plant root zone. It identifies the economic and physical benefits attributable to precision land leveling. While the work is specific to Pakistan, the implications are levant for other arid areas of the world where irrigation is practices. Two sets of fields were selected, one set that had been precision leveled and another set that had been leveled using traditional techniques. The economic analysis of precision land leveling, assuming a life of 10 years, proved to be positive but not above the two or three to one return that is usually required to persuade subsistent farmers to invest in a new technology. However, the precision land leveling acts as a catalyst and increases the efficiency of the other associated inputs. Hence, it is a more valuable investment than is indicated by simple economic analysis.

Drainage, groundwater withdrawals and altered irrigation practices are among the techniques for reducing waterlogging problems resulting from inefficient water use. However, these corrective measures are often not adopted since the private costs incurred by the individual operator quite often exceed the private benefits. Net social benefits are likely to be positive, so collective action may be appropriate. The overall objective of this paper is to develop an integrated approach combining both economic and physical considerations in order to evaluate possible collective alternative approaches to relieving waterlogging problems. Using survey data from the San Luis Valley, this paper presents a recursive linear programming model that includes both uncertainty and capital constraints. This model incorporates a weekly short-run water allocation model and a simplified water balance model of the groundwater to form a complete simulation model. The model was run using 20 years of historical climatological data to represent the long-run effects of policies which might be undertaken by the water users or by the Colorado State Engineer. Policy alternatives modeled include: Investment in canal lining, total conversion to sprinkler irrigation, various restrictions on groundwater pumpage, and a modified quota-market system. A comparison of the economic and physical results of these simulated alternatives is made and policy recommendations are suggested.

Using a computer model, alternative irrigation management systems are simulated for the Punjab, the largest state in Pakistan. Economic results indicate that canal closure in February to April, rather than December and January, would increase per hectare returns by US $15-35. Due to the limited capacity of the present canals, changing from a continuous flow to a demand system does not appear to be economically feasible. However, if present allocation can be supplemented by private wells operated on demand, higher economic returns and more flexibility would be possible.

Over half of the water delivered from the canal system to the watercourses managed by the farmers is not made available to the farmers' crops in Pakistan. Most of this water loss is due to loss of water through the banks of the watercourses. Lack of maintaining these banks and lack of cleaning the watercourse is a result of inadequate organization of the 10 to 150 farmers who use the watercourse, and a deficiency of knowledge concerning the amount of their water which is being lost. Various methods of watercourse improvement have been evaluated including concrete and masonry linings and simple earthen improvements of the ditches with concrete control structures, junctions, and turnouts. With the cost of labor low in Pakistan, the earthen improvements with concrete structures appear to be the best investment. Farm water management improvement programs have been implemented in most of the provinces which include this type of watercourse improvement, land leveling and advice to the farmers on how and when to irrigate his crops to optimize his production. The rate at which personnel can be trained to help the farmers implement these improved water management practices is limiting the rate of implementation.

Examples are drawn from the Indus Basin to explain why on-farm water management problems restrict the output of agricultural products in many LDCs. Data are presented to illustrate the low level of water management knowledge of both the farmers and the current extension agents. Examples of the level of corruption and its effect on the operating system are illustrated. Several requirements that must be met before a large-scale irrigation scheme will actually increase the welfare of LDC farmers are presented.

With a total land area the size of the state of Illinois and a population exceeding 90 million, Bangladesh has one of the highest man-land ratios in the world. Blessed with vast river systems but having such a flat topography that large-scale reservoir and gravity surface irrigation systems are not feasible, Bangladesh has been forced to turn to groundwater as a source for dry season irrigation water. Initial investments were in low-lift pumps but now the Government of Bangladesh (GOB) is encouraging investment in hand pumps, shallow tubewells and deep tubewells as sources for additional water for irrigation. However, to date utilization rates have been far below those predicted by national planners. The purpose of this paper is to analyze the economics of alternative groundwater extraction devices in Bangladesh and to use their results to explain present low utilization rates. Using recent data, the analysis examines economic, social and technical characteristics of the alternative technologies and explains why shallow tubewells are to be encouraged over deep tubewells. Based on these results, suggestions for improving utilization rates are presented.

Examines the social, technical, and economic aspects of the massive investment in groundwater development in Pakistan and Bangladesh. Describes many of the physical parameters of the two systems which rely heavily on tube wells in order to focus on government policy concerning groundwater development and documents the economic and social impacts of the policies. The first two sections detail groundwater development and management in Pakistan and Bangladesh respectively. The final two sections discuss the social and economic impacts and the long-term implications of current policies. Lastly, the author draws some conclusions that may be used by the two countries, or other countries, as they expand groundwater development in the future.

The paper illustrates the relationship between investment in irrigation infrastructure and other agricultural policies and their impacts on rice production. Data based on rice production functions from the Central Plain of Thailand demonstrate that irrigation infrastructure investment is a necessary, but not sufficient, condition for expanded agricultural production. Other agricultural policies must complement the irrigation investment in order to obtain positive production increases. Disaggregated data which differentiate between wet and dry season rice production offer new insights into the process of agricultural development.

The paper presents preliminary results from the Asian Development Bank funded Study of Irrigation Management in Indonesia which is being collaboratively implemented by the International Irrigation Management Institute (IIMI) and the Directorate General of Water Resources Development (DGWRD). While the project is not focussed on soybeans per se, it does have a palawija component that, due to the research focus in Java, provides a significant amount of information on irrigated soybean production. The sites selected for the research are in "technical" irrigation systems that have extensive second and third season palawija cropping. The primary findings to date are that, even though these irrigation systems are technical systems with very little water scarcity, overall soybean yields are still relatively poor. One major cause of the low yields appears to be excessive water in the soil profile. Future research activities will focus on alternative bed shaping, in particular raised beds, in combination with irrigation scheduling to test the hypothesis that alternate bed shaping does have a significant impact on increasing yields.
