Nong Din Dam and Charoen Chai are located in Ubon Ratchathani state, within the sub-district of Nam Khun in Northeastern Thailand. They are 98 kilometres from Ubon City and 600 km nor'-east of Bangkok. Slightly more than half their populations are Catholic, while the remainder are Buddhists. Since Catholics are seen as foreigners in Thailand, a Catholic bulk is highly uncommon in Thailand. There is presently a church in the small towns, which sponsors the Nong Din Dam and Charoen Chai Rural Development Program, which attempts to help the villagers in assorted ways.
Ubon Ratchathani is both Thailand 's easternmost state and the Northeast 's most populated state, with a population transcending 1.5 million ( Cummings 554 ) . It covers 15 thousand square kilometres and has a great trade of cultivable land. Though Ubon is located on the Khorat Plateau, which is prone to utmost rhythms of waterlessness and implosion therapy, doing conditions similar to the `` African Savannah '' ( Fukui 19 ) , it is still an of import beginning of nutrient for the people of the Northeast.
The part 's importance as a major provider of nutrient does non insulate them for the tendencies of the national economic system. The recent downswing of the Thai economic system has affected the husbandmans even though they are located in a distant portion of the state. The devaluation of the Baht has made it progressively hard for husbandmans to turn a net income.
This is merely one of the many jobs the husbandmans of Nong Dim Dam and Charoen Chai face everyday. The husbandmans are covering with a broad assortment of other jobs including: inconsistent rainfall during the turning season, hapless dirt that lacks H2O and alimentary keeping capablenesss due to its flaxen composing, low H2O tabular array, and diminishing income due to utmost beads in the monetary value of rice ( Lutzky 21 ) . As there is deficient rain during the dry season, from November to April, they are presently limited to turning during the rainy season that extends from May to October. They grow gluey rice for personal ingestion, and sell manioc, maize and jute to gain money for necessities they can non bring forth themselves. This pattern earns the villagers an mean 10,000 Baht per twelvemonth, or $ 253 a twelvemonth.
There are a figure of different irrigation systems. The determination of which system to utilize will depend on a figure of factors including: the demands of the husbandmans, harvests grown, field size, capacity, H2O demands for specific harvests, the handiness of H2O, the terrain environing Nong Din Dam and Charoen Chai, and the budget and organisation of the villagers. The paper will measure these factors and the effects they will hold on both the feasibleness and creative activity of the chosen irrigation system.
To carry through our undertaking, our group will foremost place a beginning of H2O for the irrigation system. No irrigation system can be effectual with out an equal beginning of H2O. We are non likely to happen accessible land H2O, such as lakes streams or pools, due to the geographic location of the small town. Likewise, the small towns ' locations atop a tableland well decrease the chance of big organic structures of H2O of course happening within a sensible propinquity of the small towns. Alternate methods to roll up H2O may necessitate to be devised to supply H2O to the irrigation system.
Our group will besides measure the H2O demands for each type of harvest to find H2O demands for each field. With GIS function, we will build a elaborate map of field locations, lift and H2O demand. Possibly utilizing H2O shortage planning, our group will reexamine the critical volume of H2O required to do the system cost effectual, and find the feasibleness of an irrigation system.
If we determine an irrigation system is executable for the small towns of Nong Din Dam and Charoen Chai, our group will do recommendations for an irrigation system and develop a system for care and H2O distribution. It is our hope that, one time this irrigation system is implemented, it will be a major measure for the villagers in their pursuit to travel beyond subsistence agriculture.
Despite the recent displacement in the universe 's economic system towards industrialisation, agribusiness remains an economic basic in many states. Farmers constitute a important per centum of the population of many developing states, and of these, many are subsistence husbandmans, turning merely plenty to feed themselves and their households, with small or no excess. The dangers of farming at this degree are instantly evident. Give a hapless growth season, husbandmans may happen themselves unable feed their households without buying nutrient they can non afford, therefore traveling into debt. They operate at the subsistence degree because of scarceness of cultivable land, hapless dirt quality, or deficient entree to H2O and fertilisers.
Among the states in Southeast Asia, Thailand has really experienced an encouraging growing rate in agricultural end product, increasing about 2 % per twelvemonth during the 1950s, 5.4 % per twelvemonth from 1958 to 1973, and 3.9 % per twelvemonth from 1973 to 1984 ( Heenan 199 ) . This growing was mostly due to the addition in the sum of cultivable land, which increased from 10 million estates in 1850 to about 150 million estates in the 1980s ( Phongpaichit 3 ) . Despite this growing in national farm end product and agricultural land, most farms in the nor'-east received few benefits, due largely to hapless dirt quality and fickle rainfall.
The small towns of Nong Din Dam and Charoen Chai, located in Ubon Ratchathani state, approximately 98 kilometres from Ubon City in Northeast Thailand, rely on subsistence agriculture. The mean income in the small towns is a paltry 10,000 tical ( about U.S. $ 253 ) per twelvemonth. The `` Nong Din Dam and Charoen Chai Rural Development Program, '' established by the Mother of Peace Parish, has attempted to augment the villagers ' income by learning the adult females baking, run uping, handcraft, needlework, and through a `` savings mobilisation undertaking, '' leting villagers to gain involvement on their nest eggs, by assisting the villagers to raise cattles.
Though these attempts are well-meaning, they do non turn to the major jobs of hapless dirt quality and unpredictable rainfall, which are maintaining the harvest outputs at a subsistence degree. Without a dependable beginning of H2O, there is no manner that the husbandmans can progress to profitable agriculture position. The deficiency of cooperation and trust nowadays in the small towns, every bit good as their limited economic resources, has antecedently prevented an irrigation system from being developed.
This undertaking will measure the H2O demands for farming in Nong Din Dam and Charoen Chai, and develop a suited program for an irrigation system to run into those demands, therefore enabling the husbandmans to increase their harvest outputs. We will besides supply recommendations for a program for reasonably administering H2O from the system, every bit good as keeping it, both to be overseen by an organisation hand in glove run by the husbandmans. This irrigation system will supply the husbandmans with a dependable beginning of H2O, enabling them to increase their harvest outputs through a 2nd growth season, and therefore leting them to lift above the degree of subsistence agriculture.
Agribusiness has long been a basic of Thailand 's economic system. Specifically, much of the state must trust on subsistence agriculture, or turning merely plenty to feed one 's household. A deficiency of a dependable H2O beginning is forestalling the villagers in Nong Din Dam and Charoen Chai from traveling beyond the subsistence degree. This subdivision will first present information sing the two small towns, including plans that our patron has started. Since the big Catholic population of these two small towns may besides hold a significant impact on our undertaking, we present information on Catholicity in Thailand and, more specifically, how Catholics are perceived by other Thais.
Since we do hold such limited information on the two small towns, we must utilize information on the general country, Ubon Ratchathani, to extrapolate to Nong Din Dam and Charoen Chai. After appraising the state of affairs Ubon Ratchathani, we so travel on to the national agricultural economic system of Thailand, which has a important impact on the villagers ' lives. After diging into the broader national issue, we so concentrate on the agribusiness in Ubon Ratchathani, including turning season, common harvests, and jobs confronting the husbandmans.
Our undertaking addresses possibly the most critical job of a deficiency of a dependable H2O beginning through the execution of an irrigation system in the small towns. Since urging a system requires a thorough apprehension of assorted aspects of irrigation, we so present background on different types of irrigation systems, factors associating to the pick of such a system, and issues of farmer direction of the system. Finally, since the building and care of an irrigation system is such a big undertaking, an irrigation co-op may be appropriate and, to this terminal, we present some basic concerted rules. This information should supply a solid footing for doing a recommendation to the villagers of Nong Din Dam and Charoen Chai.
The Ubon Villages
The civilization and demographic make-up of the small towns we will be working with are really of import factors in determining this undertaking. The undermentioned subdivision will show background on Nong Din Dam and Charoen Chai, every bit good as information on how spiritual differences may impact our undertaking.
Nong Din Dam and Charoen Chai
The small towns of Nong Din Dam and Charoen Chai are located in the state of Ubon Ratchathani ( in the subdistrict of Nam Khun ) , about 98 kilometres from Ubon City. The bulk of villagers are subsistence husbandmans, concentrating largely on gluey rice, while turning a little sum of jute and manioc. Steeped in poorness, the mean per capita income in the two small towns is a paltry 10,000 tical ( $ 253 U.S. ) . The small towns make up the Mother of Peace Parish, and somewhat more than half the dwellers are Catholic.
The church has formed the `` Nong Din Dam and Charoen Chai Rural Development Program, '' which has implemented several plans to supplement the villagers ' agrarian income. In a savings mobilisation plan started by one of the sisters in the parish, husbandmans pool their income and let others to take loans from the pool, to be paid back with involvement. In add-on, the church has begun to learn the adult females of the small towns run uping, handcraft, and needlework, which produces goods to be sold at market for extra income. With the aid of the plan, many of the villagers are now besides raising cattles. Since these plans are run by the Catholic Church, it is ill-defined to what degree, if any, the Buddhists in the small town are involved.
The husbandmans in Nong Din Dam and Charoen Chai can be described as subsistence husbandmans, intending they turn merely plenty nutrient to feed themselves and their households. In old ages where there is a excess it is normally traded or sold for a net income. There are restricting factors that keep them at the subsistence degree including deficiency of engineering such as irrigation and tractors, and the hapless quality of the dirt which limits the types and outputs of their harvests ( Wikipedia ) .
We must earnestly see that we are covering with subsistence husbandmans when measuring any recommendation for alteration of traditional methods. There is a significant hazard associated with a bad twelvemonth. In the instance of a calamity such as a harvest failure or a natural catastrophe the husbandman will non be able to feed his or her household, and may hold to sell assets including land to make so ( Scott 2 ) . An irrigation system in Nong Din Dam and Charoen Chai would be an indispensable constituent to extenuation of these hazards and the first measure in a move off from subsistence agriculture.
Catholicity in Thailand
The ample Catholic population in Nong Din Dam and Charoen Chai is untypical of most Thai small towns. It is necessary to analyze the function of Catholic Church in Thailand, every bit good as the general attitude of Thais toward the Catholic religion to find the consequence this spiritual difference will hold on our undertaking.
Thailand 's population is preponderantly Buddhist, about 95 per centum. Of the staying five per centum, Muslims make up the largest minority ( Niphon ) . There are merely an estimated 250,000 Catholics in the state ( about 0.4 % of the entire population ) , which is little even compared to the other minorities. In Ubon Ratchathani state, there are 24,967 Catholics, doing up merely 0.32 % of the population, despite the presence of a Catholic Diocese ( Cheney ) .
Although the people of Thailand are by and large accepting, the Catholics in Thailand are still seen as aliens for several grounds. One of these is due to their obvious minority. Most of the Catholic parishioners in Thailand are non by and large native Thais. The bulk come to Thailand from neighbouring states, preponderantly Laos, which is a close neighbour to the Ubon part. Thai people besides see Catholicism as foreign because many Catholics came to Thailand from antecedently colonized states, adding to the stigma of Catholicism ( Niphon ) . Although these are general tendencies of the relationship between Catholics and Thais, the nature of the relationship between the Catholics and the Buddhists in Nong Din Dam and Charoen Chai is still ill-defined to us.
The small towns of concern in this undertaking are located in the state of Ubon Ratchathani. Situated along the boundary lines of Laos and Cambodia, and with a population transcending 1.5 million, Ubon Ratchathani is both Thailand 's easternmost state and the Northeast 's most populated state ( Cummings 554 ) . Covering 15 thousand square kilometres, much of which is cultivable land, the country of Ubon is an of import provider of nutrient for the Northeast 's big population ( Lutzky 15 ) . Associating Ubon Ratchathani to Bangkok, the Mittaphap Highway, or Friendship Highway, runs 629 kilometer. Any goods that flow out of Ubon travel along this main road or through Thailand 's complex rail system to Bangkok.
Figure 1. Map of Thailand ( Central Intelligence Agency )
Unlike most other parts of Thailand, the Khorat Plateau, upon which Ubon is located, rhythms through extremes of waterlessness and implosion therapy, bring forthing waterless conditions similar to the `` African Savannah '' ( Fukui 19 ) . This has badly hindered the agricultural development in the part.
Figure 2. Map of Ubon Ratchathani Province ( MSN Learning & A ; Research )
Agricultural Economy of Thailand
It is of import to understand that, while the husbandmans in Ubon Ratchathani are mostly isolated from the remainder of the state, they are still affected by the larger national economic system. Bordered by Myanmar, Malaysia, Laos, and Cambodia, the Kingdom of Thailand covers 514,000 square kilometres and consists of four distinguishable parts: the North, the Northeast, the Central, and the South, each with distinguishable demographics, clime, and geology. As of July 2003, Thailand had a population of 64 million ( est. ) , doing it one of the universe 's 20 most thickly settled states, despite its modest size ( Cardinal Intelligence Agency ) . In the decennary before 1995, Thailand enjoyed its greatest productiveness and growing. In the undermentioned old ages at that place was a terrible economic downswing taking to the devaluation of the Baht and a national recession. The downswing resulted from substructure jobs, banking jobs, deficiency of skilled labour, and mounting jobs with economic inequality. In response, the Thai authorities enacted strong steps to assist reconstruct the economic system to its old province ( Fryer 1 ) .
Despite industrialisation in recent old ages, Thailand remains a to a great extent agricultural state. However, while agribusiness histories for 40 % of Thailand 's work force ( Fryer 1 ) , it makes up merely 8 % of all exports ( US 2003 Economic Summary ) . Because of this disparity, nutrient excesss, which are by and large a rareness in developing states, are a common happening in Thailand. Thailand 's high proportion of land proprietors to non-land proprietors is besides uncommon in the underdeveloped universe. This low rate of occupancy, combined with Thailand 's by and large big farms ( by Asian criterions ) has led to a higher criterion of life in Thailand than in other developing states. For case, the authorities privatized many concerns that were once government-owned. In add-on, the banking and fiscal systems were restructured ( Fryer 1 ) .
The Thai small town economic system has existed for 100s of old ages and, like the national economic system, relies to a great extent on agribusiness, and is frequently referred to as an `` arm 's length economic system, '' which reflects the little graduated table of farming in Northeast Thailand. Most husbandmans in the part sell their goods to middle work forces, who are in bend sell to jobbers or other types of markets. This system implies an unfastened market where purchasers and Sellerss can exchange to whoever gives them the best monetary value, frequently in an informal auction format ( Warr 81 ) .
Agribusiness in Ubon Ratchathani
Understanding some rudimentss behind the agribusiness in northeast Thailand and some of the jobs blighting the husbandmans will be critical to the success of our undertaking. There are two distinguishable seasons, a rainy season that extends from May to October and a dry season from November to April, with a average one-year rainfall in the part of 1600 millimeter ( Lutzky 17 ) . Crops are planted around the 3rd hebdomad of July, and are harvested in November. The chief harvests in the small towns include rice, maize, jute, and manioc. The small towns grow two types of rice: gluey ( gluey ) and non-glutinous ( non-sticky ) rice. The gluey assortment is grown for personal ingestion, while non-sticky rice is chiefly produced for sale ( Lutzky 18 ) .
Chemical fertiliser is applied to over 90 % of the rice grown in the country, while manure is applied to approximately 85 % . Some husbandmans do utilize irrigation ; nevertheless, this is limited due to technological and fiscal limitations ( Lutzky 19 ) . Most northeasterly Thai husbandmans lack machinery, and by and large engage others with machinery to assist them with convulsing and milling, though they usually harvest by manus ( Lutzky 20 ) .
The husbandmans in the country environing Ubon are covering with a broad assortment of jobs:
hapless dirt that lacks H2O and alimentary keeping capablenesss due to its overly flaxen composing
low H2O tabular array
environmental harm due to improper fertiliser usage, and
insects and disease
inconsistent rainfall during the turning season
( Lutzky 21 )
An irrigation system has been identified as a agency for the husbandmans of Nom Ding Dam and Chaoren Chai to extenuate many of the hazards associated with subsistence agriculture, and possibly to travel beyond subsistence farming wholly. To successfully do recommendations for an irrigation system, nevertheless, the group must foremost derive a through apprehension of many different aspects of irrigation. The undermentioned subdivisions detail the different types of irrigation systems, factors that go into taking them, information sing H2O beginnings and cost, the construct of H2O shortage irrigation, and constructs for farmer-managed irrigation systems.
Types of Irrigation Systems
There are several available systems of irrigation to be considered for usage in Nong Din Dam and Charoen Chai. We must analyze these different types to organize a footing for our recommendation. The undermentioned subdivision examines three major types of irrigation systems: sprinkler irrigation, drip irrigation and gravitation irrigation.
This system, an illustration of which can be seen below, has gained popularity over the old ages due to it ease in operation and its usage of visible radiation and cheap aluminium piping. The chief elements of a sprinkler system are the beginning of H2O, the chief grapevine, the bomber chief grapevines, the sprinkler laterals, and the sprinklers. Gravity fed lines or a pumping system force H2O through the system and onto the Fieldss. The chief grapevine of this system brings H2O from the beginning to the Fieldss ; these pipes are by and large made of either PVC or aluminium. The bomber chief pipes branch off the chief pipe and present the H2O to the single Fieldss, frequently running along the boundaries of the Fieldss providing the H2O to the sprinkler laterals. The sprinkler laterals supply the H2O from the pipes to the existent sprinklers, which spray the irrigated H2O over the coveted country. As pumps are frequently expensive, there is important cost associated with the equipment used in this type of operation. Construction of this system is reasonably simple, nevertheless ( Finkel 193 ) .
Figure 3. Sprinkler Irrigation System ( CA Dept. of Water Resources )
Drip irrigation is similar to sprinkler irrigation in that pumps or gravitation deliver H2O to the Fieldss in the same manner. When the H2O reaches the Fieldss, nevertheless, it is non sprinkled over the harvests, but a system of porous pipes is used. The pipes rest on the land, as seen below, and supply H2O to the dirt at a slower rate than that of sprinklers. The porous pipes deliver H2O straight to the base of the workss, cut downing the losingss to evaporation, and therefore doing this system more efficient. The pumping equipment that may be necessary to travel the H2O in this system is besides expensive but, once more, building is non hard ( Finkel 247 ) .
Figure 4. Drip Irrigation System ( USDA )
Gravity irrigation is another major type of H2O bringing. This system besides uses a chief H2O beginning but uses gravitation instead so a pump to travel the H2O. Furrows or canals, similar to the 1 seen below, are frequently used as a manner of presenting H2O to the Fieldss, but husbandmans can utilize different types of piping as an option. This system is labour intensive because the furrows and canals need to be built and maintained, but is cheap due to the deficiency of pumping equipment. An added consideration with gravitation irrigation, nevertheless, is the topography of the land due, to its trust on gravitation. This system works best on degree or moderate inclines ( Finkel 349 ) .
Figure 5. Gravity Irrigation ( San Joaquin Geological Society )
Water Deficit Irrigation
Most irrigation systems assume a close infinite H2O beginning. When watering in semi-arid parts, this is non a feasible premise. A H2O shortage theoretical account recognizes a limited H2O supply and adjusts to run into those considerations. Water shortage irrigation, merely set, is under-watering a works to maximise H2O dispersion among a larger figure of workss ( Gorantiwar ) . Gorantiwar and Smout define the intent of under-irrigation as `` to distribute available H2O over a big country, thereby increasing the entire usage of H2O or energy per unit irrigated. '' Both energy and H2O usage will necessitate to be minimized for an irrigation system in Charoen Chai and Nong Din Dam, due to a deficiency of financess and the scarceness of H2O. Under-irrigating harvests will non give crops of a superior quality ; in fact, the harvested fruits will be little and developing. By tight direction of H2O, nevertheless, the procedure can increase the volume/mass of a crop by up to 40 % ( Gorantiwar ) .
Farmers can utilize a figure of H2O beginnings to obtain H2O for irrigation. These beginnings include the ocean, rivers, watercourses, springs, lakes, purchased H2O, Wellss, and rainfall ( Hackelman 1-7 ) . Unfortunately, due to the limited budgets of the husbandmans and the geographic location and terrain, the bulk of these beginnings will non be executable. We are non likely to happen accessible land H2O, such as lakes, watercourses or pools, due to the geographic location of the small town. Farmers could buy H2O, but its cost is prohibitory. There is a important sum of precipitation. Eighty-eight per centum of the mean rainfall, nevertheless, occurs between May and October ( Lutzky 17 ) . To use this beginning of H2O we would hold to invent a system to roll up and hive away excess rain during the rainy season for usage during the remainder of the twelvemonth.
To measure and compare the costs associated with each irrigation system we must take both the initial investing and the long term costs into consideration. The initial investing is comparatively easy to measure. All outgo associated with the purchase of constituents, stuffs, and the building of the system make up the initial investing. Long-run costs can be broken up in to two groupings, `` fixed '' and `` variable '' costs ( Roth 103 ) . Fixed costs accumulate irrespective of whether or non the system is in usage. Depreciation, revenue enhancements and insurance are illustrations of these. They are besides known as `` the cost of having a system '' ( Roth 104 ) . `` Variable or operating '' costs are disbursals that occur due to the usage of the system, and include repairs/maintenance, fuel, oil, and labour ( Roth 105 ) .
Factors Affecting the Choice of an Irrigation System
When be aftering the execution of an irrigation system it is necessary to see many factors. Several of these include the H2O beginning, topography, clime, dirt types and harvests.
Several factors affect the effectivity of a H2O beginning, including:
acceptable flow rate
distance from Fieldss ( affects the demand for a pump ) , and
H2O quality ( presence of chemical deposits ) .
The topography of the part ( the incline of the terrain ) can be a confining factor in taking an irrigation system. Farmers can utilize all systems on minimum to chair inclines, but can merely utilize drip irrigation on steep inclines. The uniformity of the incline can impact the flow of H2O in all types of systems but is by and large non a job for the three prevailing irrigation systems discussed before ( Finkel 37 ) .
We must besides see the clime of the irrigated part when measuring the pick of an irrigation system. Sprinkler systems are non suited for blowy conditions, as air current can greatly interrupt the uniformity of the system and increase vaporization well. The temperature and humidness greatly affect the efficiency of a sprinkler system by helping vaporization. In the instance of high temperatures and low humidness, it is best to utilize trickle or gravitation irrigation ( Finkel 39 ) .
Dirt in the irrigated part is besides an of import consideration, as it can impact the lacrimation method. Soils with high wet capacity require H2O less frequently but necessitate more H2O each person lacrimation. Dirts with low wet capacity need H2O more often and do increased losingss due to runoff ( Finkel 39 ) .
The type of harvest being grown besides has important importance when sing an irrigation system. All types of irrigation are suited for row harvests. Gravity irrigation is best for closely separated harvests and groves ( Finkel 42 ) .
Planing for Farmer Control and Maintenance
Harmonizing to Yoder and Thurston, when planing an irrigation system to be run and maintained by husbandmans, there are five chief elements of a successful design procedure. The design procedure should: `` 1 ) : be policy-driven, 2 ) be field-based, 3 ) have farmer engagement, 4 ) include processs for larning from experience, and 5 ) integrate local logic, cognition, and experience '' ( Yoder 10 ) .
Any successful irrigation design undertaking must province clear policies that should back up husbandman direction and engagement. Though these policies must be clear, they must besides be flexible and able to accommodate to the husbandmans ' demands. This frequently causes jobs when authorities organisations are involved, as their budgeting regulations are frequently really rigorous, and can do important holds. Government policy should besides back up farmer ownership of H2O supplies and the irrigation substructure ( Yoder 10 ) .
To decently ease the design of a system, applied scientists of the system must pass important clip in the field. This is indispensable to guarantee the proper sum of husbandman engagement in the design. Engineers in the field can really see the physical location where their system will be implemented, every bit good as interact with the husbandmans to integrate suggestions. Though elaborate designs are frequently hard to do in the field, many irrigation undertakings do non necessitate such item. These frequently must be adjusted during the concluding building stage anyways, and really are non required for all but the most complex systems ( Yoder 10-11 ) .
If the system is to be owned and operated by husbandmans, their engagement in the full design procedure is important to the success of the undertaking. Engineers must show a positive attitude toward and keep healthy relationships with the husbandmans. In add-on, it is critical that they meet with husbandmans frequently to maintain them informed of the advancement of the undertaking and any holds or alterations. They must stay informed of the costs of the undertaking and understand what they will be responsible for. In big undertakings such as irrigation building, it is common for husbandmans to organize husbandman groups, either officially or informally, to promote engagement in the design procedure ( Yoder 11 ) .
While it is evident that the applied scientists planing a system must supply preparation to the husbandmans responsible for pull offing it, husbandmans besides play a cardinal function in supplying information to the applied scientists. The husbandmans have the advantage of holding observed the Fieldss for many old old ages, while the applied scientists can merely detect them for a short clip. To derive as thorough an apprehension as possible of the Fieldss, applied scientists must see the field on multiple occasions, and pass on openly with the husbandmans to place issues they may meet ( Yoder 12 ) .
An facet of the design procedure that applied scientists frequently overlook is to place the aims of the husbandmans. The applied scientists ' standards for a good design may non ever fit up with the husbandmans ' , and this must be determined at an early phase. In add-on, applied scientists should set up a simple and effectual forum to pass on design thoughts to the husbandmans. Yoder and Thurston suggest conveying husbandmans onsite and taging off countries with bets and strings, alternatively of discoursing abstract design thoughts in a big meeting. Another effectual agencies of pass oning design programs is for applied scientists to construct 3-dimensional theoretical accounts of the proposed constructions. If executable, it is besides recommended to take the husbandmans off-site to locations where similar systems have been implemented. This accomplishes two of import undertakings. It allows the husbandmans to really see a system in operation. More significantly, though, they can discourse the direction issues of the system with other husbandmans ( Yoder 12 ) .
Due to the significant cost of set abouting an irrigation undertaking, it will be necessary for the small towns to move hand in glove by pooling resources and sharing the duties for care of the system. Harmonizing to the International Co-operative Alliance ( ICA ) , a co-op is `` an independent association of individuals united voluntarily to run into their common economic, societal and cultural demands and aspirations through a jointly-owned and democratically-controlled endeavor '' ( p. 2 ) . The organisation besides identified seven rules which embody the spirit of co-ops. Any organisation, whether formal or informal, that is formed in relation to this irrigation undertaking, should adhere to these rules:
Membership in a co-op should be voluntary and unfastened to anybody willing to utilize its services.
Cooperatives must be democratically controlled by their members, and those functioning every bit elected representatives of the co-op are accountable to its members.
Members must make concern with the co-op in order for it to be successful, and may be rewarded in assorted signifiers for the sum of such concern.
Cooperatives must stay independent, and any understandings they enter into must retain that liberty.
Cooperatives should supply instruction and preparation to members, representatives, and employees.
Cooperation among co-ops is encouraged to function the concerted motion.
The concluding rule reads: `` Co-operatives work for the sustainable development of their communities through policies approved by their members '' ( International Co-operative Alliance 2-3 ) .
By adhering to these rules in the formation of a co-op for direction of the irrigation system, we will guarantee equity and equity to all who choose to take part.
This undertaking will measure the H2O demands for farming in Nong Din Dam and Charoen Chai, and develop a suited program for an irrigation system to run into those demands, therefore enabling the husbandmans to increase their harvest outputs.
The undertaking will take topographic point between January 9, 2004, and March 5, 2004, though we expect that the concluding building of our recommended irrigation system will take well longer. It is of import to concentrate the undertaking to a specific location and therefore, we will include merely the Fieldss in the small towns of Nong Din Dam and Charoen Chai.
The squad plans to carry through the end of the undertaking by transporting out the undermentioned stairss:
place the H2O demands of the villagers
identify beginnings of H2O for the irrigation system
design a program for a suited irrigation system
assess the impact of the terrain on the irrigation system
develop a concerted H2O direction program.
Identify Water Requirements
To find the feasibleness and complexness of the proposed irrigation system, we will foremost necessitate to place the H2O demands of the villagers. This will affect taking elaborate measurings of the Fieldss of the husbandmans who wish to take part in the undertaking. We will necessitate to find the entire land country we will necessitate to water. In add-on to this, we will map out the harvests that are grown on each field, and the typical H2O demands for each harvest. The H2O demands for each harvest will be determined through mention beginnings and interviews with the villagers. With this combined information, we can find the entire sum of H2O required for harvests for the small town. We will so find the minimal rainfall the husbandmans can anticipate in a given twelvemonth, by looking at rainfall informations for the country, and besides from the husbandman 's cognition of annually rainfall. Subtracting this figure from the entire H2O demands of the villagers will give the sum of H2O the irrigation system must supply in a twelvemonth.
At this phase, if maps of the small towns are unavailable ( which we expect they wo n't be ) , we plan to map the Fieldss ourselves utilizing a GPS system along with field observations and measurings. While the GPS engineering is inexact, it is cheap and we expect that the mistake will non throw off our informations significantly. To bring forth these maps, we will utilize GIS mapping engineering with MapInfo package.
This phase of our undertaking will probably affect interviews with the husbandmans, which brings the communicating issue into drama. We are unsure how we will pass on with the villagers. At this point, we plan on the handiness of one of our patrons, either Sr. Lita or Ms. Cipriano, to construe for us.
As these informations are important for our undertaking to continue, it should be gathered every bit shortly as possible. We plan to hold it completed within the first two hebdomads of the undertaking period.
Identify Water Beginnings
Another measure in finding the feasibleness of the undertaking overall is placing beginnings of H2O for the irrigation system. We will turn up beginnings of H2O through interviews with the villagers and through analysis of maps of the country, if available.
Along with consideration of inactive H2O beginnings such as pools and reservoirs, we must besides see the sum of rainfall the country receives. It may be possible to integrate a rain aggregation system into the irrigation system, to salvage rain for later usage. Indeed, if there are no surface organic structures of H2O in the country, the system may necessitate to trust wholly on this rainfall aggregation system.
These informations are besides important to our undertaking, and should be collected at the same time with the informations from Objective # 1. This should besides be completed within the first two hebdomads of the undertaking period.
Develop a Plan for an Irrigation System
After roll uping the antecedently mentioned informations, we will be in a place to analyse this information and utilize it to urge a suited irrigation method to run into the demands of the husbandmans. In add-on to confer withing our ain information, it will be of import to garner sentiments and position from the villagers at this phase. Since they will be responsible for keeping the system, it is of import that we take their input into consideration when doing our proposal.
Assess Terrain Impact
As par of developing a program for an irrigation system, we will measure the impact of the terrain on a possible irrigation system. This is necessary to find which types of irrigation systems, if any, would be appropriate, as comparative lift can hold a important impact on the public presentation of the system.
To carry through this, we will seek for lift maps of the country. If we are unable to turn up these, we will map the country ourselves, utilizing either a GPS system, an altimeter, or an oculus degree. This will be the concluding stage of information-gathering before the existent design procedure begins because it plays such an of import function in the design of the system. This information should be collected by the terminal of the 3rd hebdomad of the undertaking period.
Develop a Concerted Water Management Plan
Finally, after carefully analysing our informations and urging an irrigation system, we will urge a system for administering the H2O and keeping the system, utilizing recognized concerted rules. We will roll up informations from other small towns with community-managed irrigation systems to find common and acceptable methods for such direction. In add-on, we will interview husbandmans in the small towns to garner their positions and suggestions on this direction system.
Again, this presents us with a communicating issue. It will be imperative that we are able to pass on with husbandmans in other irrigation co-ops every bit good as those in Nong Din Dam and Charoen Chai. While we hope to trust on Sr. Lita and Ms. Cipriano to construe in the two small towns, we may necessitate to engage a third-party translator for communicating when we visit other irrigation co-ops. We plan for this work to be ongoing throught the term. We will interview the villagers within the first few hebdomads but the visits to other farms and adept interviews could take topographic point at anytime during the undertaking period.
