Development of Tube well Irrigation
Simply, the development of tube well irrigation means the growth of construction and agricultural area covered by tube wells. Table 1 provides a detailed temporal of net shown area and tube well irrigation pertaining to its various types of irrigation system in the period of 2006-07 to 2016-17. There was an increasing trend of the net cultivated area from the year of 2006-07 up to 2009-10. In 2010-11, this trend became downward due to the effect of drought, and the intensity of traditional tube well practices were also changed in and after this period.
<Table 1>
A continuous rising trend of net sown area was again found in 2011-12. The tube well irrigation system has fluctuated from 2007-10 which was 27.98 hectares. The highest area of Tube well irrigation was 59.51 thousand hectares in 2016-17. While the lowest was 27.98 thousand hectares in 2006-07, 2007-08 and 2008-09.
<Figure:2 Scatter plot shows the relation between tube well irrigated area and total irrigated area in Dakshin Dinajpur district (2006-2017).>
So, it is quite cleared that the figures pertaining tube well irrigation were not distributed in linear manner across the considered time period. The result shows that there has been seen a positive relation between tube well irrigated area and total irrigated area because the changes in tube well irrigated area affected overall irrigation system within the district.
<Figure:3 Scatter plot shows the relation between STW and HDTW in Dakshin Dinajpur district (2006-2017).>
In 2006-07, the tube well irrigated area was 15.00 thousand hectares and the total irrigated area was 35.49 thousand hectares respectively, which is currently raised to 20.93 and 59.51 thousand hectares respectively. But the relation between HDTW and STW is totally opposite to earlier relation. To be more precise, an increase in HDTW in a particular given time results in a decrease in STW, which specifies negative relation.
Present Scenario of Tube Well Irrigation
Tube well irrigation in Dakshin Dinajpur district plays an important role as there is not canal irrigation system. Some of the blocks namely Balurghat, Hili, Kumarganj, Gangaranpur, Harirampur, Banshihari are situated near the river bank of Atryee, Punarbhaba, and Tangon. Hence, there has been seen alluvial soil that is acidic in nature. Only laterite soil is found in Tapan block. Tube well irrigation has changed the cropping pattern and productivity and productivity in many parts of the country.
<Table-2>
Table 2 shows that Hili has the highest tube well irrigated area of 78%. in 2016-17 and this is the highest among all the blocks of South Dinajpur. The block-wise decreasing order of tube well irrigation is as follows Harirampur, Banshihari, Kushimandi, Balurghat, Gangarampur, Kumarganj, Tapan.
<Figure:4 Percentage of Area Under Tube Well Irrigation >
The sharp increase indicates the development of tube well irrigation is dominated by installation of STW, followed by MDTW, LDTW, and other important projects like West Bengal Accelerated Development project of Minor Irrigation, Rural development Infrastructure Fund in All blocks of South Dinajpur district.
Tube well Irrigation and Socio-economic statusof Farmers
The development of agriculture relies on irrigation facilities. Availability of irrigation facilities changes the cropping pattern as well as crop production (You et al., 2011). The impact of irrigation transforms the farm characteristics, structure of crop prices, production instability, labor income, and farm income inequality (Peter Timmer, 1988). The farm household has been divided into 3 categories to discuss the socio-economic condition of farmers. These are- According to the census of India, 2011-
- Marginal (<1 hectare)
- Small (1 to 2 hectares)
- Semi-medium (>2 hectares)
Family Size
Man power is necessary for commercial subsistence agriculture (Gurri & Moran, 2002). Prior to modern days, Large family was considered as an asset as more people could engage in the agricultural activities thus raising the family income. But at present, this thinking has been changed in agrarian society. Hence, the size of family indicates both social and economic status. Here, the table-3 shows the family size has been grouped into 3 categories, i.e., less than 4, 4 to 6, and more than 6. The total number of marginal farmers are 80 persons. 9 (11.25%) has family size less than 4,68 (85%) has 4 to 6 and only 3(3.75%) family has more than 6 persons in their respective family.
<Table-3>
Out of 55 small farmers 8 (14.54%) has family size less than 4, 45 (81.81%) has 4 to 6, and 2 (3.63%) family has more than 6 persons in their family. Again, in case of Semi-medium farmers, out of 25 farmers only 2(8%) has family size less than 4, 22 (88.88%) has 4 to 6 and 2 (4%) family has more than 6 persons in their respective family.
Educational Status
In our society, level of literacy indicates social status of an individual to some extent. According to the census of India 2011, a person who can write and read with understanding in any language, aged seven years or above, is called literate. The literacy rate provides higher socio-economic status in our society and also reduces growth of population. Table-4 shows the educational status of farmers.
<Table-4>
Among Marginal farmers, the highest proportion (45%) has done primary education, followed by upper primary (28.75%), higher secondary (7.5%), secondary (6.25%) and only a few (2.5%) have completed graduation level of education. Similarly, out of 55 in case of small farmer, 15 (27.23%) has completed primary level of education and others have completed Upper Primary (29.09%), Secondary (18.18%), Higher Secondary (9.09%), Graduation (10.91%). Again, the highest proportion (32%) of large farmers have completed Upper primary level of education. In Primary (12%) (%) Secondary (20%) Higher Secondary level (24%) and only Graduation (4%) of Semi-medium farmers have completed. In this table, it has been found that out of 160 samples, 13 persons are illiterate because of high-rate school drop, especially in girls and poverty. In agriculture, education is very important to know about the productivity and other associated aspects of agriculture (Francis et al., 2001).
Occupational Status
Generally occupational status is a common factor to measure socio-economic condition that indicates prestige, privilege, and even power in society (Ganzeboom et al., 1992). Agriculture is the main occupation of selected sampled farmers. In addition to agriculture, they engage in other activities such as business, service, etc.
Table-5 reveals the income-generating occupation pattern. Out of the total 80 Marginal farmers, the main category has been found of cultivation (70%), followed by Cultivation & Fishing (15%), Cultivation & Poultry Farming (8.5%), Cultivation & Business (5%), Cultivation and Service (1.25%). Among small farmers categories, the highest percentage has occupied by Cultivation (60%).
<Table-5>
Secondly, 7.27% of medium farmers involve in fishing with agriculture and only 5.45 % of them are engaged with cultivation and poultry farming. Nearly 20 percent do business along with cultivation. Few small farmers (9.09%) are engaged with both the agriculture and service sector.
Again, in semi-medium farmer, the highest percent (28%) involve in agriculture, followed by Cultivation & Fishing (16%), Cultivation & Poultry Farming (24%) Cultivation & Business (24%), Cultivation and Service (8%). So, it can be said that these farmers are relying on agriculture. Currently, the children of farmers are uninterested to do agriculture because of limited income from agriculture. While Marginal Farmers with families are migrating to the city.
House Status
People can easily guess a farmer’s economic situation by looking at house types. Hence, Housing condition is an essential indicator that reflects the farmer’s socio-economic condition. Table represented 4 types of houses.
<Table-6>
Kuccha houses have been seen among (30%) of Marginal farmers, (27.27%), small farmers, (24%) of semi-medium farmers. From the table, it is clear that a small portion of farmers lives in tiled houses i.e. (12%) of semi-medium farmers, (21.82%) of small farmers, (13.75%) of marginal farmers, and majority of farmers live in semi pucca house. The highest percentage of pucca houses (36%) has been found by semi-medium farmers, followed by small farmers (20%), small farmers (18.75%). From the table, it is concluded that there is a significant difference in house structure within the study area. The results indicate that a large portion of farmers live in pucca houses and even a few farmers have capability to make pucca houses but they like to stay in semi pucca houses.
Live-stock
Animal husbandry is an important asset of farmers. Most Animals are used for agriculture activities. Table-7 detail description of livestock in Dakshin Dinajpur district has been discussed. In Tapan Block (17.27%) had the maximum percentage of cattle followed by Balurghat (16.30%), Kushmandi (15.99%), Gangarampur (14.90%), Kumarganj (13.54%), Banshihari (8.62%), Harirampur (8.53%), Hili (4.84%). There is a negligible difference in cattle among the blocks. The cattle are important for the farmer because of it meets the needs of milk for children and manure for agriculture. Again, the highest percentage (30.71%) of buffalo has been found in Tapan block and the lowest percentage (0.96%) is found in Kushmandi block. But day by day the number of this animal are decreasing in nature in Dakshin Dinajpur district.
<Table-7>
Sheep takes 1st position in Tapan (33.28%) block after that Kumarganj(24.81%) occupies 2nd position among all blocks. Banshihari, Harirampur, Gangarampur, Balurghat, Hili block accounts for nearly 40% of sheep. Just only 3.10% of sheep have been seen in Kushmandi block. In Kushmandi block, only 3% of sheep have been seen. It is found that in poor irrigated areas, sheep rearing is common practice. The highest percentage of distribution of goats has been seen in Kushmandi block (21.17%), followed by Tapan(21.17%) Balurghat (15.28%), Gangarampur(12.65%), Kumarganj( 11.85%), Harirampur (9.47%), Banshihari (7.32%), Hili (5.08%). Aside from these, farmers are engaged with pig farming, poultry farming, and other domestic birds like duck, hen, pigeon. The chicken, eggs, and other animals are very important for farmers' income. So, the results reveal that livestock farming plays an important role as secondary source of income for the farmer.
Cost-Benefit Analysis of major Crops
Cost-benefit analysis is a systematic approach that provides the economic framework and is used to determine cost-effective and beneficial Strategies for achieving benefits (David. et.al.2013). CBA is important or irrigated crops like boro, maize, and other winter season crops. Farmer needs at least 30 days to apply water for producing boro crop. Here CBA has done on maize potato and boro crops analyze the influence of Tube well irrigation on farmer’s economy. Table-8 shows the cost-benefit analysis of tube well irrigation system in Dakshin Dinajpur district. Here 3 major non-monsoonal crops have been taken that reflect the economic condition of the farmer. The total cost of Boro rice, maize, and potato are 23200, 18480, and 32040 rupees respectively. The total output of the same crop are 34180, 35510, and 66450 respectively. In this study area, tube well is main source of irrigation. This irrigation dominated area with good soil quality and environment increase productivity for agriculture of any crops and influence the economy of the farmer.
