Introduction
Nepal, known for its predominantly agrarian society, heavily relies on agriculture as the primary source of livelihood for a majority of its population. However, the country's irrigation infrastructure has been a persistent challenge, leading to limited access to reliable water sources for crop cultivation. With only 30% of arable land currently benefiting from irrigation, farmers face significant constraints in achieving optimal crop yields and sustainable income levels.
Recognizing the urgent need to address these issues, there has been a growing interest in recent years to improve irrigation infrastructure in Nepal. The government, in collaboration with international organizations, has undertaken various irrigation projects, such as the Irrigation System Project (ISP) and the Medium Irrigation Project (MIP), to enhance the irrigation network and increase agricultural productivity.
One noteworthy initiative among these projects is the Shesnarayan Dakshinkali Irrigation SubProject. Its primary objective is to improve irrigation infrastructure in the Shesnarayan Dakshinkali area, situated within the picturesque Kathmandu Valley. This sub-project aims to provide efficient irrigation facilities to approximately 32 hectares of agricultural land, with the ultimate goal of improving the livelihoods of farmers in the region.
Despite the promising nature of such endeavours, the impacts of these irrigation projects on the local community and environment are not yet well understood. It is crucial to conduct a comprehensive impact study to assess the effects of the Shesnarayan Dakshinkali Irrigation SubProject, encompassing various dimensions and aspects.
This impact study seeks to evaluate the multifaceted consequences of the project, encompassing changes in crop yields, crop diversity, and income levels for farmers. By examining these indicators, researchers can gauge the direct benefits of the sub-project in terms of enhanced agricultural productivity and improved economic well-being for the local farming community.
Methodology
Research Design
This research evaluates the impact of the Sheshnarayan Dakshinkali Irrigation Sub Project on the local community and environment, focusing on changes in crop yields, income levels, water availability and quality, sustainability, maintenance, and community participation. It provides valuable insights and recommendations for future irrigation projects in Nepal, using a mixed methods approach of surveys, interviews, and focus groups to gain a comprehensive understanding of the project's outcomes.
Study Area
The Sheshnarayan Dakshinkali Irrigation Sub Project is located at Dakshinkali Municipality-5 which is around 14.5 km away from Balkhu. The project location is at an altitude of around 1500 m. The latitude and Longitude of the project area are 27°36'59.18" and 85°15'50.57"E.
Methods of Data Collection
1. Primary Data Collection: It involves a household survey with structured questionnaires administered to project beneficiaries. The survey covered irrigation, agriculture, water management, and other relevant aspects. Focus Group Discussions (FGDs) were conducted to gather in-depth insights on the research topic. Key Informant Interviews (KIIs) were conducted with relevant personnel to supplement FGD findings. Secondary data were collected from reports and documents.
2. Secondary Data Collection: It includes reports, documents, and articles, to complement the primary data. This secondary data encompassed feasibility and baseline survey reports, design reports, environment study reports, monitoring reports, budget and expenditure documents, and information from the Agriculture Knowledge Centre and Water Resource and Irrigation Development Division. The integration of secondary data enriched the research methodology and analysis.
Data Processing & Analysis
Data analysis was conducted using MS Excel, employing both qualitative and quantitative techniques. After data collection, calculations relevant to the analysis were performed to derive meaningful insights from the data.
Results and Discussion
1. General Overview of Irrigation System:
The Sheshnarayan Dakshinkali Irrigation Sub Project is one such initiative that aims to improve the irrigation infrastructure in Nepal. The farmers in the sub-project area used to convey water from the intake near the Sheshnarayan temple through earthen channels in the past during the monsoon season before the implementation of the project. The water was not adequate to irrigate all farmer's fields, especially during the winter season. After the implementation of the project, the farmers in the project area formed a WUA for the operation and maintenance of canals. The proposed work is the rehabilitation of the existing irrigation system.
2. Land Holding Pattern:
Most of the farmers in the project area are owners of land. However, some farmers have taken land on lease and are currently running farms. Even though the land holding pattern is not uniform farmers hold around 4-5 ropani of land including leased land.
3. Major Occupation
The majority around 51% of the respondents belong to the agriculture sector followed by service, business and others.
4. Income and Expenditure:
In the project area, agriculture is the primary occupation for the respondents. However, most of them stated that they have not been able to generate significant income from agriculture, as the crop yield is primarily sufficient for family consumption. Only a few farmers with larger farms can generate some savings from agriculture. The main sources of income from agriculture include vegetables, wheat, and paddy. A small number of respondents send their crops to the market, earning approximately NRS 25,000 per month. Other sources of income for the respondents include labour, electrician work, services, and business, contributing to a monthly income of around NRS 30,000. Surprisingly, only a few farmers in the project area are involved in livestock farming, resulting in minimal income generation from this sector.
5. Change in Cropping Intensity:
The project intervention aimed to increase the productivity of crops and crop intensity in the command area by rehabilitating existing irrigation facilities. So after the intervention cropping intensities increased to 231%. From the figure we can conclude that cropping intensities have increased to 231% from 169%. The table below shows a comparison of crop intensities during the different seasons before and after the project interventions in the respondent's land.
6. Change in Cropping Pattern:
After the implementation of the project, the cropping pattern of farmers in the project area changes hugely as compared to the old pattern. Most of the farmers used to grow paddy during the monsoon season and maize during the winter season. But after the implementation project, most of the respondents told during the field survey that they have started growing high-yielding vegetables during winter and summer. Now farmers grow paddy and vegetables during summer while wheat, potato and vegetables during the winter.
7. Agricultural Productivity
Overall, the productivity of agricultural products increased after the implementation of SDISP which is due to sufficient irrigation.

8. Project Impact:
Several factors, including poverty reduction, food sufficiency, higher income and spending, decreased workload for women, gender equality, and migration, were used to assess the irrigation system's impact in the command area.
(i) Economic Sustainability: The project's implementation has had a significant impact on raising the standard of living for the underprivileged. One of the biggest effects following the project's implementation in the command area is a decrease in poverty.
(ii) Employment: Farmers have begun selling their goods on the market as a result of the growth in agricultural productivity on irrigated land. Farmers who previously relied on seasonal and off-seasonal veggies for their living now have revenue. As a result, one of the key industries in this command area is the production of out-of-season vegetables. There is a visible increase in employment opportunities for farmers due to the provision of irrigation.
(iii). Food Sufficiency: Overall, most of the respondents told that the cultivated food items are just sufficient to fulfil their household demands. About 10% of respondents responded that the food is not sufficient for a whole year and they need to buy food products from the market.
(iv) Women’s Drudgery: Since women perform most agricultural labour, it goes without saying that the lack of water in agricultural fields adds to the burdens they already bear. This irrigation project's greatest benefit to women has been the reduction of their fieldwork workload and hardship.
(v) Time-Saving Utilization: To transfer water from the source into their irrigation canal, farmers used to devote important time. They also need to spend more time distributing water to their farms. The farmers had to wait for their turn because the water flow was limited. Farmers who steal water are dishonest, therefore disagreements are frequent. Peasants greatly increased their time for animal husbandry after the project participated in the project region. Similar to this, the civilization built an alluring social harmony that decreased water conflicts.
Conclusion and Recommendations
A) Conclusions: In conclusion, the study on the impact of the SDISP irrigation canal has provided significant insight into the positive effects that the efficient operation of an irrigation canal can have on a community. The successful operation of the canal has improved agricultural productivity, increased crop yield, and promoted economic growth in the surrounding areas. The efficient water distribution system has ensured that the farmers have access to water when they need it, allowing them to increase their crop production and maximize their profits.
B) Recommendations: To ensure the successful implementation and long-term sustainability of the canal system, a series of important recommendations can be put forth. Firstly, addressing accessibility issues is of paramount importance to guarantee the equitable distribution of benefits to all farmers in the region. This may necessitate improvements in transportation infrastructure or the provision of alternative means of access for remote areas. Concurrently, measures must be implemented to minimize environmental impacts associated with the canal, such as soil salinization and the loss of wildlife habitat. Achieving this objective entails adopting and promoting sustainable farming practices while preserving and protecting natural ecosystems.
