#1. Surface Irrigation

This type of irrigation involves the direct application of water to the soil surface. It can be further classified into furrow irrigation, where water is distributed through small channels along the field, and border irrigation, where water is applied through larger borders or strips.

#2. Sprinkler Irrigation

Sprinkler irrigation utilizes overhead sprinklers to distribute water over the fields. It is suitable for different soil types and crops and can be particularly effective in areas with uneven terrain or limited water resources.

#3. Drip Irrigation

Drip irrigation involves the slow, targeted application of water directly to the plant’s root zone.

It minimizes water loss through evaporation or runoff and is highly efficient in water usage. Drip irrigation is often used for high-value crops and in areas with water scarcity.

#4. Subsurface Irrigation

Subsurface irrigation systems deliver water directly to the root zone of plants through buried pipes or tubes.

It reduces water loss and evaporation, minimizes weed growth, and prevents soil erosion.

This method is suitable for crops with shallow root systems and areas with high salinity or waterlogging issues.

#5. Sprinkler-Subsurface Irrigation Hybrid

This hybrid system combines sprinkler irrigation with subsurface irrigation techniques.

It involves a combination of above-ground sprinklers and buried pipes to deliver water both on the soil surface and directly to the root zone.

This system optimizes water usage and helps maintain a balanced moisture level in the soil.

#6. Rainwater Harvesting

The process of rainwater harvesting entails the collection and subsequent storage of rainwater for future utilization in irrigation activities.

It typically utilizes rooftop catchment systems, storage tanks, and filtration mechanisms to capture and store rainwater during the wet season, ensuring its availability during dry periods.

#7. Traditional or Manual Irrigation

In some areas, traditional or manual irrigation methods are still practiced, such as using buckets, basins, or bamboo pipes to transport and distribute water manually.

These methods are often employed in small-scale farming or in remote areas with limited infrastructure.

Sources of Water for Irrigation in The Philippines

In the Philippines, various sources of water are utilized for irrigation purposes to support agricultural activities.

Here are some of the primary sources of water for irrigation in the country:

#1. Rivers and Streams

Rivers and streams serve as significant sources of water for irrigation. Water is extracted from these water bodies using intake structures and is then distributed through canals or pipelines to the fields for irrigation.

Rivers such as the Cagayan River, Pampanga River, Agno River, and many others play a crucial role in supplying water for irrigation in their respective regions.

#2. Reservoirs and Dams

Reservoirs and dams are constructed to store water from rivers and streams during the wet season.

These structures help regulate the flow of water and provide a reliable supply for irrigation throughout the year.

Major reservoirs and dams in the Philippines, such as the Angat Dam, Magat Dam, Pantabangan Dam, and Ambuklao Dam, serve as important water sources for irrigation projects.

#3. Groundwater

Groundwater, accessed through wells and tubewells, is another vital source of water for irrigation in the Philippines.

Deep wells are drilled into aquifers, which are underground layers of water-bearing rock or soil.

Groundwater extraction is particularly crucial in areas where surface water sources may be limited or unreliable.

However, it is important to manage groundwater resources sustainably to prevent depletion and maintain long-term viability.

#4. Rainwater Harvesting

Rainwater harvesting is an important supplementary source of water for irrigation.

It involves collecting and storing rainwater during the wet season for later use in irrigation during drier periods.

Rainwater is typically captured from rooftops and channeled into storage tanks or reservoirs.

This method is especially useful for small-scale irrigation systems and areas with irregular rainfall patterns.

#5. Springs and Natural Wells

Springs and natural wells that emerge from the ground provide water for irrigation in certain regions of the Philippines.

These sources of water often have a consistent flow and can be tapped for agricultural purposes.

#6. Water Reuse and Recycling

In some cases, treated wastewater from urban areas or agricultural runoff is utilized for irrigation.

By treating and reusing water, the Philippines promotes sustainable water management practices and minimizes water waste.

Importance Of Irrigation Schemes in The Philippines

  1. Increased Agricultural Productivity: Irrigation schemes are of paramount importance in the Philippines as they significantly enhance agricultural productivity. By providing a reliable and sufficient water supply to crops, irrigation schemes support increased yields and contribute to food security.
  2. Water Management and Conservation: Irrigation schemes play a crucial role in managing and conserving water resources. They enable the efficient distribution and controlled application of water, minimizing wastage and ensuring optimal utilization of this vital resource.
  3. Diversification of Crops: Irrigation schemes facilitate the cultivation of a wide range of crops throughout the year. By providing a continuous water supply, farmers can diversify their agricultural activities and cultivate high-value crops, leading to economic growth and improved livelihoods.
  4. Mitigation of Climate Variability: Irrigation schemes help mitigate the impact of climate variability, such as irregular rainfall patterns and droughts. They provide a stable water supply to counteract water shortages during dry spells, allowing farmers to sustain agricultural production even in challenging weather conditions.
  5. Poverty Alleviation and Rural Development: Irrigation schemes contribute to poverty alleviation and rural development by creating employment opportunities in the agricultural sector. Access to irrigation improves farmers’ incomes, reduces rural-urban migration, and stimulates economic activities in rural areas.

Benefits of Irrigation Schemes in The Philippines

  1. Enhanced Crop Quality and Quantity: Irrigation schemes ensure consistent moisture levels in the soil, promoting better crop growth, development, and overall crop quality. With adequate water supply, farmers can increase the quantity and quality of their produce, leading to higher market value and profitability.
  2. Increased Crop Diversity: Irrigation schemes enable farmers to cultivate a diverse range of crops, including high-value cash crops and crops with different water requirements. This diversification enhances farmers’ income potential, reduces vulnerability to market fluctuations, and contributes to a more resilient agricultural sector.
  3. Extended Growing Seasons: By providing a stable water supply, irrigation schemes extend the growing seasons beyond natural rainfall patterns. This allows for multiple cropping cycles in a year, maximizing land utilization and optimizing agricultural productivity.
  4. Reduced Dependency on Rainfall: The use of irrigation schemes reduces reliance on erratic rainfall patterns, which can be unreliable and insufficient. Farmers are less susceptible to the impacts of droughts and other climate-related challenges, ensuring a more consistent and reliable agricultural production.
  5. Improved Water Use Efficiency: Irrigation schemes promote efficient water use through technologies like drip irrigation and sprinkler systems. These systems minimize water loss through evaporation and runoff, optimizing water usage and reducing the strain on water resources.
  6. Food Security and Self-Sufficiency: With increased agricultural productivity and diversified crop production, irrigation schemes contribute to food security and self-sufficiency. The availability of irrigation water ensures a steady supply of food, reduces dependence on imported goods, and strengthens the resilience of the national food system.
