Case studies and successes of rainfed agriculture around the world
1. Drip irrigation system in America
In the United States, drip irrigation is considered one of the most advanced and effective irrigation methods in arid regions. It has increased water efficiency, increased crop yields, and preserved biodiversity in its surroundings. Key factors include scientific research, farmer education, and investment in modern irrigation infrastructure.
2. Development of rainfed agriculture in Australia
In dry regions of Australia, rainfed agriculture projects have proven successful. The use of advanced irrigation technologies, soil management principles, and the promotion of drought-tolerant agriculture have led to significant successes in increasing production and conserving water resources in these regions.
3. Successes of rainfed agriculture in Iran
- Pressurized irrigation system in Yazd province: One of the most successful dryland farming projects in Iran is the pressurized irrigation system in some areas of Yazd. This project, by utilizing modern irrigation technologies, has improved the quality and quantity of products and has helped reduce water consumption in agriculture.
- Planting salt-tolerant crops on the southern coast: On the southern coast of Iran, farmers are successfully cultivating crops that are resistant to soil and water salinity. Planting salt-tolerant plants such as pears and pomegranates plays an important role in the development of rainfed agriculture in these areas.
- Drip Irrigation Project in Hormozgan Province: In Hormozgan Province, drip irrigation projects have been introduced as an effective and sustainable system for farmers. This system increases water productivity and reduces water waste in these areas, allowing farmers to cope with water shortage conditions.
- Planting roses in dry areas: Planting roses as a drought-resistant crop has been successfully carried out in some dry areas of Iran. This crop has become a suitable option in rainfed areas due to its low water consumption and high economic value.
The head of the Agricultural Jihad Organization of Qazvin Province announced on 12/01/1402 that the area of rainfed crop cultivation in Qazvin Province had doubled in the production leap plan in rainfed fields:
Mohammad Hossein Ataei, head of the Agricultural Jihad Organization of Qazvin Province, added at the webinar on the production leap plan in drylands: “In the last crop year, given that this province had a 10 percent decrease in rainfall compared to the previous year, despite this decrease, due to the set of technical measures taken in the production leap plan, we have had an 8 percent increase in production.”
He stated: “In the current crop year, the area under cultivation in the production leap plan in drylands has doubled compared to last year, and this year, 120,000 hectares of the province’s dryland lands have been allocated to this plan, and we are trying to support this amount of area.”
Ataei noted: “By implementing the production leap plan, we will witness an increase in the production of dryland crops in the province and an increase in the income of dryland farmers.”
The head of the Qazvin Province Jihad Kavarzi Organization said: “The executive credit for the production leap plan in drylands is not suitable for the province, and it is necessary to provide funds for the production leap plan in proportion to the announced level of cultivation so that the production leap plan in drylands can be properly implemented in the province.”
The successful results of these projects demonstrate Iran’s capability in developing rainfed agriculture. By continuing research and transferring successful experiences to other parts of the country, continuous improvements in water management and sustainable agricultural development can be achieved.
Factors affecting the success of rainfed agricultural projects:
- Scientific research and innovation: These case studies demonstrate that scientific research and innovation are crucial in the field of rainfed agriculture. Adapting technology to local environmental conditions and innovating solutions facilitate success.
- Education and outreach: Improving farmers’ knowledge of rainfed agriculture is another key success factor. Training farmers on optimal use of water resources, irrigation technologies, and drought-tolerant planting improves the feasibility of projects.
- Investing in infrastructure: Direct investment in the creation of modern irrigation infrastructure, water diversions, and technologies related to dryland farming has helped accelerate and advance projects and increased their effectiveness.
Transfer of experiences: To transfer successful experiences to other places, communication networks between countries and international cooperation are effective. Exchange of knowledge and experiences between countries, establishment of joint associations and organizations, and use of international mechanisms for technology and knowledge transfer are among these solutions.
