WATER MANAGEMENT AND SUSTAINABLE AGRICULTURE IN INDONESIA
Presented in Special Seminar on Food Security , Focusing on Water Management on Sustainable Agriculture Niigata, Japan, 5 – 7 September 2013
Republic of Indonesia Ministry of Agriculture
Background •
Indonesia consists of about 17.508 island of which 6,000 are inhabited
•
The archipelago covers 8 million square km of the earth’s surface with total land area of about two million km2.
•
Indonesia’s population is estimated at about 248 million with growth rate of 1,4%.
•
Republic of Indonesia is divided into 34 provinces, 402 regencies and 92 cities.
•
There are about 5,886 main rivers in Indonesia and the run-off-river flow has already been used for irrigation. Exploitation of the river flows depends on the storage of river supplies during rains. 2
Con’t... • Indonesia has varied rainfall distribution from 800 – 4000 mm/year. The rainfall are mostly concentrated within 5 (five) months whereas the other 7 (seven) months faces dry season. • Indonesian straddles the Equator and has typical equatorial climate. The east monsoon from June to September ( dry weather) and east monsoon from December to March (rain) . • Average temperature throughout the year 20– 32°C • Indonesian product domestic bruto percapita GDP in 2011 is 846, 8 billion US$ and Per capita income 2,844 US Dollar. at the current prices • population working in agriculture, plantations, forestry and fisheries sector, in the position on February 2013 were 39.96 million. And the exchange rate of farmers (NTP) around 104.58 in the position on July 2013.
OUTLINE • Introduction • Infrastructur Irigation and Paddy Field • Food Security and Roadmap on rice Surplus Production • Climate Change Impact of Food System • Policy on Agriculture Water Management • Conclusion
INTODUCTION 1. Water is very essentially and vital for all living organisms, course are directly related to agricultural production as the economic base of the people in rural area. 2. As a country that located on the equator, Indonesia overflowing with rainfall more than enough, but due to lack of good water management, Indonesian State water deficit since the last decade, especially in a densely populated island. In Java, for example, the deficit reached about 52.809 billion cubic meters, while in Sulawesi reached 9,232 billion cubic meters ( PU, 2011). 3. Java populated more than 150 million of the 248 million Indonesian population ( data BKKBN, 2013) or 60% of the total population will immediately run into a water crisis. 4. 64 Watersheds (DAS) , with a total area of 2.7 million hectares are in a very critical condition.
Issues & Challenges 1. Population :Increasing population around 1.4% per year (248 mill). a) competition for land and water and pressure to spatial utilization, including farm land; b) increasing water demand ; and , c) increasing food demand; etc 2. Critical fragmented farmland ( java average 0.3 hectare/house hould ) 3. Watersheed/ environmental degradation: has been affec to dependable waterflow. The degradation of catchment area are impacting the river discharge in which 89% of the national irrigation (non-reservoir irrigation) are depend on it ) and often water conflicts 4. On farm Infrastructure irrigation : Poor condition of irrigation network, cause low of efficienci use of water by farmer/WUA
Con’t... 5. Land Conversion : Indonesia has set a target to be self sufficiency in staple foods, particularly rice (surplus 10 mill ton by 2014), but some of irrigated areas have been converted into non-agricultural utilization (sawah) such as plantation (oil palm or rubber in Sumatra and Cocoa in Sulawesi), Industry, housing around 41, 32%. 6. Climate change (CC) is altering traditional weather patterns, and impacts on : water availability, and CC has been affect to rice production due to increase of magnitude of rainfall variability are rendering a high frequency of both floods and droughts in Indonesia.
PADDY FIELDS IN INDONESIA Generally, Indonesia has approximately 9.45 million ha of paddy field (BPS,2010), which consist of :
a. Irrigated paddy field : 7,23 million Ha (76%). b. c. d. e.
Tidal lowland paddy field : 488.9 thousand Ha (5%), Lowland paddy field : 171.9 thousand Ha (2%), Ground water irrigation paddy field : 92 thousand Ha (1%), and Others, such as rain-fed paddy field, traditional paddy field, and un-irrigated agricultural field : 1.47 milion Ha (16%).

PRODUCTION AND NATIONAL ROAD MAP ON RICE SURPLUS PRODUCTION
THE PROJECTION FUTURE NEED OF THE RICE PRODUCTION AREA AND THE IRRIGATED PADDY FIELD AREA As a result of population growth (projected for 2010 – 2030), Indonesia has to provide approximately 79.35 million of GKG. Based on assumption below, the calculation, shows that Indonesia has to provide 2.0 million Ha (or similar to 500 thousand Ha every 5 years) of new irrigated paddy field in order to maintain national food security.
Assumptions The calculation of the projected needs of irrigated area 2009 - 2030 is conducted with the following assumptions: 1. Rice consumption rate per capita (A) is 139 kg/capita/year; 2. Rice supply (B) is 18% greater than the rice consumption; 3. Paddy to rice conversion index (C) is 63.2 %; 4. Productivity rate of paddy field (D) is assumed to be 4.62 ton/ha; 5. Cropping area to harvested area conversion index (E) is 101% 6. Croping Intensity of the average Paddy Field (F) is 142%; 7. Croping Intensity of irrigated paddy field (I) is 160%; 8. Irrigated paddy field conversion rate (G) is 1.8% per year; 9. The rice production of the irrigated paddy field (H) is 84.5% of national rice production.

EFFORT TO REDUCE THE IMPACTS CLIMATE CHANGE (RAN – API) Climate change adaptation program of action aims to ensure or secure the achievement of key development goals such as food security. The main strategy to achieve the objectives of national adaptation action plan for climate change, Food Security Sector through: (a) adjustment and the development of farming systems to climate change, (b) Development and implementation of adaptive technology to climatic stress, (c) Development and optimization of land resources, water and genetic. those strategies are realized through 7 Main Program (Cluster) : 1. Adjustment Cluster Food Production Systems. 2. Expansion Area of Food and Agriculture Aquaculture. 3. Development of new sources of food production growth (expansion) require or be supported by the development of irrigation networks 4. Acceleration Food Diversification. 5. Developing of a new variety of adaptive to climate stress. 6. Development of Information and Communication Systems 7. Support Program,
INDONESIAN PROGRAM ON AGRICULTURE WATER MANAGEMENT 1. Establishing new irrigation system and improving the function of irrigation network. 2. Rehabilitation and optimization farming level irrigation channel (village irigation/ JITUT), rural irrigation channel (JIDES), micro water channel development (TAM), and exploiting pressure Irrigation (Drip and Sprinkler Irrigation) 3. Development of alternative and small scale of water resource (shallow and deep ground water, surface irrigation and management of irrigation participation 4. Development and water conservation Small dam, farming water reservoir (Farn pondg), and infiltration/recharge well. 5. Participatory irigation management (PIM) program , in developing the capacity and capability of WUA/WUAFs in implementation of partisipatory irrigation scheme management.
Conclusions 1. In order to assure food availability and sustainable agricultural development in each of the ASEAN countries and Japan need to have new inisiative and necessary steps a strategic cooperation in order to transfer a new technology on water management, developing of a new variety of adaptive to climate stress, etc 2. Capacity building program focus to address agriculture water efficiency (water-saving technology etc), adaptation of climate change as well as the activities and substances associated with the development of sustainable agriculture. 3. Building a regional food security and capacity information network, to administer information availability of food from each country with a focus on staple food (rice) by exploiting Asean secretariat as information processing centre and distribution.
