With the growth of population, shortage of water resources, natural disasters, climate change, serious shortage of land resources and the development of urbanization and industrialization and impacts of other unfavorable factors, China's grain security issue has become a focus of public concern. Through the Chinese population quantity analysis and forecast of 2020 and 2030 the total demand of grain, comparison between total demand and current level of food production, China's grain problem is facing tremendous pressure. Water conservancy is the lifeline of agriculture and irrigation has great potential for grain production guarantee. Results for food safety in China made the following responses: First, the rational use of water resources, improve the efficiency of irrigation and grain yield per unit area. Second, multiple sectors such as agriculture, meteorology, soil, make a good combination of multiple disciplines for food security. Third, increase the peasants' production enthusiasm. Last, scientific and technological progress is the guarantee of grain production. In General, the issue of food security is national security, social stability, a top priority. The combination of our country's water resources crisis, limited rational development of agricultural water resources, improve the efficiency of irrigation, which will provide a guarantee for China agricultural water crisis, alleviating the shortage of water resources and increasing food safety assurance.

Sumber daya air memiliki peran yang besar bagi sektor pertanian. Air sebagai renewable resources digunakan untuk memenuhi produksi pertanian. Peningkatan produktivitas air pertanian memiliki peran yang penting dalam menghadapi kelangkaan dan kopetisi penggunaan sumber daya air, pencegahan terhadap kerusakan lingkungan dan ketahanan pangan. Tulisan ini bertujuan untuk melihat bagaimana kuantitas dan produktivitas sumber daya air pertanian di Indonesia secara umum. Berdasarkan data luas pertanian Indonesia tahun 2009-2013, luas sawah irigasi di Indonesia mencapai 4,81 juta Ha setara dengan laju peningkatan 9%. Apabila sawah irigasi ini dibandingkan dengan luas baku irigasi sebesar 12.335.832 Ha, maka persentase sawah irigasi hanya sekitar 38%, kondisi ini menggambarkan bahwa pemanfaatan air irigasi masih relatif rendah. Dilihat dari hasil data ketersedian air yang ada di 7 pulau-pulau besar yang ada di Indonesia Pulau Jawa mengalami permasalahan paling tinggi  dimana terlihat dari tingginya tingkat kebutuhan air tidak sebanding dengan ketersediaan air yang ada, sehingga akan berdampak kepada ketahanan pangan dan juga kondisi kesejahteraan masyarakat khususnya petani, dengan hal tersebut ada strategi dalam  dalam upaya peningkatan  penyediaan air dan produktivitas air yaitu dengan cara konservasi ekosistem hidrologis daerah aliran sungai (DAS), peningkatan efisiensi pemanfaatan air pertanian, redistribusi aset infrastruktur irigasi dengan mekanisme pendanaan dan insentif yang sesuai serta adanya harmonisasi antar sektor dan wilayahsetempat dalam pengelolaan sumber daya air pertanian.Water resources have a large role for the agricultural sector. Water as renewable resources is used to fulfill agricultural production. Increasing productivity of agricultural water has an important role in dealing with scarcity and competition in the use of water resources, prevention of environmental damage and food security. This paper aims to have a general view of quantity of agricultural water resources in Indonesia. Based on data on Indonesia's agricultural area in the year 2009-2013, irrigated paddy fields in Indonesia reached 4.81 million Ha, equivalent to the rate of 9% increase. If this irrigated rice field is compared to the irrigated raw area of 12,335,832 Ha, then the percentage of irrigated paddy fields is only around 38%, this condition illustrates that the utilization of irrigation water is still relatively low. Judging from the results of water availability data in 7 major islands in Indonesia that Java Island experiences the highest problems, which can be seen from the high level of water demand that is not proportional to the availability of water, so that it will affect food security and the condition of community welfare especially farmers, with this in mind there is an inner strategy in an effort to increase water supply and water productivity, namely by conserving watershed hydrological ecosystems , increasing efficiency of agricultural water utilization, redistributing irrigation infrastructure assets with appropriate funding mechanisms and incentives and harmonizing between sectors and regions in the management of agricultural water resources.

In recent years in yunnan province grain production increase in volatility,The high and stable yield of grain without good irrigation. Agriculture is water conservation, Industrial and agricultural water use ratio is about 1:4 in China, the main contradiction of supply and demand of water resources in agriculture.Due to other reasons, agricultural water supply reliability will be further reduced.In the case of agricultural water situation has deteriorated, in order to ensure and enlarge the scale of regional food production,urgently needs to research and develop to solve the contradictory between food production and supply of water resources in this area.
