INTRODUCTIONINTRO UCTION1. Asia Monsoon region  ‐more than half of the world’s 

population resides, p p ,2. Rice have been cultivated over thousand years ‐most 

important staple crop; adapted to the climate and has supported large population. 

3. The paddy systems have provided not only food but also a broad benefits in the social economic environmental andbroad benefits in the social, economic, environmental and cultural aspects to the region.

4. Perception that large scale paddy planting in Asian p g p y p gcountries are contributing to degradation of the environment through destruction of ecosystem and 

h i imethane gas emission. 5. Overlooked the importance of paddy field in providing 

many other benefitsmany other  benefits. ###

Food security in Asia Region

1. Food price spikes in 2008 exposed vulnerability in the food supply demand 

2. Raising demand resulted from population growth and economic development. 

3. Increasing instability of food production associated with climate change

4. The key to address food security is through effective use of limited water and land resources

5. In the Asia Monsoon region, rice is most important staple crop

MULTIFUNCTIONAL ROLES OF PADDY FIELDS

1. The hydrological behavior of paddy fields resembles that of y g p ynatural wetlands, paddy fields are able to provide most, if not all, of the environmental and other benefits provided by wetlands. 

2. When planned and managed properly, sustainable paddy farming can provide more benefit than adverse effectsfarming can provide more benefit than adverse effects. 

3. Whilst producing rice to secure food supply, paddy fields provide many environmental benefits such as flood p ycontrol, sediment control, groundwater recharge etc.

4. Paddy field is very much part of Asian culture and has, in recent years, been successful sites for eco‐tourism in many parts of Asia.

MALAYSIAN PILOT STUDY: FLOOD AND SEDIMENT CONTROL IN LOW‐LAND PADDY FIELDSCONTROL IN LOW LAND PADDY FIELDS

1. Cost replacement method was used to equate the p qflood control and sediment control value of paddy field to equivalent flood prevention and p y q priver desilting projects. 

2. Next a national projection was provided. p j p3. It was found that the values of flood and 

sediment control were conservatively estimated yto be 440 mil USD and 12 mil USD respectively. 

4. This is almost as significant as the rice 4 gproduction value of about 472 mil USD annually. 

5. The study thus successfully proved the worth of 5 y y pmulti‐functionality of paddy fields.                ###

sediment control in paddy fields 

1. INWEPF is in the process of compiling the findings from case studies such as above from member countries i t G id liinto  Guidelines

2. Through early finding of these case studies, it was f d th t diff t l d d dd l tifound that different landscape and paddy planting practices, some environmental services may differ f t t t i t ifrom country to country or region to region. 

3. After a series of technical discussions and review, a ifi d t d d t l f t tunified standard protocol for monetary assessment 

will be produced.4 G idelines the flood and sediment control f nctions4. Guidelines the flood and sediment control functions 

had been finalized while others are  in progress.     ###

CONCLUSION1 Padd field and rice prod ction is er important for food sec rit1. Paddy field and rice production is very important for food security, 

poverty alleviation  and environment of Asian Region

2. There is a need to balance in increase of agricultural productivity with the environmental protection as the increase in productivity most of the time give effects to environment, water demand and poor farmers. 

3 Paddy field and irrigation system provide various benefit socially3. Paddy field and irrigation system provide various benefit, socially, economically, environmentally and culturally  through its multifunctional roles and uses.multifunctional roles and uses. 

4. Evaluation and conducting monetary assessment is required to quantify the value of the functions to consider during overall project evaluation.  

5. INWEPF has taken the task to promote efforts for sustainability and multi functionality of paddy system Providing guidelines forand multi‐functionality  of paddy system. Providing guidelines for monetary assessment for flood control and sediment in paddy fields is one of such efforts.                                                             ###
