Take home messages
1. Tremendous potential to greatly increase productivity, nutritive value, profitability & resilience of production systems in the polders• agricultural systems (rice & non-rice)• aquacultural systems• rice-aquaculture systems• homestead production systems
2. To unlock this potential need to invest in • improved water mgt• with special emphasis on drainage mgt (the entry point) and infrastructure inside the polders
3. Community co-ordination is critical to achieving this – needs community ownership & to be community-driven

For high rice yield & cropping system intensification in polders we need rice varieties with…..
1. High yield potential
2. Tolerance to stresses, especially• water stagnation (30-50 cm, week...months)• salinity• submergence after transplanting• singly and in combination
3. Early maturity (for system intensification)
4. Preferred grain quality
13
Rice variety evaluation in farmers’ fields
Tolerance to water stagnation for aman essential throughout coastal zone This crop experienced deep water (up to 44 cm) for several weeks (4.6 t/ha)

BRRI dhan54
Amal-Mana ~4 t/ha(Water stagnation tolerant)

Submergence tolerance needed for aman (& aus)(example in a shrimp-rice gher)

Implemented on-farm for 2 years, 4th crop – polder 30 – but NOT to potential;Community water management, cropping system synchronisation, adoption challenges
24
With improved varieties & cropping system intensification, productivity can be increased 2 to several-fold
Widespread implementation requires improved water management
Water mgt ingredients for a Green Revolution in the Polders
1. Separation of lands of higher & lower elevation (mini-water mgt units)
Prevent accumulation of drainage in lowlands – enable rainy season HYVrice

The consequences of late rabi crop establishment – low yields or complete failure due to early kharif rains
- high yield, high value crops out of the question (e.g. sunflower, maize)
AFTER RICE HARVEST – some areasLow input crops – late sown (Feb/Mar) because of late rice harvest

5. De-silting of khals ..Increases storage capacity for irrigation when river too saline..Facilitates drainage

Khals within polders vary greatly in size, can store fresh water during the dry season, but often heavily silted up (some no longer exist), blocked…

6. “Early” establishment of boro rice after aman (sow mid-Nov)
Reduces storage requirement for fresh water to finish the crop off after the rivers become too saline
35Polder 30 - sufficient storage for 15-20% of land to grow boro rice
- desilting of khals roughly double the possible boro rice area

Rice-aquaculture systemTherefore 2 water depth treatments (low & high) in rice-aquaculture
Saline water needs to be drained in July to allow leaching of salt by rainfall prior to rice transplantingBrackish water aquaculture production is higher if saline water is kept for longer
Need shallow water after transplanting rice (<20 cm)This is very shallow for aquaculture (importance of trenches)
Better rice productivity with shallower waterBetter aquaculture productivity with deeper water

Impact of crop diversification in shrimp ghers during cycle 1 (55-65 days)
57
Key challengesMarkets• Scarcity of quality shrimp and fish seed• Lack of quality feed in local market
Aquaculture management• Prevention of escaping cat fish through dikes• Aquatic weed control
Community• Poor canal network for filling ponds & drainage
(need community system)• Poaching risk increases (need to increase
productivity of all ghers to lessen predation of individual ghers)
58
Other improvements
You can make your saline gher dike green and environment friendly by adding trees
59
Other improvements
Vegetables can be grown on gher dikes during wet season60
Other improvements
Local variety of grass grows very well on saline gher dikes which can be used as fodder
61
Take home messages
Farmer practice very low profit Improved practice increases profit 3-5 times Shrimp monoculture can be profitable, but highly risky Polyculture provides resilience against failure of
shrimp – profitable even if ALL shrimp die We failed to get high yields of rice because of inability
to drain (& irrigate) when needed Need good community water management systems for
both aquaculture and rice – for intake and drainage as needed
Neighbouring farmers are beginning to adopt improved practices

Bangladesh West Bengal
Food requirement satisfied by own products (HFS + Field)
• Only ~20% hh with <1 ha land are meeting their year round food requirement from own production, suggests opportunity for vertical integration of the systems
• Over all households in West Bengal with higher amount of land supported their food requirement better than Bangladesh

Correlation between production and consumption
HFS productivity ($/ha/year) in different salinity
Preliminary results says
YES
Does Homestead production system holds promise ???
Key remarks
Homestead production system contributes better in meeting household food security of Functionally Landless groups while small households are more dependent on non-homestead productionHFS productivity significantly lower in high salinity areas than low salinity areas in both the countries
Need to focus more research on improving productivity in saline areas
No specific factors had significant role in regulating HFS productivityMost of the people are not self sufficient/food secured Raising awareness on the importance of nutrition is crucial There are opportunities to further improve the status of food security particularly in the high saline zone

Objectives:to improve nutrition & income through increasing productivity of homestead ponds to empower women thru participatory action research (PAR)
Key pond interventions:– fish species to increase production & consumption– feeding strategies to avoid water pollution– women capacity building

The big ones: 1. How can we implement improved community management to
achieve the benefits of improved production systems? (about water; agricultural cropping systems, aquaculture systems)
2. Achieving no. 1 requires additional investment in drainage/water management infrastructure inside the polders – is it economic?, what’s the optimum?
Many others specific to components of improved systems:
• rice varietal improvement (e.g. short duration, cold tolerant boro)• nutrient cycling in rice-shrimp systems• homestead production systems (e.g. pond-ecosystem approach)• sustainability of groundwater pumping for boro rice• establishment of rabi crops • aquaculture in saline areas
Research questions for the future (many)
115
Take home messages
1. Tremendous potential to greatly increase productivity, nutritive value, profitability & resilience of production systems in the polders• agricultural systems (rice & non-rice)• aquacultural systems• rice-aquaculture systems• homestead production systems
2. To unlock this potential need to invest in • improved water mgt• with special emphasis on drainage mgt (the entry point) and infrastructure inside the polders
3. Community co-ordination is critical to achieving this – needs community ownership & to be community-driven
