Carp-SIS-Prawn polyculture(2008-2011)

Project objectives

a. to improve the health and nutrition of women and children through increased intake of nutrient-dense SIS

b. to increase household income

c. to empower women

Household Income

Household consumption to improve nutrition

Partial harvesting of SIS for household consumption and improvement of nutrition level
