The challenge of achieving basal energy, iron and zinc provision for home consumption through family farming in the Andes: a comparison of coverage through contemporary production systems and selected agricultural interventions

Table 8 Energy, iron and zinc balance outcomes in status quo and intervention scenarios

Scenario	% Households with negative coverage (n = 165)			Average household balance per day^a (n = 21)
Scenario	Energy	Iron	Zinc	Energy (kcal)	Iron (mg)	Zinc (mg)
Status quo	13.9	37.6	23.6	−3903	−90	−34
1. Potato yield increase^b	9.1	29.7	16.4	−1999	−77	−27
2. Biofortified potatoes^c	13.9	33.9	20.0	−3903	−87	−32
3. Microlivestock^d	13.9	35.8	22.4	−3858	−89	−33
4. Combined (1 + 2 + 3)	9.1	26.1	15.2	−1954	−77	−25
