Smallholder Tree Growing in Philippine Back Yards: Homegarden Characteristics in Different Environmental Settings - Smallholder Tree Growing for Rural Development and Environmental Services - page 59

In the upland village Dy Abra no differentiation has been observed, with homegar-
dens mainly containing a true mixture of the tree species (see Table 2.4c) listed in
Table 2.4a. Moreover, like in Baliuag, most gardens have a higher diversity - and
also density - of species that spontaneously established themselves and are used for
timber, fuel wood, shade and fencing.
With regards to the non-tree crops, only the lowland villages show differentia-
tion through predominance of either vegetable (and-tuber)-based mixtures (i.e.,
Type 1, 2 and 3 in Moldero) or tuber-based mixtures (Type 4 and 5 in Malibabag).
For the other villages, a true mixture of the vegetables, tubers, fruits and spice crops
in Table 2.4a can be observed in at least 50 percent of all homegardens.

2.5.1 Differences in Management Aspects Among Land Use Zones

In Baliuag and Dy Abra where permanent streams for irrigation are outside reach
of most farmers, water shortage usually hampers production during the dry season
(Table 2.7). This is generally not true for most households in Malibabag and
Namnama, yet the quantities of “home-grown” food crops are limited and need
