Abstract
Purpose
The main purposes of this paper were to assess effects of smallholder farmers access to livelihood capital (e.g. land, livestock and water) on livestock water productivity (LWP) and to evaluate impacts of selected interventions in reducing livestock water demand (per unit of livestock product) and therefore increasing LWP.
Design/methodology/approach
A total of 203 sample farm households were selected in intensive and semi‐intensive crop‐livestock systems of Indo‐Ganga basin of India. A household survey was undertaken to capture data on land, water and livestock management. For the analysis, sample farms were clustered into poor, medium, better‐off. LWP is estimated as a ratio of livestock beneficial‐outputs (e.g. milk) to depleted‐water (i.e. evapotranspired water to produce livestock feed). Impacts of selected interventions, on LWP, were analyzed using scenarios developed on a spread sheet model.
Findings
The results showed different LWP values among farm‐clusters and levels of intensification. The intensive systems showed higher LWP than the semi‐intensive. In the baseline, dairy water demand to produce a liter of milk was higher than the world average: ranging between 1,000 and 29,000 L. Among the farm‐clusters, variation of LWP was system specific and affected by farmers' access to virtual water trading (i.e. milk and feed). Improving milk productivity, feed quality and feed water productivity reduced livestock water demand per liter of milk substantially and, therefore, the saved water can be used to augment ecosystem services that can mitigate the impacts of climate change.
Originality/value
This paper revealed that in the study systems LWP, in the business as usual scenario, is low. But by improving animal productivity, quality feed supply and water conservation substantial volume of water can be saved.

Abstract
Purpose
Tree fodder is an important constituent of livestock feed in the mid‐hills of Nepal, particularly so during the dry winter. The purpose of this paper is to compare the ranking of tree fodders by indigenous goat raisers to the selectivity of fodder by goats.
Design/methodology/approach
Fodder from six trees, namely, khanayo (Ficus semicordata), sal (Shorea robusta), kabro (Ficus lacor), pakhuri (Ficus globerrima), katus (Catannopsis tribuloides) and aanp (Mangifera indica) are used. Goat raisers rank the six fodders, giving 1 as the most preferred by goats and 6 as the least preferred. In addition, a feeding trial is carried out in which the six fodders are offered simultaneously to adult, castrated male and lactating, female local khari goats and intake of each fodder is determined.
Findings
Khanayo (1.00) is ranked highest by the goat farmers, followed by kabro (2.47), pakhuri (3.58), sal (4.16), aanp (4.56) and katus (5.21). Selectivity by the goats is highest in khanayo and kabro, intermediate in aanp and pakhuri and lowest in katus and sal. The correlation between farmer ranking and goat selectivity approaches significance (r=0.48; Mantel P<0.09). A significant correlation is found between fodder selections of male and female goats (r=0.68; Mantel P<0.01). Among components, fodder selectivity of goats is highly correlated (P<0.01) with calcium concentration only. Generally, goats select fodders high in calcium and crude protein and minimize intakes of fodders high in lignin and condensed tannins.
Originality/value
The indigenous population is knowledgeable about the fodder preference of goats but, in practice, they generally offer only one fodder species to the goats at a feeding. However, this paper shows that the goats consume and, most likely, require a mixed diet of tree fodders in satisfying their requirements of nutrients and energy while minimizing their intake of detrimental. This should be taken into consideration by the farmers when feeding their livestock.
