fair price schemes will come into being and <strong>the</strong> value of cultivation will be<br />

realised.<br />

Such concerted development at <strong>the</strong> local level will only be successful when<br />

backed by continued provision of improved planting materials and attention<br />

to quality aspects of products including product development, diversification<br />

and marketing.<br />

The current situation <strong>the</strong>re<strong>for</strong>e shows great promise <strong>for</strong> wider and better use<br />

of tamarind in a variety of situations: agro<strong>for</strong>estry, including much more<br />

testing of suitable intercrops in <strong>the</strong> early years of tamarind growth; in village<br />

co-operatives; and in small and medium sized plantations as a commercial<br />

crop.<br />

Even though <strong>the</strong>re are some limitations, tamarind could be better used in<br />

intercropping by improving tree architecture or changing spatial<br />

arrangements, as it will fit into various niches on small farms. Presently,<br />

sweet tamarind plantations are intercropped with annual crops in Thailand.<br />

Although desirable ideotypes have been proposed <strong>the</strong>se are at a preliminary<br />

stage of development. When such ideotypes are developed <strong>the</strong>y could have<br />

a direct impact on tropical agro<strong>for</strong>estry systems.<br />

Ano<strong>the</strong>r important aspect of tamarind is its food and medicinal value, which<br />

could safeguard food and nutrition security, alleviate poverty and improve<br />

health and <strong>the</strong> standard of living of rural populations. <strong>Tamarind</strong> is available<br />

when o<strong>the</strong>r food supplies are low, thus contributing significantly to <strong>the</strong><br />

nutrition of low-income rural households. Certain communities which<br />

consume cassava, yams or plantains as <strong>the</strong>ir chief source of carbohydrate,<br />

need more protein in <strong>the</strong>ir diet. <strong>Tamarind</strong> seed protein contains highly<br />

favourable amino acids and could complement methionine + cystine levels<br />

in <strong>the</strong> diet, to alleviate protein malnutrition which is widely prevalent in<br />

developing nations.<br />

Although medicinal values are claimed <strong>for</strong> various preparations made from<br />

tamarind leaves, pulp, flowers or both, only <strong>the</strong> antiascorbic and antioxidant<br />

properties of <strong>the</strong> pulp, laxative action of <strong>the</strong> fruit juice, and diuretic<br />

properties of <strong>the</strong> leaf sap are well established.<br />

11.2 Research and technology needs<br />

11.2.1 Understanding <strong>the</strong> genetic variation<br />

Very little is known about <strong>the</strong> genetic variation of tamarind. Due to its<br />

outbreeding nature and exceedingly wide distribution in <strong>the</strong> wild or<br />

naturalised state no concerted ef<strong>for</strong>t has been made to strategically sample<br />

populations and analyse patterns of variation. This could be done by taking<br />
