National Evaluation of User Profiles in Aquaculture

One problem with information delivery to a specific segment of the agricultural community is identifying the characteristics and needs of the end-user. Such a profile could be used for evaluation of the products or services provided. The Aquaculture Information Center of the National Agricultural Library was able to construct to such a profile based on historical data as well as current assessments from several United States aquaculture information groups. Analysis of this data provided specific and general direction for future products and services within the aquaculture information community. Findings also highlighted the important need for further tracking of such data, emphasis on continued networking among information groups, and creation of formal guidelines for aquaculture information access for the end-user.

Gendered participation in water management: Issues and illustrations from water users‘ associations in South Asia

The widespread trend to transferirrigation management responsibility from the stateto communities or local user groups has byand large ignored the implications ofintra-community power differences for theeffectiveness and equity of water management. Genderis a recurrent source of such differences. Despitethe rhetoric on womens participation, a review ofevidence from South Asia shows that femaleparticipation is minimal in water usersorganizations. One reason for this is that theformal and informal membership criteria excludewomen. Moreover, the balance between costs andbenefits of participation is often negative forwomen because complying with the rules and practicesof the organization involves considerable time costsand social risks, whereas other ways to obtainirrigation services may be more effective for femalewater users. Although effective, these other andoften informal ways of obtaining irrigation servicesare also typically less secure. More formalparticipation of women can strengthen womensbargaining position as resource users withinhouseholds and communities. Greater involvement ofwomen can also strengthen the effectiveness of theorganization by improving womens compliance withrules and maintenance contributions. Furtherdetailed and comparative research is required toidentify the major factors that affect womensparticipation and control over resources, ifdevolution policies are to address the tensionbetween objectives of transferring control overresources to community institutions, and ensuringthe participation of all members of the community,especially women.
