    Advocacy/Action Coalitions for Sustainable Agriculture & Natural Resource Management in Ecuador & Peru
    Andean Institution Team; Iowa State University; Heifer Project, Ecuador; Grupo Yanapai, Peru (2004)
    This presentation is on a study with the objectives of understanding how key natural resource management decisions are made and encouraging grassroots participation so such groups can use that knowledge in the decisions that most affect them.

    Community capitals: Poverty reduction and rural development in dry areas
    Flora, Cornelia B.; Thiboumery, A. (Jodhpur, India: Arid Zone Research Association of India, 2006)
    The lack of water in communities in arid lands is often related to the mal-distribution or absence of other resources. In the past, many communities responded to scarce resources by transhumance, building on cultural capital and social capital to produce sustainable livelihoods. But lack of political capital has reduced the options of transhumant communities. As they settle, new pressures are put on natural capital, beginning a downward spiral of other community resources. Successful efforts to reduce poverty in arid lands invest in many capitals in order to reverse the spiral. Attention to bridging and bonding social capital as an entry to poverty reduction is often more successful than built capital to provide bore holes or wells. Attention to cultural, human, social, and political, as well as natural, financial and built, is required for sustainable development in arid lands.

    Performance Measures for Pavement Assets under Performance Based Contracts
    Alyami, Zaid; Tighe, Susan L.; Gransberg, Douglas D.; Bianchin, Maria (2015-06-04)
    Over the past decade, there has been a movement in North America towards Performance Based Contracts (PBC). In PBCs, the client agency specifies defined minimum performance measures to be met or exceeded during the contract period. PBC operates through a continuing performance measurement and review systems against a set of minimum level of services (LOS). Therefore, performance measures in contract administration are fundamental to the successful usage of this type of contract. The paper presents a review of PBC focusing on performance measures. A review of the current state-of-the-practice is conducted to identify key performance measures employed by various agencies. In addition, a literature review of several road agencies in North America is conducted to evaluate the important physical attributes agencies are using as performance inputs to evaluate the overall condition of the road assets. Moreover, the study provides a review of performance specifications implemented by the Ministry of Transportation in Ontario (MTO) including Pavement with Warranty and Minimum Oversight Contracts. A monitoring framework of performance measures is presented. Finally, recommended performance measures for flexible, rigid pavements and granular shoulders are presented for the use in MTO's PBCs.
