We explore the connections between the concepts of governance and sustainability and discuss their possible roles in water and sanitation management systems (WSMS). We see governance as a decision-making process that drives the relationship between social institutions and the public affairs of a given society. We understand sustainability as a combination of spatial, temporal, and personal aspects, and we argue that this definition is more comprehensive than the traditional triple bottom line of economy, environment, and society. We combined these two concepts into a new conceptual framework of “governance for sustainability” that is theoretically sound and arguably appropriate to understand local WSMS. To illustrate this framework, we developed and estimated a Sustainable Water Governance Index (SWGI) for the city of Salta, Argentina. This aggregated index was calculated with data from literature, information from the city’s water company and other local institutions, field visits, and interviews. The SWGI for Salta obtained an overall score of 49 on a 0–100 scale, which fell into the “danger” range. We discuss the advantages and limitations of the method and conclude that aggregated indices such as the SWGI, complemented with contextual information, can be a helpful decision-making tool to promote more sustainable WSMS.

A comprehensive sustainability index for the assessment of water and sanitation management systems (WSMS) is presented. The index was based on a conceptual framework that perceives sustainability as a combination of territorial, temporal, and personal aspects. A set of sustainability indicators was selected in agreement within this framework, and the ‘Water and Sanitation Sustainability Index’ (WASSI) was built. The WASSI was used to assess the sustainability of the WSMS of the city of Salta, Argentina. Indicators were calculated from information gathered by several means including literature reviews, questionnaires, visits, and participatory workshops. The index was sensitive to detect variations between different aspects of the local WSMS. It was also relatively independent to the quantity and quality of the information available. The WASSI could be a useful tool to assess and improve sustainability of water and sanitation throughout the management systems.

Despite much deforestation in the past, the northwestern Argentinean province of Salta still has more than 6 million hectares of native forests. Land use conversion for agriculture is threatening these forests and the survival of indigenous populations and small-scale farmers. In November 2007, Argentina’s National Congress passed a law to regulate the management and conservation of native forests. This “Forest Law” required provincial governments to implement comprehensive and participatory Land Use Planning Processes (LUPPs). In this article, we describe and analyze, within a political ecology framework, the LUPP carried out in Salta. We focus on the conflicts derived from the different visions of development held by the interest groups involved, and we highlight some contradictions between their discourses and practices. We argue that “development” or “progress,” understood as a process of wealth and power accumulation linked to the possession of land and the production of agricultural commodities, was the leading ideology of political and economic elites in Salta during the LUPP. This ideology, and the established institutional power system behind it, was challenged when the National Supreme Court of Justice decided to suspend logging and deforestation activities on land claimed by marginalized ethnic and socioeconomic groups. We assess the implications of this ruling for the conservation of native forests and local livelihoods. As the final outcome of this case is still uncertain, a number of possible scenarios are presented and discussed.

The production of small amounts of well-stabilized biological sludge is one of the main advantages of upflow anaerobic sludge bed (UASB) reactors over aerobic wastewater treatment systems. In this work, sludge produced in three pilot-scale UASB reactors used to treat sewage under subtropical conditions was assessed for both stability and specific methanogenic activity. Stability of primary sludge from settling tanks and digested sludge from conventional sludge digesters was also measured for comparison purposes. Kinetic parameters like the hydrolysis rate constant and the decay rate constant were calculated. High stability was observed in sludge from UASB reactors. Methanogenic activity in anaerobic sludges was relatively low, probably due to the low organic matter concentration in influent sewage. Knowledge on sludge growth rate, stability, and activity might be very useful to optimize sludge management activities in full-scale UASB reactors.
