A Proposal to Expand the Community of Users Able to Process Historical Rainfall Data by Means of the Today Available Open Source Libraries

The paper presents a software architecture based on open source technologies, implemented by the authors in an experience of processing spatio-temporal data gathered by rain gauges spread across two regions of central Italy. The interest in the automatic processing of data about precipitation is widespread, however, today only an inner circle of stakeholders can think of taking advantage of the available open source libraries because a strong programming skill is required to use them. It is opinion of the authors that the implemented software architecture is suitable for expanding the community of users able to process “by themselves” historical precipitation data. The centre of the architecture is the technology of the spatial database management systems. They offer full support for the creation and management of a spatial database suitable to store the rainfall data usually spread out in several files. Moreover, they allow adding to such a repository a large set of ad hoc “objects” oriented to carrying out spatio-temporal computations on the precipitation. The stakeholders are only required to familiarize with the database’s objects and invoke their execution. A large part of the paper is devoted to show how the adopted conceptual setting can assist nontechnical users in carrying out personalized computations on rain gauges data. The computing needs posed by the experience described in this paper are common to many other areas of high social impact that involve spatio-temporal data, hence we believe that the implemented framework can be exported to them, keeping unaltered operational effectiveness

Uncertain Futures : Adaptive capacities to climate variability and change in the Lake Victoria Basin

The Lake Victoria basin (LVB) in East Africa can be considered a climate change hotspot because of its large rural population dependent on rain-fed farming. Drawing on extensive fieldwork (2007-2011) in rural communities along the shores of Lake Victoria in Kenya and Tanzania, I explore adaptive capacities to climate variability and change and discuss how they interrelate in situ. Using multiple methods, tools and techniques, including survey and rainfall data, individual and group interviews, interactive mapping of seasonal calendars and a multi-stakeholder workshop, I locate the place-based effects and responses to a number of converging climate induced stressors on smallholder farmers’ wellbeing and natural resources. Research findings show that adaptive capacities to climate variability and change in the LVB are complex, dynamic and characterized by high location-specificity, thereby signifying the value of using an integrative and place-based approach to understand climate vulnerability. Specifically, the study demonstrates how increased unpredictability in rainfall causes chronic livelihood stress illustrated by recurring and worsening periods of food insecurity, growing cash dependency and heavy disease burdens. The study also reveals that food and income buffers increase when and where farmers, particularly women farmers, collectively respond to climate induced stressors through deliberate strategies rooted in a culture of saving and planning. Nevertheless, the study concludes that smallholders in the LVB are facing a highly uncertain future with discernible, yet differentiated adaptation deficits, due to chronic livelihood stress driven by unequal access to fundamental adaptive capacities such as land, health, cash and collective networks
