A combination of netchain analysis and mapping the ‘challenges of innovation’ allows for innovation to be tracked as a non-linear and cyclical process, from a longitudinal and network structural perspective. These analytical tools enable the visualisation of changes in the structure of the innovation networks through time, such as the configuration of actors in the potato netchain, and the type of interdependencies between them that arise when facing, among others, production and marketing challenges.The analysis of the potato netchains from three cases shows different interdependencies - reciprocal, sequential and pooled - between actors. These interdependencies are facilitated by innovation intermediaries at certain challenges or stages in the cycle of innovation. Examples of facilitation include finding new actors who can bring new knowledge and/or benefit from the development of new products during the explorative phase of the innovation cycle, or the formalisation of contracts in an exploitative stage of the cycle of innovation. This facilitation of interdependencies is subsequently recognized as a source of value addition in the innovation process.Our findings also demonstrate how innovation networks evolve dynamically through time, and based on the presented evidence we conclude that an important role for innovation intermediaries is to keep the cycle of innovation in flux maintaining stability and change along the innovation trajectory.

However, many obstacles create poor conditions for developing national-level poverty assessments and maps. This paper reviews the experience of seven national-level assessments of poverty and food security in three continents.

We constructed an explanatory model of food consumption per person using household characteristics extracted from living standards measurement surveys (LSMS) of 1995 and 1998 [5],[6] . We deem households 'food poor' when their food consumption is insufficient to satisfy their nutritional requirements. We aggregated the households for each parroquia (district) and produced summary variables (and standard errors) that describe the distribution of food consumption. These variables include mean food consumption per person and the proportion of 'food poor' in the population of the parroquia – commonly known as the headcount ratio. Abstract Almost one fifth of Ecuador's inhabitants are undernourished [1] and over a quarter of children under 5 years of age are affected by chronic under nutrition [2] . This situation is deteriorating. Ecuador has been ...

Variety demand was conceptualized within the agricultural household framework and attributes were incorporated into the model according to the Lancaster (1966) consumer theory. Empirical analysis was based on primary data collected from two districts of Eastern Kenya using the stated preference and revealed preference methods. A factor analysis was used to cluster a set of common bean variety attributes that are highly preferred by households into those related to consumption flavour and yield related characteristics. The effect of consumption and production attributes and those of other factors were estimated through applying ordinary least squares regression. The study findings reveal that varietal adaptation to envi...

Specifically we attempt to improve disease potential maps of root rots in common beans, based on a combination of inherent susceptibility and the risk of exposure to critical weather events. We achieve this using simulated datasets of daily rainfall to assess the probability of heavy rainfall events at particular times during the cropping season. We then validate these simulated events with observations from meteorological stations in East Africa. We also assess the utility of remotely sensed daily rainfall estimates in near real time for the purposes of updating the risks of these events over large areas and for providing warnings of potential disease outbreaks. We find that simulated rainfall data provide the means to assess risk over larg...

The methodology, first described in Canada for solid tumors, estimates lifetime exposures to a number of potential toxic hazards or carcinogens. This pilot study confirms that the methodology, with the use of questionnaires and interviews, can estimate exposures to specific chemicals and shows some significant associations with myelodysplasia, including exposure to petrol or diesel compounds.

We also assess the utility of remotely sensed daily rainfall estimates in near real time for the purposes of updating the risks of these events over large areas and for providing warnings of potential disease outbreaks. We find that simulated rainfall data provide the means to assess risk over large areas, but there are too few datasets of observed rainfall to definitively validate he probabilities of heavy rainfall events generated using rainfall simulations such as those generated by MarkSim. We also find that selected satellite rainfall estimates are unable to predict observed rainfall events with any power, but data from a sufficiently dense network of rain gauges are not available in the region. Despite these problems we show that remotely sensed rainfall estimates may provide a more realistic assessment of rainfall over large areas where rainfall observations am not available, and alternative satellite estimates should be explored.
