This study is aimed to develop agroecological zone model (AEZ) integrated with the evaluation of land suitability in order to attain the food tenacity in Boyolali County, Central Java, Indonesia. This model is established through five steps. First, it is stocktaking and identifying biophysical land characteristic. The second step is compiling map of suitability of land commodities. The third is...

Identification and analysis of farmers’ vulnerability associated with their risk aversion degree is one of the necessary requirements for planning and reducing impacts of drought in Iran. So, this study was investigated three risk vulnerability parameters (economic, social and technical) among wheat farmers categorized in accordance with their risk aversion degree in the Mashhad County (Iran) b...

introduction drastic model is an index and overlapping model that has been designed for producing vulnerability scores for different points by combining several thematic layers. overlapping distinguished methods are themost applicable methods for evaluatingvulnerability of aquifers because they are cheap, they can directly reach a defined goal, the used data in the methods are accessible or can...

Microenteprises are increasingly recognized as major generators of income and employment in the developing world. Recent surveys suggest, however, that the sector is plagued by low productivity, leading some to claim that reducing impediments to microenterprise productivity is necessary to reduce urban poverty.

Although many have recognized the risks of software monocultures, it is not currently clear how much and what kind of diversity would be needed to address these risks. Here we attempt to provide insight into this issue using a simple model of hosts and vulnerabilities connected in a bipartite graph. We use this graph to compute diversity metrics as Renyi entropy and to formulate an anti-coordin...
