Myanmar was not only a ‘fragile state’ by most definitions during the 1990s and 2000s, but was concurrently isolated as an international ‘pariah’. The complexity of this paradoxical combination of poverty, fragility, pro-economic growth polity and international isolation created an enigmatic context for international agencies, and one in which existing frameworks for development in ‘fragile states’ do not appear overly relevant. Nonetheless, Myanmar experienced a surprising level of development activity, with equally surprising signs of effectiveness. This paper explores this activity, identifying actors, roles, approaches, and modalities of interaction with structures and authorities found to be most effective. The paper is divided into four sections, offering an overview of the historical context, summarising field observations, considering the effectiveness of interventions, and discussing these observations in the light of fragile state policy.

This chapter examines the tensions present in approaches to development in Kyrgyzstan. It argues that development in this small post-Soviet republic has been approached primarily as formal statebuilding (Marquette & Beswick 2011), implying a belief that domestic political institutions and processes are the primary cause of fragility and that the adoption of democratic institutions and free market economic policies will result in development. The consequences of this inherently normative endeavour are explored in terms of the local political economy that has developed since independence and especially in the 2000s. Centrally, it is demonstrated how the competing interests and priorities of donors and local elite have undermined development efforts. On the basis of this analysis, it is suggested that rather than being framed as a failing or failed state, Kyrgyzstan is better understood as a case of failed statebuilding that cannot be remedied by the adoption of the current principles for development in fragile states situations, as adopted by the international community. Instead, the focus needs to be on facilitating the rebuilding of state-society relations both locally and internationally with a view to beginning to check the marketization of the state that has occurred.

A study was taken in a 1566 ha watershed situated in the Capivara River basin, municipality of Botucatu, São Paulo State, Brazil. This environment is fragile and can be subjected to different forms of negative impacts, among them soil erosion by water. The main objective of the research was to develop a methodology for the assessment of soil erosion fragility at the various different watershed positions, using the geographic information system ILWIS version 3.3 for Windows. An impact model was created to generate the soil's erosion fragility plan, based on four indicators of fragility to water erosion: land use and cover, slope, percentage of soil fine sand and accumulated water flow. Thematic plans were generated in a geographic information system (GIS) environment. First, all the variables, except land use and cover, were described by continuous numerical plans in a raster structure. The land use and cover plan was also represented by numerical values associated with the weights attributed to each class, starting from a pairwise comparison matrix and using the analytical hierarchy process. A final field check was done to record evidence of erosive processes in the areas indicated as presenting the highest levels of fragility, i.e., sites with steep slopes, high percentage of soil fine sand, tendency to accumulate surface water flow, and sites of pastureland. The methodology used in the environmental problems diagnosis of the study area can be employed at places with similar relief, soil and climatic conditions.

Environmental fragility models are important decision tools for policy makers as they help quantify environmental sensitivity and understand the relationship between human activities and environmental quality. The objective of this study was to evaluate three different environmental fragility models within the Brazilian rainforest region and to use the results to develop environmental zone classes. Two rural river basins located in Ibiuna, Sao Paulo state, Brazil, were studied. Input variables, including slope class, relief dissection rate, soil class, lithology, land cover, and climate data, were used to compute environmental fragility classes using three standard models. The model outputs were evaluated on their ability to accurately predict the most sensitive and least sensitive areas. The best models for each region were used to derive environmental zoning maps, including restoration priorities, best regions for agriculture, and areas with high needs for soil management. These maps will help support land use strategies for environmental restoration. This study provides insight into territorial ordering and management of environmental services with a regional perspective.

We report a theoretical study of the multiple oxidation states (1+, 0, 1−, and 2−) of a meso,meso-linked diporphyrin, namely bis[10,15,20-triphenylporphyrinatozinc(II)-5-yl]butadiyne (4), using Time-Dependent Density Functional Theory (TDDFT). The origin of electronic transitions of singlet excited states is discussed in comparison to experimental spectra for the corresponding oxidation states of the close analogue bis{10,15,20-tris[3‘,5‘-di-tert-butylphenyl]porphyrinatozinc(II)-5-yl}butadiyne (3). The latter were measured in previous work under in situ spectroelectrochemical conditions. Excitation energies and orbital compositions of the excited states were obtained for these large delocalized aromatic radicals, which are unique examples of organic mixed-valence systems. The radical cations and anions of butadiyne-bridged diporphyrins such as 3 display characteristic electronic absorption bands in the near-IR region, which have been successfully predicted with use of these computational methods. The radicals are clearly of the “fully delocalized” or Class III type. The key spectral features of the neutral and dianionic states were also reproduced, although due to the large size of these molecules, quantitative agreement of energies with observations is not as good in the blue end of the visible region. The TDDFT calculations are largely in accord with a previous empirical model for the spectra, which was based simplistically on one-electron transitions among the eight key frontier orbitals of the C4 (1,4-butadiyne) linked diporphyrins.
