Climatic signal in tree-ring chronologies of Cedrus deodara from Chitral Hindukush Range of Pakistan

Tree-rings are an important tool for the investigation of paleoclimatic records for regions or periods of time with no instrumental climatic data. However, the responses of different species and sites to various climatic parameters are unusual. In the present study, we developed tree-ring-width chronologies of Cedrus deodara from three different sites of Chitral Hindukush range of Pakistan. The study was conducted to understand tree-growth climate relationship and its applicability in proxy climate investigations. The chronologies covered the past 469 to 595 years, with a mean segment length (MSL) ranging from 148 to 223 years. Climatic data obtained from the three weather stations showed strong correlation and was found useful for tree-ring climate relationships. Correlation Function (CF) and Response Function (RF) analysis showed that spring precipitation (March–May) is a critical limiting factor for tree-ring growth, and temperature prior to November may also play a major role in affecting tree ring-growth. The results exposed that the three sites have continuous relationship indicated that only single species from different locations are affected by the same environmental variables and hence can be used in climate reconstruction in combination. The Cedrus deodara chronologies developed at different locations had several corresponding narrow and wide marker rings indicating a large macroclimatic response to regional climatic conditions. The current study suggests that the tree-rings of Cedrus deodara from the Chitral Hindukush range could be used to develop chronologies for the reconstruction of seasonal climatic variables.     

It’s hard to be down when you’re up: interpreting cultural heritage through alternative media

Heritage places are characteristically imbued with a multiplicity of meanings contingent on the specificities of the society, time and space in which such places are perceived. The interpretation of places also depends on the affordances of the representational medium through which these places are perceived and the ways in which such a medium is socially deployed and interpreted. Using the ancient settlement of Sirkap, located in modern-day Pakistan, as a case study, the present article demonstrates that a change in the representational medium entails a change in the interpretation of archaeological records. Most conventional historical accounts of Sirkap use two-dimensional site maps and city plans as the primary media to represent the urban fabric of the ancient settlement. These media lend themselves to interpreting the Block D Apsidal Temple complex as the dominant socio-religious structure in the affluent northern parts of the settlement. When the authors developed an interactive three-dimensional reconstruction of Sirkap using gaming technology – a medium that allows users, through their avatars, to explore the settlement from the standpoint of a pedestrian – it was immediately obvious that the aforementioned Block D Apsidal Temple complex did not demand such an interpretation. Instead, the authors argue that, at least in the affluent northern parts of the settlement, the northern gate, its adjacent fortifications, and the Block A stupa court were the dominant structures. Such an interpretation leads the authors to question the canonical understanding of the role of the state and its military apparatus in the socio-religious life of Sirkap.     

The Development Impact of NGO Activities in the Red Sea Province of Sudan: A Critique

This article examines the results of, and the prospects for, the declared shift of NGOs from relief operations to development activities in the Red Sea Province of eastern Sudan. Statistical and qualitative information contained in the reports of NGOs themselves provides the main data source on which the analysis is based. Although NGOs have been successful in conducting massive relief operations in the area, the article asserts that they have not yet and are not expected to achieve any tangible results on the development front. The main reason for this is the apparent misconception of development on the part of the NGOs as an isolated, localized activity which they can perform; another is the NGOs' failure to recognize the difference in the methods, means and prerequisites necessary for relief and for development; a third is the failure of NGOs to equip local institutions to absorb and/or sustain any achieved ‘development’, since most NGOs operate in complete isolation from governmental and traditional Beja institutions.     

Causes and Consequences of Inequality in Egypt

This study presents an analysis of various facets of inequality in Egypt using a political economy approach to understand how inequalities are reproduced in the Egyptian economy. It examines the drivers of income and wealth inequality, and the impact of uneven taxation. The paper highlights how the mismeasurement of top incomes can skew the measurement of inequality, and shows how Egypt has one of the biggest wealth gaps in the world. It investigates educational, gender, and healthcare inequalities and how they are reproduced across generations. The paper also highlights the disparity between urban and rural areas, which further contributes to inequality. It assesses why economic growth in Egypt has had limited success in reducing poverty and inequality, and analyzes how state and military interference in markets hampers the growth of the private sector. The paper concludes by examining how inequality, combined with a number of challenges that Egypt is facing, including increased authoritarianism, climate change, demographic pressures, and water security will likely exacerbate many of the country’s socioeconomic and political problems. Overall, the study argues that inequality remains a key concern that, if left unaddressed, may lead to social unrest and instability in the long term.
