Early peace settlements and state-building efforts led to transitional government and early democratic contestations including presidential elections in a hybrid state framework. This emerging democracy in a conflict-torn region is challenged by weak accountability and power imbalances between the three government branches. Over the past few years, the current ruling party started to engage with foreign companies to carry out exploration activities in onshore blocks utilizing existing information on the distribution of natural resources of oil, and gas and to lesser extent mining. Following an informal auction of selling licenses for resource exploration among various companies, Genel Energy amongst others;Somaliland has no competent institutions in managing revenues for long-term development due to two distinctive factors: 1) absence of strong legal and political frameworks specific to governance of extractive industry;2) weak fiscal regimes across spectrum of extractive companies, the state and investors.展开更多

It addresses why the “blessing” of abundant natural resources often turns into a “curse” in many countries and regions, focusing on the crowding-out effect of natural resources on human capital. According to our empirical analysis of provincial panel data from China, natural resource dependence is significantly and negatively correlated with human capital accumulation. The crowding-out effect of natural resources on human capital exists only in the central and western regions of China. Our introduction of an interaction term for natural resource dependence and public education investment underscores the possibility of investing in public education to reduce the crowding-out effect of natural resource dependence on human capital. The government should utilize the income of the natural resource sector to increase investment in education to enhance local human capital.展开更多

It is shown that the techniques of continuous time arbitrage and stochastic control theory may be used not only to value such projects but also to determine the optimal policies for developing managing. This paper describes a model for evaluating natural resource investments under uncertainty from a new perspective. The previous works in this field mostly regard the movements of natural resource prices as a continuous GBM process, which pays few attentions to the shock of unexpected bad news. Our model provides the first theoretical method to analyze the impact of such 'jump' on investment decisions. It concludes that the more frequently bad news happens, the earlier a project will be invested.展开更多

The overreaching goals of this research are to holistically reconstruct the archaeology of Singida by studying cultural processes over time and space. Equally important is to promote tourism in the Singida eastern axis and, to salvage the heritage assets of the region from total disappearance as evinced by the activities of modern day civilization, broadly, to shed more light about the past life ways, and the subsistence behaviours of our ancestors. Our recent archaeological reconnaissance conducted in January 2016 in Siuyu ward discovered rock paintings and a rock shelter with archeological potential (Ngaghe rock shelter), containing a large scatter of Later Stone Age (LSA) archaeological artifacts that are crucial to the unravelling of the prehistoric human behaviours in Singida. Preliminary results from our research revealed that Singida region is an ideal place for undertaking research on early human bio-cultural evolution from LSA times to the present. Data from this study will be utilized to re-write the history of Singida region, to make sure that it is sustained for future generations. Despite their rarity, uniqueness, scientific and aesthetic values, these heritage assets are neither protected by village nor regional by-laws. Before deliberate conservation measures are put in place, it is very important to have good records of the areas that are attractive to tourism, and their current state of preservation. These sites were undocumented by the previous researchers, and in certain circumstances are unknown even to the local people of the Siuyu ward. Although the archaeology of Singida east is much “terra incognita”, this article is timely, for promoting archaeo-tourism and raising public awareness on the archaeology of Singida. Additionally, this work provides a stimulus to the authorities to take action by introducing effective conservation measures for the sustainability of these priceless non-renewable resources.展开更多

The results show that the farmland tends to diminish on the whole, and forests, garden land, urban-rural settlements and land for enterprises and mining increase slowly. Based on the analysis of the dynamic relationship between land resources and population, we conclude that the land resources still can bear the current population in Liaocheng City, but the population development inflict critical pressure on the forest resources and water resources.展开更多
