Afforestation is a key approach used to effectively prevent ecosystem degradation, which in itself is a key reason for the obstruction of sustainable societal development. In order to suppress sand and dust storms as a result of ecological environmental degradation in North China, the Government of China has sanctioned the planting of a large number of trees in Inner Mongolia. However, water resources in the Inner Mongolian Plateau are insufficient to sustain this effort because such a large number of trees consume a large amount of water, which also significantly increases evapotranspiration. This study uses spatiotemporal trend analyses and abrupt change analyses to determine the effects of afforestation on water resource variations in the Inner Mongolian Plateau. Results show that even though water resources in Inner Mongolia fluctuate, this resource has generally exhibited a declining trend from 1980 to 2015, corresponding to the NDVI trend. On spatial-temporal scales, water resources decreased significantly in the eastern section of the plateau, especially in the Horqin District and the Hulunbuir Plateau. By contrast, water resources increased as a whole in the western section of the plateau (Alxa Plateau). Driving analysis results show that water resource variation is mainly due to the contribution of change in precipitation (positive effect), which accounted for 39.35% of total changes in water resources, followed by the evapotranspiration (negative effect). In other words, afforestation with the primary aim of improving ecosystem has effectually upset the water resource balance of Inner Mongolia Plateau.

The economic development in Indonesia from period to period until now is increasing because Indonesia is very rich with natural and human resources, only quality human resources need to improve their quality in order to be able to develop better economy in the future, however unemployment and poverty rate of Indonesia is still high compared to some other countries in the world, therefore it is necessary jointly between individual society, private and the government has maximum efforts to reduce unemployment and poverty in Indonesia, by increasing the growth of gross domestic product (GDP) contribution by business field can reduce poverty level in Indonesia. The result of multiple regression analysis shows that the contribution of GDP according to business field can decrease poverty level in Indonesia. This condition indicates that agriculture, forestry, fishery sector has a negative effect on poverty rate in Indonesia which means any decrease in agriculture, forestry, fishery by one unit affect the decrease of poverty level of 0.203 at constant -7,70, while the other three factors mining and quarrying, processing industry factor and trade factor have a positive effect on poverty level which means that every increase of one unit leads to a significant increase in poverty not yet able to reduce poverty level but has significant influence on all variables to poverty level in Indonesia. The results of multiple correlation coefficient analysis indicate that from each sector, agriculture, forestry, mining fishery, excavation, processing industry and trade are very strong together that is equal to 97,70%, besides coefficient value of determination equal to 0,96% whereas the remaining 4% of the poverty rate is influenced by other factors

India is rich in natural water resources, but because of the uneven distribution of resources and improper management, the major part of the country suffers from drought almost every year. The present study is based upon the inappropriate management of water resources in the urban and rural area of Jabalpur. The present paper intends to find out the actual condition of management of water resources by the municipal corporation of Jabalpur, whether the citizens of Jabalpur are benefitted through the policies made by the government for the equal distribution of water resources, are the policies adequately implemented and monitored once they are made?The data has been collected from secondary and primary sources, and simple percentage method has been used to analyze the collected data. The outcome of the study reveals that the government is trying to manage the water resource and is concentrated on the equal distribution of water in both urban and rural areas. Many policies have been prepared by the local government, but ineffective monitoring is the leading cause of improper management of water resources.

The main objective of this paper was to examine the impact of domestic debt on economic growth in Tanzania for the period 1990 to 2015 using Ordinary Least Square (OLS) regression method to estimate the effects. The study finds that there is an inverse but insignificant relationship between domestic debt and the economic growth of Tanzania as measured by GDP annual growth. The inverse relationship between domestic debt and GDP may be caused by different factors such as; increased trend in domestic borrowing, government lenders’ profile dominated by commercial banks and non-bank financial institutions which promotes the “crowding out” effect; the nature of the instruments used by the government ; the improper use of the domestic borrowed funds which may include funding budgetary deficits, paying up principal and matured obligations on debt, developing financial markets as well as fund other government operations. Other control variables relate with the GDP as predicted. For example, Inflation (INF) has a negative effect on the GDP growth rate, but the relationship is not statistically significant, while gross capital formation (GCF) has a positive statistically significant effect on GDP growth rate. Furthermore, foreign direct investment (FDI) showed a positive effect on the GDP growth rate and export (X) has a positive effect on GDP growth rate, and the relationship is statistically significant explaining that if a country applied an export-led growth economic strategy it enjoys the gains of participating in the world market. This means that an increase in export stimulates demand for goods which leads to increase in output, and as a country’s output increases, the economic performance also takes a similar trend. Finally, government expenditure (GE) had a negative effect on the GDP growth rate which may be explained by the increased government expenditures which are funded by either tax or borrowing. Therefore, what is required for countries like Tanzania is to have better debt management strategies as well as prudential financial management while maintaining to remain within the internationally acceptable debt level of 45% of GDP and maintain a GDP growth rate of not less than 5%. It is important for the country to realize from where to borrow from, the tenure, the risks involved and limitations to borrowing and thus set the right balance of combination of both kinds of debt. Another requirement is to properly utilize the borrowed funds. The central government’s objective should be to use the funds in more development-oriented projects that bring positive returns to the economic development.  The government should not only create a right environment and policies for investment to attract investment from domestic and foreign sources but also be cautious about the kind of investments that the foreign investors make.

This research is based on the fact that the state of economic growth in Indonesia tends to fluctuate, even more often decrease. This is because the government policy is not appropriate to improve the economic growth of Indonesia. This study aims to determine and analyze the factors of foreign direct investment, inflation, international trade, and government expenditure that affect economic growth in Indonesia. The problem in this research is due to the limited fund in economic development both structure and infrastructure so that economic growth tends to decrease. Therefore, appropriate strategies must be taken to overcome the limitations in promoting economic growth. From this problem, this research aims to see how big influence of foreign direct investment (FDI), inflation (INF), international trade (NX) and government expenditure (GE) variable to economic growth. The data used in this study is secondary data (periodical data) in the period of observation 1996-2014 obtained from the World Bank and Statistics of Indonesia. To identify the influence of the variables used in this study used the VAR (Vector Autoregression) method. The results of this study show that equation regression shows that FDI (-1) has a negative influence on economic growth and FDI (-2) has a positive effect on economic growth, INF (-1) and INF (-2) have positive effects on economic growth , Variable NX (-1) has a positive effect on economic growth but NX (-2) has a negative effect on economic growth, and GE variable (-1) has a positive effect on economic growth while GE (-2) has a negative effect on growth Economy.

Merri Anitasari, Ahmad Soleh; Pengaruh Pengeluaran Pemerintah Terhadap Pertumbuhan Ekonomi Di Provinsi Bengkulu. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh dari pengeluaran pemerintah terhadap pertumbuhan ekonomi di provinsi Bengkulu dengan menggunakan data sekunder periode pengamatan tahun 2001-2012 yang diperoleh dari Badan Pusat Statistik. Hasil analisis dengan menggunakan SPSS 16 menunjukkan bahwa pengeluaran pemerintah berpengaruh positif dan signifikan terhadap pertumbuhan ekonomi di provinsi Bengkulu. Jika pemerintah menaikkan pengeluaran pemerintah sebesar 1 miliar rupiah, maka akan dapat meningkatkan pertumbuhan ekonomi sebesar 1,17 % per tahun. Sedangkan pengaruh pengeluaran pemerintah terhadap pertumbuhan ekonomi di daerah kabupaten/kota menunjukkan bahwa dari jumlah 10 kabupaten/kota di Provinsi Bengkulu, kabupaten Rejang Lebong dan kota Bengkulu yang memiliki hasil bahwa pengeluaran pemerintah berpengaruh positif dan signifikan terhadap pertumbuhan ekonomi di daerahnya. Kabupaten Bengkulu Utara memiliki pengaruh yang negatif sedangkan 7 kabupaten lainnya memiliki hasil yang positif namun tidak signifikan. Sebagian besar kabupaten di Provinsi Bengkulu dikategorikan sebagai daerah yang baru membangun yang merupakan hasil pemekaran pasca pemberlakuan otonomi daerah. Sehingga dalam jangka pendek pengeluaran pemerintah dianggap belum mampu menstimulus kegiatan sektor-sektor perekonomian serta memacu pertumbuhan ekonomi di daerah tersebut.Merri Anitasari, Ahmad Soleh; Impact of Government Spending on Economic Growth In Bengkulu Province.

The purpose of this study is to examine the influence of political connections on firms’ performance by controlling the effect of board attributes and firms’ characteristics. Specifically, it is argued that politically connected firms enjoy a lot of benefits from the government and said to provide greater chances for the firms to increase their wealth. By using 156 public listed firms between the study period of 2012 to 2017, this study maps out political connection based on the 13th Malaysian general election. The results reveal that the appearance of political connections on board gives significant and negative effect on Tobin Q, while significant and positive effect on Return on Asset (ROA) and Return on Equity (ROE). Board independence is also significant to firms’ performance. This result implies that political connection is a favour for a better firm’s performance and not to firm’s value. The findings have an important implication to investors as it suggests that firms with political connection on board perform better.

The influence of climate change and human activities on hydrological elements has increased along with increasing dependence on water resources. Therefore, quantitative attribution of hydrological elements has received wide attention. In this study, the double mass curve (DMC) is used to assess the abrupt change point of the hydrological data series, based on which the periods with/without large-scale human activities causing runoff attenuation are separated. The land use transition matrix is then employed to analyze the land use types at different historical stages, and the sensitivities of the runoff attenuation to different land use/cover change (LUCC) categories are quantified. A soil and water assessment tool (SWAT) model that considers the underlying surface is constructed with six designed scenarios of different climate and LUCC conditions. Taking three typical mountainous basins in North China as the study area, the quantitative contributions of climate change and human activities to the water resources are identified. The results of the study have brought enlightenment to the water resource sustainable utilization and management in North China, and the methodologies can be transferred to runoff attribution analysis in water shortage areas.
