Global Food Price Inflation: Implications for South Asia, Policy Reactions, and Future Challenges

The surge in global commodity prices of the past few years has presented a tremendous development challenge for South Asian countries. The large loss of income from the terms of trade shock has worsened macroeconomic balances, fueled rapid inflation, and hurt growth. Although commodity prices have come down recently, the benefits are being clouded by the emergence of a severe global financial crisis. The adverse consequences of the food price hike for the poor are large; the global financial crisis could further worsen the situation due to falling economic opportunities and government revenues. South Asian countries need to accelerate reforms to avoid facing a serious downturn in economic activity, investment, exports, and income. Governments in South Asia have responded by stabilizing domestic food prices through a number of short-term measures, tightened monetary policy to reduce inflation, and increased spending on a range of safety net programs for the poor. Some of the policies employed, such as export bans, are not consistent with the long-term welfare of the country or the region. Safety net interventions need to be made consistent with a longer-term poverty reduction strategy and fiscal sustainability. Most importantly, policy attention now needs to shift toward efforts to increase farm productivity, improve rural infrastructure, and lower the vulnerability of the poor.adverse consequences; adverse effect; Adverse Effects; Agricultural Productivity; Agriculture; average price; average prices; average productivity; basic needs; binding constraint; buffer stocks

Fiscal policyfor managing Indonesia's environment

The objective of this paper is to examine the role of fiscal policy in the management of Indonesia's environment. The aim is to develop a framework that will allow an examination of possible fiscal instruments and their relevance to Indonesia's context. It is important to note that fiscal policy is one possible area of policy intervention. Regulatory policies would also continue to play a major role. A comprehensive environmental management strategy will need to be based on a balanced combination of regulatory and fiscal policy instruments. Furthermore, a critical element underlying the successful implementation of this strategy will be the availability of an appropriate institutional mechanism. The paper provides an overview of Indonesia's key environmental issues followed by the framework for fiscal policy instruments. The Indonesian Government's progress on environmental management policies is examined briefly to provide background for the discussion of possible fiscal policy options. Finally, the paper provides a summary and conclusions.Water Conservation,Forestry,Water Resources Assessment,Environmental Economics&Policies,Water and Industry

Gravitational Decoupled Charged Anisotropic Spherical Solutions

The purpose of this paper is to obtain exact solutions for charged anisotropic spherically symmetric matter configuration. For this purpose, we consider known solution for isotropic spherical system in the presence of electromagnetic field and extend it to two types of anisotropic charged solutions through gravitational decoupling approach. We examine physical characteristics of the resulting models. It is found that only first solution is physically acceptable as it meets all the energy bounds as well as stability criterion. We conclude that stability of the first model is enhanced with the increase of charge.Comment: 20 pages, 6 figure
