Integrating gender into index-based agricultural insurance: a focus on South Africa

Index insurance is an agricultural risk management tool that can provide a safety net for smallholder farmers experiencing climate risk. While uptake and scale-out of index insurance may be slow among smallholders, we can learn from experiences that demonstrate where crop insurance can protect smallholders’ livelihoods from climate risk. Integrating gender into climate risk management is necessary to ensure that the benefits of index insurance are experienced by both men and women. A dedicated intention to integrate gender may be required. Taking South Africa as a case study, the potential for gender-sensitive index insurance scale-out among smallholders is investigated

Assessing Romanian financial sector stability: the importance of the international economic climate

The aim of this paper is to develop an aggregate stability index for the Romanian financial system. The index which is meant to enhance the set of analysis used by the central bank to assess the financial stability accurately reflects the financial stability dynamics and the periods with financial turbulences during 1997-2007 in Romania. By the application of a technique which enables the measurement of the components’ contribution to the aggregate index volatility, we show that some individual stability indicators require a close monitoring by the authorities in order to detect the instability periods. Several attempts to set up a financial stability aggregate index can be found in the literature, but none of these studies took into consideration the spillover effect between different financial markets. One of the contributions of our paper is the introduction within the aggregate index of an indicator capable of highlighting the international economic climate. The deterioration of the world economic climate can represent the background for the contagion phenomenon. The outcome of the study shows an improvement of the Romanian financial stability during the analysed period. The aggregate index volatility also decreased starting with 1999. The financial vulnerability and financial soundness indicators have a significant contribution to the volatility of the aggregate index in the periods foregoing the crisis appearance. On the contrary, the volatility of the world economic climate indicators is reduced before the crisis, rising immediately after its burst out.financial stability, quantitative methods for assessing systemic stability, aggregate financial stability index, world economic climate index

AODP global climate index: 2012 results

Climate change represents a unique challenge to asset owners and their ability to manage global, cross-sectoral, systemic risks. It demands change management across every function of a fund.Many asset owners have already acknowledged the need to build capacity and challenge traditional industry practices in order to manage climate change. However, there has so far been little information to inform the market on what constitutes best practice let alone to enable consumers to differentiate between funds.It is against this background that Asset Owners Disclosure Project (AODP) operates its Global Climate Index, so that stakeholders of all kinds, including the beneficiaries themselves, can see which funds are leading and which are lagging - providing data that is critical to the efficient operation of the market

THE INVESTMENT CLIMATE IN 16 INDIAN STATES

In this paper, the author attempts to identify the characteristics of the business climate in India that can help explain the different performance of individual states in terms of investment and growth. The paper develops a new Investment Climate Index aimed at summarizing the aspects of the business environment that entrepreneurs consider when deciding whether to invest. Using this index, the author explores the investment climate in several typologies of Indian states and identify the key features of a poor business environment in India. The analysis shows that infrastructure and institutions remain the main bottlenecks in the country's private sector development. More specifically, power, transportation, corruption, tax regulations, and theft are major factors explaining the poor business environment in some Indian states. Infrastructure appears to be the single most important constraint, as it is particularly binding in states that show low levels of domestic investment and GDP growth.affiliated organizations; bank financing; bottlenecks; business climate; business environment; business regulations; collateral; Cost of finance; data availability; domestic investment;

A Flexible Global Warming Index for Use in an Integrated Approach to Climate Change Assessment

Global Warming Potential (GWP) is an index used to measure the relative accumulated radiative effect of a tonne of greenhouse gas (GHG) compared to that of a 'reference' gas (CO2). Due to the different lifetimes of the GHGs, the GWPs are often measured over a fixed and long period of time (usually 20, 100, or 500 years). The disadvantage of this time-approach is that the index may give a good indication of the relative average effect of each GHG or total radiative forcing over the chosen time horizon, but it may not describe accurately the marginal contribution of each GHG to the overall climate change at a particular point in time, and conditional on a particular climate change policy scenario which is being considered. In this paper, we propose an alternative approach which measures the relative contribution of each GHG to total radiative forcing more accurately and in accordance with the current policy context being considered. We suggest the use of a marginal global warming potential (MGWP) rather than the existing (total or cumulative) GWP index. The MGWP can be calculated accurately and endogenously within a climate model. This is then linked to the marginal abatement cost (MAC) of the gas, estimated within an economic model linked to the climate model. In this way the balancing of the benefits and costs associated with the reduction of a unit of emission of the GHG can be achieved more accurately. We illustrate the use of the new approach in an illustrative experiment, using a multi-sector multi-gas and multi-regional computable general equilibrium economic model (GTAP-E) coupled with a reduced form climate change model (ICLIPS Climate Model, or ICM). The results show that the new approach can significantly improve on the existing method of measuring the trade-offs between different GHGs in their contribution to a climate change objective.

U.S. East Coast Trough Indices at 500 hPa and New England Winter Climate Variability

Using monthly gridded 500-hPa data, two synoptic indices are defined to better understand the principle mechanisms controlling intraseasonal to multiannual winter climate variability in NewEngland (NE). The “trough axis index” (TAI) is created to quantify the mean longitudinal position of the common East Coast pressure trough, and the “trough intensity index” (TII) is calculated to estimate the relative amplitude of this trough at 42.5°N. The TAI and TII are then compared with records for NE regional winter precipitation, temperature, and snowfall with the goal of understanding physical mechanisms linking NE winter climate with regional sea surface temperatures (SST), the North Atlantic Oscillation (NAO), and the Pacific–North American (PNA) teleconnection pattern. The TAI correlates most significantly with winter precipitation at inland sites, such that a western (eastern)trough axis position is associated with greater (lower) average monthly precipitation. Also, significant correlations between the TAI and both NE regional SSTs and the NAO suggest that longitudinal shifting of the trough is one possible mechanism linking the North Atlantic with NE regional winterclimate variability. The NE winter temperature is significantly correlated with the TII, regional SSTs, and the NAO. While the PNA also correlates with the TII, NE winter climate variables are apparently unrelated to the PNA index

Tropical–North Pacific Climate Linkages over the Past Four Centuries

Analyses of instrumental data demonstrate robust linkages between decadal-scale North Pacific and tropical Indo-Pacific climatic variability. These linkages encompass common regime shifts, including the noteworthy 1976 transition in Pacific climate. However, information on Pacific decadal variability and the tropical high-latitude climate connection is limited prior to the twentieth century. Herein tree-ring analysis is employed to extend the understanding of North Pacific climatic variability and related tropical linkages over the past four centuries. To this end, a tree-ring reconstruction of the December-May North Pacific index (NPI)-an index of the atmospheric circulation related to the Aleutian low pressure cell-is presented (1600-1983). The NPI reconstruction shows evidence for the three regime shifts seen in the instrumental NPI data, and for seven events in prior centuries. It correlates significantly with both instrumental tropical climate indices and a coral-based reconstruction of an optimal tropical Indo-Pacific climate index, supporting evidence for a tropical-North Pacific link extending as far west as the western Indian Ocean. The coral-based reconstruction (1781-1993) shows the twentieth-century regime shifts evident in the instrumental NPI and instrumental tropical Indo-Pacific climate index, and three previous shifts. Changes in the strength of correlation between the reconstructions over time, and the different identified shifts in both series prior to the twentieth century, suggest a varying tropical influence on North Pacific climate, with greater influence in the twentieth century. One likely mechanism is the low-frequency variability of the El Nino-Southern Oscillation (ENSO) and its varying impact on Indo-Pacific climate.</p

Which climate indices are relevant for predicting the response of tropical forests to future climate scenarios ?

Climate models predict a range of changes in the amazonian region, including increased frequency of extreme climatic events, increased average temperatures, increased atmospheric CO2 and reduced rainfall intensity. Understanding tree growth response to climate is important because wood production is the main way carbon enters the forest ecosystem. The response of tropical tree growth to changing climate could drive a change in the direction of the flux from terrestrial ecosystems to the atmosphere. The last 20 years has seen a substantial increase in the number of publications with a focus on the effects of climate on tropical tree growth. Citation reports extracted from the Web of Science with the keywords 'climate', 'tropical forest', 'growth' and 'trees' found only 15 articles in 2000 and more than 70 in 2011. These articles are based mostly on modelling approaches combining tree growth and one or more climate indices. We review the different approaches used in order to, (i) identify gaps in current research, (ii) determine which climate index is the most relevant for a range of temporal and spatial scales and (iii) establish which climate indices are the most appropriate to study tropical tree growth in regards to the climate output of the IPCC scenarios.

Towards a unified characterization of phenological phases: fluctuations and correlations with temperature

Phenological timing -- i.e. the course of annually recurring development stages in nature -- is of particular interest since it can be understood as a proxy for the climate at a specific region; moreover changes in the so called phenological phases can be a direct consequence of climate change. We analyze records of botanical phenology and study their fluctuations which we find to depend on the seasons. In contrast to previous studies, where typically trends in the phenology of individual species are estimated, we consider the ensemble of all available phases and propose a phenological index that characterizes the influence of climate on the multitude of botanical species.Comment: 16 pages, 6 figures, appendix with 1 table; accepted for Physica
