Organizational initiatives for addressing climate change challenge -Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008

Climate change, resulting from global warming, has been moving to the main stream administrative and political initiatives in the last two decades. To address humanity’s biggest test, several organisations, institutions, panels, networks, universities and non-governmental organisations have turned the spotlight on the man made problem of climate change

Critical Thinking

Women are the foundation of society and breeders and teachers of the next generation. We comprise half of the population of the world, and thus should be equals in every step with men. In order to do so, logical, analytical thinking (devoid of emotional drivers and personal pride) is crucial for a society to function healthily. To incline women to realize the benefits being more curious and analytical about the decisions that is made for them by men in their lives. If women remain as a mass of silent sufferers instead of individual thinkers who challenge status quo, then lack of societal respect for and protection of women’s personal decision-making in regard to unwanted pregnancies, style of dress, a their right to choose their partners, etc. will continue. Here lies the relevance of critical thinking that will allow them to become the experts in all fields

Climate change impacts : Implications on marine resources and resource users

The warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. The Earth’s average surface temperature has risen by 0.76° C since 1850. Most of the warming that has occurred over the last 50 years is very likely to have been caused by human activities. In its Fourth Assessment Report projects that, without further action to reduce greenhouse gas emissions, the global average surface temperature is likely to rise by a further 1.8-4.0°C this century, and by up to 6.4°C in the worst case scenario. Even the lower end of this range would take the temperature increase since pre-industrial times above 2°C – the threshold beyond which irreversible and possibly catastrophic changes become far more likely

Puducherry mangroves under sewage pollution threat need conservation

Indian mangroves have a rich diversity of soil-dwelling organisms which include micro, meio and macro forms. Mangrove ecosystem provides an ideal nursery and breeding ground for most of the marine and brackish water fish and shellfish. India has only 2.66% of the world’s mangroves1, covering an estimated area of 4827 sq. km. The present study area lies within the margins of lat. 11°90′107″– 11°90′703″N and long. 79°80′547″– 79°81′851″E. Mangrove exists as fringing vegetation over 168 ha distributed along the sides of Ariankuppam estuary, which empties into the Bay of Bengal (Coromandal coast) at Veerampatinam on the southeastern coast of Indi

Appraisal of the socio-economic status of fishers among the different sectors in Kerala, south-west coast of India

The present study assessed the levels of literacy, health, income and livelihood security of fisher households across different fisheries sectors in Kerala. Primary data collected across 567 households during January to December, 2011were used for the study. The general trend in Kerala shows that majority of the fisherfolk were of the age group 36-55, with a small family norm and high literacy rate. The marine capture sector has the highest annual income in comparison with other sectors but registered higher indebtedness. While the highest income from non-fishery activity was from labour  followed by business, other sectors and agriculture. The study revealed that the fishers spend their major share of income towards food expenditure. Inspite of the income from various sources, majority of the households are swamped with debts which make them to rely on private money lenders for sustaining their living standards. The study is a cross sectoral analysis of the fisher households in Kerala and provides a base for implementing developmental plans for the betterment of the fishing community

El Nino Southern Oscillation (ENSO) impact on tuna fisheries in Indian Ocean

El Nino Southern Oscillation (ENSO) is an important driver of interannual variations in climate and ecosystem productivity in tropical regions. However, detailed information about this important phenomenon of the Indian Ocean is scarce. Consequently, the objective of this study is to improve understanding of the impact of warm event El Nino and cool event La Nina on annual tuna landings from the Indian Ocean from 1980 to 2010. In this study, maximum tuna landings were recorded during a weak El Nino year (1456054 t in 2006) and during a weak La Nina year (1243562 t in 2000), although the lowest tuna catch was followed during the strong El Nino year (1204119 t in 2009) and during a strong La Nina year (706546 t in 1988). Validation of predicted tuna landings and SST were showing a significant positive correlation (p < 0.01) was observed all the major tuna species except Southern Bluefin Tuna. Whereas the other relationships such as sea level pressure, Wind actions; Zonal Wind (U), Meridonial Wind (V), and Scalar Wind (W) are less well-defined. In contrast with principal component analysis we find that Principal Components 1 explains 75.5% of the total variance and suggest that sea surface temperature plays a major role in determining tuna availability in the region especially during warm event El Nino years; landings in Indian Ocean tend to be optimum SST 25 to 26°C in ENSO event. Our results confirm the ENSO impact on climate, tuna abundance and production in the Indian Ocean. However, among the oceanic variables SST explained the highest deviance in generalized additive models and therefore considered the best habitat predictor in the Indian Ocean followed by sea level pressure and Winds (U, V, W)
