The Impact of Climate Change on Mud crab Fishery and Fattening to the Communities Livelihood in Pangani and Rufiji Estuaries in Tanzania

Abstract: 
The mud crab (Scylla serrata) is a big portunid crab that lives on soft muddy bottoms association with mangrove-lined estuaries in the Indo-West Pacific. They have fast growth rates, early maturity, wide distribution and high fecundity. Mangrove associated fauna would be affected directly by change in climatic condition variables. This study, just initiated, is assessing the contribution of mud crab fattening and fishery to the communities’ livelihoods. Findings will help to establish whether mud crab farming is a plausible adaptation strategy for mitigating impact of climate change to coastal communities in Tanzania.
Le crabe de palétuviers (Scylla serrata) est un grand crabe de la famille des Portunidae qui vit sur une molle association des fonds boueux aux estuaires bordés de mangroves dans le Pacifique Indo-Ouest. Ils ont des taux de croissance rapide, une maturité précoce, une large distribution et une fécondité élevée. La faune associée à la mangrove serait directement affectée par les changements dans les variables de condition climatique. Cette étude, juste initiée, évalue la contribution de l’engraissement des crabes de palétuvier et celle de la pêche aux moyens de subsistance des communautés. Les résultats permettront de conclure si l’élevage des crabes de palétuvier est une stratégie d’adaptation plausible pour atténuer l’impact du changement climatique pour les communautés côtières de la Tanzanie.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Risk and Vulnerability
