The main sources of livelihood before the tsunami were small businesses, informal day labor, government civil service, fisheries, and rice agriculture. Most of the neighborhoods/villages along the coast engaged in aquaculture. Rice fields ringed the city and extended far to the south. The tsunami penetrated up to 2 km inland, causing almost complete destruction to the built environment, massive loss of life, and significant alteration to the natural environment. All aquaculture features and large tracts of rice fields were damaged. Between 2005 and 2008, 65 registered livelihood projects spent just over 29 million USD in tsunami-affected villages in Zone 1 (Supplementary Table 1). Seven projects spent almost 2 million USD rehabilitating agriculture. These supported cash-for-work to clear agricultural lands, training and capacity building programs, and provision of equipment, seeds, fencing and fertilizer e most of which was dedicated for rice cultivation. Seventeen projects spent over 5 million USD rehabilitating the fishing industry (Supplementary Table 1). This was spilt between providing equipment such as boats and nets for fishermen, building fish processing and selling facilities, and clearing and repairing damaged aquaculture infrastructure. 4 Half the livelihood aid in Zone 1 was used for large economic infrastructure projects such as markets, ports, and manufacturing & processing facilities. 2.2. Zone 2 The villages in Zone 2 occupy a narrow coastal plain, ranging from 100 to 3000 m wide-abutting heavily forested mountains. Zone 2 is predominantly rural, with respondents stating that up to 90% of pre-tsunami livelihoods involved rice cultivation, tree-crop plantations, fishing and aquaculture. Due to the separatist conflict, and poor transportation infrastructure, Zone 2 villages had long been isolated and disconnected from Banda Aceh. All inhabited areas were inundated by the tsunami, causing heavy damage to rice fields and aquaculture, and major loss of life. Between 2005 and 2008 17 registered livelihood rehabilitation projects were carried out by donors in Zone 2, totaling more than 6.6 million USD (Supplementary Table 2). Seventy six percent of the aid was allocated for agricultural rehabilitation (approximately 5 million USD), most of which was for rice cultivation. Aid supported cash-for-work to clear rice fields, rebuild rice field and irrigation infrastructure, distribution of inputs such as seeds, fertilizer, fencing and farming equipment, and capacity building. Zone 2 received very little dedicated aid for rehabilitating aquaculture. 2.3. Zone 3 Zone 3 consists of a shallow coastal plain abutting junglecovered mountains, often no more than 1500 m wide. As this area serves as the administrative center of the Aceh Jaya district, a significant number of the residents within tsunami-affected villages were government civil servants or manage small businesses. Subsistence livelihoods were a secondary part of the overall economic strategy. The tsunami destroyed the entire built environment, caused massive loss of life, and damaged most rice fields. There was no aquaculture in the zone before the tsunami. Between 2005 and 2008, 16 registered livelihood projects were carried out by donors in Zone 3 villages, totaling more than 5.7 million USD (Supplementary Table 3). Slightly more than 60% of the funding (3.5 million USD) was allocated for agriculture rehabilitation, mostly for rice cultivation. These projects provided funding to clear debris and rebuild basic agricultural infrastructure (mainly through cash-for-work schemes), provision of agricultural inputs such as seeds, fertilizer, and equipment, and training/capacity building. The rest of the livelihood aid went towards infrastructure and small business support programs. staff, looking at the sustainability of aid, and transformation across seven sectors: housing, demographics, livelihoods, disaster risk reduction, governance, relocation, and gender. The project conducted in-depth fieldwork in over 130 tsunami affected villages and neighborhoods, some of which are featured in this paper. 6 The scope of the analysis was in part influenced by the availability of satellite images for the 3 study areas. It was not possible to obtain images for all three zones at exactly the same times, which limits comparison between the sectors, but does not diminish the overall patterns within each sector.

The forest has been deforested and converted to agricultural lands. Hence, the objective of the present study was to evaluate the community structure of macrozoobenthos in Tripa peat swamp. Five sampling locations were determinated using purposive random sampling which was focussed in the main river mouths of Tripa, Suak Tripa, Seuneam, Batee and Taduu Rivers. The sediment was collected in three plots (1m x 1m) at every sampling location. The results showed that, there were 34 species of macrozoobenthos recorded during the sampling, it is belonging to 4 classes; Gastropoda, Bivalvia, Crustacea and Insecta. The species richness were ranged between 1.12 to 1.58, indicates low category. The diversity and evenness indices were ranged between 0.62 to 2.44 and 0.19 to 0.73, respectively; indicates low to moderate values. It was concluded that the macrozoobenthos community of Rawa Tripa was in...

We assess the extent to which post-tsunami aid in Aceh helped beneficiaries to stabilize and restore their pre-disaster livelihoods, and/or develop new livelihoods. We draw upon qualitative data captured in 183 in-depth interviews and 38 focus group discussions involving village leaders, livelihood aid participants, and NGO workers. Our results show that livelihood assistance helped people stabilize their household finances and partially restore their pre-disaster livelihoods. Furthermore, we found that aid programs were able to help some people without pre-disaster livelihood experience to participate in part-time, ad hoc work. However, aid packages were generally not able to support the development of fulltime, sustainable new livelihoods for people lacking pre-disaster training and experience. Our data suggests that it is difficult to conduct efficient and sustainable livelihood development initiatives within the time pressures and current institutional approaches to large-scale post-disaster reconstruction.

We supplement this with qualitative data to illustrate the post-disaster challenges faced by residents, and the extent to which coastal communities have adapted to post-tsunami realities. Our analysis shows that the rehabilitation of rice cultivation and aquaculture in areas inundated by the tsunami has been limited by extensive degradation of land, diversion of labor by tsunami mortality and transition to alternative livelihoods, and re-purposing of rice fields for residential use during the reconstruction phase. This is especially prominent in areas where subsistence activities are not the primary source of livelihood. The Aceh case study shows that social, economic, and environmental factors can be stronger determinants of how coastal livelihoods rebound and change following destructive inundation events than livelihood rehabilitation aid. Additionally, our case study suggests the human impact of coastal hazards can be felt outside the physical extent of inundation.

The objective of this study was to develop an inventory of the fish fauna, evaluate the spatial variation in assemblage structure, document alien species, and quantify the economic value of fish species found from the area. Fish assemblages from the main rivers and tributaries of TPSF were sampled on May to June 2013. A total of 764 individuals were sampled during the survey, constituting 34 families, 47 genera, and 73 species where 46 species are categorized as fish consumption, 17 have potential for aquaculture, and 10 species have potential for ornamental, and three are non native. Cyprinidae is the predominant fish family within the TPSF. Fish assemblages were generally characterized by small population size for each species and low similarity among sites, reflecting the distinctive nature of ...
