Autonomous adaptation to climate change by shrimp and catfish farmers in Vietnam’s Mekong River delta

The Mekong River delta of Vietnam supports a thriving aquaculture industry but is exposed to the impacts of climate change. In particular, sea level rise and attendant increased flooding (both coastal and riverine) and coastal salinity intrusion threaten the long-term viability of this important industry. This working paper summarizes an analysis of the economics of aquaculture adaptation in the delta, focusing on the grow-out of two exported aquaculture species—the freshwater striped catfish and the brackish-water tiger shrimp. The analysis was conducted for four pond-based production systems: catfish in the inland and coastal provinces and improved extensive and semi-intensive/intensive shrimp culture.

Movimentos sociais como produtores de conhecimento: a Soberania Alimentar no Movimento de Pequenos Agricultores (MPA).

A presente tese adota uma perspectiva cognitiva e epistêmica para o estudo dos movimentos sociais, tendo como objeto de estudo a Soberania Alimentar no Movimento dos Pequenos Agricultores: MPA. Defendemos a ideia que, através de sua atuação prática e discursiva, os movimentos sociais estão travando uma luta que, além de política e cultural, é também cognitiva e epistêmica e que essa dinâmica social é geradora de novas formas de conhecimento, como a Soberania Alimentar. Neste trabalho, a Soberania Alimentar é entendida como um programa social de conhecimento que vem sendo desenvolvido pela rede transnacional de movimentos sociais Via Campesina e as suas organizações constituintes (dentre as quais o MPA), articulados com entidades parceiras em redes de solidariedade transnacionais e transculturais e em oposição aos seus adversários, em relação a distintos contextos e escalas de ação. Apoiados nessa ideia e na perspectiva adotada, pretendemos revelar aspectos da multidimensionalidade e da multiespacialidade da dinâmica constitutiva da Soberania Alimentar, a partir do estudo das correlações entre o local e o global, o particular e o geral e as dimensões prática e intelectual da produção de conhecimento por movimentos sociais.

A Região Noroeste Fluminense e o Projeto Rio Rural: Tendências e problemas da agricultura familiar

O objetivo deste trabalho é analisar o processo de regionalização do noroeste fluminense através das ações verticalidade sob controle do Estado. Verifica-se especificamente, o posicionamento da sociedade civil organizada e as relações de poder envolvidas diante de tais inferencias racionalizadoras do espaço, e de que forma esse posicionamento pode redimencionar o ordenamento espacial que se impõe através das hegemonias de poder. Entre as abordagens ao tema, o trabalho considera, primeiramente, o processo de regionalização do noroeste fluminense por meio de relações socioespaciais pretéritas a fundação da região enquanto unidade administrativa. Para além das atuais fronteiras da região em questão, o trabalho destaca o controle do Estado pelas frentes catequizadoras e colonizadoras, sobre o território dos Puri, Coroado e Coropó. A segunda intermediação do trabalho ao tema diz respeito à ação de atores locais, ligados principalmente a grandes pecuaristas, na luta por autonomia econômica em relação a Campos dos Goytacazes; que em suas relações de poder com o Estado do Rio de Janeiro desencadeiam a instituição político-administrativa do noroeste fluminense. Sucessivamente o trabalho grifa a atribuição de características regionais a área de estudo como: pobreza rural e representatividade da agricultura familiar, relacionadas a ações de intelectuais orgânicos locais para direcionar verbas do Governo Federal ao setor agropecuário. A terceira parte do trabalho incorpora ao tema a descentralização da gestão municipal/regional por parte de políticas de planejamento territorial como o Rio Rural. Visto que ações de verticalidade do Governo do Estado do Rio de Janeiro, através do Projeto Rio Rural, intervém no ordenamento sócio-econômico-espacial da região principalmente através do modo de produção da agricultura familiar, a problemática se estenderia ao posicionamento político dessa categoria, enquanto sociedade civil organizada; para consideração final das tendências estabelecidas pela agricultura familiar ao ordenamento espacial regional

Informal fish retailing in rural Egypt: Opportunities to enhance income and work conditions for women and men

Poor rural consumers benefit from Egypt’s aquaculture sector through access to small and medium-sized farmed tilapia sold by informal fish retailers, many of whom are women. In fact, informal fish retail is the main, if not only, segment of the farmed fish value chain where women are found. This report aims to inform current and future strategies to improve conditions in informal fish retail by understanding in more depth the similarities and differences in employment quality and outcomes across different fish retailers. It is particularly focused on identifying whether and how gender inequality influences different dimensions of the work, and whether women and men have similar outcomes and employment conditions. This knowledge will help to design interventions to overcome gender-based constraints, as well as approaches that address shared obstacles and include both women and men in gender-responsive ways to ensure that all of those involved in the sector benefit.

Foods and diets of communities involved in inland aquaculture in Malaita Province, Solomon Islands

Solomon Islands has a population of just over half a million people, most of whom are rural-based subsistence farmers and fishers who rely heavily on fish as their main animal-source food and for income. The nation is one of the Pacific Island Counties and Territories; future shortfalls in fish production are projected to be serious, and government policy identifies inland aquaculture development as one of the options to meet future demand for fish. In Solomon Islands, inland aquaculture has also been identified as a way to improve ood and nutrition security for people with poor access to marine fish. This report undertaken by a Worldfish study under the CGIAR Research Program on Aquatic Agricultural Systems explores the e potential role of land-based aquaculture of Mozambique tilapia in Solomon Islands as it relates to household food and nutrition security. This nutrition survey aimed to benchmark the foods and diets of households newly involved in small homestead tilapia ponds and their neighboring households in the central region of Malaita, the most populous island of all the provinces in Solomon Islands. Focus group discussions and semistructured interviews were employed in 10 communities (five inland and five coastal), four clinics, and five schools.

Production and economic return in pangasiid catfish (Pangasius hypophthalmus) monoculture and polyculture with silver carp (Hypophthalmichthys molitrix) in farmers' ponds

The production of fish and net economic return in pangasiid catfish (Pangasius hypophthalmus) monoculture and polyculture with silver carp (Hypophthalmichthys molitrix) in farmers' ponds were assessed. The experiment was arranged in three treatments each with three replications. The ponds were stocked with 30,000 fishes per hectare. In treatment 1 (T1) pangasiid catfish only, in treatment 2 (T2) pangasiid catfish and silver carp at the ratio of 1:1, and in treatment 3 (T3) pangasiid catfish and silver carp at the ratio of 2:1 were stocked. At harvest, production of fish was found significantly (p<0.05) different among the treatments, highest in T1 and lowest in T2. Though the total biomass production and total economic return was significantly highest in T1 than in T2 and T3, the net economic return was lowest because of the required highest input costs especially for supplemental feed and fingerlings, resulted the highest cost per unit yield (CPY in Tk/kg) in T1. Highest cost for supplemental feed required in T1 was due to highest quantity of feed required for the highest number of pangasiid catfish stocked in that treatment. The findings of the present study suggest that though monoculture of pangasiid catfish give higher fish biomass production but polyculture with silver carp is environmentally good and economically profitable.

Sustainable livelihood approach of prawn production and marketing systems in Mymensingh, Bangladesh

An investigation was carried out in Phulpur upazila, Mymensingh to examine the current production practices of freshwater giant prawn, Macrobrachium rosenbergii and its marketing systems with sustainable livelihood approach. The livelihoods of a considerable number of rural poor are associated with prawn production in Phulpur upazila. Based on a sample of 50 farmers, about 94% farmers were found to culture prawn with fish in their ponds. Only 4% and 2% farmers were found to culture prawn-fish-dike crops and only prawn respectively. Prawn marketing is almost exclusively a preserve of the private sector where the livelihoods of a large number of people are associated with its distribution and marketing systems. The market chain from producers to consumers passes through a number of intermediaries. About 40% of the produced prawns are exported and the rest 60% are sold to local markets. The price of prawn depends on quality, size and weight. The average farm-gate price of prawn varied from Tk. 110 to 160/kg, whereas it's [sic] market price varied from Tk. 150 to 350/kg. Most of the farmers and traders have improved their socio-economic conditions through prawn farming and marketing activities. However, concerns arise about the long-term sustainability of prawn farming and marketing systems due to lack of technical knowledge of prawn farming, poor road and transport facilities, higher transport cost, poor supply of ice, lack of cash and credit facilities. It is therefore essential to provide institutional and organizational support and credit facilities for sustainable prawn production and marketing systems.

Factors affecting the adoption of aquaculture technologies by the farmers

Purpose of the study was to ascertain the extent of adoption of aquaculture technologies by the farmers as well as constraints faced by them in adopting the aquaculture technologies. The study also explored its relationships with the selected characteristics of the farmers. In addition, an attempt was also made to determine some selected attributes of the technologies and their relationships with the adoption by the farmers. The study was conducted with the farmers of 10 upazilas of greater Mymensingh district who were the beneficiaries of three NGOs viz. SARA, ORD, and GRAMAUS. There were 351,241 and 249 beneficiaries under SARA, ORD and GRAMAUS, respectively who adopted the aquaculture technologies under DSAP. About 25% farmers from each of the three NGOs were selected for the study. The total sample size was 212. Pre-designed and pre-tested interview schedules were used for collecting data from the farmers. Field data were collected from the farmers during August-September, 2004. Pearson product moment correlation co-efficient were computed in order to explore the relationships of the selected characteristics of the farmers as well as selected attributes of technology with the adoption of aquaculture technologies by the farmers. The same statistical test was used to determine the relationships between the selected characteristics of the farmers and their constraints in adopting the aquaculture technologies.

A study on rural women's empowerment through participation in aquaculture

The study was undertaken to understand the rural women's (i) extent of participation in some selected aquaculture practices and (ii) extent of empowerment through participation in aquaculture program. Data were collected from 200 selected rural women of two districts - Sherpur and Kishoreganj. Each of the families where the selected rural women who were involved in aquaculture under the supervision of two partner NGOs of DSAP, namely- Foundation for Human Development (FHD) and Center for Rural and Environmental Development (CRED). Both conventional and participatory methods of data collection were employed where structured questionnaire and Focus Group Discussion (FGD) were used as the tools. The data collection procedure took five-months spanning from September 2004 to January 2005. Appropriate scales were developed and used in order to determine the focus variables of the study, while most analyses regarding women empowerment were done using 'before' and 'after' method. Empowerment of women was measured by five dimensions such as decision making ability, spending ability, social participation, cosmopoliteness, access to assets and resources. The ten selected aquaculture practices were: fish feeding, eradication of aquatic vegetation from fish pond, disease detection, application of fertilizer, liming, harvesting of fry and fish, fish stock management, pond excavation, use of insecticides, and sale of fry and fish. The study also aimed at determining some selected characteristics of rural women and determining relationship between their extent of empowerment and the selected characteristics. The characteristics of rural women included: age, personal education, average family education, family size, family farm size, area under aquaculture, extension media exposure, training exposure, knowledge in aquaculture, and family income. The findings revealed an overall low level of participation by rural women in aquaculture activities. However, significant level of improvement was identified regarding overall status of empowerment during the course of participation in aquaculture program under DSAP.

Production of freshwater giant prawn using over-wintered juveniles for enhancement of farm income and reduction of rural poverty in Bangladesh

Freshwater giant prawn, Macrobrachium rosenbergii fry produced during late season can not withstand low temperature thus the prawn culture programme during winter is hampered. To overcome this problem, late season (August-September) prawn juveniles (0.9-6.8 g) were stocked at a density of 1.43 to 3.57/square meter in 350-476 square-meter ponds in Pabna and Mymensingh districts during October 2000 and cultured till May 2001. Monthly average water temperature during the winter months (December-February) varied from 16 to 22 °C and gradually increased to 32 °C in May. The prawn fry showed fast growth rate and attained an average weight of 60-70 g within eight months including three winter months. Growth compensation was observed during summer months. Survival rate was 60-79%. After extrapolation of the present growth rate more than 1,600 kg/ha production can be achieved in better-managed ponds. Extrapolated cost of production was Tk. 268,000 and 200,000 Tk./ha in two best ponds, sale value was Tk. 644,9146 [sic] and 528,466 and gross profit was Tk. 376,000-410,000, suggesting a higher economic feasibility of farming freshwater prawn with over-wintered juveniles.

Poor fish farmers' accessibility to credits: A review

Fisheries sector contributes about 5.3% to GDP and about 6% of the export earnings of Bangladesh. There are about 4.1 million ha of inland water bodies in Bangladesh. However, over last two decades the catch from inland capture fishery has decreased due to filling of wet lands and other anthropogenic reasons. Accordingly, the production of inland fish has decreased not only for the decrease of water bodies but also due to irrational catch of fish fries, brood fishes and use of current nets for fishing. Significant responses from the fisheries entrepreneurs have not been received for the small loan scheme of the Bangladesh Bank. The bank could not disburse more than Tk. 500 million under the scheme. The total revolving credit under the scheme was Tk. 1,000 million with the assistance from the World Bank. The business houses having fixed assets of value not more than Tk. 10 million will be eligible to borrow from this fund. About Tk. 0.2-5.0 million can be borrowed as term loan and working capital from Bangladesh Bank through commercial banks. The loan was given to the commercial banks at 5% interest (bank rate) and the commercial banks shall also bridge finance to the entrepreneurs at a lower rate of interest. Working capital time limit is for a maximum of 1 year with half yearly rest, mid-term loan maximum of 3 years in 5 installments and with 6 months grace period and long-term loan maximum of 5 years in 9 installments with 6 months grace period.
