ProjectPromote Scaling-Up of Innovative Rice-Fish Farming and Climate-Resilient Tilapia Pond Culture Practices for Blue Growth in Asia - TCP/RAS/3603 2020
Also available in:
No results found.In the past two decades, Asia has been responsible forapproximately 90 percent of global aquacultureproduction. Global and regional demand for fish isexpected to increase significantly in coming decades as aresult of population increase and potential changes inpeople’s dietary habits. Further growth of aquaculture inAsia is crucial to meeting this demand. It has beenprojected that Asian aquaculture production will need toincrease by 60 percent by 2030.In order to support the sustainable growth of aquaculturein the Asia and Pacific Region, FAO began to implement aRegional Initiative on Sustainable Intensification ofAquaculture for Blue Growth in early 2014. Addressingtwo major challenges faced by the aquaculture industry inthe region - the need to improve the use of naturalresources while increasing the productivity and resilienceof small farmers in the context of climate change andother natural and socioeconomic uncertainties - theinitiative supported field projects in the participatingcountries to promote innovative aquaculture farmingpractices, including demonstration projects of rice-fishfarming in Indonesia and rice-shrimp farming in Viet Nam,and a country project to build the resilience of tilapiafarmers in the Philippines. All the field projectsimplemented under the initiative have achievedremarkable results in terms of upgrading farming practicesand generating knowledge and experiences that can beshared with other countries in the region.The current project was formulated to support the scaling-up of the innovative aquaculture farming systems andpractices proven to be successful under the regionalinitiative. Its aim was to disseminate and demonstrateinnovative rice-fish farming and climate-resilient tilapiapond culture practices in the five focus countries and tostrengthen human capacity and the enabling environmentfor the scaling-up -
Book (stand-alone)Improving the performance of tilapia farming under climate variation: perspective from bioeconomic modelling
FAO Fisheries and Aquaculture Technical Paper No. 608
2018Also available in:
No results found.Tilapia is the world’s most popular aquaculture species, farmed mostly in earthen ponds. Experience in China, the largest tilapia farming country, is used to develop and calibrate a bioeconomic model of intensive tilapia pond culture. The model is used to simulate the impacts of climate, technical and/or economic factors on farming performance and examines the performance of various farming arrangements under different conditions. The simulation results indicate that: (i) an increase in feed price, an increase in mortality, or a decrease in fish price significantly reduces profitability, whereas an increase in the cost of seed, labour, rent, electricity or water management has smaller impacts on profitability; (ii) considering the impact of water temperature on fish growth, the profitability of a production cycle starting at the optimum timing may be twice as high as one starting at the worst possible time; (iii) farming arrangements that maximize the profit of individual fish crops may not maximize overall profitability because of path dependency of farming performance; (iv) optimal farming arrangements that maximize overall profitability can significantly improve economic performance; (v) given no price discrepancy against small-size fish, harvesting at about 300 g in two-year-five-crop arrangements could increase overall enterprise profitability by up to 50 percent compared with harvesting at > 500 g in one-year-two-crop arrangements; and (vi) a two-tier farming system that separates nursing and outgrowing ponds could allow one-year-three-crop arrangements that enhance profitability by up to nearly 90 percent compared with the one-year-two-crop arrangements. With more refined information on fish growth under different farming conditions, the model could become a decision-making tool to help farmers design optimal farming arrangements. -
DocumentRice-fish farming: a development lever for smallholder farming in Madagascar 2014
Also available in:
Madagascar is one of the poorest countries in the world and one of the top three countries considered the most vulnerable to the effects of climate change exacerbated by deforestation, natural disasters, chronic poverty, a high dependency on agriculture and a lack of adaptability. Madagascar ranks 154th (out of 185 countries) in the Human Development Index (UNDP 2015), having dropped 19 places between 2010 and 2014 reflecting a difficult internal economic, political and social situation. In fact , according to international thresholds, the poverty rate is 91 per cent (INSTAT/ENSOMD 2012- 2013). According to the national poverty line, 71.5 per cent of Malagasy people are poor and 52.7 per cent are extremely poor, meaning that their resources do not allow them to meet their basic food needs. Poverty in Madagascar is predominantly a rural phenomenon mainly affecting farmers, given that almost 77 per cent of the working population is involved in agriculture. Poverty also comes with another reality, that of the prominence of malnutrition. More than 40 per cent of infant mortality is caused by malnutrition; 47.3 per cent of children under the age of five suffer from acute malnutrition and the overall rate of acute malnutrition is 8.3 per cent (INSTAT/ENSOMD 2012-2013). Chronic malnutrition in children results in irreversible delays in physical and cognitive growth that are part of the vicious circle of poverty. Madagascar lost 14.5 per cent of its gross national product in 2013 beca use of malnutrition, amounting to 1,533.6 million US dollars and 66 per cent of working-age adults (15-64 years) suffered from stunting as a child, representing 8,287,508 people who were unable to reach their true potential1. In response to this challenge a project was launched in 2014 aimed at accelerating the spread of carp aquaculture2 in the rice fields of Madagascar’s Highlands (rice-fish culture) in the regions of Haute Matsiatra, Vakinankaratra, Itasy and Amoron’i Mania. The immediate obj ective of this project is to develop an innovative, inexpensive and far-reaching training circuit in rural areas. Secondary objectives are to both reduce household poverty by providing a source of income and contributing to the reduction of malnutrition through a targeted increase in the availability and consumption of fish. Rice-fish integration makes it possible to optimize the use of land and water resources, in addition to other available facilities, with little investment by combining the p roduction of plant and animal products. Ricefish farming can increase rice yields by 10 to 30 per cent and produce fish with an average yield of 205 kg/ha. In Madagascar, the actual production of fish in rice fields is an estimated 3-5,000 MT per year, but this could go up to 30 to 50,000 MT per year in 30 years with the expected impacts of combatting malnutrition and rural poverty.
