## 1 Introduction

Extensive fish farming has proven to be an advantage for small-scale farms. Requiring little cash, this activity better valorizes the existing production factors and agricultural byproducts. It also reduces the food expenses, increases the farm income and improves the diet of rural households. In Africa, the economic impact of this fish farming system in rural area tends to be under-estimated and insufficiently taken into account by the national development plans where financial and human resources are predominantly targeted at the medium or large-scale commercial aquaculture. Without questioning these choices, a more balanced perspective is needed.

The main objective of the RéSyPiEx project is to make policy-makers aware that the "traditional" or extensive systems can be also driven by the market. Supported by PARRAF (Programme Supporting Research Networks in Africa), this network of various West and Central African research institutions involved in aquaculture has been initiated in 2011 by the research project "Ecological intensification of extensive family fish farming systems in West and Central Africa by the analysis of the innovation processes - extensive fish farming systems" (SyPiEx) - funded by the CORAF / WECARD. The research studies have been anchored in the development through NGO partnerships, including the APDRA - Pisciculture paysanne NGO. This presentation outlines the activities conducted by the research network and the stakes for the development of rural fish farming

## 2 Activities

The network teams involved in the network have strengthened their AIR4D capacity. They conducted a first literature review of previous and ongoing work to analyze the social, environmental and economic impacts of family fish farming systems in Western and Central Africa. The network also promoted the implementation of regional research and education collaborative programmes, leading to students, researchers and teachers exchanges.

### Better describe to better promote the SyPiEx

The classic fish culture introduced in sub-Saharan Africa for decades has difficulty develop despite the efforts of the technical and financial partners on the continent. However, systems worn by family farms adopted by most local producers play an important role in the diversification of production and provide additional income to farmers. However, this form of farming in rural areas and in particular, the extensive aquaculture systems are poorly described. The regional literature reviews on SyPiEx in each country (Table 1), will help to publish policy notes in order to facilitate decision making in the fields of SyPiEx in West Africa and Central.

## Research and development in extensive fish farming systems: AIR4D approach

Diversity of choices and practices both in terms of the organization, breeding systems and their integration modalities have enabled the development of spontaneous innovation by fish farmers. Technical choices are made by producers from innovations that have demonstrated their efficiency in the local context. On this basis, the actual constraints to overcome to successfully lead intensification are identified and assumptions are developed with producers and all stakeholders in the innovation platform. The prioritization of constraints led to the identification three major researches related to (1): Access to property in the context of SyPiEx; (2): Farm and economic optimization of SyPiEx (3): Optimized fingerlings production in SyPiEx.

## Promote the training of students through south-south mobility

Students involved in the different motilities are supervised by supervisors from different teams (for sending and receiving) thus improving the level of training of students and facilitates research partnerships between different laboratories. During 2014, 10 students involved in the network teams have benefited from mobility grants for realization of courses related to one of three cross-cutting themes identified in West Africa and Central Regions (Table 2).

**1 Introduction**

For more than a decade, integration of extensive fish farming inside smallholder's farming has been noticed as an alternative way to promote aquaculture development. Inside the plantation economies area of Western Africa, various developments have occurred. The present study analyses and compares situations from Côte d'Ivoire, Cameroon and Benin, thanks to a regional project (SYPIEX) through field data collected in those countries during 2013.

**2 Materials and Methods**

132 inquiries of fish farming producers were conducted in Central-West and South-West of Côte d'Ivoire and 125 in Central Region and Eastern Region of Cameroon in order to get an up to date description of rough technical and socio-economic characteristics. Inquiries and Value Chain Analyze were carried out in the three countries.

**3 Results**

The collected data show an interesting convergence between the two fish farming developments. The declared average ponds area is 0,67 ha for one fish farmer in Cameroon and 1,12 ha in Côte d'Ivoire, that illustrate the central function of the dam-pond which make the management of large areas easy, often associated with little derivating ponds. The pond average area is 0,30 ha in Cameroon and 0,28 ha in Côte d'Ivoire (RCI). Fish farmers combine production of various ponds: 3,65 ponds in RCI and 2,35 ponds in Cameroon. Polyculture based on *Oreochromis niloticus* is the most common practice and for the second species used, *Heterotis*, is the most favourite one. This fish farming has first a commercial function and a significant part of the producers reports fish farming as their main activity: in Côte d'Ivoire 23%, in Cameroon 24% (and in this country for Eastern and Central Region, respectively 32% and 0%). Fish farmers are mostly farmers (92% in RCI, 61% in Cameroon). Logically the production requires mostly family workforce and the ponds have been essentially built with the household's resources. Those two characters indicate the reality of the integration of this type of fish farming that has most often an important place in the farming system. Education level fluctuates, it can be noticed that in RCI, most of the fish farmers who manage the fish farms are illiterate (63%), in Cameroon, 75% stopped their education training before the A levels. Inquiries point out a high percentage of fish farmers belonging to local professional organizations. The rate of women as fish farm managers is low, but they are involved in the fish management and often in charge of the sales. This type of fish farming concerns most of the ethnic or religious components of the local population. The average number of years of fish farming experience shows its dynamic: it is 10,17 in RCI, 10,8 in Cameroon; however this figure hides a significant difference (p < 0,05) inside this country, 11,4 and 6,5 for respectively the Eastern and the Central Regions ; this indicates different maturity and also a dynamism with new settings. Compilation of technical criteria (yearly production, yield) is always risky with inquiries. The quoted « yearly production » has respectively an average of 552 kg and of 353 kg in RCI and Cameroon. However, strong contradictions subsist. The declared fish breeding practices were collected and are summarized in table 1, below. The value chain analysis indicates that a large share of the added value is created in the fish production step, even if data vary and a described tendency is to supply stocking fingerlings inside local networks which is the best economic answer facing the potential high cost of the fish seeds. The fish produced is first sold on local markets, prices fluctuate around 1000 F CFA/kg in Ivory Coast to 1500 F CFA in Cameroon. When urban markets are accessible, farmed fish is preferred to other fish substitutes because of its quality. In Côte d'Ivoire and Cameroon, the added value generated by fish processor nearly doubles the one realized by the producers.

**4 Discussion**

Firstly, this fish farming type has become strongly settled for more than a decade and shows a dynamic. Surprisingly,
this type cuts loose some clichés broadly admitted in Africa: small ponds (most often < 400 m<fnref n="2" />), fish density above 2,

small fish produced, the key need of the catfish etc. It is not confronted with a question of bad fish growth, table 1 indicates from the fish farmers' declarations that the *Oreochromis* daily growth exceeds 1g/j thanks to the use of a police fish or their natural profusion (for example, *Parachanna obscura* in the Eastern Region). Fish polyculture presents a sturdy model although it is not always understood like in the Eastern Region and with a size of the ponds similar to that of the traditional Chinese one. That underlines the need to consider that this type of fish farming generates a specific alternative path with its own research-development questioning depending of its development. Secondly, this kind of fish farming is oriented by commercial purposes. Spontaneously, products integrate the surrounding urban markets, farmed fish are easily integrated in the fish consumption supply network.

The results show also contrasted situations between the Eastern and the Central Region of Cameroon. In the Central Region, the activity is new and it has developed smaller pond areas, fish cycles are shorter. A significant difference (p<0,05) appears in the size of the fingerlings stocked (Table 1). In the Eastern Region, increasing the production of fish in the pond dams depends on the integration of nurseries production inside the fish farm or improving supply through collaborative contracts with neighbours. Analysis elements and comparison with other descriptions (PDCE, 2015), tend to indicate that even if production is smaller than in the Eastern Region, yield is higher depending on the use of bigger fingerlings and lower stocking densities. It must be underlined that intensive models in Benin, that have often benefited from subsidies, generate less added value than the traditional systems and do not resist to the suspension of subsidies' (Odjoumani, 2014). At a larger scale, kinetics of adoption are varied and depend on the local conditions (endogenous evolution in Eastern Region) but also on the technical reference and the local political frame promoted. The various field reports attest of a willingness to intensify in Côte d'Ivoire; this ongoing process is linked to local socio-economic contexts. Lessons from China are interesting with fish in ponds yield improving from 724 to 5 217 kg/ha between 1979 and 2003 (FAO, 2005).

## 5 Conclusions

We want to insist on two difficulties met trough this study. Only an understanding of the fish breeding system including all the fish and the ponds managed, and seeking how each fish cycle fits in the global management of the producer is in capacity to provide reliable fish production data which are also needed to provide relevant economic data. This point difficult to investigate through that kind of appraoch and needs to be deepened. In spite of the little interest given by the governments, (Nguivoum 2014, Odjoumani, 2013), governments appeal for intensive technologies, the described extensive fish farming discreetly evolves with interesting contributions to sustainable development and poverty alleviation, especially in post-forested areas. This review confirms the resiliency of these models, their ability to supply farmed fish, at an affordable price for vulnerable populations and preferred to other fish supplied. With the reinforcement of their production, fish farming products integrate longer value chains generating higher added value and lots of multiplicative positive effects.

# A food systems approach to aquaculture: re-orienting farming systems for improving nutritional outcomes

Andrew Thorne-Lyman, Sven Genschick, Michael J. Phillips, Shakuntala H. Thilsted & Patrick Dugan

## 1 Introduction

The global nutrition community has shown increasing interest in harnessing agriculture to maximize benefits for the nutritional status of populations, particularly the poor and vulnerable. Often termed "nutrition-sensitive agriculture", the momentum for this movement comes largely from the recognition that: (1) rising incomes alone do not necessarily translate into improvement in dietary quality or reduction in the prevalence of under nutrition; (2) health systems alone are poorly equipped to address a multi-causal problem with deep and wide roots that include social and gender inequality, lack of ability to afford the foods that are richest in essential nutrients; and (3) large numbers of poor, smallholder farmers in countries in which under nutrition is most prevalent represent an under-utilized opportunity for sustainable improvements in under nutrition. In order to reduce under nutrition while at the same time avoiding rapid rises in over nutrition and non-communicable diseases observed in many parts of the world, greater multi-sectoral coordination that bridges the agriculture, health, and nutrition sectors is needed.

To date, however, little of the momentum of "nutrition-sensitive agriculture" has carried over into the aquaculture and fisheries sector, despite the promising nutritional content and known health benefits of fish. We argue that conventional approaches to agriculture and aquaculture in aquatic agricultural systems limit the scope for improving round the year availability of nutrient-rich foods for poor populations and that changes to existing approaches could improve the benefits. This paper explores the use of a food systems framework to identify opportunities to modify conventional approaches to aquaculture in order to lead to beneficial outcomes for human nutrition.

## 2. The need to revise agricultural policies to better address modern nutritional problems

Historically, agricultural policies focusing on increasing the productivity of staple foods have been highly successful in increasing the availability of energy. But as noted by Pingali (2015), a revision of those policies is needed to better address the nutritional problems of today. Dietary risk factors are the top contributor to the global burden of disease, and include (among others) low intake of fruit, vegetables, nuts and omega-3 fatty acids (IHME, 2014). While the Green Revolution led to a marked decrease in the price of staple grains over time, the real price of foods rich in micronutrients increased during that same period, and it is plausible that these increased prices have led to reduced dietary quality (Herforth and Ahmed, 2015). Recent reviews of own-price elasticity versus cross-price elasticity suggest that the most effective way of increasing access to foods of high nutritional quality by poor populations is to increase production of those specific foods, rather than making staple foods cheaper (Herforth and Ahmed, 2015).

Aquatic agricultural systems are diverse fishing and farming systems in which the annual production dynamics of fresh water and/or coastal ecosystems provide unique possibilities for crop diversity, fish diversity, and ultimately, dietary diversity of humans. Particularly in Asia, fish produced in such settings is an important contributor of animal-source foods and micronutrients in the diet: from 1950 to 2012, the annual supply of fish for food per capita more than tripled from 6 kg/capita/year to 19.2 kg/capita/year (HLPE, 2014). Since 1990, most of this growth came from aquaculture. While greater fish supply can be seen as a step in a positive direction, the shift from wild fish to farmed fish may have adverse implications for nutrition, given differences in nutrient composition and lower duration of availability of farmed fish, under conventional approaches to aquaculture (Thilsted, 2012). New innovations are needed to optimize the potential for aquaculture and agriculture to lead to nutritional benefits.

## 3. Expanding ‘classical’ views on the role of food production: the food systems approach

Taking a food systems approach to aquaculture helps to expand the classical view of production systems as isolated entities encompassing inputs, processes and outputs. It embeds production systems into a wider context of mutually, influencing interrelations with the environment, food utilization and consumption (Herforth et al., 2015). Given that nutrition is the result of multiple interlinked factors spanning across sectors, systems frameworks can be particularly useful in helping to understand how different dimensions of food systems interact and influence outcomes. For example, great attention has been placed on the role of women in food systems, and how their participation in agriculture can have positive benefits on control of income and assets derived from agriculture. At the same time, engagement in agricultural activities can influence women's health or that of their infants, by virtue of increased energy expenditure or increased labor burden and reduced capacity to feed and care for their infants. Understanding these types of implications is important for harnessing the potential of agriculture and aquaculture to have nutritional benefits.

## 4. Opportunities in aquaculture farming design for improved nutrition: examples from Bangladesh

Having outlined the key characteristics of a food system approach, some examples of ways to redesign farming systems in aquatic systems are given below:

**Opportunity 1: Pond polyculture with micronutrient-rich, small fish to increase fish availability and access for nutrition**
The inclusion of micronutrient-rich, small fish ('mola', *Amblypharyngodon mola*) in homestead pond polyculture systems in Bangladesh provides more fish for consumption and sale. Usually, in polyculture systems, a number of different species of similar large size and with a long rearing time are cultivated. In Bangladesh, research has shown that the simultaneous cultivation of micronutrient-rich, small and large fish, mainly native carp species leads to an overall increase in total production of a higher nutritional quality, without use of additional inputs. This results in a sustainable intensification and as small fish breed in ponds and their harvest period is shorter than for large fish; multiple, frequent harvests are possible, thereby increasing access to critical nutrients, as well as providing regular additional income (Thilsted and Wahab, 2014).

**Opportunity 2: Pond dyke farming as integrated aquaculture-agriculture systems**

For diversifying production and thus diets of rural households in Bangladesh, the cultivation of vegetables (e.g. orange sweet potato) and fruit on pond dykes is being promoted by WorldFish as an integrated, multifunctional farming system. This results in increased availability of non-staple foods that provide complementary nutrients to those from fish and greater dietary diversity, year-round (Islam et al. 2011).

**Opportunity 3: 'Gender-sensitive' gill net for empowering women in aquaculture and improving their access to fish**

A gender transformative approach aims to empower women through participation in aquaculture production. Considering cultural norms, a gill net, designed in the World Fish USAID-funded project: Aquaculture for Income and Nutrition (AIN) enables women to catch fish from the pond dyke, without having to enter the pond. This has eliminated the constraint which women faced in harvesting fish and thereby empowered them to take an active role in aquaculture and increase their control over access to fish, on a regular basis (Islam et al., 2015).

## 5. Conclusion

Food systems approaches can help to unlock the potential of agriculture and aquaculture for nutrition. As indicated by the above examples, small modifications in farming design can have large impacts on the performance of production systems and enhance their potential to benefit nutritional outcomes.
