“…Previous farm household modelling has utilised sophisticated methods to represent real producer-consumer communities, including the consideration of empirically-derived farm typologies based on statistical methods such as principle component and archetypal analysis [e.g. 34,36,37,38]. Our style-based approach differs in that it considers theoretically-derived generalizations (based on empirical research) that are potentially applicable across countries regardless of their income level [32,48] (cf.…”

“…We argue this is a critical limitation given both the contested nature of how farming futures could or should look [30,48] and previous findings of farm household models [e.g. 34,36,38]; what happens at the micro-level matters for population health.…”

“…When assessing farm heterogeneity, farm household modelling has tended to use empirically-derived typologies based on site-specific structural and functional features [e.g. [34][35][36][37][38]. In contrast, styles of farming arise from empiricallyderived theory based on observations in a range of locations and aim to identify 'patterns of coherence underlying this heterogeneity' [39].…”

Undernutrition is a major contributor to the global-burden of disease, and global-level health impact models suggest that climate change-mediated reductions in food quantity and quality will negatively affect it. These models, however, capture just some of the processes that will shape future nutrition. We adopt an alternative standpoint, developing an agent-based model in which producer-consumer smallholders practice different ‘styles of farming’ in the global food system. The model represents a hypothetical rural community in which ‘orphan’ (subsistence) farmers may develop by adopting an ‘entrepreneurial’ style (highly market-dependent) or by maintaining a ‘peasant’ style (agroecology). We take a first look at the question: how might patterns of farming styles—under various style preference, climate, policy, and price transmission scenarios—impact on hunger and health-supporting conditions (incomes, work, inequality, ‘real land productivity’) in rural areas? imulations without climate change or agricultural policy found that style preference patterns influence production, food price, and incomes, and there were trade-offs between them. For instance, entrepreneurial-oriented futures had the highest production and lowest prices but were simultaneously those in which farms tended towards crisis. Simulations with climate change and agricultural policy found that peasant-orientated agroecology futures had the highest production, prices equal to or lower than those under entrepreneurial-oriented futures, and better supported rural health. There were, however, contradictory effects on nutrition, with benefits and harms for different groups. Collectively the findings suggest that when attempting to understand how climate change may impact on future nutrition and health, patterns of farming styles—along with the fates of the households that practice them—matter. These issues, including the potential role of peasant farming, have been neglected in previous global-level climate-nutrition modelling but go to the heart of current debates on the future of farming: thus, they should be given more prominence in future work.

“…Fisheries play a vital role in nutrition, livelihood earning and export earnings in Bangladesh. Fishes contribute to 60% of animal protein intake, about 4.39% of gross domestic product and 2.46% of export earnings; approximately 1.4 million people are directly engaged in fishing, 11 million in part-time fishing and another 3 million in aquaculture activities [1][2][3][4]. However, the International Union for Conservation of Nature (IUCN), Bangladesh [5] assessed 253 freshwater fish species and revealed 64 as threatened species in Bangladesh, of which 9 were critically endangered, 30 were endangered, 25 were vulnerable, near threatened 27, least concern 122 and 40 data deficient freshwater species [5,6].…”

This study examines the growth and yield of Vietnamese koi with Thai koi for developing a suitable culture management technique of koi for sustainable production and unveiling the most cost effective culture of koi species. The study was conducted for a rearing period of 100 days in four farms at Gauripur upazila in Mymensingh district in Bangladesh. The treatment 1 (T1), treatment 2 (T2) are considered for Vietnamese koi and treatment 3 (T3), treatment 4 (T4) are considered for Thai koi with stocking density 1,72,900 per hectare for T1 and T3 and 2,47,000 for T2 and T4 at four different farms of study area. The ponds were stocked with an initial length of 0.75±0.01 cm and weight of 0.20 g in all the treatments. The culture period has the optimum level of physicochemical parameters. The study reveals that the maximum weight gain was in treatment T1 of Vietnamese koi and lowest in treatment T4 of Thai koi. Similarly, physical length, weight and survival of Anabas testudineus also followed the same trends as weight gain. Individually treatment T1 shows significantly higher specific growth rate than the other treatments. Besides, food conversion ratio was significantly higher in treatment T1 followed by treatment T2, T3 and T4. However, the mean fish production were 17092, 15000, 10746 and 10469 kg/ha in treatment T1, T2, T3 and T4 respectively. Consistently, highest growth, survival and higher net economic benefit from A. testudineus were found in treatment T1 among the four treatments. Vietnamese koi population of treatment T1 has appeared to be most suitable for good quality aquaculture practice for 100 days rearing semi-intensive system among the four treatments. Therefore, monoculture practice of Vietnamese koi is a perfect scheme of choice for a commercially viable and sustainable koi culture to meet up the protein deficit and as well as to accelerate the sustainable development of Bangladesh.

“…The supply of fish in the world has been fed an increasing slice by aquaculture (FAO, 2018;RAHMAN et al, 2019;AKTER et al, 2020;OLIVEIRA et al, 2020). One of the advantages is that it generates income for the aquaculture farmer, boosts the regional economy and improves the quality of life of the population (GAMBELLI et al, 2019;ARAVINDAKSHAN et al, 2020).…”
