What is the importance of rice-fish culture in agriculture?

Rice-fish culture controls insects which are harmful to paddy (rice). Rice-fish culture reduces the risk of crop failure. Rice-fish culture is useful in controlling weeds. Rice-fish culture increase the production of rice as fish stir up soil nutrients which are very helpful for rice crop.

What are the advantages of integrated rice and fish farming?

Advantages of Integrated Rice and Fish Farming:- The following are the advantages of integrated rice and fish farming. Farmers can get extra income from rice-fish culture along with main crop yield. Rice-fish culture controls insects which are harmful to paddy (rice). Rice-fish culture reduces the risk of crop failure.

What is meant by integrated fish farming?

It is nothing but growing fish in rice (paddy) fields by using the same area without impacting of rice quality and yield. Integrated fish farming provides the option for getting extra income along with main crop (rice). Though this system has proven profitable, it has its own advantages and disadvantages.

What are the disadvantages of fish and rice farming?

Rice and fish farming requires restricted use of pesticides. This integrated system of fish and rice requires more water than paddy (rice) cultivation alone. Rice yield is less in this system as trenches are required about 45 cm below the paddy bottom. Due to these trenches, the paddy cultivation area will be reduced and it results in lower yields.

What are Yi1 and Yi0?

where, Yi1 and Yi0 are two counterfactual outcomes of IRFFS adoption and non-adoption. Bootstrapped standard errors are used to do the significance test of ATT which takes into account the variation that arises in the matching process. As such we implemented different matching estimators using the PSM algorithm developed by Becker and Ichino (2002) with STATA 12.1.

How to evaluate IRFFS?

If IRFFS was randomly assigned to households (like a randomized experiment) we could evaluate the causal effect of technology adoption on household welfare by differencing the mean of the welfare indicator between adopters and non-adopters ( Heckman et al., 1998 ). But we cannot do that in our case because as stated earlier IRFFS adoption is non-random. In such a situation we have to use such a method which can mimic the experiment. Therefore we use propensity score matching (PSM) method, which is a commonly used non-experimental approach, to estimate the causal effects of IRFFS adoption on household welfare in a cross-sectional sample without random adoption. It balances the distributions of observed covariates between a treatment group and a control group based on similarity of their predicted probabilities of adopting IRFFS (their ‘propensity scores’). PSM creates: the conditions of a randomized experiment; makes the incomparable comparable and it is insensitive to functional form ( Mendola, 2007; Rosenbaum and Rubin, 1983 ). 2

Why should water be retained in the rice fish system?

The water should be retained in the rice–fish system to develop natural food and keep the nutrients for rice . The feeding rate applied for fish in the rice–fish system should be much lower than in ponds to maximize use of natural food. The use of inorganic fertilizer should be minimized.

What was the effect of commoditization of crops during the 20th century?

Commoditization of several staple crops during the 20th century meant that it became economically preferable for many farmers to reject traditional, interconnected agriculture in favor of monoculture. Monoculture requires prioritizing the yield of a single species, and as a result, foodstuffs that were once “by-products” or perhaps even “coproducts,” are increasingly treated as hindrances to one-crop production.

What is a group approach in rice farming?

A group approach is the key for sustainable development of rice–fish farming, which facilitates the value chain development, effective sharing of experiences and lessons and collective production activities, and supports the farmers in continuing the practices after the financial support is withdrawn.

Is rice a food crop?

Rice is widely cultivated in Egypt as a major food crop. According to the Central Agency for Public Mobilization and Statistics (CAPMAS), about 0.6 million ha of agricultural land were cultivated with rice in 2015/2016 ( http://www.capmas.gov.eg/Pages/IndicatorsPage.aspx?page_id=6151&ind_id=2361 ). The potential of rearing fish in rice fields in an integrated system is increasing. In fact, rice–fish farming has been a common practice among rice farmers in many areas in the Nile Delta region for many years. The total production of fish in rice fields increased from 10,000 t in 1999 to 34,000 t in 2014, with tilapia representing about 48% of this production ( GAFRD, 2016 ). However, the production declined drastically to reach 13,535 t in 2016 ( GAFRD, 2018 ); probably due to the continuous shrinking of the lands allocated to rice cropping. One or more ditches (about 50 cm deep and 100 cm wide) are generally dug along the rice field and used as a nursery and refuge for the fish. Because the rice-growing period is not sufficient to produce market-size fish, juvenile fish reared in rice fields are subsequently transferred to other aquaculture systems for fattening. When the rice field is drained for harvesting, the fish are segregated in the ditches where they can be easily collected.

Does tilapia reduce rice?

Available results indicated that the presence of the fish with rice crop does not reduce rice harvest, but increases revenue over rice monoculture. This suggests that rice–fish integration could be a viable option for income generation for small rice farmers in many African regions.

What is sustainability movement?

The sustainability movement is global. When you look at what is happening with rice and sustainability around the world, you encounter an alphabet soup of acronyms and abbreviations for platforms and initiatives created by organizations far and wide.

What is rice checker?

The Rice Checker, which Arkansas rice producer Mark Isbell builds and markets, is one of the many tools he uses to reduce the carbon footprint of rice production. Let’s be honest. You are probably getting tired of hearing the word sustainability. I know that I sometimes do.

What are the platforms and initiatives for farmers?

These platforms and initiatives include SAI (Sustainable Agriculture Initiative), SRP (Sustainable Rice Platform) and others .

What is FTM in manufacturing?

One place our industry has been at the table is at Field to Market (FTM), an alliance of corporations and producer groups from multiple commodities that have come together to illustrate continual improvement in sustainability using the Field Print Calculator.

What is the goal of supply chain?

The goal is for the supply chain to be able to provide confidence to consumers that genuine sustainable practices are being adopted or continued. Just because we know the things we are doing doesn’t mean that consumers do.

Where is Mark Isbell?

Mark Isbell is a fifth-generation rice farmer in Lonoke County, Arkansas, and a member of the USA Rice Sustainability Committee, liaison to Field to Market and a steering committee member for the American Carbon Registry initiative.

Is sustainability a word?

At its best, the word can sometimes still be vague and nebulous – fluid in its meaning depending on who it is that’s saying it. At its worst, it can be a word that co-opts and misappropriates the credit for activities done by farmers who have been focused on stewardship long before anyone determined that “sustainability” would be the word of choice by eager marketing departments.

What fish can be grown in paddy fields?

The depth of water and duration of paddy field, and rice cultivar plays the major role in selection of species in integrated system. Common carp or Mrigal (Paddy-cum-carp culture). Catla (Paddy-cum-carp culture). Tilapia (Paddy-cum-carp culture).

What is integrated fish culture in paddy fields?

Introduction of Integrated Rice and Fish Farming:- Well, what is integrated fish culture in paddy fields? It is nothing but growing fish in rice (paddy) fields by using the same area without impacting of rice quality and yield. Integrated fish farming provides the option for getting extra income along with main crop (rice). Though this system has proven profitable, it has its own advantages and disadvantages. Rice and fish farming is widely practiced in Asian countries when it compared to western counties.

What are the advantages of rice and fish farming?

Advantages of Integrated Rice and Fish Farming:- The following are the advantages of integrated rice and fish farming. Farmers can get extra income from rice-fish culture along with main crop yield. Rice-fish culture controls insects which are harmful to paddy (rice). Rice-fish culture reduces the risk of crop failure.

How much rainfall is needed for rice and fish farming?

It requires about 70 to 80 cm rainfall which is considered as optimum for this integrated system.

How are paddy fields irrigated?

Most of paddy fields are irrigated by common water channels and it is very difficult to check for water quality/pesticides. Growing fish in paddy fields may require more investment then rice culture alone. Rice and fish farming requires more labour then paddy cultivation alone.

How deep should a rice trench be?

When it comes to rice cultivars, deep water varieties are best for paddy and fish culture system. Trenches (deepened areas) should be made about 0.5 meter deep and minimum of 1 meter wide. Make sure to the trenches should be within 10 meter range from the paddy.

How far below the paddy bottom is rice?

Rice yield is less in this system as trenches are required about 45 cm below the paddy bottom. Due to these trenches, the paddy cultivation area will be reduced and it results in lower yields. Digging trenches makes difficult in draining the water.

Highlights

The first ES evaluation of rice-fish (RF) co-culture in the northwest of the Hu Line.

Abstract

Developing sustainable agriculture in ecologically fragile areas is important. To date, the ecological service value of the rice-fish co-culture in the northwest area of the Hu Line is unclear.

1. Introduction

Approximately 50% of the world’s population depends on rice; hence, rice plays a key role in addressing global food security ( Zhang et al., 2021 ).

4. Discussion

4.1. Characteristics of the ES values of rice-fish systems in the northwest of the Hu Line

5. Conclusion

The ES value of the rice-fish co-culture in Yinchuan was 266,691.89 RMB/hm 2/year, which was 35.72% higher than that of rice monoculture. The total value of the non-economic ecological benefits in the rice-fish co-culture, other than provisioning and tourism services, accounted for 71.78%.
