Peer to Peer Pass-on Approach with Women

Peer to Peer Pass-on Approach with Women [Бангладеш]

Terre des hommes and Greendots introduced the Peer to Peer pass-on system to enable women's groups in Bangladesh to spread the Keyhole Garden technique within their communities with the aim of enabling year-round homestead vegetable production despite the risk of flooding and tidal surge.

2. Описание Технологии УЗП

2.1 Краткое описание Технологии

Определение Технологии:

The Keyhole Garden model of homestead vegetable cultivation enhances the resilience of families living in areas with climate-related hazards, such as flooding and drought. Keyhole gardens have been shown to increase vegetable production in all seasons, thereby improving household food autonomy and dietary diversity.

2.2 Подробное описание Технологии


First initiated in Ugandan communities by Send a Cow UK, the keyhole garden technique is widespread in Africa. In 2011, Terre des hommes (Tdh) and Greendots piloted Keyhole Gardens for the first time in Asia, effectively adapting the design and methodology in Africa to the conditions of flood prone areas of Bangladesh, and eventually India. The garden is a good way to enhance dietary diversity, especially for poor/landless families.

Keyhole gardens consist of a raised circular garden made of clay, shaped like a horseshoe or keyhole, with a maximum diameter of approximately three meters. For flood prone areas in Bangladesh and India, the plinth height depends on the location and is typically the same as the house plinth to resist flooding. A compost basket is built at the center of the garden. Organic matter (kitchen cuttings) and residual water are added on a regular basis through the compost pit. In some countries, bricks or stones are used to make the plinth.

The keyhole garden is a typical Low External Input Sustainable Agriculture (LEISA) approach that includes integrated composting, water retention, use of local materials, natural pest and disease control techniques, natural soil fertility measures, and proximity to the kitchen for both harvesting and care of the garden. In regions with mild conditions of flooding, tidal surge and drought, the garden increases the duration of gardening period during the year thus reducing the risk of disaster. In the aftermath of cyclone Mahasen, keyhole gardens demonstrated DRR utility: although many were partially damaged, none had to be rebuilt entirely. Where plants did not survive the storm, users were able to sow seeds immediately. On the other hand, the traditional ground-level plots used for pit and heap gardening were completely flooded / waterlogged and unusable.

Benefits of the technology include: compact size, proximity to the household for convenient maintenance and harvesting, composting of kitchen cuttings in the basket; and an ergonomic structure (raised, accessible). The small size is also ideal to facilitate training on vegetable growing, soil fertility and pest & disease management to first-time gardeners and students in schools. Keyhole gardens are highly productive—in Lesotho a typical garden can satisfy vegetable needs for a family of eight persons (FAO, 2008). Combined, these factors are scalable as an appropriate technology for landless and marginal farmers. In Bangladesh, the gardens enabled families to produce vegetables even during the monsoon period. As the keyhole garden normally does not need to be rebuilt every year it is a more efficient technique in the long-term than traditional methods such as pit and heap.

Users say that their garden produce tends to be larger and tastier than conventional gardens or market produce; and many indicated that they were able to meet their own vegetable consumption needs and to sell surplus or gift vegetables. For some women it was difficult to access sufficient amounts of soil, which meant that they needed to walk long distances to build the plinth. (Fortunately many received support from other villagers.) Secondly, during the monsoon, while most of the land is flooded, the keyhole garden remains dry. Consequently, it may provide shelter to certain animals (e.g. rats) and attract higher number of pests. Regardless of these two limitations users agree that the benefits greatly
outweigh any observed limitations.

Комментарий, краткое описание:

The Keyhole garden was originally developed by African farmers to preserve their crops from the wind and the sand. Locally adapted in Bangladesh in Afzal’s vegetables garden with the help of Terre des hommes staff, the Keyhole garden can also protect the crops from the heavy monsoon rain and the salt water brought by flooding and storms. These literally destroy the crops. Widely adopted, it could help in preventing malnutrition by preserving the farmer's crops.

“Two days ago, my vegetable garden was wrecked by salt water and the monsoon rains”, says Afzal, who was the first person to test the new design proposed by Tdh and its technical partner Greendots. “The storm destroyed everything – except the keyhole garden, which is intact.”

4.2 Спецификация / пояснения к техническому рисунку

Gardens should be built in close vicinity to the beneficiary’s house, because gardens that are easily accessible and clearly visible are visited more regularly and maintained better.

The design is highly adaptable to local conditions and availability of free construction materials. The radius of the garden is 150CM and the delineated radius of the circular compost basket (in the center of the garden) is 45cm. The diagrams show (1) the location is near to house as an entry point for maintaining the garden; (2) the plinth is built to the same level of the house and a step is included where the plinth is high; (3) mulching to conserve the moisture; (4) interplanting a diversity of vegetables for both good vegetable health and good family nutrition; (5) using interplanted natural repellent plants as pest control for vegetables; (6) covering the basket during times of high sun intensity or heavy rain; (7) using liquid manures and plant teas as top dressing fertilisers.

Establishing what is the best height for your plinth very much depends on the local climatological conditions. In Bangladesh, the plinth is built from subsurface clayey soil, typically 2-3 feet in height - dependent on the location and level of seasonal flooding. The house plinth is a good gauge for how high to build the garden plinth. If the plinth is built too high, the roots of the plant will not be able to access sufficient water; and if built too low the next flood during the monsoon season may destroy the garden. Depending on dryness or soil/groundwater salinity, daily maintenance usually includes irrigating the soil. The outer rim of the plinth is protected with mud (and plastic or cloth) or stones. On top of the plinth is a mixture of soil and compost/manure (ratio 2:1) sloped up to the basket at a 30 - 40 degree angle. The central compost basket is filled with layers of fresh and dried vegetable matter, manure and ash to ensure that the soil fertility of the garden.

Women devised a number of different solutions to protecting the wall of the plinth and garden: Plastic bags, a combination of rice sacks (around the plinth edge) and plastic entrance way because of wear and tear (rice sacks erode faster), palm matting and old cloth. Some women put extra manure in the plinth walls to protect against flooding.

Sam Rich (www.fourthway.co.uk) has produced other technical drawings in addition to "How to Make Liquid Manure" such as: "How to make a Natural Pesticide" and "How to Make Plant Tea". There is also a version of the "How to Make a Keyhole Garden" in English from the experience in Africa.

Firstly, building the garden requires an initial investment in terms of labour and (locally available) inputs, such as soil and wood and clayey soil for the plinth (stones and bricks are frequently used for the plinth in Africa). These inputs are available on the homestead or in the community and generally free of cost. In rare cases families paid to have soil carted to their homestead, thus increasing the initial structural costs.

In Bangladesh, women referred to the time spent working on the keyhole garden as “leisure time” and that they do this work after they have completed their domestic chores. Women estimated 45 minutes daily of such activity to maintain the garden. Calling it "leisure time" is misleading, but it suggests that most women generally enjoy working in the garden and do not regard it as heavy labour. The daily wage of an agricultural labourer differs per region. In Tdh's project area, wages are relatively low, especially for women. While male labourers may earn 200 BDT ($2.50) per day, women usually earn only 90 to 150 BDT. For the calculation, we applied the principle of equal pay for equal work, taking 200BDT per day.

4.8 Наиболее значимые факторы, влияющие на стоимость затрат

Опишите наиболее значимые факторы, влияющие на стоимость затрат:

Over the last few years, people in disaster-affecteed areas of Bangladesh have become familiar to receiving during humanitarian distributions; and expect “hand-outs” if they were to participate in a development project. The Keyhole garden project, however, follows the LEISA approach and does not rely on giving free inputs to the participants. (In a few cases where the local population was lacking seeds and experience in seed production, women's groups were given seeds and training.) A lack of reliance on external inputs or subsidies contributes to the sustainability of the project. The inputs (clay, manure, sticks, rocks, etc.) are locally available and usually do not require additional expenses. This may not be the case in all contexts.

6. Воздействия и заключительные положения

6.1 Влияние Технологии УЗП в пределах территории ее применения

Социально-экономическое воздействие


производство сельскозяйственных культур

Количество до применения УЗП :

<5% of pilot families growing vegetables in all 3 seasons

Количество после применения УЗП:

50% of the pilot families able to grow vegetables in 3 seasons

Комментарий/ пояснения:

Before the project started, the majority of the participants were not able to produce vegetables year round. Especially during the monsoon months, people were dependent on produce available at the local market. The baseline survey indicated that in both regions more than 50% of the households would cultivate vegetables for a maximum of 3 months per year and in Kurigram 30% of the participants were not able to grow vegetables at all.
This situation has changed significantly after the introduction of the keyhole gardens. At least 50% of the households were able to produce vegetables during each season. Where in the past almost no one was able to cultivate during the monsoon period, now on average 63% of the households in Kurigram and 73% of the households in Patharghata were growing vegetables in the wet season.
The summer figures are actually lower than the monsoon figures. Seeds did not germinate well, because participants were not fully prepared to deal with the dry and saline conditions during this season. Learning from this experience, and with adequate support from Tdh, participants should be able to achieve higher cultivation rates in the future.

разнообразие продукции

Количество до применения УЗП :

Average of 2-4 types of vegetables grown.

Количество после применения УЗП:

Average of six types of vegetables grown

Комментарий/ пояснения:

During the field visits and individual interviews in June 2013, the majority of the participants indicated that in the keyhole garden they usually grow 6 or more different types of vegetables at any given time. This is a marked difference from previous years, when the majority of people in Patharghata would only grow 2 types of vegetables. In Kurigram the baseline was somewhat higher (31% cultivated 4 types of vegetables per year on average), but still significantly lower than in 2013. By increasing the different types of vegetables grown, the families have access to a more diversified diet.

очень позитивное

Насколько получаемый результат сопоставим с текущими расходами по поддержанию технологии (с точки зрения землепользователей)?
Эффективность затрат в краткосрочной перспективе:

очень позитивное


No long term study available.
In most cases no (or very low) investment cost in materials and a low investment cost in labor was necessary. Thus the establishment and maintenance costs are relatively low compared to the benefit of increased homestead vegetable production and access to produce for increasing dietary diversity. The benefit increases when the technology supports resilience to flooding as was the case from flooding (Kurigram), and partially from a cyclone (Patharghata).

6.5 Внедрение Технологии

  • более 50%
Если возможно, дайте количественную характеристику (число домохозяйств и/или площадь применения):

333 from the pilot study. Subsequent projects by Tdh from 2013-2015 have seen over 3'500 keyhole gardens created in Bangladesh and India.

Среди применяющих Технологию землепользователей, какова доля лиц, применяющих её по собственной инициативе, т.е. без какого-либо материального стимулирования со стороны?
  • 90-100%

All of the adopters did so with training but without inputs. Spontaneous adoption of the Keyhole Garden without training is not easy to measure, but Tdh's experience shows a conservative average of 11% (38 of 333 gardens).

6.6 Адаптация

Была ли Технология УЗП изменена в недавнее время с целью адаптации к меняющимся условиям среды?


Если да, укажите, по отношению к каким именно изменяющимся условиям среды произведена адаптация?

6.7 Сильные стороны/ преимущества/ возможности Технологии

Сильные стороны/ преимущества/ возможности по мнению землепользователей
Seasonal local agriculturalists reported that gardens yielded high productivity with good vegetable quality and diversity; withstood heavy monsoon rains lasting for several days; and withstood a salt water tidal intrusion that destroyed adjacent traditional gardens. During the FGDs women clearly expressed a lot of enthusiasm for the project and all the participants indicated that they would continue with their garden, even if Tdh would no longer provide any support. One volunteer reported successfully harvesting five common vegetables usually impossible to grow in monsoon conditions:
- In plain land we can cultivate once in a year but in keyhole garden we can harvest vegetables in three seasons and they don't go underwater in the rainy season
- Save money for the family: don't need to buy fertilizers or vegetables and some people earn money by selling the garden product
- We can collect vegetables for the children’s requirements directly from the garden when they need them
- In a small space you can have lots of different vegetables and the taste is much better because the garden depends on compost – no chemicals
- The cost to make is it very low, but you need labour; by our own labour we can build it
- Because of composting the garden can always get nutrients
Сильные стороны/ преимущества/ возможности по мнению составителя или других ключевых специалистов
The keyhole garden project has been very successful and has largely achieved its core objective to improve year-round access to nutritious food from the homestead area. These benefits are summarized again as:
- Appropriate size for landless homesteads, also ideal to facilitate training on LEISA techniques to first-time gardeners and students in schools.
- Proximity to the household for convenient maintenance and harvesting, composting of kitchen cuttings in the basket;
- Ergonomic structure (raised, accessible).
- Highly adaptable to local conditions that supports resilience to flood and drought conditions.
- Highly productive—families produced vegetables even during the monsoon period.
- As the keyhole garden normally does not need to be rebuilt every year it is a more efficient technique in the long-term than traditional methods such as pit and heap.

Therefore, the reviewer did not suggest any major changes to the technique or project; rather to focus on specific issues that could help making the project more efficient and that could help broaden its impact.

6.8 Слабые стороны/ недостатки/ риски Технологии и пути их преодоления

Слабые стороны/ недостатки/ риски по мнению землепользователей Возможные пути их преодоления/снижения?
No major weaknesses in the technology or design were expressed. However for some women it was difficult to access sufficient amounts of soil, which meant that they needed to walk long distances to bring soil to build the plinth.
In coastal areas where saline intrusion in groundwater and soils is on the rise, growing and irrigating crops is difficult in the dry season.
Some women received support from other family members or neighbours; identify a support network for families having challenges to access soil to build the plinths.
Continue to look for for alternative irrigation sources and/or groundwater recharge innovations as well as soil conservation techniques to protect against salinity. Likewise, saline resistant vegetable varieties may be available.
Слабые стороны/ недостатки/ риски по мнению составителя или ответственных специалистов Возможные пути их преодоления/снижения?
More careful planning of the location for the keyhole garden is needed. In Patharghata 11 women decided to relocate their garden within the first year. This suggests that the women appreciate the benefits of the garden, but having to break down and move the garden is a rather laborious activity.
Not surprisingly, women who have less time to work in the homestead area, e.g. due to work or other out-of-home responsibilities, are not able to maintain their keyhole garden so well.
Spend more time to assist the participants with identifying the most suitable locations to construct the garden for a keyhole garden in the homestead area at the start of the project.
While maintaining a focus on women, involve the husband or other family members/ neighbours and ensure that they are also trained and ensure that the garden is clearly visible and can be accessed.

7.1 Методы сбора/ источники информации

  • выезды на места, полевые обследования

50: The project evaluation took place from 4 June to 12 June 2013 with field visits in the two project areas, Kurigram and Patharghata. In total 5 Focus Group Discussions (FGD), with approximately 10 participants per FGD, were organized during this period. The core objective of the FGDs was to assess whether keyhole gardens have contributed to increases in vegetable production throughout the year and if this has lead to improved consumption practices. The additional aim of the FGDs was to learn directly from the participants about their nutritional needs and their ideas to further improve the keyhole garden project.

  • опросы землепользователей

8: In addition to the FGDs the consultant carried out eight individual interviews with project
participants from the two regions. The individual interviews provided more detailed
information about production techniques and about the impact of the project at the
household level.
