The floating garden practice is a local indigenous production system most successful in the wetland/submerged areas of selected south and south-western districts (Pirojpur, Barisal and Gopalganj) in Bangladesh. Floating garden agricultural practices have been adopted by local farmers for near two centuries. This technology describes how to construct and use floating gardens for seedling production of vegetable and spice crops in Bangladesh.
Floating agriculture (locally name as vasoman/dhap chash) is a local innovative crop production technology for the submerged ecosystem of the southern region of Bangladesh. Traditionally, the farmers of Gopalganj, Pirojpur and Barisal districts have been practicing the farming technology since about two centuries for adaptation with the flooded/submerged condition. To improve the traditional floating garden agriculture practices for growing cucurbits or creeper type of vegetable crops successfully research programmes were undertaken. This technology describes how the improved practice for vegetable production is implemented and managed.

Nepal ranks among the most vulnerable countries to extreme climate events. In general, rural areas where the population heavily depends on agriculture are the most vulnerable. High temperature during summer months and foggy weather combined with prolonged cold temperature spells during winter months often affect vegetable cultivations, such as tomato and onion. The protection of crops against adverse weather conditions becomes a priority to meet the household requirements especially in mid-hills region in Nepal.
In this context, tunnel farming is a simple and low cost practice to control the micro-climate surrounding crops by reducing the impacts of temperature fluctuations. It consists in the building of greenhouses-hut-like structures swathed in plastic that serve as cocoons, making it possible to grow vegetables off-season, securing the provision of food supplies throughout the year.
A keyhole garden (so-called because of its shape) is a round raised garden, supported with stones. Keyhole gardens are built in places where it is difficult to build normal gardens (rocky areas, shallow arid/or compacted soils, etc), near the entrance of dwellings to facilitate their watering with household waste water. Keyhole gardens are made with low-cost locally available materials. The production of a keyhole garden can be enough to feed a family of 8 persons. Such gardens can produce food all year round even under harsh temperatures and can support the production of at least 5 varieties of vegetables at a time - thus supporting dietary diversity. Compared to regular vegetable gardens, keyhole gardens require less labor (ideal for elderly, children or sick persons), less water and no costly fertilizers or pesticides. They act like an organic recycling tank, using your food and garden waste as fuel to grow vegetables! Crop rotation and growing of insect-repellent plants are important to balance nutrient demands, fight insects and plant diseases, and deter weeds. When a project introduced keyhole gardens in Lesotho, neighbouring villages outside the project intervention area were reproducing keyhole gardens on their own initiative, clearly indicating the success of the intervention and its potential sustainability. This technology gives a detailed step-by-step description of the building process of a keyhole garden.
Homestead gardening is a well known practice in the rural areas of Bangladesh, creating opportunities for year-round income, even when other income sources fail particularly due to water scarcity and drought. Homestead gardens use the small raised areas (chalas) around the homesteads. The management of close by homestead gardens benefits from using homestead wastes, sweepings and debris as organic matter, as well as from roof collection of irrigation water. Selecting vegetables and varieties which require less irrigation water enhances drought resilience. Homesteads gardens are a good practice for women in particular, who can manage activities and earn income with minimum support from their male counterparts.
Leaves of cassava, sweet potato, papaya and pumpkin are widely eaten in Africa. They are nutritious, tasty and inexpensive and can help to reduce hunger and malnutrition. Fresh green leafy vegetables and fruits start to lose their quality immediately after harvest, becoming damaged, wilted and eventually rotten. Storing and drying fruits and vegetables can provide a rural household with a better diet year round and a better income. One preservation method using very basic materials and methods for sun-drying are described in detail.
A smart farmer only sows high yielding varieties with disease resistance to minimize spraying and with tolerance to abiotic stress such as drought. Vegetable remains an important source of income generation and constitutes a key source of micronutrients. The Victoria vegetable hybrids assure farmers of improved nutrition, food and income security because of their high yields and tolerance to biotic and abiotic stresses.
The preservation of fruit and vegetables by simple sun drying is practised widely throughout arid and semi-arid areas, for example in Uganda. The use of low cost, solar drying technologies, can significantly improve product quality thereby providing practical opportunities for developing smallscale enterprise, particularly in rural areas, and creating employment for women's groups.
