Rooftop water collection, drip irrigation and plastic mulching in home garden conditions in drought prone areas of Cambodia

In Cambodia, drought can have different impacts: delay of rainfall onset in early wet season, erratic variations of rainfall onset, early ending of rains during wet season, and longer dry spell in July and August. This technology describes three different technologies and analyses the costs and benefits of their combined application: rooftop water harvesting, drip irrigation and plastic mulching in home garden conditions. As a result of the combined application of those good practices (GPOs), the resistance against drought is increased and a second cropping period is possible. The GPOs have been tested and validated in 19 Farms in the Kampong Speu (3) and Oddar Meanchey (16) Provinces in Cambodia.

How to buffer impacts of climate variability and dry spells in home gardens by using botanical pesticides and liquid compost, Cambodia

This technology offers a low-cost method used in Cambodia to control and manage pests for crop production while limiting adverse impacts of residue toxicity. It describes the methods of producing botanical insecticides and describes how to produce compost using the heap method and how to make liquid compost. The costs and benefits of the combined application of botanical insecticides with the production and use of liquid compost is presented.

Increasing flexibility in crop production through DAPOG nursery to reduce the impact of droughts and floods in Cambodia

Cambodia is highly vulnerable to natural hazards such as droughts and floods, which annually occur and often significantly affect the agricultural sector as crops are damaged or destroyed. To reduce these adverse impacts flexibility in crop production is essential. Adopting the practice of Dapog nursery has helped to increase farmers’ flexibility in crop production and has reduced losses in both wet and dry conditions. The Dapog nursery can be constructed on various surfaces, such as in the fields, on small portions of land, or even on concrete floors as long as there is a reliable water source nearby. It allows seedlings to grow quickly in a relatively small space. Furthermore, the strength of young seedlings (10 to 14 days old) is improved. Consequently, they suffer less from the transplanting shock and are more resistant to biotic and abiotic stresses like pests, floods, droughts and storms. This method takes less time to construct than conventional seedbeds and reduces the amount of labor needed as the pulling of seedlings is eliminated. As a result and due to the flexibility of this method, the Dapog nursery proves to be a good practice to potentially increase yield and additional income as well as to contribute to people’s food and nutrition security.

Management of self-recruiting species in aquaculture

In farmer-managed aquatic systems, poor people do not always have the resources to stock ponds with different fish species. Furthermore, in the dry season, water bodies dry out and access to food sources becomes limited. Self-recruiting species (SRS) are animals that do not require repeated stocking in farmer-managed systems and include both indigenous and exotic species. Management strategies for the maintenance and enhancement of SRS include: keeping of breeding stock, re-stocking of collected juveniles, and screening of pond entrances. These strategies help increase the yield of SRS, without extra financial inputs. This makes them particularly important for poor communities, especially during the dry season when access to other waterbodies is limited.

Management strategies to optimise production of and access to Self Recruiting Species (SRS)

Aquatic animals that can be harvested sustainably from a farmer managed system without regular stocking are referred to as self recruiting species (SRS). A range of indigenous and introduced fish species; as well as molluscs, crustacea and amphibians are inevitably present in many rural aquaculture systems, even where attempts have been made to eradicate them. SRS resource systems operate at the interface of capture fisheries and aquaculture, involving active management and private ownership of animals during all or part of their life cycle, but remaining closely linked to the wider, natural aquatic ecosystem. Active management of wild aquatic animals on farms serves not only to increase their availability for harvest, but to conserve the natural aquatic biodiversity of rice based farming landscapes.The technology characterizes the role of self-recruiting species in different aquaculture systems, and offers management approaches that enhance the production of and access to such resources by the poor.
