The main aim of the SSWM Toolbox is to be a reference tool to provide ideas for improving the local water and sanitation situation in a sustainable manner. Results depend largely on the respective situation and the implementation and combination of the measures described. An in-depth analysis of respective advantages and disadvantages and the suitability of the measure is necessary in every single case. We do not assume any responsibility for and make no warranty with respect to the results that may be obtained from the use of the information provided.

4 1. ConceptBackgroundThe term vertical garden refers to any kind of construction and support structure for growing plants in an upwards-directed, vertical way and thereby efficiently and productively making use of the existing space.A huge variety of different designs and concepts are available.The design of vertical garden depends on the available material, space and local preferences as well as on the creativity and imagination of the users.Crops that can be grown comprise food crops (vegetables, fruits, herbs) and non-food crops (e.g. ornamental plants, medical plants).4
5 2. How it can optimize SSWM Important factors how Vertical Gardens optimize SSWMVertical gardening aid to advance the productivity levels of urban and sub-urban agricultural production sites where most often available space is the biggest agricultural limitation.Vertical Gardens utilize soil, compost, vermicomost, acrylic material as well as aquaponic and aeroponic solutions as growing media thereby maximizing the use of the resources while compromising the degradation of nutrients by using various planting medium.5
6 2. How it can optimize SSWM Important factors how Vertical Gardens optimize SSWMVertical gardening can re-utilize greywater, reclaimed water or the fertilization with urine.It maximizes the use of space by using sacks, bags, flowerpots and all kinds of available receptacles like bins, cans, tins, bottels, tanks or boxes and even the unused places like on the roof of houses, balconies, on the top of walls or just hung up.6
7 3. Design Principals Few Different Vertical Garden Designs Further vertical garden solutions that allow for a good utilization of available space are cultivation arches, cultivation towers or cultivation bags.Other systems like cultivation umbrellas, cultivation bangles or some kind of cultivation tat have also been proven usefulCultivation arch, cultivation towerand cultivation bag, Gampaha, Sri Lanka.Source: RANASINGHE (2008)Cultivation umbrella, cultivation bangle and cultivation tat, Gampaha, Sri Lanka.Source: RANASINGHE (2008)7
8 3. Design Principals Few Different Vertical Garden Designs A variety of different substructures like cultivation ladders, pyramids or racks can be designed and constructed to grow plants verticallyCultivation Ladder, Cagayan de Oro, Philippines.

9 3. Design Principals Few Different Vertical Garden Designs Walls, murals and exterior walls of houses are also an often used as a vertical gardening alternative either just as beautification of the wall or to grow vegetables and other crops along the wall.Either the wall will be modified with additional bricks or holders can be used for growing plants on the surface of the wall.Plants should be selected according to the orientation of the wall.Cultivation wall, cultivation holder, Gampaha, Sri Lanka Source: RANASINGHE (2008)9
10 4. Operation and Maintenance To make sure plants do grow well on vertical surfaces regular water and nutrient supply needs to be ensured.Irrigation techniques like bottle irrigation or regular watering with watering cans and alike can be used.Essential plant nutrients like Nitrogen, Phosphorus and Potassium should be applied according to the needs of the plants, this can either be done by adding synthetic fertilizers or by making use of compost, vermicompost and/or human urine or other organic fertilizer sourcesThe use of treated or partly treated greywater and reclaimed water can also be a cost effective alternative water and nutrient source particularly in water scarce areas.10
11 5. ApplicabilityVertical gardening is an excellent opportunity of growing food in areas where space is limited, particularly in densely populated urban areas.The different vertical garden technologies are an effective, simple and sustainable method of enhancing food security for urban communities, slum dwellers and other communities where agricultural production areas are limited.Most solutions can easily implemented with locally available material at low cost while it offers at the same time a livelihood opportunity and contributes to the local food security situation.11
12 6. Advantages and Disadvantages Low costMinimal agricultural area requiredContribution to household food security and alleviation of food shortages and povertyReuse and recycling option for human excreta, biodegradable wastes and greywaterTemperature insulation by growing plants on the walls of housesSimple and easy to understandDisadvantages:Unpleasant odours may appear during the irrigation with greywater and urineA certain amount of labour requiredRegular watering or irrigation system has to be in place12
