Doing our daily business, we might not think about it much using our so-called sophisticated water closets which cost thousands of dollars to maintain and waste millions of litres of fresh water daily.
People in a refugee camp aren’t that lucky. Doing their business can often be very dangerous, especially for women. The pollution created is also a big problem and so are unsanitary toilet compounds that can’t deal with the volume. There are no pipes or costly sewer systems.
Jay Abraham from Biologic Design in the UK has coined the phrase ‘tree bog’ for the toilet system that simply uses an old essential habit that people in his native England used daily. As he describes ‘People used to do their business in a bucket in a closet and they would have a separate bucket of soil and sprinkle it over each time a deposit was made. It kept the smell away.”

The way the tree bog works is quite similar. Its floor is built up high, at least 1.5 metres above ground level. The space under the floor is enclosed by 2 layers of wire mesh filled with carbon material (hay, straw, dry grasses) to allow air flow, absorb excess nitrogen and provide a visual barrier. The human waste is covered with sawdust, ash or soil and breaks down, feeding the surrounding area that’s planted out with trees, grasses and ground covers. In less than a year there are fast growing trees & fruits such as papaya to pick plus shade and biomass to refill the wire mesh carbon wall.
For 30 years Jay has been using his tree bog invention on his own property, fine tuning it to be shared with the world. He’s supported many projects that are building the toilets in refugee camps.
Permafund has recently funded a tree bog in the Kakuma Refugee Camp in Kenya. Established in 1990, the camp has some 60 000 inhabitants with many living there in limbo for years and years.
Since then, Marcelin Munga from Food & Health Education (FHE) in Kakuma has attracted more funding to build another tree bog. Members of the Permafund team were invited to tune into a live Zoom workshop with Jay Abraham beamed in from the UK. Marcelin hosted some 20 people from the compound including 3 cooks and 2 educators and a number of mothers with their babies, eager to start building their own tree bog. The workshop members used tools previously purchased with the Permafund grant.
There were some technical difficulties with the Zoom, but we got see the site and meet the group. Jay gave a report from another camp where one of the tree bog toilets had caught the attention of UNHCR. They inspected it with a negative attitude and the intention to knock it down but instead left impressed and gave the tree bog their tick of approval.

Fences are often necessary for privacy, security and the safety of pets and children. As Mara Ripani explains, there are myriad ways to create them with plants, adding extra greenery to our built environment.
With populations increasing and cities and towns growing, we need to take every opportunity to introduce green into our built environment: ‘rewilding’ our surroundings, even in small ways. A living fence is a simple and effective way to start. There are many approaches to creating a living fence: what they all have in common is a thriving explosion of plants!
What is a living fence? Fences are commonly used for creating privacy (both visual privacy and by preventing access), for keeping pets and children contained and safe, and simply for marking property boundaries. With a bit of planning, all of these requirements can be fulfilled with a living fence: one that is made using plants on their own or by combining plants with an appropriate structure. Depending on its main purpose, the space available and your aesthetic preference, a living fence can take the form of closely-planted clumping grasses, a hedge created from shrubs, a line of small trees or espaliered fruit trees, or a cascade of tendrils and flowers from a climbing vine – to name just a few possibilities.
Why choose a living fence? No matter how small your property, if there is room for a fence then there is probably room for a living fence. Well-kept living fences are extremely beautiful. Evergreen plants provide a verdant wall to look at all year round. Climbing plants with flowers provide colour, interest and architectural shapes to admire. A living fence is an extension of your garden, allowing you to layer greenery to create depth and texture. And if you already have a standard fence, you can breathe life into it with a climbing plant.
Cooling microclimates While living fences add a great deal of beauty, they can also help green our cities and create cool microclimates. Built-up urban areas are prone to the urban heat island effect: dense concentrations of pavement, buildings and other thermal mass surfaces absorb daytime heat, releasing it again at night. As a result, ambient temperatures can increase by one to three degrees Celsius. Greening infrastructure projects large and small, including living fences, can help counter this effect through the plants’ natural transpiration.
How to choose plants for a living fence When deciding on the style and plant selection for your living fence, consider its purpose, maintenance requirements, and how it will fit into your existing garden. Whether you opt for native or non-native species, always ensure you avoid species considered invasive in your area. Be careful
that your living fence does not impede communal walking paths, and consider traffic sightlines where necessary – especially for cars exiting driveways.
Grasses If your main priority is boundary marking, a living fence can be as simple as planting a row of ornamental grasses. There are many choices: Poa labillardierei (Common Tussock-grass) Pennisetum alopecuroides (Chinese Fountain grass), Lomandra hystrix (Green Mat-rush,) Miscanthus sinensis (Chinese Silver grass), Schizachyrium scoparium (Little Bluestem) to name but a few. Be sure to choose perennial grasses that will live year after year, either evergreen or grasses that will dry to a sandy or copper colour, marking the changing seasons. Some grasses have spiky foliage or sharp edges hence consider their appropriateness. Grasses can be cut back in late winter or left uncut for a few years. When cut back they reappear as vibrant green tufts in spring.
Shrubs Privacy and safety for children and pets can be achieved with shrubs planted to make hedges (though note that hedges need dense foliage or supplementing with a wire fence to reliably contain small pets). There are many shrubs to choose from, and garden nurseries offer plenty of information on the growing requirements of plants to help you make your selection. Look for plants in the following genuses Acacia, Westringia, Acmena, Yew, Thuja, and Laurel to name but a mere few. Search for plants that suit your soil type and climate, and be sure to check the height, width and growth rate. Fast-growing hedges will establish quickly but need more frequent pruning, watering and compost. Slower-growing hedges can take years to establish but will then need less maintenance. Also consider colour, foliage texture, and whether you’d prefer evergreen or deciduous. An evergreen shrub will stay green all year round, while deciduous species will change colour before (usually) dropping their leaves. For example, Berberis thunbergia (Japanese Barberry) is a deciduous shrub that goes from green to bright red foliage in autumn. For silver foliage try Westringia fruticose (Native Rosemary(, Teucrium fruticans Tree Garmander), or Pittosporum tenuifolium ‘Silver Sheen’ (Pittosporum Silver Sheen)
Trees A line of small trees can also be used to create a fence, or to green an existing fence line. A popular choice is any tree in the conifer family with a tall, narrow form; plant them as close as planting instructions will allow. For an ‘edible fence’, you can espalier fruit trees. Espaliering is easy to do, saves space and allows even small garden owners to access seasonal fruit. Buy bare-rooted trees and plant in winter, and explore the many instructional videos on different espaliering techniques available online.
Climbing vines Climbing vines on a structural support can form a fence for privacy and for containing animals and kids. Choose evergreen plants for year-round screening or deciduous ones for a flash of autumn red followed by bare branches. You can use metal mesh or tensioned wire on a structural frame or a
wooden fence to support your vines; remember that climbing plants are heavy once established so make sure the structure is able to support the weight. There are many fantastic climbing plants to choose from. The evergreen Hardenbergia violacea (Purple Coral Pea )produces a mass of gorgeous purple pea flowers. Pyrostegia venusta (Golden Shower) has stunning orange trumpet flowers and climbing tendrils. Trachelospermum jasminoides (Star Jasmine’s)’ sweet fragrance, Rosa banksiae’s (Lady Banks Rose) rose clusters and the tiny fairylike leaves of Muehlenbeckia complexa (Maidenhair Vine) are all attractive options. If your home or rental property has an existing brick or masonry fence then try Parthenocissus tricuspidata(Boston Ivy) with its burnt red autumn leaves, or Ficus pumila’s (Creeping Fig’s) attractive juvenile leaves.
Before planting Whether you opt for grasses, shrubs, trees or climbers for your living fence, do your plant research. How will the plant grow? How will it change over time? What level of maintenance will it need? Will it drop leaves? Might its root system cause any long-term problems? While it is good to be aware of these things, however, don’t get overwhelmed: generally the value of a living fence far outweighs its care needs. And one final piece of advice: if establishing a new fence, it’s a good idea to do a property boundary search via your relevant state agency to ensure you’re putting the fence in the right place and not on your neighbour’s property. Whether you live in a city, a regional town or in the bush, infrastructure like fences is often necessary. Likewise, rewilding our living environments is important, and easy to do. A living fence is a great way to combine the two, and the benefits will be experienced by you and all that pass by.
Farmers working plots as small as a third of an acre have agreed to implement permaculture techniques as part of a matched grant program around Begnas Lake in Nepal.
Hillside farms overlook Begnas Lake
With the Nepal Permaculture Group they are creating a local hub for a network of farmers who are cooperating to discover and demonstrate the advantages of organic farming.
In the 2018-19 grant round Permafund helped kick off a farm improvement project with a workshop for farmers in the Kashki district.
The main objectives of the workshop were to:
introduce people involved in permaculture and similar philosophies to the network and provide a forum for sharing their expertise and experience.
identify the skills in the networks of organic food marketing in Nepal
find ways to establish an organic produce & market network in Pokhara
build a local Resource Centre to promote permaculture and related philosophies
work as a pressure group to advocate and lobby for a more sustainable society.
The farmers produce fruit, vegetables, medicinal herbs and livestock
Beekeeping adds to the mix of produce
The farmers agreed to
continue to improve their farms for at least seven years while also receiving technical and other support from the state government,
coordinate and collaborate with other farmers in their areas,
keep records on costs and benefits to help analyse the difference between a conventional & a model farm
base their work on organic and permaculture principles
to report on their farm’s progress on a quarterly basis
to establish their farms as model farms in their area with at least two farms to be utilised as local resource centres.
The support from Permafund has helped the Nepal Permaculture Group coordinate the resource centre and model farm initiative which is encouraging and empowering farmers and inspiring their communities.
