Reading: The cut-flower industry in Tanzania

“Tanzania, like many other developing countries, is attempting to diversify its export base with a view to gaining new sources of income and foreign exchange and thus reducing its exposure to price volatility that typify international markets. A handful of non-traditional products such as oilseeds and oil, spices, fruits, vegetables and cocoa beans – which are almost invariably traded unprocessed – are beginning to contribute to total exports. Tanzania is strategically located between 1° and 12° south of the equator, thus commanding an enviable tropical climate to accommodate the production of a wide range of fruits, vegetables, spices, and flowers, both tropical and temperate. Some of the crops can be produced throughout the year and the majority are highly seasonal, consumed at farm level with a potential for local and export markets.”

“Flower-growing in Tanzania is a new activity practised in the northern zone, mainly in Arusha and Kilimanjaro regions where the climate is favourable and an export gateway available through Kilimanjaro International Airport (KIA). Being an agricultural activity, flower growing has the advantage of being a natural adjunct to more traditional exports, while the availability of ready markets in developed countries provides powerful financial incentives.”

cultivation of cut flower/foliage such as Carnations, Euphorbia and Ami Majus”

The location of all the surveyed farms in Arusha region owes itself to the region’s favourable climatic conditions and to the proximity of the Kilimanjaro and Jomo Kenyatta international airports.”

“Drip irrigation is the system most commonly used, being the most efficient available. Six farms used drip irrigation while the remaining two used overhead sprinklers. The sources of water are boreholes, springs and rivers such as Usa and Nduruma.”

Only 26 per cent of the total costs involved in flower production for the past five years were investment costs. This is because most of the items in this category are fixed costs, e.g. land and the infrastructure were investment costs. Greenhouse construction is the costliest investment, accounting for 50 per cent of the total, mostly because construction materials have to be imported. Land accounts for 17 per cent of the total costs followed by planting materials (12.3 per cent). Office equipment costs are the lowest (0.3 per cent). This is due to the fact that most farms maintain small offices without much equipment.

The African landscape is more vast than the diversity of its peoples, languages and cultures. Native plants of Africa traverse tropical, savanna, desert and high-mountain subarctic regions, and the abundance of plants in the tropical rain forest regions of Africa plays an important role in the amount of oxygen available in the world’s atmosphere. There are many native plant species of Africa used around the world for their decorative beauty, food and non-edible products.

African Violet

A delicate flowering plant that has graced many homes around the world, the African violet (Saintpaulia varieties) is native to the Nguru Mountains area in the central East African country of Tanzania. The African violet’s blossoms bear a close resemblance to violet flowers, varying in colors ranging from white to purple. Its leaves have fine, furry surfaces and round or oval shapes.


The common names of this plant, which belongs to the same family as cotton, hibiscus and cocoa, include lady fingers, gumbo, quingumbo, bamyah, kopi arab and bhindi. Okra plants (Abelmoschus esculentus) are both annual and perennial depending on the variety, and they produce flowers that greatly resemble white hibiscus flowers prior to their fruit-bearing phase. The edible okra pods and leaves are prepared in a variety of vegetable and meat dishes around the world. Its seeds are also roasted and prepared as a coffee substitute.


Native to the Sudan and cultivated in tropical areas around the world, tamarind (Tamarindus indica L.) is a tree that bears sweet and sour fruits that tantalize the taste buds of those who like a natural yet tasty kick. The tamarind tree grows to heights of 100 feet, bearing evergreen leaves and brown elongated fruit pods. Inside each pod is a collection of brown, shiny seeds covered in a tangy, edible fruit pulp eaten raw or used in chutneys and culinary recipes.


Kiwano (Cucumis metuliferus) is native to the central and southern countries of Africa. Also known as African Horned Cucumber, Hedged Gourd and Horned Melon, Kiwano is a vine of the melon family that produces fruit with a spiked appearance. Although Kiwano is cultivated and exported for its decorative appearance, the fruit itself is long-lasting and very nutritious.

Bermuda Grass

Although its namesake comes from the Bermuda Island, Bermuda grass (Cynodon dactylon) is native to Africa. It grows in dense, creeping clusters close to the ground, producing deep root systems that make the grass highly drought-tolerant. Some other names of Bermuda grass include wire grass, dogtooth grass and couch grass.

Reading: Indigenous Vegetables in Tanzania, Significance and Prospects

African indigenous vegetables play a highly significant role in food security of the underprivileged in both urban and rural settings (Schippers, 1997). They can serve as primary foods or secondary condiments to dishes prepared from domesticated varieties. They are also valuable sources of energy and micronutrients in the diets of isolated communities (Grivetti and Ogle, 2000). Further, they may serve as income sources and may be marketed or traded locally, regionally, even internationally, and the primary importance of edible wild species during periods of drought and or social unrest or war is well documented (Humphry et al., 1993, Smith et al., 1995, Smith et al., 1996). However, the important role of African indigenous vegetables in Tanzania’s health sector, diets and as an income source is threatened through extinction of the genetic resources of these species. Many landraces of vegetables are in the process of being replaced by modern varieties (FAO, 1998). (Weinberger and Myusa, pg. 11)

Of the three target vegetables, amaranth had the highest Fe contents (up to 37.05 mg per 100 g of edible portion) followed by African nightshade (up to 15.90 mg)(Table 3.1). The African eggplant has the lowest contents of Fe (being as low as 2 mg per 100 g of the edible portion). (Weinberger and Myusa, pg. 18)

Although many health and nutrition workers in Tanzania have paid much attention on promoting consumption of ‘imported’ vegetables such as spinach, when it comes to using a food-based approach for combating dietary anemia, they may need to rethink and focus more on some of these indigenous vegetables. For example, while the iron contents of spinach (Spinacia oleracea) found in most parts of Africa is known to be 1.7 mg per 100 g edible portion (FAO, 2004), the values observed in this study for amaranth and nightshade are as high as 37 mg. Other noted good sources of iron include spiderflower plant and hairy lettuce (up to about 50 mg per 100 g of edible portion). (Weinberger and Myusa, pg. 23)

Buying IV crops is much more important during the dry season, when approximately two-thirds of all households purchase IV crops at the market. During the rainy season hardly any household buys IV crops since vegetables are either found and collected outside the homestead or produced in home gardens during that period. In Kongwa and Singida one-third of households never buy IV on the market (Table 4.9). The crops most frequently purchased on the market, listed in order, are amaranth (67% of all households), okra (37%), African eggplant (33%), nightshade (25%) and sweet potato leaves (23%). Amaranth is by far the most popular crop to be purchased on markets, and this is true for all districts (Table 4.10). Exotic vegetables are more often purchased at the market than IV crops, which are more often produced at home (Weinberger and Myusa, pg. 32)

Indigenous vegetables are important both for consumption and production, and in both cases, poor households rely more on these vegetables than more wealthy households. However, in comparison to older literature, the importance of IVs for consumption appears to have declined over the years. For poor households, the value of IV consumption is approximately 11% of the value of all food consumption, compared to 2% for the wealthiest households. Indigenous vegetables contribute significantly to the consumption of micronutrients, particularly of poor households, where approximately half of vitamin A and one-third of iron requirements are consumed through IVs.
Approximately 40% of farmers who cultivate small plots of land are engaged in the cultivation of IVs, while only 25% of relatively largescale farmers are engaged in the cultivation of IVs. The share of both marketed and non-marketed indigenous vegetables in total household income is, on average, nearly 13%. Indigenous vegetables thus contribute significantly to overall household incomes. It would be wrong to believe, though, that IVs are a purely subsistence crop. Several IVs are highly commercialized, and some of them can nowadays be found in supermarkets and convenience stores. Thus it appears that there is a good market potential for these crops, both in the high-price segment, as well as in the low-price segment.

A willingness-to-pay analysis among urban consumers indicated there is considerable scope for price increases. On average, consumers were willing to pay an additional 34% for amaranth to 23% for African eggplant. Commercial seed companies are also recognizing this potential and are entering—albeit cautiously—the market of IV crop seeds. (Weinberger and Myusa, pg. 64)

Mind Meets Paper

Thesis Update

Ali Price

Thesis Studio

Spring 2011



Original Thesis Statement:


The intent is to use architecture to cultivate social growth, opportunity, and prosperity. I propose an architectural process that achieves this by involving the community (people and culture) of Arusha, Tanzania in the design process, construction phase, and continually through the activities and relationships that exist in and around the built structures.



New Focus:


The intent is to use architecture to cultivate social growth through program and design. I propose to explore the program to establish an efficient prototype then test it on Arusha, Tanzania by infusing culture, collaboration, and most importantly cultivation.


Exploration of the program will consist of research of tested and theoretical prototypes. Four levels will be defined: shipped containers, kit-o-parts, mixed, built on site. Finding the appropriate adaptation of the prototypes will have to allow for cultivation to transcend into the construction. To emphasize the importance of the community, the prototype will be adjusted to allow for the infusion of people and their environment into the plan. Construction methods will be able to be performed by community members and materiality will reflect its environment.



Key Terms to Explore: community, culture, environment, sustainability, adaptability, polyvance, prototype, social growth, component, linkage, infuse, connector, catalyst


Programs Three Cultivators: dwelling, healing, and learning with social implications connecting the three programs.


Element that Melds Program with Site: Cultivation (people, climate, topography, culture, activities, etc)

This website shows a steel shipping container that has been turned into an internet cafe. It speaks of it;s connectivity as well as efficiency. This is located in Arusha, Tanzania.


“I was really impressed with the finish work in these units. To be honest, when I first heard I’d be shooting internet cafés built from converted steel shopping containers, I didn’t have very high expectations. I love the prefab structure idea, but a shipping container?! That can’t be good. But I was so wrong! These have insulated and sheet-rocked walls, recessed halogen overhead lighting, air conditioning, comfortable chairs and of course wickedly fast and reliable 3G internet connections. One savvy entrepreneur in Arusha even made room for a small Pepsi branded refrigerator that he sold cold soft drinks from. Brilliant!”




This website shows a plan prototype that has been adjusted to accommodate a community in South Africa.


“Through the use of legos as a visualization tool students were able to communicate their feelings about hospitals and schools in their communities.  I identified a need for a sense of security, cultural pride and eradication of the impersonal hospital environment as important principles to incorporate into a new building prototype.”


“Presently the conceptual design will be used as a tool to help Zimisele fundraise for their community programs and building fund.  Through the use of local building materials and methods the construction of the building can generate job opportunities for Umlazi residents”




The project above is a competition winner that utilizes containers for the architecture’s structure and is filled with sustainable contraptions such as water tanks and other essential “western” supplies. The process is one of many phases (phases integration). During this process the containers are adjusted to suit the vernacular (mimicking assembly and aesthetics) then is applied with different tactics to fight against the spread of AIDS through schools, community centers, and clinics.

Reading: Boutin’s review on Roger Riewe

“The simple is not simply simple. Roger Riewe.”

“The architecture of Riegler Riewe is strategically positioned in contemporary practice between a modernist exclusivity and a post-modern inclusivity. The advocacy of concepts that are limited to the essential, the economical, and the realizable, while defining function as the point of departure in the projection of minimal forms, reflects modernist sensibilities.” (Boutin)

“These concerns contrast sharply with Riegler Riewe’s insistence on elevating process over product in an effort to deny the consumption of the building, a specifically postmodern intention that was well represented in the work of Peter Eisenman and Bernard Tschumi amongst others.” (Boutin)

“It is a redefinition that shifts an objective, exclusive, and defined paradigm, to an open-ended, evocative and inclusive paradigm – the creation of an architecture of conditioned openness. Where function implied the definition of an empirical purpose, utilization suggests a broader palette of occupation, an understanding that a building frames not only the performance of specific functions, but the manner in which the totality of human life unfolds in these endeavours. It is the unpredictability of this unfolding and its evolution over time that Riegler Riewe address through the generosity of a spatial freedom facilitated by minimum means” (Boutin).

“In explaining the relationship between use, abstraction and form, Riewe states: “…we are interested in the display of utilization– in an open structure, which inevitably results in an abstraction of spatial and organizational dispositions.”[2] In this way, utilization as content, interpreted through abstraction, becomes the means to spatial fluidity and flexibility, dictating not a precise function, but a framing of the present and future potentials of that architecture” (Boutin).

“Here, as in the other examples of postmodern practice, the intentions of the architecture is to construct, in this case, constructing place through the careful definition of particular relationships between site and artefact. The central argument in Riewe’s theory of place to space is the provision of not a single and idealized conception of place defined by the architect, but of numerous and different potentials of place, defined by its occupation and the forces already present in the site” (Boutin).

“ARR’s strategy is of a non-prescription of space and form that allows the inhabitants to take possession of their building, initiating a process of continual evolution between architecture and user” (Boutin).

“Riewe insists that the development of the construction details and the selection of materials are the extension of the same design process. Specifically, he recognizes that the exploration into the details must commence during the analysis of the utilization, imbuing the design of the detail with the same conceptual questioning, thereby “…integrating it into the context of the task to be solved” (Boutin).

“That these new relationships between the building occupant and their architecture create an initial level of friction is confessed by Riewe. However, he also suggests that: “A phase of irritation due to abstraction can well lead to a strong identification with the project.” (Boutin)

Reading: Heidegger’s “Building, Dwelling, Thinking”

“… when to dwell means merely that we take shelter in them” (Heidegger 100)

“What, then, does Bauen building, mean? The Old English and High German word for building, buan means to dwell. This signifies; to remain, to stay in place. The real meaning of the verb, bauen, namely, to dwell, has been lost to us” (Heidegger 100).

“When we speak of dwelling we usually think of an activity that man performs alongside many other activities. We work here and dwell there. We do not merely dwell – that would be virtual inactivity” (Heidegger 100).

“The old word bauen says that man is insofar as he dwells, this word bauen however also means at the same time to cherish and protect, to preserve and care for, specifically to till the soil,, to cultivate the vine. Such building only takes care – it tends the growth that ripens into its fruit of its own accord” (Heidegger 101).

“Here building, in contrast with cultivating,is a constructing. Both modes of building – building as cultivating, Latin colere, cultura, and building, that is dwelling as the raising up of edifices, aedifiare – are comprised within genuine building, that is, dwelling” (Heidegger 101).

“1) Building is really dwelling. 2) Dwelling is the manner in which mortals are on the earth. 3) Building as dwelling unfolds into the building that cultivates growing things and the building that erects buildings” (Heidegger 102).

“Gathering or assembly, by an ancient word of our language, is called ‘thing’. The bridge is a thing – and indeed, it is such as the gathering of the fourfold” (Heidegger 104).

“Things which, as locations, allow a site we now in anticipation call buildings. They are also called because they are made by a process of building construction. Of what sort this making – building – must be, however, we find out only after we have first given thought to the nature of those things which of themselves require building as the process by which they are made. These things are locations that allow a site for the fourfold, a site that in each case provides space” (Heidegger 105).

“Yet space is not something that faces man. It is neither an external object nor an inner experience” (Heidegger 106).

“Building puts up locations that make space and a site for the fourfold. From the simple oneness in which earth and sky, divinities and mortals belong together, building receives the directive for its erecting of locations” (Heidegger 107).

“For his cultivates the growing things of the earth and takes care of his increase. Cultivating and caring are a kind of building. But man not only cultivates what produces growth out of itself; he also builds in the sense of aedificare, by erecting things that cannot come into being and subsist by growing. Things that are built in this sense include not only buildings but all the works made by man’s hands and through his arrangements” (Heidegger 112).

“Building in the sense of the farmer’s cultivation of growing things, and of erecting edifices and works and the production of tools, is already a consequence of the nature of dwelling, but it is not its ground, let alone its grounding. This grounding must take place in a different building” (Heidegger 112).

Reading: Turner’s “Housing by People: towards Autonomy in Building Environments”

“This confusion and consequent error can only be avoided by recognizing the different meanings of ‘housing’ and ‘value’ and by using them properly. Market values are, of course, different from human values” (Turner 64).

“In English the word ‘housing’ means both the stock of swelling units (a noun) and the process by which that stock is created and maintained (a verb)” (Turner 64).

“Housing must, therefore, be used as a verb rather than as a noun- as a process that subsumes products. Real values are those that lie in the relationships between the elements of housing action – between the actors, their activities and their achievements” (Turner 66).

“Quantitative methods cannot describe the relationships between things, people and nature – which is just where experience and human values lie. They may be essential for determining resource allocation, and as aids in identifying complex systems and their components, but quantitative methods can only indicate, not measure, non-quantifiable components – the human realities of housing” (Turner 66).

“as a subsystem of the large system or systems of which it can been seen as a part. Any subject matter of value must have three elements: people, the things they do, and the relationships between the two. Or, as Geddes expressed it: organism – function – environment (where function is the relationship and oth organism and environment are acting on each other). In the simplist useful terms, any specific housing process can be described as the interaction of the people (or actors) and their products (or achievements) through the medium of their roles and responsibilities (or activities)” (Turner 70).
