POLICY CONCLUSIONS

The macro-economic effects of UPA are improved food security and lower food prices, some employ­ment, and contributions to related industries. Although the empirical evidence for these effects is patchy, there is strong anecdotal evidence to sup­port them.

There are demand-led opportunities for urban agri­culture and horticulture specialising in niche and other products, such as highly perishable produce, specialised livestock and fish, in cities where UPA is underdeveloped (Garnett, 1999). The demand-led opportunities need to be matched, however, by supply-led growth in more deprived areas, to encour­age equity of access and affordability between different social groups.

Local food purchasing policies in the statutory sec­tor (hospitals, prisons, schools, etc.) could provide a major impetus to the development of UPA given that a large proportion of all food consumed is through this sector. Price and/or quality advantages would be needed to enable justification by the relevant authorities.

The provision and reasonable pricing of land and water resources is essential to develop UPA in the city. Within a supportive framework, policies are needed to protect and improve the security of land tenure for urban farmers. In the UK, this could take the form of amending planning policy guidance (PPG) relating to allotments, fringe farms, and other urban spaces used for food production.

Planning regulations and guidance should take into account the needs of urban farmers to invest in refurbishing facilities, or in new ones, to develop processing, storage, and packaging facilities, thus enabling them to ‘add value’ to their products and improve their turnover and incomes.

As with other industries, UPA is dependent upon the city’s infrastructure including the transport sys­tem, public utilities such as water management systems, and other services including labour and produce markets. Such infrastructure, if it does not exist, may be expensive to provide and maintain. Policies should be developed to encourage small – scale, inexpensive systems designed to address the most critical weaknesses in a city’s capital. With relatively little investment, such systems can greatly increase urban farmers’ productivity and viability.

Regional, national, and international policy changes are needed to overcome structural barriers and dis­torted markets in the urban food supply system. Potential new entrants operating sustainable modes of production would be encouraged by the internali­sation of the external economic costs and benefits. Appropriate standards, incentives, subsidy, taxes, and regulations could be used to internalise external

costs and benefits and shift profitability in favour of sustainable practices and encourage a thriving local food industry within and around towns and cities. For example, a tax on aviation fuel would help reflect its real economic cost to society and give produce
grown closer to home an advantage, whilst a sub­sidy for organic production would reduce the exter­nal economic costs incurred by water companies and their customers, caused by having to cleanse water of pesticides and artificial fertilisers.

Case Study 9.1 City Harvest project in London, UK

Подпись: Figure 9.1 Sustain, an alliance of a number of public interest organisations in the UK, initiated the City Harvest pro­ject in 1998 to examine the nature of UPA in London, and to encourage its residents to grow food. The project followed from the Growing Food in Cities project which looked at the benefits of urban agriculture in the UK. City Harvest organised a local food festival to celebrate the range, quality, and diversity of food grown in or near London and researched the existing aspects of urban agriculture, and its potential to contribute to the food security and sustainability of London in the future.

The study found that London’s ‘ecological footprint’ is estimated to be 125 times the capital’s surface area with food accounting for around 40 per cent of this. London’s residents, visitors and workers, consume 2.4 million tonnes of food and produce 883 000 tonnes of organic waste per year. The food industry makes a sig­nificant contribution to London’s GDP (about $122 bil­lion) with around 11 per cent of all jobs found in the food sector, although most of the food consumed comes from rural districts and other countries.

Almost 10 per cent of Greater London’s area is farm land, of which 500 hectares are under fruit and vegetable cultivation, and there are around 30 000 active allotment holders and an estimated 1000 beekeepers. Overall, the area under commercial cultivation is continuing to decline due to development pressures, labour scarcity/high wage costs, a skewed system of Common Agricultural Policy subsidies, competition from imports, and planning restrictions. The main area for commercial cultivation is the Lea Valley region in North East London.

The Lea Valley region typifies a declining industri­alised horticulture. This once thriving area for food production has shrunk since the war and the industry now only covers an area of 120 hectares under glass. It has a high productivity, with 200 or so horticultural enterprises ranging in size from less than an acre to 20 acres, with production often automated and hydroponic. The enterprises sell produce nationally to wholesalers and supermarkets.

The remnants of commercial urban agriculture in London, such as the Lea Valley example, provide an opportunity to redevelop, modify, and diversify the industry towards a more sustainable system.

Conversion to organic, development of sustainable, social enterprises, and production for local London markets, such as farmer’s markets, restaurants, and co-ops, would utilise the existing infrastructure and change the mode of production. Barriers would have to be overcome to enable this, such as encouraging organic horticultural production through the CAP and government programmes, changing planning policy to discourage inappropriate developments on the urban fringe whilst allowing fragmentation of farms to create smaller, more diverse holdings, and internalis­ing the external costs so food prices reflect their true cost and make the sale of produce at local markets preferable.

Case Study 9.2 Phd thesis on the economic costs and impact of home gardening in Ouagadougou, Burkina Faso

 

Sibylle Gerstle of Basel University, Switzerland, studied the economic costs and the effects of home gardening in Ouagadougou, Burkina Faso. Completed in May 2001, Gerstle looked at both a whole popula­tion group and, as samples, home gardeners on three sites with differing social and economic structures. Within this, Gerstle also considered the possible links between the economic dimension of home gardening and the health status of home gardeners.

Burkina Faso is one of the poorest nations in the world with a Gross National Product per capita of only $240 and with an infant mortality rate of 210 per 1000 for the under fives. Burkina Faso’s capital, Ouagadougou, has a population of 750 000 and an average growth rate of 6.8 per cent. It has 48 home gardening sites varying in size and from season to season.

One result from Gerstle’s study was that in both the dry and rainy seasons, home gardeners had a lower average monthly income than their counterparts prac­ticing any activity other than home gardening. This finding is unusual because other studies in Africa (Zalle 1999 (Bamako), Sawio 1993 (Dar es Salaam), Egziabher 1994 (Addis Ababa), and Mougeot 1999 (Lome)) have found that urban farmers have a higher than average income. However, an indirect estimate for income calculated on the basis of prices obtained for vegetables, was higher than the directly estimated one for all three sites. Additionally, in all three sites, the average monthly income of households was higher in the dry season than the rainy season, and income var­ied considerably between sites due to factors including the quality of irrigation water and the crop patterns.

In the whole population group, more than half of the predictable expenditure was on food. In the rainy sea­son home gardening households had considerably lower expenditure on food than non-home gardening households, whilst in the dry season, home gardening households spent an equivalent amount on food as non-home gardening households. Hence, the contribution of home gardening to household food security and ‘fungible’ incomes was mainly confined to the rainy season, reflecting the importance of the

seasons and climatic factors to urban gardeners in Ouagadougou.

With respect to the health status of the population, the most common aliments were malaria, gastro-intestinal diseases and respiratory diseases. The study found that the average number of days of illness was equivalent in both home gardening and non-home gardening house­holds, and, surprisingly, there was no correlation between the health status of the population and their socio-economic status. Hence, the expected health risk related to home gardening was not found and the lower monthly expenditure, lower income, and a lower expen­diture coverage rate were not directly related to the health status of home gardeners.
