Evaluation of hotboxes in rural and peri‐urban areas∗

A hotbox, or wonderbox as it is commonly known, is a simple time, energy and money saving device for cooking. The objective of this study was to evaluate the impact of wonderboxes on cooking patterns and household energy consumption in rural and peri— urban areas, and to make recommendations about the design of wonderboxes and about dissemination strategies. The research consisted mainly of questionnaires and interviews. In addition, practical experience was obtained in establishing a small wonderbox‐making enterprise.

The fuel most commonly used in conjunction with a wonderbox is paraffin, and in some cases possession of a wonderbox facilitated the transition from firewood to paraffin. There is little doubt that wonderboxes reduce energy consumption, but data on energy savings are inconsistent. It appears, however, that a wonderbox will recover its cost (usually about R12 in 1987) in less than six months.

While users of wonderboxes are appreciative of their fuel‐saving capabilities, the primary motivation in buying a wonderbox is usually convenience, time‐saving and the ability to leave food cooking while away at work. In fact, there were three times as many women in paid employment in the sample of wonderbox users, compared to non‐users.

Wonderboxes are apparently not perceived as being an inferior technology, which is often a problem with appropriate technology. They are rather seen in the context of advancement the transition from subsistence to wage employment, from noncommercial to commercial fuels, from drudgery to time‐saving. In promoting wonderboxes, this perception should be given as much or more emphasis than energy‐saving, and the drab appearance of the box should be changed.

While possession of a wonderbox has sometimes introduced changes in the pattern of food preparation and fuel use, it does not impose an inflexible and unfamiliar domestic regime on the household, which might have made wonderboxes unacceptable.

Many people are unaware of wonderboxes and their advantages, and this lack of knowledge is a constraint on dissemination. However, it is suggested in this report that the most serious constraint is that wonderboxes are unavailable except through a few, mainly non‐commercial, outlets. Two possible solutions to the problem of distribution should be investigated. The first is to make use of existing wholesale and retail networks. The second is the establishment of several small scattered wonderbox‐making enterprises in rural and peri‐urban areas, assisted by a central service organisation.     

The role of dryland cotton as a source of household income in two magisterial districts of KwaZulu

The aim of this paper is to illuminate certain economic aspects of the production of dryland cotton among rural households in the Ubombo and Hlabisa magisterial districts of KwaZulu. In order to assess the viability of the household cotton enterprise, its contribution to household income and the producers' perceived constraints to production, an interview survey was conducted among 100 cotton‐adopting households in the two study areas. Multi‐stage sampling techniques were employed to facilitate the study.

Results show that the Ubombo region's inherent climatic suitability, combined with extensive support services, has benefited the dryland producer and resulted in a lucrative on‐farm enterprise. Cotton contributed an average of 62 per cent to annual household income in this district

In the climatically less suitable Hlablsa district, where producers are limited by lack of finance and small land sizes, wage labour was found to be the prime source of cash income for the household, while cotton contributed an average of 17 per cent towards annual household income.

Producers in both areas are cost effective relative to the white commercial farmer while mean yields and net incomes indicate that dryland cotton has the potential to contribute much to the development of certain areas of KwaZulu. Overspending on chemicals may indicate the need for increased extension into complex pest control management procedures.     

Farm household economics: Some policy implications for emergent farmers in Southern Africa

Farm household economics recognises the fact that production and consumption decisions are made jointly by small farm (ie surplus‐producing) households. This phenomenon is of particular importance in areas where small farm households predominate.

Most empirical applications of farm household economics have been directed at measuring the effects of price changes on consumption and have relied on the ‘separable’ approach in deriving estimates. This approach assumes that production decisions always precede consumption decisions with farm households treated as profit maximizers in production and utility maximizers in consumption. Results have clearly demonstrated consumption responses smaller than estimates based on consumer theory alone.

Although many researchers regard mathematical programming as a potentially suitable tool for simulating smallholder behaviour, proponents of new household economics would be reluctant to accept any model that does not (a) maximize utility (rather than profit) and (b) capture the ‘profit effect’ which variations in product prices have on the farm household's full‐income constraint. Attempts to include these basic postulates of farm household economics in programming models are in progress.     

Socio‐economic factors determining the success achieved among cotton‐adopting households in two magisterial districts of KwaZulu

The aim of the paper is to investigate certain aspects of the post‐adoption behaviour of dryland cotton farmers in the Ubombo and Hlabisa magisterial districts of KwaZulu. Particular attention is paid to the socio‐economic determinants of the success (returns per hectare) of the household cotton enterprise.

Multi‐stage sampling methods were used to draw a random sample of fifty cotton‐farming households from each of the two study districts. The data were collected by interview survey and analysed using principal components and regression techniques.

Results suggest that the success of the household enterprise in both areas is largely determined by the socio‐economic environment under which the producer operates. The most important success‐determining factors are those relating to the human capital endowments and economic status of the household.     

Ecology and development

There is an increasing realization, world‐wide and in Southern Africa, that conservation and development are compatible.

Because human communities in the less developed rural areas are dependent on a renewable group of resources, including soil, water and forests, it is imperative that land use systems that protect these resources are introduced.

The predominance of subsistence agriculture in these areas is the most difficult syndrome of under‐development. An overall rural development strategy is required that integrates human development with resources management Where the population carrying capacity of the land has already been exceeded, a process of rapid villagization/urbanization is required. Village/urban growth and agricultural development require a carefully co‐ordinated programme of land capability analysis and planning, as well as active investment in infrastructure and the introduction of appropriate technologies and institutions.     

Towards adequate and equitable energy provision for farmworker families

Consumption patterns of farmworker households are constrained by limited access and choice. Few households use electricity to any significant extent, most rely on fuelwood for power‐intensive energy applications, and the use of commercial hydrocarbon fuels is generally lower than in other rural communities. An evaluation of energy supply reveals opportunities for improvement, particularly for households on farms with a grid electricity supply and with the potential for fuelwood production. First, problems must be overcome, most of which result from the socio‐economic status of farmworkers and their dependence on their employers.     

Regional development effects of a free market for sugar in South Africa

In a free market for sugar it is estimated that the area under sugar‐cane would decrease by 49 per cent and labour employment by 26 per cent relative to the single‐price policy which was in operation until 30 April 1985. Sugar‐cane would be produced in areas of comparative advantage, namely the Eastern Transvaal, Zululand high and low rainfall areas, the North Coast, Indian and Mangete areas and KwaZulu. The domestic equilibrium sucrose price is estimated to be about 9 per cent below the price under the single‐price policy and 17 per cent below the A‐pool producers’ price under the present two‐tier price scheme.

Full irrigation water tariffs have a considerable impact on enterprise mix. Farmers would shift from sugar‐cane to higher return crops or leave land fallow if they perceived the risk to be too high. Land values would fall in irrigation areas and increase in dryland areas.

Results are obtained from a regional linear programming model which incorporates negative sloping demand functions for crops, limited substitution in demand between crops, positive sloping labour supply functions and variance/ covariance risk matrices.     

Inefficient land use in KwaZulu: Causes and remedies

Rural KwaZulu is a less developed region of South Africa. Despite intense population pressure, arable land is underutilized. Grazing resources are overutilized.

Supply response to price incentives and farmer support programmes is inelastic as the potential gains to farmers are limited by small farm sizes. Facilitating the land rental market could improve efficiency informing, and also has equity advantages. Institutional changes are needed to encourage land rental

Overstocking occurs primarily because grazing is an open access common property resource. Unlike most solutions to overstocking (eg cattle taxes and quotas), privatization of grazing land (even in the limited sense that arable land is privately controlled) would not only encourage stock‐owners to reduce stocking rates but would also improve their incentive to upgrade herd and pasture quality. It is recommended that privatization be promoted in areas where it is more acceptable to households.     

The role of off-farm employment in the rural energy consumption transition — A village-level analysis in Jiangxi Province, China

Energy consumption in rural areas in China is characterized by high consumption of fuelwood, straw and other biomass. Off-farm employment can play an important role in the transition towards more sustainable sources of energy by increasing rural household incomes and reducing the amount of labor available for biomass collection. The purpose of this paper is to examine the impact of off-farm employment on rural household energy consumption choices, and to disentangle the various causal relationships that play a role in this respect. To this end, a hybrid farm household/village computable general equilibrium (CGE) model is used that has been calibrated for a remote village in Northeast Jiangxi Province where fuelwood is the main source of energy. The model takes into account nonseparability of farm household production and consumption decisions as well as linkages within the village between households involved in off-farm employment and households with no members working off-farm. Contrary to previous research for a richer region in rural China, we find that fuelwood is not an inferior good. The positive impact of more food consumption on fuelwood collection more than compensates the higher leisure demand associated with higher incomes. Shifts in production activities and in prices on village factor markets caused by increased labour scarcity (the lost-labour effect of off-farm employment), on the other hand, cause a reduction in fuelwood collection and consumption. This lost-labour effect is much stronger for migration than for local off-farm employment, because the latter can more easily be combined with on-farm work and fuelwood collection. For local off-farm employment the income effect dominates the lost-labour effect, resulting in a positive overall impact of higher off-farm participation on fuelwood consumption. For migration, on the other hand, the income effect and the lost-labour effect are almost equal in size. Hence, the amount of fuelwood collected and consumed does not change much when households participate in migration. The final conclusion is therefore that increased off-farm employment opportunities do not promote the transition of rural energy use in the poorer regions of rural China.     

The effect of HIV on health care in sub‐Saharan Africa

This article is concerned with the hitherto neglected area of the effect of HIV on the delivery of health care in sub‐Saharan Africa. The task is hampered by a lack of usable data. In most countries there have been no sentinel HIV surveys, so we have no clear idea of the magnitude of the epidemic. However, it is certain that HIV will alter the demand for health care, and the supply and quality of services.

Demand will grow as infected adults and children seek care. Most HIV‐related illness is found in people who would not normally require care, and therefore creates additional demand. Demand for care will also be determined by the availability and accessibility of services. Ironically, the middle‐income countries may face higher bills, and in this sense the effect of the HIV epidemic may be worse in the more developed world.

The supply of services will be affected by increased morbidity and mortality among health care workers. This is already happening. The generous terms and conditions of service that most governments offer to workers in the public sector will make the problem worse.

HIV has served to improve the quality of health care in most of the developed world. Patients have sought to take control over their own care, and staff have been more rigorous in taking universal precautions. But in developing countries external aid often determines how health care is organised, and money spent on AIDS is diverted from other areas. This may also be true of local funding.

The effect of HIV on health care is lamentably under‐researched. This is particularly worrying as the effects of HIV will be felt first by the health care sector. The problem must be confronted urgently from the point of view of the suppliers of health care services, the users, and the policy‐makers.     

Sources of capital and income for communal area farmers in Kavango: Implications for agriculture and rural development

A survey based on a structured questionnaire was conducted at the beginning of 1995 to identify sources of capital and income for rural households in Kavango. The survey, which covered 80 households, revealed that there was a high dependence on external income sources. Pensions were the major source of income for the highest proportion of all households (33 per cent), followed by wages (23 per cent) and brewing (10 per cent). Other sources of income of similar importance to brewing were crop sales, non‐formal work and cash remittances.

Livestock were a minor source of income but a major source of capital and food security. Households with smaller cattle herds depended more on cattle for income and food security than those with larger herds. Cattle were a highly valued production resource that was only consumed during times of crisis and only in the absence of less valuable assets that could be easily liquidated. Grain storage was more popular among groups with the lowest income. By various criteria, female‐headed households always tended to be in the group of households categorised as the poorest of the poor. However, given sufficient income, over one third of them would purchase cattle to diversify their investment portfolio.

This article presents a number of potential strategies for improving the incomes of rural households in Kavango. These include the promotion of equitable livestock ownership and better use of the grazing resource through community management, intensification of cropping and the implementation of labour‐intensive programmes to develop rural infrastructure.     

An overview of agricultural and rural development problems in less developed areas of Southern Africa

The problems discussed in this paper are essentially the influence of various factors which underlie the present low levels of agricultural production and the constraints to development of the less developed rural areas of Southern Africa.

The nature, intensity and output of small‐scale farming systems are dependent upon the interactions between and within five groups of factors: physical and ecological; the agri‐milieu; institutional and operational; the human potential; and technology.

This paper discusses previous and present development trends, and reviews the interrelated problems of use of physical resources, the agri‐milieu, human resources, institutional problems and technology.

Suggestions are made for a co‐ordinated strategy at national and local level aimed at removing some of the present barriers and constraints to agricultural and rural development.

Income distribution,economic structure and employment in South Africa

This paper discusses the impact of a redistribution of current income from the White to the Black population on the distribution of sectoral output, and total employment by means of a semi‐closed input‐output model.

The results show that a redistribution of current income towards Black households — which no doubt will have positive social and political repercussions — has a non‐negative effect on GDP and a definite positive effect on the performance of sectors with a high private consumption expenditure component, as well as on total employment.     

An agricultural survey of subsistence farmers in the Nkandla district of KwaZulu∗

In 1986 and 1987, an agricultural survey was conducted among 70 subsistence farmers in the Nkandla district of KwaZulu. The aims of the survey were to describe the farming system, identify constraints to agricultural production and make recommendations for future extension work in the area.

No stock was sold in 1986/87. However, hides and meat obtained from slaughter and deaths may be valued at about R150,98 per household per annum. Poultry contributed R31,86 per household per annum. Veld has been irreversibly degraded in most of the study area, causing a major constraint to cattle production. However, short‐term in creases in poultry production are feasible.

Cropping enterprises were dominated by maize, which was planted on 81% of the total field area and contributed about R413,86 per annum to household income. The most limiting constraints to maize yield were poor soil fertility and the related presence of witchweed (Striga asiatica), poor weeding (probably at the early post‐emergent stage of maize), late planting (after November) and the use of traditional seed. Steep slopes seri ously limit agronomic development. The introduction of timber and fruit trees may be feasible but other perennial crops are not viable in light of available markets.     

Collective forest tenure reform and household energy consumption: A case study in Yunnan Province,China

The recent Collective Forest Tenure Reform in China has started the process of devolving forest management rights from village collectives to households since 2003. In this paper, we study the impact of the reform on rural energy consumption. Devolving forest tenure improves farmers' access to forest products on their newly acquired forestland, and is therefore expected to increase farmers' fuelwood consumption. The reform also allows farmers to adopt some revenue-enhancing forest technologies which may lead to energy switching in farmer households. Our empirical study finds that the devolution significantly increases household fuelwood consumption for both lower and higher income households; the lower income households benefit more. This is welfare-improving in places where alternative fuels are still too costly. We find limited evidence that higher income households in Yunnan begin to substitute alternative commercial fuels for fuelwood when those are available. Our findings suggest further devolution of forest rights, especially in the poor, forest-rich regions.     

The promotion of maize fertiliser packages: A cause of household food insecurity and peasant impoverishment in high rainfall areas of Zimbabwe

Child malnutrition is a continuing problem in Zimbabwe's communal areas. These include some high rainfall areas, which make a contribution to the country's maize surplus during non‐drought years. A survey of farmers and extension workers in four high rainfall communal areas was carried out to investigate the effects of following recommended practices for maize production on household economy and food security.

Thirty‐two per cent of communal farmers had applied all the officially recommended fertiliser to their 1990/91 maize crop, often by obtaining these inputs on credit in lieu of grain sales receipts from the subsequent harvest. Yet. yields were so low that 48 per cent of these farmers would have been unable to retain sufficient grain to satisfy their families’ minimum requirements, if they had reimbursed the full cost of the input credit.

The majority (64 per cent) of farmers had deviatedfrom the recommended practice by adopting ‘low external input strategies’. A key feature of most of these strategies was the substitution of manure for part or all of the recommended fertiliser. In three of the four communal areas studied, this had improved the chances not only of recovering input costs, but also of achieving maize self‐sufficiency.

These results suggest that policy‐makers should shift emphasis from a dependence on costly external inputs to the integration of low levels of fertiliser with a range of more natural methods of soil improvement, in an effort to improve household food security in the communal areas.     

From Linear Fuel Switching to Multiple Cooking Strategies: A Critique and Alternative to the Energy Ladder Model

Promoting sustainable development requires evaluating the technical and policy options that will facilitate the adoption and use of energy efficient and less polluting cooking stoves and practices. The transition from traditional to modern fuels and devices has been explained by the “energy ladder” model that suggests that with increasing affluence, a progression is expected from traditional biomass fuels to more advanced and less polluting fuels. In this paper we evaluate the energy ladder model utilizing data from a four-year (1992–96) case study of a village in Mexico and from a large-scale survey from four states of Mexico. We show that an alternate “multiple fuel” model of stove and fuel management based on the observed pattern of household accumulation of energy options, rather than the simple progression depicted in the traditional energy ladder scenario, more accurately depicts cooking fuel use patterns in rural households. The “multiple fuel” model integrates four factors demonstrated to be essential in household decision making under conditions of resource scarcity or uncertainty: (a) economics of fuel and stove type and access conditions to fuels, (b) technical characteristics of cookstoves and cooking practices; (c) cultural preferences; and (d) health impacts. This model also allows better estimates of the expected fuelwood demand and indoor air pollution in rural households.     

What can economists do with South Africa's SAMs?

The South African Central Economic Advisory Service has recently published a report containing social accounting matrices for the economy as a whole, and for eight planning regions. This article provides a critical evaluation of these SAMs.

The Black states are includes in the SAMs, and the national SAM identifies seven income categories, four race groups, and ten occupational categories. Interindustry transactions are portrayed in a twenty‐four sector inter‐industry matrix. The regional SAM includes an analysis of racial incomes, and interregional flows of transfers from households, and trade and government transfers. A paradoxical result is that African migrant workers, who often hold the lowest occupations, appear in the top decile of the distribution of African incomes in the national SAM. The SAMs do not identify rural households, African households, in the rapidly growing fringe settlements around the metropolitan regions, and informal sector activities, and the article argues that these SAMs provide a snapshot of the economy which is severely out of focus.

The SAMs are based on a 1978 input‐output table and 1980 expenditure patterns. Since then changes in wage levels, the strength of Black unions, and the exchange rate of the Rand may have caused significant alterations in certain coefficients in the economy, possibly making the SAMs unsuitable for modelling policy changes.
