This paper presents results of research that investigates if long hours of work spent by children in fuel wood collection and water collection activities, hereafter referred to as resource (collection) work, are related to the probability that a child aged 6-14 will attend school. Possible endogeneity of resource work hours is corrected for, using two-stage conditional maximum likelihood estimation. Using data from a 1997-98 Malawi Integrated Household Survey (IHS) conducted by the National Statistics Office (NSO), the study finds that children are significantly involved in resource collection work and their probability of attending school decreases with increases in hours spent on this work. The study further shows that girls spend more hours on resource work and are more likely to be going to school while burdened by this work. Consequently, girls may find it difficult to progress well in school. However, girls are not necessarily less likely to be attending school. The results further show that presence of more women in a household is associated with a lower burden of resource work on children and a higher probability of children.s school attendance while that of men is not. Finally, the study shows that children from the most environmentally degraded districts of central and southern Malawi are less likely to attend school and few of them have progressed to secondary school compared to those from the north region districts.

The purpose of this paper has been to present quality-adjusted values for land in the United States and nine European countries using price and quantity data for 1990. Disregarding such differences in the quality-adjusted land input would generate biased estimates of the land input and thus of total factor productivity. Land quality adjustments could potentially be enhanced further with additional data on soil characteristics, climate, and other productivity-related characteristics.

In recent times the role played by women in rural development has been given an ever increasing attention, culminating in the insertion of specific measures in Agenda 2000. The EU programs for rural development aim to single out the factors handicapping the full participation of women to the public and economic life at the local level and to develop specific initiatives for this category. Aim of the present research was the evaluation of the effectiveness of the new EU policy guidelines in terms of occupation and/or additional income achieved by women in agriculture. The study analysed the main characteristics of the farm women in a local rural system in Calabria. As any rural system, the one that was considered is the result of the interlace between various governmental intervention (EU and national policies) and the physical, social and economic characteristics of a particular territory. The analysis regarded social characteristic, characteristics of the farm, organisation and management. In relation to the specific agricultural activities, they were analysed the main sociological factors affecting the motivations and the attitudes of the local farm women, the difficulties in conciliating job and family and the potential unexpressed and the ambitions unfulfilled and/or discouraged.

The EU dairy sector will be one of the most sensitive sectors to be affected by the outcome of the on-going negotiations for the new WTO round for agriculture. Nevertheless, if the Next WTO Round is going to be along the same lines as the Uruguay Round, the EU may be able to stay within the WTO commitments for export subsidy in the dairy sector without further reforms in the Common Agricultural Policy. Certainly, some minor reforms are needed to relieve the binding commitments for cheese and other milk products. The upcoming reform in the dairy sector under Agenda 2000 starting from year 2005 may help in reforming the dairy sector for the new round. In contrast, a steeper reduction in the export subsidy commitments compared to the Uruguay Round may cause problems for cheese and other milk products because the majority of exports in these products will have to be exported without any export subsidy. After enlargement, in particular with a steeper reduction formula, the EU may face troubles in the categories of butter, skim milk powder, cheese, and other milk products. The reforms under Agenda 2000 may not be sufficient because the difference between the EU internal market price and world market price is still too high for EU dairy products to allow unsubsidised exports to the world market. The EU internal market will have to absorb the dairy products intended for the export market. Consequently, the EU internal market for dairy products will be under pressure for further price reduction, and the EU world market share in dairy products will shrink.

This paper analyses the economics of biodiversity conservation in the context of a tropical forest ecosystem in India, where coffee is the main competitor for land use. Using primary data covering a cross-section of coffee growers, the study notes that the opportunity costs of biodiversity conservation in terms of coffee benefits foregone are quite high. Even after including external costs due to wild life damages and defensive expenditure to protect against wild life, the NPVs and IRRs from coffee for all land holding groups were high. Even if the expected benefits were to decrease by 20% and costs rise by a similar proportion, still the IRRs from coffee were quite high (19.5 to 20.1 per cent). The study notes that the external costs accounted for between 7 to 15 per cent of the total discounted costs of coffee cultivation, and smaller holdings proportionately incurred higher external costs as compared to large holdings. The study also notes high transaction costs incurred by the growers to claim compensation for wild life damages. Notwithstanding these disincentives, the study notes that the local community were willing to pay in terms of time for participatory biodiversity conservation, and they preferred a decentralized government institution for this purpose.

Most food products can be classified as ‘credence’ goods and regulations exist to provide consumers with a substitute for the lacking information and trust. The paper presents an analysis of the decisions of producers and consumers about a ‘credence’ good in three institutional scenarios, which reflect different levels of credibility of the regulation.

The first scenario is a reference scenario in which the regulation is fully credible. In the second case considered there is no regulation, or, if there is, it is totally ineffective. In the third scenario a regulation only partially credible provides consumers with an imperfect substitute for the information and trust they lack. Some of the producers of ‘low’ quality goods share with the producers of .high. quality goods an interest in the introduction of a regulation as long as this is not fully credible. In addition, it may be the case that even producers of ’low’ quality goods who know they will not be able to sell their products labeling them as being of ‘high’ quality may have an interest in supporting a not fully credible regulation. Finally, rather than having producers of ‘low’ quality goods ‘block’ the introduction of a fully credible regulation, producers of ‘high’ quality goods are better off when a compromise is reached which leads to the approval of an imperfect regulation.

Producers in industrialized countries have been inundated with ideas and information about precision agriculture (PA) and how new site-specific management (SSM) technologies will revolutionize their farm operations. Conjuring up Star Wars-imagery, farmers and their computerized machinery communicate with satellites while speeding up and down the information highway. The farm press has hailed the advent of these technologies as a win-win situation with higher farm profits and improved environmental quality. Certainly the potential is there for greater economic returns and better environmental stewardship. But what exactly is precision agriculture, who is applying it, and where? Is the technology only relevant for developed countries and are there implications for markets? What is the likelihood that environmental benefits will be realized?

This paper addresses these questions by drawing on literature, data, and expert opinion to explore what technologies have been developed and which ones have been or are likely to be adopted, by whom, and where. It considers the environmental implications of this host of new information technologies.

This contribution deals with opportunities to integrate ecological objectives into landscape modelling. We start with the behaviour of farmers. By depicting the behaviour of farmers with respect to land use we determine farm and field sizes, as been dependent on prices, natural conditions, and structural variables, such as farm technologies. Then we pursue the idea that a geometrical interpretation of land use can help us to define an interface between farming, landscape modelling, and ecological concerns. This interface goes along economic rationales for income of farmers and ecological rationales for a redesign of landscapes. Next, for integrating ecological oriented nature components into a landscape planning, as been based on economic incentives, a payment scheme has to be introduced. Such payment scheme becomes part of farmers’ objective functions in a non-linear model. Core decision variables are the longitudinal stretch of field sizes and the transversal stretch of farm sizes. Then, given various natural frames within an overarching subdivision of field parcels, farms and the landscape are optimised. The suggested approach can be sequentially solved taking into consideration natural conditions and behaviour. Furthermore, a central focus is on policy instruments: 1. We cater for impacts of price policies on landscape structure (farm size) and ecology (heterogeneity of fields). Note, in this context, that it is important to depict the growth of fields as being a consequence of imposed price pressure, modern technology application, and income aspirations. 2. The ecological impacts of this process, also from intensity of farming, are addressed and measured as a diversity index. 3. Policies can be selected that maintain farm income and correct for negative ecological effects of field size changes. For this reason we suggest a principal agent approach and offer objective functions.

The paper explores the question of diversity in agricultural practice as related to bio-diversity and landscape appearance. It starts with the observation that, in the past, diverse natural conditions have considerably impacted on adapted modes of agricultural production, more than today, and that previously performed farm practices were strongly affiliated with specific natural conditions. These practices positively contributed to a modified, diverse and man-made environment which is frequently considered a beautiful landscape. This has changed dramatically. Particularly, where the European countryside is regarded a natural heritage, today, the public seems to be worried about modern farm practices. After the adoption of modern techniques, farmers prefer to apply unified production technologies and tend to set-up uniform farm structures and product mixes as well as land cultivation practices based on purchased inputs. Farm operations equalise natural conditions and contribute to uniform land rents. However, a rising public concern for the preservation of bio-diversity is asking for change and new measures. Additional to regulations on farm practices governments seek to compensate farmers for nature preservation and production of bio-diversity. Presuming that high biodiversity is dependent on diversity in agricultural practice and landscape appearance due to preserved natural conditions, the paper develops a model that links payments to diversity in farm practice and natural conditions. The applied model is landscape-oriented and classifies farm behaviour according to agronomic conditions. A reference system for a unified technology is presented and implications for payments are discussed using a behavioural approach. This behavioural approach focuses on regional dynamics in natural condition as major determinants for bio-diversity and payments as determinants for farm practices. Payments are directed to re-establish diversity in farm practices, counteract current technology dominance, and assure a new exposure to nature, though only partly. Diversity becomes prevalent; notably according to an economic calculus of costs and benefits from taxpayers' point of view.

This paper will discuss the difficulties to implement the requirement of the application of the EU-wide concept of “gender mainstreaming” in respect to the “Rural Development Programme for Austria” (RDP). Experiences and results from the study “Fundamental principles of ‘Gender-sensitive Regional Development’” commissioned by the Federal Chancellery, Department of Regional Policy, and from the Evaluation on the cross-cutting theme “Equal Opportunities between women and men“ of the RDP are the basis for this paper. They show that most stakeholders in the various administrative and spatial levels dealing with RDP do have difficulties in understanding and implementing “gender mainstreaming” in their field of activity.

Understanding the demand profile of rural tourism is a necessary condition for the successful diversification of any rural economy. Although descriptive analyses have been conducted on this issue, a more generalized framework is required that allows us to explore economic analyses. This paper evaluates the leisure behavior of households that have a preference for rural tourism in Japan. First, we give conceptual consideration to the notion that leisure behavior should be regarded as a form of a home production and explain that households that undertake rural tourism have undergone an upward shift in the home production function to realize a higher utility level. We propose that a preference for rural recreation causes this shift by improving the efficiency of the home production of leisure. Second, as an actual behavior of rural tourism, the characteristics of visitors to pick-your-own farms were statistically tested using data from a nation-wide survey on tourism. Finally, the rural preference function was estimated. The results revealed that the profile of households showing a preference for rural tourism demonstrated both up-market and niche market characteristics, which mirrored findings in European countries emphasizing the importance of a higher academic background, stronger orientation towards outdoor recreation, and greater discrimination with respect to the quality of services and goods received. Preference for rural recreation can be enhanced through the provision of authentic, high quality service and goods and the preservation of the rural environment. Therefore, there will be an increased demand for a farm policy that integrates both agricultural and rural measures.

As modern agricultural growth has been attained through increasing use of material input, it is discussed whether agricultural growth can be sustained in the long run within the limit of environmental tolerance. In order to investigate the possibility of the long-run growth, this study applies aghion and howitt's schumpeterian growth model, and conducts empirical analyses using rice production panel data from eight regions in japan for the period 1984 to 1999. Estimation of the translog cost function, which incorporates quality improvement effects, as well as the growth accounting estimation, reveals that the growth with quality improvement occurs, as the growth with increasing material input is stagnant. The quality-based innovation does not lead to increases in chemical input, implying the shift in innovation plays a key role in attaining sustainable development, which also explains a greater increase in pollution at the early stage of development and its slowing down. Sustainable growth can be attained through quality innovation even if environmental regulations are tightened.

The evaluation of rural development programs in the EU should provide information on the implementation and impacts of EAGGF co-financed programs in accordance with Council Regulation (EC) Nr. 1257/1999, help to re-orient existing programs in terms of their goals and budget allocation in order to improve the administration, implementation and the achievements of their targets. This presents an overview of mi-term evaluation results of measures to improve marketing of agricultural quality products in Austria. They are offered in the rural areas of all federal states and received 2.4 Mio. € of public assistance in the years 2000 to 2002; 179 projects were approved during that period. The effects of the measures undertaken were estimated according to the guidelines of the European Commission, DG AGRI, on the basis of monitoring data collected at the application stage and data from a questionnaire. The results are discussed with a view to isolate indicators which would allow for an unambiguous ranking of programs.

Based on the recently completed project on land tenure and the management of land and trees in Asia and Africa (Otsuka and Place 2000), this article attempts to identify the process by which population pressure leads to the individualization of land rights and its consequences on the management of land and trees. A particular focus will be placed on the development of agroforestry systems growing commercial trees, such as cocoa, coffee, cinnamon, and rubber, which are becoming important farming systems in agriculturally marginal areas, where people are particularly poor and natural forests have been degraded rapidly (Otsuka 2000).

The conceptual framework is discussed in the next section, which is followed by the examination of the results of case studies on the management of trees and cropland. Policy implications of this study are discussed in the final section.

This paper uses data from a survey of two hundred and fifty cattle keeping households in three cattle keeping systems; intensive, semi-intensive and extensive systems to estimate the value of non-market, socio- economic benefits of cattle in Kenya. These benefits of cattle keeping are of special importance in developing countries, where financial markets function poorly and opportunities for risk management through formal insurance generally absent. However, when estimating the total contribution of livestock, these non - market functions are often ignored since they are difficult to value, yet they may contribute to a better understanding of livestock production systems. The use of contingent valuation method is employed in this study to elicit these non-market values. Econometric estimations are then used to assess the factors influencing the non - market benefits function. The results indicate that these benefits are highly valued by cattle keepers and comprise approximately 20% of the animal.s total value across the three systems. They are influenced by various production system and household related factors. Implications for policy are drawn.
