Water management for irrigation requires suitable policy tools able to meet social objectives and private behaviour. The legal framework in the EU is today faced with the new water framework directive (60/2000), that sets up new criteria for water management, regulation and pricing. Among other things, the water framework directive introduces the principle of full cost recovery and the polluter pays principle for water users. For many areas of Italy, this may be a significant shift compared to present payment criteria, based on traditional rights, political prices, partial running cost coverage or others. The aim of this paper is to analyse the problem of water regulation in agriculture as applied to irrigation issues. This is made by setting up and testing a simulation model based on the integration of a mathematical decision making model at farm level and a principal agent model at the level of irrigation boards. The model allows to quantify water demand and the optimal regulation from the point of view of the policy maker. The results show major impacts of water availability and prices on farm income. The adoption of a mix of pricing instruments related at the same time to crop rotation, water consumption and pollution can significantly improve water policy efficacy.

In Rwanda for the past decade, rural households have lived with civil unrest and genocide, changing land laws, large population flows both into and out of the country, and climatic threats with droughts and floods. The illness and untimely death of prime age adults from a number of health problems (increasingly HIV/AIDS) adds to the stress of these households and has lasting effects on the ability of households to survive. In this research, the authors use household and member level survey data to increase understanding about what is happening in households with such shocks and how they may be different from other Rwandan rural households.

This research finds that households affected by adult illness and death strive to maintain their agricultural production, and work to avoid selling assets, yet some households appear to be in a downward spiral, losing assets and income earning potential. They rely heavily on social networks for labor and skills, but clearly these networks will be stretched beyond their means in any continuing epidemics. Female-headed households in particular struggle to find labor with neighbors or work more themselves. If special programs are developed for the affected families, focusing on increasing land and labor productivity fits into their own strategies. Since households with prime age death and disease appear to be similar to other Rwandan households in the poorest two quintiles, such programs would be beneficial to rural households in general, and possibly strengthen social networks through generalized agricultural and income growth.

In Uganda, as in much of sub-Saharan Africa, poverty is concentrated in rural areas. Because agriculture accounts for a large share of incomes for these households, policies and external shocks that affect agriculture, including shifts in world prices, changes in agricultural productivity, and reductions in marketing costs, may have significant effects on rural poverty. In this paper, we use a Computable General Equilibrium (CGE) model of the Ugandan economy, explicitly designed to capture regional variations in agricultural production and household incomes, to examine the implications of these policy changes and shocks.

Simulation results suggest that a doubling of area planted to coffee (the government.s target) would increase rural consumption by less than 2.0 percent, because of an estimated 10 percent decline in the world price of robusta coffee and an 11.3 percent real exchange rate appreciation of the Ugandan shilling. Smaller productivity increases in food crops may have greater potential to raise rural incomes, provided that markets perform well and producer incentives are maintained. A five percent increase in agricultural productivity raises consumption by 1.3 to 2.1 percent among rural households and lowers food prices by 3.4 to 3.8 percent relative to the CPI, thus benefiting households with high food consumption shares. Reducing agricultural marketing margins by 30 percent leads to increases of 2.3 to 4.1 percent in consumption of farm households, with the largest gains in regions where consumption out of own production is lower.

For decades the CAP has been the major influence in shaping EU agriculture and food production. The economic and policy environment in the EU is now very different from that which prevailed in the earlier decades. The future economic, social and geographic diversity of the EU will be further increased by enlargement. Agricultural policies and the related operational frameworks will inevitably change to accommodate this added diversity and the changing societal and consumer values. This paper evaluates how the current shape of EU agriculture has been influenced by the reforms to date. It also attempts to focus on where EU farming may be, or wish to go, over the next decade. The evaluation is restricted to the beef sector as it has been to the forefront in the policy reforms of the last decade and because the adjustments were inevitably complex due to the scale of the oversupply problems, the biological and market intricacies involved.

This evaluation concluded that the current EU beef policy is severely constrained with poor targeting of the income supports, high production costs, based on an administratively complex and expensive control system without any clear benefit to either society or taxpayer for a rather large expenditure. In the past, agricultural policy in the EU was primarily driven by the need for a secure food supply and with the objective of sustaining the economic and social needs of farmers. But, in the well fed and affluent EU society of the 21 st century, agricultural policy will be mainly driven by the economic and social goals which are rapidly changing. This society places a declining value on extra units of food production, but an increasing value on any public goods consumed in the production process. As a consequence, the mix of agricultural production and public goods that this society is prepared to support financially is changing rapidly. The level and components of farm incomes in the EU in the 21 st century will reflect these changes. Farm revenue will likely consist of a mix of payments for conventional agricultural products and public goods. The public good payments will be conditional on the level and type of inputs used, farming practices, types of products produced and a societal vision of the role of farming. This will affect production costs, scale of operation and the future configuration of agriculture and rural society. To meet this evolving situation the paper also develops and outlines a multi-commodity framework by which the EU could reorient its direct payment (DP) system to incorporate a range of public good values to the mutual benefit of consumers, taxpayers and farmers.

This paper examines the factors influencing farmers' participation in several agri-environmental schemes. A multinominal logit model is used to separate between participating and nonparticipating farmers. In addition this model allows to predict farmers participation in one measure as well as in different measures simultaneously. Data stems from a survey conducted in eight European countries and includes a description of both farmer and farm characteristics. Three categories of schemes have been analysed: landscape maintenance, biodiversity protection and restriction of intensive farming practices. The combination of these three types of schemes provides eight possible packages which can be selected by eligible farmers.

The multinominal logit model shows the importance of both farm and farmer as well as attitudinal characteristics on the participation in different combinations of schemes. For instance, the environmental concern favours landscape maintenance and biodiversity protection as well as their combinations with schemes requiring restrictions of intensive practices. However, it has a negative effect on the single participation in schemes requiring restrictions of intensive practices only. Our analysis confirms a number of previous findings. In addition, it shows the importance for policy makers to take into account that farmers have the opportunity to enter several schemes simultaneously. Indeed, due to cost complementarities, joint participation provides both private and public benefits.

In the context of the mid-term evaluation of rural development programmes (EU regulation 1257/99) the Bavarian agri-environmental programme, the so-called Kulturlandschaftsprogramm Part A” (KULAP-A), was evaluated. By means of this programme, only agricultural land related measures are supported. The measures may refer to the whole agricultural enterprise, parts of it or the individual plot. The guideline of the EU-commission demand analysis about the effects of the programme on biotic and abiotic environmental resources such as soil, water, species and their habitat and landscape. This paper focuses on the results concerning the protection of soil erosion and water contamination. For this, statistical data corresponding the supported measures were analysed. Additionally a survey of farmers participating and non-participating at the programme was conducted. In this study the dead-weight-effect is discussed as an effect which can be excluded in cases when: due to the programme an intensification of management is prevented, a low intensive management is reached or the abandonment of farming could at least be delayed.

The collapse of the former Soviet Union has led to a sharp decline in the trading of agricultural products between its successor states. There have been attempts to revive these trade relations by means of bilateral and regional trade agreements. In addition, almost all member states of the CIS are in the process of negotiating accession to the World Trade Organization (WTO). Because of its size and agricultural production potential, the Russian Federation is of primary importance in this respect. The integration of the Russian Federation in the world economy, which is expected to result from its accession to the WTO, will have a sizeable impact not only on its own agricultural sector, but also on the world markets for agricultural products.

This paper evaluates the consequences of considering environmental and economic risk in the analysis of cost-effective nitrogen abatement options in crop production. A farmlevel mathematical programming model incorporating nitrogen leaching variability, field time variability, yield variability, and output price variability is developed.

The empirical results reveal that requiring a high reliability with respect to a desired abatement target can be extremely costly, due to the high variability of nitrogen emissions. It appears to be sufficient to reduce average nitrogen load in order to reduce the environmental risk associated with nitrogen leaching variability, since a change to crops with lower average load also results in lower variability of nitrogen emissions. A farmer’s degree of risk aversion has some effect on the economically optimal choice of crop mix. However, it is more important to consider the utilisation of machinery and labour resources and crop rotation effects, than considering risk aversion.

This paper's aim is an assessment of economic effects of Slovenia’s accession to the EU in the field of agriculture and a discussion about some key dilemmas about the introduction of CAP in the new member states. For the purpose of assessing economic effects, a new sectoral model of Slovenian agriculture APAS-PAM has been compiled which allows assessment of market and income effects for ten key agricultural products with regard to various accession scenarios. The accession under the scenario of equal treatment of new member states would bring significant improvements in the aggregate income levels. On the other hand, discrimination of the candidate countries in the field of direct payments (“phasing in” process) would result in a fall of aggregate income level by an eighth. Moreover, noncompetitive production structures in the food-processing sector would deteriorate the economic situation of agricultural production by up to further 40 %. The positive effects of different accession scenarios are expected in the sugar beet and - under assumption of eligibility for direct payments - also in coarse grains, beef and sheep meat production. The economic situation in milk production is not expected to change significantly. The negative accession effects can be expected in pigmeat, cereal, egg and, potentially, poultry production. The results reveal a great significance of the equal treatment and differentiation approach to negotiation process for the preservation of the economic situation of Slovenian agriculture after accession. This holds especially for cereal, beef and sheep meat production.

One of the most critical stages in the development of any family business is the transfer of its ownership and control to the next generation. However, the process by which this transfer is achieved in farming has been one of the least-researched facets of farm business management. This paper draws on an on-going research project which seeks to remedy this omission. Comparable data for a total of 3,500 farms in England, France and Canada has been analysed to provide a portrait of the main features of the process in which the older generation retires from the farm while the younger generation takes over its ownership and management. The paper begins by defining the three distinct, but interrelated, processes of inheritance, succession and retirement. Focusing on the process of succession, it briefly summarises some of the main similarities and differences in current practice among farm families in the three countries. Having presented a typology of patterns of farming succession based on a review of the literature, the paper goes on to modify this in the light of findings from the more recent surveys.

The adoption of more efficient farming practices and technologies that enhance agricultural productivity and improve environmental sustainability is instrumental for achieving economic growth, food security and poverty alleviation in sub-Saharan Africa. Our research examines the interaction between public investments, community health, and adoption of productivity and land enhancing technologies by households in the northern Ethiopian state of Tigray. Agricultural technology adoption decisions are modeled as a sequential process where the timing of choices can matter. We find that time spent sick and opportunity costs of caring for sick family members are significant factors in adoption. Sickness, through its impact on household income and labor allocation decisions for healthcare and other activities, significantly reduces the likelihood of technology adoption. Our findings suggest that agencies working to improve agricultural productivity and land resource conservation should consider not only the financial status of potential adopters, but also their related health situation.

The public R&D capital stock is introduced as a quasi-fixed input in a variable cost function. The relative shadow price allows the correct measurement of the equilibrium levels of quasi-fixed inputs thus explicitly assessing the hypothesis of public R&D under (over) investment. By introducing an appropriate R&D price in the long-run equilibrium, the model can also provide empirical evidence on the rationale driving public R&D investment and on the hypothesis that free-riding on public R&D can explain overinvestment. Moreover, the model allows a formal testing of the induced innovation hypothesis and a more accurate calculation of both internal rate of return to R&D and residual exogenous productivity growth. The empirical implications of the model are appraised in the case of Italian agriculture for the period 1960-1995.

Using a partial equilibrium model of world agriculture, we investigate the multilateral removal of all border taxes and farm programs and their distortion of world agricultural markets. These distortions have significant terms-of-trade effects. World trade is also significantly impacted by both types of distortions. Trade expansion is substantial for most commodities, especially dairy, meats, and vegetable oils. Net agricultural and food exporters (Brazil, Australia, and Argentina) emerge with expanded exports; whereas net importing countries with limited distortions before liberalization are penalized by higher world markets prices and reduced imports. The US gains significant export shares in livestock products and imports more dairy products. Without protection and domestic subsidies, the EU loses many of its livestock and dairy export markets.
