On farm conservation of crop diversity entails policy challenges, especially when the diversity of crops maintained on farms has both inter-specific (among crops) and infra-specific (within a crop) components. Survey data is used to compare the determinants of inter- and infra-specific diversity on household farms in the highlands of northern Ethiopia. Physical features of the farm, and household characteristics such as livestock assets and the proportion of adults that are men, have large and significant effects on both the diversity among and within cereal crops grown, varying among crops. Demographic aspects such as age of household head and adult education levels affect only infra-specific diversity of cereals. Though there are no apparent trade-offs between policies that would enhance one type of diversity (richness) versus another (evenness), those designed to encourage infra-specific diversity in one cereal crop might have the opposite effect on another crop. Trade-offs between development and diversity in this resource-poor system are not evident. Market-related variables and population density have ambiguous effects. Education positively influences cereal crop diversity. Growing modern varieties of maize or wheat does not detract from the richness or evenness of these cereals on household farms.

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.

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.

As regards EU accession of Hungary one of the most important questions is how the adaptation of the Common Agricultural Policy (CAP) will affect the competitiveness of the Hungarian agriculture. Competitive effects of CAP can be revealed in several ways (quantitative, comparative analysis, simulations etc.) but the results may differ significantly. That is why it is interesting to compare the results of different methods.

This paper concentrates on the competitive effects of changing trade policy by comparing the results of comparative analyses (producer prices, export subsidy systems and import protection) and simulations. The results of the simulation confirm the conclusion that the CAP adaptation will favour basically the cereal production. CAP adaptation will intensify the already existing (competitive) differences between the two large sectors of agriculture (plant and animal products). All of the analyses came to the conclusion that the prospects of arable crops are favourable. Less reassuring are the prospects of animal products. There are apparent efficiency problems, and rising feed costs (due to accession) may further weaken the position of this sector. Without basic structural reforms the sustainability of the sector’s competitiveness is questionable.

The paper attempts to quantify determinants influencing dynamics of employment decisions on agricultural households in Slovenia and to test specific aspects of labour reallocation during transition period by application of agricultural household model. Through the use of 1991 . 2000 panel data for 22,055 farm households, quantitative analysis of intertemporal employment decisions of farm holders is carried out by the use of probit techniques. Determinants tested refer to personal characteristics of reference persons (gender, age, education level, opportunity off-farm income), household characteristics (size, structure), characteristics of the agricultural holding (economic size, labour input, labour intensity) and local labour market conditions. The model results generally confirm the existing empirical evidence on asymmetrical and irreversible participation of holders at the labour market. Despite intensive restructuring of agriculture and profound changes in non-farm labour market in the analysed period, labour supply of farm holders remains rigid. Mobility of labour supply is lower than expected, which can be attributed to the importance of structural problems constraining intersectoral mobility. A marked tendency towards upkeeping of the same employment status is more distincted in the case of holders employed on the farm. A low level of labour supply mobility worsens efficiency of labour allocation on agricultural holdings in Slovenia. Elements of this problem emerge on both, supply (e.g. low level of educational and professional attainment of reference persons) and demand side of labour market (e.g. unfavourable local labour market conditions).

Identifying ways to increase market participation by smallholder producers requires identifying variables that influence market access. This is usually achieved using probit estimation. An important phenomenon affecting entry decision-making is the entry decision of a "similar" household, where similarity is measured in terms of "location". When neighborhood influences are significant, it is important to allow for them in discrete decision contexts, such as probit estimation. This paper, therefore, assesses the magnitude of neighborhood influences in smallholder decisions concerning market entry. The empirical model is based on a cross-section of (110) farms situated in northern Philippines, visited (twice) in the 2000-2001 production year (a panel of 220 observations). The vehicle for analysis is a Bayesian formulation of a standard probit model, but one that allows for spatial autoregression in the decision vector. Estimation requires a Metropolis- step addition to a basic Gibbs sampling algorithm and generates useful insights concerning quantities that are important for market-access policy.

Projections of world food demands hinge critically on the underlying functional form used to predict future demands. Simple functional forms can lead to unrealistic projections by failing to capture changes in income elasticities of demand as consumer becomes wealthier. This paper compares several demand systems in the projection of disaggregated food demand across a wide range of countries with different income levels using a global general equilibrium model. We find that the recently introduced AIDADS system represents a substantial improvement over existing demand systems currently in use in CGE modeling. In particular, our projection results show that for relatively poor regions experiencing rapid income growth, the widely used LES and CDE demand systems tend to over-predict growth in consumer demand, and hence import and output requirements for food products and under-predict that for non-food products, compared to the AIDADS system. On the other hand, for high-income regions with modest income growth, the choice of functional form is less critical.
