A set of pre-formulated hypotheses about the potentials of inland valleys to agricultural production in general, and livestock (dairy) - based enterprises in particular, were tested with data collected from five regions comprising 71 villages/towns and 630 households in three countries (Nigeria, Mali and Côte d'Ivoire). The study was undertaken to test hypothesis concerning the potentials of the inland valleys systems to agricultural production, and those pertaining to the intensification of livestock production in the valleys systems and their relationships with demand for livestock (dairy) products. Results from the analysis showed that many of the previously held views about inland valley and their potential were supported by the data from the three countries. Most of the hypotheses relating directly with inland valley potentials were accepted in the majority of locations. However, there were few hypotheses which were not supported by data from all countries and study sites. The overall assessment from the surveys is that the potentials of the inland valleys towards dairy production are currently good in all the countries and could be better if the resources available in the inland valley environments (for example crop residues) are better managed and utilized. Intensive use of inland valleys was related more to population density than access to market. Similarly consumption levels of domestic dairy products were influenced by population concentration. Instead access to market influenced positively farmers' practices towards specialization and intensification of dairy production. Increase demand for milk and dairy products is met by intensification and not by increase in herd size. Efforts to ensure continued milking through feeding was not related to herd size. As revenues (sales and home consumption) increased, more lands were left to fallow. These results confirm the assertion that the presence of inland valley systems for cropping and livestock rearing promotes diversification of agriculture, and presumably reduces farmers' production risks.

The paper aims at analyzing agricultural production for energy generation purposes, including the production of agricultural biogas, as an opportunity for functional diversification of agriculture and for multifunctional rural development in Poland. There have been many changes observed in Polish agriculture. New directions of crop production and of the use of agricultural products have emerged. One of the changes is the increasing significance of the production of agricultural biogas and energy from biogas. There have been built both small-scale and large-scale biogas plants. Most of the agricultural biogas plants are located in northern, western and south-western Poland, i.e. in the areas where there are relatively large farms which can provide a supply of substrates necessary for the production of agricultural biogas. The formation of biogas plants and the use of agricultural production for generating energy are an eagerly anticipated trend contributing to the dissemination of renewable energy sources, the functional diversification of agriculture, the development of additional economic activities in rural areas, and the increase in the energy security of particular regions and the entire country.

With this issue of 2008, we bring 49 proceedings of the 85, which started life as presentations at the Annual 14th International Scientific Conference on Research for Rural Development 2008 held at the Latvia University of Agriculture, in Jelgava, on 21st to 23rd May 2008. In the retrospect of four month later, we can count the Conference as a great success. The theme - Research for Rural Development - attracted participation of 357 researches with very different backgrounds. There were 2 presentations from Czech Republic, 1 from Denmark, 1 from Poland, 1 from Sweden, 2 from Estonia, 13 from Lithuania and 65 from Latvia. Four independent reviewers estimated each report. The proceedings of the Conference is intended for academics, students and professionals researching in the area of crop production, animal breeding, agricultural engineering, agrarian and regional economics, food sciences, veterinary medicine, forestry, wood processing and water management.

Since 1990 significant structural changes have taken place in Latvia. First of all, it was the reestablishment of an independent state in 1991 and secondly - the accession to the European Union (EU) in 2004. Joining the EU provided free flow of goods, finances and individuals, a single system of legal acts as well as a trustful image of the state for foreign investors. In Latvia, 60% of the EU funds are allocated for agriculture and rural development, thus achieving the objective of producing food adequate for consumers’ purchasing power and ensuring agricultural commodities are available for their processing. Financial aid for primary industries also results in support for the whole society and other industries from which necessary resources and commodities are purchased. After joining the EU, the growth of the agricultural industry was observed owing to support payments. As a result of the EU policy, the size distribution of farms changed in Latvia, the output and exports of food increased as well as agricultural productivity rose. The research aim is to analyse the changes in and gains for Latvia’s agriculture after the accession to the EU. The following research methods were employed: the monographic and descriptive methods, analysis and synthesis and the logical and constructive methods.
