  In temperate climates, most fruit trees need cold weather, low temperatures in winter, and a certain amount of heat during the growing season until harvest. One of the most apparent effects of climate change is the elevated temperature in all seasons of the year. In our study, the changes in thermal conditions have been calculated in Hungary's most significant growing region of apples using the Chill Unit for winters and the Growing Degree Days for summers. The meteorological data were obtained from the gridded dataset of the Hungarian Meteorological Service on a 10 km × 10 km grid, so the whole studied area is well-covered over the last 50 years. The results show that the trees are more exposed to early budding than a few decades ago. Furthermore, the accumulated heat amount in summers has increased drastically, which may increase the heat stress and lead to higher yield losses.

  The purpose of this paper is to introduce the environmental conditions of the Berettyóújfalu sub-region, which is geographically located in Hajdú-Bihar County. I specifically target the regions’ relief, soil and hydrogeological conditions, climate, flora and fauna, natural value and present nature conservation activities.
  On the basis of my investigation of these points, I can state that although this sub-region has unfavorable soil conditions, polluted surface and subsurface waters, it is rich in thermal waters, nature reservations and wildlife. It’s disadvantageous characteristics can or should be amended, while the advantageous ones should be utilized by considering the principles of sustainability. At the end of this paper, I will make recommendations in connection with the latter point.

  Balmazujvaros as a settlement near Hortobagy has to cope with both advantages and disadvantages. Its natural and social conditions are mainly given, the agricultural characteristic is dominant, and the number of the employed is the highest in the agricultural firms and processing industry. Developing the third sector, including hosting, tourism, eco-tourism, thermal-tourism, may be an opportunity for the city. The subsidy for rural development relating to the SAPARD-programme may contribute to this, as the city is the member of the Association of Hajdu Towns.
  The agriculture plays an important part in Balmazujvaros in which production and marketing of vegetables and fruits excel. Several farmers realised this opportunity and founded the Marketing Co-operative of Vegetable Producers in Eastern Hungary, that is the Kvaliko. This PO works in a Corporation form and is constantly developing, spreading and expanding its choice making use of the local natural, social and economic conditions and applications for realising its investments. This PO may set an example for the other entrepreneurs and farmers of Balmazujvaros to co-operate and it may be considered as an already realised opportunity.
