Problem of water scarcity in agriculture – case study of land improvement in Kujawsko-Pomorskie Voivodship

Rudnicki Roman, Wiśniewski Łukasz

Journal of Water and Land Development

2021

no. 51

17--24

Today’s agriculture is facing a range of challenges, the most important of which is the adjustment to the changing climate. In this context, water management is particularly vital. Droughts in Poland are becoming more and more frequent. That fact adds to the significance of irrigation and drainage systems. This paper is an attempt at diagnosing the condition of (in 2016) and changes in (over the period of 2006–2016) irrigation and drainage systems in the Kujawsko-Pomorskie Voivodship (analysed by communes, until 2016 – according to Local Administrative Units – LAU level 2). The multidirectional analysis involves a comprehensive description of ameliorated lands, including the allocation of the EU funds dedicated for the support of flood protection and land improvement ventures. It has been demonstrated that the present condition of land improvement does not reflect the needs of the agriculture in the studied area and that the changes implemented on the ongoing basis fail to make the situation better. In 2016, slightly over 40% of agricultural acreage was ameliorated, while the level at which land improvement needs would be satisfied approximated 70%. In over 1/5 of the ameliorated area, facilities needed reconstruction or modernisation. Drainage systems were in the majority, which indicates that the current needs, i.e. water scarcity, are not addressed.

Natural fertilization in the structure of fertilization in sustainable agriculture - on the example of Poland

The aim of this paper was to describe the state (as of 2010), structure by type (natural and mineral fertilisation, taking into account doses of nitrogen, potassium and phosphorus) and spatial diversification of fertilisation in the Polish agriculture (16 voivodships and 314 poviats). The studies of these issues concentrated on examining the impact of the external features of agriculture – natural and man-made ones. What has been demonstrated is the presence of a strong spatial diversification of fertilising procedures, mostly due to the impact of man-made conditions: historical and urban. It has transpired that the territorial patterns of fertilisation are bi-polar in nature: on the one hand, there are areas dominated by natural fertilisation (mostly north-eastern Poland); on the other hand, there are places where mineral fertilisation is prevalent (mostly northern and western Poland). Taking into consideration the planned Agricultural Census (2020) as well as the importance of pro-enviormental actions within The Common Agriculture Policy, the used metod of the comprehensive analysis of the feritilization for 2010 year constitutes a good starting point to the evaluation of the occurent changes.

Celem pracy było rozpoznanie stanu (2010 r.), struktury rodzajowej (nawożenie naturalne i mineralne, z wydzieleniem dawek azotu, potasu i fosforu) i zróżnicowania przestrzennego nawożenia w polskim rolnictwie (16 województw i 314 jednostek powiatowych). Podjęto problem kształtowania się wymienionych cech pod wpływem zewnętrznych uwarunkowań rolnictwa – przyrodniczych i pozaprzyrodniczych. Przeprowadzone badania udowodniły silne zróżnicowanie przestrzenne nawożenia, określone przede wszystkim przez oddziaływanie czynnika historycznego i urbanizacyjnego. Wykazano, że układy terytorialne nawożenia mają charakter dwubiegunowy – od obszarów o przewadze nawożenia naturalnego (głównie Polska północno-wschodnia) do dominacji nawożenia mineralnego (głównie Polska północna i zachodnia). Biorąc pod uwagę planowany Powszechny Spis Rolny (2020) oraz rosnącą wagę działań prośrodowiskowych w ramach Wspólnej Polityki Rolnej, wypracowana metoda kompleksowej analizy nawożenia przeprowadzona dla roku 2010, stanowi dobry punkt wyjścia do oceny zachodzących przemian.
