Opis:
The aim of the present study has been an attempt at the assessment of agricultural drought vulnerability. The paper presents the proposal of the methodology and the preliminary results. The assessment is performed for the voivodships and the regions in Poland and takes into account two factors: the crop water deficit in the growing season and the share of light and very light soil area in the overall arable soil area. The vulnerability is evaluated for five crops with the largest area of cultivation in Poland. A differentiation of vulnerability to drought between crops and a spatial differentiation for each crop are determined. A spatial differentiation is similar for all crops. The most vulnerable region is the central and central-western part of Poland. The results indicate that late potato is the most vulnerable crop to be damaged by drought among all studied crops, whereas winter rape is the least vulnerable crop.

Opis:
The paper includes a detailed water need forecasting analysis of fruit plants: apple trees, pear trees, cherry trees and plum trees, for the area of Poland with particular water deficits. The assessment was carried out for the multiannual period of 1989-2018, using three methods developed by Press, Grabarczyk and Rzekanowski, and Treder. The greatest water needs in the multiannual period (1989-2018) were demonstrated by apple and plum trees. The average water needs of apple trees in the multiannual period were 485 mm (Press method), 599 mm (Rzekanowski and Grabarczyk) and 558 mm (Treder), respectively. The average amount of water needs of plum trees was 506 mm (according to Press), 590 mm (Rzekanowski and Grabarczyk) and 548 mm (Treder). In practice, each of the methods presented should be used to forecast the water needs of fruit plants. This will minimise the risk of water shortages and will also enable determination of irrigation doses.

Opis:
Drought is characterised as a recurring climatic phenomenon with prolonged duration, affecting land through below-average rainfall and often accompanied by high temperatures. When the available water falls below the optimum level, water deficit or water stress arises, disrupting normal plant processes. This condition poses challenges for plant growth and development as it hampers the internal water transport, induces stomatal closure, and limits access to photosynthetic resources. The study employed the annual sunflower as the experimental plant. The plants were cultivated in a controlled environment with a temperature ranging from 20 to 25°C and a humidity level of 55 to 60%, supplemented by MARS HYDRO artificial LED lighting set to a 12-h photoperiod. Radial changes in the plant stems were monitored using a DD-S type dendrometric sensor to measure radial fluctuations. The collected data were recorded in a dendrometric data logger DL 18. Data collection occurred at hourly intervals from February 20 to March 9, 2023. The nine plants were divided into three groups, each comprising three plants. All plants from groups 1 and 2 received irrigation at one-day intervals (group 1 - 80 cm3 per plant, group 2 - 40 cm3 per plant) and group 3 was not irrigated. Based on these findings, visible water stress was evident in the plants under experimental conditions. Consequently, continuous monitoring throughout the growing season will be essential to adjust the irrigation rate to meet the requirements of the plants.

Opis:
Competitive interactions are common in plant communities, but the underlying mechanisms and effects of competition have not been fully elucidated to date. A pot experiment (3 series in 2009- 2011) was conducted to evaluate the effect of a sowing method of spring barley and Italian ryegrass, and different water condition on the nitrogen (N) content and accumulation in the aerial biomass of plants at different stages. The experimental factors were as follows: 1) sowing regime – pure sowing and mixed sowing – spring barley undersown with Italian ryegrass, 2) water supply – plants supplied with water to meet their full requirements and 50% water supply reduction. The N content of the aerial biomass of plants was determined at five phenological development stages of spring barley grown in a pure stand under optimal soil moisture conditions: leaf development, tillering, stem elongation, heading and ripening. Nitrogen uptake was determined based on the N content and dry matter accumulation in plants. Nitrogen concentrations in the aerial biomass of barley and ryegrass varied throughout the growing season. Nitrogen content was particularly high in leaves, and it decreased steadily during plant development. Neither the sowing regime nor the water supply exerted significant effects on the N content of the aerial biomass of spring barley. In Italian ryegrass, under optimal water supply, mixed sowing with spring barley decreased N concentrations in shoots only during tillering. In spring barley, mixed sowing reduced N uptake by biomass, and the observed decrease was exacerbated under water deficit. In Italian ryegrass, reduced water supply decreased N uptake, but the effect of competitive interactions between the analyzed species was usually stronger than the influence of water deficit. Differences in N accumulation in aerial biomass were determined by the amount of biomass produced in mixed stands and the responses of barley and ryegrass to water deficit.

В статье проводится оценка дефицитов воды для трехкосных лугов в некоторых районах северной части Польши. Оценка основывается на декадных водных балансах почвы. Дефициты воды исчисляли после исчерпания легко доступной растениям воды. В северо-западной части Польши луга на почвах с хорошим влагозадержанием должны орошаться с июля по сентябрь, а на почвах со слабым влагозадержанием - уже с мая. В северо-восточной части страны луга на почвах с значительной влагоемкостью не нуждаются в орошении, а на почвах с небольшой влагоемкостью должны орошаться с июля.
Water deficiency of three-cut meadows in some northern regions of Poland is estimated on the basis of the ten-day water balance of soil. The water deficiency was calculated after exhaustion of readily available water in soil. In north-western part of Poland the meadows on soil with good water retention should be irrigated in the period July-September, whereas on soil with small water reserve - as early as since May. In the north-western part of Poland the meadows on soil with high water capacity do not require any irrigation, whereas those on soil with low water capacity should be irrigated since July.

Opis:
Drought, water scarcity and climate changes are very important threats for agriculture on a global basis. Remote Sensing (RS) is accepted as a technique to collect data and determine water stress indices. Water Stress Indices (WSI) are useful tools to prevent drought and determine irrigation scheduling. The water stress indices are primarily identified as the Crop Water Stress Index (CWSI) and the Water Deficit Index (WDI). The effect of soil background is major problem to establish CWSI especially during early growth stage measurements of canopy temperature (Ts). Hence, WDI is a better index when it comprised with CWSI because of Ts. CWSI and WDI can be determined by two different techniques. These are determined by using measured by using traditional components to collect data and estimated methods by applying RS components to collect necessary data. Estimated method has many advantages when this method compared with measured method. However, estimated method needs some RS components which are infrared gun (IR), sling psychrometer, Spectro radiometer. With the help of these tools, the necessary data are obtained and WDI is determined. By using Spectro radiometer vegetation indices are defined. Among the many vegetation indices, the Normalized Difference Vegetation Index (NDVI) is mostly used one. By using NDVI determination of vegetation cover is easy and accurate technique to establish WDI. Establishing these both stress indices with less fieldwork and by saving money, time and labor conveys the necessary information for agriculturists using remotely sensed data especially for large agricultural fields.

The aim of the article is to explain the key definitions connected with water security and to analyse state relations in the context of water issues. In this context therefore water can be seen to be a precious resource because there it has no substitute. Thus the lack of water security is emerging as one of the major barriers for economic and social growth in developing countries and a source of domestic conflicts. On the other hand, water-related events might result in international cooperation, as Kofi Annan noticed during the celebration of World Water Day: “Fierce national competition over water resources has prompted fears that water issues contain the seeds of violent conflict. [...] If all world’s peoples work together, a secure and sustainable water future can be ours”. What is certain, in the near future any environmental security planning will have to take into consideration the prime issue of water security.

Opis:
The aim of the present work was to investigate the acclimation potential of acacia hybrid (Acacia mangium Willd×Acacia auriculiformis A.Cunn.ex Benth)vegetative propagules to soil water stress in the nursery of Institute of Forestry and Environmental Sciences, Chittagong University. Acacia hybrid showed significant decrease in total plant biomass in two months water-stressed conditions. Allocation of assimilates to root growth relative to shoot found to be an important acclimation mechanism. Leaf area ratio (LAR)increased under water-stressed plants with simultaneous increase in specific leaf area (SLA)but almost no change in leaf weight ratio (LWR). Significant increase in LAR with limited water supply by increasing SLA was likely to be an important acclimation potential since this relative increase in leaf area compensated, at least partially, for a lower photosynthesis under water-stressed conditions aswas evident from decreased mean total biomass under water-stressed regimes.

Opis:
In the present research, a scripting cartographic technique for the environmental mapping of Ethiopia using climate and topographic datasets is developed. The strength of the Generic Mapping Tools (GMT) is employed for the effective visualisation of the seven maps using high-resolution data: GEBCO, TerraClimate, WorldClim, CRUTS 4.0 in 2018 by considering the solutions of map design. The role of topographic characteristics for climate variables (evapotranspiration, downward surface shortwave radiation, vapour pressure, vapour pressure deficit and climatic water deficit) is explained. Topographic variability of Ethiopia is illustrated for geographically dispersed and contrasting environmental setting in its various regions: Afar, Danakil Depression, Ethiopian Highlands, Great Rift Valley, lowlands and Ogaden Desert. The relationships between the environmental and topographic variables are investigated with aid of literature review and the outcomes are discussed. The maps are demonstrated graphically to highlight variables enabling to find correlations between the geographic phenomena, their distribution and intensity. The presented maps honor the environmental and topographic data sets within the resolution of the data. Integration of these results in the interpretation maps presented here brings new insights into both the variations of selected climate variables, and the topography of Ethiopia.

Opis:
Powierzchnia naszej planety w ponad 70% pokryta jest wodą, przez co stwarza się wrażenie o powszechnej obfitości wody na Ziemi. Jednakże dla oceny zależności naszego bytu od zasobów wodnych jest istotna dostępna ilość świeżej (słodkiej) wody. 97,5% wszystkich zasobów wód na Ziemi stanowią wody słone oceanów, mórz, części jezior i wód podziemnych. Zasoby wody świeżej stanowią więc zaledwie 2,5% światowych zasobów i w prawie 70% występują one w zlodowaceniach Antarktydy, Grenlandii, obszaru Bieguna Północnego i w wyższych partiach gór. Stąd też ilość świeżej wody, dostępna dla ludności do bezpośredniego spożycia stanowi mniej niż 1% światowych zasobów (0,7%) [1, 8, 10, 13, 19, 33, 76].
The commonly held belief that there is widespread abundance of water on Earth, is grossly exaggerated. It comes from the fact that 70% of our planet is covered with water. However, the amount of accessible fresh water to satisfy our living needs constitutes less than 1% of world resources. Moreover, only this amount of water is regularly renewed by the ecosystem in the form of rainfall and snowfall. Water resources vary depending on the region: Middle East and South Affrica - 1000 m3 per person per year, Poland - 1460, Europe - 4560, World-7400, Central America - 23 900. Regions particularly deficient in water resources are the Middle East, South Africa, Poland and a number of regions in Europe. This inequality in accessibility of fresh water resources leads to a lot of cross-border tension and conflicts. According to the UNESCO report this situation may lead to many wars over water in the near future and may pose a threat to world peace. The Framework of the UE Water Directives from 2000 obligates membership countries to ensure that by 2010 they have implemented balanced policies concerning water consumption. The arrangements of the EU Water Directives were implemented in Poland in 2001 under The Water Law Act. During the 20th century the world population increased almost three times, whereas water consumption increased sevenfold. According to the statistics of the UN from 2001 the world population will increase from 6.8 billion at present to 9.8 billion by 2050. At the same time, according to the most optimistic prognosis the population in Poland will decrease from 38.5 to 36.6 million accordingly, and by the most pessimistic prognosis to 29.6 million. Simultaneously, a very unfavorable change in the structure of Poland's population will take place as a result of the process of ageing. The WHO and UNICEF estimates from 2004 state that 1.1 billion of the world population did not have any access to fresh water. At the same time 2.6 billion did not have proper sanitary conditions. It resulted in 5 million deaths per annum. Daily water consumption per capita in the most developed countries was equal to monthly water consumption per capita in the economically underdeveloped countries. It has been commonly agreed that water should be considered as a universally accessible natural resource. The poorest who cannot afford to pay for water consumption should be subsidized. The population of our planet will have a chance of surviving, providing people learn how to live without wasting water resources and how to manage them rationally and economically. Water safety should be given the same recognition and priority as electrical safety.

Opis:
On Earth water is an irreplaceable asset, and an estimate of its resource capacity is necessary. The improper selection of indicators of water resources can lead to the underestimation or overestimation of the actual resources present. Incorrect assessments of water resources contribute to the improper completion of necessary water management tasks, thereby failing to satisfy the needs of different water users such as industry, agriculture and forestry, inland water navigation, tourism and recreation and the general population for the purposes of municipal water use. This article discusses the advantages of utilizing Earth Observation technology for estimating water resources in Poland. Despite the large amount of water on Earth, decades of wrongly pursued water management have led to a critical point in maintaining this valuable resource. According to actual estimations, there are enough fresh water resources in the world; the problem is the uneven distribution and pollution of these resources, especially in the case of surface water. Currently, Poland, in comparison with other European countries, is classified as a country with very little water resources. It is important, however, that a thorough evaluation using the latest measurement technologies is conducted, particularly for groundwater resources in deep layers of the lithosphere. The proper assessment of water resources requires knowledge of the hydrogeological conditions within each of the catchments of the analyzed area. International data sets are mostly incomplete and heterogeneous, which makes the comparison of data of several years difficult and often leads to mistakes. While analyzing Polish water resources several factors should be taken into account, including: the amount of rainfall, the amount of water in rivers, lakes and groundwater, and the above-mentioned factors affecting the measurement of the amount of disposable water resources. This article is an introduction to the broader analysis of water resources in Poland and an exploration of the issue from a different perspective.

The results of research into leaf stomatal variability of five European beech provenances originating from Austria, Bosnia and Hercegovina, Germany, Romania and Serbia are presented in this paper. Aim of the study was to investigate how stomatal traits of provenances originating from different environments change in response to drought stress and to assess the phenotypic plasticity of the stomatal features investigated. The study was conducted during two different years, characterized by contrasting weather conditions (2010 and 2011). Two-way ANOVA revealed that provenances differ significantly in terms of stomatal density (SD), width of stomatal aperture (Wb), potential conductance index (PCI) and relative stomatal pore surface (RSPS), during both seasons. In a dry year (2011) all provenances significantly increased stomatal density by between 16.1% (Hasbruch – DE) and 21.9% (Cer – SRB). Guard cell length (LA) was not statistically different among provenances in either year (2010 and 2011), even though LA decreased in the dry year (2011) in all provenances. Reaction norms were steep in most of the parameters suggesting the possibility of a plastic response of provenances toward changes in soil water regime, influenced by the prevailing weather each year. Phenotypic plasticity indices were the highest in regards of SD, PCI and RSPS, indicating that these traits would be good candidates for improvement in breeding programs aimed at selection of drought resistant.

W pracy przedstawiono ocenę niedoborów wodnych, o różnym prawdopodobieństwie przewyższenia, kapusty głowiastej białej uprawianej na Wyżynie Małopolskiej. Obliczenia przeprowadzono metodą bilansowania zapasu wody użytecznej w warstwie korzeniowej gleby z użyciem modelu CROPBALANCE. W pracy wykorzystano dane meteorologiczne Instytutu Meteorologii i Gospodarki Wodnej z lat 1971–2010 – dobowe sumy opadów z 6 stacji (Borusowa, Igołomia, Książ Wielki, Miechów, Olewin oraz Sielec) oraz średnie dekadowe wartości temperatury powietrza, ciśnienia pary wodnej, prędkości wiatru i usłonecznienia ze stacji meteorologicznej Kraków-Balice. Niedobory wodne oszacowano dla uprawy kapusty na pięciu typach gleb, o zróżnicowanych zdolnościach retencyjnych, występujących na Wyżynie Małopolskiej. Niedobory o prawdopodobieństwie przewyższenia 20% wynosiły w okresie wegetacji od 14 (na czarnoziemach) do 115 mm (na rędzinach). Na glebach Wyżyny Małopolskiej o średnich zdolnościach retencjonowania wody (110– 160 mm) niedobory wodne kapusty wystąpiły nawet w latach przeciętnych pod względem ilości opadów (o prawdopodobieństwie 50%). Badania potwierdziły dużą zmienność warunków glebowych i pluwialnych w tym regionie oraz wykazały celowość stosowania modelu CROPBALANCE do oceny niedoborów wodnych upraw warzywniczych.
The paper presents an assessment of crop water deficit of white cabbage with a different exceedance probability, grown in the Małopolska Upland. The calculations were made by balancing readily available soil water in the root zone using the CROPBALANCE model. The study was based on the meteorological data of the Institute of Meteorology and Water Management from the period of 1971– 2010 – daily precipitation from 6 stations (Borusowa, Igołomia, Miechów Książ Wielki, Olewin and Sielec). The average 10-day air temperature, water vapour pressure, wind speed and the sunshine hours data were collected from Kraków–Balice weather station. Crop water deficits were estimated for cabbage growing on five soil types with a different soil water retention capacities, which occur in the Małopolska Upland. Water deficits (at 20% exceedance probability) of cabbage grown on the Małopolska Upland soils varied during the growing seasons from 14 mm (black soils) to 115 mm (rendzina soils). Deficits on the soils with medium retention capacity (ZWU = 111–158 mm) were even in the years in terms of the average amount of rainfall (with probability 50%). The highest water deficits of cabbage occur on lighter soils (e.g. rendzina) and are much greater than on brown soils of loess. The study confirmed the high variability of the soil and pluvial conditions in the region and demonstrated the usability of applying the CROPBALANCE model to assess crop water deficits of vegetable crops.

Opis:
The aim of the study was to evaluate the resistance of caraway genotypes to water deficit based on the estimation of cell membrane stability (CMS) in leaves using polyethylene glycol (PEG) test. In 2007 and 2008, 25 selected caraway genotypes, originating from European botanical gardens (18), cultivars (2) and our own breeding strains (5), were tested. The plant material was collected from the experimental field. The obtained results showed highly significant differences in cell membrane injuries (p = 0.001) among investigated genotypes. The rank of genotypes in membrane injury index in 2007 was similar to that of 2008. Caraway genotypes originating from Warsaw (49.4%), Cracow (45.3%), Reykiavik (39.9%), Berlin (23.8%), Wisley (22.7%) and strains 9/2 (23.7%), 60/8 (22.2%) exhibited a high level of injury, which showed weak CMS and their high sensitivity to drought. The lowest extent of membrane injury was observed in genotypes originating from Bayreuth (4.2%), Ulm (4.4%), Cluj (5.5%), Lousanne (6.8%) and cultivar "Kończewicki" VI/4 (6.2%), which proves low sensitivity of these genotypes to water deficit and cell membrane stability. These genotypes may be used in further breeding program to improve caraway resistance to drought.
