Abstract:

A study was conducted to quantify agro-climatic and agro-ecological zones in north-west India using 34 years (1980-1914) weather data of twenty two agro-meteorological stations of Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Punjab, Haryana, Chandigarh, Delhi, Uttar Pradesh and Rajasthan. The weather data and the coordinates were converted into decimal system for each meteorological station, for spatial analysis. The map of north-west India was digitized and thermal, humidity, rainfall and moisture index and Length of growing period layers were prepared in the GIS environment using Arc GIS 10.1. These layers were combined by union operation and polygons were grouped into different zones. The moisture index and length of growing period zones were integrated with other spatial input layers of soil texture on logical manner to demarcate different agro-climatic and agro-ecological zones and sub zones. Based on texture the soils of study area were broadly characterized in five classes. North-west India was divided into ten agro-climatic zones as Z-1 to Z-10 and thirty six sub agro-ecological zones which represent homogeneity with respect to climate, growing periods and soil texture, which covers all features of abiotic crop environment. These zones helped to adjust cropping season according to moisture, temperature, vegetations and their combination regime. A shift in climatic belt was observed towards south-west as moist sub humid zone in Haryana which did not exist in old climatic map of Haryana. Itwas a new zone noticed in this state. The south-western limit of dry sub humid zone shifted about 40 km and of semi-arid zone shifted to about 60 km. The study will be very useful in the planning of farming system as well as cropping systems and may fill the gaps in ecological zonation of the area.

Abstract:

This study estimates the impact of major climate variables (temperature and rainfall) on crops’ productivity across four agro-ecological zones of Pakistan. The crops selected were rice, wheat, maize, cotton and sugarcane. The study used panel data from 1991 to 2010 and applied panel least square techniques. The results revealed that the effect of climatic variables on crops yield varied across agro climatic zone due to differences in their climate conditions. Temperature and rainfall were the important determinants affecting crops productivity across agro climatic zones of Pakistan. Wheat productivity has been impacted more in Northern Irrigated Plain-a by average temperature and in Northern Dry Mountains by rainfall than the other zones. Rice productivity has been impacted more in Dry Mountains by average temperature and in the Indus Delta by rainfall than other zones. Sugarcane productivity has been impacted more by average temperature and rainfall in Indus Delta than zone IV. Maize productivity has been impacted more by average temperature and rainfall in Northern Dry Mountains than other zones. Finally the study recommends proper mitigative and adaptative strategies to enhance the positive and lessen the adverse impact of climate change on crops productivity across agro climatic zones of Pakistan.

Abstract:

This study sought to analyze the degree of spatial association of soil texture with agro-climatic zones and slope classes on the farmlands of the Jema watershed, in the Northwestern Highlands of Ethiopia. The agro-climatic zones (elevation zones) determine the micro-climate and biota of the study area. Thirty six soil composite samples for texture (the proportion of clay, silt and sand) analysis from four agro-climatic (elevation) zones and seven slope classes were collected. One-Way-ANOVA was employed to compute the mean variability of texture among the identified terrain classes, and linear regression was used to analyze the degree of association between texture and the terrain attributes. The measured values of sand, silt and clay in the watershed ranged from 11.4 to 43.4, 6.0 to 34.8, and 21.8 to 77.8, respectively. The One-Way-ANOVA indicated a significant (p < 0.05) soil texture variation in both slope and agro-climatic zone classes. Heavy clay, clay and clay loam were identified as the major texture classes in the lower, middle and upper parts of the watershed, respectively. The regression analysis showed that texture was more influenced by the difference in the elevation values than in slope values in the watershed. The standardized beta coefficients of slope and elevation for clay particles were 0.499 and 0.767, respectively. For sand, the regression coefficients for slope and agro-climatic zone were 0.485 and 0.812, respectively. This implies that an interactive effect of micro-climate and biota governed by elevation influenced the spatial distribution of soil texture more than slope.

Abstract:

Abstract The objective of this paper was to compare between agro-climatic zones developed from 10-year interval of weather data from 2005-2014, 20-year interval of weather data from 1995-2014 and the zoning developed by [NORELDIN et al. 2016] using 30-year interval from 1985-2014 in the old cultivated land of Egypt in the Nile Delta and Valley. Monthly means of weather data were calculated for each year, and then monthly values for 10-year and 20-years were calculated for each governorate. Basic Irrigation scheduling model (BISm) was used to calculate reference evapotranspiration (ETo). Analysis of variance was used and the means was separated and ranked using least significant difference test (LSD0.05). Our results showed that agro-climatic zoning using 20-year values of ETo was similar to the zones developed with 30-year values of ETo, with different values of average ETo in each zone. Furthermore, using 10-year values of ETo resulted in higher values of ETo in each zone, compared to 20-year and 30-year ETo values. However, the average value of ETo over the three classifications was close to each other. Thus, depending on the availability of weather data, either zoning can be sufficient to develop agro-climatic zones.

Abstract:

Abstract: Momordica charantia L. and Cucumis sativus L. are excellent fruit vegetables in nature having iron content, as an essential constituent required for good health of humans. The iron content of the vegetables may vary from place to place depending on the soil, rainfall and other climatic conditions prevailing in that place. It was thought necessary to find out whether the environmental conditions in the nine agro-climatic zones of Maharashtra have any impact on the iron content of these fruit vegetables. The fruit vegetables were collected from various places from nine agro-climatic zones of Maharashtra classified based on rainfall, soil type and the vegetation. It was found that fruits of Momordica charantia L. showed comparatively more nutraceutical content than the fruits of Cucumis sativus L. collected in same season. It was also observed that in the nine agro-climatic zones of Maharashtra studied, the fruits of Momordica charantia L collected from Karjat of North Konkan Coastal Zone showed maximum Iron content, while fruits collected from Igatpuri of Western Ghat Zone and Nashik of Western Maharashtra Plain (Transaction 2) zone showed minimum iron content. In case of Cucumis sativus L., fruits collected from Wardha of Central Vidarbha (Moderate rainfall) zone region showed maximum iron content, while fruits collected from Surgana of Sub-montane (Transition 1) Zone showed minimum iron content. Keywords: Nutraceuticals, Momordica charantia L., Cucumis sativus L. Environmental factors, Iron content, Agroclimatic zones of Maharashtra.

Abstract:

<p>Afghanistan grows wheat on about 2.5 million hectares with an average annual production of about five million tonnes. The local research and development efforts make use of country wide research results to recommend varieties and other technologies. Afghanistan has wide ranging climatic variability and its wheat acreage therefore needs to be delineated into wheat climatic zones. A set of 10 different types of wheat varieties were scored for average number of days to 50% flowering (ADF) at 10 locations to delineate Afghan wheat acreage into homogeneous wheat climatic zones based on ADF values. The results obtained hinted at creating eastern, northern, south western and a highland zone for conducting research and recommending wheat technologies.</p>

Abstract:

This manuscript aims to create large-scale calculations of agro-climatic factors from global climatic data with high granularity-climatic ERA5-Land dataset from the Copernicus Climate Change Service in particular. First, we analyze existing approaches used for agro-climatic factor calculation and formulate a frame for our calculations. Then we describe the design of our methods for calculation and visualization of certain agro-climatic factors. We then run two case studies. Firstly, the case study of Kojčice validates the uncertainty of input data by in-situ sensors. Then, the case study of the Pilsen region presents certain agro-climatic factors calculated for a representative point of the area and visualizes their time-variability in graphs. Maps represent a spatial distribution of the chosen factors for the Pilsen region. The calculated agro-climatic factors are frost dates, frost-free periods, growing degree units, heat stress units, number of growing days, number of optimal growing days, dates of fall nitrogen application, precipitation, evapotranspiration, and runoff sums together as water balance and solar radiation. The algorithms are usable anywhere in the world, especially in temperate and subtropical zones.

Abstract:

In the North Western Himalayas, particularly Jammu region, where 85% of people depend on agriculture and allied sectors, 70% of agriculture is rain-fed. Various factors, especially land use pattern and variations in climatic conditions affect the soil fertility and nutrient contents. However, information on essential nutrients in the soil across the region is meager. An attempt has been made to study the soil nutrient status under different agro-climatic zones of Jammu region. Seven hundred seventy surface soil samples (0-15 cm) from sub-tropical, intermediate and temperate zones of Jammu region were collected and analyzed for soil texture, pH, electrical conductivity (EC), organic carbon (OC), CaCO3, CEC, available macro nutrients (N, P, K, S) and micronutrients (Fe, Cu, Zn, Mn). The results indicated large variation within the soils of each zone. The amount of all the available nutrients was more in the soils of temperate zone than those of other zones. The soils of sub-tropical zones were low in available N, P, S and Zn and to some extent in K. Organic matter content, clay and silt content of the soil vis-à-vis cation exchange capacity were found to be the main factors controlling the available nutrient content of the studied soils.

Abstract:

AbstractThe objective of this paper was to develop agro-climatic zones in the old cultivated lands of Egypt in the Nile Delta and Valley using climate normals from 1985–2014 to facilitate better irrigation water management under water scarcity conditions. 30-year monthly climate data were collected for 17 agricultural governorates in Egypt and yearly averages and 30-year averages were calculated. BISm model was used to calculate yearly averages of potential evapotranspiration (PET) and 30-year average for each governorate. Analysis of variance was done using one factor randomize complete block design, with number of years as replicates. Furthermore, the mean, the range and R2 were calculated to test the strength of the relationship between PET and climate elements. The means of PET for each governorate was separated and ranked in ascending order using least significant difference test (LSD0.05). The results identified 7 agro-climatic zones (LSD0.05 = 0.146). These zones were: (1) Alexandria; (2) Demiatte, Kafr El-Sheikh and Dakhlia; (3) El-Behira, and El-Gharbia; (4) El-Minofia, El-Sharkia, El-Kalubia, Giza and El-Fayom; (5) Beni Sweif, El-Minia, Assuit and Sohag; (6) Qena; and (7) Aswan. Such zoning will increase the ability of the Egyptian policy makers to prepare the appropriate water management and development policies as a result of the availability of proper information on each zone aiming at efficient use of the limited water resources.

Abstract:

Pea leafminer, Chromatomyia horticola (Goureau) is an important pest of many vegetable and ornamental crops. The present investigation was carried out to study the parasitoid diversity of this pest in different agroclimatic conditions of Himachal Pradesh, India. Sixteen species of parasitoids viz. Diglyphus horticola Khan, Diglyphus isaea (Walker), Zagrammosoma sp., Pnigalio sp., Quadrastichus plaquoi Reina and LaSalle, Asecodes erxias (Walker), Closterocerus sp., Neochrysocharis formosa (Westwood), Chrysocharis sp, Chrysocharis indicus Khan, Pediobius indicus Khan (Eulophidae), Opius exiguus (Wesmael), Dacnusa sp. (Braconidae), Cyrtogaster sp., Sphegigaster sp. (Pteromalidae), and Gronotoma sp. (Figitidae) were recorded parasitizing C. horticola in different agro-climatic zones of Himachal Pradesh. Agro-climatic zone II (sub-temperate mid-hills) was the richest in parasitoid diversity (14 species) followed by zone I (11 species), zone III (7 species) and zone IV (4 species) which are characterized by sub-tropical sub-montane, wet temperate high hills and dry temperate high hills, respectively. Shannon diversity index, species richness, species evenness and species dominance varied from 0.69-1.71, 1.39-2.64, 0.50-0.71 and 0.29-0.50, respectively. D. isaea and D. horticola were the dominant parasitoids of C. horticola contributing 41.46-80.15 and 9.16-50.65 per cent of the total parasitization, respectively, in different agro climatic zones. The study highlights the role of different parasitoids in natural control of the leaf miner and will be useful for designing the IPM strategies for the pest.

Abstract:

AbstractA survey for ectoparasites and gastrointestinal helminths was conducted in 150 chickens raised in a traditional backyard production system. The chickens were randomly selected from six sites in three agro-climatic zones in central Ethiopia, namely Bekoji and Chancho (highland), Woliso and Teji (midland), and Metehara and Zeway Dugda (lowland). The study indicated that in the three agro-climatic zones 126 (84%), 108 (72%) and 97 (64.67%) of the examined chickens were harbouring ectoparasites, nematodes and cestodes respectively. Out of 10 species of ectoparasites, Menacanthus stramineus (40%) was the most frequent species. Postmortem examinations revealed the presence of four species of nematodes (Ascaridia galli, Heterakis gallinarum, Subulura brumpti and Capillaria caudinflata) and four species of cestodes (Raillietina echinobothrida, R. tetragona, R. cesticillus and Choanotaenia infundibulum). The ectoparasite infestation was found to be sex specific in chicken, being significantly higher (P<0.05) in males. On the other hand, endoparasitic infection showed no such difference (P>0.05). No difference was found among the three agro-climatic zones in the frequency of ectoparasite and nematode infection. However, a significant difference (P<0.05) in the frequency of cestode infection among the three zones was observed.

Abstract:

This study investigated the diversity of fungal metabolites in maize across four agro-ecological zones of Malawi. A total of 90 maize samples (for human consumption), collected from farmsteads, were analysed for 235 fungal metabolites using liquid chromatography-tandem mass spectrometry. A total of 65 metabolites were found in the samples. 75% of samples from the hottest agro-ecological zone contained either aflatoxins, fumonisins, deoxynivalenol, zearalenone; or a combination thereof in levels exceeding European Union (EU) maximum levels, whereas the related fraction was only 17% in the cool temperature zone. Aflatoxins, citrinin, 3-nitropropionic acid, monocerin and equisetin were most prevalent and in higher levels in samples from hot agro-ecological zones, whereas deoxynivalenol, nivalenol, zearalenone and aurofusarin were most prevalent in cool agro-ecologies. On the basis of per-capita maize consumption, estimated daily intakes for all samples from hot ecologies were well above the JECFA's provisional maximum tolerable daily intake (PMTDI) of 2.0 μg/kg body weight (bw)/day for fumonisins, whereas the PMTDI of 1.0 μg/kg bw/day for deoxynivalenol was exceeded in relatively more (90%) samples from the cool highlands than the other zones. These results demonstrate the influence of micro-climatic conditions on mycotoxin prevalence patterns and underscores the need for development of agro-ecological specific mycotoxin dietary exposure management strategies.

Abstract:

The phenotypic composition of the North Caucasian population of wheat leaf rust pathogen (Puccinia triticina Erikks.) in various agro-climatic zones of the region in 2016-2018 is analyzed. 233 single pustule isolates were studied, of which 212 virulence phenotypes were identified. In all the years of research, a high level of population diversity was established (the Shannon index (Sh) was 0.92-0.99). The dominant phenotype in 2016 was the PHRS phenotype, which was identified in the southern foothill, western Azov and eastern steppe agro-climatic zones. In the population of 2016, phenotypes with a high and medium number of virulence genes prevailed. In 2017, the most represented are the phenotypes of DCRL, LBLL (Western Azov zone) and PCQB (Northern zone). Avirulent phenotype BBBB was common for populations of 20162018. In 2016, a phenotype with virulence to Lr9 (TLGS) was first detected. In 2017 and 2018, phenotypes virulent to the Lr24 gene (PKTT, SFGQ, CFPQ, TKTS, MKTT, LKSR) were detected in the populations of the fungus. A high level of population differences in phenotypic composition between the years of research was established (Rogers index (R) was 0.96 -0.99).

Abstract:

This paper makes a different, if not a unique, attempt at a quantitative evaluation of the multifarious linkages between irrigation and rural poverty by taking a system approach and using cross-section data pertaining to 80 agro-climatic sub-zones of India for two time points, i.e. 1984–85 and 1994–95. It develops first an analytical framework to depict the most important pathways and layers of irrigation–poverty linkages as mediated though three key systems: water system, agro-economic system and socio-economic and demographic system. These pathways and linkages are, then, translated into an econometric form in terms of a system of simultaneous equations defined by a set of irrigation-related, agro-economic, socio-economic and demographic variables. By estimating this system of equations in the context of the agro-climatic sub-zones of India for the two time points, this paper empirically evaluates the mechanics and dynamics of irrigation–poverty linkages. Based on an analysis of the empirical results, this paper concludes by identifying some of the analytical, methodological and policy issues crucial for understanding and promoting the overall poverty alleviation impacts of irrigation.

Abstract:

Today there is enough scientific research to prove the impact of climate change on agriculture. However, there is no conclusive conclusion as to what is in store for agriculture, its potential will increase or decrease. Significant consequences of the impact of climate change are likely to manifest themselves at the regional level, and this requires additional research for further adaptation of agriculture in the corresponding territory. The aim of the study is to assess changes in agro-climatic indicators at the regional level. The subject is the Komi Republic, located in the extreme northeast of the European part of the country. The chosen research methodology based on statistical processing of agro-climatic indicators for ten meteorological stations in the region for 1960-2018 and economic indicators of productivity and gross harvest of agricultural crops for 1913-2018 due to the large amount of data. Paired regression analysis used accurately interpret the results. The obtained mathematical models evaluated according to the Pearson coefficient, Student’s t-criterion, determination coefficient, F – Fisher’s criterion, so that the results of the study were reliable. For some regions, the consequences of climate change may turn out to be negative in the form of a decrease in food supply, for others - positive, due to an increase in the duration of the growing season and, accordingly, an increase in the potential productivity of agricultural crops. The relevance of the study is because these positive consequences will be especially characteristic for the northern territories. As a result, it revealed that in four agro-climatic regions of the Komi Republic, there were insignificant climatic changes for agriculture over a sixty-year period. An analysis of the yield of vegetables in open ground showed that it increased from 36 to 314 tons per hectare, and the gross yield of the main agricultural crop - potatoes - decreased almost 3 times, but the main reason is the reduction in acreage, and not climate change. However, the trend line for potato yields in the region as a whole shows an upward trend over a 100-year period. The performed paired regression analysis between the selected agro-climatic indicators and the yield of agricultural crops of the republic revealed an average direct relationship only between the yield of vegetables and the duration of the growing season, and the sum of average daily temperatures. Consequently, it is currently impossible to assert that the ongoing climatic changes have a significant impact on agriculture in the Komi Republic

Abstract:

Maximum temperature, minimum temperature and rainfall data of Bankura (1992-2007) and Canning (1960-2006) were analyzed for assessing climatic trend and agro-climatic characterization of red-lateritic and coastal Zones of West Bengal respectively. These two zones are the most vulnerable regions to climate change in West Bengal, hence selected for the present study. While average values of annual maximum temperature and annual minimum temperature were used for climatic trend analysis, no definite trend was observed. So, maximum temperature of the hottest month and minimum temperature of the coldest month were used for detecting climatic trend. The maximum temperature shows positive trend for both the stations. An increasing trend of annual rainfall was also observed. In case of agro-climatic characterization the agricultural draught, meteorological draught, seasonal rainfall and rainfall probability using Markov-chain model were analyzed for the said two stations. Kharif crops of Bankura encountered two years (2000 & 2005) agricultural draught within 2000 -2007, whereas kharif crops of Canning encountered agricultural draught in 2006 within the said period. Likewise, the deviation of seasonal rainfall and probability of two consecutive wet weeks with different levels (10, 20,30,40,50 and 60 mm) of weekly total rainfall was worked out.

Abstract:

SUMMARYThe performances of two remote sensing drought indices were evaluated at selected agricultural sites in different agro-climatic zones in Iran to detect the severity of drought phenomena related to temporal variation and different climatic conditions. The indices used were the perpendicular drought index (PDI) and the modified perpendicular drought index (MPDI), which are derived from moderate resolution imaging spectroradiometer (MODIS) satellite images (MOD13A3 V005). The correlations between these perpendicular indices and two other remote sensing indices in ten different agro-climatic zones of Iran from February 2000 to December 2005 were analysed. The additional indices evaluated were the enhanced vegetation index (EVI) and the vegetation condition index (VCI) along with five water balance parameters, including climatic water balance (CL), crop water balance (CR), monthly reference crop evapotranspiration (ET0), crop evapotranspiration (ETc) and required irrigation water (I). Winter wheat was selected as the reference crop because it is grown in the majority of climatic conditions in Iran.The results show that in several climatic regions, there is a statistically significant correlation between PDI and MPDI and the water balance parameters, indicating an acceptable performance in detecting crop drought stress conditions. In all zones except at the sites located in northwest and northeast of Iran, VCI and EVI are less correlated with the applied water balance indicators compared to PDI and MPDI. In a temporal analysis, PDI and MPDI showed a greater ability to detect CR conditions than VCI and EVI in the most drought-sensitive winter wheat-growing stages. Since Iran is characterized by arid or semi-arid climatic conditions and winter wheat is a major agricultural crop, a combination of both PDI and MPDI could be used as simple remote sensing-based tool to map drought conditions for crops in Iran and in other developing countries with similar climatic conditions.

Abstract:

SUMMARYA cross-sectional study based on a questionnaire survey was conducted to determine the distribution of lumpy skin disease (LSD) and associated risk factors in three main agro-climatic zones of Ethiopia. A total of 330 questionnaire surveys were collected from 44 peasant associations (PA) distributed in 15 districts. Across agro-climate zones, herd-level LSD prevalence in the midland agro-climate was significantly higher 55·2% [95% confidence interval (CI) 47·5–62·6] than in highland and lowland agro-climate zones. Overall observed LSD prevalence at animal-level was 8·1% (95% CI 7·3–8·9) and observed mortality was 2·12% (95% CI 1·73–2·6). The odds ratio (OR) of LSD occurrence in midland vs. highland and lowland vs. highland zones was 3·86 (95% CI 2·61–5·11) and 4·85 (95% CI 2·59–7·1), respectively. Significantly high risk of LSD occurrence was associated with communal grazing and watering management (OR 4·1, 95% CI 2·02–6·18) and introduction of new cattle (OR 8·5, 95% CI 6·0–11·0). Our findings describe the distribution of LSD in different agro-climates in Ethiopia along with associated risk factors, and can help shed light on the epidemiology of LSD in other African countries suffering from the disease.

Abstract:

Improving the territorial location of the agro-industrial complex on the basis of considering the peculiarities of the labor, natural and climatic potential of municipal districts is an important factor in increasing the sustainability of rural development. In the present article, a study of the social, natural-climatic and economic-geographical prerequisites for the specialization of the agro-industrial complex of the Western macro-district was conducted. The results of the study were the definition of spatial development concept for the agro-industrial complex based on the formation and development of specialized agricultural zones in the Western macro-district of the Krasnoyarsk region. It was proved that in the conditions of a market economy, the need for scientifically based specialization of rural areas, the development of inter-district economic relations, the creation of combined industries that provide deep processing of agricultural raw materials becomes particularly relevant.

Abstract:

The main purpose of the study was to investigate the effects of climatic change on potato yield and yield variability in Agro-Ecological Zones (AEZs) of Iran during 2041–2070 (2050s). The Statistical Downscaling Model (SDSM) was performed in this study to downscale the outputs of the General Circulation Model (GCM) and to obtain local climate projections under climate scenarios for a future period. The Just and Pope Production function was used to investigate the impacts of climatic change on potato yield. The results showed that the effects of future climatic change on potato yield and its variability would vary among the different AEZs. Potato yield would change in the range from −11% to 36% across different AEZs during the 2050s. Yield variability is expected to vary from −29% to 6%. Much more generally, the results indicated that the major potato producing zones would experience a decrease in mean potato yield in the presence of climate change. Our findings would help policymakers and planners in designing appropriate policies to allocate the lands under potato cultivation among different zones. These results also have important implications for adopting ecological zone-specific strategies to mitigate the reduction in potato yield and meet food security.
