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 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: 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.

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:
In rural Punjab of Pakistan, women from small farm families have a huge role to play in realizing the potential that the country has in livestock sector to flourish. The study presents the current socio-economic condition of women livestock raisers, the extent and nature of their participation in livestock management activities, the impact of women's participation on their families' welfare, and the factors affecting their participation in livestock management activities. The type and size of the family, respondent's age, distant location of the village from the city, and the overall developmental status of the district had their impact on different aspects of rural women's status. At each of the three geographical levels, women respondent's participation level in livestock management activities was multiple of that of their husbands' level. Cultural norms, gendered division of labor, availability of family labor, and the physical condition of the participant were found more operative in determining the nature and level of participation of the family labor in livestock management activities. Participation of the family labor, various aspects of women's status, livestock related factors, and economic factors were the main causes identified as the factors affecting women's participation in livestock management activities. Improving women's role in livestock management and production is essential in improving overall family's health, education, income, and food security. The results signify the need for geographical targeting and the importance of using a gendered approach in the agricultural development programs.

Abstract:
L'objectif est d'évaluer sur le plan agro-climatique les options de réalisation d'une culture de printemps dans les hautes vallées du Nord du Vietnam. A partir d'hypothèses sur les contraintes agro-climatiques s'exerçant sur ces options, un modèle de simulation et le dispositif expérimental permettant de le caler et de l'évaluer ont été élaborés. Une expérimentation virtuelle replaçant les cultures de printemps envisagées (riz, riz « aérobie », maïs et soja) dans le climat de trois régions contrastées sur ce plan a ensuite été réalisée, le long d'un gradient d'altitude, et sous différentes modalités techniques, notamment de dates de semis. Cette démarche a été appliquée successivement aux deux grands cas de figure rencontrés dans les montagnes : irrigation des parcelles dès le printemps, et conduite en régime pluvial (irrigation praticable seulement pour le cycle estival). Elle a conduit à identifier, pour chacun de ces cas de figure et chacune des régions et cultures étudiées des fenêtres de semis favorables, intervalles de dates de semis pour lesquelles la culture de printemps présente peu de risques. La taille de cette fenêtre constitue ainsi un indicateur synthétique de la contrainte climatique pour une culture donnée dans un lieu donné : plus cette fenêtre est étroite, plus on peut s'attendre à ce qu'il soit délicat pour les producteurs de pratiquer la culture. Les résultats confirment clairement que même lorsque l'eau d'irrigation est abondante, le climat des montagnes du Vietnam ne permet pas partout de pratiquer une culture de printemps. Les risques identifiés sont la destruction par le froid pendant les stades précoces de la croissance végétative, l'allongement du cycle au-delà de la date où le riz irrigué d'été doit être installé selon la pratique actuelle, l'obtention de rendements nettement abaissés du fait de la faiblesse du rayonnement global et des températures pendant la première partie de la saison. Pour ce contexte irrigué, la culture qui échappe le mieux à ces contraintes dans les simulations est le soja, suivie du maïs et du riz conduit en semis en plein champ. Le riz semé en pépinière et repiqué est apparu comme le plus sensible aux contraintes de températures.En conditions pluviales, la culture de printemps est nettement plus délicate tout particulièrement à cause des retards de levée et des stress hydriques pendant la phase de croissance végétative liés aux faibles précipitations de début de saison. Le soja reste la culture pour laquelle la contrainte de durée de cycle est la plus faible, mais son rendement simulé est fortement réduit par les stress hydriques. Le riz « aérobie » et le maïs sont des options envisageables en conditions strictement pluviales aux altitudes relativement modestes dans tous les climats étudiés. La géographie de l'extension des cultures de printemps au Vietnam est ainsi esquissée. Des perspectives de recherche sont proposées en vue d'accroître cette aire d'extension. Outre ces acquis importants pour l'agriculture locale, cette thèse confirme l'intérêt et l'efficacité d'une approche de modélisation ad hoc pour ce type de question agro-climatique
The goal of this thesis was to assess the agro-climatic feasibility of introducing a supplementary crop during the spring season in the high valleys of the mountainous northern Vietnam. From hypotheses drawn about the way climate constrained such crops, a simulation model and the experimental device required for calibrating and evaluating it were elaborated. A virtual experiment was carried out in order to submit the candidate crops (rice, “aerobic rice”, maize and soybean) under the contrasted climates of three regions, along the elevation gradient and under several technical management, especially sowing dates. This approach was applied consecutively to the two major cases occurring in these mountains: crop irrigated during the whole spring, and rainfed crop (land irrigable during summer only). This approach led to identify, for each of these two cases and for each of the studied regions and crops, favourable sowing windows, i.e. intervals of sowing dates for which the risks associated to spring crop are low. The size of such windows provides a synthetic indicator of the climatic constraint for a given crop at a given place: the narrower the window, the more difficult it is expected to be for farmers to practice the option.Results clearly confirmed that even if irrigation water is abundant, the climate of the mountains in Vietnam does not allow practicing the spring crop everywhere. The risks that were identified were crop destruction by lethally cold temperature during early vegetative stages, maturity delayed beyond the date at which the irrigated rice of summer must have been sown according to current practice, and obtaining yield neatly decreased due to low global radiation and temperature during the first half of the season. Under irrigated conditions, the simulated crop that best escaped these constraints was soybean, followed by maize and direct seeded rice. Rice sown in nurseries and transplanted showed more sensitive to temperature constraints.Spring crop showed strongly trickier under rainfed conditions, especially due to delays in seedlings emergence and water stresses during vegetative growth, in relation with low rainfall during the early part of the season. Soybean remained the crop with the shortest duration, but its simulated yield was strongly reduced by water stresses. “Aerobic rice” and maize were possible options under fully rainfed regime at relatively low elevations only, under any of the regional climates studied. Thus, the feasibility area of spring crops was thus sketched. Research perspectives were proposed, aiming at increasing this area. Additionally to these results, targeted at serving local agriculture, this work confirmed the value and effectiveness of an ad hoc modelling approach for agro-climatic studies of this kind

Abstract:
This study focuses on modelling the changes in rainfall patterns in different agro-climatic zones due to climate change through statistical downscaling of large-scale climate variables using machine learning approaches. Potential of three machine learning algorithms, multilayer artificial neural network (MLANN), radial basis function neural network (RBFNN), and least square support vector machine (LS-SVM) have been investigated. The large-scale climate variable are obtained from National Centre for Environmental Prediction (NCEP) reanalysis product and used as predictors for model development. Proposed machine learning models are applied to generate projected time series of rainfall for the period 2021-2050 using the Hadley Centre coupled model (HadCM3) B2 emission scenario data as predictors. An increasing trend in anticipated rainfall is observed during 2021-2050 in all the ACZs of Chhattisgarh State. Among the machine learning models, RBFNN found as more feasible technique for modeling of monthly rainfall in this region.

Abstract:
In Ethiopia, 85% of the population is engaged in agriculture (CSA, 1999). Agriculture supplies a significant proportion of the raw materials for the agro-industries, and accounts for 52% of the gross product and 90% of the export earnings. A wide range of climatic, ecological, and socioeconomic diversities influence Ethiopian agriculture. The dependency of most of the population on rain-fed agriculture has made the country’s economy extremely vulnerable to the effects of weather and climate, which are highly variable both temporally and spatially. If rains fail in one season, the farmer is unable to satisfy his needs and pay his obligations (tax, credit, etc). Farmers remain in the bottom line of poverty and lead a risky life. Moreover, due to climatic change and other human-induced factors, areas affected by drought and desertification are expanding in Ethiopia (NMSA, 1996a; WMO, 1986). There are three major food supply systems in Ethiopia (IGADD, 1988; Teshome, 1996): crop, livestock, and market-dependent systems. Cropbased systems are practiced principally over the highlands of the country and comprise a very diverse range of production, depending on altitude, rainfall, soil type, and topography. Any surplus above the farmer’s need is largely dependent on, for example, good weather conditions, absence of pests and diseases, availability of adequate human and animal power. Failure of rains during any cropping season means shortage of food supply that affects farmers and others. The livestock system constitutes about 10% of the total population, which is largely based in arid and semiarid zones of the country. This system is well adapted to highly variable climatic conditions and mainly depends on animals for milk and meat and is usually supplemented by grains during nondrought years. Approximately 15% of the Ethiopian population is market dependent and is affected by the preceding two food supply systems. Its food supply (grain, pulses, and oil seeds) has been facing serious shortages due to recurring droughts. People’s purchasing power determines access to food in the market-dependent food supply system. In Ethiopia, an agricultural drought is assessed using the concept of the length of growing period (LGP).

Abstract:
Land expansion to increase agricultural production in East Africa (Burundi, Ethiopia, Kenya, Rwanda, Tanzania and Uganda) will be limited by climate change. In this study, we predict landscape suitability for chickpea (Cicer arietinum), common bean (Phaseolus vulgaris), lentil (Lens culinaris), field pea (Pisum sativum) and pigeon pea (Cajanus cajan) cultivated across diverse agro-ecological zones (AEZs) in East Africa from 1970 to 2070, under the 4.5 emission scenario. Our aim was to understand how suitability shifts among the AEZs might affect the agricultural potential of the selected crops. We use the geolocations of each crop together with response curves from the species distribution software, Maxent to fine-tune the expert based EcoCrop model to the prevailing climatic conditions in the study region. Our optimal precipitation and temperature ranges compared reasonably with the FAO base parameters, deviating by ±200mm and ±5oC, respectively. There is currently a high potential for lentil, pea and common bean in the region. However, under future climates, the suitability of common bean and lentil with a much narrow climate range will shrink considerably while pigeon pea and chickpea will continue to be suitable. Under projected climatic conditions, the agricultural potential of these legumes will be limited by drought or heat stress as landscape suitability will shift optimally toward the cool sub-humid (tcsh), and the cool semi-arid (tcsa) zones. Tanzania, Kenya and Uganda will be the most affected and will lose a large share of suitable arable land. Different adaptation measures will be needed to increase the agricultural potential and optimized production in vulnerable AEZs. In general, smallholder farmers will have to substitute lentil and common bean for chickpea and pigeon pea or other suitable substitutes to address food security issues. Notwithstanding the limitations of this study, our results highlight the vulnerability of legumes crops as well as their production zones which could be useful in the formulation of adaptation strategies for the East African region.

Abstract:
Soybean has an ecological adaptability due to the deep selectivity of this crop in relation to the specific features of the growing zone. At the same time, it makes increased demands on heat and moisture, especially during certain "critical" periods of growth and development. The lower threshold of active average daily temperatures is 15–17oC, and for full maturation of ultra-ripe and early-maturing varieties, the sum of active temperatures of 1700–2100oС is required. Assessment of the agro-climatic resources of the Ryazan region indicates the possibility of growing precocious soybean varieties here. The limiting indicator in some critical periods may be insufficient moisture. As a result of the conducted research, it was found that soybean varieties of the Northern ecotype are able to form a stable yield in the conditions of the Ryazan region. At the same time, the lesser response to changes in agroclimatic conditions was shown by the Kasatka variety, which showed the shortest growing season and yield at the level of 1.00 t / ha. The Georgiya variety reacted more than any other to changes in weather conditions, its yield was from 1.24 to 1.72 t/ha over the years of research.
