Sustainability assessment of crops' production in India: empirical evidence from ARDL-ECM approach

PurposeThe study aims to evaluate the long- vs short-run relationships between crops' production (output) and crops' significant inputs such as land use, agricultural water use (AWU) and gross irrigated area in India during the period 1981–2018.Design/methodology/approachThe study applied the autoregressive distributed lag (ARDL) bounds testing approach to estimate the co-integration among the variables. The study uses the error correction model (ECM), which integrates the short-run dynamics with the long-run equilibrium.FindingsThe ARDL bounds test of co-integration confirms the strong evidence of the long-run relationship among the variables. Empirical results show the positive and significant relationship of crops' production with land use and gross irrigated area. The statistically significant error correction term (ECT) validates the speed of adjustment of the empirical models in the long-run.Research limitations/implicationsThe study suggests that the decision-makers must understand potential trade-offs between human needs and environmental impacts to ensure food for the growing population in India.Originality/valueFor a clear insight into the impact of climate change on crops' production, the current study incorporates the climate variables such as annual rainfall, maximum temperature and minimum temperature. Further, the study considered agro-chemicals, i.e. fertilizers and pesticides, concerning their negative impacts on increased agricultural production and the environment.

Anthropogenic Transformation of Some Properties and Composition of Gazh Gray-Brown Soils of the Ganja-Gazakh Plain

Gay gray-brown soils are distributed mainly in the foothills of the Lesser Caucasus, on the Ganja-Gazakh plain and in the lower reaches of the Araz basin. They are formed by changing volcanic rocks in hot and dry climates. In the process of erosion and soil formation, pyrite, alunitized and other sulfur-containing rocks turn into gazh, on which gray-brown gazh soils are formed. As a result of human activity, i. e. deep plowing and irrigation, these lands are being converted. It turned out that the transformation of these soils is clearly felt in the thickness of the humus layer, its distribution along the profile, quantity and composition. The thickness of the humus layer increases from 40–45 cm to 100 cm. As a result of the transformation, the length of the humus profile is constantly decreasing. Changes in the composition of humus led to an increase in the content of humic acids. Although the coefficient in the uncultivated area decreased from 1.36 to 0.80, in the irrigated area it changed from 1.70 to 0.93.

A Heritage Agronomic Study as a Database for Monitoring the Soil Salinity of an Irrigated District in NE Spain

This article presents and reviews the soil salinity data provided by a rescued vintage agronomic report on an irrigated area of 35,875 ha located in the center of the Ebro River basin, in the NE of mainland Spain. These data come from a soil sampling campaign conducted from May to the first half of July 1975 for the purpose of delineating saline and non-saline soils. The agronomic report was produced in response to demands from farmers to combat soil salinity, and represents the state of the art in those years for salinity studies. Our paper presents the scrubbed soil salinity data for this year, checking their consistency and locating the study sites. The main finding is the unearthing of this heritage report and the discussion of its soil salinity data. We show that the report supplies an assessment and a baseline for further soil salinity tracking by conducting new measurements either by direct soil sampling or by nondestructive techniques, providing an estimate of soil salinity at different locations. This task is feasible, as shown in our previously published articles involving nearby areas. A comparison of the salt amount in the soil over the years would provide a means to evaluate irrigation methods for sustainable land management. This comparison can be conducted simultaneously with analysis of other agricultural features described in the report for the irrigation district in 1975.

Etude Comparative De La Rentabilité Des Systèmes De Pompage Solaire Et Thermique Sur Le Périmètre Irrigué De Soumarana Au Niger

Le Niger dispose d’important potentiel de terre irrigable et plusieurs formes d’irrigation ont été développées notamment la petite irrigation, afin de réduire la dépendance de la production vis-à-vis des aléas climatiques. L’objectif de ce travail est de justifier le besoin de vulgariser la technologie des équipements de pompage solaire. Pour cela une enquête technicoéconomique a été conduite auprès d’un échantillon de 80 exploitants choisis de manière aléatoire sur le périmètre irrigué de Soumarana, à raison de 40 irrigants utilisant des systèmes de pompage thermique et 40 des systèmes de pompage photovoltaïque. Les cultures de carotte et d’oignon, étant les principales spéculations, ont été retenues pour conduire l’étude afin de comparer les performances de systèmes de pompage en place. Il ressort de l’analyse des résultats que le système de pompage solaire dégage des marges brutes nettement supérieure à celles du système de pompage thermique avec des différences de l’ordre de 402 148 FCFA/ha et 342 812 FCFA/ha respectivement pour la culture de carotte et celle de l’oignon. De même, le coût du pompage du mètre cube d’eau en système de pompage solaire est nettement inférieur à celui du système de pompage thermique avec respectivement 57,27 FCFA/m3 et 80,75 FCFA/m3. Ces résultats indiquent une meilleure performance du système de pompage solaire comparativement au système thermique. Niger Republic has significant potential for irrigable land and several forms of irrigation have been developed, including small-scale irrigation, in order to reduce the dependence of production on climatic hazards. The objective of this study is to justify the need to popularize solar pumping equipment technology. To this purpose, a techno-economic survey was conducted among a sample of 80 farmers chosen randomly in the Soumarana irrigated area, at the rate of 40 farmers under fuel powered pumping system and 40 under photovoltaic pumping system. Carrot and onion crops, being the main speculations, were selected to conduct the study to compare both pumping systems performances. The analysis of the results shows that the solar pumping system has higher gross margins than the fuel powered pumping system with differences of the order of 402 148 FCFA/ha and 342 812 FCFA/ha respectively for carrot and onion crops. Similarly, the cost of pumping per cubic meter in the solar pumping system was clearly lower than that of the fuel powered pumping system with respectively 57.27 FCFA/m3 and 80.75 FCFA/m3. These results indicate a better performance of the solar pumping system compared to the fuel powered ones

OVERVIEW OF IRRIGATED AGRICULTURE EVOLUTION IN SOUTHEASTERN BRAZIL BETWEEN 2006 AND 2017 2 ABSTRACT This research aimed to contribute to the debate about the current situation of irrigation in Brazil, with emphasis on the Southeast region. Based on data from the IBGE Agricultural Censuses of 2006 and 2017, we aimed to understand which directions irrigated agriculture has taken in Southeastern Brazil during this period. There was an increase in the irrigated area in Brazil in all geographical regions, reaching 6.9 million hectares (Mha) in 2017. In the period 2006-17, the expansion of the irrigated area in the state of Minas Gerais was 616,000 hectares, in São Paulo it was 321,000 hectares and 155,000 hectares in Espírito Santo. In the Southeast region, drip irrigation is the majority in the area, with 25% of the area irrigated, followed by sprinkler irrigation (24%) and central pivot (23%). The irrigated area in the Southeast region, according to the 2017 Census, is mostly for temporary crops (48%), permanent crops (29%), horticulture and floriculture (14%), and livestock (10%). These information are important for planning the sustainable expansion of irrigated agriculture and efficient water use. Keywords: irrigated area, census of agriculture, irrigation methods.
