Deforestation for conventional farming has affected soil quality (SQ) worldwide. The goal of our study was to evaluate the impact land use change, from forest subsistence farming, on SQ in Benin. Composite soils forest, horticultural, agricultural, fallow, and degraded lands were collected analyze chemical physical properties. Using inductive additive approach principal component analysis (PCA)...

Production and area of chickpea are reducing every year in India due tocompetition with horticulture and other cash crops in irrigated areas. There is a greatscope for expanding chickpea production with or without limited irrigation in rainfedrice fallow lands (RRFL) in the states of Chhattisgarh and Madhya Pradesh. Nineteenchickpea genotypes were tested using participatory varietal selection (...

   Agricultural hillslopes with susceptible loess enters a large amount of runoff and sediment into the Gorgan city annually, due to the inappropriate drainage system which cause a lot of financial losses city. The purpose of this study was to investigate the effect of different vegetation scenarios on the runoff and sediment discharge from three hillslopes of catchment of ​​5.9 hectares. The r...

Abstract Background Soil quality, which can be inferred using indicators that interact synergistically, is affected by land use types and agricultural management practices. This study assessed the status of soil quality under three adjacent uses (cultivated, grazing, fallow) in Kersa subwatershed (622 ha). samples were collected from surface (0–20 cm depth) identified with replications paramete...

In the Congo Basin, smallholder farmers practice slash-and-burn shifting cultivation. Yet, deliberate burning might no longer be sustainable under reduced fallow scenarios. We synthesized data from the Forest Margins Benchmark Area (FMBA), comprising 1.54 million hectares (ha), in southern Cameroon and assessed the impact of fire exclusion on yield, labor inputs, soil fertility, ecosystem carbo...

extended abstractintroductionin recent years, several studies around the world have shown that land use has a strong impact on water quality, and significant correlations exist between water quality parameters and land use types. generally land use types have adverse impacts on water quality, so positive relationships exist between percentages of these land use types and concentrations of water ...

This study explores the influence of land-use and land cover (LULC) changes on temperature over North India (NI) North-Eastern (NEI) during 1981–2006 by subtracting reanalysis from observed (observation minus (OMR) method). The normalized difference vegetation index (NDVI) data AVHRR satellite for period were analyzed to understand type LULC this their linkage with change two regions. results O...
