The delineation of shifting cultivation landscapes using remote sensing in mountainous regions is challenging. On the one hand, there are difficulties related to the distinction of forest and fallow forest classes as occurring in a shifting cultivation landscape in mountainous regions. On the other hand, the dynamic nature of the shifting cultivation system poses problems to the delineation of ...

Agricultural production in the Koutiala region, southern Mali, is based on cash sources (cotton and groundnut), cereal sources (maize, sorghum, millet), and a store of wealth (livestock). In these low-input farming systems, crop production is seriously constrained by soil fertility decline. Research is being conducted in the region to investigate the potential of improved fallows planted to leg...

The conclusions of a recent study by Wright and Wimberly (1) suggesting that corn/ soy cultivation in the Western Corn Belt (WCB) “threatens grasslands” are questionable because of the methods and data used. The study (1) compared National Agricultural Statistics Service (NASS) Cropland Data Layer (CDL) for 2006 with CDL for 2011 (2) and found 530,000 ha of net “grassland conversion” to corn/so...

Including green manure into a rice-based double-cropping system has effects on both crop production and greenhouse gas (GHG) emissions. Yet, few studies have considered the trade-off between productivity, profitability, carbon footprint (CF) in this cropping of China. Thus, impacts different regimes economic benefits, footprint, net ecosystem budget (NEEB) were investigated. The treatments rice...

Slash and burn agriculture, largely dependent on the duration of the fallow period to restore the productivity of the land, is extensively practiced by small landholders in Pará State, Brazil. Due to a mounting demographic pressure, fallow periods have been shortened, and signs of agronomic and ecological failure such as decreasing crop yields and structural and compositional depletion of the s...

Dryland wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor (L.) Moench) are often grown using a wheat–sorghum-fallow (WSF) crop rotation on the semiarid North American Great Plains. Precipitation stored during fallow as soil water is crucial to the success of the WSF rotation. Stubble mulch-tillage (SM) and no-tillage (NT) residue management practices reduce evaporation, but the sp...

In the context of China’s trial fallow policy; the heavy metal pollution of farmland is addressed via field surveys in Hunan Province, where the fallow policy has been implemented, and in Jiangxi Province, where it has not been implemented. We measured and analyzed willingness to accept (WTA) using the contingent valuation method (CVM). The conclusions of this study are as follows: (1) Farmer a...

The objective of this article is to investigate why farmers in Kosovo leave land fallow when the total land of their farms is small and households, almost fully dependent on farming for their livelihoods, are large. In order to elicit some of the barriers to land utilization, the article uses a comprehensive survey carried out during the agricultural year 2005/2006 to explore agricultural house...
