However, three factors determine the main differences in practices: the marketing channel used, the farmer's environmental objectives, and the farmer's economic behavior, which is linked to the weight of the crop activity in farm revenue.
The next step in constructing the irrigation-augmented model is to divide each and every crop activity in the GTAP database into two crop industries representing irrigated and rainfed production using the SplitCom program [39].
It is important to investigate sun light interception by plant canopy as it affects different crop activities, most importantly the photosynthesis process and hence biomass production.
This article builds on previous research by hypothesising key pathways by which cash crops may affect food crop activities and empirically measuring these effects using the case of cotton in Gokwe North District in Zimbabwe.
Thong et al. (2011) compared the economic efficiency of the summer-autumn and autumn-winter rice crop activities based on data taken from 479 households across four provinces of the Mekong delta.
In addition, SOC loss was found in long fallow plots, and was correlated to steep and low plant cover plots; evidencing that soil degradation does not occur during cropping activity but due to erosion after land abandonment.
Land use activities resulted from systematic combination of crops and inter-crop activities into crop rotations, different crop management techniques (i.e., mechanisation, irrigation and crop protection) and animal production.
Crofting is a low intensity agricultural system restricted to the Highlands and Islands of northern Scotland typified by small scale mixed livestock production and rotational cropping activities.
The results indicate that conjunctive use options are feasible and can be easily implemented in the area, which would enhance the overall benefits from cropping activities.
The PCA results for the entire landscape show that significant variation amongst households is mainly related to the cultivation time input, on-farm income particularly from cropping activities, livestock husbandry, demographic characteristics, agricultural extension activities, and cultivation labour input.
Introduction of non-native plants, establishment of cattle and sheep grazing, missionization of the native population, changes in burning practices during the Spanish period and enhanced cropping activities during North American settlement worked together to substantially modify the mid-California coastal landscape in about a century's time.
