We show empirically using panel data at the plot and farm level and based on a model incorporating supervision costs, risk, credit-market imperfections and scale-economies associated with mechanization that small-scale farming is inefficient in India.
1. Patch dynamics is a new, potentially unifying mechanism for the explanation of tree-grass coexistence in savannas. In this scale-explicit paradigm, savannas consist of patches in which a cyclical succession between woody and grassy dominance proceeds spatially asynchronously.
Widely occurred woody encroachment in grass-dominated ecosystems has the potential to influence soil organic carbon (SOC) and total nitrogen (TN) pools at local, regional, and global scales. Evaluation of this potential requires assessment of both pool sizes and their spatial patterns.
Prior studies exploring the quantitative relationship between landscape structure metrics and the ecological condition of receiving waters have used a variety of sampling units (e.g., a watershed, or a buffer around a sampling station) at a variety of spatial scales to generate landscape metrics
Moderate-grained data may not always represent landscape structure in adequate detail which could cause misleading results.
This study examines rural women access to and control of agricultural production resources in arable small-scale sustainable agricultural production in a developing country setting.
The relationships between water yields of tributaries and coverage of different vegetation types in the corresponding sub-watersheds were investigated during the wet season in the Heishui River Valley, located in the upper portion of the Yangtze River in western China.
