The bias against mangrove areas in siting fish farms prompted a comparison of the cost structure and yield performance in upland and mangrove locations. Tools utilized included descriptive statistics, budgetary and cash flow analyses and profitability ratios. Empirical results revealed that substantial revenue could be realized from both farms. While the upland farms yielded average gross reven...

The campaign for community forestry in upland areas of northern Thailand reflects an ‘arborealised’ perspective on upland agriculture. Arborealisation – which I define as the process whereby upland livelihoods are recast as forest livelihoods – is evident in the main elements of NGO and academic advocacy for the resource rights of upland peoples. As a result of this arborealised perspective, se...

This study evaluates the watershed-scale effects of non-point-source (NPS) pollution loads caused by rice straw mulching and no-tillage applications in upland crop areas using the Hydrological Simulation Program–Fortran (HSPF) model. The study area is the Byulmi-cheon watershed (1.21 km2) of South Korea. Hourly rainfall, discharge and stream water quality data were collected for three years (20...

How do farmers in poor, remote upper-watershed areas of developing countries respond to price signals? Until relatively recently, it was widely assumed that most upland agriculture was primarily for subsistence. If correct, this has important implications for the design of upland development programs, as subsistence farmers, by definition, are beyond the reach of economic policies, and programs...

Landscape heterogeneity causes spatial variation in disturbance regimes and resilience. We asked whether the resilience of bryophyte (liverwort and moss) assemblages to clear-cutting differs between streamside and upland boreal forests in northern Sweden. We hypothesized that bryophyte survival and recolonization rates are higher in streamside areas, thus raising resilience. Conversely, disturb...

There is lack of adequate information on the fertility situations of the soils of Abakaliki urban flood plains. Farming activities have therefore been carried out on the surrounding uplands only. This study was therefore conducted in 2009 raining seasons, to evaluate the fertility status of the flood plains and compare it with the fertility of the uplands with a view to making recommendations f...

Most studies on similar coexisting species enumerate ecological differences which presumably reduce the demand for common resources and allow coexistence (MacArthur 1958, Root 1967, Stallcup 1968). As Schoener (1974) pointed out, however, these differences alone do not demonstrate the role of competition in structuring avian communities. Even if niches were arranged randomly with respect to one...
