n the Northeast Himalayas (NEH) region, four major conventional land-use types are forest, Jhum lands, fallow lands and plantations, but little is known about their sustainability responses to changes. We collected soil samples at two uniform depths (0-15 15-30 cm) from Zunheboto district of Nagaland (India). The dataset was statistically analyzed by conducting an ANOVA-one way, principal compo...

At any point in time, a cleared parcel of forest land (CPFL) used for swidden agriculture exists in either the fallow or in the non-fallow state. Further, the practice of swidden agriculture requires one to operate in an environment of uncertainty. These two points notwithstanding, there are virtually no probabilistic models of swidden agriculture that explicitly account for the above dichotomy...

Because species, populations and ecological processes occur at a range of spatial scales, it is vital to incorporate a multi-scale approach into an assessment of ecological condition and conservation measures (Poiani et al. 2000). This is consistent with the National Forest Management Act which requires the maintenance of viable and well distributed populations throughout all national forest la...

The natural ecological lands, such as forest land, grassland, wetland, etc., constitute the most important factor for maintaining and preserving earth’s ecosystem, which must be well concerned in regional function-oriented planning sustainability of human economic development. We analyzed evaluated change land regions where we applied major zones introduced a new concept China. Using land-use d...

The determination of transition rules that farmers adopt to manage crop-fallow after forest clearing, is essential for deciding a sustainable strategy for forest conservation. The effect of the type of farms with respect to these transition rules in forest border may mitigate incentive measures planned by forest conservation policy. Agent-base modeling (ABM) of land use is a relevant approach t...

Tropical peat swamp lands in the Southeast Asia which store tremendous large amount of carbon in their peat layer and abundant biodiversity are now endangered by human activities such as deforestation, forest fires, land development and urbanization. To earlier start a better environmental policy for conservation of nature of the tropical peat swamp area is one of the preferential global issues...

Low stature tropical forests, such as found on the Yucatán Peninsula, Mexico, are globally a threatened ecosystem, largely due to human habitation and development of agricultural activities. The virtual abandonment of sisal production surrounding Mérida has facilitated the regeneration of large areas of secondary forest. These forests provide multiple services, including carbon sequestration an...

Shifting cultivation (jhum cultivation), a common practice of converting forest land into agricultural by slash and burn is threatening the ecosystem. This study assesses effect shifting cycles on soil quality in North-eastern Himalayan region using minimum properties. To achieve this goal, index (SQI) approach multivariate techniques were used for surface (0-30 cm) subsurface (30-70 layers soi...
