Forest cover transitions in the developing tropics are conditioned by agricultural change. The expansion, intensification, and diversification of agricultural land uses are tied to regional economic/environmental regimes and decisions of local farming households. Land changescienceandagrariansystems research sharean interest in the drivers of household strategies, land use impacts, and typologi...

Significant increases in rice production can be obtained in sub-Saharan Africa (SSA) by increasing rice grain yield in existing production systems, expanding rice harvested area, and reducing harvest and postharvest losses. However, availability of labour at critical times is often a major constraint, and this situation is aggravated by the effects of the HIV/AIDS pandemic. Delays during harves...

There has been increasing interest in managing forest stands as uneven-aged structures to promote sustainable harvests as well as maintain ecosystem services. This study provides a framework for simulating conversion of mature even-aged stands to uneven-aged slash pine (Pinus elliottii Engelm.) stands using the USDA Forest Vegetation Simulator (FVS) model. A total of 73 scenarios, representing ...

This paper investigates the consequences of imperfect and uneven factor market development for farm efficiency in rural China during transition. In particular, we estimate the extent to which an inverse relationship in farm productivity can be attributed to the administrative (instead of market) allocation of land, and the extent of unevenly developed non-agricultural opportunities. Using a rec...

The history of land struggles in the United States demonstrates how ongoing patterns uneven development depend upon and codify legacies white supremacy. In this article, we show histories supremacy continue to be embedded institutionalized into contemporary property politics through processes racialized using case Sapelo Island, Georgia. We trace relations on over four periods (covering 1802–20...

Choropleth maps are the most widely used map type for mapping rates, such as those involving disease, crime, and socioeconomic indicators. The essential step of choosing a geographic unit to map is often made in an ad hoc manner. Among the desirable characteristics of choropleth mapping units are high degree of resolution, homogeneity of population size, homogeneity of land area, observation of...

This paper investigates the consequences of imperfect and uneven factor market development for farm efficiency in rural China. In particular, we estimate the extent to which an inverse relationship in farm productivity can be attributed to the administrative (instead of market) allocation of land, and the extent of unevenly developed non-agricultural opportunities. Using a recently collected ho...

The growth of human populations and their resource needs have stressed the conservation of natural land resources. Many policies and programs have been implemented to address the pressures on land resources and notwithstanding this pressure, significant acquisition of land for conservation has occurred throughout history in the U.S., and internationally. Here we assess the on-the-ground result ...
