    This paper explores household variation in land tenure security and drought shocks across villages to investigate the extent to which land tenure systems matter in households’ capacity to cope with adverse impacts of weather shocks for agricultural dependent households in rural Malawi. Our findings reveal that land tenure security cushions the effects of drought regimes on food security. Further, we establish access to credit facilities for farm investment purposes as the underlying channel that mediates the impact of drought shocks on food insecurity.

    The discussion on the relation between human mobility and climate change has moved beyond linear and exceptional terms. Building on these debates, this article, and the Special Issue on Climate Mobilities: Migration, im/mobilities and mobilities regimes in a changing climate that it introduces, conceptualises this relation in terms of climate mobilities.

    Bhutan

    Arable land in Bhutan is under serious threats of land degradation. Proper land management approach is needed to control soil erosion problems. This study is an attempt to characterize and document the conventional and the community-based land management approaches, applied in Chukha and Dagana districts, respectively. The study tried to make a comparative assessment of their social, economic and environmental impacts on the participating farmers.

    There has been a trend to encourage organic agriculture in response to improve global food security. This article investigated how organic agriculture contributed to food security of small land holders experiencing organic agriculture. It involved in-depth interview, focus group, and participatory observation from a purposive sample of thirty participants at San Sai and Muang Wa Villages, Luang Neua Sub-District, Doi Sa Ket District, Chiang Mai Province, the north of Thailand.

    This essay explores the changing landscape of food sovereignty politics in the shadow of the so-called ‘land grab’. While the food sovereignty movement emerged within a global agrarian crisis conjuncture triggered by northern dumping of foodstuffs, institutionalized in WTO trade rules, the twenty-first-century food, energy and financial crises intensify this crisis for the world’s rural poor (inflating prices of staple foods and agri-inputs) deepening the process of dispossession.

    Most early alley cropping studies in semi-arid Kenya were on fairly flat land while there is an increase in cultivated sloping land. The effectiveness of aging contour hedgerows and grass strips for erosion control on an about 15% slope of an Alfisol was compared. The five treatments were Senna siamea hedgerows with tree prunings applied as mulch to crops (H + M), hedgerows with crops with prunings removed (H), mulch only applied to crops (M), crops with Panicum maximum grass strips (G), and a sole crop control of a rotation of maize (Zea mays) and cowpea (Vigna unguiculata).

    The Iberá wetlands, located in La Plata Basin, is a fragile ecosystem habitat of several species of flora and fauna and it also constitutes one of the largest inland freshwater of the world. In this study the hydroclimatologic response to projected climatic changes in the Iberá wetlands is assessed. Bias corrected temperature and precipitation data from four Regional Climate Models (RCMs) developed for the CLARIS-LPB project were used to drive the calibrated Variable Infiltration Capacity (VIC) hydrological model for different time slices.

    The Shangri-La County of the Yunnan Province, SW China, is an economically and ecologically important area. This is especially true for Jiantang that is famous for the Napahai, Bitahai and Shudu Lake wetlands. However, continuing development has threatened the wetland ecosystems and the associated biodiversity in these areas. To better document such changes in land use and their effect on the ecosystem, land use was mapped using a time series of satellite images acquired in 1974, 1993, 2000 and 2012. The results of this survey suggest that forest cover first decreased and then increased.

    The methods and approaches selected in a restoration project depend on the degree of ecosystem degradation and on future land use plans. Programs of monitoring and evaluation must therefore compare restoration progress and effectiveness relative to untreated conditions and to target conditions, particularly with respect to the attributes and functions essential to land use objectives. It is usually not feasible to directly monitor all important forest attributes and functions, so a few indicators must be selected.

    Land use/cover change (LUCC) is a major indicator of the impact of climate change and human activity, particularly in the Sahel, where the land cover has changed greatly over the past 50 years. Aerial and satellite sensors have been taking images of the Earth's surface for several decades. These data have been widely used to monitor LUCC, but many questions remain concerning what type of pre-processing should be carried out on image resolutions and which methods are most appropriate for successfully mapping patterns and dynamics in both croplands and natural vegetation.
