Agricultural production in Cambodia is concentrated in the northwestern districts bordering Thailand, on the central plains surrounding the Tonle Sap Lake and its river systems, along the Mekong and Bassac rivers towards the Mekong delta, and in the northern and northeastern provinces. In 2012, the total land-use area under major agricultural crops was about 4.015 million ha. Rice is the dominant crop, occupying about 2.968 million ha; non-rice crops are grown on about 1.047 million ha (MAFF 2012).

The type of agrarian structure employed to produce tropical commodities affects many dimensions of land use, such as ownership inequality, overlapping land rights and conflicts, and land use changes. I conduct a literature review of historical changes in agrarian structures of commodities grown on the upland frontier of mainland Southeast and South Asia, using a case study approach, of tea, rubber, oil palm and cassava.

Rural change in Cambodia manifests itself in rapidly declining land availability for the smallholder sector, posing the question of how farmers may be able to deal with limited access to land. In this paper, we discuss with a case study village and household livelihood strategies of smallholders currently operating under land-constrained conditions. Based on an integrated assessment of a smallholder village in Kampot province, we illustrate in quantitative terms how land shortage is creating problems of surplus generation and liquidity issues in monetary and non-monetary flows.

Cambodia is engaged in profound societal and economic changes usually referred to as “agrarian transition”.

For centuries, farmers in the mountainous region of mainland Southeast Asia have practiced shifting cultivation, with plots of land cultivated temporarily and then allowed to revert to secondary forest for a fallow period. Today, more than one million hectares have been converted to rubber plantation. By 2050, the area under rubber trees in the montane regions of Cambodia, Laos, Myanmar, Thailand, Vietnam, and China's Yunnan Province is predicted to increase fourfold.

This briefing note presents the findings of seven case studies conducted from May to June 2014. The studies were conducted in Bangladesh, Cambodia, India, Indonesia, Laos, Nepal and Thailand and looked into the livelihood and food security among indigenous shifting cultivation communities in South and Southeast Asia. The briefing note provides a summary of the main findings of the case studies and the common recommendations from a multi-stakeholders consultation held August 28-29 in Chiang Mai, Thailand.

Despite the many transformations taking place in Myanmar, its agricultural sector is lagging. A high proportion of rural households remain poor and food insecure as a result. This article examines the underlying causes of poor agricultural performance through a combination of literature and secondary data review combined with extensive field interviews with a broad range of key informants in the main agricultural zones of the country. We identify key structural changes that are needed to unleash smallholder-led agricultural transformation and broad-based rural economic growth.

ABSTRACTED FROM EXECUTIVE SUMMARY: The Qualitative Social and Economic Monitoring of Livelihoods in Myanmar (QSEM) research program provides a descriptive picture of rural life in Myanmar.

The potential of feed-food double-cropping was evaluated at Ginchi, Ethiopia, for two years with the objective of evaluating herbage yields of fodder crops and the subsequent effects on grain yields of chickpea and grass pea. Early maturing oat (79Ab382 (TX) (80SA95); 79CP84 (Coker SR. res) 80SA130; SRCP X 80Ab2806; C7512/SRCP X 80Ab 2252 and CO X SRCP X 80Ab2291) and common vetch (Acc. No. 2490; Acc. No. 2742) were selected and planted on lands reserved for chickpea/grass pea at the start of the main rainy season.

This paper presents a case study of land-use/land-cover (LULC) changes from 1975 to 2014 in the central highlands of Ethiopia and traces out its impact on socioeconomic conditions of the local community in the study area. We used four time series Landsat satellite images, that is, Landsat MSS (1975), Landsat Thematic Mapper (1986), Enhanced Thematic Mapper (2000), and Landsat 8 OLI scenes (2014), to investigate the changes in LULC.

Much of the biodiversity‐related climate change impacts research has focused on the direct effects to species and ecosystems. Far less attention has been paid to the potential ecological consequences of human efforts to address the effects of climate change, which may equal or exceed the direct effects of climate change on biodiversity. One of the most significant human responses is likely to be mediated through changes in the agricultural utility of land.
