Over the last decade considerable research has been conducted on the development and the impacts of large-scale economic land concessions for plantations in Laos and Cambodia. These studies have variously illustrated that concessions frequently result in serious negative impacts on local people and the environment, often leading to dramatic transformations of landscapes and livelihoods. As important as this research has been, these studies have largely focused on the immediate impacts of the “enclosure” process associated with gaining access to land by investors.

This research was carried out in a dense tropical forest region with the objective of improving the biomass estimates by a combination of ALOS-2 SAR, Landsat 8 optical, and field plots data. Using forest inventory based biomass data, the performance of different parameters from the two sensors was evaluated. The regression analysis with the biomass data showed that the backscatter from forest object (σ°forest) obtained from the SAR data was more sensitive to the biomass than HV polarization, SAR textures, and maximum NDVI parameters.

The urban transition that has emerged over the past quarter century poses new challenges for mapping land cover/land use change (LCLUC). The growing archives of imagery from various earth-observing satellites have stimulated the development of innovative methods for change detection in long-term time series. We tested two different multi-temporal remote sensing datasets and techniques for mapping the urban transition.

Food availability, access, stability and utilization are all part of the multi-dimensional nature of food security. The “availability” aspect, discussed here, refers to the availability of sufficient quantities of food of appropriate quality, supplied through domestic production or inputs.

Most of the large rice irrigation systems in Southeast Asia have been designed for rice irrigation under a supply-driven mode. Despite their huge contribution to agricultural production, there is a general consensus that these large rice irrigation systems have not lived up to expectations because of a legacy of poor institutional arrangements and system design, degraded infrastructure, poor management and stagnation in the face of rapid transformations of agriculture and pressures on their water supply.

This paper assesses past trends in agricultural land and labour productivity, as a test whether it is feasible to meet the SDG target 2.3, namely doubling productivity and incomes of smallholders within a 15-year time span, if history were to serve as a guide. The target implies agricultural productivity would need to increase by 4.6% per year on average during 2015-2030. Available country-level data on land productivity (1961-2012) and labour productivity (1980-2012) for 140 countries shows that past trends fall well short of the desired pace of productivity growth.

Document de travail sur les régimes fonciers 20. Ce document analyse les caractéristiques des systèmes de propriété communale dans divers pays d’Asie. Les pressions actuelles du marché sur les ressources naturelles créent à la fois des défis et des opportunités pour les communautés et pour les gouvernements en vue d’utiliser et de renforcer les systèmes de propriété commune pour promouvoir la gestion durable des ressources naturelles. Des politiques et des institutions ad hoc sont nécessaires pour promouvoir la redevabilité des acteurs et la bonne gouvernance de ces ressources.
