A quarterly news bulletin dedicated to the exchange of information relating to wildlife and national resources management for the Asia-Pacific region.
Drainage of agricultural land is one of the most critical water management tools for the sustainability of productive cropping systems, as frequently this sustainability is extremely dependent on the control of waterlogging and soil salinization in the rootzone of most crops. On some…
Este informe está dirigido a revisar y resumir la información existente sobre el secuestro de carbono, con el fin de analizar como los recursos disponibles y los programas específicos se pueden implementar en las tierras áridas que constituyen las regiones con mayor degradación del suelo en…
Bioenergy sits at the intersection of three of the world’s great challenges - energy security, climate change, and poverty reduction - and has received an enormous amount of attention in the past few years. Joint work on these issues is vital considering that together, the G8 +5 Countries…
The performance of many canal irrigation delivery systems is unsatisfactory in terms of: (i) water resources management; (ii) service to irrigated agriculture; and (iii) costeffectiveness of infrastructure management. In recent years, participatory approaches and management transfer reforms…

Soils represent a fundamental abiotic parameter in defining the characteristics of an ecosystem. The U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) produces the most detailed digital spatial soil datasets that are publicly available. The Soil Survey…
We used data available from the literature and measurements from Baltimore, Maryland, to (i) assess inter-city variability of soil organic carbon (SOC) pools (1-m depth) of six cities (Atlanta, Baltimore, Boston, Chicago, Oakland, and Syracuse); (ii) calculate the net effect of urban land-use…
Demographic changes introduced by migration strongly affect economic activities and may thus trigger land-use changes. Migration has been usually overlooked in land use change modelling, even though it is recognized as a dominant demographic factor that influences land use. This paper analyzes…
State forestry best management practice (BMP) programs have been widely developed and implemented to prevent nonpoint source water pollution in the past three decades. The unanswered question is how forestry BMPs have affected the welfare positions of consumers, mills, loggers, and forest…
