    This article uses data from household income surveys to look at income structures amongst households in three mountainous regions of Tajikistan: Gorno-Badakhshan, the Rasht Valley and Eastern Khatlon. The structure of incomes demonstrates the dominant role of subsistence agriculture in all three regions although commercial agriculture is important amongst better-off households in Rasht. Relationships between poverty and household characteristics including access to capital, demographic variables and income-generating activities were examined.

    This paper examines the impact of land reform on agricultural productivity in Tajikistan. Recent legislation allows farmers to obtain access to heritable land shares for private use, but reform has been geographically uneven. The break-up of state farms has occurred in some areas where agriculture has little to offer but, where high value crops are grown, land reform has hardly begun. In cases where collectivized farming persists and land has not been distributed, productivity remains low and individual households benefit little from farming.

    Land is very important natural resource to the human being as it provides the basis for more than 95% of human food. On the broader context, land has many other functions, e.g. provision of biological habitats and physical and connective space; regulation of hydrology and climate; storage of minerals, raw materials and historical/pre-historical records; and as a buffer to control waste and pollution. Expanding human requirements and economic activities are placing ever increasing pressures on land resources, creating competition and conflicts and resulting in suboptimal use of land.

    ICARDA witnessed several important developments in 2006. Of these, the Fifth External Program and Management Review (EPMR) was the most significant, as it provided a comprehensive assessment of the Center's global activities, as well as new insights and dimensions that helped refine ICARDA's new Strategic Plan for 2007- 2016. The EPMR coincided with a transition in the governance and leadership of ICARDA.

    El pastoreo del microzooplancton (< 200 m) sobre el fitoplancton, juega un papel importante en la trofodinámica del sistema pelágico. Para determinar la relevancia de este proceso en Bahía Concepción, se utilizaron la clorofila-a estimada por cromatografía líquida de alta resolución (HPLC) y la microscopía para determinar las tasas de crecimiento del fitoplancton y pastoreo por el microzooplancton obtenidas con la técnica de dilución. El crecimiento del fitoplancton y pastoreo por el microzooplancton fue evaluado en la región media de la bahía.

    Livestock systems in developing countries are characterised by rapid change, driven by factors such as population growth, increases in the demand for livestock products as incomes rise, and urbanisation. Climate change is adding to the considerable development challenges posed by these drivers of change. How can livestock keepers take advantage of the increasing demand for livestock products, where this is feasible, and how can the livestock assets of the poor be protected in the face of changing and increasingly variable climates?

    People’s perceptions of their environment

    in high mountain rangelands ultimately

    affect the fragile ecosystems on which

    they depend, and thus their welfare. This is

    especially true in developing countries,

    where the livelihoods of people living in such ecosystems depend on grazing

    livestock. The present study, conducted in the central mountain region of Peru, used photographs and Q methodology to investigate the criteria and preferences that shepherds and local administrators apply in making

    Soil microbial biomass is considered as an important early indicator of changes that may occur
    in the long term with regard to soil fertility and constitutes an important source and sink of nutrients. In
    South Africa, rangeland monitoring has mostly focused on assessing changes of aboveground vegetation
    in response to land uses effects, but the associated changes at belowground soil level remain a topic of
    further research. The aim of this study was to explore soil microbial biomass at three sites under
