    Iran

    The growing population and increasing socio-economic necessities creates a pressure on land use/land cover. Nowadays, land use change detection using remote sensing data provides quantitative and timely information for management and evaluation of natural resources. This study investigates the land use changes in part of Hableh Rood Watershed of Iran using Landsat 7 and 8 (Sensor ETM+ and OLI) images between 2001 and 2013. Supervised classification was used for classification of Landsat images.

    Japon

    Japan's forest industry operates in mountainous regions rather than hilly areas. The forest road density is also low, and it is not easy to develop new roads and maintain them. Therefore, the work of moving about and transporting heavy loads over irregular mountain forest terrain far from roads is still hard labor performed by humans. Even today, a little technical development has been done to assist in this work.

    Europe

    In Europe, grassland is one of the dominant forms of land use. Within 20 years, the area of permanent grasslands and pastures in Western Europe has declined by 12%. Semi-natural grasslands are often hot spots of biodiversity and are threatened both by intensive farming and by the abandonment of farmland in marginal areas. In this review, we show that biodiversity, climate change, C sequestration and farming systems issues are highly interconnected in grassland ecosystems.

    Life Cycle Assessment (LCA) is a robust tool often used for eco-design. It allows the assessment of environmental impacts, at a global scale, accounting for all stage of a product life cycle, “from cradle to grave”. There is a methodological gap in this method to account for occupation and transformation impacts in marine ecosystems due to human activities. The task accomplished during this PhD is the development of a methodological framework for a new impact category in LCA to overcome this lack: the sea use. The general framework for sea use had to be defined.

    Guatemala, Honduras, Amérique centrale

    The presence of trees in the farms is typically considered a good practice in water shed  management. Therefore, it was examined the voluntary adoption of land uses considered more compatible with the water ecosystem service (shade coffee and woodland) in the region of Trifinio (located in Honduras and Guatemala), where there is not given any incentives or payment for this environmental service. It was observed low adoption of these land uses on small farms.

    Resource structure in the observed countries, who belong to different agriculture types expressed through relationship land/work ratio, indicates significant variations. Different resource supply is crucial in determining the level of productivity of labor and land in agriculture, and therefore, affects the competitiveness of agriculture, the competitiveness of an entire national economy as well.

    Pakistan

    A study was conducted in Sargodha, Pakistan during the year 2011 to testify irrigation practices as a method for reclaiming salt affected soil. Field experiments were conducted on saline-sodic and uncultivated land divided into 12 field plots. Six irrigation treatments, each replicated on two field plots, were applied to test the responses of soil and wheat crop yield.
