    This issue of Caravan describes the new program, and some of the research innovations it will build on.

    Soil organic carbon (SOC) and rainfall are generally
    positively related, whereas a negative relationship
    between soil inorganic carbon (SIC) and rainfall with
    some exception is observed. Land use pattern in black
    soil region (BSR) of the semi-arid tropical (SAT)
    India, consists of 80% under agriculture, followed by
    forest, horticulture, wasteland and permanent fallow.
    For sustainable agriculture on these soils, there is a
    concern about their low OC status, which warrants
    fresh initiatives to enhance their OC status by suitable

    The Karkheh River Basin (KRB) of Iran has a semi-arid to arid climate and suffers from low rainfed agricultural productivity. Supplemental irrigation (SI) is recommended in the upper KRB to increase crops yields and water productivity (WP). However, development activities upstream will certainly affect the water quality and quantity flowing to the Karkheh Dam downstream.

    Agriculture is a major contributor to climate change,
    emitting the three major greenhouse gases (GHGs) –
    carbon dioxide (CO2), methane and nitrous oxide – into the
    atmosphere. According to the Fifth Assessment Report of
    the Intergovernmental Panel on Climate Change (IPCC),
    the Agriculture, Forestry and Other Land Use sector “is
    responsible for just under a quarter (~10–12 Gt CO2eq/yr) of
    [all] anthropogenic GHG emissions mainly from deforestation
    and agricultural emissions from livestock, soil and nutrient

    Property rights are a cornerstone of economic development and social justice. A fundamental way of understanding the strength of property rights is through citizens' perceptions of them. Yet perceptions of tenure security have never been collected at a global scale.

    Successive governments in India have emphasized the need for industrial expansion and privatization as the foundation for economic stability and growth. This focus has led to the policy-induced transformation of rural and peri-urban landscapes into use for industry and infrastructure. These transformations have caused social conflicts and ecological impacts for land and resource-dependent people.

    Urban sprawl has become a remarkable characteristic of urban development worldwide in the last decades. Urban sprawl refers to the extent of urbanization, which is a global phenomenon mainly driven by population growth and large scale migration. In developing countries like Iran, urban sprawl is taking its toll on the natural resources at an alarming pace. The purpose of this paper is to study urban growth and effective factors on them in the city of Urmia, Iran. We used quantitive data of the study area from the period between 1989 and 2007, and population censuses of Urmia.

    Urban footprint refers to the proportion of paved surface (built up, roads, etc.) with the reduction of other land use types in a region. Rapid increase in the urban areas is the major driver in landscape dynamics with the significant erosion in the quality and quantity of the natural ecosystems. The urban expansion process hence needs to be monitored, quantified and understood for effective planning and the sustainable management of natural resources.
