    Time series of vegetation indices (VI) derived from satellite imagery provide a consistent monitoring system for terrestrial plant productivity. They enable detection and quantification of gradual changes within the time frame covered, which are of crucial importance in global change studies, for example. However, VI time series typically contain a strong seasonal signal which complicates change detection. Commonly, trends are quantified using linear regression methods, while the effect of serial autocorrelation is remediated by temporal aggregation over bins having a fixed width.

    Trade liberalisation processes impact differently on men and women due to the fact that men and women have different roles in production. Despite the fact that women are actively involved in international trade, WTO agreements are gender blind and as such have adverse impacts on women. The General Agreement in Trade and Service (GATS), for instance, provides for a level playing field in service provision between big foreign owned companies and small locally owned companies.

    Recent increases in the level of agricultural commodity prices and the resulting demand for land has been accompanied by a rising interest in acquiring agricultural land by investors. This paper studies the determinants of foreign land acquisition for large-scale agriculture.

    Empirical studies have shown that oil-dependent countries are more likely to suffer from civil wars motivated by ‘grievances’ or ‘greed’ — and this is particularly true for states in sub-Saharan Africa.

    In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production. While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare) per millimeter of rainfall—also drives production.

    Drought is one of the major climatic hazards impacting on the various sectors including crop and livestock in the West African Sahel. Pastoral and agro-pastoral communities in the region are regularly affected by drought, with vulnerability differing with gender, age, wealth status (access to cropland and livestock endowment), geographic location, social networks, and previous exposure to drought. Effective interventions require regular monitoring of vulnerability to drought, for which various quantitative and qualitative approaches exist.

    IN response to an on-line survey, 76 project leaders and staff gave CPWF Phase 1 a

    generally favorable review. Respondents came from 68 CPWF projects in 45 countries on

    three continents. The survey sought to help learn what went well in Phase 1, what did not

    go so well and can be improved in Phase 2.

    Nearly three-quarters of respondents felt that they had achieved different research results,

    outcomes and impacts as a result of participation in the CPWF than otherwise possible from
