    Three smallholder villages located in typical communal (from 1948), old (1987) and new (2002) resettlement areas, on loamy sand, sandy loam and clay soils, respectively, were selected to explore differences on natural resource management and land productivity. Focus group discussions and surveys were carried out with farmers. Additionally, farmers in three wealth classes per village were chosen for a detailed assessment of their main production systems.

    The design of public policy related to irrigation sectors in North Africa was often based on the state view. Local farmers' organizations, made up of family farms, did not contribute to building the legal framework, which was in turn unable to propose specific solutions for family farming. Legal reforms currently underway in Morocco and Algeria show how difficult it is to integrate field realities. Access to land and water resources is often obtained through informal local coordination modes.

    Soil quality (SQ) assessment from farmers' point of view can be used as a primary indicator for planning sustainable agriculture. Despite this fact, limited information is documented with regard to SQ indicators, for example weed species, crop types and management practices from farmers' knowledge perspectives. The aims of this study are to analyse factors that determine farmers' knowledge of SQ, identify SQ indicators of weed species and crop types across different SQ status and assess soil‐and‐crop management practices that maintain SQ in the Mai‐Negus catchment, northern Ethiopia.

    The effects of soil bunds on runoff, losses of soil and nutrients, and crop yield are rarely documented in the Central Highlands of Ethiopia. A field experiment was set up consisting of three treatments: (i) barley‐cultivated land protected with graded soil bunds (Sb); (ii) fallow land (F); and (iii) barley‐cultivated land without soil bund (Bc). For 3 years (2007–2009), the effect of soil bunds on runoff, losses of soil and nutrients, and crop productivity was studied.

    A major development concern of the 1970s and 1980s was 'the other energy' or 'woodfuel crisis'. Woodfuel use in developing regions of Africa, Asia, and Latin America was believed to be a key factor in tropical deforestation, and the loss of forests was projected to result in widespread woodfuel shortages. In recent years, however, it has become apparent that woodfuel production is seldom a direct cause of deforestation (although it may be a by-product), and that most woodfuel demand is met by trees and shrubs growing outside of forest areas.

    Game changers to achieve sustainable intensification of agriculture are possible in the irrigation sector and they focus mainly on getting more with less. There is, however, still a long way to go to replicate, adapt and develop approaches to take such ideas to scale and increase productivity within existing agricultural water management contexts.

    In this paper, the role of subsurface drainage in irrigated agriculture in semi-arid and arid regions is discussed based on experiences obtained in Egypt, India and Pakistan. Agriculture in these countries is predominantly practiced by small, marginal farmers with landholdings of often less than one hectare. In general, they do not have the means to pay for the investments in irrigation and drainage themselves. Consequently, most irrigation and drainage projects are funded by the (local) governments.

    Algeria

    The use of groundwater in irrigated agriculture is often regarded as an effective way of increasing farm productivity. However, the effects of differential access to groundwater by farmers have rarely been studied at the microeconomic scale, particularly the possibly negative effects of marginalization of small farmers. During the hydraulic crisis that has affected Algerian irrigation schemes since the 1980s, groundwater has become a major source of irrigation for farmers. A process of farm differentiation occurred linked to farmers' access to groundwater, causing social inequity.
