Growing processing tomatoes represents one of the most intensive forms of land use in terms of water consumption and nutrient inputs. During the last decade in many European countries and in the United States, Integrated Crop Management guidelines have also been applied for fertilisation and reducing nitrogen inputs to crops has become compulsory. A large number of Best Management Practices, rules and tools have been developed to steer farmers toward sustainable farming practices.

The multifunctionality of agriculture promoted by the Agriculture Act is difficult to reconcile with the intensive models dominant in Guadeloupe and Reunion. This is made clear by an analysis of the management rules and practices for territorial farming contracts, intended to implement this Act. The difficulty of this reconciliation can also be observed by the impact that the statute’s application has had on its targets — production units. We conducted open or conversation interviews with institutional personnel and with farmers who have signed these contracts.

There are uncertainties in the definition of phosphorus (P) and nitrogen (N) transfer pathways within agricultural river catchments due to spatiotemporal variations such as water recharge and the farming calendar, or catchment soil and hydrogeological properties. This can have implications for mitigation policies. This study combined detailed pathway studies with catchment integrated studies to characterise N and P transfer pathways for four agricultural catchments with different land management, soil drainage and geology.

This contribution deals with agricultural dynamics in late-Imperial Russia. Based upon a comprehensive micro-level data set on annual yields between 1883 and 1913, we provide insight into regional differences of agricultural growth and the development prospects of Russian agriculture before WWI. Making use of the fact that contemporary Russian statistics distinguished between mostly communally governed open fields and privately owned land, we are able to test the implications of different land tenure systems for agricultural yield growth.

A diagnostic study of the development potential of livestock for the rice-based economy of the Office du Niger (ON) was conducted in Mali. The functioning of selected farming systems and value chains were studied by means of interviews, surveys and farmer group discussions. The findings show that in the ON rice remains the prime agricultural activity; although half of the farm households own cattle (for capital insurance and draught power), livestock management is troublesome because of a lack of grazing land and water points.

Purpose: Why do farmers not take better care of their soils? This article aims to give insight into how farmers look at soil quality management. Design/methodology/approach: It analyses diverse land management practices and visions on soils and soil quality of ten agroecological and 14 conventional smallholder farmers in Araponga, Minas Gerais, Brazil. As agroecological farming (that is, managing soils with minimum use of external inputs) requires more complex knowledge, it is assumed that agroecological farmers would be more knowledgeable on soils compared to conventional farmers.

Higher irrigation quota for conventional farming causes substantial conflicts between water supply and demand in agriculture, and wind erosion near soil surface is one of the major causes of farmland degradation and desertification in arid areas. This research investigated the effect of the amounts of irrigation in combination with tillage practices on soil evaporation (E), water consumption (ET) characteristics, and grain yield performance and water use efficiency (WUE) for wheat (Triticum aestivum L.) intercropped with maize (Zea mays L.) in strip planting in an Oasis region.

Environmental targets are often used in planning for sustainable agricultural landscapes but their impacts are rarely known. In this paper we introduce landscape futures analysis as a method which combines linear programming optimisation with scenario analysis in quantifying the environmental, economic, and social impacts associated with achieving environmental targets, on a landscape scale. We applied the technique in the Lower Murray in southern Australia.

A major reason given for the decline in per capita food production in Nigeria over the last two to three decades is the gradual decline in land productivity. Available information shows that in southern Nigeria, for example, there was recorded a consistent decline in yield per hectare of major food crops between 1995 and 2000. Evidence from the literature suggests that the main reason for this persistent decline in soil productivity is the perpetuation of unsustainable soil management practices by small food crop farmers that dominate the food production landscape in the country.

The rainfall pattern in the Sahel is very erratic with a high spatial variability. We tested the often reported hypothesis that the dispersion of farmers' fields around the village territory helps mitigate agro-climatic risk by increasing yield stability from year to year. We also wished to evaluate whether this strategy had an effect on the yield disparity among households in a village. Based on a network of approximately 60 rain gauges spread over 500km² in the Fakara region (Southwest Niger), daily rainfall was interpolated at 300m×300m resolution over a 12-year period.

Using a nationally representative survey of 263 farm operators in Ireland, this study develops a typology of private forest landowners' objectives for forest ownership. It is important to understand farmers' forest ownership objectives as this will enhance economic analysis in general, but also to formulate more effective policies that take into account the range of motivational profiles of landowners. Using principal component analysis, three core motivations for forest ownership are identified representing economic, lifestyle and multifunctional benefits.
