Food-for-work (FFW) programs are commonly used both for short-term relief and long-term development purposes. This paper assesses the potential of FFW programs to reduce poverty and promote sustainable land use in the longer run. There is a danger that such programs distort labor allocation or crowd out private investments and therefore have unintended negative effects. We explore this issue using survey evidence from northern Ethiopia that we use to motivate a simple theoretical model, a more detailed version of which we then implement through an applied bio-economic model calibrated to northern Ethiopia. The analysis explores how FFW project outcomes may depend on FFW project design, market conditions, and technology characteristics. We show that FFW programs may either crowd out or crowd in private investments and highlight factors that condition whether FFW promotes or undercuts sustainable land use.

Investments to promote sustainable land-use within critical river catchment areas are often undertaken to provide benefits to society. Investments generally aim to protect or restore ecological infrastructure—the underlying framework of ecosystems, functions and processes that supply ecosystem services—for multiple benefits to society. However, the empirical evidence base from studies across the world on both mechanisms and outcomes to support these assumptions is limited. We collate evidence on the benefits of ecological infrastructure interventions, in terms of ecosystem services provided to society, from three major South African water-providing catchments using a novel framework. In these catchments, millions of US Dollars' worth of investments have been made into ecological infrastructure since 1996. We ask the question: is there evidence that ecological infrastructure interventions are delivering the proposed benefits? Results show that even in catchments with substantial, long-term financial investment into ecological infrastructure, research has not empirically confirmed the benefits. Better baseline data collection is required, and monitoring during and after ecological infrastructure interventions, to quantify benefits to society. This evidence is needed to leverage investment into ecological infrastructure interventions at scale. Investment at scale is needed to transition to more sustainable land-use to unlock greater benefits to nature and people.

The severity of permanent damage caused by Cyclone Bola to an estimated 65 000 ha in northern Hawke's Bay is of sufficient magnitude to necessitate complete changes in land use over that region as a whole. Traditional responses to this problem have included a range of incentives which have been principally designed to ensure the continuation of the existing pastoral use. Recent studies have emphasised the need to rationalise land use on the basis of long term sustainability. The costs of facilitating and permanently establishing this change in land use will be high, and an appropriate sponsor must be found, as market forces and commercial enterprise alone will have insufficient incentive to effect the changes.

An ongoing, trinational project is providing the first environmentally sustainable economic development plan for the Ussuri River watershed (URW) in Far East Russia and northeast China. The URW is host to a unique mix of northern taiga and southern subtropical biota, and contains many endemic, relict, and highly threatened species of plants and animals. In Russia, severe monetary inflation and a shift to a market economy have left some aspects of forest biodiversity in jeopardy, particularly policing for wildlife poachers, regulating CITES (international wildlife trafficking) violations, ensuring long-term sustained production of timber and non-timber forest products, protecting unique habitats, and adequately staffing scientific reserves and funding needed research. In China, broad scale conversion of remaining wetlands to agriculture and rice paddies, and of diverse native forests to intensively managed, monocultural plantations, is helping to sustain the economy but is sacrificing biodiversity. A proposed sustainable land use plan has (1) mapped resource use areas, including both proposed and existing transborder nature areas, (2) encouraged foreign investment in both countries, and (3) encouraged sustainable development of natural resource markets that will be compatible with long-term conservation of biodiversity. A hallmark of this plan is integrating the needs of the people with the capacity of the land through both environmental protection and wise resource use. Key words: Russia, China, Far East, Ussuri River watershed, biodiversity, sustainable, land use plan, wildlife

Soil quality represents the ability of the soil to secure environmental functions in a particular way of using it. Health of soil expresses protection and increasing biological productivity, environmental quality and health promotion of all living forms, including humans. This study presents the results of long-term monitoring and evaluation of selected parameters of soil in terms of sustainable land use in the marginal areas of the northeastern Slovakia During 1997–2013 (48º57'N, 20°05'E). Physical (bulk density, porosity), chemical (pH, anorganic nitrogen, available phosphorus, potassium, magnesium and organic carbon content) and biological (soil enzyme activity – urease, alkaline and acid phosphatase) soil properties and available heavy metal content (Cd, Pb and Ni) were monitored and statistically evaluated. The results show that in assessing the quality of soil and environmental pollution of soil the microbial parameters (activity of soil enzymes) appear to be useful. These parameters rapidly respond to environmental stress and can lead to changes in physical and chemical properties leading to early detection of soil degradation.

Strategic spatial planning (SSP) represents a consolidated long-term governance practice across developed and developing countries. It articulates sectoral policies, and it involves vision making and an array of stakeholders regarding land use and development issues around urban and rural territories. Land-use frontiers are territories with abundant land for agriculture and forestry, availability of natural resources relative to labor or capital, and rapid land-use change, often driven by large-scale investments and capitalized actors producing commodities for distal markets. Among various reasons, one of the objectives of SSP processes is to articulate a more coherent and future-oriented spatial logic for sustainable land-use patterns, resource protection and investments. SSP may thus constitute a useful approach to address some of the challenges posed to the governance of land-use frontiers, thus far, its potential contribution in land-use frontiers lacks an explicitly exploration. Here, we examine how SSP can play a role in governing land-use frontiers, through a case-study analysis of Mozambique as an emerging investment frontier. We gathered empirical evidence by interviewing experts involved in resource management, planning and strategizing territorial development in the country, complemented by a content analysis of literature and policy documents. We show that emerging land-use frontiers face several challenges, such as transnational land deals and intensification of commercial plantations. Interview data show that Mozambique lacks a strategic territorial vision, and the short-termism of political cycles hinders long-term territorial development, primarily in rural areas with plentiful land. Our analysis shows that SSP processes could contribute to address both global and country-specific challenges such as poverty traps and land degradation spirals, if various local and distant actors join forces and marry interests. We conclude by presenting a systematic framework explaining how SSP could play a role in governing emerging land-use frontiers for sustainable pathways.

Based on long-term studies of the Don delta and the Manych valley in the area of scientific expedition hospitals of the SSC RAS, the conditions that determine the current state and patterns of soil development in the region, as well as changes in the structure of soil cover under increasing anthropogenic load in the modern period are studied. The analysis of the development of degradation processes in modern land use conditions is presented. Five zones are identified according to the degree of development of degradation processes.

Abstract This paper aims to improve the understanding of environmental and socioeconomic drivers on land use change (LUC) through public participation (PP), and provide recommendations for long-term policy making to support sustainable land use management. Public participation (PP) was necessary to help understand and address the problem and concerns of stakeholders within the study area. Through two collaboration workshops seven individual future land use scenarios were created. Using the FLUS (Future land use simulation) model, land use was projected up till 2060, after which logistic regression analysis took place to find the most significant driver. Results found that LUC within the baseline scenario and the ones chosen by stakeholders were very different, however concluded that Paddy field extent would decrease in the future to be replaced by more drought resilient agriculture; Perennials & Orchards and Field Crops. Outcomes from future scenarios propose that future LUC was driven by environment spatial factors such as elevation and climate, not soil suitability. With, first hand interviews suggesting it is indirect external factors such as, crop price that drive LUC. Overall the study provides steps towards dynamic LUC modelling where future scenarios have been tailored to details specified by the public through their participation.

The expansion of agricultural frontiers in Brazil has caused substantial changes in land use and land cover. This research aims to analyze the space-time dynamics of soybeans and cattle production in the Brazilian territory during the period 1991–2015. The spatial analysis adopted the following procedures: (a) The change vector from the annual calculation of the midpoint of production; (b) mapping of the growth and acceleration rates of the two productions, and (c) mapping of the correlation between the time series of soybean and cattle. The results showed high rates of growth and acceleration for soy production in the South, Central-West and Matopiba regions. The growth acceleration rate identified the long-term deviations that characterized the effective soybean and cattle expansion areas. The results demonstrated the effects of Brazil’s soy moratorium contained soybean expansion into the Amazon region. However, as a side effect, the soybean production replaced cattle production in the savanna region, which in turn, migrated to the Amazon rainforest. Therefore, the present study highlights the importance of public policies that comprehensively understand the spatial-temporal dynamics of Brazilian agriculture to promote sustainable land-use practices.
