Although many contemporary studies of agriculture associate larger properties with higher relative productivity, this assumption has limited relevancy for the analysis of situations in which property owners profit more from large-scale property accumulation itself rather than any superiority in exploitation opportunities offered by increased size. In Brazil, the efficiency-of-scale paradigm has been used to criticize peasant agriculture as unproductive and hide contradictions deriving from land concentration.

Fertile soils are an essential building block for human existence on Earth. The degradation of soils and land, in this regard, poses significant challenges for the well-being and food security of all the people around the world. Moreover, soils provide not only food, fiber, and many types of biomass we use, but also a wide

Groundwater is an increasingly important resource for urban and rural potable water supply, irrigated agriculture, and industry, in addition to its natural environmental role of sustaining river flows and aquatic ecosystems. But major changes in land use that impact groundwater are taking place, as a consequence of population growth, increasing and changing food demands, and expanding biofuel cultivation. The link between land use and groundwater has long been recognised, but has not been widely translated into integrated policies and practices.

The publication presents updated and new analyses of land, labor, and total productivity trends in African agriculture. It brings together analyses of a unique mix of data sources and evaluations of public policies and development projects to recommend ways to increase agricultural productivity in Africa.

As investments in nature are needed more than ever, and are increasingly gaining traction, the challenge is to identify environmental and social risks and to demonstrate positive impacts associated with investing in nature-based projects in a standardized and comparable manner. To help create a clear track record of projects that can be assessed on risk-return-impact profiles, a certain degree of standardization is needed, while maintaining scientific rigor.

Most commonly in drylands the salinity levels are always high and evenly dispersed due to this salinity levels the plant cultivated are usually tremendously affected. Normal plants cannot grow in soils with high salinity levels. In this book the authors would like to analyze the effects of human acticities on the salinity lebvels in drylands.

With an expected 9.5 billion people living on earth by 2050, population pressure, higher consumer expectations and climate change will tax and degrade our natural resource base, especially the LAND. With an increasing awareness of the potential of land to meet public and private development goals, land is being seen as an ever more attractive investment vehicle.

This paper explores the role of the global food system as the principal driver of accelerating biodiversity loss. It explains how food production is degrading or destroying natural habitats and contributing to species extinction. The paper outlines the challenges and trade-offs involved in redesigning food systems to restore biodiversity and/or prevent further biodiversity loss, and presents recommendations for action. The paper introduces three ‘levers’ for reducing pressures on land and creating a more sustainable food system.

In the last decade, there have been a number of global/regional targets and initiatives to halt and reverse land degradation and restore degraded land. Starting in 2010, these include the CBD’s Aichi Biodiversity Targets, one of which aims to restore at least 15% of degraded ecosystems; the Bonn Challenge and its regional initiatives to restore more than 150 million hectares; and most recently the 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs).

Land degradation is a pervasive, systemic phenomenon: it occurs in all parts of the terrestrial world and can take many forms. Combating land degradation and restoring degraded land is an urgent priority to protect the biodiversity and ecosystem services vital to all life on Earth and to ensure human well-being

This publication introduces SLM and its principles and presents how good SLM practices in Bosnia and Herzegovina were documented, evaluated, selected and scaled through participatory land use planning processes. High demand for agricultural products and raw materials produced on land is under adverse social and economic conditions and a lack of adequate investment.

The pressure on land is growing in many regions of the world, due to the increasing demand for arable crops, meat and dairy products, bio-energy and timber, and is exacerbated by land degradation and climate change. This policy report provides scenario projections for the UNCCD Global Land Outlook, exploring future changes to the use and condition of land and the resulting impacts on food, water, climate change and biodiversity.
