Smallholders, food security, and the environment

Reports & Research
Noviembre, 2013
Global

There are 1.4 billion poor people living on less than US$1.25 a day. One billion of them live in rural areas where agriculture is their main source of livelihood. The ‘green revolution’ in agriculture that swept large parts of the developing world during the 1960s and 1970s dramatically increased agricultural productivity and reduced poverty. Many of the productivity gains accrued to smallholder farmers, supported through research and extension services.

Economics of Land Degradation Initiative: Report for policy and decision makers

Considering the figures given in the foreword and found in the literature about the on-going and increasing degradation of land and land-based ecosystems and their productivity, this indicates a pressing need to re-design current policies and clearly defined guidance for future action for sustainable land management.

Experiences in monitoring and assessment of sustainable land management

Journal Articles & Books
Diciembre, 2011

Although sustainable land management (SLM) is widely promoted to prevent and mitigate land degradation and desertification, its monitoring and assessment (M&A) has received much less attention. This paper compiles methodological approaches which to date have been little reported in the literature. It draws lessons from these experiences and identifies common elements and future pathways as a basis for a global approach. The paper starts with local level methods where the World Overview of Conservation Approaches and Technologies (WOCAT) framework catalogues SLM case studies.

ACTION LEVERS FOR A SUSTAINABLE FARMLAND MANAGEMENT IN NIGER

Níger

This study aims to contribute to the understanding of factors influencing the sustainable farmland management in Niger. Specifically, it examines the determinants of adoption of sustainable land management practices including measures to combat erosion, and the use of manure, residues and fertilizer with a view to support the formulation of efficient land use policies based on evidences given fact that the impact of factors influencing farmland management appears to be specific to each context.

Vegetation cover reduces erosion and enhances soil organic carbon in a vineyard in the central Spain

Journal Articles & Books
Diciembre, 2013
España

Land degradation, and soil and nutrient loss, are significant environmental problems in semi-arid agricultural environments in the Mediterranean Basin. One land use that is particularly associated with the highest rates of erosion in Spain is extensive vineyards. We examined the effectiveness of two cover crops for improving soil physical properties and reducing erosion in a vineyard located in the Henares River basin southeast of Madrid, Spain.

Land Degradation Analysis on Coastal Area of Ampara District

Journal Articles & Books
Octubre, 2013
Sri Lanka

The island of Sri Lanka is free from serious natural hazards such as volcanic activity and earthquakes resulting from climatic extremes, but there are impacts of many natural disasters, such as landslides, floods and droughts, the intensity and frequency of which are increasing due to human interventions. Some areas of Sri Lanka are also periodically subject to cyclones that occur due to climatic conditions and geographical locations.Land degradation denotes all natural or anthropogenic processes that diminish or impair productivity of land.

Use of geoprocessing in the study of land degradation in urban environments: the case of the city of São Carlos, state of São Paulo, Brazil

Journal Articles & Books
Diciembre, 2007
Brasil

This paper presents a methodology for the geological engineering survey of land degradation in urban environments using both remote sensing and geoprocessing tools. The area under study was the city of São Carlos, state of São Paulo, Brazil (urban and expansion area). The data presented here were obtained from earlier studies, photointerpretation and geological engineering mapping. The Envi 4.1 software package was used to prepare the digital orthophotos that served as a reference base for the information.

Towards a World Desertification Atlas. Relating and selecting indicators and data sets to represent complex issues

África

Mapping land degradation and desertification (LDD) at the global scale still is a conceptual and operational challenge. The present study has been performed in the frame of the WAD (new World Atlas of Desertification) initiative. The objective of the paper is to test a structured procedure to identify relevant indicators for an effective representation of complex global LDD issues, based on available data sets (both geo-spatial and statistical), and conform to the UNCCD (United Nations Convention to Combat Desertification) requirements.

Temporal Variations of Flow–sediment Relationships in a Highly Erodible Catchment of the Loess Plateau, China

Journal Articles & Books
Diciembre, 2016
China

The flow–sediment relationship is important to understand the soil erosion and land degradation processes in severe eroded areas. This study researches on variations of streamflow, sediment load, and flow–sediment relationship on multi‐temporal scales (annual, flood season and, monthly scales) in a highly erodible catchment of Chinese Loess Plateau.

Mapping Changes in Land Cover Composition and Pattern for Comparing Mediterranean Rangeland Restoration Alternatives

Journal Articles & Books
Diciembre, 2016

The limited amount of studies addressing the long‐term effectiveness of restoration actions to combat land degradation is a constraint for current landscape restoration planning and implementation. Remote sensing data provide a unique opportunity for gathering information on the spatial and temporal variability of restoration processes and may contribute to fill this knowledge gap.
