Land is a scarce resource increasingly affected by the competition of mutually exclusive uses. Fertile land in rural areas becomes scarcer due to population growth, pollution, erosion and desertification, effects of climate change, urbanization etc. On the remaining land, local, national and international users with different socioeconomic status and power compete to achieve food security, economic growth, energy supply, nature conservation and other objectives. Land use planning can help to find a balance among these competing and sometimes contradictory uses.

This article seeks to draw connections between a political ecology of global investment in resource sector development and a culturally informed understanding of rural out-migration across the Lao–Thai border. The author highlights how the departures of rural youth for wage labor in Thailand and the remittances they return to sending villages are becoming important for understanding agrarian transformations in Laos today. In the first section the author introduces the contemporary context of cross-border migrations across the Lao–Thai Mekong border.

This paper uses data collected in Thailand among permanent rural-urban migrants to analyse the motivations in land temporary transfers such as free loans or rentals. Land transfers are here looked at in a continuum and categorized according to three characteristics: the nature of the relationship between the parties of the exchange, the monetary nature of the payment as well as its explicit or imlicit nature. This methodology allows a richer typology than traditionnally used in empiric literature, and distinguishes between various loans that are not always free.

This study on gender and livelihood aims to find new ways of improving the incomes of rural households, based on the role of women in agricultural production and the division of labor in socioeconomic activities between men and women. It targets eight villages in two regions: Merek (Kermanshah Province) and Honam (Lorestan Province), and was carried out through conducting a social survey (quantitative research) and a participatory rural appraisal - PRA- (qualitative research). The results from qualitative and quantitative research were integrated.

Sustainable management of limited land and water resources is urgently needed to meet the increasing demand for food and to protect the environment. Land suitability analysis is a prerequisite in assessing and proposing sustainable land use alternatives for an area. Soil data are usually available at different levels of detail and stored in various forms, usually soil maps and/or soil observations. Soil data interpretation methods control the reliability of land suitability evaluation results.

The objectives of this report are to evaluate and test, with community participation; the benchmark water management options which sustainably improve water productivity, net return per water unit, and optimize water use. The strategies evaluated have to be economically viable, socially acceptable, and environmentally sound in the three different agricultural eco-systems.

Poverty, food insecurity, natural resource degradation and climate change are global challenges; but they impact most severely on rural communities in dry areas. Addressing these challenges requires a combination of good science, integrated research-for-development approaches, and effective partnerships. As this report illustrates, all three elements are in place, resulting in new technologies and tangible benefits in more than 40 countries.

A crucial part of the Initiative is the determination of the extent and nature of the land degradation
due to salt damage in Central and Southern Iraq. A range of techniques, including the very latest
Geographic Information Systems are being deployed to achieve this.

Dryland (arid and semi-arid) ecosystems occupy more than 41% of global land area and are home to 2.5 billion people. More than 50% of South Asia’s dryland ecosystems are located in India. Drylands contribute about 40% of the total food grain production and support two thirds of livestock population. Despite these important roles, agricultural production systems in the drylands are facing numerous challenges that threaten their resilience and future sustainability. This paper demonstrates some of the challenges and draws implications for priorities research and strategies.

Few regions present bigger development challenges than the African drylands – home to nearly 300 million people, and the vast majority of Africa’s poor. Food security and rural welfare in these areas are limited by a range of factors, biophysical, socio-economic and policy-related. And many of the biggest challenges – poverty, drought, land degradation, food insecurity – will be exacerbated by climate change.
