    Resilience-building planning in drylands requires a participatory, integrated approach that incorporates issues of scale (often large scale) and the interconnectedness of dryland ecological and social systems. In an often political environment that supports small, “manageable” administrative units and the decentralisation of power and resources to them, planning at large scale is particularly challenging; development agents in particular may find it difficult to work across administrative boundaries and/or collaboratively.

    The Lawra district of the Upper West region was selected as the case study. This study compared crop yields for FMNR and non-FMNR farmers. FMNR farmers are classified as having at least 8 trees per acre, with an average of 13 trees per acre (33 per ha) and a maximum of 40. Non-FMNR farmers are classified as having between 1 and 7 trees per acre, with an average of 5.Qualitative (focus group discussion) and quantitative (household survey) data were collected in April to May 2019. Over 500 households were interviewed in both CIKOD intervention communities and control sites.

    Meeting the Sustainable Development Goals requires drylands sustainability. Treating drylands as global environmental commons enables better tailored governance responses. Key nested governance elements for drylands involve setting goals, monitoring and delivering sanctions across scales. The present global governance system for drylands only partially delivers these elements. Drylands require a particular focus on linking local and global governance.

    The world’s drylands are among the most vulnerable ecosystems on our planet. Desertification and land degradation are affecting huge land areas, jeopardizing the livelihoods of millions of people. Unsustainable management practices in dryland cultivation and pastoralism have given rise to widespread soil erosion, reduction of the biological production of soils, reduction of vegetation cover, and depletion of surface and groundwater resources.

    The drylands of the world occur on every continent, covering some 41% of the terrestrial surface. One third
    of humanity inhabits these harsh degrading landscapes, eking out a living through adaptive processes that
    have served them well until recent increases of land degradation. Growing pressures from population growth,

    Asia and the Pacific, for the purposes of this book, encompasses a vast territory extending from Mongolia in the north to New Zealand in the south; from the Cook Islands in the east to Kuwait in the west (Map 1). The environmental diversity of Asia and the Pacific is therefore vast, and is contrasted by the region’s coldest and hottest deserts, verdant tropical rainforests, extensive steppe, desert steppe, grassland and rangelands, mountains and plains.

    Change in land management practices and governmental policies is urgently needed to reverse the continuing decline of marginal drylands. Marginal drylands are fragile ecosystems that sustain the livelihoods of millions of poor people in developing countries. However, their capacity to provide these services is continuously declining due to desertification, resulting in dwindling land productivity, and affecting human well-being and development opportunities in many marginal drylands.

    It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept.

    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.

    In a world grappling with the challenges of food insecurity, climate change, landscape degradation, and rural poverty, regreening offers a path forward, especially in dryland areas. The transformation of degraded landscapes—restoring productivity and increasing resilience through the widespread adoption of agroforestry and sustainable land management practices—can deliver food, climate, and livelihood benefits.

    Part I. Introduction
    Part II. How and Where is Regreening Happening?
    Part III. The Impacts Of Regreening
