Highlights •Effective climate change adaptation measures must consider farmer knowledge. •A case study of 132 small-holder farmers in regional North-West Cambodia was used. •Farmers were aware of adaptation practices to cope with anticipated climate changes. •Incomplete knowledge and resources meant they were reluctant to apply the practices. •The methodology used is…

The paper addresses the new competition for land arising from growing and changing demand for food when combined with increasing global demand for transport energy, under conditions of declining petro-chemical resources and the urgent need to reduce greenhouse gas emissions. The paper starts from the premise of a ‘food, energy and environment trilemma’ (Tilman et al., 2009), where all demands to…

Challenges to global food security are: (i) population increase from 7 billion in 2011 to 9.2 billion in 2050, (ii) climate change, (iii) soil degradation by erosion, salinization, organic matter and nutrient depletion, and elemental imbalance, (iv) decreased availability of water, (v) land competition for urbanization, brick making, biofuel, and non-agricultural uses, and (vi) preferences toward…

Many pathways have been proposed for including land use in a post-2012 climate agreement. Several involve new accounting structures which are quite different from the rules established in the Marrakech Accords and related decisions. However, a mechanism based largely on the structure agreed for the first commitment period also has its benefits. This paper discusses the weaknesses of the current…

This chapter sets out to present a short review of (i) the general context of land degradation under the framework of UNCCD – the international convention on desertification with a specific focus on Land Degradation Neutrality, and (ii) examples of the main processes responsible for soil degradation (e.g. surface crusting, runoff and water erosion, tillage erosion, wind erosion, and…
