    One of the main technical knowledge gaps for sustainable timber production in tropical forests is the lack of reliable information on tree growth, which is indispensable for defining cutting cycles and estimating harvest volumes. We applied dendroecological methods to measure and model the diameter growth (dbh) of mahogany Swietenia macrophylla and cedar Cedrela odorata in humid tropical forests of community-managed concessions in the Maya Biosphere Reserve, Petén, Guatemala. The width of growth rings was determined in increment cores from 32 trees of S. macrophylla and 27 of C.

    Irrigation has a large potential to increase agricultural output and yield per unit area. However, the long term sustainability increased production, together with degradation of the soils (and associated water bodies) in irrigated areas may be irreparably damaged by inappropriate watering schedules. In Ethiopia, surface and groundwater irrigation has been promoted intensively throughout the country. While many projects focus on individual or scheme level water access, very little is known about the sustainability of irrigation in Ethiopia.

    Background: ‘Climate-smart agriculture’ (CSA)—agriculture and food systems that

    sustainably increase food production, improve resilience (or adaptive capacity) of farming

    systems, and mitigate climate change when possible—has quickly been integrated into the

    global development agenda. However, the empirical evidence base for CSA has not been

    assembled, complicating the transition from CSA concept to concrete actions, and

    contributing to ideological disagreement among development practitioners. Thus, there is an

    A number of studies have suggested that addressing greenhouse gas (GHG) emissions from agricultural

    production, or ‘supply-side emissions’, will be insufficient to reduce agri-food sector GHG emissions to limit

    the increase of global temperatures to well below 2o

    C. Recent studies have also suggested that ‘demandside

    measures’ related to food consumption, food value chains, and food loss and waste, will be necessary

    to reduce emissions and may have a larger technical mitigation potential than supply-side measures.

    The Crop Ontology is a service of the Integrated Breeding Platform (www.integratedbreeding.net) in collaboration with the CGIAR and partners and under the leadership of Bioversity international. The Crop Ontology (www.cropontology.org) provides harmonized and validated breeders’ trait names, measurement methods, scales for currently 18 crops that are used by the Breeding Management System (BMS).

    This report is aimed at readers who seek to build economic evidence in support of the inclusion of actions on agriculture in climate change plans and programmes, particularly at the national level under the umbrella of nationally determined contributions (NDCs) to the December 2015 Paris Agreement, which aims to restrict a rise in global temperatures and manage risks.

    This working paper examines the development of regional socioeconomic scenarios for West Africa’s development, agriculture, food security and climate impacts. We present four globally consistent regional scenarios framed and outlined by regional experts who crafted narratives and determined key drivers of change. Stakeholders identified the type of actors driving change and the timeline of strategic planning as the most uncertain and most relevant factors of change affecting food security, livelihoods and environments in the region.
