This guide describes two of the main approaches to greenhouse gas mitigation planning in developing countries: Low-Emission Development Strategies (LEDS) and Nationally Appropriate Mitigation Actions (NAMAs). It explains the possible relationships between them and their status within the United Nations Framework Convention on Climate Change (UNFCCC). National mitigation planning processes have policy, technical and institutional dimensions that need to be addressed in an integrated and iterative manner. For each of these dimensions four key elements are outlined.

This report is a shorter version of World agriculture: towards 2015/2030, FAO's latest assessment of the long-term outlook for the world's food supplies, nutrition and agriculture. It summarizes the projections, distills the messages and presents them for the generalist. The projections cover supply and demand for the major agricultural commodities and sectors, including fisheries and forestry. This analysis forms the basis for a more detailed examination of other factors, such as nutrition and undernourishment, and the implications for international trade.

Using detailed household-farm level data from Malawi, we measure real farm total factor productivity (TFP) controlling for a wide array of factor inputs, land quality, and transitory shocks. We nd that factor inputs are roughly evenly spread among farmers: operated land size and capital are essentially unrelated to farm TFP implying a strong negative eect on aggregate agricultural productivity. A reallocation of factors to their ecient use among existing farmers would increase agricultural productivity by a factor of 3.6-fold.

This paper examines some of the key technical, institutional, policy and financial responses required to achieve climate-smart agriculture which sustainably increases productivity, resilience (adaptation), reduces/removes Greenhouse Gases (mitigation), and enhances achievement of national food security and development goals. Building on case studies from the field, the paper outlines a range of practices, approaches and tools aimed at increasing the resilience and productivity of agricultural production systems, while also reducing and removing emissions.
