An international review of forestry and forest products
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.
Shifting cultivation, under its diverse forms of slash and burn system, is a traditional method of cultivating tropical upland soils, mostly for subsistence purposes. This traditional system of cultivation is in ecological balance with the environment and does not irreversibly degrade the soil resource, provided a sufficient length of fallow is allowed for soil restoration. However, increasing population pressures necessitate more intensive use of land. The consequence is extended cropping periods and shortened fallows.
