Safeguarding the world’s remaining forests is a high-priority goal. We assess the biophysical option space for feeding the world in 2050 in a hypothetical zero-deforestation world. We systematically combine realistic assumptions on future yields, agricultural areas, livestock feed and human diets. For each scenario, we determine whether the supply of crop products meets the demand and whether the grazing intensity stays within plausible limits. We find that many options exist to meet the global food supply in 2050 without deforestation, even at low crop-yield levels.

This article examines the transition from shifting cultivation to rubber production for a study area in northern Laos PDR using an agent-based model of land-cover change. A primary objective of the model was to assess changes in household-level inequality with the transition from shifting cultivation to rubber adoption. A secondary objective was to develop explanations for the rate of rubber adoption in the study area.

ABSTRACTED FROM THE OPENING PARAGRAPHS, AND THE BOOK BLURB: The decentralization of control over the vast forests of the world is moving at a rapid pace, with both positive and negative ramifications for people and forests themselves. Th[is] chapter examines LFA from the decentralized forest management perspective. In particular, it examines the process by which the policy was implemented and considers whether it helped build sustainable forest management at the community level. [It] first reviews the history of LFA and the major actors involved.

The Lao Land and Forest Allocation Policy (LFAP) was intended to provide clearer property rights for swidden farmers living in mountainous areas. These lands are legally defined as “State” forests but are under various forms of customary tenure. The policy involves demarcating village territorial boundaries, ecological zoning of lands within village territories, and finally allocating a limited number of individual land parcels to specific households for farming.

Although the commercial cultivation of genetically modified (GM) plants in Africa has been relatively modest until now, a number of research and development projects in this field are already operating in several African countries. These involve breeding drought-tolerant, pest-resistant or nutrient-enriched maize, or cassava varieties with greater disease and pest resistance. 

The System of Rice Intensification (SRI) is a natural resource management technology that has supporters and opponents. Evidence of the technology’s impacts is mixed. Recent research results from Timor Leste suggest that SRI can improve yields and incomes of smallholder farmers when proper extension systems are in place.

Zimbabwe used to be well-known for its high-quality meat exports. The sector was hard hit by the economic crisis that set in during the 1990s and coincided with the impact of a failed land reform and recurrent drought. Now, a new livestock-fattening scheme is to contribute to the survival of the branch and help resource-poor smallholders earn a living by marketing their meat.

Not only has soil degradation in Niger been halted thanks to an integrated approach combining water harvesting technologies, the application of organic residues and planting of fruit trees and vegetables. The strategy has also enabled increases in farmers’ income as well as an active involvement of the country’s largely marginalised women in food production through their gaining access to land.

Soil carbon is important for soil structure and related nutrient and water holding properties. Increasing soil carbon stocks results in improved crop growth and contributes to enhanced climate resilience. In addition, the increase in soil organic carbon through sustainable agricultural land management (SALM) practices, such as the use of cover crops, residue management and agroforestry, will also reduce the need for synthetic nitrogen fertiliser at a given level of crop production.

More than three times as much carbon is stored in soils across the world as it is in the atmosphere, making them one of the most important global carbon sinks. Therefore, processes impacting on the soil in which carbon is released, such as deforestation or agricultural activities, significantly contribute to climate change. The debate on the reduction of greenhouse gas emissions from agricultural activities and their consideration in the international climate negotiations has brought soils as carbon reservoirs more to the public eye.

Crop yield improvement is dearly needed in sub-Saharan Africa, but remarkably, African farmers do not adopt the available ‘Green Revolution’ fertiliser technologies. This has many reasons, a crucial one being soil properties.

Cassava is the main staple crop in many African countries, but the crops are threatened by two major diseases, the cassava mosaic virus disease and cassava brown streak virus, which in the last years have destroyed almost 80 percent of cassava harvests in Africa.
