An agent-based model of agricultural innovation, land-cover change and household inequality: the transition from swidden cultivation to rubber plantations in Laos PDR

Journal Articles & Books
Diciembre, 2011
Laos

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.

Agricultural land conversion and its effects on farmers in contemporary Vietnam

Journal Articles & Books
Diciembre, 2009
Viet Nam

Đổi Mới, the name given to the economic reforms initiated in 1986 in Vietnam, has renewed the party-state’s ambitious scheme of industrialization and has intensified the process of urbanization in Vietnam. A large area of land has been converted for these purposes, with various effects on both the state and society. This article sheds light on how land conversion has resulted in farmers’ resistance and in what way and to what extent it has transformed their livelihoods in the transitional context of contemporary Vietnam.

The Gap Between Policy and Practice in Lao PDR

Journal Articles & Books
Diciembre, 2008
Laos

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.

From Agriculture to Nutrition: Pathways, Synergies and Outcomes

Reports & Research
Diciembre, 2007
Global

In a world of food abundance, millions of people suffer from poor nutrition. In some parts of the world, the poor have inadequate access to energy from food to meet their energy requirements. In these locations, food shortage is often a seasonal phenomenon and micronutrients are also generally lacking in the diet. Elsewhere, there is a stable supply of energy but the poor have monotonous diets lacking in essential micronutrients.

Global biomass production potentials exceed expected future demand without the need for cropland expansion

Peer-reviewed publication
Octubre, 2015
Global

Global biomass demand is expected to roughly double between 2005 and 2050. Current studies suggest that agricultural intensification through optimally managed crops on today's cropland alone is insufficient to satisfy future demand. In practice though, improving crop growth management through better technology and knowledge almost inevitably goes along with (1) improving farm management with increased cropping intensity and more annual harvests where feasible and (2) an economically more efficient spatial allocation of crops which maximizes farmers' profit.

Closing Yield Gaps: How Sustainable Can We Be?

Peer-reviewed publication
Mayo, 2015
Global

Global food production needs to be increased by 60–110% between 2005 and 2050 to meet growing food and feed demand. Intensification and/or expansion of agriculture are the two main options available to meet the growing crop demands. Land conversion to expand cultivated land increases GHG emissions and impacts biodiversity and ecosystem services. Closing yield gaps to attain potential yields may be a viable option to increase the global crop production. Traditional methods of agricultural intensification often have negative externalities.

Global food demand and the sustainable intensification of agriculture

Peer-reviewed publication
Septiembre, 2011
Global

Global food demand is increasing rapidly, as are the environmental impacts of agricultural expansion. Here, we project global demand for crop production in 2050 and evaluate the environmental impacts of alternative ways that this demand might be met. We find that per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960. This relationship forecasts a 100–110% increase in global crop demand from 2005 to 2050.

Exploring the biophysical option space for feeding the world without deforestation

Peer-reviewed publication
Marzo, 2016
Global

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.

Climate change and agriculture: Strengthening the role of smallholders

Peer-reviewed publication
Febrero, 2016
Global

Smallholder farmers have a vital role to play in global food security and nutrition, and in supporting a range of development and climate change goals. Strengthening the resilience and commercial viability of these farmers, particularly women and youth, can increase their capacity to contribute to these global goals.

Investing in Smallholder Agriculture for Food Security

Reports & Research
Mayo, 2013
Global

In October 2011, the Committee on World Food Security (CFS) requested the High Level Panel of Experts (HLPE) to prepare "a comparative study of constraints to smallholder investment in agriculture in different contexts with policy options for addressing these constraints, taking into consideration the work done on this topic by IFAD, and by FAO in the context of COAG, and the work of other key partners.

Land Rights and Agricultural Productivity

Policy Papers & Briefs
Marzo, 2012
Global

Property rights to land represent the key institutional asset on which rural people build their livelihoods. In fact, in many countries, landlessness is the best predictor of poverty. The nature of farmers’ property rights to land substantially impacts their willingness and ability to adopt productivity-enhancing inputs and investments.

The impact of climate change on smallholder and subsistence agriculture

Reports & Research
Febrero, 2007
Global

Some of the most important impacts of global climate change will be felt among the populations, predominantly in developing countries, referred to as ‘‘subsistence’’ or ‘‘smallholder’’ farmers. Their vulnerability to climate change comes both from being predominantly located in the tropics, and from various socioeconomic, demographic, and policy trends limiting their capacity to adapt to change.
