The global food system will experience an unprecedented combination of pressures over the next 40 years. Global population size will increase and competition for land, water and energy will intensify, while the effects of climate change will become increasingly apparent. Over this period, globalisation will continue, exposing the food system to novel economic and political pressures.This final report of the Foresight Global Food and Farming Futures Project argues that decisive action needs to take place now. The report identifies five considerable challenges ahead:

Adoption and extent of conservation agriculture practices among smallholder farmers in Malawi

Janvier, 2014
Malawi

Understanding factors affecting farmers’ adoption of improved technologies is critical to success of conservation agriculture (CA) program implementation. This study, which explored the factors that determine adoption and extent of farmers’ use of the three principles of CA (i.e., minimum soil disturbance, permanent soil cover with crop residues, and crop rotations), was conducted in 10 target communities in 8 extension planning areas in Malawi. The primary data was collected using structured questionnaires administered to individual households.

Adaptation of land-use demands to the impact of climate change on the hydrological processes of an urbanized watershed

Décembre, 2011
Taiwan
Asie orientale
Océanie

The adaptation of land-use patterns is an essential aspect of minimising the impact of climate change at regional and local scales; for example, adapting watershed land-use patterns to mitigate the impact of climate change on a region’s hydrology. The aim of this study is to simulate and assess a region’s ability to adapt to hydrological changes by modifying land-use patterns in the Wu-Du watershed in northern Taiwan.

Toolkit: integration of biodiversity concerns in climate change mitigation activities

Décembre, 2003

This toolkit provides a practical guide on designing climate change mitigation activities. The toolkit aims to enhance synergies between climate change mitigation and biodiversity conservation policies.The first part of the toolkit gives an overview of possible climate change mitigation activities, especially in the land use, land use change and forestry sector.

Voluntary guidelines on the responsible governance of tenure of land, fisheries and forests in the context of national food security

Manuals & Guidelines
Décembre, 2011
Global

Tackling the issue of land and resource tenure is one of the prerequisites for mechanisms such as REDD+ to have positive impacts not only on reducing emissions from the forestry sector but also in reducing poverty and achieving food security. These new guidelines by the Committee on World Food Security (CFS) outline principles and practices that governments can refer to when making laws and administering land, fisheries and forests rights.

Soil carbon management in large-scale Earth system modelling: implications for crop yields and nitrogen leaching

Décembre, 2015

Results demonstrate that the effects of management on cropland can be beneficial for carbon and nutrient retention without risking (large) yield losses.

Nevertheless, effects on soil carbon are small compared with extant stocks in natural and semi-natural ecosystem types and managed forests.

While agricultural management can be targeted towards sustainable goals, from a climate change or carbon sink perspective avoiding deforestation or reforestation constitutes a far more effective overall strategy for maintaining and enhancing global carbon sinks.

Mainstreaming climate-sensitive indicators into an existing food monitoring system: climate change and food security in Nepal

Janvier, 2013
Népal
Asie méridionale

In 2011, the Government of Nepal made its policy on climate change public. The policy envisions a country “spared from the adverse impacts of climate change, by considering climate justice, through the pursuit of environmental conservation, human development, and sustainable development [with] all contributing toward a prosperous society”. This objective of making Nepal and Nepali society more resilient to climate change is laudable, especially as emerging evidence suggests that Nepal and its people are likely to be very vulnerable to the impacts of climate change.

Philippine landcare after nine years: a study on the impacts of agroforestry on communities, farming households, and the local environment in Mindanao

Décembre, 2005
Philippines

This paper reviews the impact of the Landcare Program on, farming households, communities, and the local environments in three sites in Mindanao, Philippines: Claveria in Misamis Oriental; Lantapan in Bukidnon; and Ned, Lake Sebu in South Cotabato. This paper reviews and synthesizes various studies conducted throughout the period from 1996 to 2004, during which the Landcare Program was established and matured. The key intervention studied is the landcare approach which consists basically of two components: conservation farming technologies and landcare processes and institutions.

Current estimates of climate change state that the world’s average temperature is due to increase by at least 2oC to 2.4oC over the next 50?100 years. Furthermore it is expected that by the end of the century a range of additional impacts will be felt: sea levels will rise by an estimated 60cm, resulting in flooding and the salinisation of fresh water aquifers, and snow and ice cover will decrease. Simultaneously, precipitation patterns will change so that some areas will receive large increases whilst other areas will become hotter and drier.

Vulnerability of arid and semi-arid regions to climate change: impacts and adaptive strategies

Décembre, 2008

This perspective document, part of the 16-paper series on water and climate change adaptation, focuses on the impacts and adaptive strategies in arid and semi-arid regions. The series reflect the central topic of the 5th World Water Forum, ‘climate change and adaptation’, where it was presented and discussed. The following risks posed by climate change to the water sector in arid regions are identified.

It has emerged quite clearly from Urban LandMark’s work in South Africa – and increasingly in the region – that the emergence of more sophisticated property markets has taken place locally and in most larger cities in the region. While there might be a need to assist these markets to develop further, in particular the need to build market institutions and professions, these groupings tend to increase their own capacities as the markets develop, mostly with little assistance.

Seizing the global opportunity: Partnerships for better growth and a better climate – the 2015 new climate economy report

Janvier, 2015

With 2015 representing a year of unprecedented opportunity with regard to the landmark intergovernmental conferences on development and climate action, the Global Commission on the Economy and Climate have produced this substantial report which makes the case for all parties to forge new and improved strategic partnerships for economic growth and a better climate.The first part of the report focuses on new opportunities and challenges for low-carbon growth and international cooperation, examining recent trends and developments, and international cooperation both within and without the UNFCC
