A história da agricultura mundial no último meio século tem sido, sobretudo, a história de transformações produtivas, impulsionadas pela ciência e pela intensificação tecnológica, e a resultante expansão da capacidade produtiva, pari passu com o crescimento da demanda de alimentos.

It is undoubtedly a challenge for climate policy actors to identify reliable evidence to support sound decision-making processes for tackling climate issues effectively. Still, differentiating between fact and fiction, well-designed and invalid science, evidence- or interest-based arguments is precisely what determines the quality of climate policies.

This year's 2nd edition of the European Security and Defence Union journal is looking into climate change as global security and humanitarian challenge. Janani Vivekananda, Senior Adviser for Climate Change and Peacebuilding at adelphi, has contributed to the journal with a piece on the climate security crisis currently plaguing the Lake Chad basin. Lake Chad is a geophysical and ecological miracle.

Shortly after releasing a report on its climate change strategy in July 2017, the Food and Agriculture Organization (FAO) of the United Nations presents a new report at COP23 - this time focusing on the organization's concrete work on climate change.

Climate change in Afghanistan is not an uncertain, “potential” future risk but a very real, present threat— whose impacts have already been felt by millions of farmers and pastoralists across the country. In this report, it is shown how drought and flood risks have changed over the past thirty years, and what impact this has had on rural livelihoods and food security in the country. The aim is to inform national-level prioritisation of areas and livelihoods groups for climate change adaptation and disaster risk reduction programmes.

Despite six years of crisis in Syria, agriculture remains a key part of the economy. The sector still accounts for an estimated 26 percent of gross domestic product (GDP) and represents a critical safety net for the 6.7 million Syrians – including those internally displaced - who still remain in rural areas. However, agriculture and the livelihoods that depend on it have suffered massive loss. The Food and Agriculture Organization of the United Nations (FAO) has now conducted the first comprehensive nationwide assessment on the cost of the war to the agriculture sector.

The Sendai Framework for Disaster Risk Reduction (DRR) is a non-legally binding agreement designed to reduce existing levels of risk and prevent emerging risks. While references to conflict were deleted from the final text, Sendai addresses issues parallel to those that would need to be addressed in a prevention and sustaining peace agenda.

The Framework, if properly implemented, would tackle three sets of factors that increase both disaster and conflict risks:

Land is already under growing human pressure and climate change is adding to these pressures. The Special Report on Climate Change and Land, launched by the Intergovernmental Panel on Climate Change (IPCC) on 8 August 2019, looks into land resources as critical for the climate, and highlights the importance of sound land management for addressing climate change. The report will be a key scientific input into forthcoming climate and environment negotiations.

This report combines the conclusions of several scientific studies and the opinions of numerous researchers and specialized organizations that have focused these past few years on the link between climate and security. It highlights the essential contributions of a collective group of experts in order to concentrate on this issue and encourage institutions such as foreign and defense ministries to adopt new approaches.

As water is the most disruptive element in the ongoing climate crisis, how land is managed plays a major role in taming this disruption. This publication shows that avoiding, reducing and reversing land degradation can have positive long-term gains in water security.

Internal climate migrants are rapidly becoming the human face of climate change. According to this new World Bank report, without urgent global and national climate action, Sub-Saharan Africa, South Asia and Latin America could see more than 140 million people move within their countries’ borders by 2050.

As an international actor in addressing food insecurity among refugees and other migrants, the World  Food Programme (WFP) has undertaken a research study to determine the role that food security plays in cross-border migration. Given the dearth of data on this topic, the WFP  study sought to answer some of the following questions: What is it that compels people to leave their homes? What role does food insecurity play in migration? Are these factors common across all international migrants, or do unique root causes spur specific migrant populations to move from their homes?
