Malawi

Land degradation and soil erosion have emerged as serious challenges to smallholder farmers throughout southern Africa. To combat these challenges, conservation agriculture (CA) is widely promoted as a sustainable package of agricultural practices. Despite the many potential benefits of CA, however, adoption remains low. Yet relatively little is known about the decision-making process in choosing to adopt CA. This article attempts to fill this important knowledge gap by studying CA adoption in southern Malawi.

Окончание срока выполнения Целей развития тысячелетия подчеркнуло поразительные успехи, достигнутые с 1990 года: доля людей, живущих в крайней нищете, уровень детской смертности и масштабы голода сократились почти вдвое. Однако по-прежнему остаются огромные проблемы.

Soil and land management are essential for a sustainable food supply and ecosystems. Healthy soils can support sustainable agricultural production, mitigation of the impacts of climate change, and other ecosystem services. Interventions that show promise for improving soil health include investment in sustainable intensification technologies, climate-smart agriculture, and ecosystem-level management.

كان عام 2015 لحظة فارقة لمجتمع التنمية الدولية. فلقد ابرزت نهاية الاهداف
الانمائية للألفية التقدم الملحوظ والمحقق لتلك الاهداف منذ عام 1990 ، حيث
انخفضت معدلات الجوع والفقر المدقع ووفيات الأطفال إلى النصف، ومع ذلك تظل هناك
تحديات جسيمة. يستعرض تقرير السياسة الغذائية العالمية لعام 2016 الاتجاهات والاحداث
والتغيرات الكبرى التى تؤثر على الأمن الغذائي والتغذية في عام 2015 وما بعدها؛ كما
يناقش كيف يمكن للنظام الغذائي العالمي أن يساهم فى المزيد من خفض معدلات حدة الفقر،
والجوع، وسوء التغذية مع ضمان الاستخدام المستدام لموارد العالم. وسوف يكون عام 2016

L’année 2015 a marqué un tournant décisif pour la communauté internationale du développement. L’aboutissement des Objectifs du Millénaire pour le développement a souligné les avancées remarquables enregistrées depuis 1990 : l’extrême pauvreté, la mortalité infantile et la faim ont toutes chuté à peu près de moitié. Toutefois, un défi considérable demeure.

Los Biocombustibles y la Seguridad Alimentaria

Policy Papers & Briefs
Dezembro, 2008

La demanda de biocombustibles se está incrementando debido a la necesidad cada vez mayor de energéticos, el alza en el costo del petróleo, la búsqueda de fuentes de energía renovables y no contaminantes y el deseo de aumentar los ingresos agrícolas en los países en desarrollo. Asimismo, ha aumentado en forma drástica la necesidad de contar con cultivos, como el maíz y la caña de azúcar, que pueden utilizarse como materia prima para producir biocombustibles. Esta demanda ha tenido a nivel mundial un impacto significativo y cada vez mayor en los sistemas alimentarios.

África do Sul

Although wild natural resources are a standard dietary component in southern Africa, little information exists on these resources' specific role in the maintenance of household food security among HIV-impacted households. In this context, the influence of cash savings or income generated through use or sale of natural resources (e.g., using fuelwood instead of electricity to be able to afford to buy food) is also not known.

Burkina Faso

"This paper describes the emergence of improved traditional planting pits (zaï) in Burkina Faso in the early 1980s as well as their advantages, disadvantages and impact. The zaï emerged in a context of recurrent droughts and frequent harvest failures, which triggered farmers to start improving this local practice. Despair triggered experimentation and innovation by farmers. These processes were supported and complemented by external intervention. Between 1985 and 2000 substantial public investment has taken place in soil and water conservation (SWC).

Strategies for sustainable natural resource management

Policy Papers & Briefs
Dezembro, 2004

This brief describes two case studies as follows: "Sub-Saharan Africa, with the highest fertility rate in the world, faces increasing demographic pressure on its natural resource base.... Old strategies for coping with these new pressures on the natural resource base are becoming increasingly infeasible... Consequently, Africa's farmers require new solutions to address the increasing pressure on the continent's soil and water resources. Among hundreds of innovative efforts across the continent, two promising sets of responses have emerged in different locations....
