Poplars and willows provide society with ecosystem services. These include direct economic benefits such as wood, fibre, fuelwood and other forest products. They also include environmental benefits improving the lives of people, such as through rehabilitation of degraded land, restoration of forest landscapes and mitigation of climate change. All of these services support rural livelihoods, enhance food security, alleviate poverty and contribute to sustainable land use and rural development, particularly in developing countries.

The province of Punjab is the main food basket of India. In recent years, many regions of Punjab are facing acute waterlogging problems and increased secondary salinity, which have negative impacts on food security of the nation. In particular, these problems are more pronounced in the Muktsar district of Punjab. The observed groundwater levels trend between 2005 and 2011 implies that groundwater levels are coming towards the land surface at the rate of 0.5 m/year in Lambi and Malout blocks.

Reliance on rainfall for agriculture and increased climate change and variability pose growing production risks in developing countries. Agriculture in Sub-Saharan Africa is dominated by smallholder farmers who depend mainly on rain-fed agriculture, putting food security at both household and national levels at risk, especially in the event of drought. Investment in smallholder irrigation becomes a priority in developing countries if food security and national development goals are to be met, as their economies are agro-based.

This review outlines livestock's major emission pathways and production trends, and explores the challenges and options for livestock in addressing and coping with climate change. Ruminant production is, and will continue to be, the chief source of the livestock sector's greenhouse gas (GHG) emissions, mainly as a result of deforestation, land degradation and enteric fermentation.

Modeling human–environment systems presents many challenges, including incorporating structure and agency and addressing uncertainty in system components and relationships. Exploring perceptions not only gives us insight into decision-making (agency) but also reveals structural constraints influencing those decisions (including perceived constraints). This study focuses on the human–nature dynamics of Fanjingshan National Nature Reserve (FNNR) in China, a biodiversity hotspot and the only habitat for the Guizhou golden monkey (Rhinopithecus brelichi).
