Estimates of the percent of Earth's land surface that has either been transformed or degraded by human activity range between 39 and 50 percent, with agriculture accounting for the vast majority of these changes. Although much of the focus of research on land use and cover change in the tropics has been on deforestation, ongoing socioeconomic changes both locally and globally have made land transitions in the tropics extremely fluid. In addition, feedbacks between land cover change and human behavior constrain the extent and trajectories of land transitions.

There has been considerable discussion over the past thirty years on how to define “sustainable agriculture.” During most of this period, sustainability was exclusively considered an environmental issue and was therefore measured as such. The 2030 Agenda requires that all sectors, including agriculture, be considered from the point of view of the three dimensions of sustainability: economic, social and environmental.

Over the coming 35 years, agriculture will face an unprecedented confluence of pressures, including a 30 percent increase in the global population, intensifying competition for increasingly scarce land, water and energy resources, and the existential threat of climate change. To provide for a population projected to reach 9.3 billion in 2050 and support changing dietary patterns, estimates are that food production will need to increase from the current 8.4 billion tonnes to almost 13.5 billion tonnes a year.

On 25 September 2015, the 193 Member States of the United Nations adopted the 2030 Agenda for Sustainable Development – including 17 Sustainable Development Goals (SDGs) and 169 targets – committing the international community to end poverty and hunger and achieve sustainable development between 2016 and 2030. Six months later, a global indicator framework for the SDGs – comprising 230 indicators - was identified to monitor the 169 targets and track progress, becoming the foundation of the SDGs’ accountability structure.

Sustainable agricultural mechanization (SAM) is an essential input for the development of the smallholder farm sector in sub-Saharan Africa (SSA). The benefits of SAM range from drudgery reduction to improved timeliness of agricultural operations, increased input use efficiency, facilitating sustainable production intensification, ensuring environmental protection, and contributing to make agriculture more ‘climate-smart’. SAM is also important at other levels of the food supply system, for example in post-harvest operations, processing, marketing and transportation.

This report addresses the economic, environmental and social dimensions of agricultural development, with the objective of ensuring food and nutrition security, in terms of availability, access, utilization and stability. It focuses on the livestock component of agricultural systems, given the role of livestock as an engine for the development of the agriculture and food sector, and as a driver of major economic, social and environmental changes in food systems worldwide.

This paper is specifically about agricultural mechanisation: the opportunities provided by mechanisation for intensifying production in a sustainable manner, in value addition and agri-food value chain development, as well as the inherent opportunities implied for improved local economies and livelihoods. The establishment of viable business enterprises agro-processors, transport services, and so forth as a result of increased agricultural mechanisation in rural areas, is crucial to creating employment and income opportunities and, thereby, enhancing the demand for farm produce.

Recent expansion of the scale of human activities poses severe threats to Earth’s life-support systems. Increasingly, protected areas (PAs) are expected to serve dual goals: protect biodiversity and secure ecosystem services. We report a nationwide assessment for China, quantifying the provision of threatened species habitat and four key regulating services—water retention, soil retention, sandstorm prevention, and carbon sequestration—in nature reserves (the primary category of PAs in China).

The 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs) set out the international community’s commitment to rid the world of poverty and hunger and achieve sustainable development in its three dimensions – economic, social and environmental.

China’s investment and trade in Africa’s natural resource sectors have significant implications for Africa’s forests. Many investments are in forest areas. Some directly engage in logging while others, such as mining, infrastructure and agribusiness, affect forests and rural livelihoods. This report provides an overview of trends, evidence and issues related to the impacts on forests of Chinese investments in four African countries: Cameroon, Democratic Republic of Congo, Mozambique and Uganda.

Mozambique is Africa’s largest exporter of timber to China. Yet multiple published concerns over the sustainability and legality of that timber trade assert the rapid commercial depletion of future timber stocks, the marginalisation of local forest communities, and the loss of revenue to government estimated at US$146 million between 2007 and 2013 alone.
