    The purpose of this book is to document the effects of climate change on agriculture in Africa and to discuss strategies for adaptation to hotter weather and less predictable rainfall. These strategies include promoting opportunities for farmers to adopt technologies that produce optimal results in terms of crop yield and income under local. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.

    The analysis of the three areas according to their level of agricultural intensification showed, for the – period, an increasing trend of the NDVI in the three areas, although it was higher in areas which remained stable in their land use intensity, and showed lower values in areas where intensification was : Inés Gazzano, Marcel Achkar, Ismael Díaz.   Agricultural areas cover approximately 40 % of our planet’s terrestrial ecosystems (FAOSTAT ), with the 5 billion ha of land under farming and grazing now surpassing the extent of the world’s forested areas (Robertson and Swinton ; Power ).Agricultural areas are expected to continue to expand with increasing human population growth and resultant resource use: Low- and Cited by:

      Intensification to Reduce Deforestation. Agricultural intensification—increasing agricultural inputs to improve per-hectare yields rather than expanding land under cultivation—is often posited as a strategy for reducing agriculture encroachment into forest, while satisfying agricultural demand (4 –8).Intensification purportedly creates a “virtuous cycle of poverty reduction and reduced. The seemingly better area is the hillside area of Honduras because springs and good access to a large city made intensification a reality. The problems are of different nature in each site. The African villages have the greatest challenges since population growth requires intensification and that intensification under warm climate is more.

Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices.

The book includesAuthor: Board on Agriculture. Agricultural intensification, deforestation and the environment: assessing tradeoffs in Sumatra, Indonesia. The chapter reports on empirical results from study sites on the island of Sumatra, Indonesia. The area was chosen to represent the lowland humid tropical forest zone in Asia for the global Alternatives to Slash and Burn project (ASB).

In recent years, as a way to achieve higher agricultural output while reducing the negative impact of agricultural production on the environment, agricultural sustainable intensification has attracted worldwide attention. Under the framework of "connotation definition-measuring method-influencing factor-implementation path", this paper systematically sorts out the main research results in the Cited by: 1.

spare land is a sign of ineffective environmental conservation. intensification of agriculture and land use would tend to spare land for biodiversity conservation. it is actively debated whether spare land is low or high in biodiversity.

there are still ample areas of wilderness-type areas suitable for biodiversity conservation. Under the theory of intensification of farming systems of Boserup,Ruthenberg, a, Ruthenberg, b, the BR model of intensification, both population growth and market access can lead to a virtuous cycle of intensification of agriculture: These forces lead to a reduction in fallow, higher use of organic manure and fertilizers to offset declining soil fertility, and investments in mechanization, Cited by: On the one hand, given that the intensification and extensification of agriculture to feed the growing human population are responsible partly for today's global environmental problems [68], the.

In tropical Mexico and throughout the nation, deforestation is not only an ecologic concern but also an indicator of much wider social, political, and economic factors. It is the result. The humid highlands in sub-Saharan Africa (SSA) are characterized by high population densities and require intensification.

The intensification of agriculture has led to widespread reduction of species and habitats. However, about two-fifths of the EU's agricultural area remains under low intensity systems - mainly either grazing land under various systems of livestock management or permanent crops under traditional management.

When agricultural intensification is realized at the landscape level, a significant loss and/or fragmentation of natural and semi-natural habitat is often the consequence.

A number of studies have explored the persistence of biological control in relation. It is widely believed that sustainable intensification has the characteristics of increasing production and reducing environmental damage, and is widely used in agricultural, biological and.

Other policies will help to reduce the conflict between agricultural intensification and environmental protection. Tighter regulations and national strategies on the management of animal waste and the use of chemical fertilizers and pesticides may be required, along with the removal of subsidies on chemical and fossil energy inputs.

Tropical ecosystems sustain much of Earth's biological diversity [1], provide myriad natural products and services to local communities [2], and play key roles in the global carbon and hydrological cycles [3,4].

Unfortunately, many tropical ecosystems are being disrupted by large-scale land-use change and other environmental alterations [5]. Such changes are an important source of greenhouse Cited by:. Ecological Intensification includes building natural capital, precision agriculture and diversification.

Natural capital (the biophysical assets within the natural environment that deliver economic value through ecosystem services) [6] can be conserved and enhanced through a variety of approaches, including organic agriculture, water conservation and conservation agriculture.Agricultural intensification is a process that involves both societal (social, political, and economic) and environmental processes of change, and it has been an important research topic in geography, particularly during the second half of the 20th century.

The results obtained shed further light on the role of governance and agricultural intensification on agricultural expansion in tropical South America.

With respect to the effect of conventional governance factors on agricultural expansion and deforestation, the existing literature reports contrasting results (25 – 27).Cited by:
