This paper seeks to map out the historical trajectory leading to a series of migrations in and from the erstwhile princely state of Travancore during 1900-70 in order to acquire and bring land under cultivation. It argues that these migrations undertaken with a moralistic and paternal mission of reclaiming ‘empty’ spaces into productive locations were a result of a specific form of economic modernity in Kerala as beckoned by colonialism and appropriated by a resolute local agency through a process of translation.

This paper looks for the possible explanations for the land productivity differential between high caste and low caste farm households in Nepal. The paper indicates that caste position still plays a vital role in rural areas of Nepal.The paper finds that: land productivity is higher among low caste households. However, in case of owner-operated plots, the land productivity differential between low caste and high caste is found to be insignificant after controlling for land quality and household characteristics. This difference remains highly significant in case of rented in plots.

Traditionally, agricultural diversification is referred to a subsistence kind of farming wherein farmers were cultivating varieties of crops on a piece of land and undertaking several enterprises on their farm portfolio.

In Vietnam, forest devolution policies were implemented in the early 1990’s under which the government transferred management power over large areas of forested land previously controlled by the state forest enterprises or local authorities to local households. The government believes that implementing devolution policies would improve local livelihoods for the upland poor and stabilize forest conditions to increase forest cover.

The report includes three essays about Responding to the World Food Crisis: Getting on the Right Track by Joachim von Braun, High Global Food Prices: The Challenges and Opportunities by Josette Sheeran, and Policy Implications of High Food Prices for Africa by Namanga Ngongi.

"African agriculture is at a crossroads. The current high food prices and the instability they have provoked in several countries have added impetus for African countries to review their agricultural policies and programs. New agricultural policies will have to be more focused on staple food crops and on their main producers-smallholders, most of whom are women. The new policies must remove constraints that impede access by smallholder farmers to the knowledge, technology, and financial services they need to increase farm productivity in a profitable and environmentally sustainable manner.

High food prices are not only causing a humanitarian crisis, but also putting at risk the development potential of millions of people. Global agriculture markets are undergoing structural changes, and the next three to four years will pose great challenges for achieving an affordable and accessible food supply for the world's most vulnerable. Soaring food and fuel prices are creating a "perfect storm" for the world's most vulnerable.
